Comprehensive Evaluation and Arthroscopic Management of Circumferential Labral Tears Following Traumatic First Time Shoulder Dislocation: A Case Report and Review

Abstract

Introduction: Pan-labral tears, commonly associated with recurrent shoulder dislocations, are a well-documented pathology. However, circumferential pan-labral tears following a first-time shoulder dislocation represent a rare and scarcely reported entity in the literature. Accurate diagnosis requires a comprehensive clinical history, physical examination, and further evaluation, often involving MRI. Even with advanced imaging, the acute nature of the injury can lead to the oversight of pan-labral tears, necessitating arthroscopic assessment for definitive diagnosis. Repairing such extensive glenoid labral tears presents a challenging task, requiring skilled surgeons to utilize accessory portals and percutaneous techniques for optimal visualization and anchor placement trajectory. To the best of our knowledge, this case report represents the first documentation of a pan-labral tear associated with a 1st-time shoulder dislocation. Case Report: A 27-year-old Asian male presented with pain and limited range of motion in the left shoulder following a single episode of anterior shoulder dislocation during cricket. Initial X-rays were unremarkable, but subsequent MRI revealed an anteroinferior labral tear with intact rotator cuffs. Arthroscopic evaluation disclosed a pan-labral tear, prompting meticulous repair under general and locoregional anesthesia. The patient achieved full recovery postoperatively. Conclusion: While pan-labral tears are typically linked to recurrent dislocations, this case underscores their occurrence in a 1st-time traumatic shoulder dislocation without overt clinical signs or fractures. Arthroscopic repair demands careful intraoperative planning to achieve optimal tensioning and alignment of labral and capsular tissues. This report contributes to the limited literature on pan-labral tears associated with initial shoulder dislocations, emphasizing the importance of arthroscopic evaluation for accurate diagnosis and successful repair.
