The use of proximal fixed modular stems in revision of total hip arthroplasty.
Proximally fixed femoral stems in revision of total hip arthroplasties (THAs) have had inconsistent results. Our aim was to determine the safety and efficacy of a new proximally fixed modular stem in THA revision. Fifty-three patients underwent THA revision with the Exactech AccuMatch M-Series (Gainesville, Fla) modular stem and were followed up prospectively for an average of 2.5 years with preoperative and postoperative Harris Hip Score and SF-12 scores. A small number of complications were reported. One stem was revised within 4 weeks due to subsidence. No later mechanical failure cases were reported. Postoperative Harris Hip Score and SF-12 improved significantly. The use of this modular stem system appears to be safe and efficacious regarding fixation and function in the short term.
