A bone coupling device is configured for joining a first bone piece to a second bone piece which includes a first component having an inner surface bounding a first cavity and a first stem portion for insertion into the first bone piece. A second component includes a second stem portion for insertion into the second bone piece and an axially extending connector extending from the second stem portion and configured to be inserted into the first cavity. The connector has an outer surface which is complementarily shaped relative to an inner surface to inhibit rotation relative to each other when the connector is received in the cavity to engage the first component and the second component.

Bone coupling device and method

The present disclosure provides staples, and corresponding staple guides, for applying a compressive force between biological elements. The staples may include a bridge portion and a pair of tines extending from the bridge portion configured for implantation into biological elements. The tines may be spaced a first distance in a first state of the bridge portion. The bridge portion may be elastically deformable into a second state with the pair of tines spaced a second distance that is greater than the first distance and the tines pre-loaded to apply a compressive force therebetween. The guides may include a staple engagement portion operable to maintain the biased state of the staple, and/or a drill guide portion operable to facilitate the formation of apertures spaced the second distance in the biological elements.

Staples and staple delivery and drill guides

The present disclosure provides devices, systems and methods of bone fixation. The disclosed devices, systems and methods facilitate secure fixation of first and second bone segments, such as to promote fusion thereof. The devices may include at least one bone engagement projection extending from an engagement surface of a plate portion for implantation into the first bone segment. A portion of the plate portion spaced from the at least one bone engagement projection may include at least one bone fixation aperture. The least one bone fixation aperture may allow for a one bone engagement projection to be inserted therethrough and into the second bone segment to affix the plate portion to the second bone segment. In some embodiments, the at least one bone fixation aperture may be a compression slot.

Bone fixation devices and methods

Bone plate systems, resection guides, implants, and methods are disclosed. A bone plate system may include a plate including a plurality of openings and a resection guide. A plate may include a body with a first end and a second end, at least two openings in the body, a first opening positioned in the first end and a second opening positioned in the second end, and an alignment marking disposed on a surface of the body. A guide may include a body with a first end and a second end, at least one first opening in the first end of the body, and at least one second opening in the second end of the body. Surgical methods for using the bone plate system, resection guides, and implants are also disclosed.

Proximal bunion resection guides and plates and methods of use

A reversible bone coupling device including a first component having a first elongated stem portion for insertion from a first end longitudinally into a surface of a first bone piece, and a second component having a second elongated stem portion for insertion from a second end longitudinally into a surface of a second bone piece, and a connector extending from a second top for coupling with the first component and reversibly locking therein.

Reversible bone coupling device and method

Bone fixation devices and plates are disclosed. The bone fixation device includes a first portion, a second portion, and a third portion. The first portion includes at least one opening. The second portion includes at least one second opening. The third portion is positioned between the first portion and the second portion and is configured to guide the cutting of a bone. The bone fixation plate includes a first plate portion, a second plate portion, and a third plate portion. The first plate portion includes at least one screw hole for receiving a first bone screw. The second plate portion includes at least one slot for receiving a second bone screw. The third plate portion is positioned adjacent to the first and second plate portions and is configured to guide bone cutting A method of altering a bone using the bone fixation devices and plates is also disclosed.

Bone shortening device and method

Provided is a bone joining device suitable for joining a first bone piece to a second bone piece. Also provided is a method of joining a first bone piece with a second bone piece in a living mammal. The method comprises inserting the above bone joining device between the first bone piece and the second bone piece.

Bone joining apparatus and method

Bone fixation implant

Resection guides, implants and methods are disclosed. A guide may include a plate with a first end opposite a second end and a medial portion extending therebetween. The guide may also include at least one opening in the first end of the plate. The guide may further include at least one hole positioned along a longitudinal axis of the plate near the at least one opening. Surgical methods for using the guide for bone and joint fusions is also disclosed.

Resection guides, implants and methods

A dynamic bone plate and method of bone compression are disclosed. The dynamic bone plate comprises a first bone plate component including at least one hole for receiving screws for attachment to a first bone segment and a male component and a second bone plate component including at least one hole for receiving screws for attachment to a second bone segment and a female component for mating with the male component. The male component is adjustable after mating with the female component to adjust a position of the first bone plate component with respect to the second bone plate component and the male component is locked into place with respect to the female component by at least one screw inserted through the at least one hole of the second bone plate component causing compression between the first and second bone segments to form a corrective construct.
