Summary
Talar osteonecrosis, a rare complication, can occur after calcium phosphate injections (subchondroplasty) in the talus, even with ligament repair. This case series highlights the need for awareness and further research into talus subchondroplasty safety.
Area of Science:
- Orthopedic surgery
- Foot and ankle procedures
- Bone healing and complications
Background:
- Talar osteonecrosis is commonly associated with talar neck fractures.
- Complications after foot and ankle procedures are less frequently reported.
- Calcium phosphate subchondroplasty is a newer procedure for talar defects.
Observation:
- This study presents five cases of talar osteonecrosis.
- These cases occurred after talus subchondroplasty, with or without lateral ligament repair.
- The procedures were performed at an institution other than the reporting center.
Findings:
- Talar osteonecrosis is a potential complication following calcium phosphate injection into the talus.
- The occurrence was noted even when combined with acute lateral ligament repair.
- This represents a rare but significant adverse outcome.
Implications:
- Clinicians should be aware of the risk of talar osteonecrosis after subchondroplasty.
- Further research is necessary to evaluate the safety and efficacy of talus subchondroplasty.
- This finding may influence future treatment protocols for talar pathologies.
