Objective:To evaluate clinical efficacy of Z-plate and indications for the anterior fixation system for thoracolumbar fracture.Methods:50 cases of thoracolumbar fracture underwent direct anterolateral decompression with sagittal reduction and corpectomy

antologous bone-grafting reconstruction and Z-plate fixation procedure.Results:4 cases were lost to follow-up

and 46 cases were followed up from 4 to 36 months.According to Frankel classification of neurologic deficit

36cases with neurologic deficits recovered completely;8 cases obtained a good functional outcome;2 case didn’t recoved;No patient had neurologic deterioration after surgery Neither breakage of loosening of connections wac found.conclusion:Z-plate system is an effective ideal thoracoiumbar anternal fixation system.It has the advantages of reliable easy manipuplation

safety andless comlications.
