    Abstract:

    In this paper, we introduce a development of clinical L steel plate since 1994 year, which useddevice for the interfixation of unstability fracture 60 cases in the intertrochanteric hipfractures.Sixty cases were treated in this manner, a long-term follow-up 25 months in average revealedoverall excellent results. Bone union was obtained in 8.9 weeks with satisfaxtory function of thelimbs in all patiebts. We examined the effect of the L steel plate on strain and displacent in theproximal femur, using eight cadaver femora instrumented with six strain gauges along the medialand lateral cortices. Before and after experimentally created two-part and four-part fractures. Strainpatterns and screw motion were compaerd. With previously obtained values for a sliding hip screwdevice. the biomechanical characteristics of the two devices were loaded to 1800N.Experimentalresults showed, the L steel plate appear to offer distinct biomechanical adventage over the SHS inthe treatment of unstable intertrochanteric fractures.
