Cisto subcondral em côndilo medial do fêmur equino: relato de caso

Abstract

The subchondral cysts of the medial condyle of the equine femur have a multifactorial etiology, most frequently affecting foals at the age of onset, but can be diagnosed in adult horses. This lesion is characterized by intermittent claudication, according to the level of exercise that the animal is undergoing, if it increases the effort and the frequency, surely the horse will manifest clinical sign. Radiography and ultrasonography are the complementary exams of greater application in the diagnosis of cystic lesions. There are two main therapeutic approaches, the conservative one, which consists of joint infiltration using corticosteroids associated with joint and invasive lubricants, which may be corticosteroid intralesional injection, arthroscopy debridement and transcondylar screw placement. The present study describes the occurrence of a subchondral cystic lesion in the medial condyle of the femur of a 9-year-old equine, who was treated through joint infiltration and showed clinical improvement, returning to sports successfully after 90 days of treatment.
