Elbow

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).

Category: Arthroscopy - Elbow
Authors: Caron A, Caley A, Farrell M, Fitzpatrick N1.
Journal: VCOT

OBJECTIVES:

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.

Disruption of the triceps tendon insertion is an uncommon injury, with only a few reports of traumatic triceps tendon avulsion in dogs or cats present in the veterinary literature. Although this injury has been previously described in two dogs that had received a local injection of corticosteroids for the treatment of soft tissue injuries, reports with long term clinical follow-up and outcome in working dogs are lacking. This report describes two surgically treated cases of complete triceps tendon avulsion rupture in Malinois police dogs.

OBJECTIVE:

To report thoracic limb alignment values in healthy dogs; to determine if limb alignment values are significantly different when obtained from standing versus recumbent radiographic projections.

STUDY DESIGN:

Prospective cross-sectional study.

ANIMALS:

Labrador Retrievers (n = 45) >15 months of age.

METHODS:

OBJECTIVE:

To (1) evaluate thoracic limb loads and symmetry, and elbow function and morphology, before and after arthroscopic treatment of unilateral medial coronoid process disease (MCPD), and (2) determine if functional variables correlate with morphologic findings.

STUDY DESIGN:

Prospective case series.

ANIMALS:

Dogs (n = 14) with thoracic limb lameness.

METHODS:

Authors: Wendelburg KM1, Beale BS.
Journal: Vet Surg

OBJECTIVE:

To evaluate medium and long term effects of sliding humeral osteotomy (SHO) in dogs.

STUDY DESIGN:

Prospective study.

ANIMALS:

Dogs (n = 32).

METHODS:

Data (2008-2010) collected from medical records included force plate data, radiographs, and a 15 question owner survey of dog soundness before SHO and at final evaluation.

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).

Coronoid dysplasia (CD) or medial coronoid disease is part of canine elbow dysplasia and eventually results in osteoarthrosis. Although CD was originally attributed to disturbed endochondral ossification, more recent data point to the subchondral bone. The objective of this study was to assess dysplastic bone and cartilage of dogs that underwent unilateral or bilateral arthroscopic subtotal coronoidectomy for the treatment of CD. Arthroscopic findings and histopathology of bone and cartilage removed from elbow joints with CD were compared.
