[Studies on the development of fetus scapula].
Extract and measure the scapular every part from the fetus that was carried into Saga medical college, the data was processed statistically. Also, the morphological characteristic of scapula of the fetus was clarified by image processing that a computer is used. The result was as follows. A scapular morphological length and also height become big in proportion to the height of fetus. Index of height-length of a fetus was big compared with adult, this trend is remarkable especially in a early stage of development of a fetus. Spinal axis angle of a fetus was also bigger than that of adult and it remarkable differ from an anthropoid very small ane. In general, the scapular shape of a fetus was short length with wide-spreading side and this form resembles to scapula of Jomon period people. The width of cartilage part tend to decrease as ossification progress fast width-wise with growth. However, area of cartilage part tend to become big, because the growth of a cartilage part is going fast lengthwise.
