Evaluation of distal femur fractures in cats by hybrid external fixator

Abstract

In this study, clinical and radiological findings obtained from the treatment of distal femur fractures in cats with hybrid external fixator were evaluated. A total of 10 cats of different ages, breeds and genders with clinically diagnosed femur fractures were used as research material. In the study, hybrid external fixators consisting of circular and linear fixators were used as osteosynthesis material. Closed reduction and external fixation methods were used in 2 cases diagnosed with closed fractures, while limited open reduction and external fixation methods were used in 8 cases diagnosed with open fractures or excessive dislocations. In the radiological examination findings, it was determined that fracture consolidation started on the post-operative 7th day in 9 cases and on the 10th day in 1 case, respectively. Fracture healing was completed in 4 weeks in 2 cases, in 5 weeks in 2 cases, and in 6 weeks in 6 cases (osseous callus was detected). Fixators were removed one week after healing was completed in all patients. In the study, soft tissue complications such as edema in the extremities in 3 cases, mild pin infection in 3 cases and open wounds in 4 cases were determined. However, it was observed that these complications did not adversely affect the recovery time. As a result, with the data obtained from the study, it was concluded that the distal femur fractures in cats of the age and weight scales examined in the study can be successfully treated with the hybrid external fixator system.
