BACKGROUND: Fractures of the talus are relatively infrequently reported in small animals. Furthermore, talar neck fracture in cats seems to be very rare. This case report aims to consider the diagnosis, treatment, and a 7-month follow-up of a cat with a Hawkins type 3 talar fracture treated with a type 1b external skeletal fixator (ESF). Emphasizing on the complexity of the injury, considering treatment options and complications, and comparing them to previous reports on cats and humans. CASE DESCRIPTION: A 4.5-year-old mixed-breed cat was diagnosed with a Hawkins type 3 talar fracture. Additionally, there were considerations related to the collateral support of the hock joint. The fracture fragment, i.e., the talar body and parts of the neck, was reduced with pointed reduction forceps through a small medial insition. The fracture was then stabilized with a trans articular type 1b ESF. Based on radiographic fracture assessment, de-staging of the frame was done 8 weeks postoperatively. While complete frame removal was at 12 weeks postoperatively. Seven months after the fracture, the cat was minimally lame when walking, and there was a reduced range of motion in the hock joint compared to the contralateral joint. CONCLUSION: Based on this case and the four previous cases with talar neck fractures, we cannot conclude, but ESF seems to be a good solution, especially when considering the possibility of disruption to the collateral support of the hock joint in this case.
