Connection System Between a Spinal Rod and a Transverse Bar

摘要

A system for connecting a spinal osteosynthesis rod and a crossbar include a passage for receiving the crossbar and hinge mounted jaws for clamping the rod. A locking device biases the crossbar against the jaws. A return spring pulls the jaws relatively close to one another independently of the crossbar such that the jaws may clamp the osteosynthesis rod to ensure a stable mounting of the connection system to the osteosynthesis rod.
