Percutaneous radiofrequency denervation of spinal facets. Treatment for chronic back pain and sciatica.

A technique for radiofrequency localization and coagulation of articular nerves supplying the spinal facets is described and results are reported from a series of 207 patients followed 6 to 21 months (mean 31 months). Relief of pain was achieved in 79% of previously unoperated patients, in 41% of those with laminectomy but no fusion, and in 27% of those with an earlier fusion. No neurological complications were encountered.

The role of HLA B27 in the diagnosis and management of low-back pain and sciatica.

Present diagnostic criteria for ankylosing spondylitis (AS) lean heavily on the x-ray examination, but there is much dispute as to its efficacy, especially in mild or early cases. Determinations of the HLA B27 histocompatibility antigen appear to define the population at risk far better than any other means. Of 31 patients who had the HLA B27 antigen, all had negative latex fixation tests and axial polyarthritic complaints (seronegative spondyloarthropathy or rheumatoid variant). Three had Reiter's syndrome and one had ulcerative colitis. Of the remaining 27 patients, nine had definite AS, 11 had probable AS, and seven had possible AS. Eleven of the 27 underwent at least one invasive spinal procedure (myelogram, laminectomy, fusion, facet denervation) before a diagnosis of AS was made.

Quantification of thermal asymmetry. Part 2: Application in low-back pain and sciatica.

Temperature differences between the lower extremities were measured using a computerized thermometric scanning system in order to compare the degree of thermal asymmetry in 144 patients with low-back pain. The patients displayed highly significant thermal asymmetries, with the involved limb being cooler (p less than 0.001). When asymmetries exceeded 1 standard deviation from the mean temperature of homologous regions measured in 90 normal control subjects, the positive predictive value of thermometry in detecting root impingement was 94.7% and the specificity was 87.5%. These values indicate that calculation of temperature asymmetry is particularly effective in evaluating reported pain in psychosocially affected patient populations in whom the chance of positive myelography or impaired root function is low. In this group of patients, thermometric study provides physicians with important information for proper decision making. The test can be performed to avoid more invasive and probably less revealing diagnostic or exploratory surgical procedures.

Outcome evaluation of the operative management of lumbar disc herniation causing sciatica.

OBJECT: The authors conducted a study to assess health-related quality of life (HRQOL) and the appropriateness of surgery in patients who have undergone elective lumbar discectomy. METHODS: The study involved a prospective cohort of 82 surgically treated patients with lumbar disc herniation causing lower-extremity radiculopathy. An independent study coordinator recorded demographic data and administered the North American Spine Society (NASS) lumbar spine instrument and the Short Form-36 (SF-36) before treatment, and at 6 months and 1 year after surgery. The HRQOL results were also compared with normative data for the NASS and SF-36. The influence of baseline variables on HRQOL was determined using regression modeling. The InterQual Indicators for Surgery and Procedures (ISP) were used to compare surgeon practice patterns with standardized indications for surgery. The NASS neurogenic symptom (NSS) and pain/disability scores (PDSs) showed very significant improvement at 6 months and little change between 6 months and 1 year. The SF-36 physical function and bodily pain scale scores were associated with the greatest improvement. Interestingly, the 1-year NASS (NSS and PDS) and SF-36 (only PCS) scores remained lower than those of age-matched normative data. Other than preoperative HRQOL scores, the only other variable that inversely influenced HRQOL was the duration of time between symptom onset and surgery. Ninety-five percent of ISP forms were completed, and 97% of the indications recorded by the surgeon matched the criteria. CONCLUSIONS: The reporting of standardized outcomes in association with indications for surgery is feasible and may help elucidate the ideal rate for discectomy.

Recurrent sciatica due to periligamentous trapped epidural gas after spinal sequestrectomy.

The authors describe the unusual case of a 50-year-old woman who suffered from sciatic pain due to periligamentous trapped epidural gas after lumbar sequestrectomy. The patient underwent removal of free herniated disc material via a translaminar approach through the L-5 lamina without discectomy. Four days later she suffered from recurrent pain, and neuroimaging studies revealed an epidural gas formation at the site of the sequestrectomy. After evacuation of the gas, her pain resolved. Postoperative intraspinal gas may be symptomatic in the rare case.
