Clinical Trial Summary

The purpose of this study is to compare the performance of 4 designs of the DePuy Ultima LX hip stem in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to one of the 4 designs of the DePuy Ultima LX hip stem and will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments.

Outcome

Type Measure Description Time frame Safety issue
Primary Stem movement measured radiographically at 2 years Stem movement was measured radiographically by comparing baseline stem position with the stem position 2 years after surgery. If migration was observed to be 5 or more mm, it was considered clinically significant migration. 2yrs post-surgery No
Secondary Comparisons of Visual Analog Pain (VAS), 36-Item Short Form Health Survey (SF-36), Satisfaction, Limb Length and stem movement measured radiographically at 5 years. The following outcome measures were used; VAS Pain score, SF36 Patient reported outcome, Satisfaction, Limb Length physical examination, and stem movement measured radiographically. 5yrs post-surgery No
