OBJECTIVETo study clinical effects of inversive LISS(less invasive stabilization system, LISS) plate for the treatment of intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures.

METHODSFrom January 2012 to January 2015, 24 patients with intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures were treated with inversive LISS plate, included 16 males and 8 females with an average age of 62.5 years old ranged from 35 to 81 years old. There were 8 cases of traffic accident injuries, 3 cases of falling from high place, and 13 cases of falls injuries. The time from injury to operation was ranged from 2 to 12 days with an average of 5.2 days. The operation time, intraoperative blood loss and the length of hospitalization were analyzed. The fracture union was assessed by follow-up radiographs and hip functional recovery by Harris hip scoring.

RESULTSAll patients were followed up for 16.2 months (ranged, 18 to 36 months). The mean operative time was (68.22±48.36) min;the mean blood loss was (256.28±182.46) ml;the mean time of hospitalization was(14.8±5.2) days. There were no complications such as deep infection, deep vein thrombosis, pulmonary embolism and bone nonunion during the follow up period. The bone healing was ranged from 3 to 8 months with an average of 4.8 months. The mean Harris score was 76.49±12.28 at the final follow-up, 15 cases were classified as excellent, 6 as good and 3 as fair.

CONCLUSIONSInversive LISS plate can be used in treating with intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures, and should not emphasis on premature loading.
