[Myelographic diagnosis and treatment of lumbosacral nerve root anomalies].
Altogether 480 patients were examined with myelography in the study from 1987 to 1992 and 28 cases having anomalous lumbosacral nerve roots with other concomitant diseases were found. The anomalies were classified three types based on myelographic findings. Type 1, root sleeve displacement; Type 2, a, roots through one foramen; b, roots through two foramina; c, roots through three foramina; Type 3, double roots through one foramen. All patients were proved and treated during operation. The results of treatment were good (92.8%). We considered that most lumbosacral nerve roots anomalies were asymptomatic, however, when they were compressed by degenerative canal tissue, classic nerve root pain appeared eventually. Myelography is helpful to its diagnosis and treatment.
