Comparative Study
Clinical validation of functional flexion-extension roentgenograms of the lumbar spine.
The purpose of this study was to determine the clinical validity of functional flexion-extension roentgenograms of the lumbar spine in a defined patient population. One hundred and one adults with low-back pain or functional disorders underwent passive functional flexion-extension examinations. Their roentgenograms were analyzed using a computer-assisted method to determine segmental motion parameters such as rotation and translation of the lumbar vertebrae. ⋯ It was found that all of the patient groups exhibited significantly hypomobile motion, spread equally among all levels, in comparison to the normal population, except for the group of high-performance athletes, who had significant hypermobility. The uniform spread of hypomobility limits the ability to distinguish with any confidence between the four pathologic groups by their motion. Thus, we believe that the analysis of the segmental motion of the lumbar spine using passive flexion-extension roentgenograms does not aid in differentiating the underlying pathologic condition of patients with low-back pain, and that no useful information can be derived form this procedure, especially in relation to the need for surgical intervention.

Back pain after epidural anesthesia with chloroprocaine in volunteers: preliminary report.
The incidence, character and treatment of backache associated with epidural anesthesia (EA) using 3% chloroprocaine (2-CP, Nesacaine-MPF) were observed in ten volunteers undergoing a study of the effects of EA upon plasma catecholamines. Three levels of epidural analgesia were sequentially sought, T10, T4 and C8, in ascending order. Each block was allowed to fully dissipate prior to the next injection. ⋯ Mean verbal analog scale pain scores after regression of the first, second and third blocks were 2.2, 4.3 and 6.5, respectively. Epidural fentanyl (100-200 micrograms) was effective in providing rapid relief of the pain. Large doses or possibly repeated injections of epidural Nesacaine-MPF are associated with an increased incidence and severity of postanesthesia lumbar back pain.

This study (N = 115) compared the abilities of the Faschingbauer Abbreviated Minnesota Multiphasic Personality Inventory (FAM), the Midi-Mult, and the standard MMPI to predict response to conservative medical treatment for low back pain, as assessed by patient ratings of pain intensity 6 to 12 months later. The results indicated that all three inventory formats yielded significant correlations between the Hypochondriasis, Depression, and Hysteria scales and follow-up pain ratings. Less consistent findings were obtained with other scales and indices. The results provide tentative support for the clinical and research utility of these abbreviated MMPIs in substituting for the standard MMPI in outcome studies with back pain patients.

Magnetic resonance assessment of the postoperative spine. Degenerative disc disease.
The magnetic resonance (MR) imaging findings in patients after surgery for degenerative disc disease in the lumbar and cervical spine are discussed. In the lumbar spine, changes seen in the immediate postoperative period, use of Gd-DTPA in distinguishing scar and disc and postoperative complications are reviewed. In the cervical spine, operative approaches and types, the appearance of bony stenosis, and disc herniations are demonstrated.
