Background: Femoral capital physeal fractures occur in young animals and are generally associated with trauma. They have apoor prognosis and surgical therapy is the most indicated. There are few studies describing surgical treatment and postoperative results, so the objective of the present report was to present the first case in Brazil of a colocefalectomy for the treatmentof femoral capital physeal fracture in a young pony, the post-surgical and the results obtained with the technique employed.Case: An 18-month-old pony, male, not castrated, , weighing 136 kg was referred to the Veterinary Hospital of the FederalUniversity of Paraná (HV-UFPR) with a history of trauma for 4 days. On physical examination, the animal presented lamenessgrade 5 of the right pelvic limb, shortening and lateral deviation of the limb, crackling and painful sensation on abduction, andslight atrophy of the gluteal muscles on the affected side. In the radiographic examination, a femoral capital physeal fracturewas found in the oblique ventro-dorsal projection. Once the diagnosis was performed, a colocefalectomy was realized, as thepatient is a light and short horse. The patient underwent general anesthesia and was placed in the left lateral position. The accessto the coxofemoral joint was made through the lateral face of the right hindlimb. The muscles of the region were incised anddeviated, so a partial myotomy was performed in the deep gluteal and vastus lateralis. This procedure allowed to visualize thefracture, where the head of the femur remained congruent to the acetabulum.
