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.
