Patent ID: 11207195

Abstract:
An apparatus and method for aligning an acetabular cup. The apparatus may include an acetabular cup (150, 10) and/or a protractor (30) and/or a depth gauge tool (90) and may be provided in the form of a surgical kit. Components of the apparatus may allow an angle of rotation of an acetabular cup about an axis (111) of the cup relative to an anatomical feature of a patient to be determined when the acetabular cup implant is placed in the acetabulum of the patient. Components of the apparatus may allow an amount of overhang between a rim (12, 162) of an acetabular cup and an edge of the acetabulum to be determined. The acetabular cup may be an acetabular trial cup (10) or and acetabular cup implant (150). Embodiments of the invention may allow both the angle of rotation about the cup axis and the amount of overhang between the rim and the acetabulum edge to be determined.
