TENOSSINOVITE NA BAINHA TENDÍNEA SINOVIAL DIGITAL EQUINA: relato de caso

Abstract

The equine athlete demands from its musculoskeletal and joint system to achieve high performance and efficient results in the biomechanics of movement, enshrining itself in its race. Not only in the competitive aspect, your locomotor system plays a fundamental role in your social function and even in your wildlife. The anatomy of the limbs is made up of tendons, ligaments, musculature, joints and blood vessels. The soft tissues, due to their demand for physical activities, suffer damage to their long fibers causing inflammation in the tendon structure. The inflammatory fluid degrades the soft tissue because its physicochemical composition is harmful to the tissue. Primary pathological interference can consequently cause pathological interference secondary to its occurrence. Surrounding the tendons in the distal portion of the equine limb is a structure containing synovial fluid, called the digital synovial tendinous sheath, which surrounds the main flexor tendons of the equine limbs. When the anatomical structures of the equine locomotor system are not in homeostasis and intact, distinct pathologies involving these structures may occur. Tendinopathies, synovitis and tenosynovitis can be used as an example of the pathologies involved. This paper reports a clinical case of an equine animal named Zulu Shine, Female, 14 years old, Quarter Horse, Weight 492 Kg, coat Palomino Baio, Three Drums athlete, who entered the “Clínica Pro Equus – Equine Sports Medicine” on 07/14/2021 in the afternoon with clinical picture of lameness of the left pelvic limb. A clinical picture of tenosynovitis in the plantar region of the equine boletus. The definitive diagnosis was reached through detailed clinical examination and complementary radiographic and ultrasonography exams. The result of the ultrasound was the pathology called tendinopathy. The radiography showed a radiopaque aspect in a prime area of tendon and ligament structures, being an abnormal pattern for the given location. The diagnostic imaging result was primary tendinopathy of the superficial digital flexor tendon and secondary synovitis of the digital synovial tendinous sheath.
