Objective To explore the clinical outcomes of treating unstable intertrochanteric fractures with proximal femoral locking plate (PFLP) in the elderly patients.Methods From January 2010 to June 2015,380 elderly patients with unstable intertrochanteric fracture were treated with PFLP and successfully followed up at our department.They were 171 men and 209 women,from 60 to 89 years of age (average,68.7 years).By AO classification,there were 58 cases of AO31-A2.2,87 ones of 31-A2.3,130 ones of 31-A3.1,63 ones of 31-A3.2,and 42 ones of 31-A3.3.Operation time,incision length,length of hospital stay,fracture healing time,postoperative complications and hip joint Harris scores were recorded.Results This cohort was followed up for an average of 13.3 months (range,from 8 to 21 months).Their operation time averaged 53.2 min,X-ray exposure 12.2 times,intraoperative blood loss 92.7 mL,incision length 12.6 cm,postoperative drainage volume 54.7 mL,and length of hospital stay 9.2 days.Pulmonary infection was observed in 3 cases,fixation loosening in 8,fixation breakage in 2,hip varus in 9,and fracture nonunion in 4,yielding a total complication rate of 6.8％ (26/380).No operative incision infection was observed.The average fracture healing time was 11.8 weeks (range,from 7 to 48 weeks) after operation.The average Harris score one year postoperation for the 380 patients was 86.3 ± 6.1,significantly higher than the preoperative value (43.6±4.4) (P ＜0.05).There were 96 excellent,231 good,42 fair and 11 poor cases,giving an excellent to good rate of 86.1％.Conclusion Since PFLP has advantages of limited invasion,blood loss and complications,a high rate of fracture healing,and good functional recovery of the hip,it may be a good treatment for unstable intertrochanteric fractures in the elderly patients.

Objective To explore the efficacy of proximal femur locking plate(PFLP) for the treatment of unstable femoral intertrochanteric fractures in elderly patients.Methods Data of 120 cases of patients with unstable femoral intertrochanteric fractures who were treated by PFLP were retrospectively analyzed.There were 56 males and 64 were females,aging from 62 to 78 year-old (average,69.4 year-old).85 cases were left hip,and 35 cases right hip.According to AO fracture classification,there were 12 cases of A2.2,23 A2.3,34 A3.1,29 A3.2,and 22 A3.3.According to Evans intertrochanteric fractures classification:there were 93 cases of type Ⅲ,19 type Ⅳ,and 8 type Ⅴ.Operation time,length of hospital stay,fracture healing time,postoperative complications and hip joint Harris scores were recorded.Results All patients were followed up for 8-14 months (average,12.4 months).Their operating time were 51-80 min (average,63.1 min);X-ray exposure were 8-15 times (average,11.6 times);intraoperative blood loss were 70-120 ml (average,92.7 ml);postoperative drainage volume were 50-100 ml (average,61.7 ml),and length of hospital stay were 7-14 d (average,10.2 days).The healing time ranged from 12 to 32 weeks (20.4 weeks average).14 cases had delayed union,and healing time was 8-10 months.In addition,4 cases had deep vein thrombosis (after thrombolysis therapy the vein was recanalized);2 had internal fixation broken,who were then treated with PFNA Ⅱ,and bone healed after 6 months;5 had hip varus,who were then treated via hip replacement,and no hip prosthesis fracture were found.No other complications occurred in the remaining patients.At the latest follow-up,according to Harris hip score:there were 38 cases with excellent results,71 good,9 fair,and 2 poor,and the rate of excellent and good was 90.8％ (109/120).Conclusion PFLP for the treatment of unstable femoral intertrochanteric fractures has advantages of less invasion,less complication,reliable fixation and high fracture healing rate,thus it is suitable for unstable intertrochanteric fractures in elderly patients.

Objective To analyze the related factors of femoral head necrosis after internal fixation operation of femoral neck fracture.Methods Clinical data of 524 patients with femoral neck fracture who underwent internal fixation surgery between January 2012 and January 2015 were retrospectively analyzed.Taking the femoral head necrosis as an observable indicator,the clinical data of postoperative femoral head necrosis and those other patients who were treated at the same period were compared.Whether the clinical factors (gender,age,surgical reduction type,fracture type,quality of reduction,post-injury operation time,loading time after operation,and whether to withdraw internal fixation) were in correlation with postoperative femoral head necrosis was analyzed by univariate analysis.Then the statistically significant indicators were integrated into logistic regression analysis to determine the related factors of femoral head necrosis.Results According to inclusion and exclusion criteria,the study group consisted of 212 cases,including 94 males and 118 females;the follow-up time was 2-5 years,and the average follow-up time was 3.6±1.6 years.There were 46 cases with femoral head necrosis and 166 cases without femoral head necrosis after operation.The rate of femoral head necrosis was 21.7％ (46/212).The femoral head necrosis group included 46 cases with 21 males and 25 females;20 cases below 60 years old and 26 cases above 60 years old;17 cases using open reduction and 29 cases using closed reduction;6 cases belong to type Ⅰ/Ⅱ and 40 cases belong to type Ⅲ/Ⅳ according to Garden classification;16 cases got satisfactory reduction while 30 cases with unsatisfactory reduction;30 cases below 48 h and 16 cases above 48 h on post-injury operation time;17 cases below 3 months and 29 cases above 3 months on post-operation loading time;22 cases with internal fixation removal and 24 cases without internal fixation removal.The femoral head without necrosis group included 166 cases with 73 males and 93 females;84 cases below 60 years old and 82 cases above 60 years old;69 cases using open reduction and 98 cases using closed reduction;120 cases belong to type Ⅰ/Ⅱ and 46 cases belong to type Ⅲ/Ⅳ according to Garden classification;160 cases got satisfactory reduction while 6 cases with unsatisfactory reduction;119 cases below 48 h and 47 cases above 48 h on post-injury operation time;70 cases below 3 months and 96 cases above 3 months on post-operation loading time;74 cases with internal fixation removal and 92 cases without internal fixation removal.Univariate x2 analysis suggested that fracture type and quality of reduction were associated with postoperative femoral head necrosis.Other clinical factors (gender,age,surgical reduction type,post-injury operation time,loading time after operation and whether to remove internal fixation or not) were not associated with postoperative femoral head necrosis.The multivariate Logistic regression analysis showed fracture type and quality of reduction were significantly related to postoperative femoral head necrosis.Conclusion Femoral head necrosis after internal fixation operation of femoral neck fracture is affected by many factors.The fracture type and quality of reduction are important factors affecting femoral head necrosis after internal fixation operation of femoral neck fracture.

Objective To investigate the advantage and application prospect of 3D printing technology in assisting surgery for complex tibial plateau fractures.Methods The complete clinical data of 41 patients (48 knees) were retrospectively analyzed.And these patients were divided into two groups as 3D printing assisted operation group and traditional operation group,according to whether 3D printing technology was applied.Study was carried out to compare the clinical efficacy of surgery assisted by 3D printing technology and traditional surgery in the treatment of complex tibial plateau fractures.The 3D printing assisted operation group included 18 patients (22 knees,12 males and 6 females),aging from 16 to 68 (mean age 45.5±7.2),and there were 12 cases of Schatzker Ⅴ and 10 Ⅵ.The traditional operation group included 23 patients (26 knees,15 males and 8 females),aging from 19 to 69 (mean age,46.2±6.8),and there were 14 cases of Schatzker Ⅴ and 12 Ⅵ.The operation time,intraoperative blood loss,the Rasmussen score and hospital for special surgery knee score (HSS) at 6 weeks post-operation were analyzed and the difference between the two groups was tested.Results All those patients were followed up for 7 to 20 months (mean 15 months).For 3D printing assisted operation group,the mean operation time was 81.4±6.3 min for Schatzker Ⅴ and 90.6± 15.4 min for Schatzker Ⅵ;the mean intraoperative blood loss was 200.4±72.3 ml for Schatzker Ⅴ and 280.6±101.6 ml for Schatzker Ⅵ;the result of 6-week Rasmussen score was 14 excellent,6 good and 2 fair (excellent and good rate 90.9％);the result of 6-week HSS score was 15 excellent,5 good and 2 fair (excellent and good rate 90.9％).Then for traditional operation group,the mean operation time was 100.4± 15.3 min for Schatzker Ⅴ and 111.5±20.2 min for Schatzker Ⅵ;the mean intraoperative blood loss was 450.4±173.3 ml for Schatzker Ⅴ and 500.5±247.2 ml for Schatzker Ⅵ;the result of 6-week Rasmussen score was 14 excellent,8 good,2 fair and 2 bad (excellent and good rate 84.6％);the result of 6-week HSS score was 13 excellent,8 good,2 fair and 3 bad (excellent and good rate 80.8％).The difference in operation time,intraoperative blood loss had statistical significance between the two groups;but the difference in 6-month post-operation Rasmussen score and HSS score had no statistical significance.Conclusion Compared with traditional surgery,3D printing technology assisted surgery for complex tibial plateau fracture possesses advantage such as shortened operation time,reduced intraoperative blood loss;but there's no evidence for improved knee function at 6 weeks post-operation.

OBJECTIVE:To evaluate the efficacy and safety of Yupingfeng powder combined with second- generation antihistamines versus second-generation antihistamines for chronic urticaria(CU)systematically,and to provide evidence-based reference for clinical treatment for CU. METHODS:Retrieved from PubMed,Embase,The Cochrane Library,CJFD,VIP and CBM,RCT about therapeutic efficacy(total response rate,cure rate,recurrence rate)and safety(the incidence of ADR)of Yupingfeng combined with second-generation antihistamines(trial group)versus second-generation antihistamines(control group) in the treatment of CU were collected. The data extraction was performed for included clinical studies,and Meta-analysis was performed by using Rev Man 5.3 statistical software after quality evaluation with Cochrane Handbook 5.1.0 evaluation criteria. RESULTS:A total of 34 RCTs were enrolled,involved 3 405 patients in total. Results of Meta-analysis showed that the total response rate [OR=4.02,95%CI(3.03,5.34),P<0.001],cure rate [OR=2.25,95%CI(1.95,2.60),P<0.001] and recurrence rate [OR=0.33,95%CI(0.26,0.42),P<0.001] of trial group were significantly better than those of control group,with statistical significance. There was no statistical significance in the incidence of ADR between 2 groups [OR=0.98,95%CI(0.71,1.37),P=0.92]. CONCLUSIONS:For CU therapy,Yupingfeng powder combined with second-generation antihistamines is better than second-generation antihistamines alone in improving total response rate and cure rate,reducing recurrence rate,both have similar safety.

Objective To investigate the clinical effect of phase Ⅰ debridement combined with antibiotic bone cement bead chain packing for chronic infection after fracture.Methods A retrospective case series study was carried out to analyze the clinical data of 50 patients with chronic bone infection admitted to Wuhan Union Hospital from February 2015 to June 2017.There were 38 males and 12 females,aged 28-70 years [(48.4 ± 5.1) years].In terms of the infection site,there were 36 patients at the humerus,seven at the femur,three at the phalanges,two at the calcaneus,and two at the spine.A total of 42 infection patients were reported after internal fixation,and eight infection patients were reported after fracture.All patients were treated with phase I debridement combined with antibiotic bone cement bead chain packing.The changes of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) before operation and 1,4 and 7 days after operation,infection control rate,number of debridement operations,bone healing time after bone grafting,and infection recurrence rate were recorded.Results The patients were followed up for 6-22 months [(12.4 ± 2.9) months].At postoperative 1,4 and 7 days,the preoperative ESR [(41.2 ± 5.3) mm/h] and preoperative CRP [(83.2 ± 9.3) mg/L] were decreased to (37.1 ± 4.8) mm/h,(32.5 ± 3.1) mm/h,(22.3 ± 1.9) mm/h and (71.1 ± 4.6)mg/L,(66.5 ± 3.1) mg//L,(39.3 ± 1.9) mg/L,respectively (P ＜ 0.05).The infection control rate was 94％ (47/50),and the number of debridement operations was 2-5 [(2.2 ± 0.3)].The bone healing time was 14-30 weeks [(24.6 ± 6.7) weeks],and the infection recurrence rate was 2％ (1/47).Conclusion Phase I debridement combined with antibiotic bone cement bead chain packing is an ideal method in treating chronic bone infection,with high infection control rate,low recurrence rate,and satisfactory bone union.

Objective To investigate the causes and treatment strategy for postoperative complications following trans-articular external fixation in the elder patients with distal radius fracture of type C3.Methods The clinical data were retrospectively studied of the 226 patients with distal radius fracture of type C3 who had been treated by trans-articular external fixation from January 2011 to December 2016 at Department of Orthopaedics,Union Hospital.Of them,42 (18.6％) suffered from postoperative complications.They were 12 men and 30 women,aged from 65 to 83 years (average,68.4 years).Results Of the 42 patients,22 (52.4％) had loss of reduction which was improved by timely adjustment of their external fixators,14 (33.3％) had joint stiffness which was mitigated by physical therapy,5 (11.9％) had traumatic arthritis which was relieved after medication and physical therapy,and one (2.4％) had pin tract infection which was controlled after antibiotic treatment and regular dressing change.Conclusion Although trans-articular external fixation is an effective treatment for elder patients with distal radius fracture of type C3,it is likely to result in a major complication,loss of reduction,which should be treated timely and effectively to avoid serious consequences.

Objective: To evaluate Herbert screwing directly via the anterior approach for femoral head fractures of Pipkin type Ⅱ in the youth. Methods: A retrospective analysis was conducted of the 16 patients who had been treated at Department of Orthopaedics, Union Hospital, Tongji Medical College for femoral head fractures of Pipkin type Ⅱ from August 2016 to June 2018. They were 9 men and 7 women, aged from 18 to 45 years (mean, 25.6 years). Of them, 10 cases who had been complicated with posterior dis-location of the hip received emergency hip reduction(<6 h) before surgical fixation. All the patients underwent Herbert screwing directly via the anterior approach. Their incision length, operation time, intraoperative blood loss, hospitalization time, Harris hip scores, therapeutic efficacy and complications were recorded. Results: In this series, the incision length averaged 10.4 cm, operation time 45.6 min, intraoperative blood loss 46.5 mL, and hospitalization time 4.0 d. All the 16 patients were followed up for 11 to 15 months (average, 12.7 months). Their Harris hip scores at preoperation, 3, 6 and 9 months postoperation and at the last follow-up were, respectively, 14.3±2.2, 64.8±2.4, 81.1±4.9, 88.1±4.6 and 91.9±3.4 points, showing a significant difference between any 2 time points (P<0.05). The therapeutic efficacy at the last follow-up by the Thompson-Epstein clinical evaluation was assessed as excellent in 9 cases, as good in 6 and as fair in one. No osteonecrosis of the femoral head or heterotopic ossification was observed by follow-up. Conclusion For young patients with femoral head fracture of Pipkin type Ⅱ, Herbert screwing directly via the anterior approach provides easy exposure and manipulation, does not aggravate the blood supply to the femoral head, decreases incidence of heterotopic ossification, and leads to shorter operation time and quick functional recovery of the hip.

Objective: To explore the clinical effect of bone grafting in the injured vertebrae combined with pedicle screw-rod system assisted with drugs in treating lumbar vertebral compression fracture in the elderly. Methods: A retrospective case-control study was carried out to analyze the clinical data of 48 cases of lumbar vertebral compression fracture in the elderly admitted to the Union Hospital between October 2015 and October 2018. There were 34 males and 14 females, aged 60-78 years [(62.8±2.5)years]. Segment of injury was L₁ in 37 cases, L₂ in 7, L₃ in 2, and L₄ in 4. There were 20 cases in bone grafting group involving 15 males and five females, aged from 60 to 78 years [(63.7±2.1)years]. There were 28 cases in non-bone grafting group involving 19 males and nine females, aged from 60 to 75 years [(62.4±2.9)years]. The Frankel scale in bone grafting group was grade D in 15 cases and grade E in 5, and in non-bone grafting group was grade D in 18 cases and grade E in 10. All the cases were treated by pedicle screw fixation combined with antiosteoporosis drugs, and the bone grafting group were treated by bone grafting via the injured vertebrae, but the other group were not. The intraoperative blood loss and operation time for each segmental vertebrae were recorded. The visual analogue scale (VAS) before operation and one year after operation, the bone healing at three months and one year postoperatively were recorded. The compression rate of the injured vertebrae at operation, at one day and one-year postoperatively as well as the height loss of the injured vertebrae at postoperative one year were measured. Spinal cord injury was also evaluated by Frankel scale. Wound healing, lower limb thrombosis, lung infection and ulcer were observed. Results: All the cases were followed up, with duration for 12-25 months [(16.2±3.4)months] in bone grafting group and 15-24 months [(17.5±5.4)months] in non-bone grafting group (P>0.05). The blood loss was (240±70)ml in bone grafting group and (210±65)ml in non-bone grafting group (P>0.05). Screw implantation time for each segment was (38.5±9.6)minutes in bone grafting group and (30.5±5.4)minutes in non-bone grafting group (P<0.05). The VAS was (7.5±1.8)points preoperatively and (1.5±0.7)points at one year postoperatively in bone grafting group, while (7.8±1.4)points and (2.9±1.2)points in non-bone grafting group, with significant difference between the two groups at one year postoperatively (P<0.05). The fracture healing rate was 85% (17/20) and 95% (19/20) at three months and one year postoperatively in bone grafting group, while 64%(18/28) and 86%(24/28) in non-bone grafting group, with no statistical difference between the two groups (P>0.05). No significant difference was found in compression rate of the injured vertebral height between the two groups before and after operation (P>0.05). The height loss rate of the injured vertebrae was 3% (2%, 4%) at one year postoperatively in bone grafting group and 6% (5%, 8%) in non-bone grafting group (P<0.05). The Frankel scale was all Grade E postoperatively. During the follow-up, no lower limb thrombosis, lung infection or ulcer occurred. One case had bone non-union in bone grafting group and four in non-bone grafting group (P>0.05). Conclusion For lumbar vertebral compression fracture in the elderly, bone grafting in the injured vertebrae combined with pedicle screw-rod system assisted with drugs is significantly better in recovering and maintaining the injured vertebrae height, relieving the pain and promoting the bone healing, although the screw implantation time is prolonged.

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.
