Why the study?
Does the operative procedure influence postoperative blood supply of the femoral head as measured by 99mTc-MDP scintimetry in patients with femoral neck fractures?

The operative procedure for femoral neck fractures likely influences the postoperative blood supply of the femoral head in patients with intermediate pre-operative uptake.
May indicate operative effects on femoral head perfusion in intermediate-uptake cases; leaves open scintimetry's role in femoral neck fracture management.
In 22 patients with femoral neck fractures 99mTc-MDP scintimetry was performed before operation and again shortly after operation; in 17 of these patients the investigation was repeated after four months. Six patients with increased uptake in the femoral head before operation and eight with decreased uptake had similar results at the first postoperative investigation. Of eight patients with an intermediate uptake before operation, two showed increased and six decreased femoral head uptake after operation. It is concluded that for the patients in the group with intermediate femoral head uptake before operation, the operative procedure probably influenced the postoperative blood supply of the femoral head.
