Reconstruction of Femur Non-Union in a Small Breed Dog: Application of Titanium Bio-Scaffold, rh-BMP, and Double Plating

Non-union fractures represent a challenge in veterinary orthopedics. Traditional methods, such as autograft are commonly used but come with limitations, including donor site morbidity and restricted graft material. In this case report, a 2-year-old Maltese presented with a viable hypertrophic non-union femoral fracture. Surgical intervention involved the application of a custom-de-signed 3D-printed titanium scaffold combined with rh-BMP2, a potent osteoinductive agent, to stimulate bone regeneration. Additionally, a double plating technique was utilized to ensure robust mechanical stabilization. Postoperative assessments through radiographic imaging and computed tomography (CT) scans taken 6 months post operation confirmed successful bone union. This case highlights the advantages of integrating cutting-edge technology, such as 3D-printed titanium scaffolds, rh-BMP2 and double plating into non-union fracture management protocols.
