Anatomical repair of anteroinferior shoulder instability

ABSTRACT

This work aimed to evaluate the results of identifying the causes and pathological disorders of anteroinferior shoulder instability and accordingly treating the condition. Eighteen patients suffering from persistent disabling shoulder instability were selected after failure of conservative treatment. Patients with anteroinferior instability were examined clinically, radiologically and arthroscopically if available to reach the etiological and pathological underlying factors. Redundancy of the capsule and capacious inferior pouch were detected in all cases of anteroinferior instability. Tear of the labrum and Hill Sachs lesion were found in some patients. Capsular shift procedure and repair of Bankart lesion if present were done. The technique which allows performing the two procedures was described. The results were satisfactory in all patients except two cases. It was concluded that anatomical repair including capsuloplasty and obliteration of the capacious inferior capsular pouch gave good results in treating recurrent anteroinferior shoulder instability
