Computer-Assisted to Personalized Excision of Bone Tumor and Precise Bone Reconstruction

Computed tomography is used in 13 clinic cases with bone malignant tumor to get 2-dimensional data of diseased area. Reconstruction of 3- dimensional anatomical model, excision range of bone, designing of individual surgical template and bone prosthesis was accomplished preoperatively by computers. Based on computer-assisted-design (CAD) proposal, we cut the tumor accurately, and use allografts bone with personalized prosthesis to reconstruct...
