Bony Exostosis (Osteochondrosis )
Most common bone tumor in children
Solitary or Multiple
Aberrant cortical overgrowth adjacent to growth plate leading to eccentric bony growth
disturbances of growth plate development or localized bone disturbances
First type
HME - AD inheritance
MED - AD inheritance
Dsyplasia Epiphysealis Hemimelica (Trevor Disease ) occurs in infants and young children
second type
Fibrous dysplasia
Management
X-ray characteristic
CT scan - of pelvis , shoulder and spine
MRI
1. assessing continuity of parent bone with cortical and medullary bone in an
osteochondroma
2. catiliage cap size ,
3. impingement syndrome ,
4. and arterial and venous compromise
Angiogram
AV compression
Treatment
Solitary - Symptomatic
very large - avoid in skeletally immature (restricts growth )
Multiple - treatment of symptomatic ones
Angular deformity
timed hemiphyseal stappling
corrective osteotomy
surgical decompression of neurovascular compromise
