Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study aims to describe bone apposition and fixation of the Trident and Trident II Tritatnium acetabular system in patients 1 year status post total hip replacement. We will be studying this by comparing magnetic resonance imaging (MRI)s taken 1 year s/p total hip replacement with a Trident II cup with MRI's taken of patients with the Trident Cup who had MRIs done at 1 year post-op.

Intervention Model

PARALLEL

1 control group who have had been implanted with a Trident cup and have already had MRIs taken at their one year post-operative visit. This group's MRI's will be compared with MRI's from Tridend II patients who have had MRI's at 1 year post-operative visit.
