Comparison of ultrasonography- and fluoroscopy-guided facet joint block in the lumbar spine.
Retrospective study. ⋯ We should consider that ultrasonography-guided facet joint block is a minimal invasive procedure that is easily carried out without radiation exposure.

Factors affecting clinical results after corrective osteotomy for lumbar degenerative kyphosis.
This study is a prospective, clinical study for lumbar degenerative kyphosis. ⋯ There is no correlation between preoperative degree of kyphotic deformity and clinical outcomes. The degree of anterior rotation of pelvic tilt does not change significantly; rather, compensatory mechanisms of the pelvis and BMI were found to have more influence. Because neither the degree of satisfaction with clinical outcomes nor the increased activity was relatively higher, a more sincere decision should be made before recommending corrective osteotomy for degenerative lumbar kyphosis.

Thoracic disc herniation of the adjacent segment with acutely progressing myelopathy.
We report a case of a 66-year-old woman with progressing myelopathy. Her history revealed instrumented fusion from T10 to S1 for degenerative lumbar kyphosis and spinal stenosis. The plain radiographs showed narrowing of the intervertebral disc space with a gas shadow and sclerotic end-plate changes at T9-T10. ⋯ The patient was treated with a discectomy through the posterior approach combined with posterior instrumentation. The patient's symptoms and myelopathy resolved completely after the discectomy and instrumented fusion. The thoracic disc herniation might have been caused by the increased motion and stress concentration at the adjacent segment.

An analysis of the prognostic factors affecing the clinical outcomes of conventional lumbar open discectomy : clinical and radiological prognostic factors.
This is a retrospective study. ⋯ Following an analysis for detecting the prognostic factors of open discectomy, the final clinical outcome was found to be poor for the revision surgery cases. In regard to the type of herniation, the degree of low back pain was relatively lower at a final follow-up for the extruded cases as compared with that for the protruded or sequestrated cases. Open discectomy surgery should be performed after evaluating the patients' various prognostic factors that could affect the final clinical outcome.

Pain is perceived and then it is operated on in the cerebral cortex by several processes such as transduction, transmission, modulation and perception. We have to know the exact mechanism of pain. The purpose of this review is to explain the mechanisms of pain and to discuss the definitions of the terms related to pain. We also review the mechanisms of the analgesic effect of the pharmaceuticals we use to control pain.
