Dystrophic Spinal Deformity in Neurofibromatosis: PDF OnlySirois Joseph L. III M.D.; Drennan, James C. M.D.Journal of Pediatric Orthopaedics: July-August 1990 - p 522-526 Buy Abstract Summary: A retrospective review was performed to investigate patterns of spinal deformity associated with neurofibromatosis and the incidence of pseudarthrosis and curve progression after spinal fusion. Twenty-three of the 32 patients (72%) with spinal deformity had dystrophic curve patterns. The incidence of pseudarthrosis was 38% for the dystrophic group undergoing isolated posterior fusion. Their average curve progression was 12.7° and required an average of 1.7 procedures to achieve solid posterior fusion. Kyphoscoliotic curves should be treated with combined anterior/posterior fusion.
