Patient-Specific instrumentation

Using technology to improve implant positioning

It is known that the position of both the femoral and the acetabular component of a total hip replacement affects it survival. Positioning can influence range of motion, wear rates and ultimately the length of implant survival. By using pre-operative CT scans, 3D models of the patient's anatomy can be created virtually. These models are then used to plan the operation, determining the implant size, type and positioning. Using the surgical plan, patient-specific instruments such as drilling guides and jigs can be designed and produced. These are 3D printed, sterilised, and used intraoperatively to aid the surgeon in achieving an optimal implant position.
