Three of the four clamps were returned for evaluation.Additional information provided that these clamps were not used in a manner consistent with the surgical technique guide.One clamp was placed on each side of the spine and one band was fed across the spine in an attempt to compress a pars fracture.The clamps are intended to receive one band per clamp.It is possible that the cause is user technique, excessive force, improper engagement with the rod and interface with anatomy; however, the exact cause of the reported issue could not be determined.
