Anterior release is generali indicated İn the treatment of İdiopathic scolİosİs patients with rigid curves. One staged anterior instrumentation has started with Zieike, however, high rates of morbİdİty and pseudoarthrosis rates of this system has prevented its widespread use. İn this study the results of 5 patients with one staged anterior İnstrumentation and 2 patients with anterior instrumentation followed hy posterior instrumentation were evaiuated. Mean follow-up was 18.1 months and mean age was 15.6 (11-22)years. One patient had Alıcı Spİnal İnstrumentation, one had Texas Scottish Rite Hospital System, one had Kaneda SR and remaining 4 patients had Cotrel-Dubousset-Hopf instrumentation. Preoperative mean Cobb angle of majör curves which was 85.3 (78-92) was brought to 40.7 (37-47) postoperativeiy and 52.3% ofcorrection was obtained. A solid fusion was observed in ali patients. One patient with impİant failure vvas revised. in iight of these findings it is suggested that aithough we are at the beginning of a iearning curve, encouraging results can be obtained with anterior release and instrumentation in patients with rigid curves.
