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.

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.
