Lockable connecting device for spiral osteosynthesis anchoring elements.

摘要

- The invention relates to a lockable connection device for two spinal osteosynthesis anchoring elements (3), the said anchoring elements (3) comprising an osseous fastening part (4) formed by a screw, by a curved plate or the like and a body for fastening a solid-attachment rod formed by a tuning-fork-shaped head (5) receiving the said rod as well as an immobilising screw (6), characterised in that it consists of two annular elements (9) each capable of being externally fitted onto one of the tuning-fork-shaped heads (5), each annular element (9) comprising an external immobilisation rod (10) which can slide in a clamping collar (11), the two clamping collars (11) of the device being clamped by a common screw (12) passing through the said collars. - Application in particular to spinal osteosynthesis.
