CERAMIC MONOBLOC FEMORAL COMPONENT, KIT AND SYSTEM COMPRISING THE SAME, AND METHOD OF MANUFACTURE AND USE THEREOF
A ceramic monobloc femoral component (10) is provided for a total hip replacement prosthesis. The ceramic monobloc femoral component (10) has a ceramic femoral stem (14) and a ceramic head (12) which defines a part-spherical articular surface receivable by an acetabular cup (56). The ceramic femoral stem (14) and the ceramic head (12) are integrally formed as one-piece.
Surgical component, kit and method
A surgical component, a kit including the surgical component, and a surgical method. The surgical component includes a body portion. The surgical component also includes an elongate stem for inserting into an intramedullary canal of a patient. The elongate stem extends distally from the body portion. The elongate stem has a longitudinal axis; a proximal end; a distal end; and a plurality of splines located on an outer surface of the stem. The splines are circumferentially arranged around the stem. At least some of the splines are tapered such that each tapered spline is narrower at a distal part of that spline than at a part of that spline that is proximal with respect to the distal part. The surgical component further includes an elongate neck portion extending from the body portion at a non-zero angle with respect to the longitudinal axis of the stem.
Additive manufactured femoral components
Described is a femoral component of a prosthetic hip implant. The femoral component can include: a neck portion; and a stem portion including a proximal end and a distal end. The neck portion extends from the proximal end, and the stem portion comprises a first solid portion and at least one additional portion including at least one of a hollow portion, a porous portion, and a second solid portion comprised of a different solid material from a solid material of the first solid portion. The first solid portion and the at least one additional portion are in a predetermined configuration. The femoral component comprises a unitary component that is formed by additive manufacturing of the femoral component from a 3D model of the femoral component.

Hip or shoulder prosthesis and placement instruments
A hip/shoulder prosthesis includes: a head component; a metaphyseal component; a diaphyseal nail, and a locking device. The head component includes: a front face and rear face; with a bore, and first and second shaped recesses in the rear face. The metaphyseal component includes: a central transverse aperture at an angle to the metaphyseal component's axis; a first end configured for threaded engagement within the bore of the head component; and a longitudinal hole that begins at the second end, transects the transverse aperture and reaches the first end, to receive the locking device. The diaphyseal nail is inserted in the femoral or humeral canal, and includes: fastening apertures that receive corresponding screws for fastening the diaphyseal nail to the femur or humerus; a portion configured to he received within, and engage, the transverse aperture of the metaphyseal component, and a transverse hole configured to receive the locking device.
