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.

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 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.

A cervical spine plate attachment system includes a cervical spine plate that has a first surface configured to rest upon a first vertebra and a second vertebra, a second surface opposite the first surface and facing away from the first vertebra and the second vertebra, and a plurality of holes configured to receive fasteners to secure the cervical spine plate to the first vertebra and the second vertebra. The system also includes an alignment guide that detachably mounts to the cervical spine plate. The alignment guide comprises a pair of bars that rest upon the second surface of the cervical spine plate when the alignment guide is mounted to the cervical spine plate. The system also includes a fastener configured to secure the alignment guide to the cervical spine plate.

The present invention relates to a surgical device of repère configured to be connected to a vertebral spinous process of a patient. The main body includes a skin contact element, having an abutment surface shaped to abut on the skin overlying the vertebral spinous process; handling means connected to the skin contact element, configured to allow the adjustment of the coupling between the device and the vertebral spinous process; and coupling means with the spinous process of the patient, connected to the skin contact element at the abutment surface and shaped to penetrate the external surface of the vertebral spinous process and insert at least partially inside thereof. The surgical device further has position indicating means connected or connectable to the main body to indicate the penetration point of the-coupling means in the vertebral spinous process.

The present invention provides a spinal plate which is used to perform fixation surgery on a spine in orthopedic surgery and neurosurgery. According to the present invention, a rotation device and a locking device may be installed so as to be used by fixing any one or more of longitudinal ends of the plate with being rotated at any angle, thereby allowing a doctor to modify a shape of the spinal plate to the shape desired by the doctor, and to perform the surgery by coping with various spin shapes of patients. In addition, according to the present invention, since the shape of the spinal plate may be rotated at any angle, it is possible to cope with various spin shapes of the patients.
