Biomechanical analyses of distal radius osteosynthesis

Abstract


In case of complicated distal radius fractures, it is necessary to perform osteosynthesis of individual bone segments in anatomic position. In clinical practice, osteosynthesis is performed either using splints or intramarrow implants. Both of these fixation elements have certain advantages, but also disadvantages for the patient (the operation method, the extent of operation, its length, etc.), which have to be considered by the surgeon when making the choice of fixation element. One of the parameters determining the successful fracture treatment is the stability of the fixation element and individual bone segments under loading conditions. From the clinical practice therefore arose the necessity to perform evaluation of biomechanical stability of distal radius fractures fixated by a splint or an intramarrow implant. To perform such evaluation, a series of computational analyses using the Finite Element Method were carried out.
