A method of manufacturing an orthopedic plate is disclosed. The method comprises the following steps: providing a stratum comprising a first surface for engaging bone and a second surface opposing said first surface, wherein the stratum comprises a fastener hole for receiving a fastener, wherein the fastener has a head and a shaft; providing a retaining element comprising a head and a shaft; creating a retaining hole for receiving the retaining element, wherein the retaining element extends through at least the second surface; placing the retaining element into the retaining hole to reach a fully-inserted position; cutting a portion of the head of the retaining element such that the head of the fastener can be inserted through the fastener hole and pass by the head of the retaining element to reach a fully-inserted position of the fastener. Also, an orthopedic plate made using the disclosed method is disclosed.

An ambulatory patient support mechanism, for use in hospitals and the like for assisting patients in walking along hallways, corridors, and the like. The mechanism includes a specially developed U-shaped support frame, configured to support a person in an upright position while walking. A telescoping column is vertically adjustable relative to the floor. A moveable carriage connected to the telescoping column provides horizontal movement along a suspended overhead track vertically above a given path of a hallway, corridor, or the like. A rotation mechanism allows the U-shaped frame to rotate 180° allowing patients to reverse their direction of travel along the given path. The U-shaped frame is adjustable to accommodate a wide range of body sizes. A pair of adjustable handgrips at the end of each U-frame member stabilizes the patient within the interior of the U-shaped frame. Commonly used belting and buckles secure each of the patient's upper arms to an arm restraint to aid in fall prevention should patient stumble or lose consciousness.

A spacer for inserting between vertebral members. The spacer has a non-spherical shape with an anterior section having a first shape and a posterior section having a different shape. An attachment means is positioned within the posterior section, and may include a receiver for attachment with an insertion device, and an anti-rotation mechanism for assistance in removing the spacer from the insertion device. Embodiments of using the spacer is also disclosed which may include inserting the spacer between the vertebral members in a generally posterior approach. Once inserted, the insertion device acts with the anti-rotation device to remove a connection mechanism from the receiver. The spacer remains between the vertebral members and provides relief to the patient.

An intervertebral implant system for positioning between an upper vertebra and a lower vertebra is provided. The implant system comprises an intervertebral implant and a staple. The implant comprises an inferior plate and a superior plate, while the superior plate has a vertebral surface facing the upper vertebra and the inferior plate has a vertebral surface facing the lower vertebra. There are two grooves on at least one vertebral surface extending at an angle outward from a centerline on the vertebral surface as they extend from the anterior portion of the plate toward the posterior portion of the plate. When in use, the staple is associated with the two grooves for maintaining stability of the intervertebral implant and preventing backing out of the intervertebral implant. The staple also has two arms and has a generally rectangular shape prior to use.

Systems and methods of shaping surfaces of vertebral bodies include a reference guide instrument that can be positioned relative to a disc space between vertebral bodies and referenced to the caudally located endplate of the disc space. The reference guide instrument can then be employed to guide preparation instruments to the vertebral bodies in an orientation and spacing referenced to the caudal endplate of the subject disc space to shape vertebral surfaces to receive an implant.

The present application is directed to devices and methods to space apart vertebral members over two or more spinal levels. Embodiments of the devices may include a power source, supply line, and adjustable members. The adjustable members may be positioned along two or more spinal levels. The supply line may extend between each of the members and the power source. Activation of the power source may feed power through the supply line and to each of the adjustable members. Members may move from a closed orientation towards an open orientation to space the vertebral members.

A prosthetic spinal disc system is provided. The prosthetic disc system has a nucleus component having an upper surface configured to engage a superior vertebra and a lower surface configured to engage an inferior vertebra, an anchor configured to affix to an anterior surface of at least one of the superior vertebra or the inferior vertebra, and a tether tying the nucleus component to the anchor. In such embodiments, the nucleus component further has a perimeter situated substantially between the upper surface and the lower surface of the nucleus component and the tether is at least partially situated on the perimeter of the nucleus component. In certain embodiments, the upper surface and the lower surface of the nucleus component are configured to allow for implantation of the disc system such that after a discectomy, no preparation of at least one of the superior and inferior vertebrae is necessary.

Embodiments of a drive shaft collet adapted for linking a surgical drive shaft to a surgical instrument so that the instrument may be driven by the drive shaft are disclosed. The collet includes a helically-swept cutout which forces a received shaft to be rotated into alignment during insertion. Collectively, the drive shaft collet and shaft are designed to avoid the need for multiple attempts at inserting the shaft into the collet in order to align the flats on the shaft with the flats on the collet.
