Abstract

PURPOSE:

The purpose of this study was to determine clinical and structural outcomes of arthroscopic repair of massive, contracted, immobile rotator cuff tears using interval slides.

METHODS:

Eleven patients who had rotator cuff tears that were irreparable using standard mobilization techniques, but were repaired using interval slides were reviewed. Patients were evaluated at mean 25.2 months (±10.3) post-operatively utilizing a standardized clinical examination and by magnetic resonance imaging (MRI).

RESULTS:

American Shoulder and Elbow Surgeons (ASES) and Simple Shoulder Test (SST) scores improved significantly (ASES p = 0.0001; SST p = 0.0001) from pre- to post-operative. Range of motion in forward elevation and external rotation increased from pre- to post-operative, though not significantly. Strength via manual muscle testing improved on forward elevation (p = 0.001) and external rotation (p = 0.007) from pre- to post-operative. Post-operative MRI demonstrated massive re-tearing to the original size in 6 patients (55 %) and intact rotator cuffs with tissue spanning the defects in 5 (45 %) patients.

CONCLUSIONS:

In patients with massive, contracted, immobile tears, an interval slide technique may be utilized as a salvage procedure. Arthroscopic repair of massive, contracted, immobile rotator cuff tears using interval slide techniques can lead to good clinical and satisfactory structural outcomes.

LEVEL OF EVIDENCE:
