A compression device made of a superelastic material having a peripheral portion with an upper surface, a lower surface, and a central opening extending therethrough is provided. Tips of one or more resilient structures of the compression device project inward of the peripheral portion and form an opening. The one or more resilient structures are configured to exert a biasing force in a direction when deformed in an opposite direction. Also provided is a bone plate assembly comprising a captively retained compression device and a bone plate comprising one or more integrally formed resilient structures.

The present invention provides an orthopedic implant including a base device having a device surface and a fixation material attached to at least one portion of the device surface. The fixation material is configured to provide a minimally sufficient adhesive force to resist natural pull out caused by forces acting on the base device after implantation and bone growth. Also provided is a method of manufacturing an orthopedic implant. A base device with a device surface is provided and a minimally sufficient adhesive force, that can resist natural pull out caused by forces acting on the base device after implantation and bone growth, is determined. A proper amount of fixation material sufficient to provide an adhesive force equal to the minimally sufficient adhesive force is determined and fixation material is applied to the device. When the proper amount of fixation material is applied to the device surface, application is stopped.

A bone plate can be used to fixate one or more bones. In some examples, the bone plate defines an elongated body having a plurality of fixation holes arrayed at different points along the length of the body. For example, the bone plate may have opposed fixation holes separated by a bridge. The bone plate may be bent or shaped along a central longitudinal axis extending through the elongated body and also twisted around the central longitudinal axis. The bending and twisting can position each fixation hole of the elongated body in a different plane in three-dimensional space.

A bone plate kit may be provided for a foot or ankle orthopedic procedure, such as a lapidus procedure. In some examples, the bone plate kit includes a sterile container that holds multiple unicortical bone plate fasteners and one or more bone plates. For example, the kit may contain two bone plates configured to be used together during a tarsal-metatarsal fusion procedure. Each of the two bone plates may be configured to span different regions of a tarsal-metatarsal joint. The unicortical bone plate fasteners can be used to secure the two bone plates to the first metatarsal and medial cuneiform of a patient undergoing a procedure. In some configurations, one of the bone plates is a helical bone plate while the other bone plate may or may not be a helical bone plate.

Methods and systems related to osteosynthesis are discussed herein. A construct for bone plate modularity and augmentation is disclosed. As used herein, the term construct refers to the functional combination of two or more implants, such as bone screws and bone plates. The construct includes a bone plate having a bone-facing surface and an opposite surface, at least one hole through the bone plate from the bone-facing surface to the opposite surface, and a primary threaded element. The primary threaded element extends through the hole, spans between the bone-facing surface and the opposite surface, and has a tip located on a side of the bone plate. The construct also includes a threaded interface separate from the bone plate, located on the side of the bone plate, and locking the primary threaded element in place in the construct.

A radial inclination volar angle restoration plate includes a shank and a window portion. The plate also includes holes for accepting bone fasteners, as well as holes for accepting respective pegs from distal and radial pads. The pads are engageable with the plate via the pegs and can guide an osteotome extending through a window of the window portion to help reduce a bone fracture. The plate, fasteners, pads, and/or osteotome may be included together in a kit.

A device for coaptation of bone parts or bone fragments, comprising an integral plate obtained by moulding whereof one portion (1) is made from a first biocompatible polymer comprising at least one or, preferably, a plurality of areas or inserts (2) provided with a through hole (3), said areas or inserts being made from a second biocompatible polymer which is more malleable than the first polymer, said areas or inserts having mechanical properties allowing a self-tapping of the inner surface of the holes, by means of screws that can be used for securing said plate to bone tissue, said support portion and said areas or inserts having a partial molecular bond between them.
