A female dog presented with non-weight bearing lameness with an open fracture of the right forelimb. The fracture site had a 40 mm-long defect. A segmental bone defect (SBD) was treated with bone transport osteogenesis (BTO) by using a dynamic circular external skeletal fixator (CESF). After 63 days of BTO, a minimally invasive plate osteosynthesis (MIPO) was applied because of non-union at the docking site. BTO using the dynamic CESF method can be used successfully to restore a bone defect. The MIPO technique during the consolidation period is an alternative method to decrease complications and increase patient quality of life.
