Background: In order to find out the effect of therapy methods through Flexion-distraction technique and drop technique on pain, sacral angle of patients with lumbar herniated intervertebral disc targeting patients with lumbar herniated intervertebral disc due to L5-S1. Method: This study was to present the directivity of the therapy method for lumbar herniated intervertebral disc by comparing and analyzing the spinal decompression therapy and provide an effective treatment method to patients with lumbar herniated intervertebral disc by identifying the therapeutic effect of Flexion-distraction technique and drop technique. The research period is March 1, 2018 to June 30, 2018 and subjects are the patients diagnosed as lumbar herniated intervertebral disc due to L5-S1 by their doctor through clinical findings and medical equipment such as X-ray, CT, MRI etc. Among patients who visited and hospitalized in S Orthopaedics located in Daegu and 30 female patients with sacral angle of more than $30^{\circ}$ were randomly classified into 15 people and we carried out treatment three times a week for 8 weeks for 15 people in the experimental group applying Flexion-distraction technique and drop technique and 15 people in the control group applying spinal decompression therapy to compare and analyze the changes in pain, sacral angle of patients with lumbar herniated intervertebral disc. Result: According to the results of this study, changes in the Visual Analogue Scale showed statistically significant differences in both the experimental group and control group(p<.05), while there was statistically significant difference in the comparison between groups before and after measurement of experimental group (p<.05). In the comparison within two groups of sacral angle, both groups showed statistically significant difference(p<.05) but there was no statistically significant difference in the comparison of scores between groups before and after measurement of each group(p>.05). Discussion: All those results the above proved that we need to confirm various benefits of the therapy with the flexion-distraction technique and drop technique, and the findings of the concerned study will possibly become useful information when doctors actually work on a therapy to treat patients with the lumbar herniated intervertebral disc.

Background: Intradural-intramedullary intervertebral disc extrusion (IIVDE) is a rare condition of intervertebral disc disease. However, the diagnosis of IIVDE is challenging because the prognosis and imaging characteristics are poorly characterized. Objectives: We aimed to describe the clinical and imaging characteristics of tentatively diagnosed IIVDE in dogs to assess the prognostic utility of neurological grade and magnetic resonance imaging (MRI) findings. Methods: Twenty dogs were included in this retrospective cohort study. Results: Nonchondrodystrophic breeds (n = 16) were more predisposed than chondrodystrophic breeds. Most dogs showed acute onset of clinical signs. Neurological examination at admission showed predominant non-ambulatory paraparesis (n = 9); paresis (n = 16) was confirmed more frequently than paralysis (n = 4). Follow-up neurological examination results were only available for 11 dogs, ten of whom showed neurological improvement and 8 showed successful outcomes at 1 month. The characteristic MRI findings include thoracic vertebra (T)2 hyperintense, T1 hypointense, intramedullary linear tracts with reduced disc volume, and cleft of the annulus fibrosus. None of the MRI measurements were significantly correlated with neurological grade at admission. Neurological grade did not differ according to the presence of parenchymal hemorrhage, parenchymal contrast enhancement, and meningeal contrast enhancement. Neurological grades at admission showed a statistical correlation with those observed at the 1-month follow-up (r = 0.814, p = 0.02). Conclusions: IIVDE is a rare form of disc extrusion commonly experienced after physical activity or trauma and most frequently affects the cranial-cervical and thoracolumbar regions of nonchondrodystrophic dog breeds. Neurological score at admission emerged as a more useful prognostic indicator than MRI findings in dogs with suspected IIVDE.

최근 요통의 원인을 밝히기 위한 노력의 일환으로 의료 영상 자료를 이용하는 연구가 많이 이루어지고 있는 실정이나 의료 영상 장비들은 사용 비용이 고가라는 점, 인체에 침습적이라는 점 그리고 추간판의 크기를 측정하기 위해서는 이를 구현할 수 있는 소프트웨어가 필요하다는 점 등의 제한점으로 인해 연구 환경에서는 그 사용이 제한적으로 이루어지고 있는 실정이다. 이에 본 연구는 비교적 신뢰도가 높으면서 신체 계측 자료를 이용하여 간단한 추정식에 의해 추간판의 크기를 추정할 수 있는 Colombini 등의 방법과 이를 수정하여 보다 발전시킨 Turk와 Celan의 방법을 소개하고 이들의 방법에 의해 추정된 추간판의 크기가 의료 영상 자료에 의한 실계측치와 유의한 상관성이 있는가를 알아보기 위하여 수행되었다. 본 연구는 근골격계 질환이 없는 20대의 정상 성인을 대상으로 신체 계측을 통해 구해진 자료를 Colombi의 추정식과 Turk와 Celan의 추정식으로 처리한 후 이를 통해 구해진 L4-5, L5-S1 추간판의 크기를 CT 영상을 통해 구해진 실계측치와 비교하는 방식으로 진행되었다. 본 연구 결과 L4-5와 L5-S1 추간판의 크기는 Colombi 추정식에 의해 구해진 값이 Turk와 Celan 추정식으로 구한 값이나 CT 영상을 통해 얻어진 실계측치 보다 약간 큰 것으로 나타났으나 Turk와 Celan의 값과 CT에 의한 실계측치 사이에는 유의한 차이가 없었다. 따라서 신체 계측을 통한 추간판 크기의 추정 방법인 Turk와 Celan의 공식이 CT 실계측과 매우 높은 상관성을 가진다는 것을 알 수 있었다.

Objective : Little is known about the comprehensive molecular and biological mechanism on the development of the degeneration of the intervertebral disc. Many kinds of matrix metalloproteinase[MMP] initiate the degradation of the extracellular matrix including several kinds of collagens and proteoglycans. We compared molecular and immunohistochemical features of degenerated intervertebral disc and normal counterparts in order to investigate the role of MMP-1, 2, 3, 9. Methods : We have evaluated MMP-1, 2, 3, 9 expression in 30 surgically resected lumbar disc from degenerative disc disease patients and 5 normal control cases. RT-PCR[reverse transcriptase-polymerase chain reaction] and immunohistochemistry were performed. Results : By RT-PCR, normal tissue samples showed merely scant expression of MMP-1, 2, 3, 9 mRNA, but degenerated disc samples revealed more pronounced expression. mRNA amplifications were detected in 60%, 63.3%, 70%, 53.3% cases By immunohistochemistry, normal tissue samples showed minimal protein expression of MMP-1, 2, 3, 9, but degenerated disc samples revealed more pronounced expression. Protein expressions were detected in 73.3%, 63.3%, 76.7%, 63.3% cases. Both the mRNA amplification and protein overexpression rates were significantly higher in degenerated disc than in the normal tissue. Concordance between both the mRNA amplification and protein expressions of MMP-1, 3, 9 were not observed, but there is well correlation in MMP-2 expression. Conclusion : We concluded that the over-expressions of the MMP-1, 2, 3, 9 may contribute to the development of degeneration of the intervertebral disc.

Objective: This study aimed to investigate the short-term effects of flexion-distraction spinal manipulation on intervertebral height, pain, spine mobility in patients with lumbar degenerative disc disease. Design: Randomized controlled trial with a pretest-posttest control group design Methods: A total of 96 participants with degenerative disc disease participated in the study and were randomly divided into two groups. Both groups received intervention for 3-5 minutes a day. The experimental group (n=48) underwent flexion-distraction spinal manipulation for 3-5 minutes, and the control group (n=48) was maintained in the same position as the experimental group for 5 minutes without any intervention. The intervertebral height was measured by computed tomography, pain was assessed using visual analog scale, and the spine in flexion mobility was measured using the finger-to-floor distance test and passive straight leg raise test. Pre-test and post-test measurements were obtained. Results: The experimental group showed significant improvement in intervertebral height, degree of pain, and spinal mobility (p<0.05). The intervertebral height increased from 6.32±1.90 to 6.93±1.85 mm (p<0.05), lower back pain decreased from 69.17±13.35 mm to 48.48±12.20 mm (p<0.05), lumbar spine mobility changed from 17.37±4.49 to 12.69±4.34 cm (p<0.05), and passive straight leg raise test range increased from 46.94±13.05° to 56.01±12.20° (p<0.05). Conclusions: This study suggests that flexion-distraction spinal manipulation could be an effective treatment for decreasing pain and improving function in patients with degenerative disc disease.

The histological and histochemical study of the body of axis and 1st intervertebral disc in the Korean native cattle fetus was attempted to early developmental process. The experimental animals used in this study were collected from fetus of the Korean native cattle ranging from 50mm to 180mm in Crown-Rump length(CR-length). The results were summerized as follows: 1. The ossification centers appeared centrum 1 and centrum 2 of the axis in 110mm CR-length fetus of the Korean native cattle. The centrum 2 was formed little earlier than the centrum 1. 2. The histochemical reactions for collagenous fibers in the axis revealed negative in 50mm CR-length, mild positive in 90mm CR-length, and strong positive in 110mm CR-length, respectively. 3. Dense collagenous fibers were observed in the notochord through the centrum 2, and intervertebral disc developed into cuneiform dorsoventrally, It's contour looks like an annual ring. These fiber bundle arranged lamellar formation. 4. The intervertabral disc of 50mm CR-length fetus was composed mainly mesenchymal cells, and these cell showed aggregation in the central portion. The intervertebral disc of 110mm CR-length fetus was consisted of pricipally fibroblast, and notochordal sheath formed with two layers in the center.

Objective : Spinal nerve root compression occurs commonly in conditions, such as herniated nucleus pulposus, spinal stenosis, intervertebral foraminal stenosis, and trauma. However, the pathophysiolosy of the symptoms and signs related to spinal nerve root compression is poorly understood. The purpose of the present study was to assess and compare the changes of various pressures of intervertebral foraminal pressure before and after decompression. Method : After laminetomy without foraminotomy was performed, pressure sensor tip of Camino parenchymal type was located at the middle-central portion of the intervertebral foramen and anterior portion of nerve root for the foraminal pressure before decompression of the intervertebral foramen. After laminectomy with foraminotomy, the same method was used for the foraminal pressure after decompression. The authors studied 40 consecutive patients (57 disc spaces) with severe constant root pain to the lower leg, pain unrelived by bed rest, and minimal tension signs, diagnosed by MRI. Results : In patients with intervertebral foraminal stenosis, the intraforaminal pressure was decreased from $86{\pm}2.23mmHg$ to $17.1{\pm}1.51mmHg$ and in patients without stenosis, from $55.9{\pm}1.08mmHg$ to $11.9{\pm}1.25mmHg$. All patients below 20mmHg after decompression showed good outcome, but 4 cases who showed poor outcome had foraminal stenosis, posterolateral type of the herniated disc, and above 30mmHg of foraminal pressure after decompression. Conclusion : These findings suggest that if the foraminal pressure falls below 20mmHg after decompression, good outcome can be anticipated. Central type of the herniated disc shows better outcome compared to the posterolateral type.
