Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective:To investigate the relationship between resilience, perceived social support, and adaptability in military freshmen.Methods:A total of 195 freshmen were randomly selected from a military medical university. The Chinese version of Connor-Davidson Resilience Scale (CD-RISC), the Perceived Social Support Scale (PSSS), and a self-test questionnaire of college students' psychological adaptability were used to investigate their resilience, perceived social support, and adaptability. SPSS 26.0 was used to perform an independent samples t-test and a Pearson correlation analysis to analyze the differences in these scores between freshmen with different demographic characteristics and the correlation between these scores. By using the PROCESS plug-in, a structural equation model was used to analyze the mediating effect of resilience on the relationship between social support and psychological adaptation, which was further tested using the Bootstrap method. Results:The independent samples t-test showed that females had a significantly higher score of other support than males ( t = -2.05, P = 0.041), and student leaders had significantly higher scores of family support and other support, total score of social support, and score in psychological adaptability than other students (all P<0.05). The correlation analysis showed that there were significant positive correlations between the scores of PSSS and its each item, CD-RISC, and self-test of college students' psychological adaptability (all P<0.05). The structural equation model showed that resilience partially mediated the relationship between social support and psychological adaptation, and the Bootstrap method revealed a significant indirect effect (95%CI: 0.102-0.253). Conclusion:Resilience plays a partial mediating role between perceived social support and adaptability in military freshmen. They should be guided to correctly perceive external support and develop strong resilience.

Objective:To evaluate the effect of preoperative cognitive behavioral therapy (CBT) on pain catastrophizing in the patients with orthopedic trauma.Methods:A total of 120 patients with lower extremity bone trauma, aged 18-64 yr, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, with body mass index of 18-28 kg/m 2, with Pain Catastrophic Scale (PCS) score on admission >16, scheduled for surgical treatment, were enrolled.The patients were divided into 2 groups ( n=60 each) by the stratified randomization method based on the type of fracture: CBT group and routine group (group R). Group CBT received CBT for pain through the internet on the day of admission and one day before operation.The patients in both groups underwent reduction and internal fixation of lower extremity fractures under combined spinal-epidural anesthesia.The PCS scores were recorded immediately after admission and on the morning of the operation day.The effective pressing times of the patient-controlled analgesia pump, consumption of analgesics for rescue analgesia, and occurrence of nausea and vomiting within 48 h after operation were recorded.The visual analogue scale score of the surgical site during activity and occurrence of the score >3 at 3 months after operation and use of opioids within 3 months after operation were recorded. Results:Compared with group R, the PCS score was significantly decreased on the morning of the operation day, the pressing times of the patient-controlled analgesia pump, consumption of analgesics for rescue analgesia and incidence of nausea and vomiting within 48 h after operation were decreased, the requirement for opioids within 3 months after operation was decreased ( P<0.05), and no significant change was found in VAS score during activity and occurrence of the score >3 at 3 months after operation in group CBT ( P>0.05). Conclusions:Preoperative CBT can reduce the degree of pain catastrophizing and is helpful in increasing the quality of postoperative analgesia in the patients with orthopedic trauma.
