Proximal Cementing for Revision Hip Arthroplasty
Alfaro-Adrian J., Crawford RW., Wulke A., Murray DW., Mclardy-Smith P.
We report the results of a new technique of proximal cement fixation in 41 patients having revision hip arthroplasty using the Oxford modular femoral component. This consists of two parts, a metaphised wedge and a stem. The metaphyseal wedge is cemented and applies the load proximally to encourage bone healing. The wedge is free to slide on an uncemented stem that gains fixation distal to areas of bone loss, with the intention of reducing the risk of fracture. The clinical and radiographic follow-up ranged from a minimum of 3 years to 7 years. There have been no re-revisions. Ninety percent of the patients had pain or slight pain. Despite a relatively high rate of early subsidence, we feel that our results are encouraging, and justify the continued use of this component in hip revision surgery.
