Summary
A lateral ankle dislocation without fracture in a 34-year-old woman healed well with closed reduction and casting. Full, pain-free ankle function was restored within a year, despite generalized ligamentous laxity.
Area of Science:
- Orthopedics
- Sports Medicine
- Traumatology
Background:
- Ankle dislocations, though less common than fractures, present unique management challenges.
- Rotatory ankle dislocations require prompt diagnosis and appropriate reduction techniques.
Observation:
- A 34-year-old female patient presented with a closed lateral rotatory ankle dislocation without associated fracture.
- Initial treatment involved closed reduction and subsequent immobilization in a cast for six weeks.
Findings:
- Post-immobilization, the ankle was clinically stable, with normal stress radiographs compared to the contralateral limb.
- One-year follow-up revealed a complete, pain-free, and stable range of motion.
- Generalized ligamentous laxity was noted, potentially predisposing the patient to recurrent talar subluxation.
Implications:
- Non-operative management can be effective for select ankle dislocations without fractures.
- Generalized ligamentous laxity is a critical factor to consider in the assessment and management of ankle instability.
- Successful outcomes are achievable with appropriate conservative treatment, even in cases with underlying laxity.
