Abstract
Fixation devices for stabilization and fusion of the lamina after laminoplasty are described. The device comprises of a plate with several holes that receive bone fasteners. The plate is curved at the ends to contour to the vertebral structure and has a spacer in the middle to engage the displaced lamina in a fixed position. Several fixation devices for dynamically stabilizing the lamina after either the open door, double door or expansive laminoplasty technique are provided.
Claims26
A bone fixation device for the lamina of the spine after laminoplasty comprising of:
- i) an elongated plate with curvature at the ends of the longitudinal axis, downward for fixation to a lamina and upward for fixation to a facet by means of a screw through bone screw receiving holes at each end of the said plate, and ii) a rectangular shaped spacer in the middle of the plate with ends which engage and maintain the displaced edges of the lamina in a fixed position
A bone fixation device for the lamina of the spine after laminoplasty comprising of:
- i) an elongated plate with bone screw receiving holes at the ends wherein said plate has a U-shape to allow for fixation to the lamina via screws, and ii) a spacer in the middle of the plate which engages and maintains the displaced edges of both lamina in a fixed position
A bone fixation device for the lamina of the spine after laminoplasty comprising of:
- i) an elongated plate with bone screw receiving holes at the ends wherein said plate has a U-shape in the middle and an inverse L-shaped curvature at the ends on both sides to allow for fixation to the facets via screws, and ii) a spacer in the middle of the plate which engages and maintains the displaced edges of the lamina in a fixed position
