  • 요추의 중립위, 굴곡위 및 신전위에서의 응력 분포의 차이와 수핵의 유무에 따른 응력 분포의 변화를 관찰하기 위해 본 연구를 시행하였으며 등색선의 양상을 관찰하고 그 응력을 해석하여 다음과 같은 결론을 얻었다. 1. 기립 중립위에서는 수핵이 있는 경우는 전방 부위보다 후방부위에 고응력이 집중되었으며, 전후방 모두 내측부와 중간부위가 고응력이고 외측부로 이동할수록 저응력이 관찰되었다. 수핵이 없는 경우는 후방보다 전방부에 고응력이 집중되었으며 국소적으로 응력이 집중되는 양상을 보이고 있다. 2. 최대 굴곡위에서는 수핵의 존재에 관계없이, 전방보다 후방부가 고응력이 집중되었으며, 수핵 유무 비교시 수핵이 있는 경우가 없는 경우보다 전방이 저응력, 후방은 거의 동등한 응력 분포를 나타내었다. 응력 분포도의 분석에 의하면 전반적으로 균등한 응력 분포 양상을 나타냈다. 3. 최대 신전위에서는 수핵 유무에 관계없이 전방부에 고응력, 후방부에 저응력, 내측에 고응력, 외측은 저응력을 나타내었으며, 수핵이 있는 경우 없는 경우보다 고응력을 나타냈다. 4. 기립 중립위와 최대 굴곡위의 비교에서는 기립 중립위보다 굴곡시 수핵의 유무에 관계없이 전반적으로 후방부 응력이 2차 정도 현저히 감소하는 양상을 보이면서 비교적 균등한 응력 분포를 나타냈다. 5. 최대 신전위와 최대 굴곡위의 비교에스는 수핵 존재시 최대 신전위보다 최대 굴곡위에서 응력 분포가 전후방 모두 2차 정도 감소되고 수핵이 없는 경우는 최대 신전위가 굴곡위보다 응력이 전후방 0.5차 정도 감소되었다.

  • The manipulations are the main therapheutic procedure of Chuna. Manipulation is the essential procedure of Chuna theraphy. On the basis of touch parts and motion changes, each elementary manipulation is divided into Stimulating Manipulations (reflexional manipulations) and Mobilizing Manipulations. Objectives: This study were advanced so as to know Chinese Chuna Manipulations especially on Herniated Nucleus Pulposus. Methods We Investigated Chinese medicine paper about Chinese Chuna Manipulations on Herniated Nucleus Pulposus between 1996 and 1999. Results. Chinese Chuna theraphy, Pressing Manipulations and Thrusting-Wrenching Manipulations are mostly used on Herniated Nucleus Pulposus, and Chinese Chuna theraphy carrys out Traction, Injection. Chinese medicine. Acupuncture side by side. Conclusions: Chinese Chuna theraphy uses not only Mobilizing Manipulations, but also Stimulating Manipulations whereas Korean Chuna theraphy chiefly uses Mobilizing Manipulations.

  • Purpose: We attempt to assess the differences in the degree of lumbar lordosis in patients with lower back pain caused by the herniation of the nucleus pulposus and in normal people (divided into male and female groups). Methods: This study was conducted with 14 patients (7 males, 7 females) diagnosed with, and being treated for, lumbar herniated nucleus pulposus and 14 normal people (7 males, 7 females). In order to examine the degree of lumbar lordosis in these subjects, hip flexor lengthening tests were conducted and the lumbar curves were measured in three postures (supine, sitting, and prone) and the results were compared. Results: The measured values of the curves for the standing and prone postures showed statistically significant differences between the normal group and the patient group, between the normal male group and the male patient group, and between the normal female group and the female patient group (p<0.05). Conclusion: The measurement method that uses flexible curve rulers in the standing or prone postures can be usefully utilized in assessing the lumbar lordosis of patients with lumbar herniation of the nucleus pulposus.

  • The aim of this study was to report on the resorption of herniated nucleus pulposus following acupotomy treatment. Two patients were treated with acupotomy which included integrative Korean Medicine treatment, for either cervical, or lumbar herniated nucleus pulposus. Magnetic Resonance Imaging was used to produce images before and after (several months) treatment. The Numerical Rating Scale scores and Range of Motion were used to assess the patients at admission and discharge. In both cases, substantial resorption of the respective herniated disc was observed in the magnetic resonance images, with a decrease in the Numerical Rating Scale score. Range of Motion improved in 1 case. This study shows that acupotomy treatment may be a clinically effective treatment for herniated nucleus pulposus resorption and pain relief.

  • We experienced a case of osteoid osteoma in thoracic vertebra accompanied with herniated nucleus pulposus during the management of back pain. A 32 year old male patient with herniated nucleus pulposus complained of back pain and radiation to right leg. Lumbar epidural block with 1% mepivacaine 5 ml was performed for pain control and it relieved the radiating pain. However patient continued to experience severe exacerated back pain at night which responded to aspirin. Therefore we performed further examination for existence of disease of the spine and diagnosed osteoid osteoma in the right pedicle of T12 vertebra. In conclusion, we recommend physicians when evaluating patients with back pain to be congnizant of possible existence of neoplastic disease of the spine and incorporate it in differential diagnosis.

  • Objectives : Herniation of Nucleus Pulposus(HNP) of Lumbar is the most important that causes low back pain. The aim of this study is to compare several therapies about Lumbar spine Hearniated Nucleus Pulposus in oriental Medecine which are Bee-venom Acpuncture and Ouhyul Herbal Acpuncture. Methods: Subjects of this research were 60 inpatients complaining Herniation of Nucleus Pulposus, and who were diagnosed as bulging disc, disc protrusion or extrusion with CT & MRI. 20 patients in each, 3 groups; Acpuncture therapy only, Bee-venom Acpuncture, and Ouhyul Herbal Acpuncture, were divided and the conclusions for treatment are as follows. Results : 1. Regarding alleviation of pain by VAS, Ouhyul Herbal Acpuncture Group III showed significant decrease of VAS in the early period of admission(5days), while Bee-venom Acpuncture Group II showed higher score of VAS compared to Acpuncture therapy only Group I. 2. On contrary, in the latter period of admission($5{\sim}9days$), Bee-venom Acpuncture Group II showed significantly higher rate of improvement than the other groups. 3. On the 9th admission day, Bee-venom Acpuncture Group II and Ouhyul Herbal Acpuncture Group III showed higher improvement than Acpuncture therapy only Group I. Between group II and III, Group II showed higher improvement rate. Conclusions : In this study, there were different effects among three groups according to period of treatment. Further study on various traatment for Herniation of Nucleus Pulposus required.

  • There is a variety of therapeutic modality for herniated nucleus pulposus. Recently the low level laser has come into use for treatment for it. We treated two patients suffered from herniated nucleus pulposus of the central type of $L_{3,4}$ level, with He-Ne, $CO_2$ and Ga Al As laser simultaneously daily under hospitalization. In order to determine the efficacy of treatment, we used the "visual analogue scale" and its improvement rate. The results were as follows; Case I complained of gait disturbance, and hypoesthesia on the lateral side of the left lower leg, as and as low back pain. At the 15th day after treatment, VAS improvement rate was 40%, and the gait disturbance and hypoesthesia were markedly improved. 35th days after tratement, VAS improvement rate was 80%. Case II complained only of low back pain. At the 15th day after treatment, the VAS improvement rate was 68%, and at 20 days after treatment it was 84%. We sugsest that, using the low level laser for treatment of herniated nucleus pulposus increased the cartilage entrophism, and inhibitory effects of the inflammatory materials such as acid glycosaminoglycan by its anti-inflammatory and analgesic effects.

  • Purpose: This study was evaluated the effects of nucleoplasty and chemonucleolysis, as interventional treatments for herniated intervertebral disc disease, on spinal tissues. Methods: Nucleoplasty using plasma beam and chemonucleolysis with collagenase were conducted on the spinal motion segments that were dissected from of human cadaver spine under fluoroscopic guidance. After the procedure, the intervertebral discs were transected, and the changes in gross findings were examined. Subsequently, the influence of the procedure on the nucleus pulposus, annuls fibrosus, and endplate was analyzed through a pathologic examination. Results: Nucleoplasty was confirmed to eliminate the local range of tissues in nucleus pulposus according to the procedure tract and to not affect other tissues. In chemonucleolysis, we found that collagenase diffused from the surgical site within the nucleus pulposus and was not present in the annulus fibrosus and endplate. Conclusions: The clinically-used interventional treatments that were investigated here were not found to do not cause additional damage to areas other than those targeted.

  • The Intervertebral disc is a composite structure made up of the nucleus pulposus (NP) core surrounded by the multi-layered fibers of the annulus fibrosis (AF)[1]. Water is drawn into the NP by the presence of hydrophilic proteins called proteoglycans [2]. The AF, with successive layers oriented in alternating directions, surrounds the NP. These layers are placed under tension as the NP absorbs water and swells [3]. (omitted)
