Abstract
An osteosynthetic clamp is provided for use in attaching a bone anchor to a support rod. The clamp comprises a carrier with a first portion adapted for connection to the anchor and with a second portion for connection to the rod. A clamping hook defines a bight in which the rod can be located and a head that passes through an aperture defined by the second portion of the carrier. The head of the hook passes through a collar, which is attached to the second portion of the carrier by engaging, complementarily shaped parts. These parts are defined respectively by the second portion of the carrier and by the collar and together form a joint permitting sliding translational movement of the collar relative to the carrier. A fastener can be secured to the head of the clamping hook and tightened in order to clamp the rod within the bight.
