Abstract: A bone fixation plate comprises a main body formed of a first material and a support member formed of a second, different material and attached to the main body. The main body defines a first set of openings and the support member defines a second set of openings aligned with the first set of openings. For each opening of the first set of openings, a main body circumferential surface is disposed adjacent and continuous with a support member circumferential surface of the second set of openings to define an opening circumferential surface that bounds an opening of the first set of openings and an opening of the second set of openings.

Abstract: Intramedullary rods, targeting devices, intramedullary rod systems, intramedullary rod kits, and methods of placing an intramedullary rod in a bone are described. An intramedullary rod comprises a head member having a first end, a second end, and a body extending between the first end of the head member and the second end of the head member. The head member is formed of a first material and defines a circumferential flange and a circumferential shoulder. The circumferential flange extends radially outwardly from the head member and the circumferential shoulder is disposed between the first end of the head member and the circumferential flange. A shaft member extends from the head member and a head extension is partially disposed over the head, member. The head extension is formed of a second material that is different than the first material and has an end contacting the circumferential shoulder of the head member.

Abstract: A bone plate includes a main body defining one or more openings and a cavity. A support member formed of a different material than the material of the main body is disposed in the cavity and defines one or more openings, each of which is coaxial with an opening of the main body. The support member extends into circumferential recesses defined by the main body. Circumferential projections bounding each main body opening are disposed between circumferential projections of the main body and are disposed entirely within the support member. Bone plate systems, methods of treatment, and methods of manufacturing are also described.

Abstract: Various temporary fixation devices, fixation systems and kits, and methods of fixing a bone plate to a bone are described. A temporary fixation device includes a wire member and a retaining member. The wire member has a proximal end, a distal end, a flange disposed between the proximal end and the distal end, a first portion extending from the proximal end to the flange and defining a first outer diameter, and a second portion extending from the distal end toward the flange and defining a second outer diameter and a second portion outer surface. The retaining member defines an inner passageway and can be disposed on the second portion of the wire member such that the retaining member is movable along the second portion of the wire member, from the distal end to the flange. The elongate member comprises a first material and the stopping member comprises a second material that is different from the first material.
