Arthroscopic Pectoralis Minor Release.

ABSTRACT: The scapula has long been recognized as a key component in shoulder motion and a crucial part of the kinetic chain connecting the body's core and upper extremity. The pectoralis minor (PM) has garnered increasing attention as we better understand scapular kinematics and its role in shoulder pain and dysfunction. This is particularly important in patients with scapular dyskinesis and especially in overhead throwing athletes. The most of these patients achieve their recovery goals through nonoperative management, stretching, and strengthening protocols; however, some patients do not respond to nonoperative modalities. Several studies have recently shown improvement in shoulder motion and outcome scores after open surgical release of the PM from its scapular attachment. Arthroscopic release of the PM can be accomplished in the lateral decubitus position with standard shoulder arthroscopic portals.

Project description:PurposeThe term "pectoralis minor syndrome" refers to this constellation of symptoms that can occur when the pectoralis minor (Pm) is shortened and contracted. Release of the tendon of the Pm from the coracoid has been reported to provide substantial clinical improvement to patients presenting with pectoralis minor syndrome. The purpose of this study was (1) to describe the technique for endoscopic release of pectoralis minor tendon at the subdeltoid space, (2) to classify the pectoralis minor syndrome according to its severity and (3) and to report the short-term outcomes of this procedure in a consecutive series of patients diagnosed with pectoralis minor syndrome.MethodsEndoscopic release of the pectoralis minor tendon was performed in a series of 10 patients presenting with pectoralis minor syndrome. There were six females and four males with a median age at the time of surgery of 42 (range from 20 to 58) years. Four shoulders were categorized as grade I (scapular dyskinesis), and six as grade II (intermittent brachial plexopathy). Shoulders were evaluated for pain, motion, satisfaction, subjective shoulder value (SSV), quick-DASH, ASES score, and complications. The mean follow-up time was 19 (range, 6 to 49) months.ResultsArthroscopic release of the tendon of the Pm led to substantial resolution of pectoralis minor syndrome symptoms in all but one shoulder, which was considered a failure. Preoperatively, the median VAS for pain was 8.5 (range, 7-10) and the mean SSV was 20% (range, 10% - 50%). At most recent follow-up the mean VAS for pain was 1 (range, 0-6) and the mean SSV 80% (range, 50% - 90%). Before surgery, mean ASES and quick-DASH scores were 19.1 (range, 10-41.6) and 83.1 (range, 71 and 95.5) points respectively. At most recent follow-up, mean ASES and quick-DASH scores were 80.1 (range, 40-100) and 19.3 (range, 2.3-68) points respectively. No surgical complications occurred in any of the shoulder included in this study.ConclusionsEndoscopic release of the tendon of the pectoralis minor from the coracoid improves pain, function and patient reported outcomes in the majority of patients presenting with the diagnosis of isolated pectoralis minor syndrome.
