Abstract
Bone scintigraphy was performed before or after osteosynthesis or both in 11 children aged 9 to 14 years with femoral neck fractures. the role of bone scintigraphy in predicting development of femoral head necrosis with subsequent collapse was studied. Scintigraphy was not a useful study for this purpose. the explanation of this may be that reposition and osteosynthesis jeopardize the blood supply to the femoral head and invalidates the findings at the pre-operative scan. the childhood femoral head also has a strong potential for revascularization and complete reconstruction of the necrotic bone
