RESUMEN
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.
