| Abstract: | This study was done to determine whether the Minnesota Multiphasic Personality Inventory (MMPI) aided in selection of appropriate lumbosacral fusion candidates, compared with those selected without an MMPI. Postoperative end-result ratings were done, categorizing patients into two groups: one group of 62 patients with a preoperative MMPI and a second group of 23 patients with no preoperative MMPI. Thirty patients with normal MMPIs, strong objective indications for initial surgery, and absence of compensation and/or litigation factors had 88% good or excellent end-results. Twenty-three patients had surgery without MMPI evaluation. Of 21 available for follow-up, 86% had good or excellent end-results. "Warning" physical signs aided selection of appropriate surgical candidates in the patients who did not have an MMPI. |
