摘要："Background: The aim of this study was to investigate the effectiveness and potential complications of combining a laminalifting suspension system with the bridge crane technique in treating thoracic ossification of the ligamentum flavum (TOLF) with thoracic myelopathy. Material/Methods: A patient with severe TOLF and myelopathy was treated using a lamina-lifting suspension system combined with bridge crane technique. The brief surgical procedure involved implantation of internal fixation, separation of laminae, installation of cross-bridges, reverse lifting, and fixation of cross-bridges. The modified Japanese Orthopaedic Association (mJOA) scale, Hirabayashi recovery rate, and ASIA grade of the patient were recorded. The canal occupation ratio (COR) and spinal cord status were evaluated by imaging data. Results: The surgical intervention significantly enhances the patient's lower limb function, as evidenced by an increase in mJOA score from 5 preoperatively to 11 at terminal follow-up. The Hirabayashi recovery rate after surgery ranges between 25% and 50%. Additionally, ASIA classification improved to grade E. Imaging data showed that the ossification of the thoracic vertebrae had subsided, while the volume of the local spinal canal had recovered and the spinal cord injury had been completely relieved. No adverse effects or complications were observed. Conclusions: The lamina-lifting suspension system preserves the benefits of bridge crane technique while also augmenting the traction of a post laminae-OLF complex (LOC) suspension, rendering it more secure and manageable. Nevertheless, further sample analysis and research are required in the future."
