[Treatment of benign tumors in thoracic spinal canal by modified replanting posterior ligament complex applying piezoelectric osteotomy].

OBJECTIVE: To investigate the feasibility and effectiveness of modified replanting posterior ligament complex (PLC) applying piezoelectric osteotomy in the treatment of primary benign tumors in thoracic spinal canal. METHODS: and fixed with bilateral micro-reconstruction titanium plate. X-ray film, CT, and MRI examinations were performed to observe spinal stability, spinal canal plasty, and tumor resection after operation. The effectiveness was evaluated by JOA score. RESULTS: =0.000). Among them, 14 cases were excellent, 18 were good, 6 were fair, and the excellent and good rate was 84.2%. CONCLUSION: Modified replanting PLC applying piezoelectric osteotomy and micro-reconstruction with titanium plate for the primary benign tumors in thoracic spinal canal can reconstruct the anatomy of the spinal canal, enable patients to recover daily activities quickly. It is an effective and safe treatment.
