摘要:
A posterior spinal fixation device or dynamic spinal stabilization device or other orthopedic device includes an active agent-delivery component. The active agent-delivery component has an active agent impregnated therein or adsorbed thereon or otherwise contained therein and is configured to release the active agent locally after the device is implanted in a patient. One preferred type of implant in accordance with the invention is an implant for stabilizing a spinal motion segment that includes a spacer member positionable between adjacent spinous processes or transverse processes or other posterior spinal element, including an implanted anchor element.
摘要:
A method and apparatus for determining, calculating, and/or viewing a trajectory. The trajectory can be displayed on a display relative to image data of a patient. A user can use the system to determine relationships between two or more trajectories that have been determined. The relationships can be within two dimensional, three-dimensional, or four dimensional space. The relationships can include distance, angle, etc. The relationships can also be determined between real time trajectories and stored trajectories, or combinations thereof.
摘要:
A multi-piece intervertebral disc augmentation implant that may be assembled within the annulus fibrosus is disclosed. The implant may be guided into a precise location through a relatively small opening in the annulus fibrosus with the aid of an elongated guide.
摘要:
A method for anchoring a portion of material to bone is disclosed. One such method comprises inserting the portion of material through a hole in a fastener, and driving the fastener into the bone such that the portion of material becomes anchored to the bone such that driving the fastener farther into the bone increases tension in the material.
摘要:
An intervertebral prosthesis implantable within a disc space and disposed between upper and lower vertebral endplates is provided. The prosthesis comprises a plurality of prosthesis components insertable into the disc space, wherein the components have at least one set of complementarily-shaped and sized surfaces, and wherein the at least one set of complementarily-shaped surfaces comprises a slot, and a rod that fits in the slot. A method of implanting an intervertebral prosthesis according to the present invention also is provided.
摘要:
Devices and methods for spinal stabilization include first and second anchor assemblies engageable to respective ones of first and second vertebrae and a connecting element engageable to the first and second anchor assemblies. The connecting element includes opposite first and second members and a dampener between the end members that provides a flexible bumper between the end members to provide dynamic stabilization of the spinal column when engaged to the anchor assemblies.
摘要:
A molding device is disclosed and can include a first mold component and a second mold component substantially opposite the first mold component. The first mold component and the second mold component can fit around a superior spinous process and an inferior spinous process.
摘要:
An adjustable interspinous process brace is disclosed and can include a superior component. The superior component can include a superior spinous process bracket that can engage a superior spinous process. Further, the adjustable interspinous process brace can include an inferior component. The inferior component can include an inferior spinous process bracket that can engage an inferior spinous process. Further, the inferior component can be movably engaged with the superior component from a retracted position to an extended position. In the extended position, a distance between the superior spinous process bracket and the inferior spinous process bracket can be increased.
摘要:
A prosthetic assembly and method of implanting same, according to which a least one rod is secured to the spinal column. A spacer engages the spinous process of a vertebrae of the spinal column. The rod is connected to the spacer via an adapter.
摘要:
One embodiment of the present application includes: performing a medical procedure on a segment of a patient's spine. This segment includes two vertebrae each in contact with a spinal disk positioned in an intervertebral disk space. A passage is formed that follows a pathway through the vertebrae and the intervertebral disk space. This passage extends from an extradiscal opening through one of the vertebrae along a path that turns to change direction. The tubular device is inserted in the passage and extends through the intervertebral disk space. A fluid material is introduced into the tubular device to at least partially fill it to provide a spinal prosthetic structure. Other embodiments and inventive aspects include other prosthetic device arrangements, implantation methods, systems, and techniques.
