Abstract:
In the treatment of fractures of the thoracolumbar junctiion area, surgical intervention was performed when posterior part of veretbral body, posterior structure supporting ligaments were involved and body compression more than 40%. Number of cases satisfying above criteria were seven between Aug. 1990 and Jun. 1991. Age distribution ranged from 15 to 57 years. Sex ratio was 4:3(F:M). Four patients presented with nerve root sign, one patient with cauda equina signs, and two patients were normal neurologically. In all cases, spinal canal decompression, internal instrument fixation, and bone fusion with iliac bone were performed via anterolateral approach. After surgical treatment, neurological deficits disappeared and kyphotic angle returned to normal range of thoracolumbar junction area in all cases. Percentage of body compression was improved from preop. 55% to postop. 21% in average. According to above results, we concluded that anterior instrumental fixation combined with bone fusion using iliac bone was supperior to posterior approach in providing biomechanical stability and decompression of protruding ventral bone fragments.
