Total Shoulder Arthroplasty Utilizing the Subscapularis-Sparing Approach.

Area of Science:

• Orthopedic Surgery
• Shoulder Arthroplasty
• Surgical Techniques

Background:

• The deltopectoral approach for total shoulder arthroplasty traditionally involves subscapularis tendon violation.
• Subscapularis tendon dysfunction is a known complication following this approach.

Purpose of the Study:

• To introduce and evaluate a subscapularis-sparing surgical approach for total shoulder arthroplasty.
• To reduce the incidence of postoperative subscapularis dysfunction and improve clinical outcomes.

Main Methods:

• A novel surgical technique performed entirely through the rotator interval, preserving the subscapularis tendon.
• Comparison of outcomes with traditional deltopectoral approach (implied).

Main Results:

• The subscapularis-sparing approach facilitates earlier patient rehabilitation.
• This technique may prevent subscapularis insufficiency and subsequent clinical failures.

Conclusions:

• The rotator interval approach offers a viable alternative to the deltopectoral approach for total shoulder arthroplasty.
• Preserving the subscapularis tendon can lead to improved functional recovery and reduced complication rates.
