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.

Introduction: Major goals in maxillofacial fracture treatment include to restore the dental occlusion, stabilise the major skeletal supports, restore the contour of the face and achieve proper function and appearance of the face. Titanium is considered an optimal material for maxillofacial reconstruction due to its biocompatibility, high strength, minimal inflammatory reaction and minimal imaging artefact.

Objective: To determine radiation exposure to surgical personnel and to evaluate the accuracy of a modified percutaneous lag screw fixation technique for sacroiliac luxation (SIL) under fluoroscopic guidance in dogs.

Study design: Cadaveric experimental study.

Sample population: Seventeen beagle cadavers with iatrogenic SIL.

Objective: The aim of this study was to compare the frequency of implant failure and the extent of pelvic canal narrowing associated with the fixation of ilial fractures in cats with a single veterinary cuttable plate (SLP) or double veterinary cuttable plates (DLP) applied to the lateral surface of the ilium.
