Abstract

Introduction: The objective of the present study was to evaluate the morphological changes in the intra- and extra-articular area of the long head of the biceps in patients who had undergone subpectoral tenodesis.
Methods: We included 9 patients with a diagnosis of biceps tendinitis, who underwent subpectoral tenodesis of the long head of the biceps. The removed portion of the biceps tendon was placed in 10% formalin and divided into 2 segments. The proximal area extended from the supraglenoid insertion to the proximal edge of the pectoralis major and the distal area corresponded to the insertion of the pectoralis major. The segments were histologically evaluated using the Bonar score.
Results: Macroscopically, all the tendons were found to be thickened in the proximal region. In the histological evaluation, among the most relevant variables evaluated by the Bonar score, the cell morphology score in the proximal area was significantly higher than in the distal area (p <0.0001).
Conclusion: Our findings showed higher levels of pathology within the proximal biceps, supporting the elimination of this segment for chronic biceps tendinopathy, which can be accomplished through subpectoral tenodesis.
