Abstract
We used roentgen stereophotogrammetric analysis to follow 33 C-stem femoral components for two years after primary total hip arthroplasty. All components migrated distally and posteriorly within the cement mantle. The mean distal migration was 1.35 mm (SD 0.62) at two years and the mean posterior migration was 1.35 mm (SD 0.69) at two years. All the femoral components rotated into retroversion with a mean rotation at two years of 1.9° (SD 1.1). For all other directions, the prosthesis was stable up to two years. Compared with other tapered prostheses, the distal migration of the C-stem is the same, but posterior rotation and posterior migration are greater.
