Summary
Subtalar dislocations without bone fractures yield good functional outcomes, with no early post-traumatic arthrosis. Medial and lateral dislocations show similar results, indicating good prognosis for these ankle injuries.
Area of Science:
- Orthopedic surgery
- Traumatology
- Sports medicine
Background:
- Subtalar dislocations are severe injuries.
- This study focuses on dislocations without associated bone injuries.
- Evaluating outcomes based on dislocation direction is crucial.
Purpose of the Study:
- To assess functional and subjective results of isolated subtalar dislocations.
- To determine if dislocation direction impacts post-traumatic outcomes.
- To investigate the occurrence of early post-traumatic arthrosis.
Main Methods:
- Retrospective analysis of 56 subtalar dislocations (13 isolated).
- Follow-up averaged 39.8 months.
- American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale used for functional assessment.
- Altman classification for radiological assessment of arthrosis.
Main Results:
- Average AOFAS score was 81.
- 11 patients had good results, 2 had satisfactory results.
- Average range of motion (ROM) was 39.2 degrees.
Conclusions:
- Isolated subtalar dislocations demonstrate good functional and subjective outcomes.
- Absence of bone injuries correlates with no early post-traumatic arthrosis.
- No significant difference in outcomes between medial and lateral subtalar dislocations was observed.
