Patent ID: 7572277

Claim:
A spinal osteosynthesis device, comprising: a connector defining a protrusion opening extending along an axis and configured to receive a protrusion that is affixed to a vertebra; the connector defining two rod openings configured to receive rods; the protrusion opening intersecting the two rod openings to define rod contacting orifices; a rod contacting member having rod contacting surfaces, the rod contacting surfaces being located in the rod contacting orifices to directly clamp against the rods in the two rod openings of the connector; wherein the connector defines a groove configured to permit deformation of the protrusion opening for retaining the rod contacting member in the connector; wherein the connector has a sidewall including the groove; wherein the groove extends through the sidewall from an outer face of the sidewall and intersecting the protrusion opening in a direction transverse to the axis to define an overhang region of the connector; and wherein the overhang region is permanently deformed to protrude over the rod contacting member in the protrusion opening.
