The Distance to Dislocate: Refining the Glenoid Track and Considerations for Decision-Making

Video Transcription

Video Summary

Albert Lin discusses refining treatment of shoulder instability by evaluating distance to dislocation (DTD) and glenoid track concepts. He highlights that traditional binary on/off-track assessments overlook nuances; instead, DTD as a continuous measure better predicts failure risk, especially near-track lesions under 10mm DTD. Contact athletes and hyperlax patients show higher failure rates even with larger DTDs, suggesting arthroscopic Bankart alone may be inadequate. Adding remplissage reduces recurrence, especially in high-risk groups with critical humeral bone loss. Lin presents a PIT scoring system combining risk factors to guide treatment decisions, emphasizing personalized approaches rather than one-size-fits-all protocols for shoulder stabilization.
