Abstract :
A 5-year-old male mixed-breed dog was brought to the Central Veterinary Hospital with pain and abnormality in the right front limb. Upon physical examination of the limb, inward deviation of the front paw and instability of the carpal joint were diagnosed. Radiographic studies confirmed the absence of the antebrachial bone and dislocation of the carpal joint. Longitudinal pre-axial hemimelia was diagnosed. Surgical correction of this abnormality was recommended to the owner, but they refused the surgery and only accepted the recommended care instructions. During fetal development, errors may occur that lead to the formation of structural or functional congenital abnormalities, which present abnormally at birth. Congenital abnormalities can affect the entire body or specific parts of different body systems. If a limb is congenitally underdeveloped or incompletely formed, this defect can manifest in various forms, ranging from the absence of a single structure to the partial or complete absence of the limb. This clinical case was a form of hemimelia, a congenital abnormality characterized by the complete or partial absence of one or more bones. One type of this abnormality is longitudinal hemimelia, defined by the congenital absence of one or more bones along the pre-axial (medial) or post-axial (lateral) side of a limb. Another type of hemimelia is intercalary hemimelia, in which all or part of the middle bones of a limb are absent, but the upper and lower parts remain intact.
