A 5‐month‐old female cria with body mass of 30 kg was referred to the Langford Vet farm animal practice for management of a left tibial eminence avulsion fracture. Preanaesthetic medication consisted of xylazine 0.3 mg/kg and butorphanol 0.2 mg/kg intravenously, followed by induction of anaesthesia with ketamine 4 mg/kg intravenously. Anaesthesia was maintained with isoflurane vaporised in oxygen. A multimodal analgesic approach consisting of an ultrasound‐guided sciatic and saphenous nerve block using a combination of 2 mg/kg of lidocaine and 10 μg/kg of detomidine and a continuous infusion of ketamine 25 μg/kg/minute were used. Total anaesthetic time was 375 minutes. The cria received paracetamol 5 mg/kg and flunixin meglumine 2 mg/kg intravenously in the postoperative period. The cria was weight bearing on the operated hind limb 3 hours post‐extubation. Intravenous meloxicam (0.5 mg/kg/day) was administered 24 hours postoperatively for 4 days. Amoxicillin 15 mg/kg intramuscularly every 48 hours was continued until discharge.
