Scintigraphy in nontraumatic femoral head necrosis [PDF]

Acta Orthopaedica Scandinavica, 1987
We performed serial 99mTc-MDP bone scintigraphy of nontraumatic femoral head necrosis in 14 hips of 10 patients. The uptake of isotope was decreased in the very early stage, and either variable or increased at the stage when symptoms appeared. A variable uptake changed to increased uptake in 3 of 10 patients, but there was no hip in which an increased ...
