RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
Traumatic rib fractures are the most common injury in thoracic trauma. Previously，the patients with traumatic rib fractures were mostly treated non-surgically，of which 50%，especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities，being unable to retain a full-time job. In the past two decades，thanks to the development of internal fixation material technology，the surgical treatment of rib fractures has achieved good outcomes. However，there are still some problems in clinical treatment，including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans，and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore，the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association，in conjunction with national multidisciplinary experts，formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures（2021）following the principle of evidence-based medicine，scientific nature and practicality. This expert consensus puts forward some clear，applicable，and graded recommendations from aspects of preoperative imaging evaluation，surgical indications，timing of surgery，surgical methods，rib fracture sites for surgical fixation，internal fixation methods and material selections，treatment of combined injuries in rib fractures，in order to provide references for surgical treatment of traumatic rib fractures.
RESUMEN
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.
RESUMEN
Objective:Traumatic heterotopic ossification is the formation of extra-skeletal bone within soft tissues or joints after trauma. Injury factors induce many types of precursor cells to participate in this process. Many cytokines such as bone morphogenetic proteins, hypoxia inducible factor 1-α, inflammation factors and fibrin, can influence this process. Formation of heterotopic ossification often leads to the limitation of limb function and pain. However, prevention and treatment of heterotopic ossification often lead to bone nonunion and high recurrence rate. To find a treatment that can inhibit the formation of heterotopic ossification without affecting fracture healing has become a concern of clinicians. It is necessary to explore the formation mechanism of heterotopic ossification and find effective and safe methods. The authors document the cellular and molecular mechanisms involved in formation of traumatic heterotopic ossification for better understanding the factors affecting the formation of heterotopic ossification so as to provide references for new treatment methods.
RESUMEN
Neurologic heterotopic ossification (NHO) is a pathological phenomenon that involves the formation of ectopic bone in soft tissues, which is associated with central nervous system injury. NHO may cause severe complications such as disorder of limb's activity, severe pain, and skin ulcer. The pathogenesis of NHO is not clear. In the past decades, there's better understanding of NHO pathogenesis, and potential predictive and therapeutic targets were found. The authors overview the NHO pathogenesis based on osteogenic factors, osteogenic precursor cells and microenvironments, soas to provide references for clinical diagnosis and treatment.
RESUMEN
Objective:To evaluate the trauma center model in general hospitals for patients with severe trauma.Methods:The data of 1,248 patients with severe trauma (ISS≥16) were retrospectively analyzed who had been admitted to the trauma centers in 6 Chinese general hospitals from January 2019 through June 2020. They were 987 males and 261 females with an age of 50.4 years ± 15.4 years. Their injuries were caused by a traffic accident in 622 cases, falling from a height in 357 cases, a knife in 62 cases, and others (like a heavy object and fall) in 207 cases. Upon admission, their injury severity scores (ISS) were 24.9±8.5 and their Glasgow coma scores (GCS) 12.6±3.6. They were all treated in a scientific and standard manner by a multidisciplinary team at the trauma center of their specific general hospital. Recorded were deaths within 30 days after admission, 30-day mortality and causes of death.Results:All the patients were treated effectively. 101 deaths occurred within 30 days after admission, yielding a 30-day mortality of 8.1%. The main causes of death were severe craniocerebral injury in 56 cases, hemorrhagic shock in 26 cases, multi-organ failure in 11 cases and others in 8 cases.Conclusions:Establishment of trauma centers in China can make up for the disadvantage of over-division of clinical specialties in large general hospitals which has led to insufficient care for patients with severe trauma and multiple injuries. The trauma centers in general hospitals may be a feasible model to be popularized in treatment of patients with severe trauma and multiple injuries.
RESUMEN
Objective:To establish a rat model of volume-controlled hemorrhage and observe the pathophysiological changes that ensued.Methods:Sprague Dawley (SD) rats were subjected to femoral arterial cannulation and hemorrhage for 40% or 50% of total volume. The hemodynamics data and arterial blood gas were collected, and survival after hemorrhage was monitored for 24 hours ( n=8/group). Then lung, liver, intestine and kidney were collected for HE staining after 40% hemorrhage at 4, 8 and 12 hours ( n=6/group). Results:Mean arterial pressure of 40% and 50% blood loss group decreased significantly from (90±5)mmHg and (93±4)mmHg to (40±4)mmHg and (34±4)mmHg ( P<0.05). Heart rate of 40% and 50% blood loss group increased significantly from (330±35) bpm and (336±32) bpm to (478±36) bpm and (490±21) bpm ( P<0.05). Hemoglobin and pH decreased significantly following hemorrhage, while lactate increased. The survival rate of 50% blood loss group was just 12.5% and 40% blood loss group was 100% ( P<0.05). Compared with sham group, the most significant injury was observed in lung and small intestine after 4 hours, in liver after 8 hours and in kidney after 12 hours following hemorrhage. Conclusion:This study established a stable and repeatable volume-controlled hemorrhagic shock model in rat.

RESUMEN
Objective@#To observe operative results of tibiotalocalcaneal arthrodesis (TTC) via lateral transfibular ap-proach in the treatment of severe ankle and subtalar diseases.@*Methods@#Eighteen patients treated with TTC via lateral transfibu-lar approach from January 2015 to December 2017 were retrospectively analyzed. There were 11 males and 7 females from 39 to 76 years old, with an average age of 53.4 years. Preoperative diagnoses included traumatic arthritis (3 cases), osteoarthritis (10 cas-es), talar necrosis (3 cases), failure of ankle fusion (1 case) and Charcot-Marie-Tooth disease (1 case). Ankle and hindfoot deformi-ty included varus (10 cases), valgus (6 cases), equinus (1 case) and equinovarus (1 case). All cases were classified into stage-3 ar-thritis according to Morrey-Wiedeman classification. All patients sustained pain and stiffness in the ankle and hindfoot as well as walking dysfunction. Preoperative and 1 year postoperative visual analogue scale (VAS) and American Orthopaedic Foot and An-kle Society (AOFAS) ankle-hindfoot scale were collected. Postoperative joint fusion and complications were observed.@*Results@#Follow-up ranged from 12-47 months, averaging 25.4 months. Preoperative VAS scores were 6-9, averaging 7.1±1.0, while postop-erative VAS scores at 1 year follow-up were 0-2, averaging 0.9±0.8, which decreased significantly. Preoperative AOFAS scores were 24-59, averaging 40.6±11.5, while postoperative AOFAS scores at 1 year follow-up were 68-84, averaging 75.3±5.8, which increased significantly. 8 cases were good and 10 cases were fair according to AOFAS scores at 1 year follow-up. The excellent and good rate was 44.4% (8/18). All joints were fused successfully without implants loosening or breakage. All patients satisfied with operative results at 1 year follow-up. Lateral distal wound dehiscence happened in 1 case of traumatic arthritis and the wound was finally healed after debridement and vacuum assisted closure (VAC). Two cases of osteoarthritis presented with dorsal lateral foot numbness and became asymptomatic after neurotrophic medication. One case of osteoarthritis complained of discomfort in the lateral heel caused by implants prominence and implants were removed at 1 year after surgery. Postoperative complication rate was 22.2% (4/18) .@*Conclusion@#TTC via lateral transfibular approach with cannulated screws and locking plate system is safe and ef-fective. Joint fusion rate is high and complication rate is low. During operation, attention should be paid to restoring hindfoot align-ment, soft tissue balance, proper bone graft and joint compression.

RESUMEN
Objective To verify the effectiveness of a self-designed preoperative risk scoring system for elderly patients with hip fracture.Methods A total of 286 elderly patients with hip fracture were included for this prospective study who had been admitted from February 1,2014 to February 1,2016 to Department of Trauma and Orthopedics,Peking University People's Hospital.They were divided into 5 groups according to their scores by our self-designed preoperative risk scoring system for elderly patients with hip fracture:0 to 10 points,11 to 20 points,21 to 30 points,31 to 40 points and above 41 points.Postoperative complications and deaths were recorded.The correlations between their preoperative scores and postoperative medical complications or death were analyzed to verify the effectiveness of the preoperative risk scoring system for elderly patients with hip fracture.Results The 286 patients scored 24.9 ± 11.0 (from 0 to 69) preoperatively.The femoral neck fractures scored 24.0±11.0 and femoral intertrochanteric fractures 26.3±10.8.The incidence of medical complications was 4.00％ (1/25) in the 0 to 10 points group,4.17％ (3/72) in the 11 to 20 points group,14.66％ (17/116) in the 21 to 30 points group,23.53％ (12/51) in the 31 to 40 points group and 50.00％ (11/22) in the above 41 pints group.Conclusion As the incidence of postoperative medical complications in elderly patients with hip fracture is positively correlated with the scores by our self-designed preoperative risk scoring system for elderly patients with hip fracture,the preoperative risk scoring system can provide an effective prediction of surgical risks.
RESUMEN
Objective To evaluate the efficacy of a modified risk scoring system in predicting the mortality during hospitalization in the elderly patients undergoing hip fracture surgery.Methods At the first stage,we retrospectively analyzed the clinical data of 1,562 elderly patients with hip fracture who had been admitted to Department of Trauma and Orthopedics,Peking University People's Hospital from January 2010 to December 2014.A multi-factor risk-adjustment model for surgical risks was constructed by multi-variate logistic regression analysis to obtain a modified preoperative risk scoring system for elderly patients undergoing hip fracture.At the second stage,a cohort of 1,356 elderly patients with hip fracture from January 2015 to December 2018 was included for a prospective evaluation of the modified risk scoring system.The patients included were divided into 5 groups according to their scores:a very low risk group of 0 to 10 points,a low risk group of 11 to 20 points,a moderate risk group of 21 to 30 points,a high risk group of 31 to 40 points and a very high risk group of ≥41 points.The consistency between the scores and the actual outcomes of the patients was observed and the receiver operating characteristic curve (ROC) was drawn accordingly.Results The 1,356 cases included in the study scored 25.12 ± 10.30 points (from 0 to 67 points).The in-hospital mortality was 0％ (0/96) in the very low risk group,0.23％ (1/443) in the low risk group,0.49％ (2/409) in the moderate risk group,2.16％ (6/278) in the high risk group,and 5.38％ (7/130) in the very high risk group.The area under the ROC curve was 0.825 (95％ CI:0.728-0.921,P ＜ 0.01).Conclusions As the in-hospital mortality is positively correlated with the scores of the modified preoperative risk scoring system for elderly patients undergoing hip fracture,the modified scoring system can be used to predict the in-hospital morbidity of the patients.The modified scoring system can be further verified and calibrated by multi-center clinical evaluation.
RESUMEN
Objective To establish a preoperative risk scoring system for elderly patients with hip fracture on the basis of investigation into the factors influencing their mortality during hospitalization. Methods The data were collected from the database of hospitalization summary reports ( HSR ) of Beijing Public Health Commission concerning the 14, 577 patients who had been 55 years old or older and hospitalized for hip fracture from January 1, 2006 throughout December 31, 2010 at the 35 top-rank hospitals in Beijing. They were divided into a surgery group and a non-surgery group. Two multivariable risk-adjustment models were established for the 2 groups on the basis of an investigation into the factors influencing their mor-tality during hospitalization. Finally a preoperative risk scoring system for elderly patients with hip frac-ture was formulated according to the valuation of the least common multiples of β coefficients of the risk factors.Results Besides senior age and male gender, 10 different comorbidities were independently associated with in-hospital mortality, particularly pulmonary embolism, respiratory failure, renal failure and diabetes. The risk for inpatient mortality associated with a specific comorbidity was relatively higher in the surgery group than in the non-surgery group. The risk-adjustment models based on the variables had better accuracy in predicting in-hospital mortality ( ROC＝0.91 in surgery group versus ROC＝0.85 in non-surgery group ). In our preoperative risk scoring system for elderly patients with hip fracture, 10 points were for an age of 65 to 74 years old, 14 points for an age of 75 to 84 years old, 18 points for an age beyond 85 years old, 4 points for male gender, 20 points for pulmonary embolism, 18 points for respiratory failure, 10 points for renal insufficiency, 8 points for diabetes, 8 points for heart failure, 7 points for malignant tumor, 7 points for lung infection, 7 points for disturbance of water, electrolyte and acid-base balance, 6 points for arrhythmia, and 6 points for cerebral infarction, totaling 119 points. Conclusions The primary risk factors for in-hospital mortality in the elderly patients with hip fracture seem to be senior age, male gender and 10 different comorbidi-ties. A preoperative risk scoring system has been successfully established for elderly patients with hip fracture.
RESUMEN
Objective To observe operative results of 2 posteromedial approaches in the treatment of posterior pilon fractures of Klammer type Ⅲ.Methods From January 2015 to December 2016,19 patients with posterior pilon fracture (Klammer type Ⅲ) were treated via the posteromedial approach.They were 12 men and 7 women,aged from 21 to 61 years (mean,37.4 years).Straight posteromedial incision was used in 11 cases and curved posteromedial incision in the other 8 cases.The 2 groups were compared in terms of postoperative wound complication,infection,bone union,visual analogue scale (VAS) and American Orthopedic Foot and Ankle Society (AOFAS) scores.Results Follow-up ranged from 6 to 29 months (mean,11.8 months).All the fractures united after 6 to 15 months (mean,10.7 months).In the straight incision group,the VAS scores at the final follow-up ranged from 0 to 3 points,averaging 1.1 points;the AOFAS scores ranged from 83 to 100 points,averaging 90.8 points.In the curved incision group,the VAS scores at the final follow-up ranged from 0 to 3 points,averaging 1.3 points;the AOFAS scores ranged from 80 to 100 points,averaging 90.1 points.In one case in the curved incision group,the posteromedial wound failed to heal but scar healing was achieved after dressing change for 4 months.Conclusion The posteromedial approach,whether straight or curved,can provide good exposure for posterior pilon fractures of Klammer type Ⅲ,which is conductive to reduction and fixation of the fracture.
