OBJECTIVE: To describe the clinical signs and histologic changes in cats clinically affected with medial humeral epicondylitis (MHE) and evaluate long-term outcome after either conservative or surgical treatment.

STUDY DESIGN: Prospective cohort study.

ANIMALS: Client-owned cats (n = 17) with MHE.

Category: Elbow

OBJECTIVE: To investigate the ability of medical infrared imaging to differentiate between normal canine elbows and those with abnormal elbows (elbow dysplasia).

STUDY DESIGN: Prospective cohort study.

ANIMALS: Dogs with normal (n = 15) and abnormal (n = 14) elbows.

METHODS: Infrared imaging was performed on all dogs and data analyzed via descriptive statistics and image pattern analysis software. Animals with elbow dysplasia had arthroscopic procedures to confirm the presence of elbow disease.

Congenital radial head sub-luxation was diagnosed in a 7-month-old, neutered male shih tzu that presented with a limb deformity and severe lameness of the right fore limb. Radiography revealed a craniolateral sub-luxation of the right radial head, which was treated by radial head ostectomy, fixation of the radius to the ulna with a screw and joint stabilisation with suture-anchors and cerclage wire.

Surgical treatment followed by physiotherapy resulted in a fully functional, well-aligned and non-painful elbow.

Erosion of the medial compartment of the elbow joint refers to full thickness cartilage loss with exposure of the subchondral bone (modified Outerbridge grades 4-5) of the medial part of the humeral condyle (MHC) and the corresponding ulnar contact area. This finding may appear in the absence of an osteochondral fragment or a cartilage flap, or in combination with fragmentation of the medial coronoid process (MCP) or osteochondritis dissecans (OCD) of the MHC.

OBJECTIVES: To compare the development, monitored by radiography and computed tomography, of the antebrachia and elbow joints in seven Labrador Retrievers with healthy elbow joints and in seven Labrador Retrievers that developed medial coronoid disease (MCD), in order to determine whether disturbances in the development of the antebrachia and elbow joints, between the age of six and 17 weeks may lead to medial coronoid disease.

OBJECTIVE: To describe the magnetic resonance imaging (MRI), arthroscopic, and histopathologic changes in dogs with medial coronoid disease and to identify potential relationships between these findings.

STUDY DESIGN: Retrospective case series.

Category: Dysplasia - Elbow - Imaging

OBJECTIVE: To document the progression of disease after an unloading procedure when combined with arthroscopic debridement to treat osteochondrosis (OC) lesions affecting the medial humeral condyle in juvenile dogs without medial compartment disease.

STUDY DESIGN: Retrospective case series.

ANIMALS: Dogs with medial humeral condyle OC (n = 6)

OBJECTIVES:  To report short- and long-term outcomes after arthroscopic treatment in young large breed dogs affected by medial coronoid process disease (MCPD) and identify variables affecting outcome.

STUDY DESIGN: Prospective observational case series.

ANIMALS: Large breed dogs <3 years old (n = 15; 23 elbows).

To determine if the use of a six degrees of freedom marker set would allow new kinematic data of the canine thoracic limbs to be calculated. To identify any significant differences in thoracic limb gait patterns in all planes of motion, between the normal canine population and patients with confirmed medial coronoid disease (MCD).

Elbow dysplasia is a heritable disease that is a common cause of lameness and progressive elbow osteoarthritis in young large breed dogs. The Orthopedic Foundation for Animals (OFA) screens elbow radiographs, and assigns grades 0-3 based on presence and severity of bony proliferation on the anconeal process. Grade 1 is assigned when less than 3 mm is present and considered positive for dysplasia.
