Laminite crônica em equídeos da raça crioula: características clínicas e radiográficas

Abstract

This study aimed to analyze the profile of Criollo horses affected by chronic laminitis brought to the Equine Center of Veterinary Hospital from the Federal University of Santa Maria from March 2010 to October 2011. Medical records, the daily clinical evaluations and radiographic studies were used. The results obtained were analyzed by Pearson correlation. Data were computed for nine horses, five females and four males mean age 8,56 ± 5,88 years and 104.22 ± 91.73 days of hospitalization. The females were 55.56% (5/9) of the cases, while the stallion 44.44% (4/9). 22.22% (2/9) had laminitis in all four limbs, while 77.78% (7/9) presented only in the forelimbs. Laminitis of 1/9 were due to endotoxemia (11,11%), 44.44% (4/9) related to Equine Metabolic Syndrome and 44.44% (4/9) of unknown cause. Radiografic study 66.67% (6/9) showed sinking of third phalanx 20mm. Only 11.11% (1/9) of the animals presented unilateral sinking of the third phalanx. The sinking of the bony column was not correlated (p>0,05) with the degree of lameness. Of the nine animals in this study 66.67% (6/9) showed 5.5 ° rotation in at least one member. The degree of rotation was positively correlated (p<0,05) with the degree of lameness. Two patients (22.22%) required tenotomy of the deep digital flexor. Supportive therapy, intensive nursing care, corrective trimming and shoeing provided a high survival rate after discharge so that the animals could be kept without medication to maintain comfort.
