Predictive clinical value of scintigraphical classification of the femoral head in intracapsular fracture of the femoral neck, as classified by Hirano, et al. in 1987, was investigated by long-term follow-up (mean; 4 years and 7 months). Normal healing was achieved in 21 of 24 patients. In those cases, early 99mTc-MDP scintigraphy revealed an over-all increase of radionuclide uptake (Type A) and band-like decrease along the fracture (Type B1). Late segmental collapse of the femoral head was found in 3 patients who showed either a decrease in the weight-bearing area (Type B2) or over-all decrease of radionuclide uptake (Type C). The results of fracture healing were well correlated to each type of scintigraphical classification. The changes of radionuclide uptake in the fracture site were also followed by serial 99mTc-MDP scintigraphy.
通过长期随访（平均4年7个月），对平野等人于1987年分类的股骨颈囊内骨折中股骨头闪烁显像分类的预测临床价值进行了研究。24例患者中有21例实现了正常愈合。在这些病例中，早期99mTc-MDP闪烁显像显示放射性核素摄取总体增加（A型）以及沿骨折线呈带状减少（B1型）。3例患者出现股骨头晚期节段性塌陷，这些患者表现为负重区减少（B2型）或放射性核素摄取总体减少（C型）。骨折愈合结果与每种闪烁显像分类类型密切相关。骨折部位放射性核素摄取的变化也通过连续的99mTc-MDP闪烁显像进行跟踪。
