Morphological and morphometrical study of the fore limb bone of common eland (Taurotragus oryx)

This research paper presents a comprehensive morphologic and morphometric analysis of the forelimb bones (scapula, humerus, radius, and ulna) of the common eland (Taurotragus oryx) that are facing the threat of extinction. The study aims to contribute essential anatomical and clinical data, as well as facilitate biomedical research and educational endeavors. Bone specimens sourced from the Bangladesh National Zoo, Dhaka, were subjected to a standard hot water maceration technique, followed by sun-drying and treatment with ۵% hydrogen peroxide. The scapula displayed a distinct triangular flat shape with a well-developed spine, and demarcating supraspinous and infraspinous fossae. Scapular weights were recorded at ۶۹۸ gm (right) and ۷۱۸ gm (left). The humerus, a robust and elongated bone measuring an average of ۳۵.۹ cm, exhibited a compressed cylindrical diaphysis and expanded epiphyses, with the right humerus weighing ۹۴۴ gm and the left, ۱۰۱۶ gm. Notably, the humeral shaft displayed distinct regional compressions and expansions. The radius, slightly oblique and broader than the ulna, demonstrated cranial-caudal flattening. In contrast, the ulna, the longest bone at an average of ۴۱.۶ cm in the forearm, displayed distinct anatomical features. These findings offer valuable insights for comparative anatomical investigations within this taxonomic group and hold significance for clinical applications and educational purposes.
