RESUMEN
BACKGROUND:Stage Ⅲ Kümmell's disease is characterized by a high degree of vertebral compression and posterior wall defects.Most of the patients are elderly people with severe osteoporosis and various medical diseases.Clinically,some surgical methods are often at high risk and are controversial. OBJECTIVE:To investigate the clinical efficacy of screw placement combined with transpedicular impaction bone grafting in the treatment of stage Ⅲ Kümmell's disease. METHODS:The clinical data of injured vertebral screw placement combined with transpedicular impaction bone grafting in treatment of stage Ⅲ Kummell's disease from May 2016 to August 2021 were retrospectively analyzed.Visual analog scale score,Oswestry disability index,anterior vertebral heights,kyphotic Cobb angle and American Spinal Injury Association(ASIA)impairment scale were used to evaluate the effects of surgery.The operation time,intraoperative blood loss and complications were recorded.CT scans were used to evaluate the healing of injured vertebrae at the final follow-up visit. RESULTS AND CONCLUSION:(1)A total of 26 patients were included,with 7 males and 19 females,at the age range of 62-81 years[mean(69.7±4.8)years].The follow-up time was 18-60 months[mean(35.1±8.9)months].The average operative duration was 133.5 minutes(100-165 minutes),and the average intraoperative blood loss was 285.3 mL(210-350 mL).(2)Visual analog scale and Oswestry disability index scores 1 week after surgery were significantly lower than those before surgery.(3)At 1 week after surgery,the anterior vertebral height corrections and the Cobb angle were(9.0±0.7)mm and(16.2±1.0)°,respectively.During the follow-up period,the loss of vertebral height and kyphosis correction were(5.1±0.3)mm and(8.0±0.4)°,respectively.(4)14 patients(54%)had ASIA grade D before operation,which recovered to grade E at the last follow-up.CT scan showed that all patients achieved good osseous union.(5)Complications occurred in seven patients(27%),including hypostatic pneumonia in two cases,postoperative superficial wound tissue liquefaction in two cases,and adjacent vertebral compression fractures in three cases.(6)It is concluded that screw placement of the injured vertebra combined with transpedicular impaction bone grafting can rapidly rebuild spinal stability,effectively relieve pain and improve neurological function in the treatment of stage Ⅲ Kümmell's disease.This technique is an effective and relatively minimally invasive surgical option.
RESUMEN
Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.
RESUMEN
Objective:To explore the efficacy of stage I modified posterior vertebral column resection (mPVCR) in the treatment of postoperative infection after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective case series study was conducted to analyze the clinical data of 11 OVCF patients with post-PVP infection who were admitted to Zhengzhou Orthopedics Hospital from January 2016 to June 2022, including 4 males and 7 females, aged 61-81 years [(70.2±6.4)years]. Injured segments included T 9 in 1 patient, T 11 in 2, T 12 in 3, L 1 in 1, L 2 in 2, T 11-T 12 in 1, and T 12-L 1 in 1. American Spinal Injury Association (ASIA) grading was grade D in 5 patients and grade E in 6. All the patients were treated with stage I mPVCR. The operation time and intraoperative bleeding volume were recorded. The values of Visual Analogue Scale (VAS), Oswestry Dysfunction Index (ODI), and Cobb angle of the lesion segments before, at 2 weeks, 3 months after surgery, and at the last follow-up were compared. The loss of Cobb angle of the lesion segments at 2 weeks after surgery and at the last follow-up were compared, and the ASIA grading at the last follow-up was recorded. The infection control, bone healing, and the incidence of complications were observed at the last follow-up. Results:All the patients were followed up for 12-44 months [(26.0±9.4)months]. The operation time and intraoperative bleeding volume were 230-330 minutes [(279.2±28.6)minutes] and 500-1 100 ml [(840.9±184.1)ml] respectively. At 2 weeks, 3 months after surgery and at the last follow-up, the VAS scores were (4.0±0.8)points, (2.7±0.9)points, and (2.4±0.7)points respectively, which were all lower than that before surgery [(8.1±1.2)points] ( P<0.01); the ODI was (45.5±5.1)%, (30.0±6.5)%, and (18.5±3.6)% respectively, which were all lower than that before surgery [(78.7±6.2)%] ( P<0.01); the Cobb angle of the lesion segments were (7.9±1.4)°, (8.5±1.4)°, and (9.2±1.5)° respectively, which were lower than that before surgery [(25.5±9.2)°] ( P<0.01). The VAS and ODI were both improved at 3 months after surgery compared with those at 2 weeks after surgery ( P<0.05), while there was no significant difference in Cobb angle of the lesion segments ( P>0.05). The ODI was further improved at the last follow-up compared with that at 3 months after surgery ( P<0.05), while there were no significant differences in VAS or Cobb angle of the lesion segments ( P>0.05). The loss of Cobb angle correction of the lesion segment at the last follow-up was 0.96 (0.69, 1.45)° compared with that at 2 weeks after surgery and the rate of loss of Cobb angle correction of the lesion segment was 4.4(2.2, 7.4)%. At the last follow-up, the ASIA grading was grade E for all the patients, who were able to walk normally independently. The infection was all cured and good bony fusion was observed in the operated area at the last follow-up. Two patients had pleural effusion and pulmonary atelectasis, 1 incision fat liquefaction, and 1 pneumonia after the surgery. None of the patients had internal fixation failure and serious complications such as worsening neurological symptoms or death. Conclusion:Stage I mPVCR for the treatment of post-PVP infection in patients with OVCF is proved to attain significant pain relief and functional improvement, good correction results, effective reconstruction of spinal stability, complete removal of infected lesions, and few serious complications.
RESUMEN
Objective:To investigate the efficacy of one-stage posterior-anterior combined operation for the treatment of abnormal fusion after facet joint dislocation in the subaxial cervical spine.Methods:A retrospective study of case series was conducted to analyze the clinical data of 10 patients with abnormal fusion after facet joint dislocation in the subaxial cervical spine who had been admitted to Department of Spine Surgery, Zhengzhou Orthopedic Hospital from January 2015 to May 2023. There were 7 males and 3 females with an age of (41.2±3.1) years. Preoperative American Spinal Injury Association (ASIA) grading: 5 cases of grade A, 4 cases of grade B, and 1 cases of grade C. All the patients were treated with one-stage posterior-anterior combined operation. The surgical time and intraoperative bleeding volume were recorded. The ASIA grading was used to evaluate the improvements in nerve function of the spinal cord 3 months after surgery. The VAS scores, cervical intervertebral heights, and Cobb angles were compared between pre-surgery, 3 months after surgery, and the last follow-up. The fusion of intervertebral bone graft was evaluated 3 months after surgery using the Bridgell intervertebral fusion criteria. Complications were observed.Results:All patients were followed up for 15.5 (13.8, 20.5) months. The surgical time was (119.5±3.6) minutes, and the intraoperative bleeding volume (141.6±25.6) mL. Significant improvements in VAS score, cervical intervertebral height, and Cobb angle were observed at 3 months after surgery and the last follow-up compared with the pre-surgery values ( P<0.05), but there was no statistically significant difference between 3 months after surgery and the last follow-up ( P>0.05). ASIA grading 3 months after surgery: 4 cases of grade A, 4 cases of grade B, and 2 cases of grade C. By the Bridgell intervertebral fusion criteria at 3 months after surgery: 9 cases of grade Ⅰ and 1 cases of grade Ⅱ, showing good intervertebral fusion. Surgery went on well for all patients, showing no postoperative complications such as aggravation of nerve lesion or vascular injury. Conclusion:In the treatment of abnormal fusion after facet joint dislocation in the subaxial cervical spine, the efficacy of one-stage posterior-anterior combined operation is definite because it can effectively reduce pain, restore the height and physiological curvature of the cervical intervertebral space, and achieve good intervertebral fusion.
RESUMEN
ObjectiveTo retrospectively analyze the clinical efficacy of Xibining Ⅱ prescription in the treatment of knee osteoarthritis with cold-dampness blockage syndrome by oral medication and to explore the influencing factors of endpoint events. MethodA real-world retrospective cohort design was adopted， and medical records of knee osteoarthritis patients with cold-dampness blockage syndrome treated with oral medication from the orthopedics outpatient department of Jiangsu Province Hospital of Chinese Medicine were collected. All patients received conventional Western medicine treatment and were divided into non-exposure group （573 cases） and exposure group （427 cases） according to whether or not they received treatment with Xibining Ⅱ prescription. Descriptive analysis of the baseline data of the 1 000 screened cases was performed using IBM SPSS 27.0. According to the baseline data， 334 pairs were matched using the propensity score matching method， resulting in a total of 668 cases in both groups. The changes in visual analogous scale （VAS）， Western Ontario and McMaster Universities Osteoarthritis Index （WOMAC） total score， Japanese Knee Osteoarthritis Measure （JKOM） score， and traditional Chinese medicine （TCM） syndrome score before treatment and at 2， 6， 12 weeks after treatment， as well as the incidence of adverse reactions， were compared between the two groups. A multivariate logistic regression analysis was conducted to analyze the influencing factors of endpoint events， with clinical cure judged based on the improvement rate of WOMAC total score before and after treatment. ResultAfter 12 weeks of treatment， compared to the results before treatment， the VAS， WOMAC total score， JKOM score， and TCM syndrome score of patients in both groups significantly decreased （P<0.01）. Compared to the non-exposure group， the exposure group showed a more significant reduction in VAS， WOMAC total score， JKOM score， and TCM syndrome score （P<0.01）. After 12 weeks of treatment， the clinical cure rate and significant efficiency were higher in the exposure group than in the non-exposure group （P<0.05）. Compared to the results before treatment within each group， VAS， WOMAC pain， stiffness， function scores， JKOM score， and TCM syndrome score significantly decreased at 2， 6， 12 weeks after treatment in both groups （P<0.01）. Compared to the non-exposure group at the same time points， the exposure group showed a reduction in VAS at 2， 12 weeks， WOMAC pain at 6， 12 weeks， and function scores at 12 weeks （P<0.05， P<0.01）. The JKOM score decreased at 6， 12 weeks， and the TCM syndrome score significantly decreased at 2， 6， 12 weeks in the exposure group （P<0.05， P<0.01）. Multivariate logistic regression analysis at 12 weeks showed that factors affecting clinical cure included the course of disease， history of alcohol consumption， hypertension， coronary heart disease， and the use of Xibining Ⅱ prescription （P<0.05， P<0.01）. Compared to the non-exposure group at the same time points， the incidence of epigastric discomfort in the exposure group was lower at 2， 12 weeks （P<0.01）， the incidence of diarrhea and vomiting was slightly higher than that in the non-exposure group， but the difference was not statistically significant. ConclusionThe clinical application of Xibining Ⅱ prescription combined with conventional Western medicine treatment in the treatment of knee osteoarthritis with cold-dampness blockage syndrome is more effective than conventional Western medicine treatment alone. It can significantly reduce VAS， WOMAC total score， JKOM score， and TCM syndrome score， with more pronounced long-term effects and a low incidence of adverse reactions.
RESUMEN
SUMMARY OBJECTIVE: The objective of this study was to explore the relationship between serum soluble fms-like tyrosine kinase 1 and the severity of acute pancreatitis and its diagnostic utility. METHODS: This study was carried out by searching Chinese and English literature from the establishment of the database to July 9, 2023, systematically, and assessing the quality and heterogeneity of the articles included. RESULTS: Thirteen studies with a total of 986 patients were included. Patients with severe acute pancreatitis showed higher levels of soluble fms-like tyrosine kinase 1 compared with mild acute pancreatitis [weighted mean difference=76.64 pg/mL, 95% confidence interval (95%CI 50.39-102.89, p<0.001)]. Soluble fms-like tyrosine kinase 1 predicted pooled sensitivity, specificity, and area under the curve were 79%, 74%, and 0.85 for severe acute pancreatitis, with some heterogeneity (I2>50% or p<0.05). In the subgroup analysis, cutoff >150 pg/mL was found to be a heterogeneous factor. CONCLUSION: Soluble fms-like tyrosine kinase 1 is a reliable tool for identifying acute pancreatitis severity, but only as a screening tool.
RESUMEN
Ankylosing spondylitis (AS) combined with spinal fractures with thoracic and lumbar fracture as the most common type shows characteristics of unstable fracture, high incidence of nerve injury, high mortality and high disability rate. The diagnosis may be missed because it is mostly caused by low-energy injury, when spinal rigidity and osteoporosis have a great impact on the accuracy of imaging examination. At the same time, the treatment choices are controversial, with no relevant specifications. Non-operative treatments can easily lead to bone nonunion, pseudoarthrosis and delayed nerve injury, while surgeries may be failed due to internal fixation failure. At present, there are no evidence-based guidelines for the diagnosis and treatment of AS combined with thoracic and lumbar fracture. In this context, the Spinal Trauma Academic Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate the Clinical guideline for the diagnosis and treatment of adult ankylosing spondylitis combined with thoracolumbar fracture ( version 2023) by following the principles of evidence-based medicine and systematically review related literatures. Ten recommendations on the diagnosis, imaging evaluation, classification and treatment of AS combined with thoracic and lumbar fracture were put forward, aiming to standardize the clinical diagnosis and treatment of such disorder.
RESUMEN
Objective:To investigate the efficacy of the classified reduction based on CT two-dimensional images for the surgical treatment of single segment facet joint dislocation in subaxial cervical spine.Methods:A retrospective case series study was made on 105 patients with single segment facet joint dislocation in subaxial cervical spine admitted to Zhengzhou Orthopedic Hospital from January 2015 to October 2022. There were 63 males and 42 females, with the age range of 22-78 years [(47.5±3.6)years]. Preoperative American Spinal Cord Injury Association (ASIA) classification was grade A in 23 patients, grade B in 45, grade C in 22, grade D in 15 and grade E in 0. The classification of surgical approach was based on the presence or not of continuity between anterior and posterior subaxial cervical structures and the movability of the posterior cervical facet joint on CT two-dimensional images, including anterior cervical surgery if both were presented and posterior facet joint resection plus anterior cervical surgery if there was discontinuity between anterior and posterior subaxial cervical structures or posterior facet joint fusion. Reduction procedures were applied in accordance with the type of facet joint dislocation classified based on the position of the lower upper corner of facet joint, including skull traction or manipulative reduction for the dislocation locating at the dorsal side (type A), intraoperative skull traction and leverage technique for the dislocation locating at the top (type B) and intraoperative skull traction and leverage technique with boosting for the dislocation locating at the ventral side (type C). If the dislocation of two facet joints in the same patient was different, the priority of management followed the order of type C, type B and type A. The reduction success rate, operation time and intraoperative blood loss were recorded. The cervical physiological curvature was evaluated by comparing the intervertebral space height and Cobb angle before operation, at 3 months after operation and at the last follow-up. The fusion rate of intervertebral bone grafting was evaluated by Lenke grading at 3 months after operation. The spinal cord nerve injury was assessed with ASIA classification before operation and at 3 months after operation. Japanese Orthopedic Association (JOA) score was applied to measure the degree of cervical spinal cord dysfunction before operation and at 3 months after operation, and the final follow-up score was used to calculate the rate of spinal cord functional recovery. The occurrence of complications was observed.Results:All patients were followed up for 3-9 months [(6.0±2.5)months]. The reduction success rate was 100%. The operation time was 40-95 minutes [(58.6±9.3)minutes]. The intraoperative blood loss was 40 to 120 ml [(55.7±6.8)ml]. The intervertebral space height was (4.7±0.3)mm and (4.7±0.2)mm at 3 months after operation and at the last follow-up, significantly decreased from preoperative (3.1±0.5)mm (all P<0.01), but there was no significant difference in intervertebral space height at 3 months after operation and at the last follow-up ( P>0.05). The Cobb angle was (6.5±1.3)° and (6.3±1.2)° at 3 months after operation and at the last follow-up, significantly increased from preoperative (-5.4±2.2)° (all P<0.01), but there was no significant difference in Cobb angle at 3 months after operation and at the last follow-up ( P>0.05). The fusion rate of intervertebral bone grafting evaluated by Lenke grading was 100% at 3 months after operation. The ASIA grading was grade A in 15 patients, grade B in 42, grade C in 29, grade D in 12 and grade E in 7 at 3 months after operation. The patients showed varying degrees of improvement in postoperative ASIA grade except that 15 patients with preoperative ASIA grade A had partial recovery of limb sensation but no improvement in ASIA grade. The JOA score was (13.3±0.6)points and (13.1±0.6)points at 3 months after operation and at the last follow-up, significantly improved from preoperative (6.8±1.4)points (all P<0.01), but there was no significant difference in JOA score at 3 months after operation and at the last follow-up ( P>0.05). The rate of spinal cord functional recovery was (66.3±2.5)% at the last follow-up. All patients had no complications such as increased nerve damage or vascular damage. Conclusion:The classified reduction based on CT two-dimensional images for the surgical treatment of single segment facet joint dislocation in subaxial cervical spine has advantages of reduced facet joint dislocation, recovered intervertebral space height and physiological curvature, good intervertebral fusion and improved spinal cord function.
RESUMEN
Objective:To compare the efficacy between percutaneous vertebroplasty (PVP) with unilateral double-target puncture approach plus side opening propeller and traditional PVP in the treatment of Kümmell disease.Methods:A retrospective cohort study was conducted to analyze the clinical data of 40 patients with Kümmell disease admitted to Zhengzhou Orthopedic Hospital from January 2020 to June 2022, including 11 males and 29 females; aged 61-95 years [(74.3±9.5)years]. Twenty patients received the PVP with unilateral double-target puncture approach plus side opening propeller (observation group), and 20 patients were treated with traditional PVP (control group). The operation time, volume of cement injection and distribution levels of bone cement were compared between the two groups, as well as the visual analogue score (VAS), Oswestry dysfunction index (ODI), Cobb angle, anterior height of the vertebral body before operation and at 1 day and 6 months after operation. The incidence of complications was also compared between the two groups.Results:All patients were followed up for 6-12 months [(9.1±2.8)months]. The operation time was (40.3±4.5)minutes in the observation group and (38.6±3.5)minutes in the control group ( P>0.05). The volume of cement injection was (6.5±1.3)ml in the observation group, significantly more than that in the control group [(5.4±1.0)ml] ( P<0.01). The distribution levels of bone cement in the observation group (0 patient in Grade 1, 3 in Grade 2, and 17 in Grade 3) were better than those in the control group (1 patient in Grade 1, 15 in Grade 2, and 4 in Grade 3) ( P<0.01). There were no significant differences in the VAS, ODI, Cobb angle or anterior height of the vertebral body between the two groups before operation (all P>0.05). One day after operation, the VAS in the observation group and control group was (1.6±0.7)points and (2.5±0.8)points, with the ODI of 16.1±3.3 and 21.3±4.1, Cobb angle of (18.4±2.9)° and (21.4±2.0)° and anterior height of the vertebral body of (23.7±1.8)mm and (20.1±1.7)mm. Six months after operation, the VAS in the observation group and control group was (1.3±0.5)points and (2.3±0.9)points, with the ODI of 15.0±3.8 and 20.8±3.9, Cobb angle of (19.3±2.9)° and (22.4±1.7)°, and anterior height of the vertebral body of (23.4±1.8)mm and (19.8±1.6)mm. The VAS, ODI, Cobb angle and anterior height of the vertebral body in the observation group were better than those in the control group at 1 day and 6 months after operation (all P<0.01). The VAS, ODI, Cobb angle and anterior height of the vertebral body were significantly improved in the two groups at 1 day and 6 months after operation compared with those before operation (all P<0.01), but there were no significant differences between 1 day and 6 months after operation (all P>0.05). The incidence of complications was not significantly different between the two groups ( P>0.05). Conclusion:The PVP with unilateral double-target puncture approach plus lateral opening propeller not only allows for adequate and evenly distributed injection of bone cement, but also effectively reduces the pain, improves the quality of life, corrects the kyphosis and restores the height of the vertebral body in treating Kümmell disease compared with the traditional PVP.
RESUMEN
Objective:To compare the clinical efficacies of precision targeted and traditional percutaneous vertebroplasty (PVP) in the treatment of refracture of injured vertebra after operation for Kümmell disease.Methods:A retrospective cohort study was conducted to analyze the clinical data of 23 Kümmell disease patients suffering from refracture of injured vertebra after PVP in Zhengzhou Orthopedic Hospital from October 2014 to October 2018. The patients included 7 males and 16 females, aged 53-89 years [(69.3±3.5)years]. There were 11 patients of stage I Kümmell disease and 12 patients of stage II Kümmell disease. The vertebral distribution of fracture was T 11 (3 patients), T 12 (9 patients), L 1 (8 patients) and L 2 (3 patients). Eleven patients received traditional PVP treatment (traditional PVP group) and 12 patients received precision targeted PVP treatment (targeted PVP group). The operation time, amount of bone cement injection and filling of bone cement in the fracture space were compared between the two groups. The visual analogue score (VAS) and Oswestry disability index (ODI) were also compared before operation, at 2 days, 1 month, 3 months, 6 months after operation, and at the last follow-up. The rates of bone cement leakage and re-collapse of injured vertebra were observed in the two groups. Results:The patients were followed up for 12-36 months [(24.2±2.6)months]. There were no significant differences in the operation time or amount of bone cement injection between the two groups (all P>0.05). All the fracture spaces in the targeted PVP group were fully filled with bone cement, while 4 patients in the traditional PVP group showed inadequate filling of the fracture area ( P<0.05). The VAS values in the targeted PVP group were (8.9±0.5)points, (1.6±0.2)points, (1.7±0.1)points, (1.8±0.1)points, (1.9±0.3)points, and (1.8±0.4)points before operation, at 2 days, 1 month, 3 months, 6 months after operation and at the last follow-up; and those in the traditional PVP group were (9.1±0.9)points, (1.8±0.4)points, (1.8±0.2)points, (2.0±0.4)points, (2.1±0.2)points, and (2.4±0.3)points, respectively. The VAS values of both groups were significantly decreased at 2 days, 1 month, 3 months, 6 months after operation, and at the last follow-up compared with those before operation (all P<0.05), but there was no significant difference between different time points after operation (all P>0.05). No significant differences were found in the VAS values between the two groups before operation and at 2 days, 1 month, 3 months and 6 months after operation (all P>0.05). However, the VAS value in the targeted PVP group was significantly lower than that in the traditional PVP group at the last follow-up ( P<0.05). The ODI values in the targeted PVP group were 38.5±4.3, 7.2±2.3, 7.3±2.0, 7.2±1.8, 7.3±2.4, and 7.4±2.5 before operation and at 2 days, 1 month, 3 months, 6 months after operation, and at last follow-up; and those in the traditional PVP group were 37.8±4.1, 7.5±2.5, 7.7±1.9, 7.9±2.4, 8.1±2.6, and 9.6±2.4, respectively. The ODI values of both groups were significantly decreased at 2 days, 1 month, 3 months, 6 months after operation and at the last follow-up compared with those before operation (all P<0.05), but there were no significant differences between different time points after operation (all P>0.05). The ODI values were not significantly different between the two groups before operation and at 2 days, 1 month, 3 months, 6 months after operation (all P>0.05), but the ODI value in the targeted PVP group was significantly lower than that in the traditional PVP group at the last follow-up ( P<0.05). There were no significant differences in the rates of bone cement leakage or re-collapse of injured vertebra between the two groups (all P>0.05). Conclusion:Compared with traditional PVP treatment for refracture of injured vertebra after operation for Kümmell disease, targeted PVP can make bone cement injection fully dispersed, greatly reduce pain and promote functional recovery.
RESUMEN
Objective:To compare the efficacies of posterior long segment instrumentation combined with transpedicular impaction bone grafting or with bone cement augmentation in treating stage III Kümmell disease.Methods:A retrospective cohort study was conducted to analyze the clinical data of 38 patients with stage III Kümmell disease who were admitted to Zhengzhou Orthopedic Hospital between January 2016 and December 2020. The study included 8 male and 30 female patients, with ages ranging from 59 to 81 years [(68.9±4.9)years]. The vertebral fractures occurred at T 8 in 1 patient, T 11 in 9 patients, T 12 in 10 patients, and L 2 in 10 patients. Seventeen patients underwent posterior long segment instrumentation combined with transpedicular impaction bone grafting (impaction bone grafting group), and 21 patients underwent posterior long segment instrumentation combined with bone cement augmentation (bone cement group). The surgical duration, intraoperative blood loss, and incidences of postoperative complications were compared between the two groups. Additionally, the visual analogue score (VAS), Japanese orthopedic association (JOA) score, and Cobb angle were compared before the operation, at 1 week and 3 months post-operation, and at the final follow-up for both groups. The study also compared bone healing at the last follow-up and postoperative complication rates between the two groups. Results:All the patients were followed up for 24-35 months [(28.7±2.9)months]. The impaction bone grafting group had a surgical duration of (150.7±25.4)minutes and intraoperative blood loss of (285.3±48.6)ml, significantly different from those in the bone cement group [(132.0±21.1)minutes, (251.4±44.8)ml] (all P<0.05). Before the operation, there were no significant differences in the VAS, JOA score, or Cobb angle between the two groups (all P>0.05).The VAS was (3.2±0.8)points, (2.7±0.5)points and (2.2±0.7)points in the impaction bone grafting group and was (2.7±0.6)points, (2.6±0.7)points and (2.4±0.8)points in the bone cement group at 1 week and 3 months post-operation and at the final follow-up, respectively. The VAS in the impaction bone grafting group was significantly higher than that in the bone cement group at 1 week post-operation ( P<0.05); however, no significant differences were found at 3 months post-operation or at the last follow-up (all P>0.05). There was no significant difference in the JOA score between the two groups at 1 week or 3 months post-operation, or at the final follow-up (all P>0.05). The Cobb angle in the impaction bone grafting group was (5.1±1.3)°, (5.9±1.8)° and (6.5±2.5)° at 1 week and 3 months post-operation, and at the final follow-up, significantly lower than that in the bone cement group [(8.4±1.6)°, (12.6±2.1)°, and (14.5±3.3)°] (all P<0.01). All the patients in the impaction bone grafting group achieved bone healing at the last follow-up. One patient in the impaction bone grafting group experienced delayed incision healing, whereas two patients in the bone cement group had poor bone healing. The complication rate was 5.9% (1/17) in the impaction bone grafting group and 9.5% (2/21) in the bone cement group ( P>0.05). Conclusions:Posterior long segment instrumentation combined with transpedicular impaction bone grafting or with bone cement augmentation are both effective in alleviating pain and improving the spinal function for stage III Kümmell disease. The former procedure is associated with longer surgical duration and increased intraoperative blood loss, but it can provide superior correction and maintenance of kyphosis deformity, promoting the healing of the injured vertebrae.
RESUMEN
Objective:To evaluate the clinical effects of posterior reduction in the treatment of acute severe traumatic lumbar spondylolisthesis.Methods:A retrospective study was conducted to analyze the clinical data of 12 patients with acute severe traumatic lumbar spondylolisthesis who had been treated by posterior reduction at Department of Spinal Surgery, Zhengzhou Orthopaedic Hospital from June 2010 to December 2018. There were 7 males and 5 females with an age of (25.7±1.8) years. The spondylolisthesis was at L4 in 4 cases and at L5 in 8 cases, and grade Ⅲ in 7 cases, grade Ⅳ in 4 cases and grade Ⅴ in 1 case according to the Meyerding classification. By the American Spinal Injury Association (ASIA) grading, the preoperative neurological function was at level B in 6 cases, at level C in 4 cases, and at level D in 2 cases. All the 12 patients underwent posterior reduction and internal fixation with pedicle screws, as well as intervertebral bone graft fusion. Operation time and intraoperative blood loss were recorded. Clinical efficacy was evaluated by visual analogue scale (VAS) and Oswestry disability index (ODI) before and after surgery, and neurological function was evaluated by ASIA grading. X-ray, CT plain scan and reconstruction were used to observe internal fixation and bone grafting.Results:All patients were followed up for (18.5±2.1) months. The operation time was (165.7±42.3) min and the blood loss (497.7±75.3) mL. The VAS pain scores [(2.7±0.3) points and (1.8±0.2) points] and ODIs (18.2%±2.3% and 14.5%±2.6%) at 2 weeks after operation and at the last follow-up were significantly lower than the preoperational values [(8.5±0.6) points and 72.3%±12.3%] ( P<0.05), but there was no statistically significant difference between 2 weeks after operation and the last follow-up ( P>0.05). At the last follow-up, X-rays and CT scans showed good fixation and adequate bone grafting; the spondylolisthesis was grade 0 in 10 cases and grade I in 2 cases; the ASIA level of neurological function was C in 2 cases, D in 3 cases, and E in 7 cases. Healing of surgical incision was delayed in 2 patients but responded to symptomatic treatment. Follow-ups observed no such complications as loosening or pulling out of internal fixation. Conclusion:In the treatment of acute severe traumatic lumbar spondylolisthesis, posterior reduction can effectively restore the spondylolisthesis sequence and restore spinal stability, leading to satisfactory curative outcomes.
RESUMEN
ABSTRACT Objective: To investigate the risk factors for predicting atrial high-rate episodes (AHREs) detected by cardiac implantable electronic devices (CIEDs). Methods: A total of 140 patients with CIED in our hospital from June 2013 to June 2018 were included and were followed up to observe whether they had AHREs. AHRE are defined as atrial rate ≥ 175 times/minute, lasting > 5 minutes, and reviewed by an experienced electrophysiologist with unclear clinical diagnosis. The patients fasted for 12 hours after implantation, and blood samples were collected for biochemical, lipid, and whole blood count detection. Follow-up was regular after discharge to record follow-up data of each patient and conduct statistical analysis. Results: One hundred and forty patients were implanted with dual-chamber pacemakers, their median age was 70 years old, 44.29% were male, 27 patients had AHRE within one year, and AHRE incidence rate was 19.29%. The microcytic to hypochromic (M/H) ratio was calculated for all AHRE patients and compared with the patients without AHRE; the M/H value of AHRE patients was significantly higher. Throughout the entire follow-up period, a total of 44 patients developed AHRE; when adjusted by multivariate analysis, only M/H ratio ≥ 4.5 vs. < 4.5 had statistical significance, and the adjusted hazard ratio value was 4.313 (1.675-11.105). Conclusion: As an indicator, M/H ratio may play an important role in the occurrence and development of atrial fibrillation and can be used as a predictor of AHRE in patients with CIED.
RESUMEN
Using data mining technology, the rules of acupoint selection of acupuncture and moxibustion were explored in treatment of stroke-related pneumonia. The clinical articles of acupuncture and moxibustion in treatment of stroke-related pneumonia were retrieved from CNKI, SinoMed, Wanfang and VIP databases from their inception through to January l 2021, and then, the acupuncture-moxibustion prescription database was set up for stroke-related pneumonia. SPSS Modeler 18.0 Apriori algorithm was adopted to analyze the association rules of acupoints and draw complex network diagrams. SPSS26.0 was used in clustering analysis of acupoints. Finally, a total of 44 articles were included, with 51 acupoint prescriptions and 82 acupoints extracted. The total frequency of acupoints was 340 times. The high-frequency acupoints in treatment with acupuncture and moxibustion for stroke-related pneumonia were Feishu (BL 13), Fenglong (ST 40), Hegu (LI 4), etc. These acupoints were mainly distributed on the limbs and back and mostly from yang meridians. Of these extracted acupoints, the five-shu points, convergent points and back-shu points were selected specially. Regarding acupoint combination, the association of Quchi (LI 11) had the highest support with Hegu (LI 4) and Zusanli (ST 36). The core prescription of acupuncture-moxibustion treatment for stroke-related pneumonia could be composed of Quchi (LI 11), Hegu (LI 4), Zusanli (ST 36), Fenglong (ST 40) and Taichong (LR 3).

Hip fracture is the most common traumatic disease in the older adult patients, and its incidence is rising year by year. There are various clinical scoring systems for predicting postoperative complications and mortality. However, most scoring systems are not suitable for predicting postoperative complications and mortality of hip fracture. This paper summarizes the establishment, calculation, application extension and clinical application of Nottingham Hip Fracture Score, and elaborates the clinical application of Nottingham Hip Fracture Score in hip fracture patients.
RESUMEN
Objective:To compare the clinical efficacy of long/short segment posterior instrumentation combined with transpedicular impaction bone grafting for stage III Kümmell's disease.Methods:A retrospective case control study was conducted to analyze the clinical data of 45 patients with stage III Kümmell's disease admitted to Zhengzhou Orthopaedics Hospital from June 2012 to June 2019, There were 8 males and 37 females, aged 58-84 years [(68.8±3.5)years]. Segment of injury was T 11 in 5 patients, T 12 in 18, L 1 in 15, and L 2 in 7. A total of 24 patients were treated with posterior long segment pedicle screw fixation combined with pedicle screw compression and bone grafting (long segment group), and 21 patients were treated with posterior short segment pedicle screw fixation combined with pedicle screw compression and bone grafting (short segment group). For patients with severe osteoporosis, pedicle screws were augmented with bone cement. The operation time and blood loss were compared between the two groups. The visual analogue scale (VAS) was used to evaluate the degree of low back pain, and the Japanese Orthopaedic Association (JOA) score was used to evaluate the lumbar function at postoperative 2 weeks and 1 year. According to X-ray film and CT examination, the bone healing of the grafted vertebral body and the changes of Cobb angle of injured vertebrae were further evaluated. The complications were observed. Results:All patients were followed up for 15-48 months[(31.2±2.3)months]. There were no significant differences between the two groups in operation time and intraoperative blood loss ( P>0.05). The bone grafts in the vertebrae healed well in both groups at 1 year after operation. The Cobb angle, VAS and JOA score in both groups improved at 2 weeks and 1 year after operation ( P<0.01). There was no significant difference in Cobb angle, VAS and JOA score between the two groups at 2 weeks after operation ( P>0.05). The Cobb angle in short segment group [(14.8±6.3)°] was significantly higher than that in long segment group [(8.5±3.3)°] at 1 year after operation ( P<0.01), but there was no significant difference in VAS and JOA scores between the two groups ( P>0.05). There was no loosening or breakage of internal fixation in both groups. Conclusions:For stage III Kümmell's disease, both long and short segment posterior instrumentation combined with transpedicular impaction bone grafting can effectively restore the vertebral height, improve kyphosis and reduce dysfunction. However, long segment can better maintain spine stability, prevent vertebral collapse and progression of local kyphosis Cobb angle when compared with short segment fixation.
RESUMEN
Objective:To investigate the efficacy of stage I anterior cervical reduction, decompression, interbody fusion and internal fixation of single-segment lower cervical injury of AO type C subtype F4.Methods:A retrospective case series study was made on 45 patients with single-segment lower cervical injury of AO C type F4 subtype admitted to Zhengzhou Orthopedic Hospital from January 2012 to December 2019. The study included 31 males and 14 females with the age of (48.5±3.7)years (range, 23-78 years). Segment of injury was located at C 4/5 in 11 patients, at C 5/6 in 19, and at C 6/7 in 15. Under general anesthesia, all patients (16 unilateral injury and 29 bilateral injury) underwent stage I anterior cervical reduction, decompression, interbody fusion and internal fixation within 24 hours after injury. The interbody fusion methods included autogenous iliac bone in 28 patients and cervical fusion cage in 17. The operation time, blood loss, reduction time and correction rate of zygapophysial joints, postoperative complications and incision healing were analyzed. The height of cervical intervertebral space and Cobb angle were measured through X-ray of lateral cervical vertebrae before operation and3 months after operation to assess the cervical physiological curvature. The type of injury was clarified according to Lenke classification through coronal and sagittal CT scanning to determine the intervertebral bone graft fusion rate. The intraspinal spinal cord decompression was observed through MRI. The nerve function was assessed before operation and 3 months after operation using American Spinal Injury Association (ASIA) scale and Japanese Orthopedic Association (JOA) score, and the improvement rate was measured. Results:All the patients were followed up for (6.1±3.6)months (range, 3-9 months). The operation time was (55.1±8.2)minutes (range, 40-75 minutes), and intraoperative blood loss was (45.2±5.3)ml (range, 40-80 ml). The Zygapophysial joint reduction took (2.1±0.5)minutes (range, 1.5-3.0 minutes), with a success rate of 100%. Surgical procedures were performed with no postoperative complications such as aggravated spinal cord injury, large vascular injury or esophageal lesion. All the patients obtained Class I incision healing at first stage. The height of cervical intervertebral space was improved from preoperative (3.3±0.6)mm to (4.9±0.8)mm at postoperative 3 months ( P<0.05). The Cobb angle was increased from preoperative (-4.6±3.6)° to (6.5±2.1)° at postoperative 3 months ( P<0.01). According to Lenke classification, the intervertebral body fusion was good at postoperative 3 months, including Grade A in 41 patients and Grade B in 4. The rest of the patients showed varying degrees of neurological recovery according to ASIA scale, except for 6 patients with ASIA Grade A. The JOA score was improved from preoperative (7.4±2.3)points to (15.0±3.2)points at postoperative 3 months ( P<0.05), with the improvement rate of (73.3±17.6)%. Conclusion:For stage I anterior cervical reduction, decompression, interbody fusion and internal fixation of single-segment lower cervical injury of AO type C subtype F4, early surgical decompression is needed so as to reduce the perched facet or dislocated zygapophyseal joints and effectively improve the cervical spinal cord function.

Targeting the poor powder characteristics of the contents in Hewei Jiangni Capsules, this study characterized the powder properties of the contents and employed particle design technique for improving the content quality. The content composite particles of Hewei Jiangni Capsules prepared by the particle design technique were evaluated by scanning electron microscopy(SEM), followed by infrared ray(IR), content uniformity, and in vitro dissolution detection. It was found that there was a good correlation between the crushed particle size of slices and the crushing time, and the calcined Haematitum was responsible for the poor content uniformity. After the fine powder of calcined Haematitum was super-finely ground for 8.5 min and those of the other contents in the capsule for 1 min, they were prepared into the composite particles, whose property characterizations were compared with those of the physical mixtures. The content uniformity of the prepared composite particles was significantly improved, and the preparation process was stable and reliable. The adoption of particle design technology to correct the poor uniformity of the physical mixture, solve the pharmaceutical defects of Hewei Jiangni Capsules, and improve the quality of prescriptions has provided important reference for the clinical application and development of Chinese medicinal preparations.
