The purpose of this study is to investigate how the application of a Thorax belt affects the stability of the spine in subjects with a wide infra-sternal angle. A total of 15 subject with wide infra-sternal angle participated in the experiment. Active Double leg lowering and active one-leg raising were performed with or without a thorax belt. Two spinal stability tests (active double lowering and active one-leg raising) performed with or without thorax belt application showed significant differences between each condition. Based on the results of present study, the application of a thorax belt is considered to be an effective therapeutic tool that can stabilize the spine to subjects with abnormally increased chest cage and spinal or trunk instability.

Purpose: This study examined the effects of a weekly teriparatide on the change in vertebral compression ratio, back pain, and vertebral fracture healing in osteoporosis patients with vertebral compression fractured induced by low energy trauma. Materials and Methods: From January 2016 to December 2017, 57 patients with severe osteoporotic vertebral fractures with a T score of -3.5 or less were included in this study. The changes in the vertebral compression ratio, visual analogue scale (VAS), Oswestry disability index (ODI) for at least 6 months were examined. The morphology of bone marrow edema and the presence of intervertebral cleft, osteocalcin, and N-terminal telopeptide (NTx) were also investigated. Results: The mean compression ratio was 20% in the experimental group (teripratide group) at 3 months, and 38% in the control group. A significant difference in the compression ratio of the vertebral body over time was observed (p<0.05; t-test). A comparison of the compression ratio of the vertebral body with the follow-up duration in each group showed no significant increase in the, compression (p=0.063) in the experimental group and a significant increase in the control group (p<0.05). The mean time to reach the plateau of the compression rate was one month in the experimental group and three months in the control group. The VAS score in the experimental and control group was 0.39 and 1.07 points, respectively. The ODI score in the experimental and control group was 33.72 and 39.52, respectively. At the last follow-up radiographs, there were no cases with an intervertebral cleft (0%) in the experimental group and 1 case (2.2%) in the control group. A significant difference in the osteocalcin level was observed between the injury and 6 months after the injury (p=0.003). In addition, there was no significant difference in the NTx level between the injury and 6 months after injury (p=0.960). Conclusion: In vertebral compression fractures patients with severe osteoporosis, a weekly teriparatide can promote the union of fractures, prevent further collapse of the vertebral body, and reduce the back pain faster.

척추의 생체역학적 해석을 위한 유한요소기법을 이용한 컴퓨터 시뮬레이션은 척추의 손상에 대한 발생원인과 기전을 이해하고 치료의 효과를 예측하는 유용한 수단으로 기대되고 있다. 본 논문에서는 요추의 2차원 CT 영상을 이용하여 유한요소해석을 위한 척추의 3차원 모델링에 소비되는 많은 시간을 줄일 수 있도록 3차원 형상모델을 CT 형상 데이터와 형상변수를 이용, 각각 구현하는 과정을 자동화하여 이를 비교하였다.

본 논문은 척추 건강관리기의 구동을 위한 가변형 전원 공급장치에 관한 논문이다. 본 시스템은 의료용 및 척추 마사지를 위한 장비로서 인체에 접촉하는 경우가 많고 높은 안전성을 요구하기 때문에 안정적인 전원 공급이 필요한 시스템이다. 본 시스템을 구동하기 위해서 100W의 전원이 필요하여 비교적 간단하고 절연타입의 Forward Type의 토폴로지를 적용하여 시스템에서 요구하는 전원을 공급하도록 회로를 설계 하였으며, 이를 시스템에 적용하여 성능을 검증하였다.

In this study, we evaluated the technical characteristics and usefulness of diffusion-weighted magnetic resonance imaging for discrimination between benign and malignant vertebral fractures, for detection and differentiation of multiple myeloma or metastases, and for response monitoring in malignant vertebral lesions after anticancer drug therapy or radiation therapy.

Spinal epidural lipomatosis, which causes symptomatic compression of neural elements, is a relatively uncommon disease. Although it has been reported frequently in association with the administration of exogenous steroids, a few cases of epidural lipomatosis with no association to exogenous steroids, have been reported. Idiopathic spinal epidural lipomatosis may be a separate disease from that induced by steroid. Here, the authors present two cases of symptomatic epidural lipomatosis with no history of steroid-dependent diseases and review the relevant literature.

Some considerations were made concerning the variation in the number of vertebrae (except urostyle) of anchovies sampled from the south coast of Korea, mainly off the city of Chungmu. The some seasonal difference was evinced in the mean value of vertebrae of small sized fish only, and no other significant differences were observed such as for locality or fishing gears. It was concluded that the anchovies from the south coast of Korea might be devided into spring and summer hatching populations and that the seasonal variation in the number of vertebrae might be caused by the difference of water temperature during the spawning season.

Since the advent of pedicle screw fixation system, posterior spinal fusion has markedly increased This intemal fixation system has been reported to enhance the fusion rates, thereby becoming very popular procedure in posterior spinal arthrodesis. Although some previous studies have shown the complications of spinal instruments removal, i.e. loss of correction and spinal collapse in scoliosis or long spine fusion patients, there has been no study describing the benefit or complications in lumbar spinal fusion surgery of one or two level. In order to clarify the effect of removal of instruments on mechanical motion profile, we simulated a finite element model of instrumented posterolateral fused lumbar spine model, and investigated the change of mechanical motion profiles after the removal of instrumentation.

본 연구는 복식호흡을 병행한 척추 안정화 운동이 요통환자의 균형능력과 통증에 미치는 영향을 알아보기 위해 시행되었다. 20대 요통환자 18명을 대상으로 하였으며 실험군은 척추안정화 운동을 실시하는 동안 복식호흡을 함께 적용하였으며 대조군은 척추안정화 운동만을 시행하였다. 운동은 8주간 적용하였으며 운동 시작 전과 후에 오스웨스트리 요통장애지수 설문지를 사용하여 통증을 비교하고 BioRescue를 사용하여 신체중심이 이동한 길이와 면적을 측정하여 균형능력을 비교하였다. 실험결과, 두 그룹 모두 운동 후, 요통장애지수가 유의하게 감소하였으나 그룹간의 유의한 차이는 없었다. 신체중심이동면적 비교에서 실험군은 운동 후 유의한 감소가 있었으나 그룹간의 유의한 차이는 없었다. 신체중심이동길이의 비교에서 눈을 감은 상태에서 실험군은 유의한 차이가 있었으나 대조군은 유의한 차이가 없었으며 그룹간 비교에서도 유의한 차이가 있었다. 이러한 결과를 통해 요통환자에게 안정화운동과 복식호흡을 함께 병행하여 실시한다면 더욱 효과적일 것이라고 생각된다.
