  • Publication number: 20200138494
    Abstract: A bone screw for attaching a spinal prosthetic or bone plate to bone includes a tubular body having open proximal and distal ends. The open proximal and distal ends define a passageway therethrough. A shaft is insertable into the passageway and includes a distal tip that extends beyond the open distal end. The shaft is insertable through a lumen of a head of the bone screw. A gap is defined between a distal surface of the head and a proximal end of the tubular body. The shaft is rotationally fixed with the tubular body and the head. The head is repositionable with respect to the shaft such that an acute angle is defined between the head and a longitudinal axis of the shaft.

  • Publication number: 20200093610
    Abstract: A spinal implant configured for positioning within a space between adjacent vertebral bodies includes first and second bone screws and a body. The body includes a back surface having first and second openings for receiving the first and second screws. The first and second openings are configured for orientation towards opposing vertebral bodies. The body further includes first and second side surfaces extending from opposing ends of the back surface and first and second end surfaces extending from respective first and second side surfaces, wherein the ends of the first and second end surfaces meet and define an atraumatic nose. A first angle is formed between the first side surface and the first end surface that is different than a second angle that is formed between the second side surface and the first end surface. A method using same is also disclosed.

  • Publication number: 20190274845
    Abstract: A driving instrument for adjusting a spinal implant includes an outer shaft having a distal end configured to actuate a proximal adjustment assembly of a spinal implant, and an inner shaft having a distal end configured to actuate a distal adjustment assembly of the spinal implant. The inner shaft is disposed within the outer shaft, with a proximal end of the inner shaft extending proximally from the outer shaft. The proximal end is configured to be rotated such that rotation of the inner shaft results in simultaneous rotation of the inner and outer shafts, with rotation of the outer shaft ceasing at a first value of resistance associated with the proximal adjustment assembly and rotation of the inner shaft ceasing at a second value of resistance associated with the distal adjustment assembly such that cessation of rotation of the inner shaft is independent from cessation of rotation of the outer shaft.

  • Patent number: 9498350
    Abstract: An insertion device includes a first engagement arm having a first body portion and a first proximal extension, a second engagement arm including a second body portion and a second proximal extension, and an adjustment mechanism. The second proximal extension is disposed about the first proximal extension and is slidable therealong to vary a spacing between the first and second engagement arms. The adjustment mechanism includes an adjustment screw rotatably coupled to the first proximal extension and an adjustment cylinder coupled to the second proximal extension. The adjustment cylinder is configured to receive the adjustment screw in threaded engagement therewith such that rotation of the adjustment screw relative to the adjustment cylinder urges the second proximal extension to translate along the first proximal extension to vary the spacing between the first and second engagement arms.
