Guideline for the diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients (version 2023) / 中华创伤杂志

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

Comparison of Gamma 3 U-blade system and Gamma 3 nails in treatment of elderly patients with osteoporotic unstable femoral intertrochanteric fracture / 中华创伤骨科杂志

Objective:To compare the short-term therapeutic effects of Gamma 3 U-Blade system and Gamma 3 nails in the treatment of elderly patients with osteoporotic unstable intertrochanteric fracture.Methods:The data of 70 elderly patients with osteoporotic unstable intertrochanteric fracture were retrospectively analyzed who had been admitted to the Department of Orthopedics, Wuhan Fourth Hospital from June 2018 to December 2020. They were divided into 2 groups according to their treatments. In the U-Blade group of 35 cases subjected to fixation with Gamma 3 U-Blade system, there were 14 males and 21 females with an age of (77.7 ± 4.8) years; in the Gamma 3 nail group of 35 cases subjected to fixation with Gamma 3 nails, there were 14 males and 21 females with an age of (79.3 ± 5.2) years. The 2 groups were compared in terms of operation time, intraoperative blood loss, apex distance, fracture union time, postoperative complications, timed up and go (TUG) at postoperative 2 weeks, 3 months and 6 months, and hip function at postoperative 9 months.Results:There was no statistically significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). There was no significant difference either in operation time, intraoperative blood loss or apex distance between the 2 groups ( P>0.05). The fracture union time [(12.0 ± 0.2) weeks] and Harris hip score at postoperative 9 months [90 (90, 91)] in the U-Blade group were insignificantly different from those in the Gamma 3 nail group [(12.0 ± 0.3) weeks and 91 (89, 91)] ( P>0.05). The rate of implant-related complications in the U-Blade group [0% (0/35)] was significantly lower than that in the Gamma 3 nail group [17.1% (6/35)] and the TUGs at postoperative 2 weeks and 3 months [(80.2 ± 3.6) s and 45 (43, 49) s] in the former were significantly shorter than those in the latter [(89.3 ± 4.2) s and 56 (54, 59) s] ( P<0.05). Conclusion:In the treatment of elderly patients with osteoporotic unstable intertrochanteric fracture, compared with traditional Gamma 3 nails, Gamma 3 U-Blade system can reduce implant-related complications and facilitate early recovery of walking ability.

Arthroscopic medullary decompression combined with platelet-rich plasma therapy for bone marrow edema of the talus / 中华创伤杂志

Objective:To report the efficacy of arthroscopic medullary decompression combined with platelet-rich plasma (PRP) in the treatment of bone marrow edema of the talus.Methods:A retrospective case series study was used to analyze the clinical data of 17 patients with bone marrow edema of the talus admitted to Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2018 to July 2020. There were 11 males and 6 females, with the age range of 15-56 years [(45.7±4.3)years]. All patients were subjected to arthroscopic medullary decompression combined with the administration of PRP. Operation time and wound healing were recorded. Maximum area of bone marrow edema was measured by MRI preoperatively and at 6 and 12 months postoperatively. Ankle range of motion (ROM), visual analog score (VAS) and American Association of Foot and Ankle Surgery (AOFAS) ankle-hindfoot score were measured preoperatively and at 6 and 12 months postoperatively. Complications were also detected.Results:All patients were followed up for 12-41 months [(16.7±2.1)months]. Operation time was 45.2-68.5 minutes [(53.4±12.4)minutes]. All wounds were healed at stage I. The maximum area of bone marrow edema decreased from (28.2±6.9)mm 2 preoperatively to (16.3±5.7)mm 2 at 6 months postoperatively and to (7.1±1.7)mm 2 at 12 months postoperatively (all P<0.01). Ankle ROM increased from (52.2±8.9)° preoperatively to (72.3±3.1)° at 6 months postoperatively and to (83.1±2.8)° at 12 months postoperatively (all P<0.01). VAS decreased from (8.2±0.6)points preoperatively to (6.5±0.4)points at 6 months postoperatively and to (3.1±0.8)points at 12 months postoperatively (all P<0.01). AOFAS ankle-hindfoot score increased from (32.4±4.8)points preoperatively to (54.4±6.5)points at 6 months postoperatively and to (88.7±4.3)points at 12 months postoperatively (all P<0.01). There were significant differences in maximum area of bone marrow edema of the talus, ankle ROM, VAS and AOFAS ankle-hindfoot score at 12 months postoperatively when compared with those at 6 months postoperatively (all P<0.01). One patient showed the symptom of localized skin numbness postoperatively, and improved with nerve nutrition therapy. Conclusion:Arthroscopic medullary decompression combined with PRP therapy for bone marrow edema of the talus presents good short-term clinical benefits in terms of reduced extent of bone marrow edema, improved ankle ROM, attenuated pain, improved ankle joint function and few postoperative complications.

Expert consensus on diagnosis, prevention and treatment of perioperative lower extremity vein thrombosis in orthopedic trauma patients (2022 edition) / 中华创伤杂志

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

Prevention and treatment of complications after open wedge high tibial osteotomy for knee arthritis / 中华创伤骨科杂志

Open wedge high tibial osteotomy (OWHTO) is one of the effective treatments of medial knee arthritis and an important step in the treatment of knee arthritis. However, with the popularization of OWHTO, more and more of its related complications have been reported, including under- and over-correction of the alignment, tilted joint line, fracture of the cortical hinge, and changes in the posterior tilt of the tibial plateau. This paper reviewed the domestic and foreign research literature on the OWHTO treatment of knee arthritis to analyze the incidence of intraoperative and postoperative complications, treatment strategies and prevention methods concerning the complications in the treatment of OWHTO. A comprehensive understanding of the prevention and treatment methods of the complications can help avoid and reduce some of the complications so that OWHTO can be popularized more widely.

Is subfibular ossicle excision necessary in the modified Brostr?m procedure for chronic lateral ankle instability? / 中华创伤骨科杂志

Objective:To investigate the effect of subfibular ossicle excision on the clinical efficacy of Brostr?m procedure for chronic lateral ankle instability (CLAI).Methods:From March 2014 to December 2018, 76 patients were treated by the modified Brostr?m procedure using the suture anchor technique for CLAI at Department of Foot & Ankle Surgery, Wuhan Fourth Hospital. Of them, 33 had subfibular ossicles (SFO group) and 43 did not (NSFO group). In the SFO group, there were 19 males and 14 females, aged (28.4±8.6) years; in the NSFO group, there were 21 males and 22 females, aged (27.8±7.4) years. Subfibular ossicles were excised in the SFO group. The 2 groups were compared in terms of American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores and visual analogue scale (VAS) pain scores at preoperation and the final follow-up.Results:The 2 groups were comparable due to insignificant differences between them in their preoperative general data ( P>0.05). All the patients were followed up for 24 to 72 months (average, 28 months). The AOFAS ankle-hindfoot scores improved significantly from 54.5±3.4 to 95.7±2.1 in the SFO group and significantly from 56.2±2.7 to 95.2±2.4 in the NSFO group at the final follow-up; the VAS scores reduced significantly from 5.7±1.8 to 1.6±1.4 in the SFO group and significantly from 5.7±1.6 to 1.7±1.2 in the NSFO group at the final follow-up (all P<0.05). No significant differences were found between the 2 groups in terms of AOFAS or VAS scores at the final follow-up ( P>0.05). Conclusion:Since the modified Brostr?m procedure plus subfibular ossicle excision may result in similar good clinical efficacy as merely the modified Brostr?m procedure may for the CLAI patients without subfibular ossicle, subfibular ossicle excision should be suggested for the CLAI patients with subfibular ossicle.

A young patient with recurrent myocardial infarction within a half month / 中南大学学报(医学版)

In this study, we reported a young male patient with acute chest pain who was diagnosed as myocardial infarction. The regular medication was performed following coronary intervention. Under such condition, this patient had 3 times myocardial infarction within a half month. The laboratory results showed that there might be a state of hypercoagulability. Aspirin combined with clopidogrel and other treatment were administrated. Meanwhile, the examination demonstrated that there was aspirin-resistant in the patient. The antiplatelet drug and extended anticoagulation therapy were carried out. There was no further myocardial infarction, and no coronary arteries stenosis was found in the re-examination angiography. Aspirin resistance and hypercoagulability should be considered when patients occurred the repeated myocardial infarction after regular medication and coronary intervention. Replacement of the antiplatelet treatment or combination with anticoagulant therapy is necessary in similar patient to avoid the sever consequence.

Treatment of tibial plateau fractures involving external posterior condyle collapse with 3D printed osteotomy guide plate combined with "Jail" screw technique / 中华骨科杂志

Objective:To investigate the clinical efficacy of 3D printed osteotomy guide plate combined with "Jail" screw technique in the treatment of tibial plateau fractures involving external posterior condylar collapse.Methods:From January 2016 to January 2021, 41 patients (22 males and 19 females) with tibial plateau fractures involving external posterior condylar collapse were treated with 3D printed osteotomy guide plate combined with "Jail" screw technique and followed up. The age was 47.4±11.5 years (range, 22-69 years). According to Schatzker fracture type, 18 cases were type IV, 14 cases were type V and 9 cases were type VI. All fractures were closed, and 12 of them were complicated with lateral meniscus injury, but none of them were complicated with nerve and vascular injury. The time from injury to operation was 7.2±3.4 d (range, 4-17 d). All patients underwent 3D CT scanning and digital modeling before operation. According to the modeling results, a 1∶1 solid size fracture model was made by 3D printing, and the osteotomy guide plate and the "Jail" screw preset guide plate were designed. During the operation, the tibial lateral condyle osteotomy was performed with customized osteotomy guide plate. After reduction, the fixation of the fracture was performed with the preset guide plate using "Jail" screw. Postoperative fracture reduction was evaluated according to Rasmussen score, and knee function was evaluated by Hospital for Special Surgery (HSS) score.Results:All the 41 patients were followed up for 15.2±5.8 months (range, 6-26 months). Immediate postoperative radiographs showed good fracture reduction, and the average healing time was 14.1±1.2 weeks (range, 12-17 weeks). One year after operation, the Rasmussen score of knee joint was 17.4±1.6 points (range, 13-19 points), of which 31 cases were excellent, 8 cases were good, and 2 cases were fair, with an excellent/good rate of 95% (39/41). HSS scores was 87.3±5.6 points (range, 68-95 points), including 30 excellent cases, 10 good cases and 1 fair case, with an excellent/good rate of 98% (40/41). The range of motion of knee joint was 126.8°±3.8°. At the last follow-up, no serious complications such as common peroneal nerve injury, popliteal vascular injury, postoperative infection, or internal fixation failure occurred.Conclusion:3D printed osteotomy guide plate combined with "Jail" nail placement technique is an effective method for tibial plateau fractures involving external posterior condylar collapse, and the postoperative treatment results are satisfactory. The use of customized osteotomy guide plate is more accurate and less damaging. The use of "Jail" screw preset guide plate can ensure more accurate screw placement.

Postoperative deep vein thrombosis in patients after selective ankle or mid-hindfoot surgery / 中华创伤骨科杂志

Objective:To investigate the prevalence of deep vein thrombosis (DVT) in patients after selective ankle or mid-hindfoot surgery.Methods:A retrospective analysis was conducted of the 109 patients with ankle or mid-hindfoot disease who had been treated from January 2018 to December 2019 at Department of Orthopaedics, Wuhan Fourth Hospital. They were 65 males and 44 females, aged from 32 to 74 years (average, 49.0 years). Ultrasonography was performed at preoperative 1 day, postoperative 2 and 6 weeks to determine the occurrence, location and clinical symptoms of DVT. The patients were divided into an early DVT group, a late DVT group and a DVT-free group according to the occurrence and onset time of DVT. The 3 groups were compared in terms of gender, age, body mass index and tourniquet duration.Results:The incidence of postoperative lower limb DVT was 22.9% (25/109). All the thromboses were observed beyond the distal plane of the popliteal vein. 72.0% of the DVT patients were clinically asymptomatic. There was no significant difference in gender, age or body mass index between early DVT group ( n=17), late DVT group ( n=8) and DVT-free group ( n=84) ( P>0.05). The incidence was 68.0% (17/25) for early DVT and 32.0% (8/25) for late DVT. The intraoperative tourniquet duration for the early DVT group [(77.7±12.3) min] was significantly longer than that for the late DVT group [(66.8±11.2) min] and for the DVT-free group [(65.9±10.5) min] ( P<0.05). Conclusions:The majority of postoperative DVTs may be clinically asymptomatic in patients after selective ankle or mid-hindfoot surgery. Although DVT tends to occur within postoperative 2 weeks, its risk may continue after 2 weeks. Increased tourniquet duration may be associated with incidence of early DVT.

Comparison of arthroscopy-assisted reduction and internal fixation versus open reduction and internal fixation for tibial plateau fractures / 中华创伤骨科杂志

Objective:To compare the efficacy between arthroscopy-assisted reduction and internal fixation (ARIF) versus open reduction and internal fixation (ORIF) in the treatment of tibial plateau fractures.Methods:A retrospective analysis was done of the 75 patients with tibial plateau fracture who had been treated by ARIF or ORIF at Department of Orthopaedics, Union Hospital Affiliated to Tongji Medical Collage from January 2016 to August 2018. They were 58 men and 17 women, aged from 20 to 54 years (average, 47 years). The left side was affected in 42 cases and the right side in 33. By the Schatzker classification, there were 23 cases of type Ⅰ, 49 cases of type Ⅱ and 3 cases of type Ⅲ. Of them, 40 were treated by ARIF and 35 by ORIF. The 2 groups were compared in terms of operation time, incision length, intraoperative blood loss, hospital stay, postoperative complications and the Hospital for Special Surgery (HSS) scores 12 months after operation.Results:There was no statistically significant difference between the 2 groups in the preoperative general data, showing the 2 groups were comparable ( P>0.05). The patients were followed up for 12 to 15 months (average, 13.5 months) after operation. The wounds in the 75 patients healed at one stage with no complications like neurovascular lesions. All the fractures healed within 6 months after operation. Compared with the ORIF group, the ARIF group had significantly longer operation time (58.3 min ± 4.2 min versus 48.4 min ± 5.2 min), a significantly shorter incision (4.3 cm ± 0.9 cm versus 6.2 cm ± 0.8 cm), and significantly less intraoperative blood loss (60.8 mL ± 4.5 mL versus 72.8 mL ± 6.5 mL) ( P<0.05). There was no significant difference between the 2 groups in hospital stay (5.1 d ± 0.6 d versus 5.5 d ± 1.6 d) ( P>0.05). Fifteen patients in the ARIF group and 5 in the ORIF group were complicated with soft tissue injury, showing a statistically significant difference ( P<0.05). The excellent and good rate by HSS scores was 100% (40/40) for the ARIF group and 85% (34/40) for the ORIF group, showing no significant difference ( P>0.05). Conclusions:In the treatment of tibial plateau fractures of Schatzker types Ⅰ-Ⅲ, both ARIF and ORIF may result in good efficacy. However, ARIF can evaluate and treat the complicated soft tissue injuries to the knee joint more precisely, showing advantages of shorter operation time, a smaller incision and less blood loss.

Surgical management strategies for orthopedic trauma patients under epidemic of novel coronavirus pneumonia / 中华创伤杂志

With the outbreak of novel coronavirus pneumonia (NCP) induced by 2019 novel coronavirus (2019-nCoV) in Wuhan, Hubei Province in December 2019, more and more suspected or confirmed cases have been found in various regions of China. Although China has adopted unprecedented strict quarantine and closed management measures to prevent the spreading of the disease, Department of Traumatic Orthopedics may still have to manage NCP patients with open fractures or severe trauma that require emergency surgery. Therefore, the identification and management of 2019-nCoV infection as soon as possible as well as the protection of all medical staff involved in the emergency treatment of patients are the severe challenges faced by orthopedic traumatologists during the prevention and control of NCP. Based on the characteristics of such patients and related diagnosis and treatment experiences during the epidemic of NCP, the authors formulate the surgical management strategies for orthopedic trauma patients.

Objective:To report our experience in the emergent foot and ankle surgery in the epidemic of COVID-19.Methods:The data of 18 patients with acute foot and ankle injury were reviewed who had been admitted to the Department of Foot and Ankle Surgery, Wuhan Fourth Hospital from 20th January, 2020 to 26th February, 2020. They were 11 men and 7 women, aged from 18 to 70 years (average, 42.5 years). There were 5 cases of acute open injury and 13 ones of acute closed injury. COVID-19 infection was diagnosed or suspected in 5 cases but not in the other 13 cases. Emergency operation was carried out for 2 patients with open injury plus COVID-19 infection and one with complicated pilon fracture plus COVID-19 infection, one of whom received secondary operation. One patient with closed fracture of the left calcaneus plus COVID-19 infection was hospitalized from emergency department for secondary surgery, and another with closed fracture of the right lateral malleolus was referred to the isolation ward after emergency plaster fixation. Of the 10 patients with closed injury but without COVID-19 infection, 3 received conventional secondary surgery after admission and the others conservative treatment at the outpatient department. Recorded were COVID-19 infections in the patients after admission and in the medical staff. The measures taken and experience in control and prevention of COVID-19 infection after outbreak of the epidemic were reviewed.Results:Of the 11 patients who had been hospitalized for foot and ankle injury in emergency, 5 were definitely diagnosed of or suspected of COVID-19 infection and 6 free of COVID-19 infection. During hospitalization, COVID-19 infection was confirmed in the 5 cases and no COVID-19 infection occurred in the other 6 patients. No COVID-19 infection occurred in the medical staff; no cross infection was observed between the patients and the medical staff.Conclusions:Reasonable strategies are advised to balance the foot and ankle surgery and epidemic prevention. A simplified management is not advised for all the cases. The operative procedures in emergent foot and ankle surgery should be optimized in line with the epidemic control and prevention principles to facilitate functional rehabilitation for the patients.

Anatomical reconstruction of the lateral ankle ligament with an individualized 3D printed drill template / 中华创伤骨科杂志

Objective:To evaluate the clinical application of an individualized 3D printed drill template to create a fibular channel in the anatomical reconstruction of the lateral ankle ligament for chronic lateral ankle instability.Methods:From October 2012 to June 2015, 15 patients with lateral ankle in-stability underwent surgery at Department of Foot and Ankle Surgery, The Fourth Hospital of Wuhan.They were 4 men and 11 women, with a mean age of 26.3 years (range, from 18 to 42 years).For each of them, anatomical reconstruction of the lateral ankle ligament was performed through a fibular channel which was created with the aid of an individualized 3D printed drill template.The American Orthopaedic Foot and Ankle Society (AOFAS) and Visual Analogue Scale (VAS) scores were used to assess the patients preoperation and at the last follow-up.Results:The 15 patients obtained a mean follow-up of 15.2 months (range, from 12 to 18 months).Their preoperative AOFAS scores (47.1±3.8) were increased to 88.3±4.7 at the last fol-low-up, and their preoperative VAS scores (5.8±1.8) decreased to 1.55±1.35 at the last follow-up, showing significant differences ( P<0.05).There were 11 excellent and 4 good cases by the AOFAS ankle-hindfoot scale.No significant complications were found. Conclusion:In the anatomical reconstruction of the lateral ankle ligament for chronic lateral ankle instability, an individualized 3D printed drill template can help create a fibular channel which exactly fits each individual, leading to positive therapeutic effects.

Gamma 3 nails combined with hollow compression screw fixation for intertrochanteric fracture of risky external wall type / 中华创伤骨科杂志

Objective:To evaluate Gamma 3 nails combined with hollow compression screw fixation in the treatment of intertrochanteric fracture of risky external wall type.Methods:From November 2015 to December 2017, 60 patients with intertrochanteric fracture of risky external wall type were treated at Department of Orthopaedic Surgery, Wuhan Fourth Hospital. Of them, 27 ones, 15 males and 12 females with an age of 57.5 years±16.2 years (group A), were fixated with Gamma 3 nails and hollow compression screws, including 14 cases of AO type of 31-A2.2 and 13 cases of AO type of 31-A2.3. The other 33 patients, 18 males and 15 females with an age of 59.3 years±15.1 years (group B), were fixated with Gamma 3 nails alone, including 17 cases of AO type of 31-A2.2 and 16 cases of AO type of 31-A2.3. The 2 groups were compared in terms of operation time, hospitalization time, intraoperative blood loss, weight-bearing time, fracture healing time, complications and Harris hip scores at the final follow-up.Results:The 2 groups were comparable due to insignificant differences between them in preoperative general data ( P>0.05). The 60 patients obtained an average follow-up of 22.6 months (from 12 to 36 months). There were no statistically significant differences in operation time, intraoperative blood loss or hospital stay between the 2 groups ( P>0.05). Group A had a significantly lower incidence of external wall redisplacement [7.4% (2/27)], significantly shorter weight-bearing time(5.4 weeks±1.0 weeks) and fracture healing time(18.3 weeks±3.9 weeks), and significantly higher Harris hip scores at the final follow-up (89.3±7.1) than group B did [24.2% (8/33), 7.4 weeks±1.3 weeks, 21.7 weeks±5.6 weeks and 79.5±8.3, respectively] (all P< 0.05). Follow-ups revealed no complications like femoral head cutting, implant breakage, deep vein thrombosis of lower limb, fat embolism, hip varus deformity or nail breakage in either group. Conclusion:In the treatment of intertrochanteric fracture of risky external wall type, compared with Gamma 3 nails alone, Gamma 3 nails combined with hollow compression screw fixation can avoid external wall displacement or fixation failure after external medullary fixation or intramedullary fixation alone but does not increase operation time or intraoperative blood loss, leading to better functional recovery.

Surgical management strategies for orthopedic trauma patients under epidemic of corona virus disease 2019 / 中华创伤杂志

With the outbreak of corona virus disease 2019 (COVID-19) caused by 2019 novel coronavirus (2019-nCoV) in Wuhan, Hubei Province in December 2019, more and more suspected or confirmed patients have been found in various regions of China. Although China has adopted unprecedented strict quarantine and closed management measures to prevent the spreading of the disease, Department of Traumatic Orthopedics may still have to manage COVID-19 patients with open fractures or severe trauma that require emergency surgery. Therefore, the identification and management of 2019-nCoV infection as soon as possible as well as the protection of all medical staff involved in the emergency treatment of patients are the serious challenges faced by orthopedic traumatologists during the prevention and control of COVID-19. Based on the characteristics of such patients and related diagnosis and treatment experiences during the epidemic of COVID-19, the authors formulate the strategies of surgical management and infection prevention and control for orthopedic trauma patients.

The clinical analysis of 29 patients in spontaneous intraspinal canal hematoma / 中华急诊医学杂志

Objective To explore the management of spontaneous intraspinal hematoma.Methods From January 2011 to July 2018,29 cases with spontaneous intraspinal hematoma were admitted to our department.Date on etiology,clinical presentation,radiological features,treatment strategy and prognosis were analyzed retrospectively.The prognosis was assessed by American Spinal Injury Association impairment scale (ASIA) before and after the treatment.Results Total of 29 cases,only 10 cases (34.5％) revealed specific etiology,including 7 cases of spinal vascular malformation,2 of tumor apoplexy,1 of cavernous hemangioma.After 2 weeks of conservative treatment,3 patients with grade D and 3 patients with grade E were assessed for spinal function.The average interval from onset to surgery was(9.4±7.5) days,the ASIA after two weeks of the operation was as follows:5 patients were assessed at grade A,5 patients at grade C,8 patients at grade D and 4 patients at grade E.28 patients were followed up for (48.7±23.1) months on average,6 patients without surgery were E,22 cases with surgery were as follows:4 cases A,18 cases D/E.Conclusions The etiology of spontaneous intraspinal hematoma is hard to define even after complete preoperative examination and exploratory operation.The preoperative neurologic functions are important predicting factors for the prognosis of spontaneous intraspinal hematoma.For patients who had neurologic function deficit,surgical treatment should be performed urgently to remove the hematoma and release the decompression of spinal cord.The majority of these patients can achieve a positive prognosis after surgery.
