Clinical Results of Surgical Treatment with Modified Cadenat Procedure for Acromioclavicular Dislocation

Abstract

The purpose of this study was to review the results of surgical treatment with modified Cadenat procedure for a grade III dislocation of acromioclavicular (AC) joint. Materials and Metho ds. The study sample was 63 patients (54 males and 9 females) who underwent surgical treatment, their average age at surgery was 35.1 years, ranging from 16 to 56. The duration from injury to operation was from 3 to 186 days, average 29.1 day and that of follow-up was from 6 to 88 months, average 26.9 months. The evaluation consisted of 1) the clinical score described by Kawabe and factors related to them (age at operation, the duration from injury to operation, time of the removal of the K-wire, re-dislocation, reontgenographical classification of the AC joint, calcification of the coracoclavicular (CC) ligament, bone changes of the AC joint).2) Correlation between the severity of the displaced clavicle and reontgenographical abnormality. Re-dislocation was defined if the distance between the lower margin of the acromion and that of the distal end of the clavicle was 6mm or more.
