About

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.

Enrollment: 200 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Total hip arthroplasty

Exclusion criteria

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

200 participants in 2 patient groups

Control

No Intervention group

Description:

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

Radlink Surgical Positioning System

Experimental group

Description:

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.

Treatment:

Other: Radlink Surgical Positioning Software
