All spine had spondylopathy appearance at X rays. X rays in posterior anterior, lateral, 45 oblique position and CT figure reconstruction of neuroforamen at each side of C 3~4 , C 5~6 were performed before and after ACDF by turns. Anterior incremental 2 5 mm grafting based on ACDF was applied at C 3~4 and C 5~6 in 10 degenerative cadaver cervical spines. Re performed radio technique figure was analyzed the same as pre operation. Data of statistics included anterior and posterior height of disc space, height of neuroforamen, area and circumference of internal and external os of neuroforamen.Results After grafting 20 segments, the height of neuroforamen increased by 11.2% at C 3~4 and 7 8% at C 5~6 The neuroforaminal areas significantly increased 22 5% at internal os and 23 3% at external os for C 3~4 , 18 2% at internal os and 25% at external os for C 5~6 ; The neuroforaminal circumferences significantly increased 11% at internal os and 12 4% at external os for C 3~4 , 10 9% at internal os and 17% at external os for C 5~6 . Conclusion The incremental grafting can significantly enlarge neuroforaminal height, areas and circumference of internal & external os, providing adequate space for the nerve root and improving neuroforaminal stenosis. As a result, the procedure can be applied to the patients with myeloradiculopathy.

Anterior incremental 2 5mm grafting based on ACDF was applied at C 3 4 and C 5 6 in 10 degenerative cadaver cervical spines. Re performed radio technique figure was analyzed in the same way as pre operation. Data for statistics included anterior and posterior height of disc space, height of neuro foramen, area and circumference of internal and external os of neuro foramen. Results After grafting of 20 segments, the height of neuro foramen increased by 11 2% at C 3 4 and by 7 8% at C 5 6 The neuroforaminal areas significantly increased by 22 5% at internal os and by 23 3% at external os for C 3 4 , 18 2% at internal os and 25 0% at external os for C 5 6 . The neuroforaminal circumferences significantly increased by 11 0% at internal os and 12 4% at external os for C 3 4 , 10 9% at internal os and 17 0% at external os for C 5 6 . Conclusions The incremental grafting can significantly enlarge neuroforaminal height, areas and circumference of internal and external os in elder people, providing adequate space for the nerve root and improving neuroforaminal stenosis. As a result, the procedure can be applied to the elderly patients with myeloradiculopathy.

Objective:To study the significance of X-ray in the diagnosis of the cervical spondylot-ic radiculopathy through the oblique dynamic sagittal distance,which was measured by an improved method.Methods:Lateral,double oblique,much extensive and much flexional photographs of the cervical were taken with Kodak com.ACR-2000i computer image system in100adults.The sagittal distance of nerve root canal(a)and the oblique sagittal distance of same vertebra inferior border(b)were measured,then the ratio of cervical nerve root(a /b)was calculated.Results:The mean ratio s of neutrality,over flex-ion and over extension were0.37,0.35,0.45respectively.The standard deviation was0.06.Conclusion:When the ratio is below0.30,it is thought that the nerve root canal is stenosis.The ratio of dynamic nerve root canal is an effective and sensitive index to diagnose the cervical spondylotic radiculopathy and may be useful in the choice of therapy methods.
