We investigated the detailed extraosseous and intraosseous vascular anatomy of the distal radius and ulna in 55 pairs of canine forelimbs. Ten specimens were used for compartment identification. One hundred specimens were investigated after intra-arterial injection with red latex or Batson's compound. The extraosseous vascular network, including the nutrient artery location, was studied by delicate dissection and soft tissue digestion. Two superficial and 4 deep arteries were found on the dorsal aspect, with constant relationships to the retinaculum. On the palmar aspect, bony nutrient vessels rose from the branches of the radial artery (descriptive anatomy). The vascular supply of the canine distal forelimb was very consistent and enabled the design of 5 vascularized pedicle bone grafts similar to those described in humans (applied anatomy). These reverse-flow pedicle grafts may be placed in the carpus, allowing the canine forelimb to serve as an experimental model for the study of vascularized carpal bone grafting.

我们对55对犬类前肢的桡骨远端和尺骨远端的详细骨外和骨内血管解剖结构进行了研究。10个标本用于肌间隔识别。100个标本在动脉内注射红色乳胶或巴特森氏化合物后进行研究。通过精细解剖和软组织消化来研究骨外血管网络，包括滋养动脉的位置。在背侧发现了2条浅动脉和4条深动脉，它们与支持带的关系恒定。在掌侧，骨滋养血管起源于桡动脉分支（描述性解剖学）。犬类前肢远端的血管供应非常一致，从而能够设计出5种与人类描述相似的带血管蒂骨移植（应用解剖学）。这些反流带蒂移植可置于腕关节，使犬类前肢成为研究带血管蒂腕骨移植的实验模型。（《手外科杂志》2000年；25A:34 - 45。
