Congenital deformities or wrong post-traumatic healing positions of the forearm bones can cause limitations in the range of motion (ROM) of patients, generate pain, engender instability of the joint and cause aesthetics problems. Anatomical reduction of the affected bones by surgical treatment (osteotomy) is used to achieve the restauration of a normal joint/bone anatomy. Cutting-edge technologies for osteotomy procedures include 3D pre-operative planning of the surgery, virtually performed on patient-specific bone models generated through image segmentation of medical CT.

However, one of the current challenges in preoperative planning is the omission of surrounding muscles, articulations and further soft tissue structures. Inclusion of accurate patient-specific soft tissue information is one of the on-going research areas.

Goal of this student project is the development of a Biomechanical model of the forearm. The project builds upon available 3D models of forearm bones and existing GUI for operation planning, and includes:

  1. Literature research for state-of-the-art in atlas fitting and soft tissue simulation of the forearm, focusing on the interosseous membrane (IOM).
  2. Selection of an (existing) anatomical atlas of the forearm and implementation of deformable registration of the atlas to the patient specific bone data, using similar techniques as presented in [1, 2].
  3. Development of a biomechanical model /simulation of the IOM of the forearm. This part constitutes the main part of the project. The idea is to be able to simulate/analyze the motion of the forearm with the patient specific data, and adapt the previously fitted atlas, focusing on the behavior of the IOM [3-5].
  4. Evaluation and validation of the model through available clinical pre and post-operative data. 

The project will be jointly supervised by the laboratory for Orthopedics Biomechanics of ETH, and the Computer Assisted Research Development (CARD) group at the University Hospital Balgrist. Objectives and scope could be adapted according to the duration of the project. You should have a solid background in computer graphics and be familiar with 3D modelling. Experience in human anatomy and biomechanics are advantageous.
