Analysis of Bristow-Later jet procedure in the treatment of recurrent traumatic anterior dislocation of shoulder

Abstract

The shoulder by virtue of its anatomy and biomechanics is one of the most unstable and frequently dislocated joints in the body, accounting for nearly 50% of all dislocations. Since the beginning of century more than 150 surgical procedures were described in treating recurrent dislocation of the shoulder with varying results and success. Most of the operative techniques described for the treatment of recurrent anterior dislocation or subluxation of the shoulder have 2 distinct disadvantages; need to immobilize the shoulder for several weeks and Loss of external rotation. These can be overcome by Bristow-Laterjet procedure. We analysed Bristow-Laterjet procedure in the treatment of recurrent traumatic anterior dislocation of shoulder at the Department of Orthopaedics, Chengalpattu Medical College Hospital, Chengalpattu, Tamilnadu, India. We came across 20 patients (1 patient had bilateral dislocation) during February 2015 to February 2017. All the patients were followed up periodically both clinically and radiologically till their shoulder regained full range of movements and radiological bony union of the coracoid graft. All the patients were thoroughly examined and evaluated subjectively and objectively and outcome was assessed by Rowe's scoring system. We found all the patients were satisfied with surgery and were able to return to their pre dislocation level activity and none had further episodes of shoulder instability. Radiologically there was good bony union of the coracoid graft and there was no screw loosening.
