Assessment of the craniocaudal stability of four extracapsular stabilization techniques during two cyclic loading protocols: a cadaver study.

Objective: To (1) compare the effect of cyclic loading on craniocaudal tibial translation in cranial cruciate ligament (CrCL)-deficient stifles after extracapsular stabilization, and (2) evaluate the effect of peak force during cyclic loading on the rate of development of craniocaudal laxity.

Study Design: Biomechanical cadaveric study.

Sample Population: Cadaveric pelvic limbs (n = 24 pairs) from skeletally mature dogs.

Mechanical evaluation of adjunctive fixation for prevention of periprosthetic femur fracture with the Zurich cementless total hip prosthesis.

Objective: To evaluate whether cerclage wire or a lateral plate increases the peak-torque load to failure, compared to femora without adjunctive fixation, in femora implanted with Zurich Cementless stems.

Study Design: In vitro biomechanical study.

Sample Population: Paired femora from adult dogs (n = 24) weighing 28-35 kg.

Effect of lateral meniscectomy and osteochondral grafting of a lateral femoral condylar defect on contact mechanics: a cadaveric study in dogs.

Background: Osteochondral autograft transfer (OAT) aims at restoring normal articular cartilage surface geometry and articular contact mechanics. To date, no studies have evaluated the contact mechanics of the canine stifle following OAT. Additionally, there are no studies that evaluated the role of the meniscus in contact mechanics following OAT in human or canine femorotibial joints.

Mechanical properties of isolated loops of nylon leader material, polyethylene cord, and polyethylene tape and mechanical properties of those materials secured to cadaveric canine femurs via lateral femoral fabellae, toggles placed through bone tunnels, or bone anchors.

Objective: To determine mechanical properties of various prosthetic materials secured to cadaveric canine femurs via various methods and to compare results with those for isolated loops of prosthetic material.

Sample: 80 femurs obtained from cadavers of skeletally mature large-breed dogs.

Procedures: 10 femoral constructs in each of 8 groups (single circumfabellar loop of polyethylene cord, double loop of polyethylene tape secured via a bone anchor [BAPT], single or double circumfabellar loops of nylon leader material [CNL] or polyethylene tape [CPT], or single or double loops of polyethylene tape secured via a toggle placed through a bone tunnel [BTPT]) and 10 isolated loops of prosthetic material in each corresponding configuration were tested.

Occlusion of the thoracic duct using ultrasonically activated shears in six dogs.

Objective: To assess the feasibility of sealing the thoracic duct (TD) in dogs using ultrasonically activated shears via thoracoscopy.

Study Design: In vivo experimental study.

Animals: Mature dogs (n = 6).

Comparison of the guaranteed analysis with the measured nutrient composition of commercial pet foods.

Objective: To compare guaranteed and measured concentrations of nutrients in commercial pet foods.

Design: Cross-sectional study.

Sample Population: Annual inspection reports of pet food analyses from 5 states.
