Failure of fusion of the posterior arches of the lumbosacral spine above S3 was sought on frontal radiographs of 653 patients attending an accident and emergency (A & E) department. The patients were aged from 2 months to 98 years and represent all those with relevant information discharged as A & E outpatients over a 2-year period. Presenting complaints of backache or enuresis and inadequate radiographs were excluded. Spina bifida occulta was diagnosed in 22% of the whole group. The incidence was much higher in those below the age of 40 years (29.2%) compared with those above (9.8%). The overall age-adjusted incidence was 17.3%. Our study is an attempt to judge the off-the-street' prevalence of spina bifida occulta. It supports the notion that spina bifida occulta is a common anomaly, of no clinical significance on its own.
在653名前往急诊部就诊的患者的腰椎正位X线片上，寻找S3以上腰骶椎后弓融合失败的情况。这些患者年龄从2个月到98岁不等，代表了在两年时间里作为急诊门诊患者出院的所有有相关信息的患者。排除了主诉背痛或遗尿以及X线片质量不佳的患者。在整个研究组中，隐性脊柱裂的诊断率为22%。40岁以下人群的发病率（29.2%）远高于40岁以上人群（9.8%）。总体年龄调整发病率为17.3%。我们的研究旨在判断隐性脊柱裂的“实际”患病率。它支持隐性脊柱裂是一种常见异常、本身无临床意义这一观点。
