Reverse less invasive stabilization system for treatment of femoral intertrochanteric fracture / 中华创伤杂志

ABSTRACT

Objective To evaluate the clinic effect of reverse less invasive stabilization system (LISS) in treatment of femoral intertrochanteric fracture.Methods The study enrolled 22 cases of femoral intertrochanteric fractures treated with reverse LISS from January 2007 to January 2011.Twelve out of the cases were males and 10 were females,with age ranging from 44 to 86 years (mean,72.5 years).Left fracture occurred in 8 cases and right in 14 cases.Causes of injury included fall on the ground in 15 cases,vehicle accidents in 4 cases,and fall from height in 3 cases.There were 15 cases of type Ⅲ and 9 of type Ⅳ according to Evans-Jensen classification and all fractures were closed injuries.Time from injury to operation was 3-14 days (mean,5.3 days).Results Intraoperative hemorrhage was (130.5 ± 60) ml and operation time was (55 ± 15) min.All cases were followed up for 12-30 months (mean,14.8 months).Fracture healing time was 10-27 weeks (mean,13.4 weeks).Harris hip score was excellent in 11 cases,good in 8,fair in 2,and poor in 1,with excellent and good rate of 86％.Two cases felt greater trochanter pain at follow-up ; one presented with plate breakage and malunion at 6 months postoperatively,but may need no further treatment; the rest healed without complications of surgical site infection,varus deformity of the hip,implant breakage,fracture redisplacement,screw drawing pullout or cutout.Conclusion Reverse LISS plating is an effective treatment for femoral intertrochanteric fractures,but the procedure can not assure 100％ success.
