Study of Total Hip Arthroplasty Using Radlink Surgical Positioning Software

Not Applicable

Completed

• Conditions: Total Hip Replacement

• Registration Number: NCT02536573
• Lead Sponsor: Anderson Orthopaedic Research Institute

Brief Summary

This is a prospective, randomized study of total hip arthroplasty with and without the use of Radlink surgical positioning software. The investigators are interested in discovering whether the use of the Radlink software will provide more accurate acetabular cup position when compared with surgeon estimates based on visual inspection of fluoroscopic images.
