Fig. 5From: Combined and hybrid marker models for radiostereometry assessment of polyethylene liner motion in dual mobility hip prosthesis: a proof-of-concept studyExample of anatomic dual mobility cup with a combined marker configuration model. The y-axis is shown for the femoral neck (blue), the cup (red) and the liner (green). ∠A indicates the liner/neck angle. The red circles indicate the detected marker projections in the image, as well as the centre of the femoral headBack to article page
