Arthroscopy of the shoulder is not routinely preformed during reconstruction of the acromioclavicular joint. During an open AC joint reconstructive procedure, failure to recognize and address glenohumeral joint (GHJ) pathology can adversely affect outcomes. There is no consensus in the literature regarding the need for a narrowing of the subcoracoid space may lead to mechanical conﬂicts that result in injury to the rotator cuff, biceps, and biceps pulley.
The coracohumeral interval (CHI) is associated with age and gender but has not been standardized to size and anatomic location. The purpose of this study: “Subcoracoid Impingement: Factors Associated with the Size and Location of the Coracohumeral Interval”, was to determine clinical and anatomic factors associated with the size and location of the CHI.
