OBJECTIVE: Identify radiographic risk factors for development of elbow dysplasia in giant breed dogs less than one year of age.

Category: Dysplasia - Elbow

OBJECTIVES: 1) To describe a radiographic method for determination of joint orientation lines and anatomical joint angles in orthogonal planes of feline radii; 2) to establish a range of normal radial joint orientation angles and anatomical axes in a feline population; and 3) to assess the repeatability and reliability of this methodology.

OBJECTIVE: To describe traumatic fracture of the medial coronoid process in dogs as a clinically distinct disease unrelated to congenital elbow dysplasia.

OBJECTIVE: To use micro-computed tomography (CT) to evaluate the fissure-fracture pattern in dogs affected by medial coronoid disease (MCD).

STUDY DESIGN: Prospective case-controlled study.

SAMPLE POPULATION: Client owned (n = 21) and cadaver dogs (n = 5).

Category: Elbow - Imaging

OBJECTIVE: To describe the technique of bi-oblique dynamic proximal ulnar osteotomy (BODPUO) and report the clinical outcome in a series of dog with medial compartment disease and other developmental elbow diseases.

STUDY DESIGN: Retrospective case series.

ANIMALS: Dogs (n=86; 120 elbows) treated for elbow disease with BODPUO.

Category: Elbow

OBJECTIVE: To describe the radiographic, computed tomography (CT), and arthroscopic findings in the elbow of dogs admitted for elbow lameness after previous arthroscopic treatment of medial coronoid disease (MCD).

STUDY DESIGN: Retrospective case series.

ANIMALS: Client-owned dogs (n = 25) admitted for elbow lameness after arthroscopic treatment.

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.
