Abstract
The hollow tubular implant of the invention comprises an internal cavity delimited by a peripheral wall open at its first end and having a generally circular cross-section external surface. Two side surfaces are solid and top and bottom surfaces have communicating holes in them. Annular external ribs prevent retrograde movement and rotation of the implant when inserted between two adjacent vertebrae. The implant achieves good fastening together of the two vertebrae and fusion thereof by means of a bone graft inserted in the implant before fitting.
