a 14-year-old boy with NF1 related lumbar kyphoscoliosis associated with CCI and dystrophic vertebral rotatory subluxation at L2/3 & L3/4 levels (lumbar type) (a, b and c). Stage 1 posterior spinal correction and fusion surgery was performed with low screw density yet with generous posterior fusion, followed by stage 2 supplementary anterior intervertebral fusion utilizing autogenous rib grafts (d, e, g). The coronal balance was well reconstructed despite low correction rate of main curve (d, f). 2.25-year-follow up revealed satisfying intervertebral fusion (h) and well maintenance of coronal balance with no instrumentation failure (i, j)
