An implant and method for posterior sacroiliac fusion having a plate for placement across the posterior surface of the sacroiliac joint, a transverse pin to slide through the plate and transverse the joint as well as provide an aperture to receive bone graft, and a sacral screw to be inserted through the plate.

An expandable vertebral body implant, and methods of assembly and using the implant. The vertebral body implant includes a body with a first end and a second end, a rotating member rotatably coupled to the first end of the body, wherein an end includes a plurality of first notches inset into the rotating member, an extension member moveably coupled to the rotating member, and a locking member positioned on an interior of the body. Methods for assembling and using the vertebral body implant are also disclosed.

An implant preshaped before placement anteriorly between a superior endplate and an inferior endplate within a void created by a transcorporeal procedure in a vertebra, the implant having no circular cross-sectional dimension.

The present disclosure relates to an orthopedic implant, wherein the implant is a 3D printed part and comprises at least one first portion and at least one second portion, the first portion forming a support structure and the second portion being at least partially made of a biodegradable material.

The present disclosure further relates to a method of manufacturing an orthopedic implant.

A bone fusion device provides stability to bones during a bone fusion period. The bones include, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable tabs attached to the bone fusion device by associated rotating means. The bone fusion device is preferably inserted by using an arthroscopic surgical procedure. During arthroscopic insertion of the device, the tabs are pre-configured for compactness. In this compact configuration, the tabs are preferably deposed along and/or within an exterior surface of the bone fusion device. After the bone fusion device has been positioned between the bones, one or more tab(s) are extended. In the preferred embodiment, the position of each tab is related to a positioning element and extending blocks. Typically, the tabs advantageously position and brace the bone fusion device in the confined space between the bones until the bones have fused.

The biocompatible lattice structures and implants disclosed herein have an increased or optimized lucency, even when constructed from a metallic material. The lattice structures can also provide an increased or optimized lucency in a material that is not generally considered to be radiolucent. Lucency can include disparity, maximum variation in lucency properties across a structure, or dispersion, minimum variation in lucency properties across a structure. The implants and lattice structures disclosed herein may be optimized for disparity or dispersion in any desired direction. A desired direction with respect to lucency can include the anticipated x-ray viewing direction of an implant in the expected implantation orientation.

A vertebral body system and method having a polyaxial fastener receiving member, adjustable width plates and a pedicle screw having a pedicle threaded portion and a threaded portion for fastening to the vertebral body.

A spinal implant includes a first member that is curved along an axis between opposite ends. The first member defines a bore and a first thread. A second member is positioned in the bore and is curved between opposite ends. The second member includes a second thread engaged with the first thread. The second thread includes a series of gear teeth. A third member is positioned in the bore and is curved between opposite ends and includes opposite ends. A driver includes a gear configured to engage the gear teeth such that rotation of the driver relative to the first member and the second member rotates the second member relative to the first member to translate the second member relative to the first member along the axis. Systems and methods are disclosed.

An interbody fusion cage having upper and lower canals for receiving the heads of bone screws that have been pre-installed in opposing vertebral body endplates. The proximal wall of the cage preferably has a vertical slot that communicates with each canal and is adapted to allow access by a screwdriver and tightening of the screws.

A method is disclosed for introducing a spinal disc implant into an intervertebral space of a subject. The subject is placed in a lateral position, and the anterior face of the spinal disc intervertebral space is accessed, between the L5 and S1 vertebrae, from an anterior and lateral retroperitoneal approach. An operative corridor to the anterior face of the spinal disc space is established by introducing a retractor instrument anterolaterally to the spinal disc space between the anterior superior iliac spine and the anterior inferior iliac spine. The damaged spinal disc contents are removed from the intervertebral space through the operative corridor, and the implant is advanced into the intervertebral space at an oblique angle and pivoted to position the implant substantially laterally within the intervertebral space. Elongated retractor and insertion instruments, as well as a modified disc implant, are also disclosed for carrying out the method.
