Three-Dimensional Computer-Assisted Surgical Planning and Use of 3-Dimensional Printing in the Repair of a Complex Articular Femoral Fracture in a Dog

Objective: To describe the use and benefits of 3-dimensional (3D) computer-assisted surgical planning (CASP) and printing in a complex articular fracture repair in a dog.

Study Design: Clinical case report.

Animal: Client-owned dog.

Materials and Methods: One dog with a closed, severely comminuted, distal femoral supracondylar and bicondylar fracture underwent a preoperative computed tomography (CT) scan. Three-dimensional CASP was performed using computer-aided design software. The three-dimensional CASP allowed for visualization of the fracture fragments and virtual surgery, including reduction of the fragments and implant placement. A 3D model of the affected femur was printed, and a bone plate was pre-contoured to the model. Intraoperative fracture reduction and stabilization was performed without complications.

Results: Postoperative radiographs revealed successful execution of the planned procedure. Subsequent radiographs and clinical examination indicated that bone healing was achieved with return to normal function of the limb. Three-dimensional CASP and the printed 3D model allowed for improved understanding of the anatomic relationship between fracture fragments, preoperative implant selection, and contouring, and the ability to practice fracture reduction and implant placement preoperatively. The model was also used for client education, and to teach students and residents.

Conclusion: Three-dimensional CASP and printed models are valuable tools in the preoperative planning of complex fracture repairs, educating clients, and teaching students and residents.
