Introduction: The aim of the study was to analyze the clinical and radiological outcomes of a series of patients with massive ruptures of the rotator cuff treated with latissimus dorsi tendon transfer. Methods: A retrospective, descriptive and observational study was performed. Patients <70 years with massive and irreparable posterosuperior lesions of the rotator cuff were treated with latissimus dorsi transfer and with a minimum follow-up of 2 years. Range of motion and strength in abduction were assessed. In addition, the visual analogue scale and modified Constant-Murley scale were recorded. Acromio-humeral distance and arthropathy stage were radiographically analyzed. Results: Seventeen patients were included (12 males, 5 females), mean age 54 years (range 34-65), with a mean followup of 46 months (range 24-71). In the primary surgery group, the average motion gain was 53o in anterior flexion, 50o in abduction and 19o in external rotation. The abduction strength recorded an average gain of 1.4 kg. Modified Constant- Murley scale of 75.6 (range 63-80) at the end of follow-up. In the revision surgery group, the gain of active motion was 48o in anterior flexion, 30o in abduction and 10o in external rotation. Abduction strength had an average gain of 1.1 kg. Postoperative visual analogue scale improved 5.1 points in the primary surgery group and 3.4 in the other group. Conclusion: Latissimus dorsi tendon transfer for the treatment of massive posterosuperior rupture of the rotator cuff showed improvements in range of motion, strength, pain relief and shoulder function.
