“…The images for 3D CJF model production originated from the scanning of a natural bone, and production of the medical images (radiography) was carried out subsequently. Other studies have used the reverse approach, in that the 3D models were produced from medical images 8,25 .…”

“…The use of 3D printing in general veterinary medicine is already a reality. There have been great advances in the application of this technology in several areas, such as orthopedics 5 , ophthalmology 6 , diagnostic imaging 7 , treatment of large animals 8,9 , surgical planning 10,11 , and especially in the teaching of veterinary medicine 12 . In the latter, research has concentrated particularly on anatomy 13 and surgery 14 .…”

Purpose To develop 3D anatomical models, and corresponding radiographs, of canine jaw fractures.Methods A base model was generated from a mandibular bone scan. With this model it was possible to perform fracture planning according to the anatomical location.Results The 3D base model of the canine mandible was similar in conformation to the natural bone, demonstrating structures such as canine tooth crowns, premolars and molars, mental foramina, body of the mandible, ramus of the mandible, masseteric fossa, the coronoid process, condylar process, and angular process. It was not possible to obtain detail of the crown of the incisor teeth, mandibular symphysis, and the medullary channel. Production of the 3D CJF model took 10.6 h, used 150.1 g of filament (ABS) and cost US$5.83.Conclusion The 3D canine jaw fractures models, which reproduced natural canine jaw fractures, and their respective radiographic images, are a possible source of educational material for the teaching of veterinary medicine.

“…A similar case report described a 1.5-year-old donkey with severe angular and torsional valgus deformity of the right tarsus. CT imaging and 3D bone models were used to rehearse the surgery, and a successful closing wedge ostectomy was carried out (Radtke et al 2017).…”

Summary This case report describes the evaluation, surgical approach and outcome of an 8‐month‐old foal with severe angular limb deformities of both metatarsophalangeal joints (MTPJ). Radiography and computed tomography (CT) were used to diagnose a windswept deformity of the hindlimbs with associated bilateral physitis. The orthopaedic surgery was planned and rehearsed using three‐dimensional (3D) bone models. A bilateral closing wedge ostectomy was performed on the distal MtIII, and 3.5 mm LCP® medial distal tibia plates were used bilaterally for osteosynthesis. Even though convalescence was prolonged and complicated by partial unilateral implant failure and osteoarthritis (OA), reduction of the deformities was successful and resulted in a sound foal.

“…On these models, the exact displacement OE/OO can be practiced hands-on and is nowadays strongly recommended in human surgery (Franklin et al 2017;Kwun et al 2017;Winer et al 2017;Lau et al 2018). Recently, reports of using this technique in veterinary medicine have been published (Radtke et al 2017;Oaxley 2018;Lindt et al 2022;Schweinsberg et al 2021).…”

Application of computed tomography and stereolithography to correct a complex angular and torsional limb deformity in a donkey

Abstract: CT imaging and stereolithography facilitated the evaluation and surgical planning of a complex limb deformity. This combination of techniques may improve the accuracy of the surgeons' evaluation of complex bone deformities in large animals, shorten operating times, and improve outcomes.
