    Abstract: An orthopedic device including a longitudinal plate assembly having an adjustable length and two ends. Each of the ends includes a feature that can be used to couple the end to a body structure, such as, for example, a vertebral bone. Preferably, the assembly includes two longitudinal plates that can translate longitudinally with respect to one another through a plurality of positions and be secured with respect to one another at one of the positions, thereby enabling the length of the assembly to be adjusted. Inasmuch as the length of the plate assembly can be adjusted, the surgeon can set the length to the most clinically appropriate length for effective coupling of the plate assembly to the body structure.

    Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a cross bar mounting element having a socket into which the head of the screw is initially polyaxially nested. The cross bar mounting element further includes a vertical split which permits the socket to be expanded or compressed via the application of a corresponding force directed at the split. The cross bar mounting element further includes a pair of upwardly extending members which define a trough into which a cross bar element is positioned. The cross bar element includes features which permit the secure fixation of a rod thereto, as well as a selectively slideable element, such as a nut, which may be tightened to apply the compressive force necessary to compress the interior volume onto the head of the screw, thus locking the assembly in place.

    Abstract: A rod, screw, and staple assembly for use in conjunction with anterior or lateral spinal rod implant apparatus includes a screw having a vertebral body screw which has a shaft which is insertable into a vertebral bone and a head portion which includes a rod receiving channel and a radially extending flange. The vertebral body staple includes a flat portion which has a hole through it. The hole has a rim which is upwardly extending and a concave recess formed in the underside of the flat portion around the hole. The staple also includes several barbs which independently hold the staple to the bone surface to which it is to be affixed. The screw is first inserted into the vertebral bone, and then the staple is mounted over the head portion of the screw, such that the head extends above the annular rim. The rod is then inserted into the rod receiving channel and seats against the uppermost surface of the annular rim. The application of a top locking nut onto the head of the screw causes the rod to compress against the staple, the barbs of which are driven into the vertebral bone, and the staple is further compression locked to the screw.

    Abstract: A curette having a variably angled handle includes a curette member which has a disc shaped end. The disc shaped end has a hole through its center and a series of discrete angular graduations on its edge. The disc shaped end is retained via a pin in a recess in the proximal end of a handle. The handle includes an axial bore through which a shaft extends into selective contact with the graduations on the disc shaped end of the curette member. The curette may be angularly positioned relative to the handle if the shaft is selectively disengaged from its contact with the graduations of the disc shaped end of the curette member, but not once the shaft has engaged the graduations. The shaft may be selectively engaged by a variety of different ways, including spring biasing, threading and having a selectively extendable handle.

    Abstract: A modular polyaxial pedicle screw and orthopaedic rod implant device including same includes a shaft portion, a cuff, a stem portion, and a rod coupling sub-assembly. The shaft portion is designed to be inserted into the pedicle, has a recess formed in its top, and includes a threading formed on the exterior surface around the recess. The stem portion is a threaded post having an enlarged ball formed at the base thereof, the ball being ideally suited to polyaxially rotate within the recess of the shaft. The cuff is a cylindrical element designed to seat around the interface of the ball portion of the stem and the recess of the shaft, initially so that the stem and shaft may polyaxially rotate relative to one another, and subsequently to hold the stem and shaft in final securement. The rod coupling sub-assembly consists of a rod coupling element which is mountable on the post portion of the stem, and a top locking nut which secures the rod coupling element to the post between the nut and the cuff. Spacer elements may be utilized which are positioned on the post between the cuff and the rod coupling element to permit axial variability on the stem in addition to the angular variability inherent in the shaft and stem interface.

    Abstract: A polyaxial colletted locking mechanism for use with orthopedic apparatus includes a screw, hook, or other orthopaedic implant element having a curvate head and a coupling element. The coupling element has a tapered and colletted portion having an interior chamber in which the curvate head is initially polyaxially disposed. A locking collar is disposed around the tapered and colletted portion such that translation thereof in the direction of the expanding taper causes the interior volume to contract onto the curvate head and lock it therein. The coupling element generally also includes a rod receiving recess in either the side or top thereof for for receiving a rod of the total implant apparatus. The locking collar may be caused to translate into its locking position by a mutual threading on the tapered portion and the collar, or by pressure applied to it by a separate element which locks the rod in the channel.
