Assessment of bone perfusion at the time of injury following femoral neck fracture is important in determining the prognostic success of implanting joint sparing fixation hardware or total hip arthroplasty. Dynamic Contrast Enhanced (DCE) MRI was used to assess perfusion of the femoral head following minimally displaced subcapital fractures of the femoral neck. A statistically significant decrease in uptake (Akep) was seen in the injured versus contralateral side. This indicates the potential utility of this method to assess bone perfusion at the time of injury aiding the clinician in predicting the risk of possible avascular necrosis.
