Osaka Medical College Brace in Scoliotic Adolescent

Study design and objectives: Short underarm brace has been developed recently in the conservative treatment of progressive idiopathic scoliosis other than the widely accepted Milwaukee brace. Osaka Medical College (OMC) brace designed by Professor Onomura was one of them. This study was conducted to evaluate its effectiveness in a prospective protocol. Materials and Methods: Form June 1994 to Augut 1996, twenty-two cases with idiopathic scoliosis treated by OMC brace were evaluated. These patients were regularly followed up with the standing X-ray of whole spine (AP and Lateral). The follow-up duration averaged 13 months. The parameters analyzed included correctability, apical rotation, T1 tilting angle, lateral curvature, and sagittal balance according to King’s classification. Results: The averaged correctability immediately after bracing of primary and second curve were 34% and 22%, respectively. The final correctability were 19% and 3%, respectively. For tilting, it improved in 3/22 and unchanged in 19/22. The sagittal profile seemed to be more straight. Apical rotation improved in 3/22, however, 19/22 were unchanged. The most common complaints on this brace were skin irritation (9/22) over the margin of pelvis. This could be improved by remolding the brace. Little was complained of the difficulties in sitting and squatting which were common with Boston or Milwaukee’s brace. Conclusion: Form this study, we felt that the correctability of OMC brace is favorably comparable to that of Milwaukee’s one of other studies. For King’s type I and II, the percent correctability was better in the latter. Most of the correction occurred in the primary curves in coronal plane. However, it had limitation in correcting the apical rotation and T1 tilting. More apical rotation, it seemed unchanged. The preliminary results is encouraging.
