Effects of Angled Dynamic Compression Holes in a Tibial Plateau Levelling Osteotomy Plate on Cranially Directed Fragment Displacement Vet. Comp. Orthop. Traumatol. (IF 1.3) Pub Date : 2023-02-16 Richard C.Y. Looi, Joanna D. White, Daniel R. James
Objective To compare angled dynamic compression holes in a tibial plateau levelling osteotomy (TPLO) plate to a commercially available TPLO plate in an ovine cadaveric model. Study Design Ovine tibias (40 bones) were mounted on a custom-made securement device and radiopaque markers were placed to aid radiographic measurements. A standard TPLO procedure was performed on each tibia with either a custom-made

Three-Dimensional Morphometry of the Canine Pelvis: Implications for Total Hip Replacement Surgery Vet. Comp. Orthop. Traumatol. (IF 1.3) Pub Date : 2023-02-16 Agnieszka B. Fracka, Claudia Zindl, Matthew J. Allen
Objectives Two-dimensional measurements of acetabular geometry are widely used for the assessment of acetabular component orientation following total hip replacement (THR). With the increasing availability of computed tomography scans, there is an opportunity to develop three-dimensional (3D) planning to improve surgical accuracy. The aim of this study was to validate a 3D workflow for measuring angles

Accuracy of Caudocranial Canine Femoral Radiographs Compared to Computed Tomography Multiplanar Reconstructions for Measurement of Anatomic Lateral Distal Femoral Angle Vet. Comp. Orthop. Traumatol. (IF 1.3) Pub Date : 2023-02-16 Elliott Anthony Clark, Anna Maria Condon, Daniel Michael Ogden, Steven Riddiford Bright
Objective This study aimed to compare the accuracy of sternal recumbency caudocranially obtained radiographs of canine femora to computed tomographic (CT) frontal plane reconstructions of the same femora for assessing anatomic distal lateral femoral angles (aLDFA). Study Design Multicentre, retrospective study utilizing 81 matched radiographic and CT studies of clinical patients undergoing assessment

Prevalence of Work-Related Musculoskeletal Symptoms in Veterinary Surgeons – A Cross-Sectional Survey Vet. Comp. Orthop. Traumatol. (IF 1.3) Pub Date : 2023-02-16 Sun Young Kim, Denny Yu, Micha C. Simons, Gert J. Breur
Objectives The aim of this study was to determine the prevalence of work-related musculoskeletal symptoms (MSS) in veterinary surgeons using an online survey. Methods An online survey was distributed to 1,031 diplomates of American College of Veterinary Surgeons. Responses were collected with data regarding surgical activities, experience with various types of MSS in 10 different body sites and attempts

Minimally Invasive Arthrodesis of the Equine Proximal Interphalangeal Joint: A Biomechanical Comparison of Three 5.5-mm Cortical Screws Inserted in Lag Fashion and Two 7.0-mm Headless Cannulated Dual-Pitch Compression Screws Vet. Comp. Orthop. Traumatol. (IF 1.3) Pub Date : 2023-02-09 Aires Santana Rumpel, Anderson Luiz De Carvalho, Jakson Manfredini Vassoler, Matheus Lothar Schmidt, Cleiton Costa Mertz, Cesar Augusto Camacho Rozo, Joanna Kulczynski Campos, Marcelo Meller Alievi
Objective The aim of this study was to compare the biomechanical properties of two minimally invasive arthrodesis techniques of the equine proximal interphalangeal (PIP) joint (three transarticular 5.5-mm cortical screws [AO-3TLS] vs. two transarticular 7.0-mm headless cannulated multi-use compression screws [MUC-2TS]) in dynamic non-destructive testing and compression testing to failure. Study Design The

Use of Ultrasonography in Diagnosis of Medial Compartment Disease of the Elbow in Dogs Vet. Comp. Orthop. Traumatol. (IF 1.3) Pub Date : 2023-02-01 Maxime Jacqmin, Véronique Livet, Juliette Sonet, Mathieu Harel, Eric Viguier, Pierre Henri Moissonnier, Thibaut Cachon
Objective The objective of this prospective study was to evaluate the use of ultrasonography in the diagnosis of medial coronoid process disease in unclear cases. Study Design Fifteen elbows (on thirteen dogs) for which radiography and computed tomography did not lead to a clear diagnosis of medial coronoid process disease were included. On each elbow, ultrasonography was performed with a high frequency
