The best prognosis is a block vertebrae caused by a failure of segmentation. It is an uncommon, inherited disease. It manifests in its most serious form bone abnormalities . Surgical treatment involves posterior fusion with instrumentation if there is less than 50 degrees kyphosis. Anterior fusion and strut grafting combined with posterior fusion and instrumentation is required if there is more serious kyphosis.
Neurologic involvement is the most common complication of neurofibromatosis.
This can be caused by aspects of the deformity itself, by a soft tissue mass, an intraspinal tumour or by dural ectasia. Anterior decompression with strut grafting followed by posterior fusion is required if this happens. It is more common in males and usually manifests in adolescence. Schmorl's nodes are evident. Back This disorder is similar to other forms of Kyphosis but there are no vertebral body changes and no sharp angulation.
