A staged expansion of an intervertebral scaffolding system is provided, and also include a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

Intervertebral spacer assemblies, systems, and methods thereof. A method of insertion include inserting an intervertebral spacer and plate together using an insertion tool and, upon removal of the insertion tool, the intervertebral spacer and plate are no longer considered connected/coupled and act as separate components.

Disclosed herein is an orthopedic implant device comprising a porous structure, approximating the shape of a bone, and having modulus of elasticity similar to that of said bone. In one embodiment, further disclosed herein is a method of treating injuries or diseases affecting bones or muscles comprising providing an orthopedic implant device, wherein the orthopedic implant device comprising a porous structure, approximating the shape of a bone, and having a modulus of elasticity similar to that of bone, and using the orthopedic implant device to treat injuries and diseases affecting bones and muscles in a mammal. In another embodiment, disclosed herein is a method of manufacturing an orthopedic implant device using an additive manufacturing (AM) method.

A geared cam expandable spinal implant. Rotational motion of a rotating portion is translated into linear motion of a yoke, which moves geared cams at the distal end of the implant to mate with, and walk along, teeth of corresponding racks. The walking of the gear cam teeth along the rack teeth creates a regular rate of implant expansion, reduces initial excessive expansion force applied to the implant, and provides fine adjustment of the expansion rate and force.

An expandable implant includes a body portion, a carriage portion, a deployment assembly, and an expandable portion. The deployment assembly and the expandable portion are attached to the carriage portion, and portions of the carriage portion are moveable out of and into the body portion. When the expandable implant is inserted into a disc space, the expandable portion is expandable to push the upper vertebral body and the lower vertebral body away from one another.

A method for securing a first interacting element to a second interacting element is provided. The first interacting element includes a lateral surface established by a first surface and a second surface and at least a portion of the lateral surface includes a thread receipt. The second interacting element includes a distal end and a proximal end that establishes a body therebetween. The body has a thread that is configured to at least partially engage with the thread receipt of the first interacting element. The second interacting element is then inserted at least partially through the surface of an object. The thread receipt of the first interacting element is then abutted adjacent to the thread of the second interacting element. Upon rotation of the second interacting element the thread of the second interacting element at least partially engaged with the thread receipt of the fist interacting element.

An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.

A tool for delivery and/or compaction of bone graft material includes a cannula with an inner lumen extending along a longitudinal axis from a hopper end of the cannula to a delivery tip of the cannula. A hopper with an internal volume for storing bone graft material is connected to the hopper end of the cannula with the internal volume of the hopper in communication with the inner lumen of the cannula for delivery of bone graft material from the hopper to the delivery tip of the cannula. An output shaft within the inner lumen extends along the longitudinal axis. The output shaft includes a helical screw thread extending radially outward from the output shaft toward an inner surface of the cannula. An actuator is connected to the hopper and to the output shaft to drive the output shaft rotationally relative to the hopper and to the cannula.

Deployable Euler Spiral Connectors (DESCs) are introduced as compliant deployable flexures that can span gaps between segments in a mechanism and then lay flat when under strain in a stowed position. This paper presents models of Euler spiral beams combined in series and parallel that can be used to design compact compliant mechanisms. Constraints on the flexure parameters of DESCs are also presented. Analytic models developed for the force-deflection behavior and stress were compared to finite element analysis and experimental data. A spinal implant and a linear ratcheting system are presented as illustrative applications of DESCs.

An expandable support device for tissue repair is disclosed. The device can be used to repair hard or soft tissue, such as bone or vertebral discs. The device can have multiple flat sides that remain flat during expansion. A method of repairing tissue is also disclosed. Devices and methods for adjusting (e.g., removing, repositioning, resizing) deployed orthopedic expandable support devices are also disclosed. The expandable support devices can be engaged by an engagement device. The engagement device can longitudinally expand the expandable support device. The expandable support device can be longitudinally expanded until the expandable support device is substantially in a pre-deployed configuration. The expandable support device can be then be physically translated and/or rotated.
