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.

RESULTS:

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.

Objective: To report the use of a 4.5 mm shaft screw for the management of humeral condylar fractures (HCF) and incomplete ossification of the humeral condyle (IOHC) in dogs, and to assess risk factors for complications. Methods: Dogs with HCF or IOHC that were managed with a 4.5 mm shaft screw with a minimum follow-up of six months from surgery were included. Data from the case records were used to identify risk factors for complications. Long-term follow-up was provided by an owner questionnaire and veterinary re-examination.

Objective: To compare the in vitro biomechanical performance of two String-of-Pearls (SOP) plate constructs in a canine distal humeral metaphyseal gap model. Methods: Seven pairs of canine cadaveric humeri, including the elbow joints, were prepared. One group consisted of a unilateral medially placed SOP plate with bicortical screws (UNI). The second group consisted of bilateral caudo-medial and caudo-lateral SOP plates applied with monocortical screws (BI). A 2 cm ostectomy was performed immediately proximal to the supratrochlear foramen.

Abstract

OBJECTIVE:

To describe a radiographic method for determination of the mechanical axes and joint orientation lines in orthogonal planes for the canine humerus and establish a range of normal joint orientation angles in a population of large breed dogs.

STUDY DESIGN:

Radiographic study.

SAMPLE POPULATION:

Humeri (n = 50) of skeletally mature, nonchondrodystrophic canine cadavers, weighing 20-40 kg with no evidence of orthopedic disease.

STUDY DESIGN:
Retrospective epidemiological study.
ANIMALS:
Labrador retrievers (n = 317; 592 elbow joints).

Arthroscopy is the gold standard for articular surface examination and is commonly advocated for diagnosing and treating cases of canine elbow dysplasia. Arthroscopy is generally regarded as a low-risk procedure, however there is a paucity of information in the small animal veterinary literature regarding the associated complication rates. In a retrospective study spanning a ten year period, 750 elective elbow arthroscopies were evaluated. Complications necessitating repeat surgery were defined as major, and were documented in 4.8% of dogs.
