Spring retained femoral augment
An orthopedic system that includes a first augment that has a body and a first biasing member projecting from the body. The body has a first and second face. The first and second faces are separated by a thickness of the augment. The system also includes a femoral prosthesis that has an articular side that defines condylar portions and a bone-facing side opposite the articular side. The bone facing side defines an augment opening that is sized to receive the augment therein. When the first augment is received within the augment opening, the first biasing member presses directly against the femoral prosthesis so as to retain the body within the augment opening.
Inflatable non-distracting intervertebral implants and related methods
Inflatable orthopedic implants and related methods are disclosed herein, e.g., for deploying such implants within an intervertebral space for use in spinal fusion surgery, other intervertebral surgical procedures, or other surgical procedures. The inflatable intervertebral implant can include a hollow inflatable body that can be configured in a compact state for insertion into a target intervertebral space between a pair of adjacent vertebral bodies. Once the vertebral bodies are separated or distracted, e.g., using one or more inflatable distractors, the hollow body of the inflatable implant can be inflated with bone cement or other curable material. When the curable material hardens, the inflated implant can form a rigid intervertebral support structure (e.g., a fusion cage) capable of maintaining the vertebral distraction and thereby enabling removal of the distractors.
ROBOTIC SURGERY
A method of using a robotic guidance system for performing surgery on a spine is provided. The method includes utilizing a computerized tomographic scan image of a location on a spinal column of a patient, such that the computerized tomographic scan image is connected to a computer and visible on a monitor connected to the computer. The method also includes attaching a coupling component to the spinal column of the patient, coupling a marker to the coupling component, and imaging, with a fluoroscope, the view of the spinal column of the patient, wherein the fluoroscope image is transmitted to the computer and visible on the monitor and the at marker is clearly visible in the fluoroscope image. The method also includes positioning a cannula, with a robotic mechanism, to a first position relative to a vertebra in the spinal column of the patient, drilling a passage through the cannula into bone of the vertebra in the spinal column of the patient, inserting a guidewire through the cannula into the passage in the bone of the vertebra in the spinal column of the patient, and positioning a screw into the bone of the vertebra in the spinal column of the patient.
EXPANDABLE SPINAL IMPLANT SYSTEM WITH A BIASED TIP AND METHOD OF USING SAME
An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.
SPINAL IMPLANT SYSTEM AND METHODS OF USE
A method for treating a spine comprises the steps of: inserting a surgical instrument into a tissue cavity, the surgical instrument including an image guide oriented relative to a sensor to communicate a signal representative of a position of the surgical instrument relative to the tissue cavity; displaying a selected configuration with a distal end of the surgical instrument in the tissue cavity; tracking movement of the selected configuration in the tissue cavity with a tracking device that communicates with a processor to generate data for display of the movement; and determining a volume of the tissue cavity based on the data. Systems, spinal constructs, implants and surgical instruments are disclosed.
Interpositional Joint Implant
A method of preparing an interpositional implant suitable for a knee. The method includes determining a three-dimensional shape of a tibial surface of the knee. An implant is produced having a superior surface and an inferior surface, with the superior surface adapted to be positioned against a femoral condyle of the knee, and the inferior surface adapted to be positioned upon the tibial surface of the knee. The inferior surface conforms to the three-dimensional shape of the tibial surface. The implant may be inserted into the knee without making surgical cuts on the tibial surface. The tibial surface may include cartilage, or cartilage and bone.
PROCESS FOR INTRODUCING A STABILIZING ELEMENT INTO A VERTEBRAL COLUMN
A process for introducing a stabilizing element into a vertebral column, in which the stabilizing element is introduced in such a manner that the stabilizing element connects two adjacent vertebral bodies to one another.
Device and kit for positioning an implant for intervertebral fusion
A device for positioning an implant for intervertebral fusion, comprising: a handle; a rod protruding from the handle along a main direction of extension of the device up to a free end; a coupler which couples with an implant for intervertebral fusion operatively active at the free end; wherein said coupler comprises: an axial retention assembly provided with a gripper arranged at said free end of the rod and selectively operable between a clamping and a releasing configuration, and an anti-rotational constraint assembly selectively movable between a locking position, in which it is arranged around said axial retention assembly and abuts said implant to prevent its rotation, and a disengagement position, in which it leaves the implant free to rotate in the gripper; and wherein the axial retention assembly and the anti-rotational constraint assembly are structurally different and complementary.
DEVICE AND METHOD FOR CORRECTING SPINAL DEFORMITIES IN PATIENTS
Devices and related methods for the dynamic correction of spinal deformities are disclosed. The devices and methods are particularly useful for correcting an abnormal curvature of the spine. In one exemplary embodiment, a method for correcting deformity via a spinal implant that can include a polymer between or attached to a top and bottom plate, which can exist in a wedge-shaped configuration in order to apply asymmetric forces to the spinal column, is provided. The implant may be inserted between adjacent vertebrae comprising part of the abnormal curvature, thereby restoring the normal curvature of a spine.
Rotating implant and associated instrumentation
A system for use during surgical procedures. The system includes an implant and an inserter. The implant has a faceted post that rotates, ribs adapted to receive impact from an instrument to help position the implant, and stops. The inserter has a sleeve, into and from which a hook retracts and extends and on which a tab is disposed, and a pair of catches. The hook and tab combine to lock the post into position and to release the post so that the post can rotate. The engagements between the hook and the post and between the tab and the post permit rotation of the implant in situ. The stops and catches define an articulation range for the implant relative to a longitudinal axis of the inserter. A related method of using the system is also provided.
