Injury
|March 1, 1989
Summary
This case report details an isolated dorsal dislocation of the tarsal navicular bone, a rare foot injury. Successful treatment involved closed reduction and percutaneous fixation, with long-term wire retention recommended to prevent arthritis.
Area of Science:
- Orthopedics
- Traumatology
- Podiatry
Background:
- Tarsal navicular bone dislocations are rare foot injuries.
- Dorsal dislocations are particularly uncommon, often associated with significant trauma.
Observation:
- An unusual case of isolated dorsal dislocation of the tarsal navicular bone is presented.
- The injury resulted from hyperextension of the foot.
Findings:
- Closed reduction and percutaneous fixation with a Kirschner wire were performed.
- Immobilization lasted for 8 weeks, with satisfactory initial outcomes.
Implications:
- To prevent redislocation and subsequent arthritis, the Kirschner wire should remain in place for at least 6 months.
- This case highlights the importance of prolonged fixation for stabilizing rare tarsal navicular dislocations.
