We describe a case of complex, posttraumatic skull and orbital deformities that were evaluated and treated with advanced computer technology, including virtual surgical planning, three-dimensional (3D) modeling, and printed patient custom implants (PCI) fabricated by 3D printing. A 50-year-old man presented to our craniofacial referral center 1 year after failed reduction of complex left orbital, zygomatic, and frontal bone fractures due to a motorcycle collision. The patient's chief complaint was debilitating diplopia in all fields of gaze. On examination, he had left enophthalmos, left canthal displacement, lower eyelid ectropion, vertical orbital dystopia, and a laterally and inferiorly displaced, comminuted zygoma with orbital rim and frontal bone defects. The normal orbit was mirrored to precisely guide repositioning of the globe, orbital reconstruction, and cranioplasty. Preinjury appearance with normal globe position was restored with complete resolution of diplopia. Modern 3D technology allows the surgeon to better analyze complex orbital deformities and precisely plan surgical correction with the option of printing a PCI. These techniques were successfully applied to resolve a case of debilitating diplopia and aesthetic deficits after facial trauma. Further application of advanced 3D computer technology can potentially improve the results of severe orbital and craniofacial trauma reconstruction.

Objective The main purpose of this study was 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 Case report. Animals Client-owned dog. Results One dog with a closed, severely comminuted, distal femoral supracondylar and bicondylar fracture underwent a preoperative computed tomography scan. Three-dimensional CASP was performed using computer-aided design software. 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 were performed without complications. 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 anatomical 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.
