Summary
Closed total talar dislocation is rare, but prompt reduction can lead to excellent outcomes. This case study shows a young patient achieving full, pain-free motion after a bicycle accident, with no signs of avascular necrosis.
Area of Science:
- Orthopedics
- Traumatology
- Sports Medicine
Background:
- Total talar dislocation is an uncommon and severe ankle injury.
- These injuries are frequently open, posing significant challenges for treatment and prognosis.
- Closed dislocations are exceptionally rare, making case reports valuable for understanding management.
Observation:
- A 19-year-old male sustained a closed anterolateral total talar dislocation after a fall from a bicycle.
- The patient underwent immediate closed reduction of the dislocation.
- Follow-up included magnetic resonance imaging (MRI) at 6 months and clinical assessment at 2 years.
Findings:
- The closed reduction was prompt and successful.
- Post-reduction MRI at 6 months revealed no evidence of avascular necrosis of the talus.
- At 2-year follow-up, the patient demonstrated a complete, pain-free range of motion in the ankle and subtalar joints.
Implications:
- Prompt closed reduction is a viable and effective treatment for closed total talar dislocation.
- Early imaging can help monitor for complications like avascular necrosis.
- Successful management can result in excellent long-term functional recovery, even in rare injury patterns.
