title: Transfixed condylar plate (TCP) provides better biomechanical and weight bearing possibilities for the fixation of trochanteric fracture.
abstract: The goal of this research was to find the implant which would provide a better possibility of the fractured osteoporotic bone weight bearing after trochanteric fracture fixation. The authors constructed a new implant based on the conventional condylar plate, as part of a stabile triangular system. Because of the special oblique form of the screw which absolutely stabilizes vertical and horizontal arm of the plate, this plate was named the transfixed condylar plate (TCP). Analysis showed 6 kN of tolerant loading elastic in TCP with a longer horizontal arm, while this value in the conventional condylar plate was 2.5 kN. Also, dynamic resistance was 2.4 times higher in TCP then in the control model. These improved biomechanical results of this plating fixation system are expected to be found in the clinical use of this plate. This would enhance an early rehabilitation and a better functional outcome.
