Summary
This study introduces a novel all-arthroscopic surgical technique for treating recurrent shoulder instability caused by bone loss on both sides of the glenoid. The method utilizes two bone grafts to restore glenoid anatomy and stability.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomedical Engineering
Background:
- Recurrent glenohumeral instability is often linked to glenoid bone loss.
- Current surgical treatments for glenoid bone loss typically involve metallic hardware.
- Limited data exist regarding traumatic instability with combined glenoid bone loss.
Purpose of the Study:
- To describe a novel all-arthroscopic surgical technique for addressing bidirectional traumatic glenohumeral instability with bipolar glenoid bone loss.
- To present a technique that avoids metallic hardware fixation.
Main Methods:
- An all-arthroscopic double-bone block cerclage technique was developed.
- Two tricortical iliac crest autografts were used for augmentation.
- The technique addresses instability involving both the anterior and posterior glenoid rims.
Main Results:
- The described technique allows for all-arthroscopic management of bipolar glenoid bone loss.
- It utilizes autografts, potentially reducing complications associated with hardware.
- This method offers a solution for complex traumatic instability cases.
Conclusions:
- The all-arthroscopic double-bone block cerclage technique is a viable option for treating traumatic glenohumeral instability with bipolar glenoid bone loss.
- This technique may offer an alternative to hardware-based reconstructions.
- Further studies are warranted to evaluate long-term outcomes.
