Reported here is the result or a study on all spondylolysis patients who were found at the Orthopedic Clinic, Goto Hospital. in the four year period since its opening in May 1965 till April 1968.There were 516 lumbago patients including 294 male and 222 female patients. Among them 123 patients (23.8%) had spondylolysis including 83 male (28.2%) and 40 female (18.2%) patients. Redicular sign was present in 25 per cent of spondylolysis patients. As to the location of lesions, 74 per cent of the patients had spondylolysis in the 5th lumbar vertebra. When the lesion is more than one, it is usually in the 4th and 5th vertebrae. There was one case in which lesions were both in the 2nd, 4th and 5th vertebrae.This higher incidence of spondylolysis may be attributable to the unique closed environment of the Goto Islands, an interesting fact to suggest another etiological factor of spondylolysis.
