Bone plate and instrument systems include interconnections and locking mechanisms to fix the bone plates to the instruments, and guide features that aim k-wires, drills, and/or fasteners to pass through holes in the bone plates when the bone plates are fixed to the instruments. The locking mechanisms include elongated flexible elements that connect to the bone plates.

Devices, systems, and methods of bone stabilization. The bone stabilization system includes a bone plate having an upper surface and a lower surface configured to be in contact with bone, the bone plate having an opening extending from the upper surface to the lower surface. The opening is configured to receive a fastener, which may be either a locking fastener or a compression fastener. The locking fastener has a threaded head portion configured to engage and lock to the bone plate, and the compression fastener is configured to dynamically compress the bone.

A plate assembly for stabilizing a bone is provided. The plate assembly includes a fixation plate having rails that form a window. The plate assembly includes a band having a tail and a head. The head defines an internal cavity configured to receive a portion of the tail. The fixation plate is configured to be positioned proximate to a bone. The head is configured to be at least partially received within the window. Further, the band is configured to be wrapped around the fixation plate and the bone, and the internal cavity of the head is configured to receive an end of the tail to form a loop. The band is configured to receive a tension force to tighten the loop formed by the band. The band may passively engage the fixation plate so that bands may be easily removed from windows when no tension is applied to the band.

The present disclosure provides methods for forming or enlarging holes in objects. Objects may include bone tissue and methods for fixing matched medical plates to bodies. The movable trocar with toroidal interface is adjustable relative to the surface. The present disclosure also provides for products produced by the methods of the present disclosure and for apparatuses used to perform the methods of the present disclosure.

A technique of providing user guidance for surgical navigation is provided. A method implementation of the technique includes obtaining a predetermined spatial relationship between an optical tracking pattern and a through-hole extending through an implant, obtaining image data of the optical tracking pattern acquired by an imaging unit attached to a surgical instrument, obtaining a spatial relationship between the surgical instrument and the imaging unit at a point in time when the image data have been acquired, determining a spatial relationship between the surgical instrument and the through-hole, obtaining a plurality of predefined spatial relationships between the surgical instrument and the through-hole, and triggering simultaneous display of an indication of the plurality of predefined spatial relationships and an indication of the spatial relationship between the surgical instrument and the through-hole.

A bone plate comprises a plate body and at least one tab. The plate body defines an inner body surface configured to face an underlying bone, an outer body surface opposite the inner body surface, and an outer side surface that extends between the inner body surface and the outer body surface. The outer side surface defines an outer perimeter of the plate body. The at least one tab includes a head and an arm that extends from the plate body to the head. The tab defines a tab aperture that extends through the head and is configured to receive a bone anchor. The bone anchor can be coupled with a screw hole in the nail. The arm is configured to deflect with respect to the plate body so as to move the head between a pre-fixation position and a fixation position spaced from the pre-fixation position.

A radially compressive implant, which includes a central vertical axis, is configured to transition between a natural shape and an insertion shape. A transition of the implant from the natural shape to the insertion shape facilitates the implant storing energy deliverable radially relative to the central vertical axis. A transition of the implant from the insertion shape toward the natural shape facilitates the implant delivering the energy stored therein radially relative to the central vertical axis. An implant delivery device in an implant engagement position is configured to engage the implant and constrain the implant in the insertion shape. The implant delivery device in an implant release position is configured to release the implant.

The invention relates to a plate fixed between two bone parts by way of screws engaged in holes formed in the thickness of said plate. The plate comprises an angled member or rib which is inclined according to an angle of between about 30° and 60° in relation to the plane defined by the plate. The angled member or rib has a hole for engaging a screw and is located in the central part of the width, over a determined part of the length of the plate, so that the screw brings the two bone parts into a compressive position.

A surgical instrument includes a first member defining an axis and a second member having at least one capture element. The at least one capture element being axially translatable relative to the first member such that the at least one capture element is outwardly radially movable relative to the axis and inwardly radially movable relative to the axis to capture a spinal plate. Systems, implants and methods are disclosed.

A pectus bar pectus bar assembly can include a pectus bar and a stabilizer. The pectus bar can include a first portion including a first periphery and a second portion opposite the first portion. The stabilizer can include a stabilizer body including a recess engageable with the second portion. The stabilizer can also include a locking cam rotatable within the body to secure the stabilizer to the first portion.
