Acromion Non-Union With Associated Posterior Glenoid Labral Tear

Abstract

Acromion fractures are often associated with high velocity trauma. These fractures are relatively rare injuries with the reported incidence being 0.1% of skeletal fractures in the literature. The pathology of Acromion non-union with associated soft tissue lesions and their treatment have been sparsely reported in the literature. Our case is that of a forty year old male with complaint of pain and restriction of his left shoulder for 7 months following a road traffic accident. He was diagnosed to have an Acromion non -union with an associated posterior glenoid labral tear. We report the successful treatment of the acromion non-union and the associated posterior glenoid labral tear by a combination of Arthroscopic and open reduction procedures.

INTRODUCTION:Acromion fractures are relatively uncommon injuries accounting to around 8-10% of scapular fractures. 1 Scapula fractures by themselves are rare representing 1% of all skeletal fractures and 3-5% of shoulder fractures. 2, 3 These fractures are high energy fractures with the incidence of associated injuries ranging from 80 -95 %. 4,5
