“…This technique has been evaluated with 0.5-1 mm translation error and 1-1.5 ° orientation error (YAO et al, 2000), and another group obtained errors of 2 mm and 1 ° (GuEZIEC et al, 1998). There is therefore interest in a sufficiently accurate intra-operative registration procedure, without pins, that compromises the complexity, safety or length of the surgical procedure as little as possible (JOSKOWICZ and TAYLOR, 2001). Given these constraints, the most promising solution seems to be touch-based registration, in which the robot itself acquires information about bone geometry by touching a series of reachable points on the bone surface.…”

The aim of the paper was to investigate whether accurate, point-based registration of the intra-operative femur will be achieved within the context of minimally invasive surgery for total hip replacement. Computer tomography images, collected for pre-operative planning purposes, were used to simulate the intra-operative registration procedure using algorithms for various levels of measurement noise, different small areas of the femur available to the surgeon, and a limited number of collected data points (20-60). This helped with the choice of design variables to perform in vitro registration on a plastic bone model to validate the procedure, which included a multistart algorithm developed for intra-operative registration. The algorithm minimised the distance between the measured and image-derived surfaces and was able to cope with the presence of multiple local minima given sufficient computational effort, even with realistically large measurement noise. It was found that, if a small patch of the femur was used, accessible by a needle that could at times penetrate thin layers of soft tissue, errors in the order of 1.0 mm in translation and 0.5 degrees in rotation were achievable.

“…In orthopaedic applications, such as total hip or knee replacement surgery, computer navigation systems use 3D digital models during pre-and intraoperative planning. These systems employ dedicated software applications known as 'surgical planners' (Joskowicz and Taylor 2001;Sato et al 2004;Holly 2006) to help surgeons place prosthetic components precisely and accurately. The digital representations of the anatomical structures needed for these applications are generated by evaluating data volumes from computer tomography or magnetic resonance or by manual or semiautomatic elaboration of medical images such as fluoroscopy projections and X-ray images (Mahaisavariya et al 2002;Kim et al 2004;De Momi et al 2005).…”

At present, computer assisted surgery systems help orthopaedic surgeons both plan and perform surgical procedures. To enable these systems to function, it is crucial to have at one's disposal 3D models of anatomical structures, surgical tools and prostheses (if required). This paper analyses and compares three methods for generating 3D digital models of anatomical structures starting from X-ray images: parametric solid modelling/reconfiguration, global shape modelling and free-form deformation. Seven experiences involving the generation of a femur model were conducted by software developers and different skilled users. These experiences are described in detail and compared at different stages and from different points of view.
