As the National Health Commission changes the management of novel corona virus infection, the situation and preventive policies for controlling the epidemic have also entered a new stage in China. Perioperative care strategies for orthopedic trauma such as designated isolation and nucleic acid test screening have also been adjusted in the new stage. Based on the perioperative work experiences in the new stage of epidemic from the frontline anti-epidemic staff of orthopedics in domestic hospitals and combined with the literature and relevant evidence-based medical data in perioperative care of orthopedic trauma patients under the current anti-epidemic policies at home and abroad, Chinese Orthopedic Association and Chinese Society of Traumatology organized relevant experts to formulate the Guideline for clinical perioperative care of orthopedic trauma patients in the new stage of novel corona virus infection ( version 2023). The guideline summarized 16 recommendations from the aspects of preoperative diagnosis and treatment, infection prevention, emergency operation and postoperative management to systematically standardize the perioperative clinical pathways, diagnosis and treatment processes of orthopedic trauma in the new stage of novel corona virus infection, so as to provide a guidance and reference for hospitals at all levels to carry out relevant work in current epidemic control policies.

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.

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.

Objective:To evaluate the application of ERAS concept in the treatment of tibial plateau fractures with minimally invasive double reverse tractions (MIDRT).Methods:A retrospective study was conducted of the 39 patients with tibial plateau fracture who had been treated at Department of Orthopedics, Union Hospital from February 2018 to June 2020. They were 20 males and 19 females, aged from 27 to 47 years. All cases were treated with the same MIDRT but with different perioperative management protocols. Of them, 20 received conventional perioperative management (control group) and 19 perioperative ERAS management (ERAS group). The 2 groups was compared in terms of visual analogue scale (VAS) at 24 hours postoperation, drainage volume, time for removal of drainage tube, hospital stay, patient’s satisfaction, incidence of complications, and American Special Surgery Hospital (HSS) scores at discharge and 1, 3, 6 and 9 months postoperation.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability between groups ( P>0.05). All cases obtained complete follow-up (mean, 10.9 months). No statistically significant difference was found between the 2 groups in drainage volume, time for removal of drainage tube or HSS scores at discharge or one month after discharge ( P>0.05). The VAS score at 24 hours after operation, hospital stay [(9.4±4.8) d], patient's satisfaction, HSS scores [(90.8±3.8), (93.5±4.3) and (95.6±3.7)] in the ERAS group were significantly better than those in the control group [(13.3±1.9) d, (87.5±5.1), (88.1±4.4) and (88.8±4.4)] ( P<0.05). None of the patients had such serious complications as wound infection, breakage or failure of internal fixation, or fracture nonunion. Conclusion:The perioperative management protocols designed according to the ERAS concept may enhance the clinical efficacy of MIDRT in the treatment of tibial plateau fractures and thus raise the patient’s satisfaction.

Since December 2019, novel coronavirus pneumonia (NCP) has been reported in Wuhan, Hubei Province, and spreads rapidly to all through Hubei Province and even to the whole country. The virus is 2019 novel coronavirus (2019-nCoV), never been seen previously in human, but all the population is generally susceptible. The virus spreads through many ways and is highly infectious, which brings great difficulties to the prevention and control of NCP. Based on the needs of orthopedic trauma patients for emergency surgery and review of the latest NCP diagnosis and treatment strategy and the latest principles and principles of evidence-based medicine in traumatic orthopedics, the authors put forward this expert consensus to systematically standardize the clinical pathway and protective measures of emergency surgery for orthopedic trauma patients during prevention and control of NCP and provide reference for the emergency surgical treatment of orthopedic trauma patients in hospitals at all levels.

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 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.

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 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 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.
