A novel reverse hip implant system shows promise in boosting hip stability after total replacement surgery, orthopedic device company Hip Innovation Technology said July 20.
The company said phase one data from its research suggested that patients who used its system showed a higher likelihood of long-term hip replacement success.
"Instability following total hip arthroplasty is a common mode of failure," Dr. Thomas Turgeon, MD, lead investigator and director of arthroplasty research at Canada's Concordia Hip and Knee Institute, said in a news release from Hip Innovation Technology. "The reverse hip replacement system is designed to increase stability at the extremes of motion, and to offer a potentially more forgiving implant positioning without reducing range of motion. The clinical outcome metrics we have observed thus far are consistent with well-functioning hip replacement, and support the stability of this novel implant device."
Dr. Turgeon and his team reported their findings at the Canadian Orthopaedic Association's annual meeting last month. It was based on 22 patients who were implanted with the reverse hip replacement system. Over a 24-month period, they reported that those patients showed significant improvements in hip and pain recovery.
The reverse hip replacement system differs from existing total hip replacement systems by placing the ball on a trunnion within the acetabular cup instead of within the femoral stem, according to a news release from Hip Innovation Technology.
