Abstract
A prosthetic hip joint is disclosed. The prosthetic hip joint includes a femoral component, which further includes a femoral head with a femoral head cavity and an acetabular component. The acetabular component includes an acetabular cup and an acetabular cup insert. The acetabular cup insert and the acetabular cup each has a through hole, where the through holes overlap a location of a native femoral head ligament.
Claims20
A prosthetic hip joint comprising:
- a femoral component including a femoral head with a femoral head cavity;
- and
- an acetabular component including an acetabular cup and an acetabular cup insert, the acetabular cup insert and the acetabular cup each having a through hole, where the through holes overlap a location of a native femoral head ligament.
A method of mounting an acetabular component to a patient, the method comprising:
- positioning and aligning an acetabular jig with respect to an acetabulum, where the acetabular jig includes a bowl-shaped wall having a through hole accommodating throughput of a portion of a femoral head ligament attached to the acetabulum;
- drilling reference holes proximate the acetabulum using the acetabular jig as a guide;
- and
- inserting a pin into each reference hole;
- wherein the positioning and aligning step includes inserting the portion of the femoral head ligament attached to the acetabulum through the through hole of the acetabular jig.
A method of implanting at least one orthopedic hip joint component, the method comprising:
- implanting and mounting at least one of an acetabular component to a native acetabulum and a femoral component to a native femur;
- and
- maintaining a connection between a native femoral head ligament and at least one of the native acetabulum and the native femur.
