Abstract
Objective To evaluate clinical effects of 95°angled blade plate(ABP),dynamic condylar screw(DCS)and retrograde intramedullary nail(RIN)used in intemal fixation for distal femoral fractures. Methods Ninety-two cases of distal femoral fractures were included in this study.Their age ranged from 31 to 68 years,with an average of 53.6 years.Of them,22 were treated with 95°ABP,29 with DCS and 41 with RIN.Their functional and radiographic outcomes were collected to compare the differences in bone union time,operation time,intra-operative blood loss,and functional scores according to Kolment rating system. Results They were followed up for 12 to 36 (average,18)months.There was no significant difference in bone union time among the 3 groups(P>0.05),but a significant difference in operation time,intra-operative blood loss and functional scores in favor of RIN(P<0.05).X-ray films showed all fractures got united within 4 months except one case that had used bone cement at fracture site.Refracture occurred 6months postoperatively in ODe patient treated with RIN. Conclusion RIN is superior to the other two fixatom for distal femoral fractures because of advantages of short operative time,less iatrogenic trauma,convenient reduction and rigid fixation. Key words: Femoral fraetures; Fracture fixation; internal; Follow-up studies
