Modified subpectoral biceps tenodesis

The proximal part of the long head of the biceps muscle has become a recognized cause of significant shoulder pain. Tenodesis of the long head of the biceps has been advocated as a treatment for pain resulting from biceps tendonopathy, biceps instability, and biceps tendon tears. All of these pathologies may be encountered during rotator cuff, SLAP or Bankart surgery, or in isolation. Several techniques have been described for this tenodesis, including various arthroscopic and subpectoral methods.

We present a modified bone bridge technique of Mazzocca et al., for subpectoral biceps tenodesis. In this technique we tenodese the tendon through two bone tunnels back over the muscle itself without implants.

Application of this technique on 30 patients (ages 25-48 years) with short-term follow-up of 12-18 months showed statistically significant improvement (P value < 0.05) of the mean Constant and Oxford shoulder scores (pre-operative mean scores were 39.03 and 21.3, respectively, while postoperative mean scores were 76.43 and 44.8, respectively).

This technique has potential advantages as it allows the possibility of adjusting the tension of the biceps tendon before final suturing, in addition to quicker soft tissue healing.
