    Title Acromial Compromise with Use of a Transacromial Portal: a Biomechanical Study.
    Date February 1996
    Journal Journal of Shoulder and Elbow Surgery / American Shoulder and Elbow Surgeons ... [et Al.]

    In an experimental evaluation with 14 paired cadaveric scapulae we found that the transacromial arthroscopy portal, used occasionally in the repair of superior labral lesions, will reduce the structural integrity of the acromion to approximately 60% (range 25% to 85%) of its original strength, thereby placing it at increased risk of fracture. These studies provide baseline biomechanical information and suggest that limited shoulder activity is indicated after use of this portal.

    Title Evaluation of Impingement Syndromes in the Overhead-throwing Athlete.
    Journal Journal of Athletic Training

    OBJECTIVE: We outline impingement entities, describe the history and physical examination, and provide an overview of treatment beyond that routinely used in glenohumeral and scapulothoracic dysfunction. BACKGROUND: In the athlete, pain and dysfunction due to excessive overhead use or abnormal positioning of the shoulder is common and can result from multiple etiologies, including impingement syndromes. Primary, secondary, internal, and coracoid impingement have all been described. DESCRIPTION: These entities will be discussed, including pathology, evaluation, and treatment. CLINICAL ADVANTAGES: Incorporating a systematic evaluation and treatment of impingement syndromes optimizes care for the patient with shoulder pain.
