Open Repair of an Anterior Humeral Avulsion of the Glenohumeral Ligament.

ABSTRACT: A humeral avulsion of the glenohumeral ligament, or HAGL lesion, is an uncommon yet disabling shoulder injury, which leads to complaints of pain and overall inability to properly use the shoulder from patients. The diagnosis of a HAGL lesion is particularly challenging. To arrive at an accurate diagnosis, the use of a magnetic resonance arthrogram is suggested along with high clinical suspicion. A HAGL lesion may be anterior or posterior. This difference dictates the type of surgical treatment to be undertaken. Although a posterior HAGL lesion is repaired arthroscopically, an anterior HAGL lesion is treated through an open approach. The purpose of this Technical Note is to describe our preferred technique to surgically treat an anterior HAGL lesion through an open approach.

Project description:BackgroundHumeral avulsion of the glenohumeral ligament (HAGL) lesions are an uncommon cause of anterior glenohumeral instability and may occur in isolation or combination with other pathologies. As HAGL lesions are difficult to detect via magnetic resonance imaging (MRI) and arthroscopy, they can remain unrecognized and result in continued glenohumeral instability.PurposeTo compare patients with anterior shoulder instability from a large multicenter cohort with and without a diagnosis of a HAGL lesion and identify preoperative physical examination findings, patient-reported outcomes, imaging findings, and surgical management trends associated with HAGL lesions.Study designCross-sectional study; Level of evidence, 3.MethodsPatients with anterior glenohumeral instability who underwent surgical management between 2012 and 2020 at 11 orthopaedic centers were enrolled. Patients with HAGL lesions identified intraoperatively were compared with patients without HAGL lesions. Preoperative characteristics, physical examinations, imaging findings, intraoperative findings, and surgical procedures were collected. The Student t test, Kruskal-Wallis H test, Fisher exact test, and chi-square test were used to compare groups.ResultsA total of 21 HAGL lesions were identified in 915 (2.3%) patients; approximately one-third (28.6%) of all lesions were visualized intraoperatively but not identified on preoperative MRI. Baseline characteristics did not differ between study cohorts. Compared with non-HAGL patients, HAGL patients were less likely to have a Hill-Sachs lesion (54.7% vs 28.6%; P = .03) or an anterior labral tear (87.2% vs 66.7%; P = .01) on preoperative MRI and demonstrated increased external rotation when their affected arm was positioned at 90° of abduction (85° vs 90°; P = .03). Additionally, HAGL lesions were independently associated with an increased risk of undergoing an open stabilization surgery (odds ratio, 74.6 [95% CI, 25.2-221.1]; P < .001).ConclusionApproximately one-third of HAGL lesions were missed on preoperative MRI. HAGL patients were less likely to exhibit preoperative imaging findings associated with anterior shoulder instability, such as Hill-Sachs lesions or anterior labral pathology. These patients underwent open procedures more frequently than patients without HAGL lesions.
