This study analysed 20 patients disabled with lumbar spinal problems and assessed personality factors using the Minnesota Multiphasic Personality Index. In 4 cases (20%) either Hs or D or Hy or Pd exceeded a t-score of 70. There were no significant differences in number of operations or kind of treatment. In this study MMPI results do not appear to be not related to surgical outcome. MMPI information must be used with considerable caution in MMPI scales and cord types.
