Fifty‐year survival and neurological deficit at birth in 117 consecutive, unselected cases of open spina bifida. Those born with a sensory level below L3 were more likely to survive than those with a higher sensory level (54% vs 22%, logrank p=0.001) at mean age 50y. One minimally affected case (with an S1 sensory level) was lost to follow‐up after the age of 43y. At age 50y, results have been censored for 17 cases who were alive (aged 46–49y) in August 2017.
