Summary A 4‐year‐old Arabian mare was presented for evaluation of a suspected right tarsal luxation. Radiographs of the affected area revealed a tarsocrural joint luxation with an associated fractured lateral tibial malleolus. Under general anaesthesia, the fractured lateral malleolus was surgically removed via an arthrotomy and the luxation reduced. A full‐limb fibreglass cast was then placed. Recovery from anaesthesia was assisted with a tail rope. The limb was immobilised for 8 weeks with a cast. The mare made a good recovery and was used as a broodmare 18 months later, despite osteoarthritis affecting the joint.
