Abstract

Background:

Irreparable rotator cuff tears associated with shoulder functional impairment represent a challenge, especially in young and active patients. Latissimus dorsi muscle-tendon transfer is performed to replace the irreversibly lost contractile elements in patients with irreparable tears of the posterosuperior aspect of the rotator cuff.

Methods:

From 2008 to 2010, we enrolled twenty-seven patients (mean age, sixty years; range, forty-six to sixty-seven years) with irreparable, full-thickness rotator cuff tears involving at least two tendons who underwent arthroscopic-assisted latissimus dorsi muscle-tendon transfer. Outcome measures included the Constant and Murley score, shoulder range of motion in external rotation, and muscle strength in forward elevation. The mean duration of follow-up was twenty-seven months (range, twenty-four to thirty-six months).

Results:

There was a significant improvement (p < 0.05) in the mean Constant and Murley score, pain score, muscle strength in forward elevation, and range of motion in external rotation at the time of the last follow-up. There was no significant correlation between the mean preoperative range of motion, pain, and strength and the mean postoperative Constant and Murley score. There was no significant osteoarthritis progression and proximal migration of the humeral head after surgery in the time period studied.

Conclusions:

Arthroscopic-assisted latissimus dorsi muscle-tendon transfer at short-term follow-up is an effective alternative to open surgery for the management of painful irreparable posterosuperior rotator cuff tears refractory to conservative management.

Level of Evidence:

Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
