| ABSTRACT |
|
The thoracolumbar spine is frequently involved in spinal injuries, with more than 50% of all vertebral body fractures. This fractures may cause injuries to the spinal cord or nerve roots. Therefore the appropriate management, including surgery of that lesion, is very important and can determine the long-term outcome of the treatment. The authors analyzed the surgical results of twenty-nine thoracolumbar spine fractures treated with anterior or posterior internal skeletal fixation from August. 1990 to December, 1995. The indications for surgery were based on the neurological state and radiological findings of the patients. The selection of surgical approach(anterior or posterior) depended on the presence of neural or canal compression, the initial radiological findings, and the extent of reducibility of the fractures. Of twenty-nine patients, 21 cases were operated via the anterolateral route with Kaneda or Z-plate. The others were operated through the posterior approach with Diapason transpedicular system. They were grouped into one of three categories according to the radiological findings by Gertzbein's classification. A type fractures were most common(12 cases), B was 11, and C was 6 cases. Surgical results were evaluated by neurological recovery and achievement of stable reduction. Postoperative neurologic recovery rate was 76.2% in the case of anterolateral approach and 50.0% in the case of posterior approach. The reduction of kyposis and compression in types of A and B was prominent(P<0.01) but in type C it was not.
The authors conclude that the operation with anterior and posterior internal skeletal fixation for the treatment of unstable thoracolumbar fractures can improve neurological recovery and normalize anatomical deformities. |
