Active compression devices, methods of assembly and methods of use are disclosed. A bone fixation device may include a first member, a second member shaped to engage the first member, and at least one deformable member. A bone fusion device including a female member with a proximal and distal end, a male member with a proximal and distal end, and at least one elastic element positioned between the female member and the male member. A bone plating device including a first member, a second member shaped to engage the first member, and at least one deformable member positioned between the first member and the second member. Methods of assembling and using the bone fixation devices, bone fusion devices, and bone plating devices are also disclosed.

Disclosed is an osteosynthesis device including at least one fixation pin suitable for being implanted in a bone material so as to ensure an at least partial reduction of a bone fracture, which osteosynthesis device includes a locking unit designed to lock in position the fixation pin implanted in the bone material. The locking unit can include: a support structure provided with a unit that enables its fixing on the bone material, and including a locking aperture suitable for being passed through by the fixation pin; and a clamping designed to be fitted in the locking aperture and to come into abutment against a part of the fixation pin in order to ensure its locking in position.

Various implementations include an adjustable implant such as a distraction/compression device. In certain cases, the adjustable implant can include a housing; an adjustable member at least partially positioned within the housing and configured to translate relative to the housing; and an intermediary member positioned between the housing and the adjustable member.

In one embodiment, the present invention includes an intramedullary osteosynthesis or arthrodesis implant including a central body, a first pair of legs extending from the central body to a pair of leg tips, and a second pair of legs extending from the central body, in a direction opposite the first pair of legs, to a pair of leg tips such that the central body, first pair of legs and second pair of legs are positioned alongside a longitudinal axis.

The present disclosure is directed to a method of surgical repair utilizing a continuous compression staple for an orthopedic injury site having a long bone fracture defining a fracture boundary between a first bone fragment and a second bone fragment. The method can include the steps of aligning the fragments, applying a temporary compressive force to the aligned fragments, inserting a compression staple in a tensioned state into the first and second bone fragments such that it traverses the fracture boundary, releasing tension in the compression staple such that the staple exerts a continuous compressive force to the first and second bone fragments, and securing a neutralization implant to the long bone. The disclosure further includes kits and systems for performing the disclosed surgical methods.

A fixation system for immobilizing a skeletal structure is provided. It includes an internal fixation system having a rod-plate subsystem, a shaft subsystem, and a midfoot plate subsystem. It further includes an external fixation system adapted to connect to the internal fixation system and having a sole that provides a weight-bearing platform underneath a patient's foot to enable a patient to walk with the fixation system.

In described embodiments, an implant assembly includes a first implant having a body with a first end and a second end and a hollow passage extending therethrough between the first end and the second end. The first implant is sized for insertion into a first bone segment. A connector has a first end rotatably connected to the first implant at the first end of the first implant, a second end insertable into a second bone segment, and a connector body extending through the hollow passage of the first connector. A method of inserting the implant assembly is also provided.

A bone fixation assembly may include an elongate fixation member and a flexible tensioning element. The elongate fixation member may include a central longitudinal axis, a distal portion couplable to a first bone fragment of a bone, and a proximal portion couplable to a second bone fragment of the bone to provide fixation of the second bone fragment relative to the first bone fragment. The flexible tensioning element may be couplable to the proximal and distal portions of the elongate fixation member to secure the elongate fixation member to the bone. The flexible tensioning element may be configured to span a bone fracture intermediate the first bone fragment and the second bone fragment to preload the bone fracture in compression to resist tensile force imparted across the bone fracture, thereby maintaining fixation of the first bone fragment relative to the second bone fragment.

A monitoring system includes: (1) an implant having at least one sensor and configured for at least partial insertion into a patient, a first one of sensors being in contact with a perimeter of a hole in a body portion of the implant for accepting a fastener; (2) a microchip associated with the implant and the sensor, the microchip configured to receive at least a first signal from the sensor; (3) a transmitter associated with the microchip for transmitting a second signal, representative of the first signal; (4) a receiver located outside of the patient, the receiver configured receive the transmitted second signal; and (5) a display device associated with the receiver, the display device configured to provide an audible or visual representation of the second signal to a user.

Arthrodesis devices and arthrodesis procedures are disclosed herein. In an embodiment, an arthrodesis device includes a shape memory material connecting member attached to two points of fixation.
