Radlink GPS Provide a Valid Intra-operative Assessment of Acetabular Inclination and Anteversion
Radlinik GPS Provide a Valid Intra-operative Assessment of Acetabular Inclination and Anteversion
研究概览
详细说明
Evaluate the accuracy of Radlink System in determining acetabular cup placement and limb length evaluation during Anterior hip replacement as measured intraoperative with C-Arm visualization and confirmed with digital x-ray at 4-6 weeks postoperatively.
GPS may improve total hip replacement by allowing surgeons to measure the exact position of components placed during surgery and there is a question whether RADLINK helps surgeons place the acetabular cup (the part that goes into the hip bone) component in a precise position. The objective of the study is to determine whether GPS gives surgeons reliable, valid information about the orientation of the cup component. The surgeons need to collect data to help clarify this issue.
