Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

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.

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 investigate the prevalence of depression of middle school students in Liaoning Province in 2019 and analyze its influencing factors, to provide corresponding strategies and measures for depression prevention and control. Methods: By using the method of multi-stage stratified random cluster sampling, the 32 909 students of grade 1-3 of junior middle school, senior high school and vocational high school were selected from 14 cities in Liaoning province, and were investigated with Center for Epidermiologic Studies Depression Scale (CES-D) psychological scale. Results: The depression score of middle school students in Liaoning Province was (12.66±9.53), and the incidence of depression was 19.5%. Analysis of variance and multiple regression analysis showed that the main factors influencing the occurrence of depression were grade, bullying on campus, internet addiction, being beaten and scolded by parents, drinking, gender, Leave of absence from school, smoking, serious injury and economic classification (P<0.05). Conclusion Depression of middle school students in Liaoning Province is not optimistic. Effective prevention and control measures should be developed and implemented to the occurrence of adverse factors, so as to reduce the occurrence of depression symptoms.

Objective To evaluate euthyphoria reduction combined with percutaneous iliosacral screw fixation in the treatment of irreducible sacroiliac dislocation.Methods From March 2012 to May 2015,29 patients with irreducible sacroiliac dislocation were treated using euthyphoria reduction followed by percutaneous iliosacral screw fixation.They were 18 men and 11 women,aged from 25 to 68 years (average,37.9 years).According to the Tile classification,there were 7 cases of type Cl,9 cases of type C2,and 13 cases of type C3.The intervals from injury to surgery ranged from 6 to 32 days (average,11.3 days).Results The operation time for this cohort ranged from 40 to 125 minutes (average,76.2 minutes).The intraoperative bleeding ranged from 50 to 360 mL (average,148.6 mL).Their follow-ups ranged from 24 to 41 months (average,28.9 months).According to the Matta criteria for reduction,20 cases were rated as excellent and 9 as good,yielding an excellent to good rate of 100％.Their Majeed scores at the final follow-up averaged 90.1 points (range,from 67 to 100 points),giving 20 excellent,7 good and 2 fair cases (with an excellent to good rate of 93.1％).No screw loosening or lameness of the affected limb was observed during follow-ups.Conclusions Euthyphoria reduction combined with percutaneous iliosacral screw fixation can lead to satisfactory outcomes in the treatment of irreducible sacroiliac dislocation.Additionally it may improve operative safety.

Objective The rate of post -operative complications has been increased with the changes in patients' age,prolonged duration, more severe and diffused lesions, and more patients with complications in recent years. We try to identify the risk factors associated with prolonged stay in the intensive care unit ( ICU ) after coronary artery bypass graft surgery (CABG). Methods 1623 patients who received CABG surgery in Beijing Anzhen Hospital Between June 1, 2006 and December 31,2007 were divided into two groups based on their stay duration in the ICU. Prolonged stay in ICU was defined as 5days or more. Univariate and multivariate analysis ( logistic regression) were used to identify the risk factors. The discrimination and calibration of the result were tested after the risk factors were determined. Results Fifty one patients had prolonged ICU stay, accounting for 3.14% of total cases. Multivariate logistic analysis showed that the age of patients, peripheral vascular diseases, critical status before operation, LVEF, operative status, mitral regurgitation, postoperative respiratory failure,postoperative renal failure, secondary thoracotomy for postoperative bleeding were associated risk factors. Conclusion Prolonged ICU stay after CABG surgery can be predicted based on the above factors. For patients with these risk factors, more pre-and postoperative care strategies are needed.
