Short and long term follow up of humeral condylar fracture type II treated by lag screw and anti-rotational pin associated to olecranon osteotomy

Humeral condylar fractures are relatively common in dogs and are most often associated with low-energy trauma, mainly affecting young animals. Anatomical reduction and rigid stabilization are mandatory to correct these types of articular fractures and achieve the main goals as early return of limb function, pain-free elbow movement, and prevent or at least reduce degenerative joint disease. Even with optimal anatomic reduction, surgical outcome complications associated to this type of fractures may be very common, giving this kind of osteosynthesis a reserve prognosis and making it challenging to the surgeon. In the case report, an adult mixed-breed dog, 3,9 kg, has fractured the lateral condylar portion of the left humerus after a 4 meters fall. Corrective osteosynthesis was performed using an association of a transcondylar lag screw and an anti-rotational pin through an olecranon osteotomy access. Monthly clinical and radiographic follow up were carried out with the intent to show bone healing evolution. Within 45 days consolidation of the fracture could already be seen. And after 180 days follow up, no signals of osteoarthrosis were found in the elbow joint, and the dog is fine, painless, has good weight bearing and optimal limb function.
