This study aims to describe a novel design of an acrylic external skeletal fixator system for stabilizing epiphyseal/metaphyseal fractures with or without articular involvement and evaluate its efficiency in 13 cases. Client-owned five cats and eight dogs with epiphyseal/metaphyseal fractures were included in this study. Cross pins with or without a transcortical pin were included in "J" shaped acrylic ESF, and this novel technique was called the Tie-cross ESF. The functional use of the extremity was evaluated, and the joint range of motion was assessed and compared with the contralateral side. Radiographs were evaluated for bone healing and possible complications. The time of the first use of the extremities changed from the day of surgery to the second day. Fracture healing occurred in 35-69 days, and ESFs were removed. No persistent lameness was observed, and total functional recovery was provided in all cases. Fixation of epiphyseal and metaphyseal fractures can be challenging, especially when it involves the articular surface. Including cross-pins in an acrylic ESF (Tie-cross ESF) is useful and can be considered an alternative technique for the stabilization of these fractures. This technique encourages the patient to use the extremity during the fracture healing and enables joint functions; therefore, additional physical therapy will not be necessary.
