An adjustable implant includes a body portion including a first end, a second end including a bull nose, and a sidewall extending from the first end to the second end, a hook coupled to the body portion, the hook including a first hook portion extending from the body portion in a first direction, and a second hook portion extending from the first hook portion in a second direction that is different from the first direction, a first wing coupled to the first end of the body portion, and a second wing coupled to the body portion such that the distance between the first wing and the second wing is adjustable by a user, wherein the first and second wings include inward facing surfaces configured to be positioned adjacent portions of bone of a patient.

Embodiments herein are generally directed to spinal implants for use in orthopedic stabilization assemblies. In some embodiments, these implants may be used in conjunction with laminoplasty or laminectomy procedures.

A bone clamp for securing of a measurement aid to a bone comprises a first clip and a second clip and an adapter. The adapter comprises a pulling mechanism and a locking mechanism, whereby the position of the first clip relative to the second clip can be altered by actuation of the pulling mechanism, wherein the position of the first clip relative to the second clip can be fixed by actuation of the locking mechanism. The first clip and the second clip each have an inner face which is oriented in the direction of the bone, wherein the first clip has one or more spikes on the inner face and wherein the second clip has a sliding edge on the inner face.

To provide a spinal fusion system that applies a stable fixing force to a spine.

In a spinal fusion system 1A, a lamina having relatively high strength in an entire vertebra can be engaged to be held from a head side and a tail side by a pair of first and second hook members 3 and 4. Consequently, a fixing force to a spine can be improved and a stable fixing force can be applied to the spine.

Systems and methods for en bloc derotating a spinal column are provided. In one exemplary embodiment, the method can include manipulating first and second frames coupled respectively to a first set of vertebrae and a second set of vertebrae to derotate the first and second sets of vertebrae relative to one another, and subsequently locking a linkage assembly coupled respectively to the first and second frames to maintain the first and second sets of vertebrae in a derotated position.

Apparatus, consisting of a hinge defining a hinge axis, and a pair of opposing jaws, including a movable jaw and a fixed jaw having a predetermined part radiopaque, so that the fixed jaw location is identifiable from a fluoroscopic image of the fixed jaw. The opposing jaws terminate at proximal and distal regions, and the proximal regions are connected to the hinge so that the movable jaw rotates about the hinge between a jaws closed state and a jaws open state. The jaws are curved in planes parallel to the hinge axis, and terminate in narrowed ends at the distal regions, so that in the closed state the jaws grip one or more sections of vertebrae. The apparatus also has a support structure that retains the hinge and the pair of opposing jaws, and a multiplicity of sharp teeth disposed on respective inner surfaces of the opposing jaws.

Surgical instruments, methods, and systems are provided for securing spinal fixation elements to bone. For example, a spinal fixation system is provided that has a receiver with proximal and distal ends. The proximal end of the receiver is configured to receive various fixation members, such as spinal rods and set screws, therein. The distal end of the receiver has a hook member that is operably coupled thereto and has an opening that is configured to receive bone therein. The hook member is configured to be secured to bone without penetrating the bone.

An adjustable spine distraction implant alleviates pain associated with spinal stenosis and facet arthropathy by expanding the volume and/or cross sectional area in the spinal canal and/or neural foramen. The adjustable implant provides a spinal extension inhibitor. The implant includes elliptical or oval shaped adjustable member or spacer for positioning between and adjustably spacing apart the spinous processes.

Embodiments herein are generally directed to spinal implants for use in orthopedic stabilization assemblies. In some embodiments, these implants may be used in conjunction with laminoplasty or laminectomy procedures.

A spinal stabilization system may include at least one pedicle screw comprising a threaded base to be connected to a superior pedicle of a vertebra and a screw head attached to the threaded base. The system may further include at least one pars interarticularis clamp comprising an elongate body defining a screw head connection point to be connected to the screw head of the pedicle screw, and a laminar hook coupled to the elongate body and configured to wrap around an edge of the lamina and compress the pars interarticularis of the vertebra when the screw head connection point is connected to the screw head.
