The authors analized the 98 cases of cervical spine injuries without fracture or dislocation by hyperflexion/hyperextension of the neck. The peak incidence of the age was in the second to fourth decades(69.4%). There was a male preponderance with a sex ratio of. 1.8 : 1. Sources of trauma were motor vehicle accident, object falling on and motorcycle accident in the order of frequency. The common mechanisms of injury were flexion-extension, extension and flexion injury in the order of frequency. There were 10 cases of cervical cord injury without fracture or dislocation and operative management was given in 6 cases of them. The most common preexisting disease was congenital cervical stenosis. Surgical modality such as laminectomy, laminoplasty and anterior decompressive procedure made them improved. The authors discuss the mechanism of injury and surgical management of the patients with cervical cord injury in the absence of concomittent fracture or dislocation.

The authors described different type of aneurysms in the distal anterior cerebral artery(DACA), which is difficult to approach surgically. there are anomalies of distal anterior cerebral artery in about one fourth and narrow space, which made more careful surgical dissection. We experienced 7 cases of DACA aneurysm, 6 cases of which were treated surgically through the interhemispheric approach via the unilateral frontal paramedian craniotomy on the non-dominant side. Surgical results were anatomical complexities, modern microsurgical technique aided by microscope make the approach more exactly and safely.

A giant aneurysmal cerebral arteriovenous malformation in the left parieto-occipital region is described in a 4 year old child, including resolution of the alternating hemiparesis and left ventricular hypertrophy of the heart following successful removal of the malformation by microsurgical technique. This arteriovenous malformation has a large aneurysmal sac, 6x5x4cm, in size with several feeders from branches of the left middle and posterior cerebral arteries and drains directly into the straight sinus. So we have proposed to call it "a giant aneurysmal cerebral arteriovenous malformation".

Rupture of an intracranial dissecting aneurysm is a rare but dangerous event and are difficult to diagnosis and manage, and carry a high morbidity and mortality. The angiographic features typically showed fusiform dilatation and proximal and/or distal dilatation of the affected artery. Depending of location of dissection, surgical options are;ligation, trapping, or reenforcement of exposed abnormal portion of vessels. The authors report a case of nontraumatic dissecting aneurysm, stroke with subarachnoid hemorrhage(SAH) and the proximal porton of origin of PICA was treated with dlipping of vertebral artery proximal to dissecting aneurysm.

The authors describe 2 cases of multiple thoracic disc herniations in the level of T5~6, T6~T7, T7~8 and T8~9, T9~10, T10~11. Thoracic disc herniations is rare and occurs in less than 4% of all diseases. Moreover, multiple thoracic disc herniations is very rare and only 7 cases were reported in the literatures, which occurred at two levels in 6 cases and five levels in one case. The lesions were determined by thoracic CT myelogram and MRI study. A microsurgical posterolateral approach made them curative. Surgical instruments such as downbite curette and surgical microscope were essential for successful treatment.

Osteochondroma of long bone are common lesions : however spinal involvement may occur in 2.5% to 7% of all, and usually occurs from the neural arch of spinous process. Neurological complications are rare, occurring in less than 1% of patients of them. The authors report a solitary osteochondroma occurring in the lamina of C5, causing spinal cord compression.

The authors have performed simple CT-guided free-hand tumor biopsy. CT images and C-arm fluroscopy were taken to determine the coordinates of the target point, which was the center of the tumorous CT findings. This CT-guide stereotaxic approach for biopsy of intracranial tumors have the following advantages: 1) The procedure is simple and safe. 2) The operation can be performed under local anesthesia. 3) The operation can be performed without stereotaxic frame. 4) Tissue biopsy was taken on various sites of tumors. The authors have performed 4 cases as follow: 3 cases of anaplastic astrocytoma, 1 case of metastatic tumor. Neither mortality nor morbidity was noted.

OBJECTIVE: The purpose of this study is to elucidate the anatomic relationships between the uncinate process and surrounding neurovascular structures to prevent possible complications in anterior cervical surgery. METHODS: Twenty-eight formalin-fixed cervical spines were removed from adult cadavers and were studied. The authors investigated the morphometric relationships between the uncinate process, vertebral artery and adjacent nerve roots. RESULTS: The height of the uncinate process was 5.6-7.5 mm and the width was 5.8-8.0 mm. The angle between the posterior tip of the uncinate process and vertebral artery was 32.2-42.4degrees. The distance from the upper tip of the uncinate process to the vertebral body immediately above was 2.1-3.3 mm, and this distance was narrowest at the fifth cervical vertebrae. The distance from the posterior tip of the uncinate process to the nerve root was 1.3-2.0 mm. The distance from the uncinate process to the vertebral artery was measured at three different points of the uncinate process : upper-posterior tip, lateral wall and the most antero-medial point of the uncinate process, and the distances were 3.6-6.1 mm, 1.7-2.8 mm, and 4.2-5.7 mm, respectively. The distance from the uncinate process tip to the vertebral artery and the angle between the uncinate process tip and vertebral artery were significantly different between the right and left side. CONCLUSION: These data provide guidelines for anterior cervical surgery, and will aid in reducing neurovascular injury during anterior cervical surgery, especially in anterior microforaminotomy.
