In orthopedic surgery, computer-assisted support systems have gained significant importance in the  post-traumatic reconstruction of bone anatomy. The precise pre-operative planning of such interventions is one of the major prerequisites for a successful intervention. Unfortunately, the accurate pre-operative assessment of complex injuries can be difficult due to the lack of reliable planning tools.

This book aims at improving the pre-operative planning for two types of orthopedic interventions of the upper limb, namely the reconstruction of complex humerus fractures and the surgical correction of deformed forearm bones.

Firstly, a bone segmentation and separation framework based on graph cut optimization with novel energy functions is presented. The framework allows the extraction of bone anatomy from computed tomography images in a generic way. Thereafter, two approaches for the virtual reconstruction of complex proximal humerus fractures are discussed. Interactively, the reconstruction is carried out in an immersive, multi-modal planning system integrating stereoscopic rendering and haptic feedback. The second approach targets fracture reconstruction in an automatic fashion which is an extremely challenging task. Finally, computer-assisted tools are presented to improve the planning of corrective interventions of the forearm. These methods include registration-based and landmark-based algorithms, enabling the more accurate quantification of deformities in 3-d. A major focus was put on the pre-operative simulation of functional effects by introducing a novel kinematic model of the rotational forearm motion.

Philipp Fürnstahl obtained his M.Sc. (Dipl.-Ing.) degree in Technical Mathematics and Information Technology from the Technical University Graz, Austria, in 2005. From 2006 to 2010, he was research assistant and Ph.D. student at the Computer Vision Laboratory of ETH Zürich, Switzerland. In 2010, he finished his doctoral thesis entitled "Computer-Assisted Planning for Orthopedic Surgery" and was awarded a Ph.D. degree (Dr. sc. ETH Zürich) from ETH Zürich.
