Summary
Release of the transverse scapular ligament (TSL) is crucial for suprascapular nerve (SSN) entrapment. This new arthroscopic technique simplifies TSL identification using the scapula
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Nerve Entrapment Syndromes
Background:
- Suprascapular nerve (SSN) entrapment often necessitates transverse scapular ligament (TSL) release.
- Current arthroscopic methods rely on complex landmarks like the coracoid and conoid ligament, requiring extensive tissue removal.
Purpose of the Study:
- To present a novel, simplified arthroscopic technique for TSL release.
- To improve efficiency by utilizing the superior border of the scapula as a primary landmark.
Main Methods:
- The technique employs a lateral viewing portal and anterolateral, SSN, and accessory working portals.
- Dissection proceeds along the supraspinatus anterior border towards the superior scapular border.
- The TSL is identified by palpating a dimpling along the superior border of the scapula.
Main Results:
- This method offers a more direct and potentially faster approach to TSL identification.
- It minimizes the need for extensive fibro-fatty tissue removal compared to previous techniques.
Conclusions:
- The described technique provides an alternative arthroscopic approach for TSL release in SSN entrapment.
- Utilizing the superior border of the scapula simplifies landmark identification, potentially reducing operative time.
