A modular femoral internal implant system for use in the treatment of femoral disorders resulting from injury, disease or congenital defect includes at least three interconnectable components: 1) an elongated epiphyseal/metaphyseal implant, 2) an intramedullary rod and 3) an angled side plate having an elongated plate portion adapted to be secured to the outer cortical wall and a hollow sleeve adapted to extend into the femur. The epiphyseal/metaphyseal implant can be connected to either the angled side plate or the intramedullary rod. The system may also include an elongated bone plate connectable to the angled side plate, one or more additional epiphyseal/metaphyseal implants of variable length, an additional angled side plate, a distal buttress plate connectable to the elongated bone plate, and a plurality of bone screws of a universal design. Preferably, many or all of the components of the system are made of an inert, resilient titanium-base alloy.
A bone implant assembly comprising: an elongated bone plate adapted to be secured to a patient\s bone having an upper surface, a lower surface intended to be adjacent the patient\s bone in use and two side surfaces connecting the upper and lower surfaces, with the thickness of the plate being substa
A bone implant assembly comprising: an elongated bone plate adapted to be secured to a patient\s bone having an upper surface, a lower surface intended to be adjacent the patient\s bone in use and two side surfaces connecting the upper and lower surfaces, with the thickness of the plate being substantially constant between the two side surfaces, the width of the upper surface being greater than the width of the lower surface, said side surfaces being tapered inwardly toward one another from said upper surface to said lower surface, with said bone plate being adapted to be secured to the patient\s bone by means of bone fasteners received in apertures in the bone plate, and a surgical implant having an elongated plate portion, having an upper surface and a lower surface, adapted to be secured to the patient\s bone by means of bone fasteners received in apertures in said elongated plate portion, with a cavity being formed in the lower surface of the elongated plate portion at a free end of said plate portion, said cavity extending longitudinally from said free end to a shoulder defining an end of the cavity and said cavity having a transverse cross-section complementary to that of said elongated bone plate so that said elongated bone plate can enter and be removed from said cavity only by relative axial movement between said elongated bone plate and said elongated plate portion, and with at least one of said bone fastener-receiving apertures in said elongated plate portion, which at least one aperture is in communication with said cavity, overlying a bone fastener-receiving aperture in said elongated bone plate when said bone plate is inserted into said cavity and an end of said bone plate abuts said shoulder.
