Abstract:
A retrospective and cross sectional study was carried out in 23 cases of Fibrous dysplasia (FD) of bone diagnosed in Musculoskeletal Pathology ward, Traumatic & Orthopedic Center, HCMC, we noticed that Male/female ratio = 1:2.2, the peak age is the 2nd decade Monostolic FD: Pylyostotic FD=12:11. In monostotic FD, the lower limb is most affected (83.3%) in which tibia is the most common bone involved, while polyostotic FD is most encountered in the femur and pelvis. The most common X ray finding is the bone expansion lesion (79.6%), followed by mixtelytic and sclerotic osseous lesions, ground glass aspect (39%). The zone of transition is narrow (77.2%) and sclerotic margin (63.6%) are other common findings. "Crook shepherd" deformity is classic sign in femoral FD.
