A 5-month-old castrated male Smooth Fox Terrier presented for a 1-month history of right thoracic limb lameness.

Physical examination revealed right elbow pain on extension and mild soft tissue swelling of the distal antebrachium. Radiographs and computed tomography showed elongated focal radiolucent regions in the distal radial metaphysis. There was incongruity of the right elbow with a short radius. Bone biopsy and histopathology of the regions confirmed a retained cartilaginous core characterised by bony trabeculae with frequently retained central cartilaginous cores.

Objective: To report complications and prognostic factors in dogs undergoing proximal abducting ulnar osteotomy (PAUL). To evaluate the ability to predict complications on the basis of post-operative radiographic examination.

Study design: Retrospective cohort study.

Animals: Sixty-six dogs.

Authors: Fiona J Coghill, Louisa K Ho-Eckart, Wendy I Baltzer

Objective: The aim of this study was to determine owner-assessed mid- to long-term outcome for dogs with medial compartment disease treated arthroscopically with fragment removal with or without proximal abducting ulnar osteotomy (PAUL).

Study design: This was a retrospective clinical study.

Authors: Alexandra B Kalamaras, Vincent Wavreille, Stephen C Jones, Alan S Litsky, Laura Selmic

Objective: To determine whether microwave ablation (MWA) modifies the biomechanical properties of the normal distal radius in the dog to better estimate the clinical impact of MWA as a tool for the treatment of neoplastic bone lesions.

Study design: Biomechanical experimental study.

Sample population: Sixteen pairs of dog forelimbs from 16 canine cadavers.

SAMPLE 23 cat cadavers.

OBJECTIVE: To compare the geometrical properties and bone mineral density (BMD) of the proximal radius between Saint Bernard and other giant breed dogs.

OBJECTIVE: To report the clinical outcomes of miniature- and toy-breed dogs with primary and previously treated distal radial and ulnar fractures (RUF) treated with a free-form multiplanar type II
