Table 4.
Overview of geometric bone and implant models available for subjects JW and DM. Bone models for were obtained from a subject of similar stature (JW) or from pre- and postoperative CT scan data (DM). Implant component models were obtained by laser scanning. Implant-bone models with implant components properly positioned and oriented on their respective bones were creating using each subject’s post-operative CT scan data. See Lin et al.6 for further details.
