Objectives : This study aimed to introduce a new traction therapy and proposes that a new Chuna manual therapy technique could be implemented. Methods : The patient is placed in the prone position and their ankle is fixed to the fixing table. Next, clinicians contact on the vertebral spinal process above herniated disc region with the tissue pulled head part of scaphoid bone and the lower part of the pelvis is pulled horizontally to the foot. Conclusions : It was recently identified that traction while maintaining lumbar lordosis is more effective for lumbar disc herniation and is associated with fewer side effects. Chuna manual therapy also uses a technique of lumbar flexion-distraction manipulation to treat HIVD. further research is required.

Distant metastasis of squamous cell carcinoma from the anal canal is an uncommon event. However, hematogenous spread to the vertebrae may occur in the course of this disease. The route of metastasis from the anal canal seems to be Batson's vertebral venous system. A 52-year-old female patient presented with lower back and right leg pain of one-week history. She has undergone radiotherapy and chemotherapy for squamous cell carcinoma of the anal canal and then was followed by surgical resection. Three months later, magnetic resonance images of the lumbar spine disclosed a well-enhanced mass of L5 vertebral body compressing the thecal sac. Surgical decompression and biopsy were performed. Histopathological study confirmed carcinoma of the squamous cell origin. We report a ra re case of vertebral metastasis from squamous cell carcinoma of the anal canal with a pertinent review of literature.

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.

To examine among patients with vertebral compression fracture the extent to which signal-to-noise ratio (SNR) and Apparent Diffusion Coefficient (ADC) values at the lumbar vertebral compression fracture site vary on diffusion-weighted MR images according to varying b values on the 1.5T MR device. Diffusion-weighted MR images of 30 patients with compression fracture due to chronic osteoporosis who underwent vertebral MRI from Jan. 2008 to Nov. 2009 were respectively obtained using a 1.5-T MR scanner with the b values increased from 400, 600, 800, 1,000 to $1,200\;s/mm^2$. For diffusion-weighted MR images with different b values, the signal-to-noise ratio (SNR) was assessed at three sites: the site of compression fracture of the lumbar vertebral body at L1 to L5, and both the upper and lower discs of the said fracture site, while for ADC map images with different b values, the SNR and ADC were respectively assessed at those three sites. As a quantitative analysis, diffusion-weighted MR images and ADC map images with b value of $400\;s/mm^2$ (the base b values) were respectively compared with the corresponding images with each different b value. As far as qualitative analysis is concerned, for both diffusion-weighted MR and ADC map images with b value of $400\;s/mm^2$, the extent to which signal intensity values obtained at the site of compression fracture of the lumbar vertebral body at L1 to L5 vary according to the increasing b values were examined. The quantitative analysis found that for both diffusion-weighted MR and ADC map images, as the b values increased, the SNR were relatively lowered at all the three sites, compared to the base b value. Also, it was found that as the b values increased, ADC valueswere relatively lowered at all the three sites on ADC map images. On the other hand, the qualitative analysis found that as the b values increased to more than $400\;s/mm^2$, the signal intensity gradually decreased at all the sites, while at the levels of more than $1,000\;s/mm^2$, severe image noises appeared at all of the three sites. In addition, higher signal intensity was found at the site of compression fracture of the lumbar vertebral body than at the discs. Findings showed that with the b value being increased, both the signal-to-noise ratio (SNR) and Apparent Diffusion Coefficient (ADC) values gradually decreased at all the sites of the lumbar vertebral compression fracture and both the upper and lower discs of the fracture site, suggesting that there is a possibility of a wider range of applications to assessment of various vertebral pathologies by utilizing multi b values in the diffusion-weighted MRI examination.

Purpose: Continuous use of a smartphone increases the angle of forward bending of the user's cervical vertebrae, causing pain in the shoulders and back, including the thorax, lumbar region, and vertebrae. Although there are many studies on changes in the cervical spine due to smartphone usage, the changes in the shoulders, thoracolumbar spine, and pelvic have rarely been compared. The purpose of this study is to investigate the change in the spinal segments, shoulders, and pelvic when using a smartphone with both hands while in the standing position. Methods: This study was conducted on 35 adults in their twenties. The selection criteria for the subjects were limited to those in a similar age group, thus excluding posture differences according to age, and to those who did not have specific diseases or pain in the spinal and musculoskeletal system for 12 months prior to the study. In this study, we used a 3D spinal diagnostic imaging system (Back Mapper, Frickenhausen) to compare the changing conditions in each vertebral segment before and during smartphone usage with both hands while in the standing position. Posture differences according to smartphone usage were compared using the paired t-test for the motion of each spinal segment. Results: This study showed that the thoracic and lumbar angle increased posteriorly during smartphone usage (p<0.05). In addition, the anterior rotation angle of the shoulder bone significantly increased, but no significant difference occurred in the pelvic region. Conclusion: Based on the results of this study, smartphone usage with both hands while in the standing position showed that the spine, as a whole, forms a kyphotic curve. Therefore, we propose to present a postural guideline for correct smartphone usage, considering the change in each vertebral segment.

Background: This study aimed to compare pressure pain thresholds (PPTs) in the vertebral segments between patients with chronic lower back pain (CLBP) and healthy participants without back pain and to determine the correlation between vertebral bone-segment PPT and pain level, lower back pain dysfunction, and psychological status in patients with CLBP. Methods: The subjects of this study were 23 healthy adults and 23 adults with CLBP. PPT was measured in 23 spinal bone segments using a PPT device, and the CLBP group was subjected to a pain level test (NRS) and a psychological test using the Korean version of the pain catastrophizing scale (KPCS). The functional level was assessed using the Korean version of the Oswestry disability index (KODI). Results: PPTs of the spinal sclerotomes were significantly lower in patients with CLBP than in healthy participants. In the CLBP group, the composite score of lumbar PPTs showed a high correlation with the composite scores for all segments, but not with the pain level (NRS), KPCS score, and spinal sclerotome PPT. Moreover, PPT in the sacral sclerotomes showed a significant negative correlation coefficient with function, with a KODI score of -.462 (p<.01). Conclusion: In this study, PPTs in all spinal segments in patients with CLBP was significantly lower than that in healthy subjects. The PPTs of the lumbar region was significantly correlated with the PPTs of other spinal regions. Through this study, it was found that there were changes in PPTs in CLBP patients not only in the lumbar region but also in other spinal regions. This information should be considered during clinical treatment of patients with low back pain.

Direct anterior approach for lesions located anterior to the thecal sac is definitely superior to lateral or posterior approach in many respects. However, various anatomical obstacles and technical difficulties often hinder direct anterior approach. Thanks to ripe experience of retroperitoneal approach to the lumbar spine for anterior lumbar interbody fusion and total disc replacement, the authors could perform lumbar corpectomy and reconstruction by using midline retroperitoneal approach recently. During this approach, we repaired anterior longitudinal ligament also to reduce the risk of graft extrusion and to prevent erosion of vascular wall due to direct contact between metallic hardware, which was used for reconstruction of vertebral body, and major vessels.

Objective : Spondylothesis is a disease which sagittal facet of vertebral body's invariable alignment is being broken and vertebral body being pushed forward. Main pattern of spondylothesis is isthmic spondylothesis by isthmus defect or fracture, degenerative spondylothesis occurred by desiccated change of intervertebral disc or vertebral condyle joint's ligament. The purpose of this study is to assess the difference of the Pelvic angles, Lumbosacral angles, Pelvic tilt, and Lumbar lordotic angles of the spondylothesis patients. Methods : We analyzed the lateral view of lumbar spine of 49 isthmic spondylothesis patients, 45 degenerative spondylothesis patients and 26 patients who haven't been diagnosed as vertebra disease. We investigated each patient's pelvic angle, lumbosacral angle, pelvic tilt and lumbar lordotic angle. Results and Conclusion : 1. Pelvic incidence, in cases of degenerate spondylothesis patients, is higher than spondylothesis patients but shows less significance. On the contrary significance is higher than the group haven't been diagnosed as vertebra disease. 2. Lumbosacral incidence, in cases of isthmic spondylothesis patients, shows higher significance than degenerative spondylothesis patients and the group haven't been diagnosed as vertebra disease. 3 Pelvic tilt, in cases of degenerative spondylothesis patients, shows higher significance than isthmic spondylothesis patients and the group haven't been diagnosed as vertebra disease. 4. Lumbar lordotic angle, in cases of isthmic spondylothesis patients, shows higher significance than degenerative spondylothesis patients and the group haven't been diagnosed as vertebra disease. 5. Degenerative spondylothesis patient shows specific impression, a forwardly moved high femoral axial and as a result of large lumbrosacral angle and lumbar lordotic angle shows specific impression, an increased weight pressure on sacrum.

Objectives: Loss of lumbar lordosis causing pain and curvature of the vertebral skeleton to one side is a relatively uncommon disease. To our knowledge, successful treatment of loss of lumbar lordosis with any potentized homeopathic drug diluted above Avogadro's limit (that is, above a potency of 12C) has not been documented so far. In this communication, we intend to document a relatively rare case of loss of lumbar lordosis with osteophytic lippings, disc desiccation, and protrusion, causing a narrowing of secondary spinal canal and a bilateral neural foramina, leading to vertebral column curvature with acute pain in an adolescent boy. Methods: The patient had undergone treatment with orthodox Western medicines, but did not get any relief from, or cure of, the ailment; finally, surgery was recommended. The patient's family brought the patient to the Khuda-Bukhsh Homeopathic Benevolent Foundation where a charitable clinic is run every Friday with the active participation of four qualified homeopathic doctors. A holistic method of homeopathic treatment was adopted by taking into consideration all symptoms and selecting the proper remedy by consulting the homeopathic repertory, mainly of Kent. Results: The symptoms were effectively treated with different potencies of a single homeopathic drug, Calcarea phos. X-ray and magnetic resonance imaging (MRI) supported recovery and a change in the skeletal curvature that was accompanied by removal of pain and other acute symptoms of the ailment. Conclusion: Homeopathy can be a safe, much less expensive, non-invasive, and viable alternative for the treatment of such cases.
