Open anterior acromioplasty with preservation of the coracoacromial ligament: A modified surgical technique.
The importance of the preservation of the subacromial arch has been stressed recently, especially in irreparable lesions of the rotator cuff to prevent anterosuperior migration of the humeral head. The purpose of this article is to describe the surgical technique of a modified open anterior acromioplasty performed through an intra-acromial osteotomy that increases the subacromial space and preserves the insertion of the coracoacromial ligament on the undersurface of the acromion. To compare this new technique with classical acromioplasty, a prospective but nonrandomized study was performed including 20 patients undergoing open anterior acromioplasty and 22 patients undergoing a modified open anterior acromioplasty. At a mean follow-up of 18 months, no differences related to shoulder function as evaluated by the Constant score were found between these two groups. This modified acromioplasty increases the subacromial space, preserving the anatomy of the subacromial arch, and provides functional results as good as those obtained with classical open acromioplasty.
