We review here our experience in the computer-aided design and manufacture and implantation of custom-made hemipelvic prostheses in 10 patients who underwent internal hemipelvectomy for extensive pelvic lesions. Computed tomography data and the rapid prototyping technique were used to make a precise model of each patient's pelvis for the simulated hemipelvectomy; the model was used to design and manufacture prostheses that were easy to implant because the location and orientation of the acetabulum was readily adjustable. Four patients died 6 to 10 months after surgery; the remaining 6 patients, monitored for 21 to 48 months, all had good hip function. There were early hip dislocations in 2 patients and wound-healing problems in 3, but all were treated successfully.
