Fragmented coronoid process and incomplete ossification of the humeral condyle in a rottweiler.

Abstract

To describe incomplete ossification of the humeral condyle and fragmentation of the medial coronoid process in a Rottweiler. Clinical report. A 4-year-old sexually intact male Rottweiler. Physical examination, radiography, and computed tomography of both elbow joints were performed initially. Drill holes were made across the humeral condyle to promote ossification. Radiography and computed tomography were repeated 14 weeks later. Radiography was repeated 15 months later. A mild intermittent lameness remained. Preoperatively a radiolucent line was present across the right humeral condyle. This radiolucent line remained unchanged 14 weeks after drill holes were made across the condyle. Incomplete ossification of the humeral condyle is present in Rottweilers. Incomplete ossification of the humeral condyle is present in Rottweilers and may coexist with fragmentation of the medial coronoid process in that breed. The radiographic diagnosis may be difficult because precise positioning is required to see the area of incomplete ossification. Computed tomography may be required to confirm the presence of incomplete ossification of the humeral condyle. Drilling holes across the humeral condyle does not appear to lead to union of the area of incomplete ossification.
