Multicenter Study Clinical TrialClinical and radiological evaluation of the Codman semiconstrained load-sharing anterior cervical plate: prospective multicenter trial and independent blinded evaluation of outcome.
Semiconstrained load-sharing implants for spinal fixation accommodate change in the screw-plate interface as bone grafts shrink. The authors evaluated the clinical and radiological outcome in patients after placement of the Codman anterior cervical plate (ACP) system, which allows change in the screw-plate angle. ⋯ Based on an independent blinded evaluation, the Codman ACP provides effective fixation with load sharing and is effective in achieving fusion with a 94% success rate. Direct comparison with rigidly locked devices is required to establish definitively the optimal method for anterior cervical fixation.
