Summary
This study details an arthroscopic technique for shoulder instability using an iliac crest bone graft and TightRope fixation. It effectively reconstructs glenoid bone loss with minimal invasiveness and preserves rotator cuff integrity.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Arthroscopy
Background:
- Significant glenoid bone loss often leads to shoulder instability.
- Arthroscopic anatomic glenoid reconstruction is an emerging surgical solution.
- Effective techniques are needed to address bone defects and restore shoulder stability.
Purpose of the Study:
- To provide a detailed, step-by-step guide for arthroscopic anatomic glenoid reconstruction.
- To describe the use of an iliac crest autograft with double TightRope fixation.
- To highlight the advantages of this minimally invasive surgical approach.
Main Methods:
- The procedure utilizes three arthroscopic portals (anteroinferior, anterosuperior, posterior).
- An iliac crest autograft is prepared and secured using TightRope and DogBone constructs.
- The graft is introduced arthroscopically, fixed to the glenoid rim, and followed by a Bankart repair.
Main Results:
- The technique allows for all-arthroscopic glenoid reconstruction.
- It preserves the integrity of the subscapularis tendon.
- The method facilitates reliable bone graft union and avoids hardware complications.
Conclusions:
- Arthroscopic anatomic glenoid reconstruction with iliac crest autograft and TightRope fixation is an effective treatment for glenoid bone loss.
- This technique offers a minimally invasive option with preservation of key anatomical structures.
- The described method provides a reliable and reproducible approach to restoring shoulder stability.
