Intervertebral spacer

Disclosed is an assembly and method for implant installation between adjacent vertebral bodies of a patient. The implant has a support body and a rotatable insert therein and the support body is curved for installation between adjacent vertebral bodies transforaminally. An installation instrument is also disclosed for removable attachment to implant and engagement with the rotatable insert to selectively permit rotation between the insert and the support body. The installation instrument extends along a longitudinal tool axis and when the installation instrument is in a first position the insert is rotationally fixed with respect to the support body and when the installation instrument is in a second position the support body may rotate with respect to the insert.

ARTHRODESIS IMPLANT AND INSTRUMENT FOR GRIPPING SUCH AN IMPLANT

The invention concerns an arthrodesis implant (1) allowing promoting the bone fusion of two bones, said implant (1) comprising: a rigid and non-deformable anchoring body (4), designed to ensure the anchoring of the implant (1) in a first bone (2), a deformable portion (5) designed to ensure the anchoring of the implant (1) in a second bone, said deformable portion (5) comprising at least two anchoring arms (9, 10) which protrude beyond the anchoring body (4) from the base end (7) of the latter, the anchoring arms (9, 10) being separated from each other by a free space (E) so as to be able to be brought closer to each other by deformation of said anchoring arms under the action of the second bone. and being characterized in that at least one of the anchoring arms (9, 10) is provided with a longitudinal reinforcing fin protruding beyond the anchoring arm (9, 10) from a lateral side (20) of the latter. Osteosynthesis surgical implants.

IMPLANT PLACEMENT

Embodiments of the present invention relate generally to implant placement into bone. More specifically, embodiments of the invention relate to implant placement across the sacro-iliac joint. Placement can be facilitated using various CT imaging views that allow the implants to be placed in bone associated with articular cartilage.

Orthopaedic implant with porous structural member

A tool for use with an orthopaedic implant includes: a tubular assembly including a tubular passage having a first end and a second end, the first end including a means for attachment to an implant body; a plug; and a plunger coupled to the plug. The tubular passage is configured to receive, via the second end, a material agent and the plunger coupled to the plug. The plunger is configured to slide through the tubular passage for expelling the material agent from the tubular passage into a load bearing member via the at least one first opening. The plunger is configured to rotate within the tubular passage for coupling the plug with the first opening to seal the first opening against expulsion of the material agent from the load bearing member via the first opening.

Syndesmosis treatment construct

An apparatus and method are provided for a syndesmosis treatment construct configured to be placed into a cinched configuration that presses a first bone against a second bone. The syndesmosis treatment construct comprises a proximal fixator to contact the first bone and a distal fixator to contact the second bone. A first suture and a second suture are parallelly looped through the proximal fixator and oppositely looped through the distal fixator. Distal ends of the first and second sutures are fixated within a washer disposed between the proximal fixator and the first bone. Proximal ends of the first and second sutures are passed through openings in the washer and through the proximal fixator. Pulling of the proximal ends by a practitioner places the syndesmosis treatment construct into a cinched configuration. Any of various suitable suture knots may be formed so as to fixate the cinched configuration.

MATING INSTRUMENT SET FOR FUSING A SACROILIAC JOINT
20220031461 · 2022-02-03 ·

An instrument set for installing a fusion implant into the sacroiliac joint (“SI Joint”). The apparatus comprises a working channel having an alignment means, a joint locator having a first keying means, an abrading device having a second keying means, and an implant inserter having a third keying means. The first, second, and third, keying means mate with the alignment means when the joint locator, abrading device, and implant inserter, respectively, are inserted into the working channel.

FIXATION SCREW & METHOD
20220031365 · 2022-02-03 ·

The invention discloses an improved wedging cage within the sacroiliac (SI) joint and fixation screw(s). The wedging cage is adapted to be positioned between the sacrum and the lilac bone (e.g., the sacroiliac joint), and the wedging cage is effective to receive one or more fixation or axial screws to fasten the wedging cage and secure the wedging cage to the adjacent pelvic bones to provide a combination effect of fusion and/or fixation. Accordingly, the improved fixation screw assemblies promote flexibility and adaptability due to the adjustable head being movable to a locked and unlocked position relative to the screw body when implanted onto a substrate.

Biodegradable implant for intertransverse process fusion

A biodegradable implant for use in intertransverse process spinal fusion having an absorbable matrix having a bone generating material disposed therein. A molded biodegradable case being made of bioabsorbable polymer can at least partially surround the absorbable matrix to carry a substantial portion of compression force relative to said absorbable matrix.

Tapered, cylindrical cruciform hammer toe implant and method

An implant is disclosed including an elongated threaded portion and a blade portion extending from the elongated threaded portion. The blade portion has a substantially cylindrical cross-sectional geometry and a taper defined by a plurality of blades.

Titanium plasma coated medical grade thermoplastic or polymer proximal and distal interphalangeal toe implant

A medical grade thermoplastic or polymer implant with an osteoconductive coating is provided, specifically for corrections of the distal and proximal interphalangeal toe joints of the foot. The implant can be either straight or angled, and can be either solid or cannulated for insertion. The implant is sized and shaped depending on the specific anatomy and desired correction. End portions of the implant may be coated with an osteoconductive coating that promotes bone growth, but may reduce radiolucency. Thus, a central portion of the implant may remain uncoated to increase radiolucency of the implant at the region where two bones come together.
