The role of preoperative bone scan for determining the treatment method for femoral neck fracture.
To evaluate the role of preoperative bone scintigraphy in determining the operative treatment method for femoral neck fracture, we reviewed the data of 83 patients who underwent preoperative bone scanning after femoral neck fracture. Fractures were classified using the Garden staging system. Radioisotope uptake in femoral heads was evaluated visually. Of 28 patients with Garden stage I or II, radioactivity of the femoral head was normal in 26, partially reduced in one, and generally reduced in one patient. Twenty-seven patients were treated by closed reduction and multiple pinning, and one patient was treated by bipolar hemiarthroplasty. Of 55 patients with Garden stage III or IV, femoral-head radioactivity was normal in three, partially reduced in seven and generally reduced in 45 patients. Fifty-four patients were treated by bipolar hemiarthroplasty or total hip arthroplasty, and one patient was treated by closed reduction and multiple pinning. In only one of the 83 cases was the operative method changed because of bone scan findings. Isotope uptake of the femoral head after femoral neck fracture generally corresponded with the degree of fracture displacement. Preoperative bone scans appear to have no significant role to play in determining the operative treatment method for femoral neck fracture.
