Application of self-made fine-tuning device in distal locking process of femoral interlocking intramedullary nail

Abstract

To evaluate the curative efficacy of self-made fine-tuning setting in the process of femoral distal implantation of intramedullary nail. From October 2015 to October 2017, 66 cases of femoral shaft fracture were treated with anterograde interlocking intramedullary nail including 45 males and 21 females with a mean age of(37.21±11.18) years old. Among them, 36 cases were treated with the manufacture's aiming device and self-made fine-tuning setting (research group), other 30 cases were treated with the manufacture's aiming device(control group). The mean operation time, the times of C-arm scan in surgery, the post-operation complications and the fracture union were observed and compared in two groups. Sixty-two cases acquired 8 to 15 months with a mean time of 12.4 months follow-up visit. The post-operation complications and the fracture union between the two groups had no significant difference(P>0.05), the mean operation time and the times of C-arm scan in surgery had statistically significant difference(P<0.05). Self-made fine-tuning setting in the process of femoral interblocking intramedullary nail could shorten operation time and reduce the the times of C-arm scan.
