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

ABSTRACT

OBJECTIVE@#To evaluate the curative efficacy of self-made fine-tuning setting in the process of femoral distal implantation of intramedullary nail.@*METHODS@#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.@*RESULTS@#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(>0.05), the mean operation time and the times of C-arm scan in surgery had statistically significant difference(<0.05).@*CONCLUSIONS@#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.
