Osteosynthetic holding system

Abstract

An osteosynthetic holding system is provided which comprises bone anchoring elements, each of which has a clamping element as well as two receptacles arranged thereon for receiving holding bars. The receptacles have blocking elements arranged thereon which define accesses to the receptacles. Two holding bars are provided which are insertable into the receptacles of each bone anchoring element. The clamping element can be tightened to clamp the two holding bars against the receptacles, thereby fixing the position of each bone anchoring element with respect to the other. The blocking elements, together with the clamping element in a tightened state, constrict the accesses to said receptacles in a direction transverse to a longitudinal direction of the holding bars such that the holding bars no longer fit through the accesses. The blocking elements of the two receptacles are dimensioned such that upon releasing the clamping element, the accesses to the two receptacles are enlarged to enable each of the holding bars to fit through its respective receptacle in turn as the clamping element is released.
