Subscapular and Pectoralis Major Sparing Deltopectoral Approach for Reverse Total Shoulder Arthroplasty

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Traditional reverse shoulder replacement often involves the deltopectoral or anterosuperior transdeltoid approach.
• The deltopectoral approach requires incision of the pectoralis major and detachment of the subscapularis tendon, potentially impacting shoulder deltoid function.
• Existing methods may compromise rotator cuff integrity.

Purpose of the Study:

• To describe a modified surgical technique for reverse ball shoulder replacement.
• To present an approach that avoids incision of the pectoralis major muscle.
• To detail a method that preserves the subscapularis muscle and tendon.

Main Methods:

• A novel surgical procedure for reverse ball shoulder replacement is detailed.
• The technique emphasizes avoiding the pectoralis major muscle incision.
• The subscapularis tendon is preserved at the lesser tuberosity of the humerus.

Main Results:

• The described approach facilitates reverse ball shoulder replacement without pectoralis major or subscapularis muscle division.
• This technique offers an alternative to traditional methods that necessitate rotator cuff incision.
• Potential benefits include improved shoulder deltoid preservation.

Conclusions:

• A viable surgical approach for reverse shoulder replacement without pectoralis major or subscapularis incision is presented.
• This method may offer advantages in preserving shoulder anatomy and function.
• Further research should evaluate the clinical outcomes and long-term efficacy of this technique.
