The Correlation between Variation of Labral Attachment and Lesions of the Long Head of the Biceps Tendon in Patients with Rotator Cuff Tears

Abstract

Objective There was no universally accepted classification system that describes LHBT lesions as a type of its' pathology in patients with shoulder pain. This study aimed to determine the correlation of anatomic variants of glenoid labrum attachment of long head of biceps tendon (LHBT) and to assess their association, if any, with its lesions in rotator cuff tear (RCT) patients. Methods All RCT patients from January 2016 to December 2019 were assessed arthroscopically to classify the LHBT labrum attachment according to its' anatomical location. A simplified classification was created to describe the LHBT as normal, tendinitis, subluxation or dislocation, partial tear and superior labral tear from anterior to posterior (SLAP) lesion beyond type II The RCT were classified as three types as partial, small to medium and large to massive. The correlation of variants of LHBT labral attachment with type of LHBT lesions in different RCT groups was evaluated. Results In total, 669 patients were included for evaluation. The attachment of the LHBT was entirely posterior in 23 shoulders (3.4%), posterior‐dominant in 81 shoulders (12.1%), and equal in 565 shoulders (84.4%). In equal distribution LHBT attachment group, age > 60 (odds ratio: 2.928, P 60 (odds ratio: 2.854, P 60 and RCT size were significant risk factors of LHBT lesions.
