Summary
Pure ankle dislocations, often caused by motor vehicle accidents in young males, can achieve good outcomes with lateral ligamentous repair. Most patients reported excellent results and no instability post-surgery.
Area of Science:
- Orthopedic Surgery
- Traumatology
Background:
- Pure ankle dislocations (without fracture) are rare injuries.
- These injuries predominantly affect young, active individuals.
Purpose of the Study:
- To evaluate the outcomes of surgical management for pure ankle dislocations.
- To identify prognostic factors and long-term results in this patient cohort.
Main Methods:
- Retrospective review of 14 patients with pure ankle dislocations from 1980-1991.
- Surgical intervention focused on lateral ligamentous repair in 12 patients.
- Follow-up ranged from 15 to 122 months.
Main Results:
- 13 of 14 injuries were open dislocations.
- 10 out of 12 patients (83%) achieved good to excellent functional outcomes.
- No patient exhibited signs or symptoms of ankle instability post-repair.
- One patient required amputation due to severe soft tissue and neurovascular compromise.
Conclusions:
- Surgical repair of lateral ligamentous structures is effective for pure ankle dislocations.
- Good to excellent outcomes and stability can be expected in most cases.
- Early and aggressive management is crucial, especially in open injuries with neurovascular involvement.
