Cleidocranial Dysplasia (Dysostosis)
- autosomal dominant proportionate dwarfism that affects bones formed intramembranously (eg. facial bones, cranium, & clavicles);
- dislocations of hips, knees, and the radial heads may occur;
- most commlonly, absence of the central portion of the clavicle with rudimentary medial and lateral portions remaining;
- may be confused w/ pseurdoarthrosis of the clavicle
- coxa vara:
- consider intertrochanteric osteotomy if varus is < 100 deg;
- Management of developmental coxa vara in cleidocranial dysostosis.
- pubis: shows delayed ossification (hence, it may appear to be widened)
