A bone plate includes first and second ends opposed along a longitudinal axis oriented along a longitudinal direction, first and second sides opposed along a lateral direction, and a bone-facing surface and an outer surface opposed along a transverse direction. The plate defines a first hole and a second hole arrangement extending from the outer to the bone-facing surface. The second hole arrangement is distal of the first hole, which is configured to receive a first fixation member, and the second hole arrangement is configured to receive at least one second fixation member for affixing with underlying bone. The plate is pivotable along an angulation range about the first hole. The second hole arrangement laterally crosses the longitudinal axis, defines the angulation range, and allows the at least one second fixation member to substantially secure the plate to the underlying bone at any angulation within the angulation range.

Bone plates, and related systems and methods

A humeral nail can include a nail longitudinal axis extending from a proximal portion to a distal portion, a first proximal through bore defining a first screw trajectory, a second proximal through bore defining a second screw trajectory, a third proximal through bore defining a third screw trajectory, a descending through bore defining a descending screw trajectory, and a calcar through bore defining a calcar screw trajectory. The first, second and third screw trajectories extend transverse to the nail longitudinal axis, the descending screw trajectory extends anterior to posterior and proximal to distal, and the calcar screw trajectory extends distal to proximal, anterior to posterior, and lateral to medial. In some examples, the calcar through bore defines at least two calcar screw trajectories.

A bone plate for treating periprosthetic fractures includes a head portion sized and shaped so that, in an operative position, a proximal end thereof aligns with a vastus ridge of a greater trochanter of a femur. The plate also includes a shaft portion extending distally from the head portion. The shaft portion includes offset holes to receive bone fixation elements therethrough. Each of the offset holes includes a first hole positioned on a first side of a longitudinal axis of the plate and a second hole positioned on a second side of the longitudinal axis opposite the first side so that bone fixation elements inserted therethrough extend anterior and posterior of a prosthetic received within the femur. The first and second holes are staggered relative to one another along a length of the shaft portion and extending beyond longitudinal edges of the shaft portion.

Proximal femur plate system

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.

Proximal femur hook plate

Various intramedullary implants, instruments, and methods are disclosed herein. In an example, a compression instrument is used to provide internal compression of bones adjoining a joint or bones spanning a fracture to cause compression of the joint or fracture.

Joint compression instrumentation and methods

Various modular implants and modular implant systems are disclosed herein, as are methods of implanting the same. The modular implant systems can include modular implants that are stacked on each other to define a modular implant system, which in an example can be used to replace or augment a void in bone. The modular implants can interact with an intramedullary implant to, for instance, assist with a fusion procedure.

Implants for bridging osseous defects

A plate for treating a bone includes a plate body extending along a longitudinal axis from a first end to a second end and being sized, shaped and contoured to be positioned along a desired surface of a bone. The plate also includes a slotted opening extending through the plate body and defined by a first portion sized and shaped to permit a head portion of a bone fixation element fixed to the bone to be passed therethrough and a second elongated portion extending along the longitudinal axis from the first portion in communication with the first portion, the second portion sized to prevent the head portion of the bone fixation element from being passed therethrough so that, when the head portion of the bone fixation element is received through the first portion, the plate is slidable relative thereto such that the second portion engages the head portion of the bone fixation element.

A medical implant apparatus for total elbow arthroplasty is provided. The apparatus includes: a first rod member comprising a first nut, an eye hook, a first end, and a second end, wherein the first nut is disposed at the first end and the eye hook is disposed at the second end; a second rod member rotatably coupled to the first rod member, the second rod member comprising a first linear portion, a second linear portion, and an arcuate portion disposed between the first linear portion and the second linear portion, the arcuate portion being configured to form a predetermined angle between the first rod member and the second rod member; a positioning nut coupled to the first linear portion of the second rod member; and an aperture disposed in the eye hook.

Total elbow arthroplasty apparatus and method

An encasement for coating a bone plate with a substrate includes a sidewall structure having an upper edge and a cover disposed on the upper edge of the sidewall structure. The encasement includes a base from which the sidewall structure rises such that the sidewall structure, the cover and the base combine to create an open interior space of the encasement. An aperture in the sidewall structure provides access to the open interior space of the encasement and a plurality of cover protrusions extend from the cover into the open interior space. The encasement further includes a plurality of base protrusions extending from the base directly opposing the plurality of cover protrusions. A combined height of an individual cover protrusion and an opposing base protrusion is less than or equal to a height of the sidewall structure.

Device for coating bone plate

An intramedullary nail comprises longitudinal channel, a first transverse passage and a second transverse passage. A lag screw extends through the first transverse passage of the intramedullary nail. An anti-rotation shaft extends through the second transverse passage of the intramedullary nail. A cannulated lag screw lock is positioned in the intramedullary shaft and engages the lag screw. The anti-rotation shaft extends through a cross channel in the lag screw lock. A second shaft lock is positioned in the intramedullary nail with the second shaft lock engaging the anti-rotation shaft. In at least one embodiment, the lag screw lock includes a substantially cylindrical body portion rotatably connected to a threaded head portion. In at least one embodiment, the second shaft lock is provided as an end cap including a threaded upper portion and a lower post portion that extends into the lag screw lock.

An instrument system is provided for positioning an internal fixation prosthesis and guiding a cannulated bone drill during a surgical, radioscopic procedure for the repair of a fractured bone of a patient. The instrument system includes a target wire, a handle formed from a radio translucent material having a target hole for guided passage of the target wire along a target axis. The target axis coincides with the intersection of a first plane and a second plane orthogonal to the first plane. The instrument system also includes a nose component attached to an end of the handle and removably connectable to the prosthesis. The nose component includes an alignment sight formed from a radio-opaque material. When the prosthesis is connected to the nose component and the target wire is positioned through the target hole along the target axis, the image of the guide wire may be radioscopically viewed along a first line of sight contained in the first plane to bisect the image of the alignment device, thereby providing a first visual reference to the user for directing the first guide wire into the desired portion of the bone while holding the prosthesis in a desired position relative to the bone.
