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. In some embodiments, the proximal end may further include a cross-locking feature, which includes a second bone anchor that interlocks with a first bone anchor, for example, for enhanced bone purchase and bony fixation.

Claims13

Dependent claims

An implant comprising:

an intramedullary nail having:
an elongate body extending from a proximal portion to a distal portion, at least a portion of the elongate body extending along a first axis;
a first aperture formed in the proximal portion, the first aperture defining a second axis transverse to the first axis;
and
a second aperture formed in the proximal portion, the second aperture being spaced apart from the first aperture and located proximally to the first aperture, the second aperture defining a third axis transverse to the first axis, the third axis intersecting with the second axis at a point spaced apart from the body and an angle between the third axis and the first axis is 70-90 degrees;
an anchor configured to extend through the first aperture of the intramedullary nail, the anchor comprising a first side portion, a second side portion opposite the first side portion, and an elongate opening extending through the anchor from the first side portion to the second side portion;
and
a fastener configured to extend through the second aperture and the elongate opening of the anchor beyond the second side portion of the anchor, wherein an angle between a distal tip of the fastener and a distal tip of the anchor is 25-65 degrees, and the elongate opening in the anchor has a length greater than a diameter of the fastener and is sized to allow translation of the anchor after the fastener has been passed through the elongate opening.
