Background: The congenital flexural deformity is common in cattle, often affecting the metacarpophalangeal joint of thethoracic limbs. The deformity may be mild, moderate, or severe, and the therapy depends on the limbs degree of flexionand the affected joint. In severe deformities, tenotomy of the flexor tendons and desmotomy of the suspensor ligament isrecommended. However, this surgical technique may not be sufficient to promote limb extension, and other interventionsmay be necessary. Thus, the purpose of this report is to describe a technique to correct severe flexural deformities of themetacarpophalangeal joint in calves.Case: A 3-month-old, female, Dutch-bred calf weighing 46 kg was referred for treatment of congenital flexural deformity.On attendance, the patient presented severe deformity in the right thoracic limb and mild in the left thoracic limb both at theheight of the metacarpophalangeal joints. During palpation it was possible to notice that the flexor tendons were contractedin both limbs. Radiographic exams were performed to rule out the presence of other diseases, confirming the diagnosis offlexural deformity. The patient was referred to surgery to correct the anatomical anomaly. The animal was submitted to general anesthesia and placed in right lateral decubitus. In the left thoracic limb, an incision was made in the medial region ofthe metacarpal bone, the tissues were divulsioned until the superficial digital and deep digital flexor tendons were exposed;these structures were sectioned with a scalpel, and the limb was extended, returning to the standard anatomical position. Inthe right thoracic limb, the same procedure was performed, but during the limb extension test, we observed that the limbremained flexed, we then followed with a second incision and section of the deep...(AU)
