Purpose: To explore the clinical characteristics of bone metastasis (BM) in a large sample of preliminarily diagnosed nasopharyngeal carcinomas (NPCs). Methods: The sample consisted of 1,031 patients diagnosed with NPC at first visitg clinics between October 1989 and June 2012. Several parameters including metastasis locus, T/N staging, diagnosis, therapy and prognosis of BM were analyzed retrospectively. Results: In 70 patients who had been preliminarily diagnosed with BM, the incidence of BM in N0, N1, N2 and N3 stage was 5.7%, 17.2%, 50.2%, and 25.7%, respectively, while the incidence in T0, T1, T2 and T3 stage was 0%, 23.8%, 47.6% and 28.6% respectively. BM occurred in most common in vertebral column, rib, sternum, ilium and femur. Positive rate of Epstein-Barr virus antibody was 77.6%. The median survival time was 12 months. Conclusion: The incidence of BM in NPC preliminarily diagnosed is about 7% and it is related to N classification but not T classification.

Objectives The present study retrospectively investigated clinical outcome of patients with structual scoliosis during Chuna treatment. Methods : The study population consisted of 34 patients(14 patients of adolescent and 20 patients of adult) who were diagnosised as scoliosis with radiological finding. All patients were treated with Chuna treatment, and after treatment, evaluated with radiological measurement by calculating the scoliosis correction angle from the Initial and follow-up spine AP and lateral views. Also the evaluation of clinical outcome was done twice pre and post treatment during this study. Results : The results were summarized as follows ; 1) The 85.3 percent of patients complained physical pain. and adult group had various painful lesion compared with adolescent group. 2) Adult group had treated $18.0{\pm}7.2$ times and adolescent group treated $13.5{\pm}5.7$ times with Chuna treatment. 3) Scoliotic angle is reduced in 92.9 percent of adolescent group and had all of adult group after Chuna treatment, especially, statistically significance appeared in adult group. 4) Adult group was superior to adolescent group in correctability and scoliotic angle change. 5) Correction effect was better in the group which initial scoliotic angle was lessor, or had more time of treatment. 6) According to grade of vertebral body rotation, scoliotic angle is larger and correctability was lower. Conclusions : Chuna treatment was efficacious against scoliosis. And it is necessary for adolescent scoliosis patient to be more carefully treated and observed.

Intracranial hypotension is a benign disorder characterized by orthostatic headache. It is caused by CSF leakage, therefore its treatment of choice has been epidural blood patch when initial conservative treatments were not effective. We would like to report a 26-year-old patient with recurrent orthostatic intracranial hypotension in spite of the successful epidural blood patch several times. Her headache was caused by myelography 8 month ago. Cisternography showed a CSF leakage at the level of L1 vertebral body. Headache was resolved completely after epidural blood patch and then recurred 3 times several months after blood patch. Now, she is free from headache for 5 months after last blood patch.

Objective : Posterior vertebral translation as a type of spondylolisthesis, retrolisthesis is observed commonly in patients with degenerative spinal problems. Nevertheless, there is insufficient literature on retrolisthesis compared to anterolisthesis. The purpose of this study is to clarify the clinical features of retrolisthesis, and its developmental mechanism associated with a compensatory role in sagittal imbalance of the lumbar spine. Methods : From 2003 to 2012, 230 Korean patients who underwent spinal surgery in our department under the impression of degenerative lumbar spinal disease were enrolled. All participants were divided into four groups : 35 patients with retrolisthesis (group R), 32 patients with simultaneous retrolisthesis and anterolisthesis (group R+A), 76 patients with anterolisthesis (group A), and 87 patients with non-translation (group N). The clinical features and the sagittal parameters related to retrolisthesis were retrospectively analyzed based on the patients' medical records. Results : There were different clinical features and developmental mechanisms between retrolisthesis and anterolisthesis. The location of retrolisthesis was affected by the presence of simultaneous anterolisthesis, even though it predominantly manifest in L3. The relative lower pelvic incidence, pelvic tilt, and lumbar lordosis compared to anterolisthesis were related to the generation of retrolisthesis, with the opposite observations of patients with anterolisthesis. Conclusion : Retrolisthesis acts as a compensatory mechanism for moving the gravity axis posteriorly for sagittal imbalance in the lumbar spine under low pelvic incidence and insufficient intra-spinal compensation.

Mucolipidosis (ML) is a kind of skeletal dysplasia. Characteristic X-ray findings of the bone may contribute to the early diagnosis and treatment of ML II/III. Skeletal radiographs show distinctive patterns at different ages: neonatal hyperparathyroidism, osteodystrophy (similar to chronic osteitis fibrosa cystica), and dysostosis multiplex. Patients with ML II/III show a mixture of osteodystrophic bone changes and atypical changes of dysostosis multiplex: proximal pointing of the metacarpals in the wrist, dysplastic changes in the lower third of the ilia, marked broadening of the ribs becoming oar-shaped, and beaking of the lower thoracic and lumbar vertebrae. In ML II, the osteodystrophy has clinical and radiographic features of neonatal hyperparathyroidism. In some neonatal subjects, chemical hyperparathyroidism is also demonstrated. After transient hyperparathyroidism in newborns, the progressive osteitis fibrosa cystica develops from 3-6 months of age. Patients with ML III show prominent skeletal involvement, particularly the destruction of vertebral bodies and the femoral heads. Intravenous pamidronate treatment is well tolerated, and it can produce clinical effects, with a reduction in bone pain and improvements in mobility in patients with ML III. In this review, the skeletal manifestations of ML II and III are investigated.

The pelvic girdle function as an integrated unit with all three bones moving at all three joints, are influenced by the lower extremities below and vertebral column and trunk above sacroiliac movements are caused by spinal motion, whereas iliosacral movements are caused by movements of the lower limbs. Concept of normal functional integration among the lumbar spine, pelvic and hip joint is basic to the understanding of dysfunction in this region and also functional movement of the lumbo-pelvic-hip region are part of the clinical examination, consequently the integrated biomechanics of these region need to be understood. The purpose of this review is to ascertain the integrated biomechanics among the lumbo-pelvic-hip complex by consideration of literature and to give sufficient information to be able to render accurate assessment and treatment for the syndromes described.

Osteochondromas are common, benign tumors in the long bones, but osteochondromas are rare in the vertebrae. Most vertebral osteochondromas arise from the cervical or upper thoracic spine. However, lumbar osteochondromas have rarely been reported. In this report, a rare case of a lumbar osteochondroma arising from the spondylolytic L3 lamina in a 57-year-old woman is presented. She also had a ruptured disc and lumbar canal stenosis at L4-5-S1. The osteochondroma was completely removed and a posterior lumbar interbody fusion and instrumentation were performed. Considering the rarity of osteochondromas in the lumbar vertebrae, especially the L3 vertebra, it is possible that the pre-existing lumbar spondylolysis or spondylolisthesis was one of the factors affecting the occurrence or progression of the osteochondroma.

We report a case of acute ischemic stroke involving both the anterior and posterior circulation associated with a persistent primitive trigeminal artery (PPTA), treated by endovascular revascularization for acute basilar artery (BA) occlusion via the PPTA. An otherwise healthy 67-year-old man experienced sudden loss of consciousness and quadriplegia. Magnetic resonance imaging showed an extensive acute infarction in the right cerebral hemisphere, and magnetic resonance angiography showed occlusion of the right middle cerebral artery (MCA) and BA. Because the volume of infarction in the territory of the right MCA was extensive, we judged the use of intravenous tissue plasminogen activator to be contraindicated. Cerebral angiography revealed hypoplasia of both vertebral arteries and the presence of a PPTA from the right internal carotid artery. A microcatheter was introduced into the BA via the PPTA and revascularization was successfully performed using a Merci Retriever with adjuvant low-dose intraarterial urokinase. After treatment, his consciousness level and right motor weakness improved. Although persistent carotid-vertebrobasilar anastomoses such as a PPTA are relatively rare vascular anomalies, if the persistent primitive artery is present, it can be an access route for mechanical thrombectomy for acute ischemic stroke.

The aim of this study is to compare reference levels for radiation dose in angiography and interventional radiology. Proposed reference levels for various procedures and classification of diseases are provided by fluoroscopy time and kerma area product(KAP) rate normalizing the body habitus focusing the cerebrum. Subarachnoid hemorrhage(SAH) represents the highest KAP-rates and aneurysm represents the lowest KAP-rates. According to these types of procedures, internal carotid artery(ICA), common carotid artery(CCA), and vertebral artery(VA) show the highest KAP-rates and guglielmi detachable coil shows the lowest KAP-rates. Therefore, the present study can suggested reference levels for patient radiation dose and is expected to be further useful in the field of radiation dose education and management of angiography and interventional radiology.

The most common deformity of the sternum is the depression deformity, variously calid pectus Excavatum, funnel chest, schwusterbrust, trichterburst, thorax en entonnoir. During the period 1983 to 1991 a total of 15 cases of funnel chest were treated surgically at Department of Thoracic Surgery, Hanyang University Hospital. The age at the time of operation ranged from 4 to 26 years 73.3 percent of the patients were under 12 years of age They all had symptoms of feeling Inferiority about chest deformity. The concavity on the funnel chest varied in its Extent, and the severity, which was measured by water volume filled into it, varied from 45ml to 100ml. We have Experienced 15 cases of pectus Exc-avatum with several operative method, i.e., Ravitch operation in 2 cases, Taguchi operation in 3 cases[using by Both IMA], Adkins operation in 5 cases, Modified wada operation [sternal costal cartilage Elevation Technique] in 5 cases. After surgery, follow up vertebral Index showed 44%, preoperatively and 29% postoperatively, average decrement of 15%. We Reported 15 cases of funnel chest and the surgical results of thease cases were satisfactory Except one case of Ravitch operation.
