  • Patent number: 10524718
    Abstract: A method is provided for detecting neural interference between a bone anchor and a neural element during or subsequent to the application of force on the bone anchor to adjust the orientation of one or more vertebral bodies relative to the spinal column. The method includes engaging at least one bone anchor to the vertebral body and applying force to the bone anchor to adjust the positioning or orientation of the vertebral body. A nerve monitoring system provides an electrical signal and is operable to detect a neural element and its proximity to the bone anchor as a function of a characteristic of the electrical signal.

  • Patent number: 9066758
    Abstract: An extender comprises an outer member including a lateral opening, first and second extensions defining first and second axial cavities, the axial cavities including a first portion, a second portion and a third portion. An inner member includes a body defining a tab, first and second arms having first and second projections. The inner member is configured for axial translation relative to the outer member between a first position, a second position and a third position. The tab is movable into at least one locking cavity of the lateral opening to fix the inner member relative to the outer member. Methods of use are disclosed.

  • Patent number: 8529604
    Abstract: A bottom-loading multi-axial bone anchor apparatus is disclosed. The apparatus includes a receiver member, a crown member, a bone anchor and a retaining member. The receiver member defines an upper opening and a lower opening, which may form part of the same opening, a channel, and a groove. The crown member and bone anchor are loaded into the lower opening of the receiver member, and the retaining member fits around the bone anchor and into the groove in the receiver member. The bone anchor is capable of multi-axial positioning with respect to the receiver member. An elongated member is placed in the channel of the receiver member, contacting the crown member, and a compression member is applied via the upper opening. The compression member presses down on the elongated member, which presses down on the crown member and locks the bone anchor between the crown member and the retaining member.

  • Publication number: 20130110123
    Abstract: Devices and methods for positioning an anchor within a patient during a surgical procedure. The devices are designed to interface with an anchor. The interface facilitates attachment of instruments to an exterior of the anchor. The devices may further be sized for use in minimally invasive surgical procedures where direct visualization and manipulation of the anchor is often impractical. The device may include first and second members that are movable relative to each other. The members include distal ends sized for insertion into a head of an anchor. The device may include a handle operatively connected to one or both members to move the members relative to each other to expand a size of the first member to engage with the head. The engagement is confined with the exterior of the head remaining exposed for attachment of an instrument to the head. One or both members may further be shaped to facilitate attachment of the instrument to the head.

  • Publication number: 20130068711
    Abstract: A surgical assembly includes an actuator. A linking member is connected to and extending from the actuator. The linking member includes a series of at least two interconnected inner links that are relatively movable such that the linking member is disposable between a flexible configuration and a rigid configuration. An arm extends from the actuator and includes a series of relatively moveable outer links that define an axial bore configured for disposal of the linking member. Each outer link defines a first mating surface and a second mating surface disposed in a configuration such that the actuator is engageable to move the linking member from the flexible configuration to the rigid configuration to selectively fix the arm in a selected orientation. Methods of use are disclosed.

  • Patent number: 8221474
    Abstract: A method for assembling a system for correcting alignment of a spinal column of a patient is provided. The method includes the steps of engaging first and second implants to a first vertebra; engaging a distal portion of respective first and second implant holders to respective ones of the first and second implants, the first and second implant holders each extending from said distal portion along a longitudinal axis to a proximal end outside the patient; engaging a transverse bridge between and to proximal ends of each of the first and second implant holders; and engaging a derotation handle to the transverse bridge at a location between the first and second implant holders and in a generally parallel orientation to a sagittal plane of the spinal column so that the transverse derotation handle extends transversely to the sagital plane.
