Computer-assisted surgical correction of an antebrachial deformity in a dog

Abstract

Computer assistance was valuable for locating and quantifying this antebrachial deformity and conceptualising the corrective surgery. The results of our study suggest that rapid prototyping can be used to create models and saw guides to simplify one-stage corrective osteotomies and more accurately treat angular limb deformity.

Computation of Femoral Canine Morphometric Parameters in Three‐Dimensional Geometrical Models

“…The increased emphasis on 3D computation is not only relevant for diagnostic purposes, but also for surgical planning . The 3D computations are more reliable for planning corrective osteotomies, including identifying the precise localization of the center of rotation of angulation (CORA) and the accurate orientation of the osteotomy cutting plane . The 3D models are regarded as essential for customizing templates and surgical devices for correction of bone deformities .…”

Three‐dimensional printing of orbital and peri‐orbital masses in three dogs and its potential applications in veterinary ophthalmology

“…Although not as hard as bone, it can be used to identify and practice osteotomy and ostectomy sites as well as contour metallic orthopedic implants prior to surgery. 3,4,7 Pertinent to the cases discussed in this report, there are multiple described techniques for the orbitotomy procedure in dogs, [29][30][31][32][33] and some of these, such as the modified lateral 29 and transfrontal 32 approach, require performing an osteotomy at multiple sites. Therefore, identifying and practicing the optimal surgical approach can decrease patient morbidity, surgical time, and surgical errors.…”

“…The 3D-printed object is created using a variety of materials that are added one layer at a time rather than sculpting a structure from solid material. 7,10,11 Despite its recent introduction in veterinary medicine, 3D printing has already been utilized for biomedical education 7 in addition to clinical orthopedic [3][4][5] and neurologic 7 surgery cases. The printing of 3D models is becoming increasingly more available and cost-effective, and the diagnostic tests (MRI and CT) needed for the first step in fabrication of these models are common in many veterinary specialty practices.…”

“…The newest imaging tool that has been introduced into the veterinary profession is three-dimensional (3D) printing, and this has the potential to bring a new dimension to diagnostics and surgery across all disciplines. [3][4][5][6][7] The idea of 3D printing first appeared in 1986 through a US patent filed by Charles W. Hull, 8 and since then, multiple techniques have been developed. 7,[9][10][11] A 3D print can be obtained by first acquiring a CT scan or MRI, then utilizing computer software to create a digital template for the print.…”

Cross‐sectional imaging: the key to anatomy

“…The ability of cross-sectional modalities to reconstruct 3D anatomy, especially bony structures, saves dissection or sectioning of anatomical specimens and allows a multitude of different approaches (Zarucco and others 2006) and also helps with orthopaedic surgical planning (Vandeweerd and others 2009). Bony malformations and deformities may be visualised without disturbing the overlying soft tissue structures (Crosse and Worth 2010). …”
