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.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To investigate the classification of main pancreatic duct and treatment strategy after linear stapler closure of pancreatic neck in laparoscopic pancreaticoduodenectomy (LPD).Methods:The records of 51 consecutive patients with LPD who were treated by linear staple closure technique of pancreatic neck from February to December 2022 from Binzhou Second People′s Hospital, Shijingshan Campus, Beijing Chaoyang Hospital, Capital Medical University, Rizhao Hepatobiliary-Pancreatic-Splenic Surgery Research Institute, Chaoyang Central Hospital, Shandong Juxian People′s Hospital, Weihai Municipal Hospital, Binzhou Central Hospital, and Affiliated Hospital of Chifeng University were retrospectively reviewed. According to the visibility, position and diameter of the main pancreatic duct at the stump of the pancreas, the type of main pancreatic duct was divided into type I, type Ⅱ, type Ⅲa and type Ⅲb. The number of cases in each main pancreatic duct classification and the corresponding treatment strategies were examined.Results:A total of 51 cases of LPD were successfully completed. Of these patients, the males comprised 56.9%(29/51), and females comprised 43.1%(22/51), with age ranging from 31 to 88 years old. The type of the main pancreatic duct at the stump of the pancreas included 7 cases (13.7%) of type Ⅰ, 39 cases (76.5%) of type Ⅱ, 2 cases (3.9%) of type Ⅲa, and 3 cases (5.9%) of type Ⅲb. Corresponding treatment strategies were adopted according to different main pancreatic duct types, the main pancreatic duct was successfully found, and a support drainage tube was inserted.Conclusion:After linear stapler closure of pancreatic neck, corresponding treatment strategies should be adopted according to the classification of the main pancreatic duct, which would help to improve the success rate of finding the main pancreatic duct and placing a support drainage tube.

Objective:To investigate the clinical effect of local perforator advancement flap in repairing mid-face soft tissue defects and its correlation between with the three dimensional configuration of the skin ligament.Methods:1) 12 fresh adult cadaver specimens (7 males, 5 females, aged 54-87 years) were selected. After dehydration and degreasing of the cadaver head with acetone, plasticized and sliced with a fully transparent ultra-thin layer of epoxy resin, using a Leica MZ8 stereo microscope and a Leica DFC295 digital camera to observe and analyze the prepared slices, and observe the differences in the three-dimensional structural characteristics of the cutaneous ligaments in different parts of the midface (cheek, nose, orbital eyelid) . (2) A retrospective analysis was made of the case data of midface soft tissue defects admitted to the Plastic Surgery Department of the First Affiliated Hospital of Anhui Medical University from January 2015 to October 2021. All patients were repaired with local perforator advancement flap. The Pearson bivariate correlation test was used to analyze the correlation among flap advancement distance, flap area, flap aspect ratio, and defect size. The Kruskal-Wallis test was used to analyze the differences of flap area and flap aspect ratio in different parts of the midface.Results:1) Anatomical studies have shown that the running direction of the facial skin ligaments is the same as that of the expressive muscles, and their three-dimensional structures at the upper eyelid and the nasal and facial corners of the upper nasal alar are different. The upper eyelid skin ligaments run along the eyelid, while the upper nasal The supracutaneous ligaments run down the alar of the nose. (2) The clinical study included 18 patients, 8 males and 10 females, aged (65.1±22.9) years. The flaps of 18 patients survived after operation, the flap area was (13.85±9.38) cm 2, and the advancing distance was (1.94±0.75) cm. Statistical analysis showed that there was a correlation between the flap advancement distance and the flap incision area ( r=-0.712, P=0.022) and the flap aspect ratio ( r=-0.580, P =0.012). There was no correlation with the defect area ( r=-0.227, P=0.365) ; the aspect ratios of the cheek, nose and orbital lid flaps were 2.06±0.42 , 2.50±1.18, 3.25±0.93, and the differences were statistically significant ( H= 6.59, P=0.037). Conclusions:The local perforator advancement flap is an ideal method for repairing midface soft tissue defects. The differences in the construction of the skin ligaments in different parts of the mid-face will affect the ease of advancement of the flaps and other characteristics in each part, which may be the reasons for affecting the aspect ratio of the flap design.
