Objectives : There are many kinds of method to evaluate neural decompression during operation. They are direct visual and manual inspection, intraoperative ultrasound, endoscope, intraoperative computed tomography and intraoperative myelography. We used intraoperative myelography to evaluate the proper decompression of neural elements during the decompressive surgery. Methods : We injected 10-20cc of nonionic water-soluble contrast materials through direct puncture site of exposed dura during operation or lower lumbar level or lumbar drain inserted preoperatively. 12 patients were included in this study. They were 7 patients of centrally herniated lumbar disc disease, 1 patient of multiple lumbar spinal stenosis, 2 patients of thoracic extradural tumor and 2 cervical fracture & dislocations. Results : 5 of 12 patients showed remained neural compression through intraoperative myelography, so they were operated further through other approach. Myelographic dye is heavier than CSF, so the dependent side of subarachnoid space was visualized only. In one case, CSF leakage through hemovac was detected, but it was treated only bed rest for 5 days after hemovac removal. Conclusion :Intraoperative myelography is an effective method to evaluate neural decompression during spinal surgery. This technique is easy and familiar to us, neurosurgeons.

Objectives : This study aims to educate clinical doctors of the valuable practice of Manipulative Therapy(MT) as an opportunity for evidence-based medicine. Consequently it also serves to review the effectiveness and safety of MT. Methods : The literature studies of overseas were done by Cochrane Library and Medline website; those of domestic researches were completed by utilizing the sources which are gained from KERIS, KISS, DBpia, Kisti, and domestic institutes related with MT. Results : Eight papers related to the effectiveness of MT were published in South Korea, which concluded with the positive effects of MT. None of them are, however, well-designed randomized controlled trials(RCT). On the other hand, fifteen cases of nine articles indicate the adverse reaction of MT, and numbers of the researches in overseas revealed the side effects of MT in order of cervical, lumbar, and thoracic vertebrae. A vascular adverse reaction such as vertebral and carotid artery dissection was a highly reported cervical adverse reaction; in the thoracic and lumbar regions, neurological adverse reaction in terms of disc hemiation was frequently discovered. Conclusions : Henceforth, highly qualitative studies are required developing the effective outcomes and preventing any possible complications of MT. Therefore, systemic curriculums in institutions and sufficient clinical training in the filed are strongly recommended.

A 69-year-old man was admitted to our hospital for deep vein thrombosis, and he had experienced two episodes of left leg swelling: one happened after an 11 hour-air trip from Europe in June 2007, and the other developed 3 days after an operation for a herniated lumbar disc in July 2007. We treated him for a deep vein thrombosis of the deep femoral vein after admission. However, we arrived at the final diagnosis of angioleiomyosarcoma after the operation for the tentative diagnosis of deep vein thrombosis. We removed the firmly engorged deep femoral vein on the second operation. We report here on a case of angioleiomyosarcoma that arose from the deep femoral vein.

Idiopathic hypertrophic spinal pachymeningitis (IHSP) is a rare inflammatory disease characterized by hypertrophic inflammation of the dura mater and various clinical courses that are from myelopathy. Although many associated diseases have been suggested, the etiology of IHSP is not well understood. The ideal treatment is controversial. In the first case, a 55-year-old woman presented back pain, progressive paraparesis, both leg numbness, and voiding difficulty. Initial magnetic resonance imaging (MRI) demonstrated an anterior epidural mass lesion involving from C6 to mid-thoracic spine area with low signal intensity on T1 and T2 weighted images. We performed decompressive laminectomy and lesional biopsy. After operation, she was subsequently treated with steroid and could walk unaided. In the second case, a 45-year-old woman presented with fever and quadriplegia after a spine fusion operation due to lumbar spinal stenosis and degenerative herniated lumbar disc. Initial MRI showed anterior and posterior epidural mass lesion from foramen magnum to C4 level. She underwent decompressive laminectomy and durotomy followed by steroid therapy. However, her conditions deteriorated gradually and medical complications occurred. In our cases, etiology was not found despite through investigations. Initial MRI showed dural thickening with mixed signal intensity on T1- and T2-weighted images. Pathologic examination revealed chronic nonspecific inflammation in both patients. Although one patient developed several complications, the other showed slow improvement of neurological symptoms with decompressive surgery and steroid therapy. In case of chronic compressive myelopathy due to the dural hypertrophic change, decompressive surgery such as laminectomy or laminoplasty may be helpful as well as postoperative steroid therapy.

One of the most common sources of spinal pain syndromes is the facet joints. Cervical, thoracic, and lumbar facet joint pain syndromes comprise 55%, 42%, and 31% of chronic spinal pain syndromes, respectively. Common facet joint disorders are degenerative disorders, such as osteoarthritis, hypertrophied superior articular process, and facet joint cysts; septic arthritis; systemic and metabolic disorders, such as ankylosing spondylitis or gout; and traumatic dislocations. The facet pain syndrome from osteoarthritis is suspected from a patient's history (referred pain pattern) and physical examination (tenderness). Other facet joint disorders may cause radicular pain if mass effect from a facet joint cyst, hypertrophied superior articular process, or tumors compress the dorsal root ganglion. However, a high degree of morphological change does not always provoke pain. The superiority of innervating nerve block or direct joint injection for diagnosis and treatment is still a controversy. Treatment includes facet joint injection in facet joint osteoarthritis or whiplash injury provoking referred pain or decompression in mass effect in cases of hypertrophied superior articular process or facet joint cyst eliciting radicular pain. In addition, septic arthritis is treated using a proper antibiotic, based on infected tissue or blood culture. This review describes the diagnosis and treatment of common facet joint disorders.

A 40 year-old male patient admitted for dyspnea and edema of the lower extremities. A pulsatile abdominal mass with a bruit was palpable in the right lower quadrant. Four months previously, he had underwent left partial lam-inectomy ($L4{\sim}5$) and discectomy at the L4 level due to disc protrusion, Computed tomography showed an ilio-iliac AV fistula with pseudoaneurysm at the L5 level. Because massive bleeding occurred when the aneurysm was entered, we closed the aneurysm and performed resection and suture of the aorta and both iliac arteries very near the aneurysm. After exclusion of the arterial side, we performed reduction angioplasty at the aneurysm and aorto-biiliac reconstruction with an artifcial graft. Twenty-four months after operation, he is doing well and hasn't had any complications on the follow-up.

The Korean spine geometry and property data for researchers were made by KISTI and Catholic Institute for Applied Anatomy. We took whole spine CT, X-Ray, BMD scan for making high resolution cross-sectional spine images using more 20 donated cadavers(60 - 80 years). Then we constructed 3-dimensional volume model using serial CT images by Mimics software. The major morphometric parameters of vertebrae were measured. Mechanical motion and property data were obtained by the same cadavers using the DEXA for BMD and the spine simulator. The Korean spine geometry and property data could be used for research and development of medical device.

Purpose: To examine the relationship between the progression of a kyphotic deformity and the magnetic resonance imaging (MRI) findings in conservatively treated osteoporotic thoracolumbar compression fracture patients. Materials and Methods: This study categorized the patients who underwent conservative treatment among those patients who underwent treatment under the suspicion of a thoracolumbar compression fracture from January 2007 to March 2016. Among them, this retrospective study included eighty-nine patients with osteoporosis and osteopenia with a bone density of less than -2.0 and single vertebral body fracture. This study examined the MRI of anterior longitudinal ligament or posterior longitudinal ligament injury, superior or inferior endplate disruption, superior of inferior intravertebral disc injury, the presence of low signal intensity on T2-weighted images, and bone edema of intravertebral bodies in fractured intravertebral bodies. Results: In cases where the superior endplate was disrupted or the level of bone edema of the intravertebral bodies was high, the kyphotic angle, wedge angle, and anterior vertebral compression showed remarkably progression. In the case of damage to the anterior longitudinal ligament or the superior disc, only the kyphotic angle was markedly prominent. On the T2-weighted images, low signal intensity lesions showed a high wedge angle and high anterior vertebral compression. On the other hand, there were no significant correlations among the posterior longitudinal ligament injury, inferior endplate disruption, inferior disc injury, and the progression of kyphotic deformity and vertebral compression. The risk factors that increase the kyphotic angle by more than 5° include the presence of injuries to the anterior longitudinal ligament, superior endplate disruption, and superior disc injury, and the risk factors were 21.3, 5.1, and 8.5 times higher than those of the uninjured case, and the risk differed according to the level of bone edema. Conclusion: An osteoporotic thoracolumbar compression fracture in osteoporotic or osteopenic patients, anterior longitudinal ligament injury, superior endplate and intravertebral disc injury, and high level of edema in the MRI were critical factors that increases the risk of kyphotic deformity.
