Osteochondrosis (OC) is common in large-breed dogs. According to the breeding guidelines of the Swiss kennel clubs, the shoulder joints are included in the radiographic screening for joint diseases in the Greater Swiss Mountain dog (GSMD) and the Border Collie (BC) since 1993 and 2003, respectively.
The aim of this study was to estimate the overall prevalence of humeral head OC in these 2 breeds in Switzerland based on the data of the Swiss National Dysplasia Committees. All radiographs were re-evaluated to assess single radiographic changes.

Radiography, magnetic resonance imaging (MRI), and ultrasonography are commonly used for diagnosis of shoulder osteochondrosis and osteochondritis dissecans (OC/OCD) in dogs, however there is a lack of published information on the relative diagnostic sensitivities of these modalities. The purpose of this prospective study was to compare diagnostic sensitivities of these modalities for detecting shoulder OC/OCD in a group of dogs, using arthroscopy as the reference standard.

Shoulder joint hemiarthroplasty for treatment of a severe osteochondritis dissecans lesion in a dog.
Journal: Vet Comp Orthop Traumatol
Introduction: Partial resurfacing of the humeral head has been reported in humans to treat humeral osteochondritis dissecans. The aim is to describe a custom-made humeral resurfacing prosthesis for treatment of severe humeral head osteochondritis disse-cans in a dog. Case report: A seven-month-old female entire St. Bernard dog was presented with a 10 week history of severe left thoracic limb lameness. Radiography, arthroscopy and magnetic resonance imaging confirmed an extensive osteochondritis dissecans lesion affecting the caudal, medial and central regions of the humeral head.

Osteochondrosis is a common developmental abnormality affecting the subchondral bone of immature, large breed dogs. The purpose of this retrospective study was to describe CT lesions detected in scapulohumeral joints of 32 immature dogs undergoing CT for thoracic limb lameness. Eight dogs (14 scapulohumeral joints) had arthroscopy following imaging. Thirteen dogs (19 scapulohumeral joints) were found to have CT lesions, including 10 dogs (16 scapulohumeral joints) with subchondral bone lesions and 3 dogs with enthesopathy of the supraspinatus tendon.

Objective

Study Design
Retrospective case series
Animals
Dogs (n = 42) with scapular tumors.

Soft tissue injuries of the shoulder are an important cause of forelimb lameness in dogs. The objectives of this canine cadaver study were to describe normal anatomy of shoulder soft tissue structures using computed tomography (CT) and computed tomographic arthrography (CTA) and to determine the effects of positioning on visualization of shoulder soft tissue structures. Thirteen forelimbs were removed from eight canine cadavers. Two forelimbs were used for contrast dose optimization.
