An intramedullary nail implant for positioning in a bone having a head and a shaft defining an intramedullary canal. The implant includes a distal portion having a shaft extending along a central axis and configured for positioning within the intramedullary canal. A proximal portion extends proximally from the distal portion. The proximal portion defines a contact surface which extends at least in part medially of the central axis such that it is configured to extend within a medial portion of the bone head. A method of implanting the nail is also provided.

A wrist implant comprising a body section wherein the body section is elongated, wherein the body section has a first end and a distal end along the longitudinal extension of the body section with an elongated opening positioned adjacent to the first end in the body section, at least one wing section coupled to the body section and extending substantially transverse to the elongated extension of the body section, at least one opening in said elongated extension, and at least one opening positioned in the distal end of the body section.

Devices, systems, and methods for bone stabilization, especially proximal humeral stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion. The stabilization system may include an intramedullary nail having an upper portion and a lower portion extending from the upper portion, the upper portion and the lower portion including a plurality of holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and/or one or more of the plurality of holes in the intramedullary nail and into the bone. The plate and nail may each be used alone or in combination together to stabilize a fracture in a long bone, such as a humerus.

Devices, systems, and methods of bone stabilization. The bone stabilization system includes a mesh body. The mesh body includes a plurality of rings, with each of the rings defining a screw hole. Bridge portions extend between and interconnect the rings. The bridge portions have a reduced thickness compared to the rings. An elongate body may also extend from the mesh body. The elongate body defines at least one screw hole.

A fastener, for example a bone screw, is sized to pass through a hole of an implant, for example a bone plate, the fastener having a shaft or anchor portion engageable with body tissue, and a head portion. A locking cap secures to the bone plate and covers the head to block the head and inhibit screw back out. Alternatively, or additionally, a locking disc located in the plate hole resiliently deflects downward to allow screw insertion, but is blocked to limit or prevent upward deflection so that screw back out is inhibited.

The invention concerns a bone plate system comprising: a bone fastening element comprising a shaft with a first thread with a first lead length, the fastening element further comprising a head with a second thread on its outer surface, the second thread having a second lead length, the outer surface having a first hardness; and a bone plate with a second hardness which is smaller than the first hardness, the bone plate comprising a non-threaded through hole in a non-assembled state for receiving the bone fastening element, the hole comprising a first hole portion with a first three-dimensional shape and a second hole portion with a second, different three-dimensional shape. The first lead length substantially equals the second lead length, and the second thread is arranged to irreversible deform the wall of the hole to form a female thread on the wall.

An assembly used in osteosynthesis comprising a delivery instrument in combination with an implant wherein the delivery instrument releasably holds the implant in a first configuration prior to attachment of the implant to bone. The delivery instrument allows the implant to be affixed to bone before the implant is released from the instrument. And the instrument may comprise guide means for drills, depth gauges, screws, pins, pegs, blades and or drivers which are used or implanted when the implant is releasably attached to the instrument. After the implant is affixed to bone and released from the delivery instrument, the implant assumes at least a second configuration which provides compression and or distraction and or control of spatial orientation.

A suture threader configured to thread sutures through suture holes in a bone plate, including: a base; a plurality of hooks attached to the base, wherein the plurality of hooks are arranged at positions on the base corresponding the suture holes on the bone plate.

Disclosed are orthopedic implant kits. One disclosed kit comprises an implant having a joint head portion, the joint head portion having a generally convex distal surface and generally concave proximal surface, the implant comprising a post portion protruding proximally from the proximal surface, the post portion having a dorsal surface and a ventral surface (which is a plantar surface in the case of a metatarsal bone) and including a first threaded aperture extending therebetween, and a bone screw. The bone screw has a threaded shaft complementary to the threaded surface of the post portion and preferably is configured to provide bicortical fixation of the implant.

An embodiment includes a bone fixation system comprising: a plate; and a tool; wherein: (a) the plate includes a hole to receive a bone anchor, (b) the hole includes a shelf, (c) the shelf includes a number of recesses; and (d) the hole is unthreaded and includes no resilient parts; wherein: (a) a distal end of the tool includes one or more lobes, (b) a number of lobes is no greater than the number of recesses, (c) each of the one or more lobes is configured to mate with one of the recesses. Other embodiments are described herein.
