Partial unilateral radial hemimelia in feline / Hemimelia parcial unilateral de rádio em felino

ABSTRACT

Background: Hemimelia is a rare anomaly in which one of paired bone is congenital or partially absent. The etiology may be related to genetic and/or environmental factors. Clinically is observed the angulation of the affected limb, resulting in functional limitations as angular deformity, lameness and decreased range of motion. The diagnosis is based on clinical findings and radiographic examination that detects the complete or partial absence of the affected bone and angular deviations. We aim to report a case of a partial unilateral radial hemimelia in a feline diagnosed at the Veterinary Hospital of the Federal University of Mato Grosso (HOVET-UFMT). Case We attended at the HOVET-UFMT a two years old, feline, female, domestic short hair, presenting as a complaint the presence of a friable mass in the oral cavity for a year and a deformity in the left forelimb since birth, showing swallowing difficulties, lameness and difficulty support. On clinical examination, we obeserved the left forelimb flexed and deviation in the medial direction, shortening of the limb, no crepitation during handling and evident lameness. Radiographic examination in the craniocaudal and mediolateral projections of the thoracic limbs revealed the partial absence of the radius with just a trace of the proximal radial epiphysis, shortening and a marked ulnar curvature, producing a significant deviation [...]
