In a retrospective study, 138 unselected consecutive uncemented hip arthroplasties
were performed on 133 patients between January 2005 and November 2009
diagnosed with Developmental or Congenital Dysplasia of the Hip using the Wagner
femoral stem. Grades of Dysplasia were from 1 to 3rd as described by Hartofilakides
et al. The mean age of the patients at the time of the operation was 49,4 years (20 to
81). None were lost to follow up, with revision for stem instability as the end point.
Only two femoral components (1.45%) were revised, due to periprosthetic fractures.
In our cohort, there were no cases of aseptic loosening or infection. The operations
were performed by three experienced orthopaedic surgeons through an anterolateral
approach. No prophylaxis was given to prevent heterotopic ossification. All patients
were partially weight-bearing for six weeks post-operatively, and thereafter as
tolerated. In no case was there performed an osteotomy of the acetabulum or of the
femur. The maximum leg length discrepancy which was restored was 6cm. There
were 2 cases of transitory neuropathy of the fibular nerve, both cases resolved by the
time of first year follow-up. This study indicates that the Wagner femoral stem has
reliable good and excellent short-to-mid term results and can be used in cases of
dysplasia of the hip. Disclaimer: The authors did not receive any outside funding or
