A PATIENT-SPECIFIC GUIDE FOR REPAIRING THE PELVIC BONE DEFECTS DEPENDING ON BONE QUALITY IN FIXING ARTIFICIAL HIP JOINT SURGERIES

摘要

This invention relates to a patient specific guides for hip replacement for patients who going to hip replacement surgery. The guide works for correction of the acetabulum defects based on a finite element model, which detect the bone quality and guide the surgeons for the optimum screws trajectories. The guides surface reflect the acetabular morphology which provide a correct posting of the cup, especially for the complex case as bone lost, severs fractures and tumors. CT-scan images are using to construct the 3D model of the acetabulum bone, therefore a finite element and virtual surgery planning methods are applied to create the electronic file of the patient specific guide. In finial step the 3D printers are using to produce the patient specific guide.
