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.

Composite internal fixators

In one general aspect, an orthopaedic fixation device includes an inner core and shaft formed of a multi-layered, fiber-reinforced composite. A sensing element is embedded within the multi-layered, fiber-reinforced composite.

Fiber-reinforced composite orthopaedic device having embedded electronics

A multi-layer, fiber-reinforced composite orthopedic fixation device having a design selected based on a desired characteristic of the orthopedic 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.

Embodiments of the present invention provide a bone fixation assembly that can provide polyaxial fixation. The polyaxial fixation may be provided by fins that protrude from an opening in a bone plate or fins that protrude from a fastener head.

Systems and methods for using polyaxial plates

In one general aspect, an orthopedic fixation device includes an inner core and shaft formed of a multi-layered, fiber-reinforced composite. A sensing element is embedded within the multi-layered, fiber-reinforced composite.

A medicament containment device () is provided containing a medicament () and is associated with an implant, such as an orthopedic implant (). The medicament containment device () can degrade upon exposure to energy, such as energy () from an energy source (). The orthopedic implant (), including the medicament containment device is implanted or inserted into an environment () such as a patient's body. The energy source () can be used outside the patient's body, but in proximity to the orthopedic implant (), to apply energy () to the medicament containment device (). Upon exposure to the energy (), the medicament containment device () can degrade and release the medicament () into the environment (). The medicament () can kill and/or disrupt bacterial cells () or other infectious cells that form in proximity to the orthopedic implant ().

Systems and methods for delivering a medicament

A system () for identifying a landmark is disclosed. The system includes a field generator () for generating a magnetic field, an orthopedic implant () located within the magnetic field, the implant having at least one landmark (), a removable probe () with a first magnetic sensor (), a landmark identifier () with a second magnetic sensor () and a processor () for comparing sensor data from the first and second sensor and using the set distance to calculate the position of the landmark identifier relative to the at least one landmark. The system allows for blind targeting of one or more landmarks.

System and method for identifying a landmark

Systems for bone fracture repair are disclosed. One system includes a biocompatible putty that may be packed about a bone fracture to provide full loadbearing capabilities within days. The disclosed putties create an osteoconductive scaffold for bone regeneration and degrade over time to harmless resorbable byproducts. Fixation devices for contacting an endosteal wall of an intramedullary (IM) canal of a fractured bone are also disclosed. One such fixation device includes a woven elongated structure fabricated from resorbable polymer filaments. The woven elongated structure has resilient properties that allow the woven structure to be radially compressed and delivered to the IM canal using an insertion tube. When the insertion tube is removed, the woven structure expands towards its relaxed cross-sectional width to engage the endosteal wall. The woven elongated structure is impregnated with a resorbable polymer resin that cures in situ, or in the IM canal.

Fracture fixation systems

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

Orthopedic fracture repair implants, systems and methods are disclosed. Implants include one or more of biocompatible sleeves and struts. The implants, systems and methods are applied to bone fractures, such as segmentation fractures.

Fracture fixation systems having intramedullary support

A method for targeting a landmark of an orthopaedic implant comprises implanting the orthopaedic implant in a body. The orthopaedic implant having at least one landmark defining two or more locations for targeting and a first magnetic sensor located at a known distance from at least one of the two or more locations. The method includes comprises identifying one of the locations using a landmark identifier, the landmark identifier having at least one of a second magnetic sensor and a magnetic field generator, installing a transfixion element in the at least one landmark, and identifying a second location using the landmark identifier.

Targeting landmarks of orthopaedic devices

Surgical instruments and procedures are disclosed that enable the injection of an optimal amount of curable resin and/or the placement of an internal fixation device in an intramedullary canal of a fractured bone. The disclosed instruments and procedures enable a surgeon to clear a portion of the canal of cancellous bone and marrow across the fracture site without damaging the cortical wall.

Surgical instruments for cutting cavities in intramedullary canals

A system () for identifying a landmark is disclosed. The system includes a field generator () for generating a magnetic field, an orthopaedic implant () located within the magnetic field, the implant having at least one landmark (), a removable probe () with a first magnetic sensor (), a landmark identifier () with a second magnetic sensor () and a processor () for comparing sensor data from the first and second sensor and using the set distance to calculate the position of the landmark identifier relative to the at least one landmark. The system allows for blind targeting of one or more landmarks.
