Brief Summary

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

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control

Intraoperative fluoroscopy of the hip is used to visually estimate the acetabular cup angle and make any necessary adjustments.

Group Type NO_INTERVENTION

No interventions assigned to this group

Radlink Surgical Positioning System

Fluoroscopic image of the hip joint is imported into the Radlink Surgical Positioning software. The software calculates a target cup position using bony landmarks, and the surgeon matches the cup to the target.
