ABSTRACT: Study Design: Prospective cohort studyObjective: To investigate the fate of posterior osteophytes after anterior cervical discectomy and fusion (ACDF) using computed tomography (CT).Summary of Background Data: As a method of ACDF, indirect decompression through interbody height distraction and spontaneous posterior osteophyte resorption has the advantage of reducing complications that can occur during direct decompression. However, the outcome of resorption, of the posterior osteophytes, has not been considered to be satisfactory.Methods: Thirty one patients underwent ACDF with plate fixation for cervical spondylotic radiculomyelopathy. The areas and lengths of the most prominent posterior osteophytes, in each patient, and the anteroposterior (AP) diameter of the intervertebral foramen, were measured from CT images using commercial software.Results: Among 31 patients, the posterior osteophytes decreased in seven (23%), increased in five (16%), and were unchanged in 19 (61%). The mean change of area of prominent posterior osteophytes (ΔArea5 years-3 months) was -0.42±4.21 mm. There was no statistically significant change between Area3 months and Area5 years (p = 0.82). The mean change of length (ΔLength5 years-3 months) was -0.02±0.41 mm. There was no statistically significant difference between Length3 months and Length5 years (p = 0.84). The mean AP diameter of each intervertebral foramen of fused segments did not change significantly between three months and five years postoperatively on oblique foraminal images (C5 Rt. p = 0.31, Lt. p = 0.56, C6 Rt. p = 0.61, Lt. p = 0.49) and axial images (C5 Rt. p = 0.61, Lt. p = 0.49, C6, Rt. p = 0.71, Lt. p = 0.51).Conclusion: Contrary to previous reports, there was no evidence of consistent posterior osteophyte resorption during five years of follow-up. |
