摘要： An implantable spinous process fixation device includes an elongated component, top and bottom pivoting wing components, arranged opposite and parallel to the elongated component and separated from it by a spacer. First and second spinous processes of first and second adjacent vertebras are clamped between a top portion of the elongated component and the top pivoting wing and between a bottom portion of the elongated component and the bottom pivoting wing, respectively, by pivoting the top and bottom pivoting wings toward the top and bottom portions of the elongated component. The clamping of the spinous processes stabilizes the positions of the adjacent vertebras and prevents them from moving relative to each other.

摘要： A bone screw assembly includes a tulip-shaped seat, a bone fixation device, a ring-shaped washer, a rod and a cap. The tulip-shaped seat comprises a through opening dimensioned to receive the bone fixation device and a horizontal channel dimensioned to receive the rod. The washer is placed into the seat on top of the bone fixation device head and comprises first and second side tabs and a first pair of upward extending projections separated by a first gap and a second pair of upward extending projections separated by a second gap. The side tabs interface with a groove formed in the bottom portion of the seat. The rod is placed within the channel and positioned within a groove formed on the top surface of the washer. The cap includes first and second projections extending downward from its bottom surface and each of the first and second downward projections comprises first and second sidewise extending ridges. The first ridges of the first and second projections are aligned and placed within the first and second gaps of the washer, respectively, and interface with a first groove formed on the side portion of the seat and the second ridges interface with a second groove on the side portion of the seat when the cap is rotate.

摘要： A spinal fixation element includes a screw and a washer. The screw comprises an elongated body of a first diameter and the body includes a threaded portion at a distal end and a semispherical head of a second diameter at a proximal end. The second diameter is larger than the first diameter. The washer comprises a semispherical through opening of a third diameter at the top, of a fourth diameter in the middle and of a fifth diameter at the bottom. The third diameter is slightly smaller than the second diameter, the fourth diameter is slightly larger than the second diameter and the fifth diameter is smaller than the second diameter. The washer surrounds the semispherical head, is non-removably attached to the semispherical head and is rotatable and positionable at an angle relative to the elongated body.

摘要： A spinal screw assembly includes a bone-anchoring member, a washer, and a seat. The bone-anchoring member includes a main shaft, a washer head, and a spherical head. The spherical head extends upward from the top end of the main shaft and the washer head extends laterally from a location of the main shaft between the main shaft's top end and bottom end. The washer is polyaxially rotatable and positionable around the washer head and is configured to be placed at a first angle relative to the main shaft. The seat is polyaxially rotatable and positionable around the spherical head independent from the washer and is configured to be placed at a second angle relative to the main shaft, wherein the second angle is independent from the first angle.

摘要： A method for spinal rod insertion includes providing a U-shaped hook tool comprising first and second legs, and inserting the first leg into a first location of a first vertebra and then pushing the hook tool along an arc-shaped path until the first leg exits through a second location of an adjacent second vertebra. Next, providing a spinal stabilization rod and a folded flexible wire comprising first and second open ends at the front end and a closed loop end. The closed loop end is attached to a first end of the spinal stabilization rod and the first and second open ends of the folded flexible wire are inserted into an open end of the second leg of the hook, and the folded flexible wire is threaded through the U-shaped hook and the first and second open ends of the flexible wire exit through an open end of the first leg.
