LAMINITE EQUINA - RELATO DE CASO

Abstract

Equine laminitis is a condition of high clinical relevance, characterized by inflammation and destabilization of the laminae that support the distal phalanx, which may progress to rotation, sole penetration, and severe impairment of locomotion. Considering its multifactorial nature and the impact on equine welfare and performance, this study aimed to report a case of chronic laminitis in a Quarter Horse, highlighting the clinical, diagnostic, and therapeutic aspects involved. The work was conducted as a qualitative case study through clinical evaluation, physical examination, static and dynamic inspection, digital radiography, venography, and follow-up assessment. The theoretical framework was based on classic authors in the field of equine orthopedics, emphasizing anatomical, pathophysiological, and therapeutic aspects. Imaging findings revealed a 10° rotation of the distal phalanx in both forelimbs, confirming the chronic nature of the condition. Venography showed preserved vascular perfusion, a key factor for prognosis. Treatment combined non-steroidal anti-inflammatory drugs, acetylsalicylic acid, gastric protectants, corrective trimming, silicone pads, wooden orthotic support, and a nutritional planwith carbohydrate restriction. After approximately 50 days, significant clinical improvement was observed, including a reduction in lameness from grade 4 to grade 3, increased tolerance to hoof manipulation, and satisfactory progression of hoof conformation. Months after rehabilitation began, the horse resumed reproductive activity and showed improvement in body condition. Therefore, it is concluded that the effectiveness of chronic laminitis treatment depends on the integration of accurate diagnosis, individualized therapeutic interventions, appropriate nutritional management, and continuous monitoring. Accordingly, this case reinforces the importance of a multidisciplinary approach to promoting functional recovery and well-being in horses affected by the disease.
