“…Numerous human and veterinary surgical studies have reported the use of 3D plastic models as surgical guides to use intraoperatively. 14,15,23,24 The 3D-printed specific guide permitted rapid, safe and accurate placement of implants. 15,23,24 In our study, only the size of the 3D model and the impact of the autoclave on it were evaluated.…”

Objectives The main purpose of this study was to determine the reproducibility and accuracy of a three-dimensional (3D) bone model printed on a desktop 3D-printer based on fused deposition modelling (FDM) technology with polylactic acid (PLA) and the effect of autoclave sterilization on the printed models. Methods Computed tomographic images of the tibia were obtained from 10 feline cadavers, used to create a bone surface-rendering file and sent to the 3D printing software. Right and left tibias were each printed five times with the FDM desktop 3D printer using PLA plastic material. Plastic models and cadaveric bones were measured with a profile projector device at six predetermined landmarks. Plastic bones were then sterilized using an autoclave before being re-measured applying the same method. Analyses of printed model size reliability were conducted using intra-class correlation coefficients (ICC) and Bland–Altman plots. Results The ICC always showed an almost perfect agreement when comparing 3D-printed models issued from the same cadaveric bone. The ICC showed moderate agreement for one measurement and strong/perfect agreement for others when comparing a cadaveric bone with the corresponding 3D model. Concerning the comparison of the same 3D-printed model, before and after sterilization, ICC showed either strong or perfect agreement. Clinical Significance Rapid-prototyping with our FDM desktop 3D-printer using PLA was an accurate, a reproducible and a sterilization-compliant way to obtain 3D plastic models.

“…Presurgical planning using 3D-printing anatomical models has been adopted in veterinary medicine [4][5][6] and related research [7,8], particularly in orthopaedic surgery, thus improving surgeon con dence and reducing surgical time, the occurrence of surgical complications, and surgeons' exposure to radiation [4,6,8]. These studies have indicated that 3D-printed models are bene cial when used for managing complex cases and when used by inexperienced surgeons [4,6,9]. Additionally, 3D-printed bone models are suitable for presurgical rehearsals of plate contouring, osteotomy, and the design of surgical guides [4,6,7,9].…”

Background: Three-dimensional (3D) printing techniques have been used to produce anatomical models and surgical guiding instruments in orthopaedic surgery. The geometric accuracy of the 3D printed replica may affect surgical planning. This study assessed the geometric accuracy of an acrylonitrile butadiene styrene (ABS) canine tibia model printed using fused deposition modelling (FDM) and evaluated its morphological change after hydrogen peroxide (H 2 O 2 ) gas plasma sterilisation. The tibias of six canine cadavers underwent computed tomography for 3D reconstruction. Tibia models were fabricated from ABS on a 3D printer through FDM. Reverse-engineering technology was used to compare morphological errors (root mean square; RMS) between the 3D-FDM models and virtual models segmented from original tibia images (3D-CT) and between the models sterilised with H 2 O 2 gas plasma (3D-GAS) and 3D-FDM models o n tibia surface and in cross-sections at: 5%, 15%, 25%, 50%, 75%, 85%, and 95% of the tibia length. Results: The RMS mean ± standard deviation and average positive and negative deviation values for all specimens in E FDM-CT (3D-FDM vs. 3D-CT) were significantly higher than those in E GAS-FDM (3D-GAS vs. 3D-FDM; P < 0.0001). Mean RMS values for E FDM-CT at 5% bone length (proximal tibia) were significantly higher than those at the other six cross-sections ( P < 0.0001). Mean RMS differences for E GAS-FDM at all seven cross-sections were nonsignificant. Conclusions: The tibia models fabricated on an FDM printer had high geometric accuracy with a low RMS value. The surface deviation in E FDM-CT indicated that larger errors occurred during manufacturing than during sterilisation. Therefore, the model may be used for surgical rehearsal and further clinically relevant applications in bone surgery.

“…Three-dimensional (3D) printing or additive manufacturing, previously known as rapid prototyping, is becoming increasingly popular in veterinary medicine as a method of reproducing bone replicas for management of orthopaedic cases. [10][11][12][13][14][15][16][17] In addition, 3D computer-assisted surgical planning (CASP) has many clinical applications in reconstructive surgery in human and veterinary medicine. 9,14,18 To the authors' knowledge, there is no current literature reporting the use of 3D CASP and printing in the repair of an articular fracture in veterinary medicine.…”

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.
