Title: Advanced research to develop new safe arthrocentesis approaches to the carpal joint in the camel

Biography:

Dr. Aiyan holds a Ph.D. in Veterinary Applied Anatomy from Freie Universität Berlin, Berlin, Germany. Before Joining the Department of Veterinary Medicine, UAEU in February 2014, he was working as faculty member at Institut für Veterinär-Anatomie, FU, Berlin, Germany where he has been teaching several courses for undergraduate and postgraduate veterinary students, as well as conducting research in the field of veterinary anatomy. Dr. Aiyan’s current research is linked to the Arabian camel (Dromedary), which is a socially and economically important animal in the UAE. Considered unique and economically important ruminant animal in arid and semi-arid areas like here in UAE.

Abstract

The knowledge gap regarding the topography and anatomy of the dromedary’s carpal joint must be bridged to improve diagnostic and treatment procedures such as ultrasonography, arthrocentesis, and arthroscopy. Thirty-five distal forelimbs were harvested from 21 dromedaries and studied through gross dissection, casting, ultrasonography, and computerized tomography. Representative threedimensional models of the joint cavities, recesses, and pouches were obtained using various casting agents. The safety and feasibility of different arthrocentesis approaches were evaluated. This study provides a detailed description of dorsally located joint recesses and palmarly located joint pouches. The dorsomedial and dorsolateral approach is recommended for arthroscopy and arthrocentesis of the radiocarpal and intercarpal joint when the carpus is flexed. However, caution must be exercised during these approaches to prevent needle injury to the articulating cartilage. Caution is necessary to prevent the formation of inadvertent communication between the dorsally located tendon sheaths and joint cavities. Arthrocentesis via the lateral approach to the lateropalmar pouch is the most favourable approach for the radiocarpal joint. A subtendinous synovial bursa was found between the lateropalmar pouch of the radiocarpal joint and the extensor carpi ulnaris muscle. The subtendinous synovial bursa must be considered during the lateral arthrocentesis approach. The palmar approach is not recommended for arthrocentesis due to the high risk of injury to nerves, veins, and arteries located palmarly.
