Functional Outcomes of Arthroscopic Bankart Repair for Traumatic Anterior Shoulder Instability
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2019, Vol 4, Issue 7
Abstract
Shoulder is one of the most unstable and frequently dislocated joint in the body, accounting for more than 50% of all dislocations, with a 2% incidence in the general population. Main complication of shoulder dislocation is recurrent instability and it accounts for an average of 70-90% recurrence rate in patients between 20-40 years of age. During shoulder dislocations, humeral head is forced anteriorly out of glenoid cavity resulting in detaching fibrocartilaginous labrum from the anterior rim of glenoid cavity. This detachment of glenoid labrum is called Bankart lesion. Bankarts lesion is the most common and essential lesion in treatment of anterior shoulder instability In 1938 Bankart [1] reported excellent results of re-attachment of the capsulolabral complex in patients with anterior shoulder instability, a method first described by Perthes [2]. Management is by reattachment of labro-ligamentous structure to the glenoid. Glenoid labrum plays important role in maintaining stability of glenohumeral joint. Glenoid labrum deepens the socket and act as anchor point for ligaments and capsule. Problems reported to be associated with open Bankart repair include restriction in external rotation [3,4,5,6] and subscapularis muscle insufficiency . Therefore less invasive arthroscopic techniques have been developed and have improved from disappointingly high recurrence rates with staple capsulorrhaphy [7], transglenoid sutures [8,9] and bioabsorbable tacks [10] to promising results with suture anchors equal to open procedures . Arthroscopic stabilization is considered advantageous in terms of decreased morbidity with reduced pain and shorter hospitalization (if necessary at all), faster rehabilitation, no violation of the subscapularis tendon and no loss in range of motion [11]. Nevertheless, higher recurrence rates compared to the open procedure have been reported [12,13,14)
