Objective: To evaluate the accuracy of six depth gauges used in three tibial plateau leveling osteotomy (TPLO) plate holes.

Study design: Ex vivo experimental study.

Animals and sample population: Cadaveric canine limbs (n = 10), one 25-mm-thick wood board, and one 33.8-mm-diameter polyvinyl chloride (PVC) pipe.

Authors: Norihiro Muroi et al.

Objective: This study aimed to evaluate implant-induced osteoporosis (IIO) development in toy breed dogs treated using internal fixation with digital radiographs as the index of pixel values.

Authors: Antonio Pozzi, Daniel D Lewis, Logan M Scheuermann, Emanuele Castelli, Federico Longo

Objective: To summarize and discuss peer-reviewed studies on minimally invasive osteosynthesis (MIO) of long bone, physeal, and articular fractures in dogs and cats.

Study design: Invited review.

Methods: A critique of literature was performed to assess MIO feasibility, outcomes, and complications through PubMed, Scopus, and CAB abstracts research databases (2000-2020).

Authors: M. Higuchi, M. Katayama

Objectives To describe the results of orthogonal plating (OP) as a treatment for fractures of the radius and ulna in toy-breed dogs.

Numerous animal and human studies have demonstrated the benefit of controlled interfragmentary motion on fracture healing. In this study, we quantified interfragmentary motion and load transfer in tibial fractures fixed using a novel intramedullary nail (IMN) that allows controlled axial motion.

Objective: To determine the accuracy of transcondylar screws placed from medial-to-lateral using preoperative planning on computed tomography (CT) and an aiming device in elbows with humeral intracondylar fissures (HIFs).

Study design: Retrospective case series.

Animals: Twenty-five client-owned dogs with HIF.

Authors: S Devereux, M Jack, A Worth, J Bridges

Aims: To compare the force to failure under axial loading of a calcaneotibial screw placed approximately perpendicular to the tibia with that of a screw placed perpendicular to the calcaneus, when used to immobilise the tarsus in an ex vivo canine model.

Objective: The aim of this study was to categorize the presentation, management, complications and long-term outcome of canine acetabular fractures, and to determine the factors affecting outcome.

Materials and methods: Case records and imaging for dogs with acetabular fractures were reviewed with long-term follow-up via canine brief pain inventory (CBPI) and owner questionnaires.

Objective: To determine the influence of interlocking screw threads on the biomechanical properties of repaired canine humeral condylar fractures.

Study design: Ex vivo biomechanical study.

Sample population: Thirty-six humeral condyles.
