Biomechanical Comparison of Double 2.3-mm Headless Cannulated Self-Compression Screws and Single 3.5-mm Cortical Screw in Lag Fashion in a Canine Sacroiliac Luxation Model: A Small Dog Cadaveric Study

Authors: AhRan Kang, Haebeom Lee, Arim Lee, Yoonho Roh, Bokyun Sim, Jaemin Jeong

Objective: The aim of this study was to evaluate the feasibility of safe positioning of double 2.3-mm headless cannulated self-compression screws (HCS) in a small dog cadaveric sacroiliac luxation model and to compare the static rotational biomechanical properties of fixation repaired using two different screw systems with a minimally invasive osteosynthesis technique: double 2.3-mm HCS and a single 3.5-mm standard cortical screw placed in a lag fashion.

Authors: Charlie Brincin et al.

Objective: To determine the influence of radiographic examination on the recommendations made at the time of planned re-evaluation of dogs after medial patellar luxation (MPL) surgery.

Study design: Retrospective multi-institutional case series.

Animals: Client-owned dogs (N = 825) that underwent MPL surgery.

A novel surgical treatment of type 3 congenital elbow luxation in a dog

Authors: C L Gordon, C Thomson, Nsl Webster

Congenital luxation of the ulnar and radius is a rare orthopaedic condition in the dog.

This case report describes a novel surgical treatment for congenital elbow luxation in a medium-breed dog. A 6-week-old Kelpie presented for left forelimb lameness and deformity. Radiographs and computed tomography (CT) confirmed the diagnosis of unilateral ulnar and radius luxation. The surgical repair involved open reduction followed by fixation with an extraarticular pin and a transarticular external fixator.
