Traumatic 270° and 360° labral tears of shoulder - Injury patterns, surgical technique, and mid-term outcomes.

Abstract

Large glenolabral tears (270°-360°) are infrequently reported injuries and can be challenging to manage. This study aims to describe the injury patterns, surgical technique, and midterm outcomes of arthroscopically repaired 270°-360° labral tears. Patient data was retrieved from the electronic data records from 2011 to 2021. The patients with arthroscopically confirmed and repaired 270°/360° tears (with or without superior labral anterior posterior lesions) with a minimum follow-up of 24 months were included, and Oxford shoulder instability score and visual analog score (VAS) pain score were recorded prospectively. Twenty-four patients were included in the study with a mean follow-up of 52.6 ± 24.4 months. The mean pre-operative and final Oxford instability score was 24.8 ± 4.1 and 43.2 ± 1.5 (<i>p</i> < 0.0001). The mean pre-operative and final VAS was 4.95 ± 1.12 and 0.6 ± 0.7(<i>p</i> < 0.0001). Terminal loss of external rotation was seen in five patients with the remplissage procedure. No re-dislocation or instability was reported. All patients returned to pre-injury activity levels. Pan labral tears can be challenging to diagnose pre-operatively and may result in poor outcomes. Pain can serve as a clinical indicator of larger labral pathology in patients presenting with shoulder instability. A comprehensive understanding of the injury pattern, along with a systematic surgical approach, is essential for restoring adequate joint stability and achieving satisfactory results in the general patient population.
