Transsupraspinatus arthrotomy through an enlarged transacromial approach for total shoulder replacement.

The authors describe a step-by-step technique for anatomic total shoulder arthroplasty using transsupraspinatus arthrotomy via the enlarged transacromial approach. This technique seems ideal to ensure adequate postoperative tensional balance of the infraspinatus and the subscapularis, which is critical for the rotator cuffs to function properly and to achieve optimal arthroplasty stability. Reviewing these different steps helps understanding each rotator cuff individual component's contribution to achieve optimal arthroplasty stability.
