Study of Total Hip Arthroplasty Using Radlink Surgical Positioning Software
- Conditions
- Total Hip Replacement
- Interventions
- Other: Radlink Surgical Positioning Software
- 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.

Group Intervention Description Radlink Surgical Positioning System Radlink Surgical Positioning Software 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.
- Primary Outcome Measures
Name Time Method Radiographic cup abduction angle 4 month postoperative Angle of acetabular component in coronal plane measured on x-ray
Radiographic cup anteversion angle 4 month postoperative Angle of acetabular component in sagittal plane measured on x-ray
- Secondary Outcome Measures
Name Time Method Variance of cup angles measured on x-ray 4 month postoperative Statistical homogeneity of angles and how spread out the data is.
