Component malpositioning during Birmingham hip resurfacing increases the risk for
component wear, metallosis, component loosening, and the likelihood of
dislocation and revision surgery. Computer-assisted navigation can increase the
accuracy to which components are placed, and the utilization of this technology
in Birmingham hip resurfacing is increasing. The present report summarizes the
accuracy of acetabular component positioning in a Birmingham hip resurfacing
case utilizing navigation. Intraoperative C-arm fluoroscopy following the use of
the navigation tool confirmed excellent seating, positioning, and stability of
the acetabular component. In addition, post-operative antero-posterior
radiographs confirmed device accuracy and revealed a stable joint with no
evidence of acetabular loosening or femoral fracture. Computer-assisted
navigation may therefore be an effective tool to improve the accuracy of
component positioning during Birmingham hip resurfacing.
