A bone anchor includes an anchor member including a first material, and having a tubular section extending along a longitudinal axis, a region configured to expand radially outwards from the longitudinal axis, and a bone engagement structure projecting from at least a portion of the expandable region of the tubular section, and a core member including a second material, and configured for insertion into and connection to the anchor member. When the core member is in the anchor member and is actuated relative to the anchor member, the tubular section is adjustable between a first position where the expandable region of the tubular member has a first length and a first maximum diameter, to a second position where the expandable region of the tubular member has a length shorter than the first length and a maximum diameter greater than the first maximum diameter.

An adjustable occipital plate includes a fixation plate, at least one lateral rod configured to be coupled to said fixation plate, at least one laterally sliding link configured to be coupled to and configured to be compressed around said at least one lateral rod to create a friction fit, and at least one rod connector coupled to said at least one laterally sliding link that is configured to receive at least one posterior cervical rod.

The present invention provides a spinal plate which is used to perform fixation surgery on a spine in orthopedic surgery and neurosurgery. The spinal plate comprises a central body and a pair of rotation portions which are disposed on both sides in a longitudinal direction of the central body and each of the pair of rotation portions has bone screw. The spinal plate also comprises spike screw in each of the pair of rotation portions. Each of the pair of rotation portions include a rotation connection portion, and the central body includes a rotation support portion. Rotation pins are used to connect the central body with the pair of rotation portions disposed on both sides in a longitudinal direction of the central body and enable the pair of rotation portions to rotate clockwise or counterclockwise with respect to the central body.

An occipital plate and hinged rod assembly. The occipital plate having a screw-attachment section having through holes for securing the occipital plate to a skull, a laterally-extending section, a tulip connector, a slide clip disposed underneath the laterally-extending section and engaging a base of the tulip connector, and an insert ring encompassing side walls of tulip connector. The laterally-extending section, the tulip connector, the slide clip, and the insert ring have respective surfaces with complementary curvatures that fit together. The hinged rod assembly is connected to the occipital plate by rods.

An anchoring system for implanting in bone, the system comprising a first coupling assembly having a first clamp and a first coupling body that receives and holds a first stabilization element; a second coupling assembly that receives and holds a second stabilization element; and a plate that attaches to the first coupling assembly and the second coupling assembly, wherein the first coupling assembly attaches to a bone fastener, and wherein the first coupling body includes a cap retainer that receives a locking cap that applies a directional force to force the first coupling body toward the plate, and applies another directional force to force the first clamp toward the plate, thereby fixedly securing the first coupling body and the first clamp to the plate.

The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region is generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.

Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member. The distal portion of the wing can define a bone anchor opening through which one or more auxiliary bone anchors can be disposed to augment the fixation of the assembly's primary bone anchor. A distal surface of the distal portion of the wing can be obliquely angled relative to a proximal-distal axis of the spanning portion to face one of a caudal direction or a cephalad direction. A distal surface of the distal portion of the wing can be obliquely angled relative to the proximal-distal axis of the spanning portion to face one of a medial direction or a lateral direction. Surgical methods using the bone anchor assemblies described herein are also disclosed.

Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a plate that is seated between the receiver member and the rod and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a hook that extends out from the receiver member to hook onto an anatomical structure or another implant to augment the fixation of the assembly's primary bone anchor. Surgical methods using the bone anchor assemblies described herein are also disclosed.

A surgical implant includes a first portion and a second portion. The first portion includes a body and connector assemblies. The body includes a posterior surface and defines a first bore defining an acute angle with respect to a first axis that is orthogonal to the posterior surface. The connector assemblies are disposed on opposing lateral sides of the body. Each connector assembly is selectively rotatable relative to the body. The second portion includes a base extending in a cephalad direction from the first portion, and an extension extending in the cephalad direction from the base. The base defines second bores configured to receive respective bone screws. The extension defines a third bore. The first bore of the body and the third bore of the extension define a second axis. The second bores are defined along a third axis orthogonal to the second axis.

A system, medical devices, and methods for use in surgical procedures, such as spinal surgeries. The system, medical devices, and methods are designed to provide a surgeon the ability to add a screw connector, or screw head such as a tulip, to pre-existing implanted bone, such as pedicle, facet, lateral mass, etc., screw system without having to remove the previously implanted screws and/or rods already existing in a patient.
