SURGICAL TREATMENT OF THORACOLUMBAR VERTEBRAL FRACTURES
Journal Title: Journal of Turkish Spinal Surgery - Year 1994, Vol 5, Issue 3
Abstract
Conservative treatment of unstable thoracal and lumbar vertebral fractures results in severe local kyphosis or changes in sagittal contours in long term follow-up. This study evaluates 89 thoracolumbar vertebral fractures op-erated between December 1989 and May 1993 in the orthopaedic Clinics of Ankara Sociai Security Hospital. The mean follow-up was 30.2 months with a minimum of 12 months. The stabilization of fractures were maintained with hook-rod construction in 28 patients in whom Cotrel-Dubousset Instrumentation (CDI) was used. Thirty pa-tients had AO Fixator Intern; a transpedicular screw-rod construction. The vertebral fractures in the remainin 31 patients were stabilized with transpedicular screw-reverse hook-rod construction by using Texas Scottish Rite Hospital (TSRH) system. Preoperative sagittal index at the fracture level was 24.7°±6.5° in patients treated with CDI, 25.1°±8.2° with AO Fixator Intern and28.7°±3.4° with TSRH system. Postoperative correction rates for CDI, AOlFand TSRH system were 66.8%±26.7, 68.4~±23.2 and 79.3%±19.5 respectively. Postoperative sagittal index at the thoracolumbar junction were in physiologic limits in ali of the patients treated with TSRH system, while this rate was 70% for the AOIF and 64.3% for CDI. Because that the best spinal canal decompression and the lovvest complication rate was achieved in the TSRH system group, it is concluded that transpedicularscrevv-reverse hook combinations is the best construction type for the stabilization of unstable thoracolumbar fractures.
