Abstract
Methods and devices that utilize segmental fixation between several adjacent vertebrae, thus allowing each vertebrae to be adjusted independently, are provided. In general, the device includes a spinal anchoring element that is adapted to seat at least one spinal fixation element, and a closure mechanism that is adapted to mate to the spinal anchoring element to lock the at least one spinal fixation element in a fixed position relative to the spinal anchoring element.
Claims24
A device for treating spinal deformities, comprising:
- a spinal anchoring element configured to seat first and second spinal fixation elements at a distance spaced apart from one another;
- a bone screw configured to mate to bone, the bone screw being configured to mate the spinal anchoring element to the bone without contacting the first and second spinal fixation elements when the first and second spinal fixation elements are seated in the spinal anchoring element;
- a closure mechanism configured to mate to the spinal anchoring element, the closure mechanism being configured to directly engage and lock each of the first and second spinal fixation elements in a fixed position relative to the spinal anchoring element;
- and
- a unitary locking mechanism configured to be seated in a bore formed in the spinal anchoring element and to mate the closure mechanism to the spinal anchoring element.
