Background: The depth of bolt in Femoral neck system (FNS, DePuy Synthes, Oberdorf, Switzerland) is difficult to finely control as the length of the bolt is in units of 5 mm. Thus, this study introduces a method to control the depth of FNS bolt in analogue scale in patients with femoral neck fracture. Methods: By the technique of control of reaming and retraction of bolt, the tip of implant could be positioned close to subchondral bone without harming it. The position of implant tip in four cases who was operated with the introduced technique was compared to that of eight cases with standard technique.Results: The average tip-apex distance measured in the group that underwent surgery with the technique suggested in this study was statistically significantly shorter than that in manufacturer guide group (p |
