| Description | Surgical treatment of advanced degenerative and posttraumatic osteoarthritis of the wrist is usually the only solution for restoring function in a damaged joint. Knowledge of the wrist vascularization is essential for surgical approaches and techniques. The radial-based dorsal capsulotomy is commonly used approach to the radiocarpal joint, when the incision is made along the radiocarpal and the intercarpal ligaments. The aim of our study was to provide detail description of arteries supplying dorsal portion of the radiocarpal joint capsule in relation to incision used in the dorsal capsulotomy. The study was performed using macro- and micropreparation techniques and radiological methods. The anatomical study was based upon analysis of fresh cadavers uppers exrtremities, amputated at the level of the forearm. The radial artery, anterior interosseous interosseus artery and the ulnar arteriesy were cannulated and injected by colored silicon rubber (Wacker Elastosil M4511), followed by macroscopical and microscopical dissection. Digital subtraction angiography (DSA) was used to visualize the vascular system of the wrist. The dorsal portion of the radiocarpal joint capsule receives blood supply from three dorsal transverse arches formed with anastomosis terminal branches of the anterior interosseous interosseus artery and radial arteriesy, minority from the ulnar artery. This arrangement was confirmed with DSA. We found that majority of arteries supplying dorsal portion of the radiocarpal capsule come from the radial artery. Based on these results it seems that classical capsulotomy might affect blood supply of the radiocarpal joint capsule. |
