HIP
The HIP calculation assists in assessing the development of the infant hip. In this calculation, three
straight lines are superimposed on the image and aligned with the anatomical features. The two
angles are calculated and displayed.
The three lines are:
The baseline (BL), connecting the osseous acetabular convexity to the point where the joint
capsule and the perichondrium unite with the ilium.
The roof line (RL), connecting the lower edge of the ilium to the osseous acetabular convexity.
The inclination line (IL), connecting the osseous acetabular convexity to the labrum acetabular.
The angles are:
α: the angle between BL and RL.
β: the angle between BL and IL
Dislocation type can be determined through Graf method, as described in the following table.
