Anomalous multifocal ossification of the os calcis
Clinical Orthopaedics and Related Research
|January 1, 1982
Summary
A rare "bifid os calcis" variation was diagnosed shortly after birth, differing from typical cases found in older children. This unusual chondro-osseous maturation highlights normal foot development variations.
Area of Science:
- Orthopedics
- Developmental Biology
- Radiology
Background:
- Accessory ossicles are common in feet, but major developmental chondro-osseous variations are rare.
- The bifid os calcis is an infrequently reported congenital anomaly of the calcaneus.
Observation:
- A case of bifid os calcis was diagnosed neonatally.
- This contrasts with most reported cases diagnosed in children aged three years or older.
- The condition presented as a solitary, bilateral variation in chondro-osseous maturation.
Findings:
- The primary radiographic finding was punctate ossification in the anterior calcaneal region.
- This represents an unusual pattern of calcaneal ossification center development.
- Fetal foot development involves variations in calcaneal ossification and potential for multiple centers.
Implications:
- Early diagnosis of bifid os calcis is possible, challenging previous assumptions about typical age of detection.
- This case contributes to understanding the spectrum of normal variations in fetal foot and calcaneal development.
- Further research may clarify the etiology and clinical significance of this rare condition.
