A bone plate for treating periprosthetic fractures includes a head portion to be positioned along a greater trochanter of a bone. The head portion includes pairs of bone fixation element receiving openings extending therethrough from a first surface of the plate which, when the plate is in an operative position, faces away from the bone, and a second surface which, when the plate is in the operative position, faces toward the bone. A pair of cable holes extend through the head portion from a first longitudinal side connecting the first and second surfaces to a second longitudinal side connecting the first and second surfaces. The head portion includes a pair of hooks for engaging a superior ridge of the greater trochanter. The plate also includes a shaft portion extending distally from the head portion to extend along a portion of the bone distal of the greater trochanter.

The apparatus, systems and methods disclosed herein generally relate to the surgical repair or alteration of bone. More particularly, certain of the disclosed apparatus, systems and methods of the present disclosure relate to the use of a directionally-reinforced composite material to emulate anisotropic structural characteristics of an original anatomic trabecular structure. The directionally-reinforced composite material may generally include a scaffold set in a composite matrix, wherein the scaffold determines the anisotropic structural characteristics of the materials. In some of the embodiments, a scaffold may include at least a first plurality of struts which are generally aligned in a first direction and a second plurality of struts aligned in a second direction.

Photodynamic devices for replacement of an articular head of a bone are provided. In an embodiment, a photodynamic device includes a photodynamic support member and an articular member attachable, either fixedly or removably, to the photodynamic support member and having a bearing surface. In an embodiment, the articular member includes a recess designed to receive the photodynamic support member. In an embodiment, the photodynamic support member includes an opening into which a shaft of the articular member can be inserted to attach the articular member to the photodynamic support member.

An orthopaedic fixation assembly for prosthetic biologic attachment. The orthopaedic fixation assembly may include a main body with a longitudinally-extending stem having a proximal end, a distal end, and a cavity body. An anchor plug may be configured to be received within the stem cavity, and securable thereto via complementary mating surfaces. A spindle structure may be fixedly attached to the proximal end of the longitudinally-extending stem and protrude outwardly therefrom such that a portion of the structure extends externally beyond the resected cavity of the bone that may prevent rotational motion of the spindle. The spindle structure may have at least one compliant biasing member configured to apply a compressive force to the surrounding bone. A porous coating may be at the juncture between stem and spindle structure, on the spindle, and the splines and anti-rotation chocks, improving the initial stability of the implant and facilitating long-term bone ingrowth.

Intramedullary nails, aiming guide assemblies, and methods. The aiming guide assembly can include an aiming guide having an elongate proximal handle portion. A generally arcuate distal implant alignment tip connector portion is connected to the proximal handle portion and has a distal implant alignment tip extending along a tip axis parallel to a longitudinal axis of the proximal handle portion. A recon module may be releasably attached to a proximal end of the proximal handle portion. An oblique module may be releasably attached to the distal implant alignment tip portion.

A femoral nail includes a proximal section, a distal section remote from the proximal section, and an intermediate section disposed between the proximal section and distal section and having first and second curved portions. The first curved portion is positioned closer to the proximal section than the second curved portion. The second curved portion is curved in a first plane, and the first curved portion is curved in the first plane and a second and third plane.

The present disclosure relates to a rotation prevention member of a leg screw for fixing a bone that is configured to prevent rotation of a leg crew that is coupled to a nail in a medullary cavity such as a femur and fixes a fracture portion. The rotation prevention member of a leg screw for fixing a bone, in which a femoral nail is fitted in an end of a femoral marrow, a leg screw combined with a cap is laterally inserted in a transverse hole formed at an angle with respect to a longitudinal axis of the nail, and the leg screw is fixed to be longitudinally movable without rotating in the transverse hole, includes: pin guide grooves formed symmetric to each other in a longitudinal direction of the leg screw; a superelastic member inserted in the pin guide grooves; and a cap thread-fastened to a rear surface of the leg screw to prevent separation of the superelastic member in order to prevent rotation between a threaded portion of the leg screw and a bone due to rotation after a fracture part is occupied.
