Abstract: BACKGROUND: Adjacent segment disease (ASD) is one of the problematic
complications following anterior cervical decompression and fusion (ACDF).
The impact of additional surgery with instruments is still unknown. OBJECTIVE: The objective of this study was to investigate the surgical
outcomes of additional ACDF with instruments for symptomatic ASD after an
initial ACDF using autogenous iliac grafts without instruments. METHODS: A total of 56 patients who underwent an additional ACDF with
instruments for symptomatic new radicular or myelopathic symptoms from ASD
between 2006 and 2012. In this study, subjects were 30 men and 26 women with
a mean age of 59.2 ± 9.7 years (range, 50-70 years) at revision surgery.
Clinical evaluations were performed preoperatively and repeated at 3 years
after operation. RESULTS: There were no cases of intraoperative complications, major
neurological or vascular, pseudoarthrosis or wound complications. All of
them reported significant improvements in JOA, NDI and VAS on arm pain and
neck pain from the preoperative means (P< 0.05). CONCLUSION: According to our study, additional ACDF with instruments had
achieved favorable clinical results on patients who underwent initial ACDF
using autogenous iliac grafts without instruments for symptomatic new
radiculopathy or myelopathy.
