Summary: Arthroscopic assisted Latissimus Dorsi tendon transfer versus arthroscopic repair for the management of massive rotator cuff tears
The management of massive rotator cuff tears (MRCT) represents a challenge. Arthroscopic assisted Latissimus dorsi muscle-tendon transfer (aLDT) and arthroscopic repair (AR) are two valuable options for the treatment of MRCT.
A total of 58 patients presenting MRCT have been enrolled in the study. 27 patients (16 males and 11 females; mean age 60 years, range 46-67 years) underwent aLDT (group A), while 31 patients (18 males and 13 females; mean age 62 years, range 40-72 years) underwent AR (group B). 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 27 months (range 24-36) in group A and 36 months (range 12-48) in group B.
The outcome variables considered (Constant and Murley score, shoulder range of motion in external rotation, and muscle strength in forward elevation) have been compared using a two-tailed Mann-Whitney U test. The significance was set at P< 0.05. The independent variables analyzed were: age; sex; arm dominance. Comparison between the two groups for each independent variable was carried out with a two-tailed Mann-Whitney U test for continuous variables and the x2 test for categorical variables.
There were no differences between the two groups for each independent variable considered (age; sex; arm dominance). The mean Constant Murley score was 74 points (40-84) in group A and 72 points (range 45-90) in group B (P= 0.65). The external rotation averaged 38° (range, 22°-40°) in group A and 35° (15-45°) in group B (P< 0.05). The mean muscle strength in forward elevation was 1.8 Kg (range 0.5-4 Kg) in group A and 4 kg (range 2-7 Kg) in group B (P< 0.05).
No differences in terms of Constant Murley score have been found between the two groups. Patients who underwent aLDT showed a significantly better external rotation. On the other hand, patients who underwent AR showed a significantly better strength in forward elevation.
