简要总结
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.

研究组 & 干预措施
Control
Intraoperative fluoroscopy of the hip is used to visually estimate the acetabular cup angle and make any necessary adjustments.
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.
干预措施: Radlink Surgical Positioning Software (Other)
