Abstract

A 15-month-old female Belgian Malinois presented with an inability to ambulate on its pelvic limbs after running away. Orthopaedic examination revealed painful stifles, crepitus and a bilateral lack of patellar continuity. Radiographs confirmed bilateral patellar fractures showing a similar fracture pattern on both sides, with three parts divided in the shape of a ‘Y’. Surgical treatment consisted of fracture stabilisation using pins and wires protected by a tibio-patellar prosthesis and type Ia external fixator. Bone healing occurred and a satisfactory level of function was observed at long-term follow-up. This report describes the original presentation of bilateral patellar fractures in a dog. The bilateral presentation and similar fracture pattern on both sides potentially support the notion that failure of the patellar secondary ossification centres to unite caused fragility of both patellae.
