Abstract
A device for reconstructing a spinous process, the device comprising a main portion having at least a first engaging hole; one fixing bar transversely insertable into the engaging hole; and said main portion having at least one through-seat for inserting ligaments to be reconstructed. Other aspects are disclosed and claimed.
Claims16
A device for reconstructing a spinous process of a vertebrae, comprising:
- a main portion having a first surface and a second surface, the first surface and the second surface being opposite and spaced apart from each other, the main portion defining at least one engaging hole and at least one through-seat, wherein the engaging hole and the through-seat extend through the first and second surfaces, and the at least one through-seat is configured for the insertion of ligaments to be reconstructed;
- one fixing bar transversely insertable into the engaging hole,
- wherein said device is fixable to the vertebrae, so that said main portion is configured for replacing the spinous process of the vertebrae to be reconstructed,
- wherein said fixing bar is realized in a single body, and
- wherein said first and second surfaces of the main portion are tapered and each surface comprises a widened portion and a narrow portion positioned at the opposite end of the main portion with respect to the widened portion, wherein the widened portion defines the engaging hole for the fixing bar.

A spinal fixing equipment, comprising:
- a main portion having a first surface and a second surface, the first surface and the second surface being opposite and spaced apart from each other, the main portion defining at least one engaging hole and at least one through-seat for inserting ligaments to be reconstructed, wherein the engaging hole and the through-seat extend through the first and second surfaces;
- one transverse fixing bar transversely insertable into the engaging hole;
- a pair of side longitudinal bars suitable for being arranged in a sagittal direction along the sides of the spinous processes of the cervical and/or spinal vertebrae;
- and
- a connection element between each of said longitudinal bars and said transverse fixing bar.
