Background: This study aimed to evaluate the treatment effects of reverse Less Invasive Stabilization System (LISS) on femoral intertrochanteric fractures.

Methods: A total of 22 cases with femoral intertrochanteric fractures were treated with reverse LISS. The period from injury to operation was 3-14 days.

Results: The haemorrhage was 130.5 ± 60 ml during the surgery and the operation time was 55 ± 15 min. The fracture healing time was 10-27 W (average 13.4 W). According to the Harris functional scoring, the results were excellent in 11, good in 8, fair in 2 and poor in 1, excellent and good rate of clinical results were 86.4%. 2 cases developed discomforts and pains in greater trochanter. Plate collapse was found in 1 case by X-ray 6 months following surgery. Fortunately, no further treatment was required for fracture malunion. The rest 19 cases had no surgical site infection, no varus deformity of hip, any implant failure and displacement of fracture, no backing out or loosening of the locking screws.

Conclusions: Reverse LISS plate is an effective way for femoral intertrochanteric fractures, although there is certain failure rate. In order to improve the clinical effect, intraoperative normative operation and avoiding early weight bearing are very important.
