  • Publication number: 20130338717
    Abstract: Methods for installing bone anchors, such as pedicle screws or other surgical screws. In some implementations, the surgical screw may be coupled with a connection member, such as a tulip assembly, configured to couple the surgical screw with a stabilization member, such as a spinal fixation rod. The connection member may be initially coupled with the surgical screw in a polyaxial configuration, after which the connection member may be secured to the surgical screw in a monoaxial configuration. The stabilization member may then be coupled and secured with the connection member such that the stabilization member cannot move relative to the connection member. In some implementations, the stabilization member may be locked or secured to the connection member after the connection member has been secured to the surgical screw in a monoaxial configuration.

  • Publication number: 20130253596
    Abstract: Pedicle screw assemblies and related bone screws. In some embodiments, the bone screw may comprise a head portion and an axial shaft. The axial shaft may comprise a threaded portion comprising a triple lead thread disposed about the axial shaft. The axial shaft may further comprise a tapering portion and a non-tapering portion. The tapering portion may comprise multiple tapering portions tapering at differing rates, and may be positioned adjacent to a tip of the axial shaft. Each of the three leads may extend coextensively along at least a majority of the length of the axial shaft, the threaded portion, the tapering portion, and/or the non-tapering portion.

  • Patent number: 8512382
    Abstract: The present invention relates to an alternatively monoaxial and polyaxial pedicle or other similar surgical screw that can be used in a polyaxial manner and then locked or otherwise secured at a desired angle or orientation, i.e. used in a monoaxial manner, prior to engaging a rod or other similar stabilization member with the pedicle or other similar surgical screw. In other words, the present invention provides a pedicle or other similar surgical screw that can be selectively used in either a monoaxial or polyaxial configuration, as is desirable in a particular application or at a particular point of a given surgical procedure.

  • Patent number: 8382811
    Abstract: A pedicle screw assembly, including: a bone screw having a head portion and a thread portion, wherein the thread portion includes an axial shaft and a triple lead thread disposed about the axial shaft; and a rod retention member selectively coupled to the head portion of the bone screw. Optionally, the triple lead thread includes leads that originate at different points along the axial shaft. Optionally, the triple lead thread includes leads that terminate at different points along the axial shaft. Optionally, the axial shaft includes a first tapering portion proximate a tip of the axial shaft. Optionally, the axial shaft includes a second tapering portion proximate the tip of the axial shaft. Preferably, the second tapering portion tapers more steeply than the first tapering portion. Optionally, the axial shaft includes a reduced diameter portion proximate the head portion. Optionally, the axial shaft includes one or more tapering portions proximate the head portion.

  • Publication number: 20070093363
    Abstract: In an illustrative embodiment of the invention, an exercise device comprises a support structure comprising a support member and a support arm having an upper support arm portion and a lower support arm portion. The support arm is mounted to the support member by a pivot assembly comprising a longitudinal pivot control mechanism and a lateral pivot control mechanism. The longitudinal pivot control mechanism is configured to allow the support arm to be selectively positioned at a first angular orientation in a longitudinal plane and the lateral pivot control mechanism is configured to allow the support arm to be selectively positioned at a second angular orientation in a lateral plane orthogonal to the longitudinal plane. The exercise device further comprises a yoke pivotably attached to the upper support arm by a yoke attachment member for rotation about a yoke rotation axis.

  • Publication number: 20060003875
    Abstract: An exercise device is provided that comprises a support arm having an upper support arm member defining an upper support arm axis and a lower support arm member defining a lower support arm axis. The exercise device further comprises a support structure to which the support arm is pivotably attached by a longitudinal pivot mechanism and a lateral pivot mechanism. The longitudinal pivot mechanism is adapted so that the support arm may be selectively rotated about a longitudinal pivot in a pitch plane that includes the upper support arm axis. The longitudinal pivot mechanism is also adapted so that the support arm may be selectively locked at a selected pitch rotational position. The lateral pivot mechanism is adapted so that the support arm may be selectively rotated about a lateral pivot point in a vertical plane that is orthogonal to the pitch plane. The lateral pivot mechanism is also adapted so that the support arm may be selectively locked at a selected lateral rotational position.
