Abstract
Introduction: In rigid AIS, the main resistance for thoracic derotation are the anteriorly rotated ribs on the concavity. This study presents clinical and radiographic long term results of the CTP, which is a routine surgical procedure at the authors’ institution.
Material and Methods: Between 1996 and 1997 we have operated on 466 cases of scoliosis. 36 patients with thoracic AIS were evaluated. Technique: The ribs on the concave side are osteotomised close to the costo-transverse joint and elevated over the bended rod.
Results: Mean follow up was 6.4 y. Mean preoperative side bending flexibility was 21%. Mean correction rate was 68%, mean rib hump correction was 3cm. Mean loss of correction 4°. There was no neurological complication, and pulmonary morbidity was not increased.
Conclusion: In rigid thoracic scoliosis, a release of the concave ribs by means of the CTP can both significantly increase the extent of correction and contributes to an excellent cosmetic result.
