Lumbar Connecting Rods

Connecting rods are top-loaded in pedicle screws or hooks to connect them together. These smooth cylindrical rods are tightened by the locking screw in order to stabilize the osteosynthesis system. Two main different types of connecting rods are available: Straight and pre-bent. 

Rods are available in Titanium alloy (TA6V), pure titanium (T40) and Cobalt-Chromium alloy. The connecting rods have a diameter of 5.5mm for most of them and are available in several lengths to suit all clinical cases. MISS rods are also available with a specific extremity for coupling with MISS instrumentation. There are also TA6V rods providing locally slightly more elasticity for softer stabilization to promote fusion with optimal graft compression. This softer stabilization helps to protect the adjacent level. These rods are called “flexible”. Pre-bent rods help to restore the lordotic and kyphotic anatomies of the spine
