The present study retrospectively investigated clinical outcome at patients with low back pain or sciatica during Chuna treatment (flexion-distraction technique). The study population consisted of 29 patients. Discogenic group consisted of 21 patients who were already diagnosed as HNP of lumbar spine with serial MRIs(magnetic resonance imaging) or CTs(computerized tomography). Simple LBP group consisted of 8 patients with low back pain & sciatica who were non-specific disorder on radiologic examination. All patients were treated with flexion-distraction technique, one of Chuna technique, under analysis of Moire Topography. And the evaluation of clinical outcome was done twice during this study by Moire Topography Analytic Point and Low Back Pain Assesment, Visual Analogue Scale. The results were summarized as follows; Total improvement rate of Moire Topography was $25.8{\pm}17.8%$, and the rate of Low Back Pain Assesment was $56.5{\pm}23.0%$, Visual Analogue Scale of post-treatment was $32.6{\pm}22.5$ Between Improvement rate of Moire Topography and improvement rate of Low Back Pain Assesment, significant correlation was proved(Person's coefficient was 0.381, p<0.05). After all, it is certain improvement of Moire Topography represents symptom's improvement.

현재 전 세계 의료계의 척추 수술 영역에선 다양한 신기술들이 빠르게 개발되어 임상에 적용되어 오고 있다. 논자는 이러한 신기술들이 환자에게 시술되기 전에 효능과 안전성에 대한 검토가 충실하게 이루어지고 있는지 논의해 볼 필요가 있다고 생각한다. 논자는 이 주제를 고찰하기 위해, 2000년대에 추간판성 통증 질환 치료의 신기술로 등장하여 현재까지 전 세계적으로 널리 시술되어오고 있는 추간판 내열 치료술의 기초 연구 자료들과 임상 적용 과정을 분석하였다. 그 결과 이 시술은 효능과 안전성에 관한 기반 연구가 불충분한 상태에서 임상 적용해 온 것으로 평가되었다. 논자는 이 사례가 현재 척추 수술 영역 신의료기술들의 임상 적용과 관련한 본질적 문제를 드러내고 있다고 판단한다. 따라서 논자는 척추 수술 영역의 신의료기술이 환자들에게 미칠 수 있는 부작용을 최소화하기 위해선 보다 충실한 수준의 기초 연구와 보다 높은 수준의 임상 허용기준이 갖추어져야 한다고 생각한다.

Low back pain is generally defined as a complex symptom rather than a specific diseases entity, especially when musculoskeletal lesions of the low back, neurogenic, vasculogenic and discogenic lesions are present. Sixty to eighty percent of all human being have experienced low back pain once or more times during in their lifetime. Low back pain is a one of the commonest cause of physical impairment and induces disability the activities of everyday living or the activities of work. Today, low back pain plays important part for the loss of working capability from social, industrial field and individual daily life. But there are no study about incidence and prevention program of low back pain in rural peoples. This study was conducted to find out current status and characteristics related to low back pain in rural peoples(especially engaged in agriculture), so that could provide basic data to establish prevention program for them. The data were gathered from 301 rural adults(female 62.1%, male 37.9%) with low back pain by the structured interview in the 4 communities(south and north Gyeong-sang Do and Chung-cheong Do), and sampled at local hospital, local clinic, and health clinic center in May, 2000. The results were as followed. About one third of cases(35.5%) were aged from 60 to 69, 34.6% were smoker, and 91.4% not used to regular exercise. Low back pain frequently due to intervertebral articulopathy(42.5%), follewed by herniated intervertebral disk(19.9%), sprain(17.3%), vertebral dislocation(4.0%), and etc(16.2%). Above half of cases(56.5%) were a eight-hour workday, and 61.8% complained of low back pain during work. Mostly, period of agricultural experience was more than 20 years, and cultivated more than 2 crops. Low back pain is common to rural adults, therefore adequate resting time from work and lumbar strengthening exercise program needed to prevent low back pain in rural peoples.

경막외강으로 steroid 및 국소마취제투여는 요통치료에 유일한 방법만은 아니나 여러 대증요법중 가장 관심있는 방법중의 하나이다. 비록 요통이나 혹은 방사통이 동반된 경우에서 경막외강으로 steroid를 투여하여 매우 좋은 결과를 얻었다는 보고도 많다. 더우기 급성이며 짧은 병력올 가지고 수술을 받지 않을 경우에는 더욱 극적인 효과를 볼 수 있다. 경막외강으로는 steroid 단독 혹은 생리식염수나 국소마취제를 steroid의 희석제로 동시 사용하는 경우도 있다. 그러므로 steroid때문에 병세가 호전되었는지 혹은 희석제 때문에 호전 되였는지 분간하기 힘든 경우도 있었다. 그러나 투여후 즉각적인 성공적인 결과라 할지라도 지속성(longevity), 실현성(reality) 및 적응(indication)등에 문제가 있는 것은 사실이다.

Objectives : To demonstrate the need for differential diagnosis between discogenic pain and lumbar sprain and strain in acute low-back pain patients. Methods : Outpatients who made their first visits during May 1, 2009 to Oct. 30, 2009(n=53) were examined by history taking, physical examination, X-rays, and CT imaging. Disorders found on lumbosacral spine X-ray cuts and those on lumbosacral spine CT images were separately recorded. The relationship between treatment period, disc space narrowing and disc degeneration on X-rays, and HIVD on CT images was examined. Results : 1. Correlation between disc space narrowing on X-rays and HIVD found on CT images was analyzed. 21(72.41%) out of 29 patients having disc space narrowing on X-rays and HIVD on CT at the same level required treatment for over 8 weeks. 2. 2(50%) out of 4 Lawrence classification grade I patients, 8(66.67%) out of 12 grade II patients, and 14(70%) out of 20 grade III patients needed treatment for over 8 weeks. Conclusions : Disc space narrowing on X-ray and HIVD on CT at the same level, or disc space narrowing and disc degeneration on X-ray image alone indicate a tendency for treatment periods over 8 weeks, which is longer than the conventional treatment period for lumbar strain and sprain.

A 42-year-old man was admitted to our hospital with complaints of low back pain and intermittent right thigh pain. Twelve weeks before admission, the patient received intradiscal electrothermal therapy (IDET) at a local hospital. The patient still reported low back pain after the procedure that was managed with narcotic analgesics. Follow-up magnetic resonance imaging (MRI) was performed, and his referring physician thought the likely diagnosis was spondylodiscitis at the L4-5 spinal segment with a small epidural abscess. At admission to our department, the patient reported aggravated low back pain. Blood test results, including the erythrocyte sedimentation rate and C-reactive protein levels, were slightly elevated. Biopsy samples of the L4, L5 vertebral bodies and disk were obtained. The material underwent aerobic, anaerobic, fungal, mycobacterial cultures and histologic examination. Results of all cultures were negative. Histologically, necrosis of the bone was evident from the number of empty osteocyte lacunae. In addition, there was no evidence of infection based on biopsy results. No antibiotic treatment was administered on discharge. Repeat computed tomography and MRI performed 12 months after IDET showed a bony defect in the L4 and L5 vertebral bodies, and a decrease in the size of the L4-5 intervertebral disc lesion. We report a case of lumbar vertebral osteonecrosis induced by IDET and discuss etiology and radiologic features.

Recently intradiscal electrothermal therapy is introduced, which is a new and minimally invasive technique fer the treatment of discogenic low back pain. This procedure involves the percutaneous threading of a flexible catheter into the disc under fluoroscopic guidance. The catheter, composed of thermal resistive coil, heats the posterior annulus of the disc, causing contraction of collagen fibers and destruction of afferent nociceptors. This study tries to investigate the effects of the important factors of this procedure such as heat source temperature and heat applying time on the temperature distribution within the intervertebral disc. This study utilized both computer simulation and the experiment for the verification of finite element analysis. FE analysis was carried out with ANSYS v7.0 (ANSYS Inc, USA) using 10,980 number of brick element and 12,551 number of node. The functional spinal units of 5 month old swine were used for the experiment and the temperature was monitored using 10 channel temperature measurement device MV200. Through this study, it was able to analyze the temperature range of inner intervertebral disc by two mechanisms which are known to alleviate pain clinically. The results showed that when the heat source temperature was kept up 80 degree for 1,020 seconds, the temperature of inner annulus reached at 45 degree up to the distance of 15.6mm from heat source, which explains coagulation of inner annulus by heat. When the same heat source was used, the temperature of inner nucleus reached at 60 degree up to the distance of 9mm from heat source, which explains contraction of inner nucleus by heat.

Although several artificial disc designs have been developed for the treatment of discogenic low back pain, biomechanical change with its implantation was rarely studied. To evaluate the effect of artificial disc implantation on the biomechanics of functional spinal unit, nonlinear three-dimensional finite element model of L4-L5 was developed with 1-mm CT scan data. Two models implanted with artificial discs, SB $Charit\acute{e}$ or Prodisc, via anterior approach were also developed. The implanted model predictions were compared with that of intact model. Angular motion of vertebral body, force on spinal ligaments and facet joint, and the stress distribution of vertebral endplate for flexion-extension, lateral bending, and axial rotation with a compressive preload of 400 N were compared. The implanted model showed increased flexion-extension range of motion and increased force in the vertically oriented ligaments, such as ligamentum flavum, supraspinous ligament and interspinous ligament. The increase of facet contact force on extension were greater in implanted models. The incresed stress distribution on vertebral endplate for implanted cases indicated that additinal bone growth around vertebral body and this is matched well with clinical observation. With axial rotation moment, relatively less axial rotation were observed in SB $Charit\acute{e}$ model than in ProDisc model.

Although several artificial disc designs have been developed for the treatment of discogenic low back pain and used clinically, biomechanical change with its implantation seldom studied. To evaluate the effect of artificial disc implantation on the biomechanics of lumbar spinal unit, nonlinear three-dimensional finite element model of L1-L5, S1 was developed and strain and stress of vertebral body and surrounding spinal ligaments were predicted. Intact osteoligamentous L1-L5, S1 model was created with 1-mm CT scan of a volunteer and known material property of each element were applied. This model also includes the effect of local muscles which was modeled with pre-strained spring elements. The intact model was validated with reported biomechanical data. Two models implanted with artificial discs, SB Charite or Prodisc, at L4/5 via anterior approach were also developed. The implanted model predictions were compared with that of intact model. Angular motion of vertebral body, force on spinal ligaments, facet joint contact force with $2\sim12$ Nm flexion-extension moment.
