A device provides a variety of fracture fixation options should a fracture occur after total hip arthroplasty or total knee arthroplasty, and provides associated methods and apparatus for application of provided fixation. The ability to pre-engineer fracture fixation contingent solutions into femoral or tibial components provides for a distinct clinical advantage in the planning and execution for periprosthetic fracture fixation. Said methods and apparatus include targeting devices which allow for intimate association of fixed angle locking screws in pre-drilled holes in an existing prosthetic, femoral nail, or other components including additional fixation components. Such apparatus and methods further include the use of alignment devices and other components to allow for ease of repair of fractures utilizing the pre-engineered solutions.

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.

A hip joint prosthesis is formed of a coil spring having a middle section bounded by first and second opposite ends, with one of the two ends configured as a femoral fixing end and the other of the two ends configured as an acetabular fixing end. A central axis of the coil spring extends between the two opposite ends, providing a freely movable, flexible central coil linking the two ends.

A modular femoral prosthesis for use during performance of a hip revision procedure includes a proximal body component, a distal stem component, and a locking bolt. Surgical instruments and methods for use in implanting such a modular femoral prosthesis are disclosed.

The invention discloses a bionic artificial hip joint. The artificial hip joint includes a femoral stem located above corpus femoris, and a convex force-bearing part is provided on the femoral stem. The force-bearing part abuts against the inner side of the cortex on greater trochanter and bears a part of the longitudinal stress; its hollow design is convenient for bone grafting, so that the prosthesis and the greater trochanter can be integrated. Replacement surgery can preserve the hard cortex on the greater trochanter, providing another focus point for the femoral stem and further improving the stability of the connection between the bionic artificial hip joint and corpus femoris.

An apparatus, system, and method may be used to replace a natural or artificial articular surface of a joint, and to repair a bone that is associated with the joint. In some embodiments, the apparatus, system, and method may include a joint replacement prosthesis with a prosthetic articular surface, a support structure securable to the bone, and a first attachment interface. The system may also include a bone plate with a bone engagement surface securable to the bone on either side of a fracture formed in the bone, or a damaged area of the bone. The bone plate may include a second attachment interface that is attachable to the first attachment interface of the joint replacement prosthesis in order to couple the bone plate to the joint replacement prosthesis.

A hip implant having two distinct bodies, a neck body and a bone fixation body. The neck body is formed from a solid metal and has an interface for connecting to a femoral ball. The bone fixation body has an elongated shape and is formed as a porous structure that is inserted into an intramedullary canal of a patient.

An intramedullary stem prosthesis includes a trunnion tapered in a first direction toward a proximal end of the intramedullary stem, and a conical shaft interfacing with the trunnion at a modular taper junction. The conical shaft is tapered in a second direction toward a distal end of the second component and has a proximal portion, a distal portion, and flutes positioned about a longitudinal axis of the conical shaft and extending along an entire length of the conical shaft and terminating at the modular taper junction such that the flutes intersect the modular taper junction. The proximal portion defines a first taper angle, the distal portion defines a second taper angle greater than the first taper angle, and the flutes define a major diameter of the conical shaft. The major diameter tapers at a major diameter taper angle that is constant along the entire length of the conical shaft.
