Enlarged transacromial superior approach with reverse shoulder arthroplasty for fractures

The authors describe a step-by-step technique for reverse total shoulder arthroplasty using arthrotomy via the enlarged transacromial superior approach. This technique seems ideal for reinsertion of the tuberosities and 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 and external rotation with a reverse shoulder arthroplasty.
