Anterior cervical plate
An anterior cervical includes a plate portion for stabilizing a human or animal spine by being placed ventrally of the spinal column and affixed to two or more different vertebral bodies, and a plurality of fastening portions adapted to be anchored in the different vertebral bodies. At least one of the fastening portions is rigidly connected to the plate portion and includes a sheath element with a longitudinal opening that is accessible from a proximal side and at least one hole that reaches from the longitudinal opening to an outside. The anterior cervical plate further includes a thermoplastic element that may be inserted in the sheath element and that is capable of being liquefied by, for example, mechanical energy acting on the thermoplastic element.
Bone fixation system and method of use
An apparatus includes: a member configured to be received within an intramedullary canal of a fibula, the member having an opening therethrough; a bone plate including a first bone-engaging surface; a flexible elongate element having a first portion, a second portion, and a third portion, at least the second and third portions being sized to extend through the opening of the member, wherein the second portion is movable by bending of the flexible elongate element between an insertion position and a bone-engaging position, wherein the second portion is configured to extend through the opening of the member while the second portion is in the insertion position, and wherein the second portion includes a second bone-engaging surface while the second portion is in the bone-engaging position; and a coupling structure for operatively coupling the bone plate to the first portion of the flexible elongate element.
Methods of long bone repair utilizing continuous compression implants
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.
DIFFERENTIAL COMPRESSION BONE SCREW
A differential compression bone screw and a method are provided for compressing adjacent bone portions together to encourage bone fusion. The compression bone screw is comprised of a head portion and a shank. A center hole extends from the head portion to a distal end of the shank. A superior end of the head portion includes a shaped opening that receives a tool for driving the compression bone screw into a hole drilled in a patient's bone. An inferior end of the head portion includes barbs that engage with surrounding bone tissue. A smooth portion of the shank is disposed between proximal threads and distal threads that rotatably engage within the hole in the patient's bone. A thread pitch of the distal threads is greater than a thread pitch of the proximal threads, such that the compression bone screw comprises a differential pitch configured to compress the adjacent bone portions.
ORTHOPEDIC PLATE, ORTHOPEDIC DEVICE, METHOD OF COUPLING BONE SEGMENTS, AND METHOD OF ASSEMBLING AN ORTHOPEDIC PLATE
An orthopedic plate comprising a frame portion having a longitudinal body defining a longitudinal axis. The longitudinal body having at least one side arm extending from the longitudinal body transverse to the longitudinal axis. The frame portion also having a bearing rotatably coupled with the at least one side arm, wherein the bearing defines an opening configured to receive a fastener for fastening the orthopedic plate to a body. The bearing includes an outer surface that is eccentric to the opening such that a position of the opening with respect to the frame portion is adjustable as the bearing rotates.
Variable angle blade plate system and method
A bone fixation system having a plate with an axle and a blade or “beam” configured to engage with the axle and reside proximate to a subchondral fragment of bone in upon installation of the plate. The beam is operable to rotate about the axle on the plate and reposition the subchondral fragment of bone.
Bone-stabilizing device having a pivotable buttress member
Devices and methods for stabilizing bone. An exemplary device may comprise a plate, an arm, and a buttress member. The plate may define one or more apertures configured to receive one or more fasteners that secure the plate onto a first bone region. The arm may project from an edge of the plate. The buttress member may be connected pivotably to an end of the arm. The buttress member may be configured to be pivoted by contact with a second bone region to conform an orientation of the buttress member to the second bone region, and may apply compression to, and/or support, the second bone region.
VARIABLE ANGLE CANNULATED BONE SCREW AND METHODS FOR USE THEREOF
A bone screw and a method for using same, the bone screw comprising an elongated shaft including a proximal end, a distal end, a leading portion, and intermediate portion and a trailing portion, the elongated shaft defining a longitudinal axis; a cannula bored completely through said elongated shaft extending from said distal end to said proximal end, the cannula aligned with said longitudinal axis; the leading portion having at least one thread; the intermediate portion being unthreaded; and the trailing portion comprising a threaded tapered head adapted engage a threaded hole at a selectable angle.
SPINAL STABILIZATION DEVICE, SYSTEM, AND METHOD OF USE
A spinal stabilization device includes a rod receiving member, a collet, a plug, and a first bone screw. The rod receiving member defines a first throughhole, a collet recess aligned with the first throughhole, and a rod receiving slot offset from the first throughhole. The collet is insertable into the collet recess and defines an aperture, a plug recess aligned with the aperture, and a wall portion defining a rod securing slot configured to fix the spinal rod therein. The collet is transitionable between a first diameter, where the rod securement region defines a first diameter, and a second diameter, where the rod securement region defines a second diameter. The plug is insertable within the plug recess, and transitions the collet between the first and second diameters. The first bone screw includes a head portion and a threaded portion, and is insertable through the rod receiving member and the collet.
BONE FIXATION DEVICES
There is a fixation device for promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, comprising a bone plate portion including an outer surface, an inner surface and at least one fixation aperture extending from the outer surface to the inner surface and a bone wedge portion extending from the plate portion at a first end and a free opposite end, the bone wedge portion comprising a porous architecture configured to promote bone ingrowth, the wedge portion defining first and second engagement surfaces for engaging the first bone segment and a second bone segment, respectively. There is also a method of manufacturing a fixation device for promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, a method of promoting fusion and/or osteosynthesis of a first bone segment and a second bone segment, and a fixation kit.
