ABSTRACT
This study was designed to study gross morphological and basic osteometric features of the digit bones of Chinkara. The osteometry were performed manually through a digital vernier calliper on twenty (20) adult Chinkara (10 each male and females). The digits of Chinkara in each limb comprised the lateral and medial proximal, middle and distal phalanx. The first two phalanges were long bones. The shaft of the phalanx proximalis (P1) was thick proximally than distally and slightly arched. The phalanx media (P2) was shorter in length than the proximal. Its proximal articular surface was divided into two glenoid cavities “axial and abaxial’ by a dorsopalmar ridge. The phalanx distalis (P3) was triangular, with four surfaces and six borders. The descriptive analysis indicates, no statistically significant (p>0.05) differences between the lateral and medial phalanges of all measured parameters. All the measured parameters for the digits of the forelimb were statistically significantly different (p>0.05) between male and female adult Chinkara except greatest Length (Lg) of the phalanx media of the forelimb. Similarly, significant differences (p>0.05) were present in all the studied parameters of the P1, P2 and P3 of the hindlimb except for maximum breadth of the shaft (Bs) of the P2.
