- The longitudinal flutes provide rotational stability and promotes osseointegration, Garbuz said.
KOLOA, Hawaii — The Wagner cone prothesis in total hip arthroplasty for patients with difficult anatomy can provide high patient satisfaction and excellent functional outcomes and component survivorship, according to a speaker here.
“You won’t use this a lot, but if you’re doing a lot of hip surgery, this is a good stem to have in your armamentarium,” Donald S. Garbuz, MD, MHSc, FRCSC, professor and head, division of lower limb reconstruction, department of orthopaedics at the University of British Columbia, said at Orthopedics Today Hawaii.
Garbuz said the Wagner cone prosthesis, manufactured by Zimmer Biomet, is a diaphyseal-engaging stem with a 5-degree taper and cylindrical cross-section area. Its longitudinal flutes provide rotational stability and promotes osseointegration, he said, and the smallest outer diameter is 13 mm.
“It’s not a lot of cases every year – certainly of the order [of] 2%, 3%. But we keep it on the shelf, and it's good to have it when you need it,” Garbuz said.
Garbuz said he and colleagues recently published midterm outcomes of 320 cases in a young patient population. Mean follow-up was 10 years, and the study endpoint was revision.
“We had almost 98% survivorship at 10 years. When these ingrow, they really ingrow,” Garbuz said.
