Fig. 6From: How to rectify the convex coronal imbalance in patients with unstable dystrophic scoliosis secondary to type I neurofibromatosis: experience from a case seriesa 26-year-old male patient with NF1 related lumbar kyphoscoliosis associated with CCI (lumbar type) (a, b). Posterior spinal correction and fusion surgery was performed with over correction of upper hemi-curve, resulting in iatrogenic aggravation of CCI (c). Despite spontaneous improvement of CCI during follow-up (e), rod fracture occurred at 2-year-follow up (e, f, g, arrow). Revision surgery was performed with satellite rods (four rod constructs) and generous posterior fusion, and no additional rod fracture occurred by 5-year-follow up (h, i)Back to article page
