Abstract

A spinal cross-connector comprises an elongated member, a first connector and a second connector. The first connector and the second connector are configured to receive spinal rods and adaptable to directly attach with pedicle screws. The first connector includes a first collet head, a first clamp and a first locking means. The second connector includes a second collet head, a second clamp and a second locking mans. The first locking means is configured to tighten over a first collet head and engage with the first connector.
