Abstract
The purpose of this study was to examine the correlation between the implanted cup's outer diameter and the actual femoral head diameter removed during surgery. Seventy-five patients with primary total hip arthroplasty were evaluated. The difference between the implanted cup diameter and the femoral head diameter was calculated for each patient. The mean±SD actual femoral head diameter that was removed and measured during surgery was 48.5±3.7 mm. The mean±SD cementless implanted cup outer diameter was 51.8±3.5 mm. A high correlation was found between the implanted cup diameter and the actual femoral head diameter (r=0.923). A cut-off point of 4mm of the measured femoral head diameter should be considered as an additional monitoring indicator.
