Abstract: A T-shaped gauge and acetabular cup navigation system and acetabular cup aligning method using the T-shaped gauge, which can measure anantomical landmarks of the pelvis at the same time, calculate an anterior pelvic plane from the measured value, calculate a transformed anterior pelvic plane by converting the anterior pelvic plane in comparison with a pelvic reference frame, and set a direction vector of an acetabular cup on the transformed anterior pelvic plane, thereby exactly inserting the acetabular cup into the acetabulum without regard to movement of the pelvis.

Abstract: A goniometer for measuring artificial acetabular cup angles having the function of measuring an inclination angle and anteversion angle and a method for measuring the artificial acetabular cup angle using the same are disclosed. This goniometer measures the inclination angle or anteversion angle by using the first angle measuring unit, and then measures the inclination angle or anteversion angle by using the second angle measuring unit. Accordingly, it becomes possible to obtain precise operation angles of the acetabular cup easily and quickly, so it is possible to perform the artificial hip joint operation more precisely and quickly.

Abstract: Disclosed herein is a femoral broaching apparatus for use in preparing a femoral cavity for implantation of a prosthetic joint in surgical orthopedic artificial hip joint replacement arthroplasty procedures. The apparatus comprises a fixing guide unit fixed in the femoral cavity by an interference fit, a cavity preparing broach coupled to the fixing guide unit in a longitudinally movable manner, and a vibration-generating unit coupled to the cavity preparing broach for allowing the cavity preparing broach to perform the preparing of the femoral cavity under operation of the fixing guide unit. According to the present invention, a femoral cavity having an intended accurate shape can be easily prepared using mechanical vibration rather than a manual operation, thereby ensuring operational convenience.

Abstract: An artificial joint apparatus used as an artificial joint inserted into a bone is provided. The artificial joint apparatus includes: a body having a stem having a shape substantially corresponding to a space within the bone, into which the stem is inserted, and a head formed integrally with the stem; and a jacket made of a plastic material and surrounding an outer surface of the stem of the body. The jacket is constructed with an outer layer containing a bone-friendly material and an inner layer mainly made of a plastic material. Since the plastic jacket of an artificial joint apparatus has a bone-friendly material, it is possible to promote a growth of a bone contacted thereto. In addition, the bone is grown into a space where the bone-friendly material is dissolved, so that the jacket and the bone can be securely adhered. Since the bone-friendly material also exists in an inner portion of the jacket it is possible to continuously accelerate a bone in-growth.
