This is a case report of an eight-year old boy with neurofibromatosis and a 120 degrees dystrophic kyphosis of the cervical spine. He presented with progressive quadriparesis caused by spondyloptosis of the C2/C3, and was successfully treated by skull traction and one-stage anterior fibular strut graft lying between the tubercle of the atlas through the C2 body slot and lower vertebrae. At seven years follow-up there was, loosening of lower vertebral screws which allowed growth and residual mobility of lower vertebral joints while the fusion of upper cervical spines was still solid.
