Abstract

What is provided is a fixation system that offers a strong and stable construct for maximum fusion augmentation and yet is versatile enough for any patient and is easy to use. Disclosed is a connection assembly for connecting a spinal implant, the assembly comprising: a body, the body including a body opening for receiving at least a portion of a first connector; a swivel having first and second ends and being operatively connected to the body, the first end including a swivel opening for receiving at least a portion of a second connector having a plurality of teeth for locking; a locking plate having an arm at least partially extending into the body opening; a locking unit operatively connected to the body and contacting the second end of the swivel; and whereby activation of the locking unit causes the arm to engage the first connector and swivel opening to engage the second connector thereby preventing relative rotation between the first and second connectors.
