Description:  A cross-disciplinary team at the University of Cincinnati have developed a medical device and process to improve the outcomes from total hip arthroplasty ("THA").

THA or hip replacement surgery is a surgery done to remove a diseased hip joint and replace it with an artificial joint, or prosthesis. Approximately 300,000 total hip replacement surgeries are performed annually in the US and many fail due to malpositioning. Failure of a hip replacement leads to revision surgery. Revision surgery can be a major procedure that requires complex techniques and potentially has higher complication rate than the original replacement surgery. In addition, some patients are not medically able to tolerate such a long and difficult surgical procedure.

The UC team has developed a novel method to create a device to assist surgeons with THA. The device uses patient-specific anatomy to ensure proper positioning of the implant. We have collected data from a promising cadaver pilot study. Our device and procedure will reduce the likelihood of the need for revision surgery and should be applicable to any joint replacement surgery.

The technology is patent pending.
