3D Reconstruction of Patient Specific Bone Models for Image Guided Orthopaedic Surgery
type: CreativeWork
description: Visualisation of patient-specific fractured bone in 3D plays an important role in image guided orthopaedic surgery. Existing research often focuses on intra-operative registration of the patients' anatomy with pre-operatively obtained 3D volumetric data (e.g. CT scans) utilising fiduciary markers. This expensive and invasive approach is not routinely available for diagnostics, and a majority of fracture reduction procedures currently solely relies on 2D x-ray/fluoroscopic images. This research aims to assist orthopaedic surgeons in all steps of the femur fracture reduction procedure by introducing 3D anatomical visualisation. Studies conducted on femur fracture reduction has confirmed that computer-aided systems can significantly improve the accuracy of orthopaedic procedures by augmenting the current 2D image guidance with an interactive display of 3D bone models. This research indicates that the positioning errors, which generate bone misalignments and complications, will be reduced through the introduction of 3D bone fragment visualisation during surgical procedures. Consequently 3D visualisation of anatomy plays an important role in image guidedd orthopaedic surgery and most importantly contributes to minimally invasive procedures. The research goals of this thesis are achieved through the construction of a 3D model of a fractured bone, and the real-time tracking (pose estimation) of the bone segmentsintra operativelyly. The first component of the research is the innovative 3D reconstruction technique proposed for preoperative planning on procedures involving the femur, tibia and iliac. Pre-operative planning plays an essential role in the management of orthopaedic injuries because many of the technical problems that may arise during surgery can be anticipated during this preparatory phase. The novel reconstruction algorithm is based on two conventional orthogonal (in anterior and lateral views) 2D radiographic images and a 3D model of an intact (healthy) bone. …
