Patients avoiding surgery. Pathology and one-year life status follow-up.

Patients were selected for a research study to determine the outcome of patients who had demonstrated enough pathology to have been viewed as surgical candidates and had chosen to avoid surgery. The purpose of the study was to identify the diagnostic categories and to obtain follow-up data on these patients. The patient population consisted of 66 patients with the following pathologies: disc disruption (one and two levels), disc disruption (three levels), stenosis, spondylolisthesis, instability, and herniated nucleus pulposus. The patients were followed for a period of 1 1/2 years and rated on the following lifestyle status categories: Returned to Work, Retired, Retraining, Able to Increase Activity Level, or No Change from Initial Status. Of the nonoperative patients, 18% returned to work. Twelve patients (18%) were retired. Eleven patients (16%) were placed in retraining programs. Twenty patients (29%) were able to increase activity level. Eleven patients (16%) fell under the category of no change.

Pain provocation and disc deterioration by age. A CT/discography study in a low-back pain population.

The computed tomography (CT)/discograms and discographic pain provocation reports of 291 clinical patients, 790 discs (mean age, 38; range, 17-79) were collected. The CT/discograms were classified separating anular disruption and degeneration and recording the pain provoked during discography as no pain, dissimilar, similar, or exact reproduction of the patient's clinical pain. Nondegenerated discs usually were found to be painless, and deteriorated discs painful. The proportion of severely degenerated but painless discs increased with age, as did the discs producing dissimilar pain. This may help explain the poor correlation of low-back pain with radiographic degenerative changes reported in previous epidemiologic studies.

The development of the Dallas Pain Questionnaire. An assessment of the impact of spinal pain on behavior.

The Dallas Pain Questionnaire (DPQ) was developed to assess the amount of chronic spinal pain that affects four aspects (daily and work-leisure activities, anxiety-depression, and social interest) of the patients' lives. Results of the DPQ's statistical properties suggest that the DPQ is an externally reliable instrument as well as internally consistent. Two factors emerged from factor structure analysis. Factor 1 represents functional activities and Factor 2 represents emotional capacities. A correlation analysis suggests the concurrent validity of the psychological functional factors of the DPQ. A t test demonstrated that chronic pain patients have significantly higher DPQ scores than normals. Because these findings support its statistical properties, the DPQ appears to have utility for clinical and research purposes. The findings, limitations, and implications of this study are detailed, as are suggestions for future research.
