Clinical Analysis of Cervical Spine Injury

The authors reviewed the cases of 95 patients with cervical spine injury, 28 patients underwent surgery and the others were managed with conservative treatment. The results were summarized as followings; 75 patients were 20-29 years old(78.9%). 2) There was no seasonal frequency variation(p<0.01). 3) The most frequent cause of injury was motor vehicle accident. 4) The common mechanisms of injury were flexion-extension, extension and flexion. 5) High cervical injuries were 32 cases(33.7%) and mid-low cervical injuries were 63 cases(66.3%). 6) C2 type II fracure was the most frequent type of high cervical injury(43.7%). 7) Associated injuries were found in 29.5% of the cases. 8) There was no statistical significance in the difference between the Frankel's classifications(A, D, E) of operated and those of non-operative cases(P<0.01) .

A Clinical Analysis of 4 Cases of Arachnoid Cysts in Middle Cranial Fossa, Associated with Chronic Subdural Hematoma

Since the arachnoid cyst was first described by Bright in 1831, its natural histroy and exact incidence of arachnoid cyst associated with chronic ubdural hematoma were not well understood. Authors analyzed 4 cases of arachnoid cysts in middle cranial fossa, associated with chronic subdural hematoma. So, the following results were obtained : 1) Headche and vomiting were presenting symptoms and its symptomas were due to chronic subdural hematoma rather than that of arachnoid cyst 2) Trauma, though trivial, may have triggered the development of chronic subdural hematoma 3) All cases showed bony abnormality on plain skull X-ray. 4) CT scan is very useful for the demonstration of shape, extent of lesion, membrane enhancement, and communication between hematoma and arachnoid cyst. 5) Every case was type II arachnoid cyst. 6) Chronic subdural hematoma was most frequent intracystic type, showing rupture into the arachnoid cyst. 7) Sugery treating both the chronic subdural hematoma and arachnoid cyst produced good result.
