OBJECTIVE:
To (1) evaluate the normal extraosseous blood supply of the cranial aspect of the canine radius and (2) to compare the effects of minimally invasive (MIPO) and open plating technique on its preservation.
STUDY DESIGN:
Experimental cadaveric study.
SAMPLE POPULATION:
Adult canine thoracic limbs (n = 36) obtained from cadavers weighing 25-35 kg.
METHODS:

OBJECTIVE:
To evaluate clinical and subchondral bone lesion differences between medial (MTRT-OC) and lateral trochlear ridge tarsocruralosteochondrosis (LTRT-OC).
STUDY DESIGN:
Retrospective case series.
ANIMALS:

Objective-To determine complications and outcomes for dogs that underwent digit amputation. Design-Retrospective case series and owner survey. Animals-33 client-owned dogs. Procedures-Medical records of dogs that underwent digit amputation were evaluated. Signalment, digits amputated, level of amputation, reason for amputation, and complications were recorded. Owners were contacted via mail or telephone to collect follow-up information. Results-35 digit amputation procedures were performed for the 33 dogs in the study (1 dog underwent 3 procedures).

Objective: To assess the ability of a contrast-enhanced magnetic resonance imaging (MRI) technique to quantitatively determine glycosaminoglycan content in canine articular cartilage. Methods: Fifty-four full-thickness cartilage discs were collected from the femorotibial and scapulohumeral joints of three adult dogs immediately following euthanasia. One set of discs from each dog was analysed for glycosaminoglycan content using a colourimetric laboratory assay.

Objective-To evaluate the load redistribution mechanisms in walking and trotting dogs with induced forelimb lameness. Animals-7 healthy adult Beagles. Procedures-Dogs walked and trotted on an instrumented treadmill to determine control values for peak and mean vertical force as well as verticle impulse for all 4 limbs. A small sphere was attached to the ventral pad of the right forelimb paw to induce a reversible lameness, and recordings were repeated for both gaits. Additionally, footfall patterns were assessed to test for changes in temporal gait variables.

Objectives: To evaluate bone healing in an experimental radial ostectomy in dogs treated with autologous platelet-rich plasma (PRP), through histological, densitometric, radiographic studies, as well as expression of growth factors in the ostectomy gap. Methods: Twenty-one dogs were randomly divided into either a control or a PRP group. All underwent unilateral ostectomy of the radius to generate a gap of 2.0 mm, that was stabilized with external skeletal fixation. The ostectomy gap was either filled with PRP or left empty as a control.

Objectives: Since external coaptation is applied clinically to prevent plate failure during healing in canine pancarpal arthrodesis (PCA), we tested the hypothesis that external coaptation does not significantly reduce plate strain in an experimental ex vivo model of canine PCA. Methods: Ten thoracic limbs from healthy Greyhounds euthanatized for reasons un- related to the study were harvested and the carpus was stabilised with a dorsally applied 2.7/3.5 mm hybrid PCA plate.

Objective-To evaluate fracture healing after minimally invasive plate osteosynthesis (MIPO) or open reduction and internal fixation (ORIF) of coexisting radius and ulna fractures in dogs via ultrasonography and radiography. Design-Prospective cohort study. Animals-16 dogs with radius-ulna fractures that underwent MIPO (n = 9; 2 dogs were subsequently not included in the analyses because of incomplete follow-up information) or ORIF (7). Procedures-Dogs in the 2 treatment groups were matched by age, body weight, and configuration of the fractures.
