Abstract: An insertion instrument for expandable spinal implants includes an elongate member, a shuttle, and a worm gear. The elongate member includes a handle portion of a proximal end and an end effector on a distal end, wherein the end effector is configured to be releasably engaged to an expandable spinal implant. The shuttle is slidably disposed within a cavity defined within the end effector and includes a wedged shaped distal end configured to engage an expandable spinal implant. The worm gear is rotatably disposed within the cavity defined in the end effector and is in mechanical communication with the shuttle, such that rotation of the worm gear effectuates movement of the shuttle. Distal movement of the shuttle effectuates articulation of an expandable spinal implant. A method of performing surgery is also disclosed.

Abstract: An interbody spacer is provided including a body portion defining a longitudinal axis. The body portion includes a distal end portion, a proximal end portion, opposed side surfaces that extend between the distal and proximal end portions, and top and bottom surfaces configured and adapted to engage vertebral bodies. The interbody spacer includes first orifices defined through the top surface. The first orifices include orifices having first and second cross-sectional configurations and the first orifices are arranged in rows extending along the longitudinal axis.

Abstract: A bone screw for attaching a spinal prosthetic or bone plate to bone includes a tubular body having open proximal and distal ends. The open proximal and distal ends define a passageway therethrough. A shaft is insertable into the passageway and includes a distal tip that extends beyond the open distal end. The shaft is insertable through a lumen of a head of the bone screw. A gap is defined between a distal surface of the head and a proximal end of the tubular body. The shaft is rotationally fixed with the tubular body and the head. The head is repositionable with respect to the shaft such that an acute angle is defined between the head and a longitudinal axis of the shaft.
