Summary
A young woman experienced atraumatic anterior hip dislocation during ballet. Surgical hip reduction was successful, with full recovery and return to dancing, avoiding long-term complications like avascular necrosis.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Traumatology
Background:
- Anterior hip dislocation is a rare injury, often associated with high-energy trauma.
- Noncontact atraumatic hip dislocations are exceptionally uncommon, particularly in young, healthy individuals.
Observation:
- A healthy young woman sustained an atraumatic anterior hip dislocation while performing ballet.
- Closed reduction failed due to interposition of the anterior capsule and rectus femoris muscle.
Findings:
- Open reduction via Smith-Petersen approach achieved a concentric and stable hip joint.
- Femoral nerve neuropraxia resolved within six weeks post-surgery.
- Two-year follow-up revealed no avascular necrosis or posttraumatic arthritis.
Implications:
- This case highlights the possibility of atraumatic hip dislocations in noncontact activities.
- Successful open reduction can lead to excellent functional recovery and return to high-level activities.
- Emphasizes the importance of considering soft tissue interposition in failed closed reductions.
