Abstract

Intramedullary nails, systems, and methods. The intramedullary nail may include a generally elongate body extending from a first, distal end to a second, proximal end. The distal end may include one or more openings configured to receive one or more bone anchors that extend transversely through the distal end intramedullary nail, and thereby configured to secure the distal end of the nail. The proximal end may also include one or more openings configured to receive one or more bone anchors that extend transversely through the proximal end of the intramedullary nail, and thereby configured to secure the proximal end of the nail.

Claims20

Dependent claims

An intramedullary system configured to stabilize bone, the system comprising:

an intramedullary nail having:
a body elongated along a first axis, the body having a distal portion configured to facilitate entry into an intramedullary canal and a proximal portion opposite the distal portion, the body having a curvature in the anteroposterior direction and a bend in the medial-lateral direction, the body having an opening in the proximal portion, the opening having a shoulder and circumferential slot capable of non-threadably connecting to an insertion instrument;
a first aperture formed in the distal portion and transverse to the first axis;
a second aperture formed in the distal portion and transverse to the first axis;
a third aperture formed in the distal portion and transverse to the first axis;
a first elongated aperture formed in the distal portion and transverse to the first axis;
a fourth aperture formed in the distal portion and transverse to the first axis;
a fifth aperture formed in the distal portion and transverse to the first axis;
and
a second elongated aperture formed in the distal portion and transverse to the first axis,
wherein the first aperture, the second aperture, the third aperture and the first elongated aperture are positioned on a first plane,
wherein the fourth aperture, the fifth aperture, and the second elongated aperture are positioned on a second plane,
wherein the first plane and the second planes are perpendicular.
