BACKGROUND:: A new implant has been developed to fix the stable intertrochanteric fractures. OBJECTIVE:: To compare the biomechanical characteristics of self-made minimally invasive proximal femoral plate (SPFP) and dynamic hip screw (DHS) for stable intertrochanteric fractures of the femur. METHODS:: The dry femur specimens were collected and the AO type A1.3 stable intertrochanteric fracture model was created successively and fixed with SPFP and DHS respectively. Then, six varistors were arranged along the internal and lateral cortex in the proximal femur. The compression, bending, shear and torsion were detected after fixation. RESULTS AND CONCLUSION:: After the stable intertrochanteric fractures of the femur was fixed with SPFP, the internal and lateral strength were 13% higher than that after fixed with DHS, and the internal strength was 16% higher, the torsional strength was 18% higher and the torsional stiffness was 31% higher than that after fixed with DHS. There was significant difference between SPFP and DHS fixation (P < 0.05). Compared the biomechanical characteristics of SPFP and DHS, SPFP had distinctive advantages over DHS in anti-tensile, anti-press, anti-rotation and varus ability.Shi M, Li T, Han DF.
