Arthroscopic Coracoid Excision, Conjoint Tendon, and Pectoralis Minor Release for Anterior Shoulder Pain and Impingement After Reverse Shoulder Arthroplasty.

Abstract

Anterior shoulder pain after reverse shoulder arthroplasty (RSA) is both challenging to diagnose and treat and can be attributed to the conjoint tendon, coracoid process, and pectoralis minor. Various open and arthroscopic techniques have been proposed to address singular aspects of these painful structures, although a global treatment has not been described. Herein we describe an all-arthroscopic approach to the treatment of anterior shoulder pain after RSA, incorporating subacromial and subdeltoid decompression, conjoint tendon release, pectoralis minor release, and coracoid excision. This addresses both bony and soft-tissue aspects of subcoracoid impingement and altered muscular tension after RSA.
