Total Hip Arthroplasty: Fluoroscopy vs Freehand

The aim of the study is to compare total hip arthroplasty intervention executed with or without the use of intraoperative fluoroscopy in terms of positioning of the hip prosthesis. The comparison will be made on post-operative follow-up X-ray performed as per clinical practice, in order to verify if intraoperative fluoroscopy provides better prosthesis components positioning or not.

Treatment and study plan

Intraoperative fluoroscopy

Device

Fluoroscopy is a medical procedure that makes a real-time video of the movements inside a part of the body by passing x-rays through the body over a period of time.

Primary outcomes

  1. Acetabular component anteversion

    Time frame: 2 months post-operative

    Acetabular component anteversion will be measured on post-operative control antero-posterior pelvis view X-ray performed as per clinical practice using the PACS software according to the method described by Lewinnek et al. This method is based on the following equation to measure radiographic anteversion β.

    β = arcsin(S/L)

    Where S is the length of the short axis and L is the length of long axis of the ellipse. The ellipse is formed by the outer ring of the acetabulum component on the anteroposterior pelvis view X-ray.
