“…Besides, it is easy to operate and has less trauma and complications, so it is the first choice to deal with such injuries. 17 In the surgical treatment of thoracolumbar dislocation, posterior long-segment fixation is often used, that is, fixing at least 2 vertebral bodies in the cephalic and caudal sides of the dislocation segment, which can not only correct the anterior and posterior dislocation, but also correct the rotating lateral displacement. The postoperative stability is reliable, and the load borne by each screw is significantly reduced, which can reduce the risk of postoperative internal fixation failure.…”

The purpose of this study was to evaluate the effectiveness of a novel surgical open reduction method for thoracolumbar dislocation.Materials and Methods: This study included a total of 15 patients of thoracolumbar dislocation. All patients underwent posterior thoracolumbar open reduction and fixation using this technique. Preoperative x-ray, computed tomography (CT), and magnetic resonance imaging were used to evaluate the dislocation. The American Spinal Injury Association grade of spinal cord injury before and afer the operation were record. All patients were followed up for 2 years, and x-ray, CT were used to observe postoperative reduction and fusion.Results: Postoperative x-ray and CT images of all patients indicated good recovery of the spinal sequence, and no neurological deterioration or surgically related complications occurred. All patients were followed up for 2 years, no patients were lost to follow-up. During the follow-up period, x-ray and CT images showed no complications related to internal fixation such as fracture and loosening of screws and rods were found. Conclusion:A anchoring technique using long bent rods is a safe, simple, accurate, and easy to replicate and implement method, which can be applied in the surgical treatment for thoracolumbar dislocation.

“…Our study suggested that PV reinforcement with IBPSF could help provide better kyphosis correction, which more effectively restores fractured segment height, thus improving the biomechanical stability of unstable OVCFs [10–14, 20]. Traditional short-segment 4 pedicle screw fixation is widely used.…”

Vertebroplasty and vertebroplasty in combination with intermediate bilateral pedicle screw fixation for OF4 in osteoporotic vertebral compression fractures: a retrospective single-Centre cohort study

BackgroundAlthough various studies have described the outcomes and complications of each treatment for OF 4 in osteoporotic vertebral compression fractures (OVCFs), there is still no consensus on the optimal treatment regimen. This study aimed to investigate the clinical effect of OF 4 in patients with OVCFs treated with percutaneous vertebroplasty (PV) compared with PV in combination with intermediate bilateral pedicle screw fixation (IBPSF).MethodsA total of 110 patients with OF 4 in OVCFs from January 2011 to December 2013 were reviewed retrospectively and divided into two groups (group A: PV, group B: PV + IBPSF). According to the guidelines of the German Society for Orthopaedics and Trauma (DGOU), OF 4 consists of 3 fracture types. The clinical and radiographic assessments were observed preoperatively, postoperatively, and during follow-up.ResultsThe patients were followed for an average of 60.50 ± 15.20 months (group A) and 58.20 ± 17.60 months (group B) without significant differences. No significant differences were found in BMD, BMI and cement volume between the two groups, but differences were found for operation time, blood loss, and hospitalization time. The VAS and ODI scores improved better significantly at the final follow-up in group B but not in group A. Compared with the preoperative values, the postoperative kyphosis angle and loss of fractured segment height significantly improved, but the difference between the groups was significant after 3 months postoperatively. The loss of angular correction and fractured segment height in group A were greater than those in group B. A total of 15 cases of cement leakage were observed in group A and 8 cases in group B, and no complications or revision surgeries were observed in either group. Thirteen new fractures occurred (11 in group A and 2 in group B), which was significant.ConclusionPV with IBPSF could provide effective restoration and maintenance of fractured segment height and segment alignment as well as a lower rate of complications of OF 4 in OVCFs.

“…The biomechanical properties of monoaxial pedicle screws have been widely reported 17–20. Segmental fixation with additional monoaxial pedicle screws at the level of the fracture increases construct stiffness and shields the fractured vertebral body from anterior loads.…”

Primary bone lymphoma (PBL) comprises less than 5% of all malignant bone tumors and almost 7% of all extranodal lymphomas. Only 1.7% of all PBLs have been reported to involve the vertebrae. In our case, osteomyelitis was accidentally found during surgery, which might have resulted in the rapid collapse of vertebral body. This is the first report on primary lymphoma of the vertebrae with superimposed osteomyelitis in the English literature to the best of our knowledge. The patient reported here received anterior vertebrectomy and posterior interbody fusion with instrumentation for spinal instability. Tumor mass and the necrotic debris were removed. After the procedure, the patient received treatment with antibiotics and six cycles of chemotherapy. This case reminds us the possibility of hematologic seeding of bacteria in the tissue, especially with tumor necrosis. We suggest percutaneous needle aspiration for pathology and culture before making a decision whether or not to proceed with surgical decompression for fear of missing the occult bacterial infection.
