Plate-screw-wiring technique for the treatment of periprosthetic fracture around the hip: a biomechanical study. Journal of the Medical Association of Thailand. 2001 Jun; 84 Suppl 1(): S415-22http://imsear.searo.who.int/handle/123456789/44076Chotmaihet Thangphaet.Biomechanic properties, bending stiffness and torsional strength, were determined in three different fixation techniques including lateral plating, lateral plating with cerclage wires, and 90 degrees-90 degrees anterior and lateral plating employed in treatment of the femoral shaft fracture with the presence of a femoral prosthesis. Five pairs of human femora with a man made cemented periprosthetic Johansson et al fracture classification type II were used in the experiments. The study showed that 90 degrees-90 degrees anterior and lateral plating produced the best increment in both biomechanic properties. In clinical practice, most of the soft tissue around femoral bone had to be dissected to do this technique, which would affect bone healing. Further study regarding the other properties, benefits, and disadvantages of these three techniques should be conducted before selecting the best method for treatment of the patients.engAdultAnalysis of VarianceBiomechanicsBone PlatesBone ScrewsCadaverEquipment Failure Analysis --methodsFemaleFemoral Fractures --physiopathologyFracture Fixation, Internal --instrumentationHip Prosthesis --adverse effectsHumansMaleMiddle AgedProbabilityProsthesis FailureRange of Motion, ArticularSensitivity and SpecificityTensile StrengthIn Vitro
