Geometrical Model Creation Methods for Human Humerus Bone and Modified Cloverleaf Plate

In the field of orthopaedic surgery, for the treatment of bone fractures orthopaedic surgeons use external and internal fixation methods, or combination of these two techniques. Geometrical 3D models of internal fixation implants and human bones are being created by various computer based methods and technical features. These methods include application of computer visualisation techniques like Medical Imaging, Computer-Aided Design, Finite Element Analysis, etc. This paper introduces newly developed methods for the creation of surface model of human humerus and parametric model of the modified cloverleaf plate. The geometrical properties and shape of the parametric model can be customized to match the morphology of humerus bone of the specific patient, by the application of parameter values acquired from medical images (X-Ray or Computerized Tomography). Such implant models can improve pre, intra, and post operative procedures in ortophedic surgery.
