Biceps Tendon Properties Worsen Initially but Improve Sixteen Weeks Following Rotator Cuff Tears in a Rat Model
ثبت نشده
چکیده
INTRODUCTION: Pathologic changes in the long head of the biceps tendon are common clinically in conjunction with rotator cuff tears [1,2]. However, there is some debate regarding the role of the biceps at the shoulder following a cuff tear [3,4] and therefore, controversy exists regarding its treatment. A previous study in a rat model determined that the biceps tendon was detrimentally affected by the presence of rotator cuff tears [5], but biceps tendons were not evaluated beyond 8 weeks following rotator cuff detachments. A chronic animal model of this condition would be extremely valuable to evaluate treatment strategies for biceps pathology. Therefore, the objective of this study was to determine the histological, organizational, and mechanical changes in the long head of the biceps tendon in the presence of a multiple rotator cuff tendon tear over time. We hypothesized that all properties would worsen from 1 to 4, 4 to 8 and 8 to 16 weeks.

Damage to the biceps tendon is common clinically and is frequently seen in the presence of rotator cuff tears. However, there is some debate over the role of the biceps tendon at the shoulder following a rotator cuff tear with some believing the biceps to play a significant role as a humeral head depressor while others believe the biceps plays no role at all. Therefore, controversy exists regar...

Introduction Rotator cuff tendon tears are a common cause of pain and disability. An intact rotator cuff stabilizes the glenohumeral joint, allowing for concentric rotation of the humeral head on the glenoid. However, large tears involving the supraspinatus and infraspinatus tendons may disrupt the normal balance of forces, resulting in abnormal joint loading which can cause secondary damage to...

BACKGROUND Pathology in the long head of the biceps tendon often occurs in patients with rotator cuff tears. Arthroscopic tenotomy is the most common treatment. However, the role of the long head of the biceps at the shoulder and the consequences of surgical detachment on the remaining shoulder structures remain unknown. QUESTIONS/PURPOSES We hypothesized that detachment of the long head of t...
متن کاملBiceps Mechanical Properties Are Not Altered in the Presence of Asymptomatic Rotator Cuff Tendon Tears
Introduction The long head of the biceps (LHB) tendon has different loading patterns in its intraand extra-articular regions. The intra-articular region is exposed to complex loads including tension, compression, shear, and frictional forces, while the extra-articular portion is subjected primarily to tensional loads. Previous studies have also shown that the intra-articular region has a more d...
