Summary
This case report details an anterior hip dislocation following arthroscopic surgery for femoroacetabular impingement. A mini-open capsulorrhaphy was required to restore hip stability after initial reduction attempts failed.
Area of Science:
- Orthopedic Surgery
- Hip Arthroscopy
- Sports Medicine
Background:
- Femoroacetabular impingement (FAI) is a common cause of hip pain, often treated arthroscopically.
- Arthroscopic FAI surgery involves addressing bony abnormalities and labral tears.
- Complications, though rare, can occur during hip arthroscopy.
Observation:
- A patient with cam-pincer FAI underwent arthroscopic surgery including labral debridement and femoral osteoplasty.
- During the procedure, supranormal hip distraction was used to remove an iatrogenic loose body.
- The patient experienced an anterior hip dislocation in the recovery room.
Findings:
- Initial closed reduction and bracing failed to achieve a stable hip reduction.
- Multiple reduction attempts were unsuccessful, highlighting significant instability.
- A subsequent mini-open capsulorrhaphy successfully stabilized the hip.
Implications:
- This case highlights a rare but severe complication of hip arthroscopy.
- Multifactorial causes involving altered static hip stabilizers are proposed.
- Lessons learned aim to prevent similar iatrogenic hip dislocations in future procedures.
