Radius/Ulna

Retained cartilaginous core in the distal radius of a small breed dog

Authors: J T Nelson, C F Monahan, D G Sledge, S Kim

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.

Authors: Alan Danielski, Alexander Krekis, Russell Yeadon, Miguel Angel Solano, Tim Parkin, Aldo Vezzoni, Ingo Pfeil

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.

Mid- to Long-Term Outcome after Arthroscopy and Proximal Abducting Ulnar Osteotomy Versus Arthroscopy Alone in Dogs with Medial Compartment Disease: Thirty Cases

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.

Impact of microwave ablation treatment on the biomechanical properties of the distal radius in the dog: A cadaveric 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.
