title: A comparison of cementless acetabular components of the same design: spiked versus supplemental screws.
abstract: The purpose of this report was to compare the results of a series of otherwise-identical, cementless acetabular components with screws to a group with spikes in primary total hip arthroplasty. Between April 1993 and August 1997, 339 primary total hip arthroplasties were performed using a cementless acetabular component in 312 patients. There were 227 acetabular components with screws and 112 with spikes only. Radiographic evaluation was performed at a mean of 4.8 years' postarthroplasty (range, 2-8.6 years). No significant difference was identified between the 2 groups in regard to radiographic or clinical parameters.
