Disclosed herein is a self-countersinking bone screw and a system and a method for countersinking a bone screw or fastener used in connection with an orthopedic implant such as, for example, an intramedullary nail. The bone screw includes one or more cutting features configured to self-countersink the head of the screw. The system and method utilize instrumentation including a plurality of markings or indicia configured to indicate a position of the head of the screw relative to an outer surface of the patient's bone. In use, the method enables a surgeon to quickly and easily countersink one or more bone screws used to couple an IM nail to a patient's bone without requiring additional instrumentation to form a countersunk hole in the patient's bone.

Self-countersinking bone fastener and method for countersinking a bone fastener used in connection with an orthopedic implant

An orthopedic device, such as an intramedullary nail for internal fixation of a bone and a method of manufacturing the same. The orthopedic device may be formed from a medical grade powder via an additive manufacturing process. The forming process may include heat treating the additive manufactured component and machining the heat treated additive manufactured component to form the orthopedic device. Further, the orthopedic device may be formed to include an internal sensor probe channel that extends within at least a portion of the wall of the device, but which does not protrude through an outer portion of the wall. Embodiments further include a dynamizing intramedullary nail that accommodate adjustments in the relative axial positions of one or more sections of the orthopedic device. The devise may include features in an inner region of the orthopedic device that may alter an elastic modulus of the orthopedic device.

A tissue protection sleeve for use in trauma surgery is disclosed. In various embodiments, the tissue protection sleeve includes an inner sleeve with a first end portion, a second end portion, a longitudinal axis, and a bore extending there through, and an outer sleeve at least partially surrounding and coupled to the inner sleeve, wherein the tissue protection sleeve is capable of flexing or bending without collapsing the bore. In some embodiments, the inner sleeve may include a number of distinct geometries to provide sufficient structural rigidity, whilst still allowing the inner sleeve to bend. Additionally, a tissue protection sleeve handle may be coupled to the tissue protection sleeve to allow for manipulation of the tissue protection sleeve. In certain embodiments, pin guide holes or channels may be used to secure the tissue protection sleeve to a patient's bone.

Tissue protection sleeve

A multi-layer, fiber-reinforced composite orthopaedic fixation device having a design selected based on a desired characteristic of the orthopaedic fixation device. The design may be selected according to a model of the device, the model defining design constraints, and the design may comprise a pattern of the fiber angle for each layer. The selection of a design may be analyzed using finite element analysis to determine whether the design will comprise the desired characteristic.

The design may be selected according to a model of the device, the model defining design constraints, and the design may comprise a pattern of the fiber angle for each layer. The selection of a design may be analyzed using finite element analysis to determine whether the design will comprise the desired characteristic.

An orthopaedic implant includes a body being elongated in a longitudinal direction and having an outer wall, one or more openings through the outer wall, and a cannulation disposed along a length of the body and defined by the outer wall, the cannulation being non-uniform along the longitudinal direction, wherein the cannulation is configured such that a moment of inertia of the implant is substantially uniform along the longitudinal direction.

Reducing implant stress zones

The present disclosure relates to systems and methods for installing shape memory polymers relative to orthopedic implants.

Systems and methods for installing and removing an expandable polymer

An orthopedic implant including a body defining at least one landmark and a probe comprising a sensor spaced apart from the at least one landmark a set distance. The probe and sensor being releasably fixed to the body of the implant to limit movement of the sensor relative to the at least one landmark.

A fracture fixation systemfor a fractured bone having at least two bone fragments is disclosed. The fracture fixation systemincludes an orthopaedic implant, an engaging memberadapted to gain purchase in at least one bone fragment, and means for applying a force to the engaging member such that the at least two bone fragments are placed in compression and prevented from rotating relative to the orthopaedic implant. The engaging memberis disposed relative to the orthopaedic implant. The orthopaedic implantmay take the form of an intramedullary device, a compression plate, or a deployable material.
