Treatment of osteoporotic distal femur fractures with less invasive stabilizing system (LISS) and high strength injectable graft]
China Journal of Orthopaedics and Traumatology(2010)
Abstract
To evaluate the clinical results of less invasive stabilizing system (LISS) and high strength injectable graft in the treatment of osteoporotic distal femur fractures.From Feb. 2005 to Feb. 2008, 26 cases (15 males, 11 females) of osteoporotic distal femur fractures were treated with less invasive stabilizing system (LISS) and high strength injectable graft. The mean age of the patients was 68.5 years (ranging from 59 to 81 years). According to AO classification,there were 9 cases type A3, 6 cases type C1, 7 cases type C2, 4 cases type C3.The mean operation time was (110 +/- 15) min (ranging from 90 to 135 min). The patients were followed-up for from 12 to 28 months (averaged 18 months). The mean healing time was 20.5 weeks(ranging from 16.5 to 28 weeks). No deep infection, fixation loosening, breakage or failure of implants were observed after the operations. According to Rasmussen radiological evaluation,the results showed 19 cases for "excellent", 7 cases for "good". One year postoperatively, the mean ROM of the knees was 2 degrees to 125 degrees, the HSS knee score was from 59 to 99 points with average of (86.5 +/- 8.2) points. According to HSS scoring system, the results showed 22 cases for "excellent", 2 cases for "good", 1 for "fair" and 1 for "poor".The less invasive stabilizing system (LISS) and high strength injectable graft is an effective way for the treatment of osteoporotic distal femur fractures.
