Years Ago

One of the most commonly quoted arti-
cles in the spine literature was published by E.J. Holt, Jr., in
1968 [1]. Based on study of prisoners who had volunteered
to undergo discography, Holt reported 37% false-positive
discograms in asymptomatic subjects. In the same year, an-
other study concluded that discography was valuable and
associated with few complications [2]. Holt’s study was
critically reviewed by Simmons et al. in 1988 [3].
