Objective: To compare the in vitro stability of acetabular cups with peripherally reinforced fixation in a model of uncemented total hip replacement in dogs.

Sample: 63 polyurethane foam blocks and 3 acetabular implant designs: hemiellipsoidal (Model A) and 2 models with equatorial peripheral fins (Model B with 1 level and Model C with 2 levels of fins).

Objective: The aim of this study is to describe the use of String of Pearls (SOP) plates for the surgical management of feline pelvic fractures, including surgical technique, proposed indications, complications, and outcomes in a cohort of cats.

Study design: This study is a single-center retrospective clinical case series.

Authors: Alexandre Thibault, Philippe H Haudiquet

Objective: To report the outcome of double pelvic osteotomy (DPO) for craniodorsal luxation of total hip replacement (THR).

Study design: Retrospective case series.

Animals: Eleven client-owned animals.

Objective: Canine hip dysplasia is a common orthopaedic disease in dogs. The Norberg angle value is a measure of hip joint laxity. The aim of this study was to quantify the degree of rotation necessary to consider the radiograph as inadequately positioned and to determine the influence of rotation on the Norberg angle.

The aim of this retrospective study was to verify whether the radiographic morphologic differences detected within the first three grades of hip dysplasia (A, B, C) of each of the five selected breeds and within the same breeds were statistically significant enough to require a breed-specific evaluation.

Objectives: The main aim of this study was to report the surgical technique, the complications and the clinical outcomes of the mini-Tight Rope system (mini-TR) for a modified hip toggle stabilization of coxofemoral luxation in cats.

Study design: A multicentre retrospective study.

Animals: Thirty-two client-owned cats.

Authors: Adheip Prabakaran, Paul L Jenkins

Objective: The aim of this study was to assess the kinetic and radiographic outcome of unilateral double pelvic osteotomy (DPO) using a temporospatial pressure walkway, preoperative and postoperative radiographs.

Objective: Compare biomechanical properties of femurs implanted with either BioMedtrix biological fixation with interlocking lateral bolt (BFX®+lb) or cemented (CFX®) stems when subjected to 4-point bending or axial torsional forces.

Objective: To develop quantitative measures that, when combined with the Fédération Cynologique Internationale (FCI) score, would potentially enhance the accuracy of the scoring process.

Animals: 153 client-owned purebred German Shepherd Dogs with normal and near normal (71 dogs) and dysplastic coxofemoral joint (82 dogs).
