    Summary
    This summary is machine-generated.

    Postoperative Minnesota Multiphasic Personality Inventory (MMPI) scores, particularly hypochondriasis and hysteria scales, strongly predict low-back surgery outcomes. Changes in MMPI profiles indicate psychological factors influencing surgical success.

    Area of Science:

    • Psychological assessment in surgical outcomes
    • Spine surgery and patient psychology
    • Neuropsychological evaluation

    Background:

    • Low-back pain significantly impacts patient quality of life.
    • Discogenic disease often necessitates surgical intervention.
    • Preoperative psychological assessment is crucial for surgical candidates.

    Purpose of the Study:

    • To evaluate the relationship between preoperative and postoperative Minnesota Multiphasic Personality Inventory (MMPI) scores and surgical outcomes in patients with discogenic low-back pain.
    • To determine if MMPI profiles are static or changeable in this patient population.
    • To explore the correlation between pain drawings and MMPI scores.

    Main Methods:

    • Follow-up study of 69 patients who underwent low-back surgery for discogenic disease.

    Related Experiment Videos

  • Patients completed preoperative and postoperative MMPI tests, pain drawings, clinical, and radiographic examinations.
  • Surgical outcome was systematically rated.

    • Main Results:

    • Postoperative MMPI hypochondriasis (Hs) and hysteria (Hy) scores were strongly correlated with surgical outcome.
    • Patients with good outcomes showed decreased Hs and Hy scores postoperatively, while poor outcomes correlated with increased scores.
    • Pain drawing scores significantly correlated with elevated Hs and Hy scales.

    Conclusions:

    • MMPI profiles in operated low-back pain patients are dynamic and can change.
    • Identifying patients with neurotic tendencies via MMPI and referring them for psychological treatment may improve surgical outcomes.
    • Favorable response to psychotherapy is associated with better surgical results.
