Surgical implant for restricting the relative movement of vertebrae

Surgical implant for preventing mutual contact between vertebrae during flexions of the vertebral column, characterized in that the implant includes an inter-vertebral insert insertable between the vertebral spines of at least two successive vertebrae, the insert further comprises at least one drilled hole transverse to its direction of insertion and open at two ends and retaining means defining at least one ligament for holding the insert in place in relation to the vertebral spines, the holes in the insert to permit the passage of the said ligament, there being a possibility of heightwise relative deflection of the vertebral spines.

Surgical implant for preventing mutual contact between vertebrae of a vertebral column during flexions of the vertebral column, said surgical implant comprising:

• an inter-vertebral insert means insertable between vertebral spines of successive vertebrae which form a section to be treated of the vertebral column, said inter-vertebral insert means having two end surfaces for respectively contacting the spines of the end vertebrae of said section of the vertebral column;
• and
• retaining means associated with said inter-vertebral insert means and having portions to be passed over said spines of said two end vertebrae, said portions of said retaining means being so distant from the end surfaces of said inter-vertebral insert means that the retaining means allow the vertebrae to have a relative limited movement away from each other upon forward flexion of the vertebral column.
