Biomechanics of Biodegradable Subacromial Balloon Spacer for Irreparable Superior Rotator Cuff Tears: Study of a Cadaveric Model.
A subacromial balloon spacer is an option to treat irreparable rotator cuff tears. We hypothesized that the balloon would restore glenohumeral contact pressure, the acromion-humeral interval, and deltoid load to intact values after a simulated irreparable supraspinatus tear in a cadaveric model. ⋯ This study supports further investigation of the balloon spacer in comparative clinical studies of surgical options for irreparable rotator cuff tears, with clinically relevant evaluation measures and observation periods.
