The present invention provides an orthopaedic 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 orthopaedic 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 system for robot assisted surgery can include an imaging device configured to capture an image of an implanted device and a probe. The implanted device can define a hole and the probe can define a hole. The system can also include a robot configured to align a fastener to the hole defined by the implanted device. The system can further include at least one memory that includes computer program instructions and at least one processor. The at least one memory and the computer program instructions can be configured to, with the at least one processor, perform obtaining a position and orientation of the hole defined by the implanted device. The at least one memory and the computer program instructions can also be configured to, with the at least one processor, perform aligning the fastener to the hole using the obtained position and orientation.

Bone plates for engaging bone members are described herein. The bone plates can receive one or more screws to secure the bone plates to an underlying bone member. The one or more screws can be inserted into bone plate holes that can be considered locking or non-locking. The bone plates described herein can have particular combinations of locking and/or non-locking holes. In addition, instruments such as distal and proximal aiming guides can accompany the bone plates to guide one or more screws into the bone plates.

The present invention relates to a guide module having oblique installation pins, the guide module including: a first installation pin unit penetratively inserted into one side of an aligned bone; a second installation pin unit penetratively inserted into the other side of the aligned bone; a reposition guide unit simultaneously penetrated by the first installation pin unit and the second installation pin unit and being simultaneously in contact with one side of the aligned bone and the other side of the aligned bone; and a compression guide unit disposed adjacent to the reposition guide unit and simultaneously penetrated by the first installation pin unit and the second installation pin unit, in which imaginary central axes of holes of the reposition guide unit penetrated by the first installation pin unit and the second installation pin unit are spaced apart, at a predetermined interval in a vertical direction, from imaginary central axes of holes of the compression guide unit. Therefore, the aligned bone may be compressed.

An assembly used in osteosynthesis comprising a delivery instrument in combination with an implant wherein the delivery instrument releasably holds the implant in a first configuration prior to attachment of the implant to bone. The delivery instrument allows the implant to be affixed to bone before the implant is released from the instrument. And the instrument may comprise guide means for drills, depth gauges, screws, pins, pegs, blades and or drivers which are used or implanted when the implant is releasably attached to the instrument. After the implant is affixed to bone and released from the delivery instrument, the implant assumes at least a second configuration which provides compression and or distraction and or control of spatial orientation.

An intramedullary nail implant for positioning in a bone having a head and a shaft defining an intramedullary canal. The implant includes a distal portion having a shaft extending along a central axis and configured for positioning within the intramedullary canal. A proximal portion extends proximally from the distal portion. The proximal portion defines a contact surface which extends at least in part medially of the central axis such that it is configured to extend within a medial portion of the bone head. A method of implanting the nail is also provided.

A system to stabilize and guide the growth of the spinal column includes an elongated support member having a width and a length and a guiding connector having a bone connecting portion and a guiding portion. The bone connecting portion secures the guiding connector to a vertebrae and the guiding portion has a bearing element with a passageway adapted to receive the elongated support member. The bearing element permits relative sliding movement of the elongated support element in the passageway of the bearing element. The system may further include a bone fixation element has an elongated support member receiving channel, a locking mechanism and a bone anchoring portion. The bone anchoring portion secures the bone fixation element to bone. The locking mechanism secures the elongated support member in the channel. The guiding connector is moveable along the elongated support member to permit and control the growth of the spinal column along a predetermined path.

A surgical fixation system including a base plate, a plurality of anchors and a locking element. The base plate has at least a pair of fixation apertures configured to receive at least a portion of the anchors therethrough. The fixation apertures are located within the base plate such that upon proper placement of the base plate within a surgical target site, one of the fixation apertures is positioned over a first bone segment (e.g., a first vertebral body), and the other fixation aperture is positioned over a second bone segment (e.g., a second vertebral body).

An apparatus and methods are provided for a bowed plate for fixating osteotomies and joint arthrodeses. The bowed plate includes a backplate comprising a support portion and an aperture portion that share an intervening central portion. The central portion angles the support portion and the aperture portion toward a midline of the bowed plate. A leg extends from the support portion and includes fixation features that enable the leg to grip an inner wall of a hole drilled in bone. A slanted aperture in the aperture portion is configured to countersink a bone screw. The central portion is configured to be straightened by way of a surgical bending instrument and implanted at a bone fixation or fusion site of a patient. Upon relaxing the surgical bending instrument, the leg and the bone screw compress the fusion site.

A navigation system is disclosed comprising a first and a second tracker support separately affixed to the same rigid object by a distance. A first and a second plurality of trackable elements are secured to the first and second tracker supports, respectively. The navigation system defines a tracking arrangement to be tracked based on a combination of the first and second plurality of trackable elements. A geometry of the tracking arrangement relative to the rigid object is registered. The navigation system has a localizer configured to track the rigid object by detecting the registered geometry of the tracking arrangement. The navigation system identifies a condition wherein at least one trackable element has been displaced relative to the registered geometry, and in response, generates a response to address the condition.
