The Importance of Clavicle Angle and Height of the Coracoid Process in Idiopathic Scoliosis

Abstract

Objective The aim of this study was to correlate the parameters of shoulder alignment with the Cobb angle value of the proximal thoracic curve in the pre and postoperative periods. Methods A retrospective data collection study was carried out, in which 30 medical records and radiographic examinations of patients submitted to surgical treatment for correction of deformity in AIS were performed in a single center from 2010 to 2017. Results The risk of CHD> 3 mm at 1 year postoperatively was similar between patients who had high thoracic curve (HTC) less than or equal to 25 degrees and those who had HTC greater than 25 degrees and not structured (relative risk = 1.75, P-value = 0.552). The risk of presenting CA> 2 degrees in the postoperative period of 1 year was similar between patients having HTC less than or equal to 25 degrees and those who had HTC greater than 25 degrees and not structured (relative risk = 1.31, P-value = 0.567). Conclusions We observed that when the proximal thoracic curve is not structured, even with a high Cobb angle, there is no need for instrumentation, presenting a satisfactory shoulder alignment in the postoperative period . Level of Evidence III; Retrospective and Comparative.
