title: [99mTc-MDP abnormal uptake in the femur shaft in hemi-lateral hip joint disorders].
abstract: During the past 4 years, three-phase bone scintigraphy using 99mTc-MDP has been studied in 68 patients suffering from hemi-lateral hip-joint disorders. We were impressed on abnormal uptake of the shaft of femur on the involved side. 99mTc-MDP uptake in the shaft of femur is compared with between involved leg and normal leg of 68 cases with hemi-lateral hip-joint disorders (76 examinations). We excluded cases of osteomyelitis, cases of malignant tumor, and post-operative cases. In early images, the 99mTc-MDP uptake is not always increased in involved side. But in delayed images, there are no patients whose normal side's 99mTc-MDP uptake is increased. The 99mTc-MDP uptake in early image is not related only with blood flow of the thigh but with the amount of soft tissue of the thigh. And the 99mTc-MDP uptake in delayed image is related with disuse osteoporosis.
