Clinical Outcomes After Mini-Open Subpectoral Biceps Tenodesis

Background Long head of the biceps tendon pathology is a common cause of shoulder pain. Current surgical treatment options for long head of the biceps tendon disorders include tenotomy and tenodesis. Younger and high-demand patients are usually treated with tenodesis since tenotomy is associated with increased biceps pain and cramping, cosmetic deformity and patient dissatisfaction. Previous studies have shown biomechanical advantages of subpectoral open approach over arthroscopic suprapectoral approach, with less biceps over tension and increased ultimate load to failure. Despite this, there is a lack of consensus in the literature regarding the management of biceps-related pathology. Methods We retrospectively reviewed all patients who underwent subpectoral biceps tenodesis with unicortical endo-button fixation between January 2015 and December 2019. Only patients who had a minimum of 24 months follow-up were included in the study. We reviewed patient demographics. The American Shoulder and Elbow Surgeons and Visual Analogue score were assessed and complications were recorded. Results A total of thirty-two patients were enrolled in this study. 15 were young patients and sports athletes with SLAP (Superior Labrum from Anterior to Posterior) lesions or isolated biceps instability and the remaining 17 were middle-age patients with degenerative biceps disease and concomitant pathology. The mean follow-up time was 36 months. SLAP lesions group average age was 24,3 and degenerative group average age was 53,8. The ASES score and the VAS score and were statically significative better in the isolated subpectoral tenodesis due to SLAP lesions 99,8 and 0,1 respectively in comparison with the degenerative group, 85,7 and 1,5 respectively. We recorded two complications. One case of superficial infection and one case of a patient that was concomitant submitted to arthroscopic rotator cuff tear repair with persisting shoulder pain. There was no case of failure of fixation or associated Popeye deformity. Conclusions Subpectoral biceps tenodesis with unicortical endo-button fixation is a viable treatment option for patients with symptomatic biceps disease. Anterior shoulder pain and biceps symptoms were resolved with this technique. Patients with coexistent rotator cuff lesion may have less favorable outcomes.
