A tibial plateau fracture was first described in the literature by Thamhayn, in 1852. It is a fracture of the proximal end of the tibia, usually involving an articular surface. The fracture is regarded as serious as it involves a major weight bearing joint and loss of function results in a high percentage disability of the extremity. Of the tibial plateau fractures treated at Hanyang University Hospital between June 1972 and August 1979, the 44 cases that could be followed for three months to two years have been analysed according to its cause, classification, treatment and result. Open reduction is indicated in anyone of or a combination of the following deformities as shown by roentgenograms: 1. a vertical depression in the plateau of greater than eight milimeters; 2. a horizontal displacement of the lateral or medial condyle of greater than four milimeters; 3. valgus or varus instability of the knee one or more milimeters in excess of that of the uninjured knee. Manipulation under anesthesia with skeletal traction is indicated in severe comminuted fracture that it is difficult to reduce with internal fixation, and open fracture that it is inevitable to delay operation. Plaster immobilization is indicated in the remaining situations except those of open reduction and skeletal traction. Anatomical considerations and a clinical end-result study of the 44 fractures emphasize the vulner-ability of the lateral tibial plateau to a valgus force on the extended knee. Among the 44 cases twenty-two (50 percent) were treated by plaster immobilization, 2 (4.5 percent) by skeletal traction, and 20 (45.5 percent) by operation. Thirty-nine cases (88.6 percent) out of 44 revealed the rating of “ACCEPTABLE” according to Hohl and Luck criteria.

BACKGROUND AND OBJECTIVES: Stroke onset is known to vary by several factors. Although it has been known that stroke may develop most frequently in the morning, its association with the type of activity has quite rarely been described. METHODS: We prospectively investigated by interview the time of and the activity during or before the onset of stroke in patients with acute cerebral infarction from Aug. 1995 to Mar. 1996. The activities were subdivided into basal metabolic rate state, sedentary, light, moderate, and heavy movements based on the caloric expenditure. RESULTS: One hundred-twenty five patients were enrolled. The time of day when ischemic stroke most frequently occurred was from 8:00 AM to noon. The type of activity was significantly associated with stroke onset in that it developed most commonly during and just after sleep or resting. The relationship between the onset of stroke and such patterns of onset time and the activity was found only in the atherothrombotic infarction, but not in the other stroke types. CONCLUSION: We demonstrated that stroke has clear diurnal variation. Our observations also suggested that the activity may be significantly associated with stroke onset. These findings may be useful for better understanding of the pathogenesis and prevention of ischemic stroke.

OBJECTIVE: This study is aimed to evaluate the various clinical characteristics, prognostic factors, and the treatment results in epidural hematomas on posterior cranial fossa. METHODS: Thirty-two patients with posterior fossa epidural hematomas(PFEDH) were managed in our institute from 1992 to 2001. In the same period, 414 patients with traumatic epidural hematomas were surgically treated and among these, 28 cases(6.8%) were PFEDH. Neurological state, findings of computed topography scans, and results of the treatment were evaluated in this study. RESULTS: The patients' ages ranged from 4 to 60 years, with predominance in adolescents. The male to female ratio was 3: 1. Twenty-nine patients presented with occipital trauma and twenty-eight cases had fracture in occipital bone. Fourteen patients suffered immediate unconsciousness and 6 patients with initial alert mentality experienced delayed progressive loss of consciousness. However, there were no changes on mentality in 12 cases. In 14 cases, the hematoma was localized exclusively within the posterior cranial fossa. In remaining 18 cases, the hematoma extended beyond the sinuses to the occipital area. In 13 cases, the amount of hematoma was increased in follow-up computed tomographic scan. All patients, managed with surgery or conservative treatment(4 cases), survived with a good recovery. CONCLUSION: The most important prognostic factor is prompt surgical evacuation of hematomas. For attaining good result, earlier diagnosis with consecutive computed tomographic scans are much important.
