SURGICAL INSTRUMENTS AND METHODS
A cement restrictor inserter instrument (130) comprises an inserter (131) having a handle (132) at a proximal end, a cement restrictor attachment formation (137) at a distal end for releasably attaching a cement restrictor (150), a shaft (136) extending from the proximal end to the distal end and a stop (138) on the shaft and between the proximal end and the distal end; and a body (140) having a shape corresponding to the shape of an orthopaedic prosthetic implant, a spacer (142), a visible depth guide feature (190) and a releasable attachment mechanism by which the body is releasably attachable to the shaft, and wherein the spacer is configured to position the visible depth guide feature at a fixed position relative to the inserter when the spacer abuts the stop corresponding to a target cement restrictor position when the visible depth guide feature is aligned with a feature of a bone of a patient in which the cement restrictor is to be inserted.
SPINAL FUSION SPACER WITH INTEGRATED GRAFT DELIVERY
A spinal fusion implant that is inserted into a cleared disc space during a spinal fusion surgical procedure using an insertion tool, where the insertion tool also provides delivery of bone graft material once the implant is in the disc space. The implant includes a perimeter portion having a front wall, a back wall and opposing side walls defining an enclosure, where the perimeter portion is open in an up and down direction, and where the front wall includes an opening extending therethrough to the enclosure and being configured to accept the bone graft material to fill the enclosure.
IMPLANT WITH ABILITY TO CAPTURE EXTRAVASATING FIXATION MEDIUM
A surgical implant with recesses adapted to capture fixation medium that extravasates during implantation. The implant includes an elongated stem having a distal tip configured for insertion into an implant receiving area of a patient. A collar having recesses for capturing extravasating fixation medium is attached on the stem. The collar can be fixed to the stem by a separable collar-engagement feature or the collar can be fixed to the stem via structures on the stem.
Bioabsorbable anchoring member for insertion into a vertebral body
Some embodiments of the invention provide an apparatus that (1) delivers a fusion member between two vertebral bodies after at least a portion of the fibrocartilaginous disc between the vertebral bodies has been removed, and (2) affixes the fusion member to the vertebral bodies. In some embodiments, the apparatus includes (1) a fusion member that is delivered and positioned between the vertebral bodies, (2) a delivery mechanism that delivers and positions the fusion member between the vertebral bodies, and (3) an anchoring member that affixes the fusion member to the vertebral bodies.
Orthopedic augments having recessed pockets
Systems, devices, and methods are described for providing orthopedic augments having recessed pockets that receive a fixation material. The orthopedic augments include an outer surface that interfaces with a patient's tissue or bone, and an inner surface that interfaces with an implant, the inner surface comprising a recessed pocket configured to receive a fixation material, a rim around at least a portion of the recessed pocket, and a port in the rim, wherein the recessed pocket extends along the inner surface in at least a direction laterally from the port.
BALLOON, MEDICAL DEVICE AND MEDICAL PROCEDURE FOR DISCOPLASTY
A balloon, a medical device, and a medical procedure for discoplasty are disclosed. The balloon has a compressed, collapsed or folded balloon body containing a first chamber for, in use, receiving injected bone cement. With the bone cement filled and cured therein, the balloon acts as a support in tissue of an intervertebral disc while preventing the bone cement from leakage and dispersion. The deployed balloon body defines a second chamber running therethrough. The second chamber is configured to receive a material or cells that activate osteogenesis and/or osteo-induction, so that the material or cells injected into the second chamber through a second sprue form osteocytes or induce human spontaneous local cellular differentiation to in turn form osteocytes in the cavity of the intervertebral disc and connect vertebrae above and below the intervertebral disc, thereby securely anchoring the balloon within the intervertebral space.
ORTHOPEDIC AUGMENTS HAVING RECESSED POCKETS
Systems, devices, and methods for providing orthopedic augments having recessed pockets that receive a fixation material. The orthopedic augments include an outer surface that interfaces with a patient's tissue or bone, an inner surface that interfaces with an implant and having a recessed pocket configured to receive a fixation material, a rim around at least a portion of the recessed pocket, and a port in the rim, wherein the recessed pocket extends along the inner surface in at least a lateral direction from the port.
AUGMENTATION DEVICE
The invention relates to an augmentation device comprising an annular cone surrounding a channel which extends axially along a longitudinal axis of the augmentation device from a proximal cone end to a distal cone end, wherein an outer diameter of the cone decreases from the proximal cone end in the direction of the distal cone end.
Rotatable intervertebral spacing implant
An intervertebral spacing implant, including: a seat having an interior surface and an exterior surface; branches having an anterior end and a posterior end, the anterior end of the branches coupled to the seat and extending in a direction away from the seat, each of the branches having an interior surface and an exterior surface opposite the interior surface, the seat and the branches forming a cage, the exterior surface of the seat and the exterior surface of the branches defining an internal volume of the cage, the cage including fenestrations; a spacer configured to fit within the cage and move in the direction away from the seat and toward the posterior end of the plurality of branches, the spacer and the cage configured such that the branches will move from an unexpanded position to an expanded position when the spacer is urged in the direction away from the seat.
Balloon, medical device and medical procedure for discoplasty
A balloon, a medical device, and a medical procedure for discoplasty are disclosed. The balloon has a compressed, collapsed or folded balloon body containing a first chamber for, in use, receiving injected bone cement. With the bone cement filled and cured therein, the balloon acts as a support in tissue of an intervertebral disc while preventing the bone cement from leakage and dispersion. The deployed balloon body defines a second chamber running therethrough. The second chamber is configured to receive a material or cells that activate osteogenesis and/or osteo-induction, so that the material or cells injected into the second chamber through a second sprue form osteocytes or induce human spontaneous local cellular differentiation to in turn form osteocytes in the cavity of the intervertebral disc and connect vertebrae above and below the intervertebral disc, thereby securely anchoring the balloon within the intervertebral space.
