title: Dystrophic thoracic spine dislocation associated with type-1 neurofibromatosis: Case report and rationale for treatment.
abstract: The authors report a rare case of spontaneous dystrophic thoracic spine dislocation in a 14-year-old boy with neurofibromatosis type 1 (NF-1). Anteroposterior and lateral standing radiographs showed a dysplastic kyphoscoliotic deformity, with the thoracic kyphosis and scoliosis measuring 75° and 69°, respectively. Three-dimensional reconstruction after computed tomography demonstrated spondyloptosis at T5-T6 with overlapping of T5 over T6 and T7. The patient underwent circumferential fusion with anterior fibular strut grafting mechanically secured between the inferior and superior endplates of T5 and T7 followed by an instrumented posterior fusion from T2 to L1 and thoracoplasty. There was satisfactory resolution of the deformity with stabilization at the last follow-up evaluation.
