Background: Recently, metal-on-metal hip resurfacing has
enjoyed a resurgence as an alternative to hip
arthroplasty in properly selected patients. The
purpose of the present study was to report the
early results of hip resurfacing through an anterolateral
approach and to describe the technique with
modifications that have been made as experience
with the procedure has increased.
Methods: A total of fifty-seven hip resurfacing
procedures in fifty-three patients were performed
by a single surgeon with use of the Cormet Hip
Resurfacing system through an anterolateral
approach. The results were assessed on the basis of Harris
hip scores, a radiographic analysis, and an
analysis of failures.
Results: After a mean duration of follow-up of
thirty-eight months, the mean Harris hip score
was 99 points. Fifty-five hips were in patients
with normal function scores, and two were in
patients who reported mild dysfunction. Fifty hips had no
pain, five had slight pain, one had mild pain, and one
had moderate pain. Three hips had a failure of
resurfacing and required revision. Two failures
were secondary to femoral neck fractures, and one
was the result of debonding of the surface coating of the
acetabular component.
Conclusions: The early results associated with a
new generation of hip resurfacing devices are
promising. The anterolateral approach affords the
surgeon excellent exposure with the advantage of
increased hip stability and potentially improved vascular
supply of the femoral head as compared with the
posterior approach.
