Fracture Fixation and Implants

Authors: Daniel J Wills, Jack Neville-Towle, Juan Podadera, Kenneth A Johnson

Objectives: The aim of this study was to report the use of computed tomography (CT) for postoperative evaluation of the accuracy of sacroiliac reduction and minimally invasive screw fixation in a series of five cats.

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).

Objective: To determine the biomechanical behavior of different plate systems used for oblique ilial fracture fixation in cats.

Study design: Ex vivo biomechanical study.

Sample population: Fifty fresh-frozen feline hemipelvises.

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.

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.

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).

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.

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.

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.

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.
