Abstract
Our aim was to assess the clinical and radiological medium-term outcome of a series of 153 consecutive total hip arthroplasties performed by two surgeons in Christchurch using the ABG hydroxyapatite-coated femoral stem and Duraloc 100-series uncemented acetabulum.
An independent clinical review using interviews and patient notes and radiological review of immediate postoperative and most recent x-rays was carried out.
At six to eleven years with approximately 95% follow-up, there were no stem failures, but two revisions following a fracture from significant trauma. Two cups were revised for loosening and one cup bone grafted for osteolysis. A dislocation occurred in 4.7% of cases requiring two liner exchanges and one cup revision. A low incidence of thigh pain and excellent radiographic results of the stem with high rates of bony ingrowth and no incidence of significant loosening was a feature of this series.
We report excellent results at medium-term follow up for an unceme4nted HA- coated femoral stem.
The abstracts were prepared by Jean-Claude Theis. Correspondence should be addressed to him at Department of Orthopaedic Surgery, Dunedin Hospital, Private Bag 1921, Dunedin, New Zealand.
