We have evaluated the circulation of the femoral head after multiple pinning for femoral neck fractures by bone SPECT. Forty-four patients (33 women, 11 men, who had a mean age of 67 years) were enrolled prospectively. Early and late bone SPECT images were obtained on 2 to 13 days and 3 months after surgery and follow-up periods were over 12 months (average, 29 months).Introduction
