Functional outcome of open latarjet procedure for recurrent anterior shoulder instability: A prospective study

Abstract

Introduction: Shoulder joint owing to its anatomy and biomechanics is the most unstable and frequently dislocated joint in our body. Anterior shoulder instability is often caused by glenoid and/or humeral bony defects in addition to soft tissue injuries. Most commonly seen in young and athletic population with high demand activities. Arthroscopic Bankart repair and open Latarjet procedure are the mainstay of treatment for recurrent anterior shoulder instability. Here we analyse the functional outcome of the shoulder joint repair following Open Latarjet procedure for recurrent anterior shoulder instability. Methods: Prospective study conducted for 2 years among 34 patients who met our criteria for open Latarjet procedure. In which coracoid process along with the conjoint tendon is transferred and fixed with non-absorbable to the margin of glenoid. This procedure provides stability by bony effect, Bankart effect and dynamic sling effect. Phased Rehabilitation was customised based on tissue quality, stability of repair. Outcome was assessed with ISIS score (Injury Severity Index Score), Rowe score, quick DASH (The Disabilities of Arm, Shoulder and Hand) score, ASES score (The American Shoulder and Elbow Surgeons Shoulder Score) and Visual analogue scale. Results: Follow up done at 2 weeks,1 month,3 month and 6 month showed progressive improvement in Range of motions, Apprehension relief, pain relief, return to normal activities and no any recurrence of instability and improved assessment scores.Conclusion: For recurrent anterior shoulder instability Open Latarjet procedure showed satisfactory result in terms of stability and range of motion mainly with significant bony defect of glenoid.
