A patient is presented with a cervical spinal cord transection which occurred after a motor vehicle accident in which the air bag deployed and the seat belt was not in use. The patient had complete quadriplegia below the C5 level and his imaging study showed cervical cord transection at the level of the C5/6 disc space with C5, C6 vertebral bodies and laminar fractures. He underwent a C5 laminectomy and a C4-7 posterior fusion with lateral mass screw fixation. Previous reports have described central cord syndromes occurring in hyperextension injuries, but in adults, acute spinal cord transections have only developed after fracture-dislocations of the spine. A case involving a post-traumatic spinal cord transection without any evidence of radiologic facet dislocations is reported. Also, we propose a combined hyperflexion-hyperextension mechanism to explain this type of injury.

The vertebral pedicle is an important structure used as an implant site for spinal instrumentation surgery. Since precise anatomical knowledge of lumbar pedicles in vivo is essential for risk - free surgery, we analyzed Korean vertebrae with radiologic imaging techniques. The authors analayzed 500 pedicles from L1 to L5 vertebrae with computerized tomograms (CT) and simple radiograms taken from patient free of vertebral abnormality. Five morphometric parameters: transverse pedicle width, transverse pedicle angle, sagittal pedicle width, sagittal pedicle angle depth to anterior cortex were measured. The transverse diameter and angle of pedicle increased gradually from L1 to L5, while the sagittal diameter and angle decreased from L1 to L5. The depth to anterior cortex from posterior elements was longer along the pedicle axis than along axis parallel to midline.

Congenital intraspinal epidermoid tumors, while rare, do occur ; that they are related to spinal puncture is less well understood. This article describes the case of a 10 year-old boy with intraspinal epidermoid tumor, who five years previously had undergone lumbar puncture. A striking clinical features of this case is pain in the lower extremity. In this report, we review the literature and discuss the probable developmental mechanism of such tumor.

Spontaneous intracerebral hemorrhage is one of the most devastating forms of cerebrovascular disease in the field of neurosurgery, and is most frequently associated with the hypertension in the distribution of the penetrating vessels, or can be secondary to other factors, like aneurysm, arteriovenous malformation, glial tumor, metastasis, infarction, anticoagulation therapy, coagulation disorders such as leukemia or thrombocytopenia. Although many cases of recurrent hypertensive intracerebral hemorrhage have been reported, bilateral simultaneous hemorrhage has not been reported. The authors report a case of bilateral simultaneous hypertensive intracerebral hemorrhage in a 62-year-old male, which was treated by conservative management.

The occurrence of cerebellopontine angle(CPA) medulloblastoma is a rare phenomenon. This article describes the case of a 30-year-old man who presented with headache, nystagmus and cerebellar dysfunction of one month's duration. The tumor arose from the left flocculus or adjacent cerebellar hemishere and projected into the cerebellopontine angle. We review the literature and discuss the clinical characteristics and pathogenesis of CPA medulloblastoma.

Results from lumbar disc operation in general are favorable in 70% to 90% of patients. The rate of necessary reintervention of the primary discectomy, however, may be as high as one fifth of cases even though diagnostic and technical standards have been improved. The purpose of this study was to analyse the reasons for failure of primary discectomy and which factors might have influenced the outcome of revisions in 53 patients with failed back surgery syndrome from the years 1989 to 1993. Mean follow up duration was 11.4 months with range of 1 to 69 months. Before revisions, all patients had one or more lumbar disc operations in whom disabling pain, neurologic deficits, and/or lumbar instabilities have been persisted or newly developed. The most common intraoperative findings of patients with revision were recurrent or persistent disc material(35.9%) followed by incomplete decompression from previous operations(24.5%), and disc lesions at new level(11.3%). In overall, 77.3% of total patients showed satisfactor y results(fair, good, and excellent) but this figure drops to 39.6% when those with at least good or excellent outcomes are only considered as definitively improved. Moreover only 22.9% good results were obtained among 35 patients with those less than 6 months of symptom duration. As for the total number of operations undertaken, it can not be conclusively stated due to small numbers in each categories, but less favorable results have been observed in those with more than one revisions. The factors predicting good outcome from revisions in our series were:1) greater than 6 months of pain relief after primary operation, 2) sciatica more prominent than lower back pain, 3) fewer operations.

Paragangliomas of the orbit are extremely rare. A case of 43-year-old woman who presented with left exophthalmus of 1 month duration is described. The patient underwent surgery with gross total removal of the tumor and relief of her initial chief complaint of exophthalmus. We review the literature and discuss the clinical features and the pathogenesis of orbital paraganglioma.

OBJECTIVE: Whereas fusion with pedicle screw fixation has shown satisfactory clinical results, solid fusion has been reported to accelerate degenerative changes in adjacent unfused levels. The purpose of this study was to evaluate the effect of bone/ligament/bone integrity after subtotal or total laminectomies on the development of adjacent segment instability (ASI). The hypothesis that total laminectomy would increase ASI more than would subtotal laminectomy was analyzed. Material and METHODS: This is a retrospective study of 316 patients who were treated with posterior fusion and pedicle screw fixation between 1996 and 2001. After attempts to review all 316 patients and radiologic files, 36 patients who were diagnosed with ASI were carefully reviewed, including follow-up periods of 2-8 years. The medical records were carefully reviewed for recurrence of low back pain or neurologic symptoms after a period of postoperative relief, and the radiologic files were evaluated to determine instability. All patients had undergone single-level or multilevel instrumented posterior lumbar interbody fusion for intractable pain related to degenerative conditions of the spine. RESULTS: Patients over the age of 60 were at a higher risk of developing clinical ASI however,fusion length, level and gender were not associated with ASI. The ASI was noted to occur most commonly in the cranial segment prior to fusion. CONCLUSIONS: This study revealed more frequent ASI after total laminectomy than after subtotal laminectomy, especially in elderly patients. The ideal procedure will be one combining maximal canal and foraminal decompressions with minimal resection of bony structures and supporting ligaments.

SAPHO syndrome is an acronym for an increasingly recognized syndrome of synovitis, acne, pustulosis, hyperostosis, and osteitis. Most of the previously reported case are from Japan and Europe. The authors report a case of SAPHO syndrome in Korean female who presented with extrasternal neurologic symptoms. A 60-year-old female with thoracic and right chest wall pain presented with the sternocostoclavicular hyperostosis, and recurrent aseptic osteitis. Previously, she had hystrectomy and thyroidectomy due to uterine malignancy 25 years ago. Also, she started to take medications for palm and sole pustulosis 7 days prior to admission. Through evaluation of clinical, radiological, serological studies, studies was done along with bone needle biopsy for the biological reassessment. The hyperostosis was found in the pedicles of thoracic 8, 9, 10 vertebrae and sternoclavicular joint. Radio-isotope bone scan showed an accumulation of tracer in thoracic vertebra. The bone biopsy from these site showed increased osseous turnover, thickening of trabeculae accompanied by mild acculuation of granulation tissue and round cell infiltration, compatible with mild chronic inflammation with marrow fibrosis. The patient showed good response to conservative management. The authors report a case of SAPHO syndrome with thoracic radiculopathy. It is considered that SAPHO syndrome is related to spondyloarthropathy, and appears to have benign disease process with good prognosis.
