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.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

BACKGROUND:Lumbar decompression and fusion is the most effective surgical method to treat lumbar degenerative spondylolisthesis.In recent years,the sagittal balance of the spine has been widely considered the key factor to adjust the outcome of spinal surgery,and factors that can affect the sagittal balance of the spine indirectly affect the surgical effect and prognosis. OBJECTIVE:To summarize the risk factors that can affect the sagittal balance of the spine during decompression and fusion due to lumbar spondylolisthesis,and play a certain reference role in the surgical treatment of lumbar spondylolisthesis. METHODS:With"lumbar spondylolisthesis,the sagittal plane balance of the spine,surgical treatment,risk factors"as the Chinese search terms,and"lumbar spondylolisthesis,sagittal balance,risk factor"as the English search terms,PubMed,Springer,ScienceDirect,Wanfang,VIP and CNKI were searched respectively.The focus of the search was from January 2010 to January 2023,and a few classic long-term articles were included.Preliminary screening was conducted by reading the title and abstract.After excluding repetitive research in Chinese and English literature,low-quality journals and irrelevant literature,67 articles were finally included for review. RESULTS AND CONCLUSION:(1)Degenerative lumbar spondylolisthesis is an important factor causing spinal canal stenosis and lumbar instability,and is the main cause of low back pain and intermittent claudication.Lumbar decompression,fusion and internal fixation is an effective way to treat degenerative lumbar spondylolisthesis.(2)In the past,the treatment of degenerative lumbar spondylolisthesis with decompression,fusion and fixation focused on thorough exploration and release of nerve roots,reduction of spondylolisthesis and solid internal fixation,but less attention was paid to the balance of sagittal plane of the spine.(3)With the popularization of lumbar decompression,fusion and internal fixation,complications caused by the sagittal imbalance of the spine gradually increased,resulting in poor prognosis of patients and even increased risk of secondary surgery.(4)Previous studies have only discussed the correlation between lumbar sagittal plane parameters and spinal sagittal plane balance,but have not in-depth studied the relevant factors causing spinal sagittal plane imbalance.(5)Our results show that open lumbar fixation and fusion,complete reduction of spondylolisthesis,selection of thicker pedicle screws,selection of larger fusion cages,and autologous bone transplantation are beneficial factors for maintaining sagittal balance.The higher the number of fusion segments,the higher the level of fusion segments is,which is a risk factor for sagittal plane imbalance.

BACKGROUND:Percutaneous vertebroplasty is the most widely used method for the treatment of osteoporotic vertebral compression fractures,and most studies have concluded that percutaneous vertebroplasty increases the probability of adjacent vertebral secondary compression fractures in patients with osteoporotic vertebral compression fractures.However,controversy remains regarding the risk factors associated with adjacent vertebral re-fracture caused after percutaneous vertebroplasty. OBJECTIVE:To summarize the influencing factors of adjacent vertebral compression fractures after percutaneous vertebroplasty in patients with osteoporotic vertebral compression fractures,in order to provide a certain reference for reducing the risk of its occurrence as well as formulating the corresponding treatment plan. METHODS:Using"osteoporosis,fracture,percutaneous vertebroplasty,adjacent vertebral compression fractures,risk factors"as the Chinese search terms,"osteoporosis,osteoporotic vertebral compression fractures,percutaneous vertebroplasty,adjacent vertebral compression fractures,risk factors"as English search terms,computerized searches were conducted on CNKI,Wanfang Medical Network,VIP,PubMed,Springer,ScienceDirect,and Elsevier databases.The search timeframe focuses on January 2018 through September 2023,with the inclusion of a few classic forward literature.The literature was screened by reading the titles and abstracts,and 83 papers were finally included in the review. RESULTS AND CONCLUSION:(1)Osteoporotic vertebral compression fractures are one of the most common complications of osteoporosis,placing elderly patients at a significant risk of disability and death.Percutaneous vertebroplasty is a practical and effective treatment for osteoporotic vertebral compression fractures.(2)With the popularity of percutaneous vertebroplasty,its secondary vertebral compression fractures have gradually increased,with adjacent vertebral compression fractures being the most common.(3)Previous studies have only discussed the effects of factors such as bone mineral density,multiple vertebral fractures,body mass index,age,sex,amount of bone cement,cement leakage,and anti-osteoporosis treatment on secondary compression fractures of adjacent vertebrae after percutaneous vertebroplasty,and summarized the number of vertebral fractures,timing of the operation,surgical approach,cement material,diffuse distribution of bone cement,recovery height of the injured vertebrae,and wearing of a support after surgery,which is not yet comprehensive.The analysis of the specific mechanisms of risk factor-induced adjacent vertebral fractures is relatively rare.(4)The results of the article showed that low bone mineral density,advanced age,perimenopausal women,multiple vertebral fractures,excessive recovery of the height of the injured vertebrae,cement leakage,comorbid underlying diseases,and poor lifestyle habits were the risk factors for secondary adjacent vertebral compression fractures after percutaneous vertebroplasty,and that maintaining a normal body mass index,early surgery,bilateral percutaneous vertebroplasty,use of a new type of cement material,an appropriate volume of bone cement injection and uniform cement dispersion,regular anti-osteoporosis treatment,and postoperative brace wearing are protective factors for secondary adjacent vertebral compression fractures after percutaneous vertebroplasty.

Posterior lumbar interbody fusion (PLIF) is currently well accepted and considered as safe and effective spinal surgical technique for the treatment of degenerative lumbar spondylolisthesis, and is widely used in clinical practice. But there are still some cases with poor overall postoperative efficacy. In order to discuss the relevant factors and mechanisms affecting the clinical outcomes of PLIF surgery, many scholars have conducted a large number of clinical studies over the years. However, due to the different methods and the factors among included studies, the conclusions reached were also different or even completely opposed. This article reviews the research results of various influencing factors of the postoperative efficacy of PLIF in recent years, and analyzes age, gender, body mass index, bone mineral density, duration of preoperative symptoms, whether the sliding vertebral body is reduced, spine-pelvic sagittal parameters (including lumbar lordosis, sacral slope, pelvic tilt, pelvic incidence, pelvic incidence-lumbar lordosis and Roussouly classification) and other factors (underlying diseases and poor lifestyle habits) on the clinical effects of PLIF, in order to provide a reference for further improving the postoperative quality of life and functional recovery of patients with degenerative lumbar spondylolisthesis.

Objective:To compare the efficacy of reduction and in situ intervertebral fusion fixation in the treatment of degenerative lumbar spondylolisthesis.Methods:A total of 182 patients (92 males and 90 females) with L 4 degenerative lumbar spondylolisthesis of Meyerding's classification of grade I and grade II, aged (62.6±6.8) years (range, 57-73 years), who underwent posterior L 4, 5 internal fixation and interbody fusion in the Department of Spinal Surgery, the Second Hospital of Shanxi Medical University, were retrospectively analyzed from January 2019 to December 2022. There were 105 cases of I-degree spondylolisthesis and 77 cases of II-degree spondylolisthesis. According to the operation method, the patients were divided into reduction intervertebral fusion fixation (reduction group) and in situ intervertebral fusion fixation group (in situ group). Imaging parameters such as lumber lordosis (LL), pelvic incidence (PI)-LL, L 3, 4 intervertebral space heights, fusion segment angle, and sagittal vertical axis (SVA) were measured on the pre- and post-surgical lumbar spine lateral radiographs. The visual analogue scale (VAS) and Oswestry Disability Index (ODI) of low back pain were recorded before and after surgery. The differences in clinical and imaging parameters were compared between reduction and in situ fusion group. Results:All 182 patients successfully completed the surgery and were followed up for 12.0±2.4 months (range, 9-15 months). The LL of the reduction group before surgery, immediately after surgery, and at the last follow-up were 46.9°±7.1°, 57.2°±5.9°, 55.6°±5.5°, respectively, with statistically significant differences ( F=87.61, P<0.001), with immediate and final follow-up being smaller than those in the in situ fixation group. The LL of the in situ fixation group before surgery, immediately after surgery, and at the last follow-up were 47.8°±7.2°, 50.5°±7.0°, and 48.7°± 6.4°, respectively, with no statistically significant difference ( F=2.83, P=0.062). The immediate and final follow-up of LL in the reduction group was lower than those in the in situ fixation group ( P<0.05). The fusion segment angles of the reduction group before surgery, immediately after surgery, and at the last follow-up were 14.2°±5.1°, 23.2°±4.7°, 23.2°±4.7°, respectively, with statistically significant differences ( F=152.87, P<0.001), with immediate and final follow-up after surgery being greater than before surgery. The fusion segment angles of the in situ fixation group before surgery, immediately after surgery, and at the last follow-up were 15.4°±5.9°, 18.2°±5.5°, and 17.4°±5.1°, respectively, with statistically significant differences ( F=4.69, P=0.009), with immediate and final follow-up being greater than before surgery. The fusion segment angulation in the reduction group was greater than that in the in situ fixation group at both the immediate and final follow-up ( P<0.05). The SVA of the reduction group before surgery, immediately after surgery, and at the last follow-up were 16.9±18.2 mm, 9.5±12.0 mm, and 8.7±11.3 mm, respectively, with statistically significant differences ( F=11.32, P<0.001), with immediate and final follow-up being smaller than before surgery. The SVA of immediately after surgery and at the last follow-up were both smaller than before surgery. The SVA of the in situ fixation group before surgery, immediately after surgery, and at the last follow-up were 16.4±17.2 mm, 14.3±15.5 mm, and 13.8±15.0 mm, respectively, with no statistically significant difference ( F=0.57, P=0.576). The SVA of the reduction group at immediate and final follow-up was lower than that of the in situ fixation group ( P<0.05). Conclusion:Both reduction and in situ intervertebral fusion fixation can effectively relieve the clinical symptoms of patients. Fusion fixation after reduction can improve the angulation of fusion segments to form segmental kyphosis, which is more conducive to improving SVA.
