ABSTRACT

Objective:To investigate the surgical method of LC-II screws for fragility fractures of the pelvis (FFP) in the elderly and evaluate its clinical efficacy.Methods:A retrospective analysis was performed on 45 patients with FFPs operated in our department from January 2011 to January 2022. The clinical information was as follows. The FFP classification of pelvic fracture was IIIA in 26 cases and IIIB in 19 cases. Among them, 22 cases were fixed with closed reduction and modified LC-II screws (experimental group), and 23 cases were fixed with open reduction and reconstruction plates (control group). In the experimental group, there were 6 males and 16 females. The age range was 62-90 years, with an average of 73.2±9.2 years. The FFP classification of pelvic fracture was IIIA in 12 cases and IIIB in 10 cases. In the control group, there were 8 males and 15 females. The age range was 60-87 years, with an average of 72.8±6.6 years. FFP classification of pelvic fracture was IIIA in 14 cases and IIIB in 9 cases. After admission, pelvic X-ray and CT scan were performed, and the surgery was prepared. In the experimental group, after closed reduction of the posterior ring, the modified LC-II screw was inserted below the anterior inferior iliac spine (AIIS) toward the sacroiliac joint and penetrated the sacroiliac joint. For combined anterior ring fractures, the INFIX was used for anterior ring fixation. In the control group, the posterior ring was fixed with a reconstruction plate and/or sacroiliac screw after open reduction through the lateral rectus approach (LRA). The clinical efficacy was evaluated between the experimental group and the control group.Results:All 45 patients were successfully operated and followed up for 6 months to 3 years. All the pelvic fractures healed. In the experimental group of 22 cases, the time from injury to operation was 3-9 days, with an average of 5.8±1.9 days; the operation time was 25-70 min, with an average of 42.0±12.9 min. The intraoperative bleeding was 20-40 ml, with an average of 29.1±6.7 ml. According to the X-ray reduction evaluation criteria of Matta, 7 cases were excellent, 11 cases were good and 4 cases were medium, with an excellent and good rate of 81.8%. According to rehabilitation criteria of Majeed, 10 cases were excellent, 6 cases were good and 6 cases were fair, with a total excellent and good rate of 72.7%. At the last follow-up, sacroiliac joint pain was evaluated by VAS score: 0 in 10 cases, <3 in 7 cases, and 4-6 in 5 cases. No internal fixation loosening occurred. In the control group, the time from injury to operation was 5-20 days, with an average of 9.9±3.8 days; the operation time was 50-150 min, with an average of 89.1±29.5 min; the intraoperative bleeding was 220-1 000 ml, with an average of 509.2±214.3 ml. According to the X-ray reduction evaluation criteria of Matta, 16 cases were excellent, 4 cases were good and 3 cases was medium, with an excellent and good rate of 87.0%. According to rehabilitation criteria of Majeed, 12 cases were excellent, 6 cases were good and 7 cases were fair, with a total excellent and good rate of 78.3%. At the last follow-up, sacroiliac joint pain was evaluated by VAS score: 0 in 14 cases, <3 in 6 cases, and 4-6 in 3 cases. In the control group, posterior ring plate loosening was found in 2 cases and anterior ring pubic ramus plate and screw loosening was found in 4 cases, but there was no reduction loss.Conclusion:The modified LC-II screw is theoretically feasible in the treatment of FFP. Preliminary clinical results show good safety and efficacy, providing a new idea for minimally invasive treatment of FFP.

ABSTRACT

Objective:To explore the surgical methods and treatment effects of adult anterior dislocation of the sacroiliac joint (AADSJ).Methods:A multi-center retrospective case series study was conducted to analyze the clinical data of 25 cases admitted in 5 clinical centers (affiliations of authors in this article) from January 2016 to January 2021. There were 18 males and 7 females, aged 38.8±15.5 years (range, 18-83 years). The AADSJ clinical classification system was formulated based on the radiographic morphology of anterior dislocation of the sacroiliac joint, which includes two types. Type I: complete anterior dislocation of the sacroiliac joint, and displacement of the entire iliac auricular surface to the front of the sacrum. Type II: fracture of the sacroiliac joint combined with anterior dislocation, subdivided into 3 subtypes. Type IIa: iliac fracture involves the anterior 1/3 of the sacroiliac joint, and dislocation of the ilium anterior to the sacrum. Type IIb: iliac fracture involves the posterior 2/3 of the sacroiliac joint, and dislocation of the ilium anterior to the sacrum. Type IIc: iliac fracture involves the posterior 2/3 of the sacroiliac joint, and dislocation of the ilium anteromedial to the sacrum. The reliability and repeatability of the clinical classification, Tile classification and Young-Burgess classification were performed based on the results of two-phase assessments in four observers. The operations were performed by the lateral-rectus approach and the ilioinguinal approach. The operation time and intraoperative bleeding were recorded. Pelvic X-ray and CT scan were rechecked after the operation. The quality of fracture reduction was evaluated according to Matta score. The postoperative functional rehabilitation was evaluated according to the Majeed rehabilitation standard at one-year follow-up.Results:Among 25 cases in this study, there were 3 cases of Type I, 5 cases of Type IIa, 9 cases of Type IIb and 8 cases of Type IIc according to the clinical classification system. The Kappa values of reliability tests for the clinical classification, Tile classification and Young-Burgess classification were 0.681, 0.328 and 0.383, respectively. The Kappa values of repeatability tests for the clinical classification, Tile classification and Young-Burgess classification were 0.690, 0.221 and 0.395, respectively. The reliability and repeatability of the AADSJ clinical classification were significantly better than other classifications. There were 14 cases underwent lateral rectus abdominis approach and 11 cases underwent ilioinguinal approach. The operative time for managing anterior dislocation of the sacroiliac joint was 122.0±50.7 min (range, 65-148 min) through the lateral rectus abdominis approach, and through the ilioinguinal approach was 178.0±49.9 min (range, 110-270 min), with a significant difference ( t=2.76, P=0.011). The amount of intraoperative blood loss through the lateral rectus approach was 680±330 ml (range, 350-2,120 ml), which was significantly less than that through the ilioinguinal approach (1,660±968 ml, 680-3,300 ml), with a significant difference ( t=3.55, P=0.002). The follow-up period was 1-3 years. At one week after surgery, the quality of fracture reduction evaluated by Matta score showed that the excellent and good reduction rate of the lateral-rectus approach was 79% (11/14), and that of the ilioinguinal approach was 73% (11/14), with no statistically significant difference ( P=1.000). At a one-year follow-up, according to Majeed's criteria, the overall excellent and good rate of the lateral-rectus approach was 64% (9/14), which is similar to 64% (7/11) of that of the ilioinguinal approach. No fracture reduction loss or internal fixation loosening failure occurred. Conclusion:The AADSJ clinical classification system can accurately describe the imaging features and clinical manifestations of AADSJ, with high reliability and repeatability. The AADSJ can be treated by the lateral-rectus approach or the ilioinguinal approach, with similar therapeutic effects but the former having less trauma.

ABSTRACT

Objective:To evaluate our self-designed pubic symphysis orthotic compression anatomic plate (PSOCAP) in the treatment of fractures and dislocations around the pubic symphysis.Methods:A retrospective study was conducted to analyze the 16 patients with fracture or dislocation around the pubic symphysis who had been treated by our self-designed PSOCAP at Department of Traumatic Surgery, Center for Orthopaedic Surgery, The Third Hospital Affiliated to Southern Medical University from January 2021 to June 2022. There were 8 males and 8 females with an age of (41±19) years. According to the Tile classification for pelvic fractures, there were 3 cases of type B1, 2 cases of type B3, 1 case of type C1.2, 4 cases of type C1.3, 3 cases of type C2, and 3 cases of type C3. There were 8 cases of pubic symphysis separation and 8 fractures of the pubic ramus (2 ones at Nakatani zone Ⅰ and 6 ones at Nakatani zone Ⅱ). Time from injury to surgery was 16 (11, 53) days, ranging from 4 to 348 days. The fractures or dislocations around the pubic symphysis were exposed by the modified Stoppa approach, reduced with the assistance of PSOCAP and fixated with PSOCAP; the posterior pelvic ring was reduced and fixated by corresponding surgical methods. Recorded were the surgical time, intraoperative bleeding, postoperative quality of fracture reduction, surgical complications, and functional recovery at the last follow-up concerning the pelvic anterior ring.Results:Surgery went on successfully in the 16 patients. Their surgical time was (58±15) min, ranging from 40 to 90 min, and their intraoperative bleeding 85 (63, 150) mL, ranging from 50 to 250 mL. According to the Matta scoring, the fracture reduction was evaluated as excellent in 10 cases, as good in 3 cases and as fair in 3 cases. The (10±3)-month follow-up for the 16 patients revealed complete fracture union for all after (12±2) weeks. According to the Majeed scoring at the last follow-up, the pelvic function was evaluated as excellent in 5 cases, as good in 7 cases, and as fair in 4 cases. No such postoperative complications as fracture displacement or internal fixation failure occurred.Conclusion:Owing to the biplane and integrated structure, our self-designed PSOCAP can help reduce the fractures or dislocations around the pubic symphysis to achieve anatomical reduction and strong internal fixation, leading to good clinical efficacy.

ABSTRACT

Objective:To analyze the clinical characteristics of patients with spontaneous low intracranial pressure (SIH).Methods:The study is a retrospective series. The clinical data of patients with SIH who visited Beijing Hospital from May 2017 to March 2022, including gender, age, symptoms, signs, imaging findings, treatment and outcome, were collected and their clinical characteristics were analyzed.Results:Finally, 8 patients with SIH, 6 females and 2 males, aged (33.5±7.3) years, were included. There were 6 cases of acute onset, 1 case of subacute onset, and 1 case of chronic onset. Four cases had pre-onset triggers, 3 cases were exertional and 1 case was exercise. All 8 cases had orthostatic headache. Three cases were accompanied by neck pain. Six cases were accompanied by autonomic dysfunction, 1 case with blurred vision and neck resistance, and 1 case with tinnitus in both ears. There were no obvious abnormalities in blood routine, liver and kidney function, electrolytes, and coagulation function in 8 cases. The results of the lumbar puncture showed that the cerebrospinal fluid pressure was≤60 mmH 2O(1 mmH 2O=0.009 8 kPa) in 7 cases, and 2 cases were so low that they were undetectable. One patient had normal cerebrospinal fluid pressure (90 mmH 2O). The routine results of cerebrospinal fluid showed 4 cases of an increased number of red blood cells and 2 cases of leukocytosis. The biochemical results of cerebrospinal fluid in all 8 cases were normal. All 8 patients underwent non-contrast MRI scan of the head, and 6 cases found abnormalities, including 2 cases of subdural hematoma, 1 case of subarachnoid hemorrhage, 1 case of brain tissue sinking, and 3 cases of intracranial venous sinus dilation (including 1 case with subdural hematoma). All 8 patients underwent MRI enhancement scan of the head, and 5 patients showed diffuse dural enhancement. Three patients underwent digital subtraction angiography myelogram and computed tomography myelogram, and 2 cases found dural cerebrospinal fluid leakage. One patient underwent magnetic resonance water imaging and no cerebrospinal fluid leakage was found. Eight patients were followed up for 38.5 (10.3, 63.0) months, after conservative treatment, 6 cases of headache relief or disappearance, 1 case relapsed and was admitted 1 week after discharge, non-targeted epidural blood patching (EBP) did not relapse, 1 case underwent non-targeted EBP after conservative treatment failure, headache relief, recurrence after 2 months, thoracic spine 3-4 space targeted EBP, headache disappeared, did not recur. Conclusions:The present study indicate that SIH prevalence in young age is common, the main symptom is orthostatic headache, accommodated with multiple clinical symptoms with various imaging abnormalities. Most patients with SIH can be treated conservatively, if the effect is not good, non-targeted or targeted EBP is feasible.

ABSTRACT

Objective:To analyze risk factors for unfavorable outcomes after recanalization of large vessel occlusion (LVO) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS-LVO who underwent recanalization treatment (including intravenous thrombolysis and endovascular intervention) at the Stroke Unit of Beijing Hospital from August 2018 to January 2022 were consecutively enrolled. According to the modified Rankin Scale (mRS) at 90-day follow-up after recanalization treatment, participants were classified as unfavorable outcomes (mRS>2) and favorable outcomes (mRS≤2). Baseline clinical data of enrolled patients was collected, and step-wise multivariate logistic regression analysis was used to identify independent risk factors for unfavorable outcomes after recanalization in AIS-LVO patients.Results:A total of 212 AIS-LVO patients were enrolled, including 86 females (41.35%), with an average age of 72.9 years. There were 75 patients in the favorable outcome group and 137 patients in the unfavorable outcome group. Compared with the favorable outcome group, the unfavorable outcome group had a higher average age, a higher proportion of females and patients with atrial fibrillation, higher baseline NIHSS, higher systolic blood pressure, and higher blood creatinine and D-dimer levels (all P<0.05). After adjusting for age and atrial fibrillation as confounding factors, multivariate logistic regression analysis showed that female ( OR=2.859, 95% CI: 1.202-6.799, P=0.018), higher baseline NIHSS ( OR=14.417, 95% CI: 6.269-33.158, P<0.001), higher pre-treatment systolic blood pressure ( OR=1.034, 95% CI: 1.015-1.054, P=0.001), higher emergency blood creatinine level ( OR=1.378, 95% CI: 1.105-1.719, P=0.005), and higher D-dimer level ( OR=3.594, 95% CI: 1.290-10.014, P=0.014) were independent risk factors for unfavorable outcomes after recanalization treatment in patients with AIS-LVO. Conclusion:Female, higher NIHSS, higher systolic blood pressure, higher blood creatinine level and D-dimer level are independent risk factors for unfavorable functional outcomes at 90 days after recanalization treatment of large vessel occlusion in patients with acute ischemic stroke.

ABSTRACT

Objective:To investigate the long-term follow-up results and the risk factors of bleeding among very elderly patients with non-valvular atrial fibrillation (NVAF).Methods:A total of 177 patients with NVAF admitted in Beijing Hospital from January 2016 to July 2016 were enrolled in the study, including 107 very elderly patients (aged≥80 years) and 70 elderly patients (aged 65-80 years). The demographic information, comorbid diseases, lifestyles, antithrombotic therapy, thromboembolism risks, bleeding risks, and medical history were documented. Patients were followed up for 5 years and the events of death, thromboembolism, bleeding and major bleeding were recorded.Results:There was no significant difference in the incidence of thromboembolic events between the two groups (15.9%(17/107) vs. 14.3%(10/70), P>0.05). The proportions of bleeding events and severe bleeding events in the very elderly group were higher than those in the elderly group (45.8%(49/107) vs.10.0%(7/70), 14.0%(15/107) vs. 1.4%(1/70), both P<0.05). According to the bleeding events during follow-up, very elderly patients were divided into bleeding group ( n=49) and non-bleeding group ( n=58). Compared with the non-bleeding group, patients in the bleeding group had an older age, a higher proportion of chronic cardiac insufficiency, chronic kidney disease, malignant tumor, bleeding history and higher bleeding risk score (HAS-BLED score) (all P<0.05). Multivariate logistic regression model analysis showed that age, HAS-BLED score, history of bleeding, and complicated malignant tumor were independent risk factors for bleeding events in very elderly patients with NVAF (all P<0.05). Conclusions:Very elderly patients with NVAF have a similar risk of thromboembolism compared with the younger elderly, but have significantly higher risk of the bleeding and major bleeding. Age, HAS-BLED score, bleeding history, and malignant tumor are independent risk factors for bleeding events in very elderly NVAF patients.

ABSTRACT

Objective:To investigate the safety and clinical efficacy of the lateral-rectus approach combined with the Pfannenstiel approach in the treatment of pelvic fractures complicated with urethral rupture.Methods:From January 2013 to June 2021, 20 patients with pelvic fracture complicated with urethral rupture were surgically managed through the lateral-rectus approach and the Pfannenstiel approach at Department of Traumatic Surgery, Center for Orthopaedic Surgery, the Third Hospital Affiliated to Southern Medical University. They were 15 males and 5 females, with an average age of 42 years (from 18 to 55 years). By the Tile classification, there were 11 cases of type B and 9 cases of type C. The first-stage urethral realignment was performed via the Pfannenstiel approach in the supine position after general anesthesia in conjunction with an urologist; at the second-stage, the lateral-rectus approach was used to reduce and fixate the acetabular or pelvic fractures. The operation time, intraoperative blood loss, fracture reduction quality, pelvic functional recovery and complications were documented.Results:In this cohort, the operation time ranged from 80 to 240 min, averaging 140.5 min; the time for simple urethral convergence ranged from 20 to 30 min; the intraoperative blood loss ranged from 400 mL to 2,000 mL, averaging 730 mL. According to the Mears andVelyvis evaluation for fracture reduction quality, anatomical reduction was achieved in 13 cases, satisfactory reduction in 6 cases, and unsatisfactory reduction in one. The 20 patients were followed up for 12 to 68 months (mean, 37 months) after surgery. One fracture got nonunited but the other fractures got united after 3.0 to 4.5 months (mean, 3.5 months). According to the Majeed scoring system, the pelvic function at 12 months after surgery was excellent in 12 cases, good in 6 and fair in 2, giving an excellent and good rate of 90% (18/20). Screw loosening was found in one patient, traction injury to the lumbosacral trunk nerve in another patient, varying degrees of dysuria which responded to periodic urethral dilation in 8 patients, urethral stricture in 3 patients and erectile dysfunction in 5 patients. No abdominal hernia or pelvic infection was observed.Conclusions:The lateral-rectus approach combined with the Pfannenstiel approach can be used effectively to reduce and fixate the pelvic and acetabular fractures, and to repair the urethral rupture in one stage as well. They are also safe due to a low incidence of such complications as abdominal wall hernia and pelvic infection.

ABSTRACT

Objective:To assess the prognostic value of the collateral status and clot burden score based on four-dimensional computed tomography angiography(4D CTA)in anteriorcir culation is chemics troke patients with large ischemic core after endovascular treatment.Methods:Clinical and imaging data of 36 anterior circulation ischemic stroke patients with large infarct core (infarct core≥50.0 ml) after endovascular treatment at our institution from March 2016 to September 2020 were retrospectively reviewed. According to the modified Rankin Scale (mRS) score, patients were divided into the good outcome (mRS score 0-2) and poor outcome (mRS score 3-6) groups. Mann-Whitney U and Fisher tests were used to compare the 4D CTA collateral circulation score, clot burden score, and baseline clinical data between the good and poor outcome groups. Multivariate logistic regression was used to analyze the risk factors associated with the poor outcome (mRS score 3-6) and mortality in patients with large infarct core stroke. Finally, based on the 90-day outcome, a ROC curve was used to obtain the cut-off values for poor prognosis (mRS 3-6) and death, respectively. Results:Ten patients (27.8%) had good outcome and 26 (72.2%) had poor outcome. The patients in the poor outcome group had older median age, higher blood glucose, lower 4D CTA collateral circulation score, lower clot burden score, larger infarct core volume, and higher hemorrhagic transformation and brain hernia (all P<0.05). Multivariate logistic regression showed that the poor collateral circulation score on 4D CTA( OR=0.18, 95% CI: 0.03-0.99, P<0.05)and clot burden score( OR=0.64, 95% CI: 0.44-0.93, P<0.05) were independent predictors of the poor prognosis. The ROC curves revealed that the cut-off value of infarct core for distinguishing between good prognosis and poor prognosis was 63.7 ml, while that for distinguishing between survival and death was 130.3 ml. Conclusions:Endovascular treatment may improve the prognosis of patients with large infarct core of anterior circulation is chemic stroke if the patients have good 4D CTA collateral circulation score and high clot burden score.

ABSTRACT

Objective:To investigate the incidence, neuroimaging features, and related factors for asymptomatic cerebral small vessel disease(CSVD)in the elderly population.Methods:A total of 201 elderly people with no neurological disease history who had undergone brain magnetic resonance imaging(MRI)examination from October 2019 to August 2020 were enrolled.We calculated the total CSVD score for each participant based on lacunar infarcts(LIs), white matter hyperintensities(WMH), enlarged perivascular spaces(EPVS), and cerebral microbleeds(CMBs)(0-4 points).CSVD neuroimaging features and the correlation between CSVD markers and clinical variables were analyzed.Results:In this study, 133 cases(66.2%)showed MRI features consistent with CSVD.Of whom, LIs were present in 44(21.9%), high-grade PVWMH in 88(43.8%), high-grade DWMH in 30(14.9%), basal ganglia EPVS in 61(30.3%), and CMBs in 92(45.8%).Total CSVD burden score( OR=1.876, 95% CI: 1.045-3.364, χ2=4.441, P=0.035), PVWMH( OR=2.821, 95% CI: 1.517-5.244, χ2=10.752, P=0.001), DWMH( OR=2.130, 95% CI: 1.108-4.092, χ2=5.145, P=0.023), and EPVS( OR=3.258, 95% CI: 1.675-6.334, χ2=12.129, P=0.000)were associated with hypertension.Total CSVD burden score, PVWMH, DWMH, EPVS, and CMB were correlated with increasing age( P<0.05).LIs was positively correlated with PVWMH( b=0.231, P=0.001), DWMH( b=0.247, P=0.000)and EPVS( b=0.215, P=0.001).There was a positive relationship between PVWMH and DWMH( b=0.546, P=0.000)as well as EPVS( b=0.388, P=0.000).DWMH was also positively correlated with EPVS( b=0.357, P=0.000)and CMB( b=0.177, P=0.009). Conclusions:The incidence of asymptomatic CSVD is high in the elderly population.The total CSVD score is a useful measure to evaluate asymptomatic cerebral small vessel disease in the elderly population.Neuroimaging features of asymptomatic CSVD are mainly correlated with age and hypertension.

ABSTRACT

Objective:To investigate the clinical effect assistant with pelvic unlocking reduction frame for the treatment of old Denis I or II sacral fractures combined with sacral plexus nerve injury.Methods:From January 2013 to October 2020, 37 patients diagnosed with old sacral fractures with sacral plexus nerve injury which Gibbons classification was grade III were divided into the use group and the non-use group according to whether assisted with pelvic unlocking reduction frame. Eighteen patients (11 males, 7 females, mean age 38±6.4, range from 13-56) were selected into the use group and nineteen patients (14 males, 5 females, mean age 42±10.7, range 19-59) were selected into the non-use group. The three-dimensional (3D) pelvic model (1∶1) was printed before operation. The operation time, intraoperative bleeding, Matta score, visual analogue scale (VAS), Majeed score and gibbons sacral nerve injury grade of the two groups were compared. The healing time and complications of each group was recorded.Results:The average operation time of the use group and the non-use group was 121.0±16.2 min and 182.6±16.2 min, respectively, with significant difference ( t=11.54, P<0.001). The mean operative bleeding was 686±382 ml of the use group and 963±348 ml of the non-use group ( t=2.38, P=0.003). The quality of fracture reduction was evaluated according to Matta scoring standard: the excellent and good rate of the use group was 94% (17/18), and that of the non-use group was 68% (13/19) ( P=0.039). The curative effect was evaluated according to the Majeed score: the use group was 88.72±7.03 points, and that of the non-use group was 72.00±9.75 points ( t=5.96, P<0.001) at 1 year post-operative. One year after operation, the VAS scale of the use group was 0.83±0.71 points, and that of the non-use group was 1.00±0.82 points ( t=0.66, P=0.512). According to Gibbons classification, 15 patients were grade I, 1 patient was grade II and 2 patients were grade III in the use group and 11 patients were grade I, 3 patients were grade II and 5 patients were grade III in the non-use group one year after operation ( Z=-1.04, P=0.401). One patient in the use group presented rupture of plate without symptoms. In the non-use group, 1 case with internal iliac vein rupture which treated with gelatin sponge and no obvious bleeding after operation. 4 cases with unequal length of lower limbs, walking claudication. The complication rate of the use group was 6% (1/18), and that of the non-use group was 26% (5/19) ( P=0.042) . Conclusion:The lateral rectus abdominis approach combined with pelvic unlocking reduction frame can reduce the operation time and bleeding, improve the fracture reduction in the treatment of old Denis type I and II sacral fractures with sacral plexus injury.

ABSTRACT

Objective:To investigate the application of three-dimensional (3D) image fusion technique of pelvic enhanced CT and magnetic resonance neurography (MRN) on the patients of pelvic fractures with lumbosacral plexus injury.Methods:From January 2019 to December 2020, 15 patients (11 males, 4 females, mean age 26.67±11.34 of pelvic fracture (AO classification C1.3 of 11 cases, C2 of 2 cases, C3 of 2 cases) with lumbosacral plexus injury underwent 3D image fusion of pelvic enhanced CT and MRN. All patients exhibited lower limb nerve dysfunction after injury. The preoperative muscle strength were evaluated by British Medical Research Council (BMRC) criteria: grade 0 in 2 cases, grade 1 in 5, grade 2 in 7 and grade 3 in 1. Physical examination and enhanced CT combined with MRN 3D image fusion technology were used to accurately determine the injury site of lumbosacral plexus nerve, fracture displacement, and the direction of blood vessels and ureters, and develop corresponding surgical plans. The neurological functions were measured in post-operation follow-up.Results:All 15 operations were successfully completed and the site of lumbosacral plexus injury during operation was consistent with preoperative fusion image, and inconsistency of injury characteristic in 4 patients (4/15, 27%). Among the 6 cases of laparoscopic surgery, 2 cases were changed to open surgery because of the difficulty of nerve decompression. The average time of 4 cases of laparoscopic surgery was 116.27±26.46 min and intraoperative blood loss was 102.50±79.32 ml. The average time of 11 cases of open operation was 123.64±38.28 min, and intraoperative blood loss was 713.64±393.12 ml. For the opening operations, 9 cases were successfully decompressed, and nerve disruption was observed in 2 patients. All 15 patients were followed up. The average follow-up time was 9.33±2.19 months. The radial bony healing was observed in each case at the end of follow-up, mean healing time was 5.03±1.04 months (range, 3-6 months). In addition, patients' muscle strength recovered, 8 cases of grade 5, 3 cases of grade 4, 1 case of grade 3, 1 case of grade 2, and 2 cases of grade 0 after surgery. The difference was statistically significant ( Z=3.27, P<0.001). On the other hand, in sensory function assessment, there were 8 cases of grade S5, 1 case of grade S4, 3 cases of grade S3, 1 case of grade S2 and 2 cases of grade S0 after surgery. Conclusion:3D image fusion of enhanced CT and MRN can accurately locate and characterize pelvic fractures combined with lumbosacral plexus injury before surgery, accurately guide the formulation of surgical plan, and reduce surgical trauma and related complications.

ABSTRACT

Objective:To establish the classification system of sacroiliac joint dislocation with ipsilateral sacral wing fracture (SJDISWF), examine its reliability and evaluate the clinical application.Methods:A multi-center retrospective case series study was conducted to analyze the clinical data of 20 SJDISWF patients admitted to Third Affiliated Hospital of Southern Medical University, Honghui Hospital Affiliated to Xi′an Jiaotong University and Third Hospital of Hebei Medical University from January 2016 to December 2019. There were 8 males and 12 females, aged from 13-58 years[(34.7±13.2)years]. Based on the direction of sacral displacement, SJDISWF was divided into 3 types. Type I: the sacroiliac joint dislocated and the ipsilateral sacral wing fracture fragment was anteriorly prolapsed; Type II: the sacroiliac joint dislocated, the ipsilateral sacral wing fracture fragment was compressed or crushed, the anterior sacral foramen may fractured; Type III: the sacroiliac joint dislocated and the ipsilateral sacral wing fracture end was inserted into the sacral canal, causing an intra-sacral canal occupation. The reliability of the classification was performed based on the assessment results of two phases in four observers at 4-week intervals. Treatments were utilized based on the types I, II, III fractures, including anterior approach for open reduction and internal fixation, closed reduction and internal fixation or posterior approach for open reduction and internal fixation respectively. Postoperative fracture healing time was recorded. Quality of fracture reduction was graded according to Matta′s criteria. Majeed functional score was recorded at postoperative 3 months, 6 months and the final follow-up. Complications were detected as well.Results:The overall Kappa value of inter-observer reliability was 0.890. The overall Kappa value of intra-observer reliability was 0.854. There were 12 patients with type I, 7 with type II and 1 with type III. All patients went through the procedure uneventfully and were followed up for 6-36 months[(20.0±8.7)months]. All patients achieved clinical healing in 8-14 weeks[(10.2±1.7)weeks]. According to the Matta′s criteria for fracture reduction, the outcome was excellent or good in 83% (10/12) for type I, 71% (5/7) for type II and 0% (0/1) for type III, with the overall excellent rate of 75%. Majeed functional score was (74.6±5.2)points at postoperative 3 months and (84.4±5.8)points at postoperative 6 months ( P<0.01). According to Majeed functional score, the outcome was excellent or good in 75% (9/12) for type I, 100% (7/7) for type II and 0% (0/1) for type III at the final follow-up, with the overall excellent rate of 80%. There were no complications such as lateral femoral cutaneous nerve or sciatic nerve injury, lower extremity deep vein thrombosis, sacroiliac joint pain, failure of internal fixation or loss of fracture reduction during the follow-up. Conclusions:The SJDISWF classification has high reliability. The classification-oriented treatment strategy has achieved a relatively satisfactory restoration and functional recovery, indicating that the classification plays a certain role in guiding treatment selection for SJDISWF.

ABSTRACT

Objective:To compare the clinical efficacy of lateral-rectus approach and ilioinguinal approach in the treatment of Torode-Zieg type IV pelvic fracture in toddlers.Methods:A retrospective cohort study was used to analyze the clinical data of 12 toddlers with Torode-Zieg type IV pelvic fracture admitted to Affiliated Hospital of Youjiang Medical College for Nationalities and Third Affiliated Hospital of Southern Medical University from June 2012 to June 2019. There were 6 males and 6 females, aged 13-36 months [(23.9±7.4)months]. Treatment via ilioinguinal approach was performed for 5 patients (ilioinguinal group), and via lateral-rectus approach for 7 patients (lateral-rectus group). Operation duration, intraoperative blood loss and postoperative complications were compared between the two groups. At the last follow-up, pelvic function was evaluated by Majeed function score, and fracture reduction was evaluated according to Mears-Velyvis radiological evaluation criterion.Results:All patients were followed for 24-72 months [(46.0±18.5)months]. In ilioinguinal group and lateral-rectus group, the operation time was (295.0±95.3)minutes and (165.1±52.2)minutes, respectively ( P<0.05), and the intraoperative blood loss was (190.0±65.2)ml and (225.7±92.0)ml, respectively ( P>0.05). In ilioinguinal group, the development of bilateral iliac wings was asymmetric in 3 patients. In lateral-rectus group, fracture-dislocation of epiphyseal plate together with abnormal development of iliac wing occurred in 1 patient, but had no effects on the function of lower limbs. According to Majeed function score at the last follow-up, the pelvic function in ilioinguinal approach group was rated as excellent in 1 patient, good in 2, fair in 1 and poor in 1, with the excellent and good rate of 60%, while the pelvic function in lateral-rectus group was excellent in 4 patients, good in 1, fair in 2 and poor in none, with the excellent and good rate of 71% ( P>0.05). According to Mears-Velyvis radiological evaluation criterion at the last follow-up, the fracture reduction in ilioinguinal group was rated as satisfied in 3 patients and dissatisfied in 2 patients, with the satisfaction rate of 60%, while the fracture reduction in lateral-rectus group was satisfied in 7 patients and dissatisfied in none, with the satisfaction rate of 100% ( P>0.05). Conclusions:For Torode-Zieg type IV pelvic fracture in toddles, both surgical approaches can complete the reduction and fixation. However, the lateral-rectus approach has shorter operation time and less damage to the epiphyseal structure around the pelvis than the ilioinguinal approach.

ABSTRACT

Objective:To investigate the clinical efficacy of integrated acetabular wing-plate in the management of both column fractures with posterior wall involvement via the lateral-rectus approach.Methods:A retrospective case series analysis was performed on 43 patients with both column fractures involved with posterior wall admitted to Third Affiliated Hospital of Southern Medical University from March 2016 to June 2020. There were 35 males and 8 females, aged 19-78 years [(47.3±13.3)years]. The single lateral-rectus approach was used to expose, reduce and fix the fracture using the integrated acetabular wing-plate. Operation time, incision length, intraoperative blood loss and bone healing time were recorded. Quality of fracture reduction was assessed according to the Matta reduction criteria at postoperative 2 days, and hip function by the modified Merle d′Aubigné-Postel score at postoperative 3 months and 12 months. Postoperative complications were observed.Results:All patients were followed up for 12-48 months [(28.1±13.1)months]. Operation duration was 35-150 minutes [(84.6±26.3)minutes], with incision length of 8-12 cm [(9.4±1.0)cm] and intraoperative blood loss of 100-1 200 ml [(200(300, 500) ml]. Bone healing time was 3-6 months [(3.9±0.9)months]. According to Matta reduction criteria,the results were excellent in 32 patients, good in 7 and poor in 4 at postoperative 2 days, with the excellent and good rate of 91%. The modified Merle d′Aubigné-Postel score was 12-18 points [(16.1±1.5)points] at postoperative 3 months, and 13-18 points [(17.3±1.2)points] at postoperative 12 months ( P<0.01). According to modified Merle d′Aubigné-Postel score, the results were excellent in 3 patients, good in 34 and fair in 6 at postoperative 3 months, with the excellent and good rate of 86%; and the results were excellent in 32 patients, good in 9 and fair in 2 at postoperative 12 months, with the excellent and good rate of 95% ( P<0.01). Postoperative complications were incision fat liquefaction and infection in 1 patient, weakness of hip adduction in 5 and screw loosening with traumatic arthritis in 1. There was no sciatic nerve injury or heterotopic ossification. Conclusion:For both column fractures with posterior wall involvement, single lateral-rectus approach combined with integrated acetabular wing-plate has advantages of short operation time, minor trauma, low rate of bleeding and complications, and good hip function recovery, indicating satisfactory clinical effect.

ABSTRACT

Objective:To investigate the relationship between cerebral small vessel disease and thyroid hormones in the elderly.Methods:A total of 314 subjects aged ≥60 years with records of head magnetic resonance image(MRI), serum thyroid function tests and physical examinations collected in the Department of Health Care Neurology of Beijing Hospital from May 2019 to November 2020 were consecutively included for this cross-sectional study.Participants were assigned into the cerebral small vessel disease group if their head MRI presentations met the following standards: the Fazekas score ≥3 points; the Fazekas score ≥2 points, with 1 cavity; new subcortical infarcts; or cerebral microhemorrhage.Differences in thyroid function were compared between the cerebrovascular disease group(n=129)and the group without cerebrovascular disease(control group, n=185).Results:A total of 314 subjects were enrolled, of whom 129 met the head MRI standards for cerebrovascular disease, and 185 who did not meet the standards entered the control group.Comparison of thyroid function found a statistically significant difference in FT3( t=3.270, P=0.001)between the two groups.As for the association of a specific type of cerebral small vessel disease with thyroid function, there was a statistically significant difference in the FT3 level between the lacunar infarction group and the non-lacunar infarction group( t=3.106, P=0.002)and between the cerebral microhemorrhage group and the non-cerebral microhemorrhage group( t=2.125, P=0.034). Groups with different Fazekas scores in white matter hyperintensity showed statistically significant differences in rT3( F=3.092, P=0.027), FT3( F=5.427, P=0.001)and FT4( F=2.646, P=0.049). After correction for hyperlipidemia, rT3 and FT4, it was found that age( OR=1.044, 95% CI: 1.022-1.067, P=0.000), hypertension( OR=0.533, 95% CI: 0.294-0.963, P=0.037)and FT3( OR=0.276, 95% CI: 0.159-0.478, P=0.000)were related to cerebral small vessel disease. Conclusions:FT3 levels at the lower end of the normal range are associated with cerebral small vessel disease in the elderly.

ABSTRACT

Objective:To explore the surgical technique and clinical results of the lateral-rectus approach (LRA) for acetabular fractures combined with ipsilateral greater sciatic notch fractures.Methods:Nine cases of acetabular fractures combined with ipsilateral greater sciatic notch fractures treated by the LRA from January 2015 to January 2021 were involved in this study, including 7 males and 2 females with age of 39.8±15.4 years (range, 25-54 years). Six cases were injured by falling and the others by traffic accidents. There were 3 cases combined with pelvic fractures, 1 combined with craniocerebral injury, 3 combined with thoracic injury, 2 combined with closed abdominal injury, and 3 combined with other fractures of the extremities. Based on the Letournel-Judet classification, the cases were all classified as double-column acetabular fractures. The fractures of the greater sciatic notch are all fractures with obvious displacement from the lower part of the sacroiliac joint through the top of the greater sciatic notch to the posterior column of the acetabulum. Pelvic X-ray and CT examination were performed after operation. The reduction quality of the acetabulum and greater sciatic foramen was evaluated by Matta's criteria. The function of the hip joint was assessed by modified Merle D'Aubigné-Postel score.Results:All 9 patients were successfully completed the operation, and followed up. The operation time was 140.4±55.2 min (range, 110-190 min). The amount of intraoperative blood loss was 770.5±430.9 ml (range, 540-1,260 ml). All cases of fractures had healed in 7.7±3.4 weeks (range, 6-12 weeks) after operation. According to Matta's reduction quality criteria, the quality of fracture reduction after surgery was excellent in 7 cases and good in 2 cases. The follow-up period was 24.8±8.8 months (range, 6-12 months). Fractures of the acetabulum and greater sciatic foramen healed well, with the healing time of 6 to 12 weeks. There were no complications such as loss of fracture reduction, failure of internal fixation, traumatic arthritis or necrosis of femoral head. Matta's modified Merle d'Aubigne-Postel hip function score was 16.2±0.6 (range, 12-18) one year after surgery. There were excellent in 6 cases, good in 2 cases, fair in 1 case, with an excellent and good rate of 89%.Conclusion:Fractures of the acetabulum and ipsilateral greater sciatic notch are serious injuries with difficulty in surgical reduction and fixation. The LRA can better complete reduction and fixation of the above fractures, obtaining satisfactory clinical outcomes.

ABSTRACT

Objective:To study the correlation between the acute-phase characteristics of motor evoked potential (MEP) and severities of spinal cord injury in patients with acute cervical hyperextension injury and central cord syndrome (CCS).Methods:Retrospectively analyzed were the data of 45 patients with acute cervical hyperextension injury and CCS (observation group) who had been admitted to Department of Orthopedics, Tongji Hospital Affiliated to Tongji University from December 2018 to July 2021 and 20 healthy controls. Examination of transcranial magnetic stimulation-induced MEP was performed in patients with CCS and healthy controls using a magpro x100 magnetic stimulator, and recording was conducted in bilateral abductor pollicis brevis (APB). The characteristics of MEP waveform latency, amplitude and motor threshold were described and compared between the healthy control and observation groups; the correlations were analyzed between the MEP latency and the severity of spinal cord injury [American Spinal Injury Association (ASIA) total score and motor function of Upper Extremity Motor Subscores (UEMS)] in the observation group. According to different MEP-induced states, the patients in the observation group were divided into a resting group ( n=19), a facilitation group ( n=18), and a no-waveform group ( n=8). The severity of spinal cord injury (ASIA total score) and the functional independence of the spinal cord (SCIM-Ⅲ score) were compared among the 3 groups to analyze the correlation between the MEP-induced state and the severity of spinal cord injury (ASIA total score). Results:The observation group had a significantly longer MEP latency [(30.16±6.32) ms], a significantly smaller amplitude [(0.54±0.30) mV] and a significantly higher motor threshold [(65%±11%)] than the healthy control group (all P<0.05). The MEP latency in the observation group was significantly correlated with ASIA total score ( r=-0.730, P<0.001) and UEMS ( r=-0.740, P<0.001). The ASIA total score and SCIM-Ⅲ score were significantly different among the 3 groups ( P<0.05), and the MEP-induced state was significantly correlated with the severity of spinal cord injury (ASIA total score) ( r=0.668, P<0.001). Conclusions:In patients with acute cervical hyperextension injury and CCS, the MEP latency is prolonged, the amplitude lowered, and the motor threshold enhanced. The MEP latency is strongly correlated with the severity of spinal cord injury and upper limb motor function. The MEP-induced state is also closely related to the severity of spinal cord injury.

ABSTRACT

Objective:To investigate the surgical techniques and clinical efficacy of periacetabular osteotomy through the lateral-rectus approach (LRA) for obsolete acetabular fractures.Methods:The 22 patients with old acetabular fracture were retrospectively analyzed who had been admitted to Department of Traumatic Surgery, The Third Affiliated Hospital to Southern Medical University from June 2012 to June 2019. They were 16 males and 6 females, aged from 22 to 61 years (average, 45.0 years). By the Judet-letournel classification, there were 4 anterior + posterior hemitransverse fractures, 2 T-shaped fractures and 16 both column fractures. The time from injury to surgery was 3 to 12 weeks in 15 cases, 3 to 6 months in 5 cases, 9 months in one case, and 3 years in one case. After the whole acetabulum was exposed outside the peritoneum through LRA in all patients, periacetabular osteotomy was conducted under direct vision, followed by fixation with multiple reconstruction plates or integrated acetabular airfoil anatomical plates after reduction. Recorded were the operation time, intraoperative blood loss, fracture reduction quality, affected hip function and complications in the patients.Results:In this cohort the operation time ranged from 110 to 205 min, averaging 140.5 min; intraoperative blood loss ranged from 500 to 2,100 mL, averaging 1,250.4 mL. According to the Matta X-ray criteria, the postoperative reduction was assessed as excellent in 7 cases, as good in 11 and as poor in 4, yielding an excellent and good rate of 81.8% (18/22). All the 22 patients were followed up for 12 to 36 months (mean, 22.1 months) and achieved fracture union. The one-year follow-up showed that their modified Merle d'Aubigné & Postel scores ranged from 6 to 18 points, averaging 14.6 points and giving 6 excellent, 10 good, 3 fair and 2 poor cases [an excellent and good rate of 72.7% (16/22)]. Osteonecrosis of the femoral head developed in 2 patients one of whom underwent total hip replacement.Conclusions:As LRA can expose the entire hemipelic ring from the medial side of the pelvis, the periacetabular osteotomy can be performed and the fractures of anterior or posterior column and the quadrilateral area can be reduced under direct vision through the medial side of the acetabulum. Moreover, ideal results can be achieved with the use of multiple reconstruction plates or integrated acetabular airfoil anatomical plates.

ABSTRACT

Objective:To investigate the surgical technique and the clinical effects of direct posterior approach (DPA) with the fixation of percutaneous tunnel screw and plate for acetabular posterior comminuted fractures.Methods:Thirty-six cases with acetabular posterior comminuted fractures treated by this technique from January 2016 to July 2020 were retrospectively analyzed in this study. There were 28 males and 8 female, aged 42.0±12.1 (range 19-64) years. According to Letournel-Judet classification, there were 28 cases of transverse associated with posterior wall fractures, 6 cases of posterior column with posterior wall fractures and 2 cases of T shape with posterior wall fractures. DPA was adopted in prone position. The anterior and posterior column fractures of the acetabulum were reduced under direct vision and then fixed with percutaneous tunnel screw. Further, the posterior wall fractures of the acetabulum were reduced and fixed with plate and screws. The operation duration, intraoperative blood loss, incision length, fracture union time, fracture reduction quality, postoperative complications and hip function were recorded.Results:The incision was 9.8±1.2 (range 8-12) cm. The operation duration was 102.9±21.4 (range 65-145) min. Intraoperative bleeding was 214.0±116.9 (range 100-640) ml. Postoperative X-ray and CT examinations showed perfect reduction. All the patients were followed up for 20.9±9.2 (range 10-38) months. The fracture healing time was 4.6±1.0 (range 3-6) months. There was no patient with damaged superior gluteal nerve and blood vessel. There were 2 cases of femoral head cystic changes without pain in walking, 1 case of postoperative infection and bacteremia who was cured at 1 month after debridement and anti-infection treatment, 1 case of sciatic nerve injury but recovered at 3 months after operation, and 1 case of heterotopic ossification at 3 months after surgery without affecting hip motion. According to the Matta's criteria, the reduction quality of the acetabular fracture was rated as excellent in 28 cases, good in 6 cases, fair in 2 cases. According to the modified Merle D'Aubigné and Postel scoring system, hip joint function was excellent in 24 cases, good in 10 cases and fair in 2 cases.Conclusion:DPA approach can directly reduce acetabular posterior comminuted fractures through a minimal incision. Combined with the technique of percutaneous tunnel screw, it displays great advantages of less trauma and with good clinical effects.

ABSTRACT

Objective:To study the use of trans gastric sinus stent placement and drainage in management of persistent external pancreatic fistula.Methods:The clinical data of 12 patients who developed persistent external pancreatic fistulae after severe acute pancreatitis, pancreatic trauma or pancreatic surgery who were treated at the First Medical Center of Chinese PLA General Hospital from August 2018 to December 2020 were retrospectively analyzed. There were 10 males and 2 females, aged 30 to 65 years, median 43.5 years. These patients underwent trans gastric sinus stent placement and drainage, and were followed-up to study persistence of pancreatic fistula, new pancreatic fluid accumulation, complications and death.Results:In this study, there were 9 patients who developed persistent external pancreatic fistulae after severe acute pancreatitis, 2 patients after pancreatic trauma, and 1 patient after pancreatic surgery. The median operation time was 47 min (range 38-54 min). The technical success rate was 100.0% (12/12). The median follow-up was 22.5 months (range 2-29 months). Seven days after stenting, the percutaneous drainage tubes (urinary catheters) of all the patients were removed. One patient (8.3%) developed recurrence of pancreatic fistula 17 days after treatment. The same procedure of placing another stent was done and the patient recovered. Six months after treatment, 2 patients (16.7%) lost their stents, and 1 patient developed a pseudocyst (recurrence of pancreatic fistula). The maximum diameter of this pseudocyst increased gradually to 7cm after 9 months. A double pigtail drainage tube was placed under endoscopy in this patient, and the patients recovered. All the other patients did not develop recurrence of pancreatic fistula or pseudocyst. During the follow-up period, no patient developed any new complications including pancreatic fluid accumulation, fever, bleeding, infection and organ dysfunction, and no patients died.Conclusion:It was safe and efficacious to use trans gastric sinus stent placement for treatment of persistent external pancreatic fistula. However, the long-term outcomes require further studies.
