Summary
Transient postfracture cysts in children are rare, asymptomatic lesions near greenstick fractures. These cystlike cortical defects typically resolve completely without impacting fracture healing.
Area of Science:
- Pediatric Orthopedics
- Pediatric Radiology
- Pediatric Bone Health
Background:
- Greenstick fractures are common in children.
- Cystlike cortical defects adjacent to fractures are occasionally reported.
- The pathogenesis and natural history of these lesions require further elucidation.
Observation:
- Two new cases of transient postfracture cysts are presented in children with distal radius greenstick fractures.
- Lesions appeared proximal to the fracture line, within subperiosteal new bone.
- The patients were aged 2.5 and 5.5 years.
Findings:
- These cystlike defects are typically asymptomatic.
- Complete resolution of the lesions is the usual outcome.
- No adverse effects on fracture healing were observed.
Implications:
- Transient postfracture cysts are a benign finding in pediatric fractures.
- Understanding their pathogenesis may clarify bone healing mechanisms.
- Further case reports can aid in defining the natural history of these rare lesions.
