Parachuting has become progressively a very popular recreational sports in foreign developed nations, and subsequently injury caused by it is getting more frighten and sometimes severe. Authors in this study clinically analysed 306 cases of parachuting injury who were treated at the department of orthopaedic sugery, C.A.F.G.H. during 3 years period from March, 19xx to February, 19 XX. There results were as followings: l. Of 306 cases, 268 had fracture, 38 soft tissue injuries. 2. Of 268 fracture cases, 208 cases had injuries in the lower extremity, 48 cases in trunk, 15 cases in upper extremity. 3. The most common associated injury was the head injury (26%). 4. The most common injured site was ankle and foot (57.5%), the next spine and pelvis (16.9%). 5. Through this study, it is said that parachuting is a dangerous sports, and the injury caused by parachuting may be largely preventable, if with adequate practical instruction, coaching and wearing protective garments.

Ankylosing spondylitis is an inflammatory disorder of unknown etiology that primarily affect, the spine, the axial skeleton, and the large proximal joints of the body with striking tendancy toward fibrosis with secondary ossification and ankylosis of involved joints. This study was carried out to analyse clinical manifestation, evaluate disease activity indicator and set up diagnostic work-up. 38 cases of ankylosing spondylitis were studied at Department of Orthopedic Surgery, Seoul National University from Oct. 1987 to Mar. 1989. Following results were obtained. l. Average age was 28.5 years and all patients were male. 2. Low back pain was the most frequent symptom(63%) and back stiffness was next(13%). 3. S-I joint change on x-ray was the most frequently found abnormalities(100%) and HLA B27 (+) was next(97%). 4. SI/S ratio was inversely correlated with duration of symptom and seems to be significant durng the early phase of disease. 5. As a disease activity indicator, CRP was more reliable than ESR during follow up.

BACKGROUND: The aim of this study was to compare the cardiovascular changes followed by laryngoscopy with the McCoy laryngoscope blade with those followed by laryngoscopy with the Macintosh laryngoscope blade. METHODS: Forty eight patients were randomly divided into two groups. Following induction with fentanyl 2 mcg/kg and thiopental 5 mg/kg, and muscle relaxation with vecuronium 0.1 mg/kg, the vocal cords were visualized with either the McCoy or the Macintosh laryngoscope blade, then tracheal intubation was performed. Heart rate and arterial blood pressure were measured just before and after laryngoscopy, and 1, 3 and 5 min later. RESULTS: There was a significant increase in both heart rate and arterial blood pressure after tracheal intubation using the Macintosh laryngoscope. Also, use of the McCoy blade resulted in a significant increase in both heart rate and arterial blood pressure. CONCLUSIONS: There was no significant difference on arterial pressure and heart rate to laryngoscopy and tracheal intubation with either the McCoy blade or the Macintosh.

We present a case of epidermodysplasia verruciformis a.ssociated with Bowen's disease. Patient was 33 year-old male and his skin lesions showed diffuse flat papules on face and neck, many brownish papules on trunk and papillomatous tumors also appeared un scalp and post auricular area, Skin biopsy findings from the flat papular lesion showed histopathologic features of verruca plana and from the papillomatous lesion showed the feature of Bowen's disease. Electron microscopic finding from the flat papular lesion showed marked aggregates of viral particles around the nuclei of epidermal keratinocytes.

Angiographic diagnosis of lesions of the posterior fossa requires detailed knowledge of the normal anatomy of both arteries and veins of the brainstem and cerebellum. For this perfuse we measured normal distribution of the vertebrobasilar vessels from three base lines namely clival line, Twining line and foramen magnum line. In the measurement are also included some of the methods which were published in the past. This paper is based on the results of the measurements on 18 cases of normal vertebral angiogram among 77 cases of serial vertebral angiography performed at Catholic Medical center from October 1972 to August 1975. The result obtained were as follows: 1) Distance from the most posterior portion of the pericallosal artery to the clival line is 6.55+/-0.68 cm. 2) Distance from the most posterior portion of the arcuate portion of the lateral posterior choroidal artery to the clival line is 5.16+/-0.61 cm. 3) Distance from the posterior portion of the quadrigeminal portion of the medial posterior choroidal artery to the clival line is 4.87+/-0.67 cm. 4) Distance from the most posterior portion of the distal segment of the medial posterior choroidal artery to the clival line is 4.47+/-0.49 cm. 5) Distance from the bifurcation portion of the basilar artery to the clival line is 1.22+/-0.26 cm. 6) Distance from the forward convexity of the basilar artery to the clival line is 0.15+/-0.11 cm. 7) Distance from the choroidal point to the clival line is 2.99+/-0.51 cm. 8) Distance from the posterior medullary portion of the PICA to the clival line is 2.58+/-0.45 cm. 9) Distance from the tuberculum sellae to the Torcular Herophilli(Twining line) is 10.96+/-0.52 cm. 10) Distance between the tuberculum sellae to the point on the Twining line crossed by a perpendicular line drawn from the choroidal point is 6.61+/-0.40 cm. 11) Distance from the superior portion of the anterior culminate segment of the superior cerebellar artery to the Twining line is 3.28+/-0.48 cm. 12) Distance from the supratonsilar portion of the PICA to the Twining line is 0.97+/-0.42 cm. 13) Distance from the colliculocentral point to the clival line is 3.74+/-0.37 cm. 14) Distance from the crural portion of the anterior pontomesencephalic vein to the clival line is 1.65+/-0.33 cm. 15) Distance from the crural portion of the anterior pontomesencephalic vein to the colliculocentral point is 2.51+/-0.35 cm. 16) Distance from the copular point to the clival line is 3.99+/-0.51 cm. 17) Distance from the copular point to the line drawn from the anterior margin of the foramen magnum is 1.63+/-0.38 cm. 18) Distance from the highest point of the lateral posterior choroidal artery to the Twining line is 4.74+/-0.37 cm. 19) Distance from the highest point of the medial posterior choroidal artery to the Twining line is 4.35+/-0.34 cm. 20) Distance between two bisected points of the anterior culminate segment of the superior cerebellar artery by a line drawn parallel to the Twining line at 1cm from the top of the anterior culminate segment is 2.86+/-0.29 cm.

We reviewed 9 cases of pyogenic spondylodiscitis following percutaneous endoscopic lumbar discectomy (PELD). Microbiologic cultures revealed 6 causative organisms. Five patients were managed conservatively and four were treated surgically. The mean follow-up period was 20.6 months and the average length of hospitalization was 24 days. Radiological evidence of spinal fusion was noted and infection was resolved in all patients. Although PELD is a safe and effective procedure, the possibility of pyogenic spondylodiscitis should always be considered.

Lumbar discal cyst is a rare cause of radiculopathy. Their exact pathogenesis and the optimal treatment modality remain unidentified. Depending on their location, discal cysts cannot always be easily identified intraoperatively. We describe 2 patients with discal cysts and introduce an intraoperative discography technique for discal cyst location. Both patients were treated with surgical excision; with intraoperative discography, the cystic lesions could easily be detected and removed.

The possible causes of Brown-Sequard Syndrome (BSS) have been frequently observed with spinal trauma and extramedullary spinal tumors, but the cervical disc herniation to cause BSS is rare. The authors present five cases of patients who were diagnosed with BSS resulting from cervical disc herniation, and the results of the literature in view of their distinctive symptoms and clinical outcomes. Postoperatively, the patients showed complete or almost complete recovery from their motor and sensory deficits. On the basis of our cases, it is important to diagnose it early by cervical magnetic resonance imaging, especially in the absence of the typical symptoms of cervical disc herniation or other obvious etiology of extremity numbness. Immediate surgical treatment is also essential for a favorable functional neurological recovery.
