How to Optimize Reverse Shoulder Arthroplasty for Irreparable Cuff Tears.

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Functionally irreparable rotator cuff tears (FIRCT) often require surgical intervention.
• Reverse shoulder arthroplasty (RSA) is a common treatment option for FIRCT.

Purpose of the Study:

• To review techniques for optimizing outcomes of RSA in patients with FIRCT.
• To provide insights into managing specific challenges associated with RSA for FIRCT.

Main Methods:

• Review of current literature and surgical best practices for RSA in FIRCT.
• Discussion of implant selection, surgical technique modifications, and adjunctive procedures.

Main Results:

• RSA demonstrates satisfactory outcomes for many FIRCT patients.
• Patient satisfaction may be lower with preserved preoperative motion or isolated external rotation loss.
• Global lateralization implants are increasingly utilized.
• Minimizing impingement and maximizing deltoid/rotator cuff function are key.
• Subscapularis repair remains controversial.
• Tendon/muscle transfers can improve outcomes in specific cases of weakness.

Conclusions:

• Optimizing RSA for FIRCT requires careful surgical planning and execution.
• Attention to indications and technical details is crucial for successful outcomes, especially in non-arthritic shoulders.
