Summary
Nonosseous subtalar coalition in children often involves fibrous bridges posterior to the sustentaculum tali. Early diagnosis via computed tomography is crucial for effective hindfoot treatment.
Area of Science:
- Orthopedics
- Pediatric Orthopedics
- Foot and Ankle Surgery
Background:
- Nonosseous subtalar coalition can present with subtle hindfoot abnormalities.
- Accurate diagnosis is essential for appropriate management in pediatric patients.
Purpose of the Study:
- To identify common anatomical locations of nonosseous subtalar coalition in children.
- To emphasize the role of computed tomography in diagnosing this condition.
Main Methods:
- Surgical findings in 11 children with confirmed fibrous bridges were analyzed.
- Clinical and radiographic data from 14 children undergoing conservative treatment were reviewed.
Main Results:
- A common site for nonosseous subtalar coalition was identified posterior to the sustentaculum tali.
- Fibrous bridges were confirmed intraoperatively in a significant cohort.
Conclusions:
- Nonosseous subtalar coalition frequently occurs posterior to the sustentaculum tali.
- Computed tomography is vital for detecting subtle hindfoot changes indicative of coalition.
