Early outcome of a modular femoral component in revision total hip arthroplasty JOURNAL OF ARTHROPLASTY Kang, M. N., Huddleston, J. I., Hwang, K., Imrie, S., Goodman, S. B. 2008; 23 (2): 220-225

Abstract

Forty-six hips in 42 patients underwent revision surgery with a modular femoral component (ZMR; Zimmer, Warsaw, Ind). Thirty-nine hips with 2 to 5 years' follow-up were evaluated radiographically and clinically by the Harris hip score and WOMAC pain/stiffness/function scores. The Harris hip score improved from 47.4 to 72.3 (P<.001), with significant improvements in the WOMAC pain/stiffness/function scores. The mean subsidence was 4.4 mm, with 5 hips demonstrating significant subsidence of more than 5 mm. Four hips required reoperation, 1 due to failure of the femoral component. No early complications were encountered regarding the modular junction. Modular, cementless, extensively porous, coated femoral components have demonstrated early clinical and radiographic success. Distal intramedullary fit helps ensure initial stability; proximal modularity further maximizes fit while optimizing hip offset and length.
