Paper Abstract

For preoperative planning of corrective hip osteotomy, quantitative assessment of the coverage and congruency of the femoral head is essential. Based on serial CT-sections, a computer-assisted method has been developed providing for three-dimensional modelling of the in vivo situation and subsequent evaluation of the hip joint. The cartilage structures extracted from each cross-section are triangulated and reconstructed into surfaces. New algorithms were developed to cope with the problems caused by the contour data structures. They include the automated connection of open and closed contours, contour bifurcations and capping of terminating contours. Surgical procedures are simulated using the surface data and a quantitative evaluation of the coverage and centering of the hip joint is achieved. The tiling method presented is not limited to CT-data and can be applied to other structures analyzed with contours.
