Abstract

|
The pelvic bone is an important anatomical site for patient-specific bone reconstruction using 3D printing technology. The reconstruction of bone defects in this part is challenging because the pelvic bone must transfer weight to the spine through the hip joint and the sacroiliac joint, as well as the pelvic cavity organs and complex neurovascular structures. Unlike the long bones of the limbs, commercially available bone substitute implants are difficult to use, and even biological reconstructions using autologous bone or allogeneic bone transplantation have several limitations in terms of mechanical strength. In contrast, 3D printing bone reconstruction does not simply output the same anatomical bone defect area but minimizes complications and improves functional recovery by reinforcing or reducing the implant and changing its shape and surface in consideration of the degree and quality of the remaining bone and soft tissue condition. As 3D printing for implant production and utilization is a new technology, academic exchange to share related clinical experiences in various fields is important. The design for 3D printing bone reconstruction is different for each patient and there are infinite possibilities, but some aspects are consistent in terms of basic details and some technical points. Therefore, in this review, we will share clinical cases of patient-specific pelvic bone reconstruction to help in the challenge of 3D printing for bone reconstruction surgery.
