Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

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.

Objective: To define radiographic features that response to serial casting and bracing for progressive early-onset scoliosis (EOS). Methods: A retrospective study of a total of 20 patients (10 females and 10 males) with complete radiographic data diagnosed as progressive early onset scoliosis treated with serial cast or brace for at least 12 months in the 306th Hospital of PLA from June 2011 to April 2018. Ages at initial diagnosis were all less than 5 years old. They were divided into two groups according to the main curve degree, those with cobbs angles more than 50 degree treated with serial cast, or else with brace. All the cases have radiographs of pretreatment, posttreatment, and last follow-up, and anteroposterior (lateral) film of the full length spine in standing position were taken to evaluate magnitudes and balance of coronal and sagittal malformations. We compared the general data of the two groups by independent sample t test and that of pretreatment, posttreatment and the last follow-up by paired-sample t test. Results: According to the effective standard of not less than 10 degrees improvement, 9 of them were effective, 4 cast and 5 brace, the effective rates were 44.44% and 45.45%, 3 cases from brace group progressed. The magnitudes of the main curve improved significantly after the first treatment of cast and brace (55.4±24.36 vs 42.35±23.62) degree (t=5.850, P=0.000), and at the last follow up, the curve decreased slightly compared of that before interventions (55.4±24.36 vs 51.8±26.33). The compensatory curves, segmental kyphosis, thoracic kyphosis, lumbar lordosis, balance of both coronal and sagittal also had no significant differences between the primal and the latest follow up. The widths 159.63±19.27 mm, 160.81±14.54 mm, 176.08±28.10 mm (t=3.942, P=0.001; t=-3.096, P=0.006) and heights 153.78±29.24 mm, 161.14±29.53 mm, 175.01±36.91 mm of the thoracic were significantly different between pre-posttreatment and the last follow up (t=-5.950, P=0.000; t=-3.997, P=0.001). Serial cast and brace application can preserve the growth of the thorax. Conclusion Serial cast and brace are viable growth friendly methods to deal with progressed EOS, Although a cure improvement cannot be always expected, they can stabilize relatively large curves in young children and may help delay eventual surgical intervention.

Objective To investigate the safety and efficacy of three column osteotomy (3-CO) procedures through previous spinal fusion site for the revision surgical treatment in severe spinal deformity patients.Methods From Oct.2010 to May 2014 in our hospital,a total of 12 severe spinal deformity patients underwent 3-CO for the revision surgical treatment.There were 7 males and 5 females with the average age of (21.8±3.8) years,ranging from 18 to 30 years.The mean time from the initial operation to the revision surgery was (10.2±4.8) years (ranging from 3 to 17 years).The reasons for revision were:curve progression in 7 patients,neurologic deficit in 2 cases,implant failure in 1 patient and pseudarthrosis in 2 patients.The coronal parameters including major Cobb angle and distance between C7 plumb line and center sacral vertical line (C7PL-CSVL),and the sagittal parameters including global kyphosis curve and sagittal vertical axis (SVA) were measured pre-operatively,post-operatively and at last followup,respectively.The operation time,intraoperative blood loss and complications were recorded.The paired t test was used to evaluate the difference among pre-revision,post-revision and last follow-up.Results The average operation time was (451.7±83.1) min (range,320-600 min) and the average blood loss was (4 016.7± 1 080.0) ml (range,2 700-6 000 ml).The average follow-up time after revision operation was (35.4±9.8) months (range,24-49 months).The coronal Cobb angles of pre-revision and post-revision were 83.8°±23.3°and 34.6°± 13.7°.The average correction rate was 60.1％ ±8.8％.At last follow-up,the average coronal Cobb angle was 34.9°±13.8°,there was no significant loss of correction.The pre-revision and post-revision values of global kyphosis were 99.1°±13.3°and 38.7°±7.8° with a mean correction rate of 60.8％ ±6.7％.At the last follow-up,the average global kyphosis was 39.3°±7.5°and no loss of correction was found.For the C7PL-CSVL and SVA,pre-revision (30.3± 17.1) mm and (40.1±31.1) mm were corrected to (14.3 ±7.6) mm and (19.1± 12.3) mm immediately after revision operation,respectively.At final follow-up,the average C7PL-CSVL and SVA were(14.1 ± 7.6) mm and (19.6± 12.1) mm,the correction was well maintained.Obviously,two patient's neurological status improved from Frankel C before revision surgery to Frankel E.Complications were encountered in five patients (41.7％),including SEP signal changed in 1 patient (8.3％),transient neurologic deficit after revision surgery in 1 patient (8.3％),cerebrospinal fluid leak in 1 patient (8.3％),and pleural effusion in 2 patients (16.7％).During the follow-up time,there was no patient experienced pseudarthrosis,implant failure,infection or significant loss of correction.Conclusion Based on results of this study,it was concluded that 3-CO procedures through previous spinal fusion sites could obtain satisfactory and safety results in severe spinal deformity revision surgery.However,it is a technique-demanding procedure with more blood loss,longer operative time and higher risk of perioperative complications.

OBJECTIVETo determine the feasibility of single dose intravesical epirubicin in the prevention of recurrent superficial bladder carcinoma.

METHODSWe compared the effect of intravesical epirubicin or mitomycin C on tumor recurrence and disease free interval and their side effects after treatment of superficial bladder tumor. 47 postoperative patients with stages Ta to T1 primary superficial bladder carcinoma of grades 1 or 2 were randomized into groups A: single 80 mg epirubicin; B: 40 mg consecutive epirubicin; C: 40 mg consecutive mitomycin C. Patients were followed up for clinical, analytical, and cystoscopic evaluations every 3 months.

RESULTSThe disease free intervals of the three groups were found no significant differences (F = 3.25, P > 0.05). The recurrence rate was 6.25% (1/16), 13.3% (2/15), 12.5% (2/16) (chi(2) = 0.496, P > 0.05) in groups A, B, and C at 1 year, and 33.3% (5/15), 26.7% (4/15), 25% (4/16) (chi(2) = 0.290, P > 0.05) at 3 years after operation, respectively. Side effects of group A (13.3%) were lower than those of group B (46.7%) or C (43.8%) (chi(2) = 14.56, P < 0.01).

CONCLUSIONSSingle dose of epirubicin given intravesically immediately after tumor resection is effective in preventing tumor recurrence.
