Among 280 patients with femoral neck fractures 46 were classified as having impacted fractures according to the criteria mentioned below. The treatment of patients with impacted femoral neck fractures was determined to be mobilization with partial weight-bearing from the first day of admission. Among the 42 patients successful in immediate mobilization there were eight whose fractures disimpacted. Three cases of avascular necrosis were recorded but no cases of non-union. In order to determine the predictive signs of secondary dislocation the X-ray findings were subjected to statistical analysis. The inclination of the fracture line, dislocation into a valgus or varus position and the presence of retroversion did not influence the tendency to disimpaction. More than 80 per cent of the fractures healed without disimpaction.
在280例股骨颈骨折患者中，根据以下标准，46例被归类为嵌插骨折。嵌插型股骨颈骨折患者的治疗方案确定为自入院第一天起进行部分负重活动。在42例立即成功活动的患者中，有8例骨折出现了断端分离。记录到3例缺血性坏死，但无骨不连病例。为了确定继发性脱位的预测征象，对X线检查结果进行了统计分析。骨折线的倾斜度、向外翻或内翻位的脱位以及存在后倾均不影响断端分离的倾向。超过80%的骨折愈合时未发生断端分离。
