    Abstract: A bone plate and system is provided. The bone fixation plate conforms to the contour of an irregularly shaped bone and eliminates the need for pre-bending or intraoperative bending of the plate. The bone plate is applied to the bone in a generally flat condition and the process of installing and tightening the bone screws in the prescribed order serves to contour the plate to the underlying bone while providing sufficient strength to effect bone healing. The geometry of the plate allows the plate to follow the contour of an irregularly shaped bone, preventing prominence and patient palpability and streamlining the surgical procedure.

    Abstract: Strip fasteners and cranial plugs for use in reattaching a skull flap removed during brain surgery and methods of using the same. The strip fasteners are flexible and can be shaped to follow the perimeter contour of the skull flap. The cranial plugs can be used to reattach the skull flap or they can be installed after the skull flap is reattached using the strip fasteners. In some embodiments, the cranial plug(s) and strip fasteners can be installed at the same time. The strip fasteners and cranial plugs are designed to encourage bone growth and healing of the skull flap and they can be used to deliver medication and bone growth enhancement compositions to the surgical site.

    Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a two-piece interlocking coupling element which mounts about the curvate head, and a rod receiving cylindrical body member having a tapered socket into which both the screw and the interlocking coupling element are securely nested. The interlocking coupling element includes a socket portion which is slotted and tapered so that when it is radially compressed by being driven downwardly into the tapered socket in the cylindrical body it crush locks to the screw. The securing of the rod in the body member provides the necessary downward force onto the socket portion through a contact force on the top of the cap portion. Prior to the rod being inserted, therefore, the screw head remains polyaxially free with respect to the coupling element and the body. In a preferred embodiment, the cap portion and the socket portion are formed and coupled in such a way that when the cap portion is compressed toward the socket portion, there is an additional inward radial force applied by the cap portion to the socket portion, thereby enhancing the total locking force onto the head of the screw.

    Abstract: An intervertebral spacer has curvate upper and lower rough surfaces that stimulate bone growth and is formed from a porous material that facilitates bone growth thereinto. The spacer has a plurality of smooth linear grooves to facilitate insertion of the spacer into an intervertebral space using a spacer insertion tool that has a scissor-style body. Each of the insertion tool's arm's heads has an inner surface having a pair of smoothed linear protrusions that fit within the linear grooves of the spacer when the heads are closed about the spacer. When the spacer is held, spaces are present between the spacer's rough surfaces and the heads' inner surfaces so that when the protrusions are longitudinally slid from the grooves to leave the spacer in the intervertebral spacer, the rough surfaces are not disturbed.
