Arthroscopic supraspinatus advancement for retracted rotator cuff tears: a technical note.

Abstract

Irreparable rotator cuffs with retracted torn ends remain a significant challenge for most shoulder surgeons. Since repairs are preferable to reconstruction or replacement whenever possible, studies for anatomical reductions with minimal tension and secure fixation are important. In this study, the authors introduce an arthroscopic supraspinatus advancement (ASSA) procedure for retracted rotator cuff tears that could not be adequately reduced to the original footprint. Using modified long, narrow, curved Cobb elevators, procedures can be performed through lateral portals without any additional skin incision. Following meticulous stepwise three-compartment elevation procedures based on the supraspinatus insertion anatomy, the supraspinatus muscle could be safely elevated from the fossa and sufficiently advanced laterally. The authors suggest that ASSA could be a useful procedure for management of challenging retracted rotator cuff tears by maximizing lateral excursions that could convert irreparable tears to reparable tears in select patients.
