Arthroscopic visualization of subscapularis tendon lesions

Area of Science:

• Orthopedic Surgery
• Arthroscopy Techniques
• Shoulder Anatomy

Background:

• Subscapularis tendon lesions can be difficult to visualize during standard shoulder arthroscopy.
• Complete visualization of the tendon's insertion on the lesser tuberosity is often challenging.
• Accurate diagnosis and treatment of subscapularis tears require clear visualization.

Purpose of the Study:

• To describe a novel maneuver for enhanced visualization of the subscapularis tendon insertion during shoulder arthroscopy.
• To demonstrate the utility of this technique for improving diagnostic accuracy and surgical planning.
• To highlight the advantages of this maneuver over existing methods.

Main Methods:

• A specific maneuver during shoulder arthroscopy is detailed.
• The technique utilizes a standard 30-degree arthroscope inserted through the posterior portal.
• Visualization of the subscapularis tendon insertion on the proximal humerus is achieved.

Main Results:

• The described maneuver provides excellent visualization of the subscapularis tendon insertion.
• It allows complete visualization of the intra-articular tendinous insertion.
• Standard transrotator interval portals can be used for subsequent surgical steps.

Conclusions:

• This maneuver significantly improves visualization of the subscapularis tendon insertion.
• It simplifies surgical procedures like debridement, suture passage, and implant insertion.
• The technique eliminates the need for accessory portals, enhancing surgical efficiency.
