Tibial Tuberosity Transposition Fixation with a Locking Plate during Medial Patellar Luxation Surgery: An Ex Vivo Mechanical Study
Authors: Esa V Eskelinen, Ari P Suhonen, Juha V Virolainen, William D Liska

Objectives: The purpose of this study was to compare the load at failure, stiffness and mode of failure between three types of tibial tuberosity transposition fixation techniques: (a) pin and figure-8 tension band wire (Pin-TBW), (b) locking plate with pin and a tension band wire (Plate-Pin-TBW) and (c) locking plate with a pin (Plate-Pin).

Biomechanical comparison of screw and suture fixation for temporary transarticular tarsocrural immobilization in canine cadavers
Authors: Laura M Goffart, Ullrich Reif, Bianca F Hettlich, Martin Kramer

Objective: To biomechanically evaluate an ultrahigh-molecular-weight polyethylene (UWMWPE) suture for temporary tarsocrural immobilization as a potential alternative to the existing surgical method, which uses a 4.5 AO/ASIF calcaneotibial cortical screw.

Study design: Randomized in vitro biomechanical study.

Biomechanical evaluation of two dorsal and two ventral stabilization techniques for atlantoaxial joint instability in toy-breed dogs
Authors: Alexia Progin, Benjamin Voumard, Brian Friker, Franck Forterre

Objective: To compare the biomechanical properties of atlantoaxial joints (AAJs) in canine vertebral column specimens stabilized with 4 techniques (dorsal wire, modified dorsal clamp, ventral transarticular pin, and augmented ventral transarticular pin fixation) after transection of the AAJ ligaments.

Sample: 13 skull and cranial vertebral column segments from 13 cadaveric toy-breed dogs.

Repair of Fractures of the Lateral Aspect of the Humeral Condyle in Skeletally Mature Dogs with Locking and Non-Locking Plates
Authors: Matthew K Eayrs, Vincent Guerin, James Grierson, Andrew P Moores

Objective: The aim of this study was to report the functional outcome and complications following transcondylar screw and epicondylar plate fixation of skeletally mature dogs with fractures of the lateral aspect of the humeral condyle using a string of pearls, limited contact dynamic compression plate (LC-DCP) or locking compression plate (LCP).

Combined internal fixation and transarticular external skeletal fixation to treat traumatic patellar fractures in five dogs
Authors: M Sprocatti, E Kvale, M Solano

Case history: Medical records of dogs (n = 5) that had been treated for patellar fracture with transarticular external skeletal fixation (TA-ESF) to augment internal fixation, at a single referral hospital in the United Kingdom between 2015 and 2017, were reviewed.

Biomechanical comparison of humeral condyles with experimental intracondylar fissures immobilized with a transcondylar positional or a lag screw: An ex-vivo study in dogs
Authors: Tomas Serrano Crehuet, Pablo de Linares Tuduri, Jeffery Biskup

Objective: To compare the axial biomechanical properties of intracondylar humeral osteotomies fixed with 4.5 mm transcondylar positional or cortical lag screws.

Study design: Ex vivo study.

Sample population: Paired humeri from 21 canine cadavers.

Influence of Screw-Hole Defect Size on the Biomechanical Properties of Feline Femora in an Ex Vivo Model
Authors: QiCai Jason Hoon, Tian Wang, Evelyn Hall, William R Walsh, Kenneth A Johnson

Objective: The study aims to evaluate the biomechanical properties of feline femora with craniocaudal screw-hole defects of increasing diameter, subjected to three-point bending and torsion to failure at two different loading rates.

Infection rate treating radial and ulnar fractures using bone plate fixation without antibiotic prophylaxis
Authors: H Schmökel, D Skytte, M Barsch

Objectives: To evaluate the effectiveness and complication rate of a 1.5- and 2.0-mm titanium locking plate for the treatment of radial and ulnar fractures in small dog breeds and cats without peri-operative antibiotic prophylaxis in a prospective case series.
