Anterior corpectomy and posterior instrumentation for scoliosis in neurofibromatosis [a new technique]

ABSTRACT

8 cases of neurofibromatosis with dystrophic scoliosis were treated using this new technique. All patients [3 females and 5 males] were characterized by short angular dorsal curve with kyphosis. Preoperative X-ray and pulmonary functions were done. Surgical management involved anterior corpectomy [one or more, up to 3 bodies were removed] and posterior instrumentation with fusion. The posterior instrumentations used included Harrington distraction rod with or without compression system over the convexity of the curve or rectangular frame. Sublaminar wires were used at all levels in both types of instrumentations. Autogenous bone graft was taken from the prominent adjacent ribs. POP jacket was applied for 3 months to be followed by a brace for a minimum of 3 months till radiological evidence of union was established. This combined procedures were done as one stage procedure. All cases were fused. One case required relocation of upper hook. Average correction was 50%
