The anatomy of the canine distal ulna was evaluated to determine its potential as a free vascularized bone graft. Twelve cadavers were studied by gross dissection and nonselective and selective angiography. The caudal interosseous artery consistently served as a source artery to the distal ulnar periosteal vasculature in all dogs. The diameters of the caudal interosseous artery and venae comitantes were large enough to permit microvascular anastomoses. Nonselective perfusions of the brachial artery demonstrated large barium-filled vessels within soft tissues surrounding the ulna with anastomotic connections between medullary and periosteal vasculature. Grafts selectively perfused through the caudal interosseous artery (periosteal circulation only) had barium-filled vessels within the muscular cuff, periosteum, cortical bone, and medullary canal of the ulna. A surgical approach to remove the distal ulna along with an intact musculoperiosteal cuff and its associated vasculature is described.
对犬尺骨远端的解剖结构进行了评估,以确定其作为游离带血管骨移植供体的潜力。通过大体解剖以及非选择性和选择性血管造影对12具尸体进行了研究。在所有犬中,骨间后动脉始终是尺骨远端骨膜血管系统的供血动脉。骨间后动脉及其伴行静脉的直径足够大,能够进行微血管吻合。肱动脉的非选择性灌注显示,尺骨周围软组织内有大量充满钡剂的血管,骨髓血管与骨膜血管之间存在吻合连接。经骨间后动脉选择性灌注的移植物(仅骨膜循环)在尺骨的肌袖、骨膜、皮质骨和髓腔内有充满钡剂的血管。本文描述了一种切除尺骨远端以及完整肌骨膜袖及其相关血管的手术入路。
