PCT No. PCT/EP94/02906 Sec. 371 Date Oct. 3, 1995 Sec. 102(e) Date Oct. 3, 1995 PCT Filed Sep. 1, 1994 PCT Pub. No. WO95/06440 PCT Pub. Date Mar. 9, 1995The clamp (1) comprises a pair of hooks (2, 3) adapted to bear on at least two cervical vertebrae (for example C1, C2) and each having a tubular portion (6, 7). The diameters of the latter are such as to permit the fitting and the sliding of one portion in the other and consequently the adjustment of the relative position of the two hooks. They are fixed in this position by a permanent deformation of the walls of the tubular portions (6, 7) by a suitable ancillary tool. The clamp provides better stability than known devices, since the two hooks (2, 3) of the clamp cannot move apart owing to their interconnection by deformation of material which clamps them in position relative to each other and avoids the use of components such as nuts and screws. Further, this clamp is small in size and is placed in position by the surgeon in a particularly simply manner. |
