Abstract
We analysed 100 patients following anterior cervical discectomy and fusion with interbody stabilisation with PEEK cages. Radiographs obtained preoperatively and during the 12-month follow-up were compared to track changes in overall and local cervical lordosis and disk space height. Subsidence was defined as cage migrationâ¯â¥â¯3â¯mm into the adjacent endplates. Mean change in operated disk space height was 1.13â¯Â±â¯1.33â¯mm. Subsidence was detected in 10.23% of the operated spaces. Mean change in overall cervical lordosis was 1.31â¯Â±â¯5.71 degrees, and mean change in local lordosis was 0.19â¯Â±â¯4.71 degrees. Change in overall cervical lordosis correlated with change in local lordosis (râ¯=â¯0.61, pâ¯<â¯0.01). The greatest changes in lordosis and disk space height were noted immediately post-surgery. Baseline values were approximated gradually over time, but the post-operative values at 12â¯months were still higher than baseline. Disk space height change did not correlate with changes in patient-reported pain intensity at baseline (VAS 0) vs. at 12â¯months post-operatively (VAS 12) (râ¯=â¯0.12, pâ¯<â¯0.05) or changes in the Neck Disability Index (NDI) at baseline (NDI 0) vs. at 12â¯months post-operatively (NDI 12) (râ¯=â¯â0.02, pâ¯=â¯0.05). Changes in overall cervical lordosis did not directly influence treatment outcomes assessed by comparing VAS 0 vs. VAS 12 (râ¯=â¯0.13, pâ¯=â¯0.24) or NDI 0 vs. NDI 12 (râ¯=â¯â0.0005, pâ¯=â¯0.96). Surgical outcomes depend primarily on adequate decompression of the spinal cord and nerve roots. Post-operative radiological changes did not directly influence patients' pain level or quality of life.
