Abstract

An implant having a unitary body includes an intramedullary portion and an extramedullary portion. The intramedullary portion is sized and structured to be received within an intramedullary canal of a first bone and defines a longitudinal axis. The extramedullary portion includes a surface defining an axis that is disposed at an angle with respect to the longitudinal axis. An aperture defined along the extramedullary portion is sized and configured to receive a fastener therein for coupling the extramedullary portion of the implant to a second bone.

Claims (19)

1 . An implant comprising:

a unitary body including an intramedullary portion and an extramedullary portion including a circular head that is larger than the intramedullary portion, wherein

the intramedullary portion has a single cylindrical section defining a longitudinal axis and including a flat surface extending from the cylindrical section such that the intramedullary portion tapers at a first end,

the circular head of the extramedullary portion includes a flat surface defining an axis, the flat surface being located on an opposite side of the extramedullary portion as a bone-contacting surface, wherein the flat surface is disposed parallel to the bone-contacting surface and extending across the extramedullary portion and along at least a portion of the intramedullary portion, and the axis defined by the surface of the extramedullary portion is oriented at an oblique angle with respect to the longitudinal axis of the intramedullary portion,

the extramedullary portion defines a single aperture formed centrally through the circular head and positioned at an oblique angle with respect to the longitudinal axis defined by the intramedullary portion of the implant further defined by thread segments circumferentially spaced-apart by transverse cuts in the extramedullary portion that defines the aperture, the aperture sized and the intermittent thread segments configured to receive a fastener at an angle of between 0° and 15° relative to a central axis defined by the aperture, and

the bone-contacting surface of the extramedullary portion is configured to abut an external surface of a first bone when the intramedullary portion is oriented within an intramedullary canal of a metatarsal such that the longitudinal axis is substantially parallel to the metatarsal.

2 . The implant of claim 1 , wherein the fastener is one of a locking fastener and a non-locking fastener.

3 . The implant of claim 1 , wherein the first end of the intramedullary portion of the implant includes two flat surfaces such that the implant tapers to a blunt end at the first end.

4 . The implant of claim 1 , wherein the first end of the intramedullary portion of the implant includes two flat surfaces such that the implant tapers to a blade at the first end.

5 . The implant of claim 1 , wherein the extramedullary portion of the implant is enlarged with respect to the intramedullary portion.

6 . The implant of claim 1 , wherein the intramedullary portion of the implant includes one or more surface features disposed thereon for resisting rotation of the implant once implanted.

7 . The implant of claim 1 , wherein

the intramedullary portion is sized and structured to be received within an intramedullary canal of a first bone,

the aperture is sized and configured to couple the extramedullary portion to a second bone, and

the first bone is a first bone fragment formed from a third bone, and the second bone is a second bone fragment formed from the third bone.

8 . The implant of claim 1 , wherein

the intramedullary portion is sized and structured to be received within an intramedullary canal of a first bone,

the aperture is sized and configured to couple the extramedullary portion to a second bone, and

the first bone and the second bone are two adjacent bones of a joint.
