Comparison of a Stand-Alone Anchored Spacer Versus Plate-Cage Construct in the Treatment of Two Noncontiguous Levels of Cervical Spondylosis: A Preliminary Investigation

摘要

OBJECTIVE: The application of stand-alone anchored spacer (SAAS) in anterior cervical discectomy and fusion (ACDF) has been proven to be safe and effective to treat cervical spondylosis. Skip-level ACDF with SAAS, fusing only the involved levels without anterior plates, may be the optimal treatment. The aim of the study was to compare the clinical outcomes, radiologic results of SAAS, and plate-cage construct in the treatment of 2 noncontiguous levels of cervical spondylosis.
