Thirty-one femoral neck fractures which united without complications (nonunion or late segmental collapse) were included in a prospective sequential scintimetric study. Roentgenologically, three subgroups with different healing rates could be distinguished: rapid union, normal union, and delayed union. All fractures showed a rapid increase in relative femoral head radionuclide uptake after the 1-week scintimetry, followed by a gradual decline after 6 weeks-3 months. However, both the initial rise in activity and the time for maximal uptake tended to differ between the three groups. For rapid union and normal union the peak activity was registered at 6 weeks and for delayed union at 3 months. It is concluded that sequential scintimetric assessment of femoral head uptake can identify different healing rates and that this difference can be partly explained by a transient impairment of vascular supply to the femoral head in fractures with delayed healing.
31例无并发症（骨不连或晚期节段性塌陷）愈合的股骨颈骨折纳入一项前瞻性连续骨闪烁显像研究。从X线角度看，可区分出三个愈合速度不同的亚组：快速愈合、正常愈合和延迟愈合。所有骨折在1周骨闪烁显像后股骨头相对放射性核素摄取均迅速增加，随后在6周 - 3个月后逐渐下降。然而，三组之间初始活性升高及摄取最大值出现的时间往往有所不同。快速愈合组和正常愈合组的峰值活性在6周时出现，延迟愈合组在3个月时出现。结论是，对股骨头摄取进行连续骨闪烁显像评估可识别不同的愈合速度，且这种差异部分可由愈合延迟的骨折中股骨头血管供应的短暂受损来解释。
