Summary
This case study details a severe ankle injury involving an osteochondral defect and fracture, successfully treated with surgical fixation. The patient achieved full recovery with no functional limitations nine months post-operation.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Radiology
Background:
- Acute osteochondral defects of the talar dome can occur with ankle fractures.
- Supination-adduction ankle fractures are associated with significant ligamentous and articular injuries.
Observation:
- A patient presented with an acute osteochondral defect in the lateral talar dome.
- Radiographs revealed the defect, while MRI showed a stage IV lesion with fragment inversion.
- Associated injuries included lateral ankle ligament rupture and a comminuted medial malleolus fracture.
Findings:
- The osteochondral lesion was successfully treated with surgical reduction and fixation using bioabsorbable pins.
- The patient experienced a complete recovery with no functional limitations at nine months post-surgery.
Implications:
- This case highlights the importance of thorough imaging in diagnosing complex ankle injuries.
- Surgical intervention for talar dome osteochondral defects can lead to excellent functional outcomes.
- Bioabsorbable fixation offers a viable option for managing talar dome fractures.
