Fifty-two patients of meniscal injury were studied in the Department of Orthopedic Surgery, Seoul National University Hospital for 5 years and 6 months from January, 1973 to June, 1978. The results were as follows: 1. Male was more affected than female (M:F = 1.4:1). And the injury of meniscus was most frequently occurred in the age group between 11 and 30 years old (65.2%). 2. Thirteen patients denied the history of trauma (25.2%). 3. Over-all positive rate of Memurray sign was 85% and arthrography was 74%. 4. Lateral meniscus was more frequently affected than medial meniscus. The most frequent type of lesion was peripheral longitudinal tear (11 cases). Discoid meniscus was found in 14 patients. 5. In follow-up study, satisfactory results were obtained in 84.3%.

In order to compare the effects of the flexible external fixations with the rigid one on fracture healing, rabbits tibiae were fractured surgically and each fracture were immobilized with external devices using graphites (the group I), plastics (the group II) and stainless steel (the group III). At six weeks after fracture, clinical and radiological union rates in group I, II and III were 91% 73% and 60% respectively. The rabbits tibiae were load in 4-point bending test to determine the mechanical properties of the fracture healing. The means and standard errors of maximum bend moment of the fractured tibiae were 11. 30±2.33kg.f. cm., 8.55±2.02kg.f. cm. and 9.79±2.09kg.f. cm. in group I, II and III respectively. These data may suggest that a certain amount of the flexibility (ex, graphite) or motion is better than the rigidity (ex, stainless steel) in fracture healing by the method of the external immobilization).

Metric dimensions of skull of Korean adults were measured and the indices of each dimension were calculated to identify the morphological characteristics of neurocrania of Koreans in 97 cases. The results were as follows. The maximal anteroposterior length was 171.6±8.4 (149.0~191.0)mm and the maximal lateral length (maximal breadth) was 142.4±5.4 (128.0~155.0)mm. The horizontal cranial index was 83.3±5.0 and therefore the neurocrania of Koreans were classified to brachycranic type (rounded cranium). The auriculo-bregmatic height was 119.3±5.1mm and basio-bregmatic height was 140.5±4.9mm. The height-breadth index on the basis of the auriculo-bregmatic height was 98.5±3.6, and belong to medium skull. The height-length index was 81.8±3.8, therefore they belonged to high skull. Height-breadth index on the basis of auliculo-bregmatic height was 85.4±5.7, and belonged to medium skull, and the height-length index was 70.5±5.4 and belonged to high skull. In the case of mean height index, the auriculo-bregmatic height was 77.2±5.0 (high skull), basio-bregmatic height was 87.6±2.6 (high skull).
