The embodiments provide a spinal implant (10) that is configured for midline insertion into a patient's intervertebral disc space. The spinal implant (10) may have a body and the body comprises one or more apertures (26). The apertures (26) receive fixation elements (40), such as a screw and the like. The fixation element may comprise one or more anti-backout features, such as a split ring. In addition, at least some of the apertures are designed to permit a predetermined amount of nutation by a fixation element. The apertures that allow nutation enable the fixation element to toggle from one position to another, for example, during subsidence of the implant in situ. Some of the apertures may be configured to rigidly lock with the fixation elements. Moreover, the spinal implant may include features, such as one or more bores, that can accommodate imaging marks to help guide a surgeon.

Disclosed are devices and methods for emplacement of an expandable device in a body part of interest in human and animal subjects. In one embodiment, the expandable device comprises a cage that may be emplaced in the intervertebral disc for use in spine fusion techniques. The device is fashioned so that it may be delivered to the intervertebral disc by percutaneous means, such as via a cannula. Additionally disclosed are systems and kits employing the devices of the invention as well as methods of manufacturing the devices of the invention.
摘要:
A dynamic device for implantation within a disc space between two adjacent vertebral bodies is disclosed. The device comprises two or more bodies interconnected via at least one connecting means such that at least one body is permitted relative motion with respect to the at least one other body. The device is configured to assume various configurations including a first configuration suitable for minimally invasive insertion and a second configuration suitable for residence within the disc space. Associated variations and insertion instruments are also disclosed.
摘要:
Um bei einer Augmentationskomponente (1) zur Auffüllung von Knochendefekten mit einer metallischen, porösen Struktur einerseits eine hohe Festigkeit der Augmentationskomponente (1) zu erhalten und andererseits das Einwachsen von Knochenmaterial in das gesamte Volumen der Augmentationskomponente (1) zu fördern, wird vorgeschlagen, dass die Augmentationskomponente (1) aus einem dreidimensionalen Gerüst aus miteinander verbundenen Stegen (3) aufgebaut ist, die untereinander verbundene kleinere Hohlräume (4) mit einer Größe im Bereich von 0,5 mm bis 6 mm einerseits, vorzugsweise von 0,5 mm bis 1 mm, und große Hohlräume (6) mit einer Größe im Bereich von 6 mm bis 20 mm andererseits, vorzugsweise von 6 mm bis 10 mm, ausbilden.
摘要:
A biodegradable osteochondral implant comprises a porous top and a porous bottom section separated by a barrier impermeable to agents that have a detrimental effect on the regeneration of cartilage. The implant or its top section is of rotationally symmetric or parallelepipedal form and comprises a resilient polymer material such as polyurethane urea. Also disclosed is a corresponding sheet material from which implants can be excised, processes of manufacture of the implant and the sheet material, and a method for implanting the osteochondral implant in a recess prepared in a load-bearing surface of a joint.
摘要:
A vertebral lift device (10) including an expandable member (4) made of a bio-compatible material and having a plurality of interconnected structural members, (22, 24) with the expandable member having a first dimension for insertion thereof into a damaged vertebral body having a damaged dimension, the interconnected structural members of the expandable member being expandable to a second dimension substantially corresponding to dimensions of the vertebral body prior to its damage, wherein the expandable member defines a void area within a periphery defined by the structural members when the expandable member is expanded to the second dimension for receiving a restoration agent; and a covering (16) configured to substantially cover the exterior of the expandable member to inhibit leakage of the restoration agent received within the void area.
摘要:
Disclosed herein are methods and devices for distracting adjacent vertebrae during surgical procedures for implanting spinal prostheses. In an exemplary embodiment, a distractor is disclosed that maintains the empty space between adjacent vertebrae following a discectomy, and that can removably mate with other surgical instruments, such as, for example, a filler bar, an implanting tool, or a funnel. In other embodiments of the present invention a distractor is disclosed having various features to assist in implanting a spinal prosthesis, such as, for example, an angled distal end and/or an expandable paddle. In another embodiment of the present invention, an articulating inserter is disclosed. Moreover, various implants and funnels are also disclosed herein.
摘要:
Resilient surgical meshes that, in some aspects, can be compressed or otherwise configured, for minimally invasive delivery in the intervertebral discs are provided. According to one or more embodiments, the surgical mesh can be robust, fatigue resistant, stable and capable of withstanding the dynamic environment generic to intervertebral discs.
