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.

Modified arthroscopic Brostr?m procedure for the treatment of chronic ankle instability combined with multiple ligament laxity / 中华创伤杂志

Objective:To investigate the effectiveness of modified arthroscopic Brostr?m procedure for the treatment of chronic ankle instability combined with multiple ligament laxity.Methods:A retrospective case series study was used to analyze the clinical data of 26 patients with chronic ankle instability combined with multiple ligament laxity treated at Union Hospital, Tongji Medical College of Huazhong University of Science and Technology from January 2016 to December 2020, including 10 males and 16 females; aged 18-48 years [(27.5±7.1)years]. All patients underwent arthroscopic repair of the anterior talofibular ligament (ATFL) by the modified Brostr?m procedure. Healing of surgical incisions was observed after operation. The change of talus tilt angle for ankle stability evaluation, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score for ankle function evaluation, and the visual analogue score (VAS) for pain evaluation were assessed before operation, at 3 months postoperatively and at the last follow-up. Complications were observed.Results:All patients were followed up for 18-47 months [(25.3±8.5)months]. All surgical incisions were healed at stage I. The talus tilt angle was decreased from preoperative (15.6±4.7)° to (4.1±1.3)° and (3.5±0.9)° at 3 months postoperatively and at the last follow-up (all P<0.01). The AOFAS ankle-hindfoot score was improved from preoperative (65.8±14.5)points to (86.5±5.6)points and (93.4±4.2)points at 3 months postoperatively and at the final follow-up (all P<0.01). The VAS was decreased from preoperative 3.0 (2.0, 4.0)points to 1.5 (0.0, 2.0)points and 1.0 (0.0, 1.2)points at 3 months postoperatively and at the last follow-up (all P<0.01). Significantly higher AOFAS ankle-hindfoot score and lower VAS were found at the final follow-up when compared with the scores at 3 months postoperatively (all P<0.05). One patient developed superficial peroneal nerve injury, which was recovered spontaneously without special treatment. Conclusion:For chronic ankle instability combined with multiple ligament laxity, the modified arthroscopic Brostr?m procedure has advantages of improved ankle stability, good ankle function recovery, obvious pain relief and less postoperative complications.

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.

Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly (version 2023) / 中华创伤杂志

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Research Progress on the Protective Effect of Intestinal Flora on Radiation-induced Lung Injury in Thoracic Tumors / 中国肺癌杂志

Radiation therapy is one of the main treatment methods for patients with thoracic malignant tumors, which can effectively improve the survival rate of the patients. However, radiation therapy can also cause damage to normal tissues while treating tumors, leading to radiation-induced lung injury such as radiation pneumonia and pulmonary fibrosis. Radiation-induced lung injury is a complex pathophysiological process involving many factors, and its prevention and treatment is one of the difficult problems in the field of radiation medicine. Therefore, the search for sensitive predictors of radiation-induced lung injury can guide clinical radiotherapy and reduce the incidence of radiation-induced lung injury. With the in-depth study of intestinal flora, it can drive immune cells or metabolites to reach lung tissue through the circulatory system to play a role, and participate in the occurrence, development and treatment of lung diseases. At present, there are few studies on intestinal flora and radiation-induced lung injury. Therefore, this paper will comprehensively elaborate the interaction between intestinal flora and radiation-induced lung injury, so as to provide a new direction and strategy for studying the protective effect of intestinal flora on radiation-induced lung injury.

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.

Application of ERAS concept in treatment of tibial plateau fractures with minimally invasive double reverse tractions / 中华创伤骨科杂志

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.

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.

Mechanism and Research Progress of Microbiome in the Development of Lung Cancer / 中国肺癌杂志

Lung cancer is one of the most common malignant tumors with poor prognosis in China, and most patients are diagnosed as advanced patients. Studies have shown that the microecological characteristics of lung cancer patients are different from healthy people, and the microorganisms of the respiratory tract can affect the occurrence and development of lung cancer through various mechanisms. In recent years, the study of the correlation between microbiome and disease has become another research hotspot following the Human Genome Project. However, at present, there are relatively few studies on the characteristics of lung cancer and respiratory microbiome. Therefore, it is necessary to further explore the potential relationship between lung cancer and microbial flora. By studying the mechanism of action of respiratory microorganisms in the development of lung cancer, it is expected to provide a clearer scientific basis in the clinical diagnosis, treatment and prognosis assessment of lung cancer. This article reviews the current researches on microbial flora and lung cancer, and provides new ideas for clinical diagnosis and treatment of lung cancer.

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.
