Plain-English summary
A group of dogs with elbow joint problems underwent a surgical procedure called bi-oblique dynamic proximal ulnar osteotomy to improve their joint alignment. After 12 weeks, CT scans showed that the surgery successfully increased the space in the elbow joint, which is a good sign that the joint was healing properly. While some measurements indicated changes in the joint structure, the overall results suggest that the surgery helped correct the elbow incongruence. This means that the dogs likely experienced improved joint function and comfort after the procedure.

Abstract
OBJECTIVE: To evaluate radioulnar joint modification using computed tomography (CT) after bi-oblique dynamic proximal ulnar osteotomy (BODPUO). STUDY DESIGN: Clinical study. ANIMALS: Dogs (n = 18, 26 elbows) with elbow incongruence treated by a single surgeon with BODPUO. METHODS: Radioulnar space measurements were performed on transverse, frontal, and sagittal CT projections preoperatively and after radiographically determined osteotomy healing. RESULTS: Three transverse plane measurements were statistically different than preoperatively at 12 weeks after the surgery demonstrating divergence of the lateral coronoid region of the radial incisure of the ulna from the radial head. None of the other measurements within the elbow were statistically different, but measurements of the radioulnar space at the level of the osteotomy site documented a statistically significant caudal tipping of the distal extent of the proximal ulnar segment. CONCLUSION: CT measurements documented a significant increase in radioulnar joint space at the mid-coronoid level, at the level of the base of the medial coronoid process, and at the level of the lateral coronoid process. This corresponds to cranially directed rotation of the medial coronoid process around the proximal radial epiphysis. A tendency for cranial tilting of the medial coronoid process was observed, which was confirmed by statistically significant caudal tipping of the distal extent of the proximal ulnar segment.
