Abstract:

The objective of this study is to analyze the reliability and validity of a classification system to assess tibial dysplasia in neurofibromatosis type 1. Radiographs of the lower extremity were collected on 36 individuals with NF1 and tibial bowing. Each radiograph AP and lateral was scored as either type I, type IIA, type IIB, or type IIC by the author of the peer-reviewed published criteria of Crawford Crawford AH and Schorry EK. 1999. J Am Academy of Orthopaedic Surgeons 7217-230. Dr. Crawford scored 16 as type I, 8 as type IIA, 7 as type IIB, and 5 as type IIC. The same set of radiographs was sent to 27 consented volunteers in the radiology and orthopedic communities, and 21 provided a rating. Each volunteer was asked to re-classify the set of radiographs 3 months later to assess the test-retest reliability. 12 reviewers of the first set re-reviewed the radiographs as a second rating. The analyses are underway and being prepared for submission for publication.
