Plastic bowing of the femur in a neonate

Area of Science:

• Pediatric Orthopedics
• Pediatric Radiology
• Pediatric Bone Health

Background:

• Acute plastic bowing injuries in children typically show minimal periosteal callus formation.
• These injuries generally have limited remodeling potential in pediatric patients.
• Understanding injury patterns in neonates is crucial for predicting outcomes.

Purpose of the Study:

• To report a case of plastic bowing of the femur in a neonate.
• To investigate the healing and remodeling characteristics of plastic bowing injuries in neonates.
• To compare the remodeling potential in neonates versus older children.

Main Methods:

• Case report of a neonatal femur plastic bowing injury.
• Serial radiographic follow-up to assess bone healing and deformity remodeling.
• Comparative analysis of observed remodeling against known patterns in older children.

Main Results:

• The neonate demonstrated significant periosteal new bone formation.
• Rapid remodeling of the femoral deformity was observed on follow-up radiographs.
• This contrasts with the typical limited callus and remodeling seen in older children.

Conclusions:

• Neonatal plastic bowing injuries of the femur exhibit a greater remodeling potential than in older children.
• Early periosteal new bone formation is a characteristic of healing in these neonatal injuries.
• This case highlights unique healing characteristics in the neonatal population.
