Open Subpectoral Tenodesis for Isolated Traumatic Long Head of Biceps Tendon Rupture Provides Excellent Functional Outcomes in Active Male Patients

Abstract

Background: For many years the long head of biceps tendon (LHBT) rupture has been described and is commonly identified by weakness, cramping, and the so-called "Popeye" sign. Traditionally, this was treated non-operatively, likely reflecting patient factors and the technical difficulty in reattaching a degenerative and shortened tendon. In contrast, traumatic distal biceps rupture is now commonly repaired despite historically being managed non-operatively. The advent of a convenient and reproducible surgical technique led to an increase in the rate of fixation, thereby improving the cramping and weakness associated with non-operative treatment. Given recent surgical advances within this field, many techniques are now present for LHBT pathology. We describe results from a cohort of patients suffering traumatic LHBT rupture who sought a surgical solution to improve their symptoms.

Methods: Over four years, 18 male patients underwent surgical intervention for isolated traumatic LHBT rupture. The technique used involved an open subpectoral tenodesis with fixation of the LHBT into the bicipital groove. Postoperative immobilization using a sling was recommended for six weeks prior to a progressive rehabilitation program. Patients were assessed with pre- and postoperative visual analog scores (VAS) for pain and American Shoulder and Elbow Society (ASES) scores.

Results: The mean patient age at the time of surgery was 49 years (range: 26-65 years). The mean time to surgery was nine weeks (range: 2-24 weeks). All patients showed an improvement following surgery with a mean pre-op ASES score of 33 (range: 10-60) compared to a post-op score of 92.6 (range: 85-100). All patients were able to return to work and sport, with all but one returning to the same functional demand level of work. The mean pre-op pain VAS was 6.3 (out of 10) compared to 0.2 post-op. All patients had a requirement for analgesia pre-operatively and none had postoperatively. No surgical complications were observed. No correlation was observed between the time to surgery and the outcome.

Discussion: LHBT rupture is often treated non-operatively as few studies within the literature describe the surgical technique and outcomes from surgical intervention. When treated non-operatively, patients complain of pain, cramping, and cosmetic deformity known as the "Popeye" sign. Following a traumatic rupture of the LHBT, we have demonstrated excellent outcomes using a standard approach and common fixation technique that has the potential to improve the functional outcome for symptomatic patients.

Conclusion: Open subpectoral biceps tenodesis is associated with excellent outcomes in symptomatic patients following isolated LHBT rupture.
