SYSTEM AND METHODS FOR SPINAL FUSION

A system and method for spinal fusion comprising a spinal fusion implant of non-bone construction releasably coupled to an insertion instrument dimensioned to introduce the spinal fusion implant into any of a variety of spinal target sites, in particular into the thoracic region of the spine.

ORTHOPAEDIC IMPLANT WITH FIXATION FEATURE AND A METHOD OF IMPLANTING THEREOF

An orthopedic implant comprises a body having an articulating surface and a surface opposite the articulating surface. The surface opposite the articulating surface includes a fixation feature. The fixation feature is configured to have a variable width for fastening the implant to a fixation bore formed in a bone.

MODULAR INTERBODY FUSION DEVICE
20180104067 · 2018-04-19 ·

A modular anterior lumbar interbody fusion device comprises a monolithic interbody fusion cage and a modular plate resiliently attached thereto. The cage includes an open architecture with top and bottom cross members and a pair of opposing arms projecting from respective side structures of the cage to define a pocket at the cage anterior end. The modular plate is received in the pocket and attached to the cage by resilient latches. The plate lies fully within the profile of the cage with the resilient latches lying fully within the thickness of the plate. The plate provides a structure to close the anterior portion of the modular cage after introduction of bone graft material while allowing for use with integrated fixation. Attachment features between the monolithic cage and modular plate are universal allowing for selection of various modular device configurations with minimal components.

Expandable intervertebral implant

An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

ROBUST, SACROILIAC, ANCHORING IN THREE DEGREES OF FREEDOM
20240366401 · 2024-11-07 ·

An anchor has a straight centerline and straight splines extending radially while running parallel thereto. Splines extend radially from a core penetrated by a channel to fit over a K-wire guide, and axially along the length of the elongate, cylindrical core. The center line passes along the center of a lumen or channel of the hollow core, while the splines extend radially outward from, and axially along the length of the core except along a conical taper near a leading or point end of the anchor. Installation may be from a posterior access or a lateral-posterior access, each anchor fixing two bones in at least one, but usually two, degrees of freedom. Multiple anchors may fix in all six degrees of freedom (three degrees of freedom in translation along three mutually orthogonal axes, and three degrees of freedom of rotation about those same axes).

Spinal implant configured for midline insertion

The embodiments provide a spinal implant that is configured for midline insertion into a patient's intervertebral disc space. The spinal implant may have a body and the body comprises one or more apertures. The apertures receive fixation elements, 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.

Surgical impaling member
09888911 · 2018-02-13 · ·

An implant for orthopedic surgery includes an impaling member (101,102), which is separable into portions (102a, 102b) for impaling and attaching to tissue, for example, bone. Once the portions (102a, 102b) of the impaling member (101,102) are separated and attached to the requisite tissue, they may accommodate stabilizing members for fixation, or other instrumentation for procedures such as fusion.
