All patients were followed clinically prospectively
using the Harris Hip Score (HSS) and
radiographs were evaluated at each follow-up
visit. Patients were seen at six weeks, three
months, six months, one year and yearly
thereafter. None of the patients were lost
to follow-up.
There were fi ve failures early in the clinical
experience that required revision to a
total hip replacement. Only one acetabular
component loosened early in a patient with
signifi cant osteoarthritis secondary to developmental
dysplasia. There were three neck
fractures and one femoral loosening. All were
seen during the fi rst eighteen months of the
study in the initial thirty hips. There have
been no failures in the last thirty-three hips.
The average HHS improved from 51 (30-70)
to 99 (85-100) in the non-revised patients.
The only complication in addition to the failures
was heterotopic ossifi cation (Grade II
or III) in four hips. Radiographic lucent lines
