Abstract:
The diaphyseal nutrient foramina of 123 pairs of radius and 112 pairs of ulna from local Chinese adult skeleton collection have been observed. Their length, diameter and circumference were measured.The nutrient foramina on the shaft of radius, in longitudinal direction, located near the junction of the upper and middle thirds, and those of ulna located a little lower.In horizontal direction, the nutrient foramina chiefly concentrated on the anterior surface. But there were more foramina situated on the interosseous crest or posterior surface on radius than that on ulna.100 cases of nutrient artery to radius and ulna have been dissected on preserved cadavers. The length, diameter and distance from the origin of the artery to the level of elbow joint have been measured. The nutrient arteries to radius and ulna may have. various origins. They mostly arise from anterior interosseous, common interosseous, ulnar, ulnar recurrent and rarely from radial, median or dorsal interosseous arteries.The course and distribution of the nutrient arteries in the bone marrow cavity were examined on X-ray films prepared from injected radio-opaque specimens.
