A prospective study was undertaken to determine the value of scintigraphy in predicting nonunion or necrosis of the femoral head following femoral neck fractures. Scintigraphy was carried out in 49 patients before operation and in 37 one week after operation; in 18 it was done before and after operation. The uptake of isotope was estimated visually as either normal or reduced compared to the opposite side. All the patients were followed up for at least 2 years. The results indicate that pre-operative bone scintigraphy is useful in elderly patients to predict nonunion and necrosis, and therefore is recommended to select those patients who will benefit from primary arthroplasty instead of fixation of the fracture.
进行了一项前瞻性研究，以确定骨闪烁显像在预测股骨颈骨折后股骨头不愈合或坏死方面的价值。对49例患者在术前进行了骨闪烁显像，37例在术后1周进行了骨闪烁显像；18例在术前和术后均进行了骨闪烁显像。通过与对侧对比，肉眼估计同位素摄取情况为正常或降低。所有患者均随访至少2年。结果表明，术前骨闪烁显像对老年患者预测不愈合和坏死有用，因此建议用于选择那些将从一期关节置换术而非骨折固定术中获益的患者。
