Orthopedic Digital Planning for Total Hip Arthroplasties

Modern joint replacements in orthopedic surgery allow to restore locomotion. More than 150,000 hip replacements are performed each year in France . The optimization results going restoration of the lengths of members and anatomy .

Preoperative planning of hip replacements optimizes the return of the hip rotation center . Preoperative planning of hip prothesis is practiced by layer on radiographs whose scaling is imprecise . The recent TraumaCad system ( Brainlab® ) allows adjustment of the scales for each patient and the virtual positioning of implants to simulate the response to the return of geometric parameters of the hip.

Preoperative planning by TraumaCad hip arthroplasties provides better restitution of limb length over conventional planning methods.

The standardized radiographs being the investigators want to compare this group with a control group operated without TraumaCad planning and evaluating the accuracy of the software to predict implants sizes also .

There is no risk to the patient with this procedure . The direct benefit is increased accuracy of surgical gesture to the patient and the reduction of mechanical problems related to leg length . Earnings for the orthopedic community is the postoperative evaluation. In the long term , the prosthetic technical improvement must increase the life of prostheses with therefore lower revisions and less expenditure in terms of public health.
