Acta Anatomica Sinica 1955;0(03):-
The arterial supply of the human metatarsals in 90 lower limbs,ranging in age from newborn to87 years,was studied by perfusion method. The blood supply of the metatarsals is derived from the nutrient artery,the periosteal arteries,the epiphyseo-metaphyseal arteries and the pseudoepiphyseal arteries. The proximal and distal branches of the nutrient artery supply the inner two-thirds or three-fourths of the cortex. The periosteal arteries give off a few twigs penetrating into the cortex and supplying the outer one-third or one-fourth of the cortex. The radiate form epiphyseo-metaphyseal arteries derived from superficial plexuses in continuity with the periosteal networks on the shafts, supply the base of the first metatarsal, and the heads of the other four. The pseudoepiphyseal arteries, penetrating the non-articular areas of the bones, supply the bases of the second, third, fourth and fifth metatarsals and the head of the first. The sources of the nutrient arteries to the metatarsal vary with the different bone . The nutrient arteries to first metatarsal bone usually originate from the ramus plantaris profundus and the first plantar metatarsal artery, while the nutrient arteries to the other metatarsal bones mainly derive from the plantar metatarsal arteries, the plantar arch and its perforating branches. The clinical significance of the arterial distribution to the metatarsals is discussed.

Objective To provide an anatomic data of the lumbar isthmus, and to increase the fusion rate of the graft bone for spondylolisthesis treated with posterolateral spinal fusion and Steffee plate fixation. Methods The area and volume of the bone graft bed for posterolateral spinal fusion in the lumbar isthmus were studied on 30 dried specimens of adult lumbar spines from L 1 to L 5(a total of 150 lumbar vertebrae) with a vernier calipers, a goniometer and a graduate. Results The length of the superior edge of the isthmus gradually increased from L 1[(7.34? 1.15) mm] to L 5[(10.31? 1.89) mm], and that of its inferior edge progressively decreased from L 1[(6.63? 1.24) mm] to L 5 [( 4.73? 1.21) mm]. The superior edge of the isthmus was the thinnest at L 1[(1.85? 0.64)mm], and the thickness increased inferiorly from L 1[(6.57? 1.24) mm] to L 5[(7.57? 1.16) mm]. The medial and caudal inclination of the isthmus with respect to the pedicle gradually increased from L 1 (113.9?? 13.3? ) to L 5(119.1?? 13.5? ) medial inclination and from (101.2?? 9.5? ) at L 1 to (117.6?? 13.4? ) at L 5 caudal inclination, respectively. The length of the superior edge of the isthmus and the transverse diameter of the pedicle were positively correlated to the vertebral levels. The length of the inferior edge of the isthmus were negatively correlated to the vertebral levels. The dimensions of the graft bed area were postively correlated to dimensions of the graft bone volume. Conclusion The application of firm spinal internal fixation system with adequate graft bed area and adequate graft volume, the maintenance of close contact between the graft bed and the graft bone, and adequate period of postoperative stable contact of the graft in bed were the keys to enable reduction of the spondylolisthesis and to increase the fusion rate of posterolateral bone graft.

Microvascular architecture of the oviduct was observed by SEM in 20 adult female Wistar rats which were not pregnant. The oviduct was supplied by 2-4 tubal branches (0.2-0.3mm in diameter) which were derived from the ovarian artery. The tubal branches entered the wall of oviduct and divided into numerous meandering arterioles (0.02-0.07mm in diameter). Intrinsic microvasculature of the oviduct might be divided into three layers: (1) the subserosal vascular plexus which appeared tortuous and formed reticulate anastomosis, (2) a parallel branching vasculature in the muscle coat, and (3) the subepithelial capillary network. The latter arised from the arterioles which ramified terminally near the apex of mucosal folds and broke up into very dense capillaries. Subepithelial capillary density in the fimbriae was markedly higher than that in the isthmus and uterine part. Intrinsic venules of oviduct were less tortuous and less closely accompanied with the arterioles. In mesoviduct, veins were in closely accompanied with the corresponding arteries. In the wall of oviduct, some capillaries and venules drained to the small veins directly and vertically.
