Several techniques have been described for canine pancarpal arthrodesis (PCA) with dorsal plating becoming the most accepted method for ease of placement despite the proposed biomechanical disadvantages. The aim of this study was to compare the biomechanical effects of the addition of crossed K-wires to a standard 2.7/3.5 mm hybrid PCA plate. A 2.7/3.5 mm hybrid PCA plate, alone and combined with crossed K-wires were tested. Six pairs of cadaver forelimbs were collected from medium-sized dogs with an average weight of 24 kg by elbow disarticulation.

OBJECTIVES: To evaluate the efficacy of juvenile pubic symphysiodesis (JPS) in a clinical setting for the early treatment of canine hip dysplasia (CHD), and to identify its indications and contraindications. METHODS: The final degree of CHD using the FCI (Fédération Cynologique Internationale) CHD classification in 5 Grades (A, B, C, D, E) was assessed at skeletal maturity in two homogeneous groups of dogs assessed at the age of 14 to 22 weeks and selected according to their susceptibility to CHD; one group was treated with JPS and one group was conservatively managed.

OBJECTIVE: To develop and assess clinical outcomes for osteochondral autografting for treatment of stifle osteochondrosis (OC) in dogs. STUDY DESIGN: Retrospective case series. ANIMALS: Dogs with stifle OC (n=10). METHODS: Osteochondral autografting was developed and optimized in canine cadavers and purpose-bred research dogs using the Osteochondral Autograft Transfer System (OATS). Dogs with stifle OC (n=10 dogs, 12 stifles) were then treated using the OATS system.

We investigated the prevalence of an anatomic variant of the proximal femur, termed the broomstick-like femoral head and neck formation, and its influence on the Féderation Cynologique Internationale (FCI) hip dysplasia score in 294 German Shepherd dogs. One-hundred and eighty (61%) of the 294 dogs in our study had this anatomic variant. The calculated area of the femoral heads in dogs with a broomstick-like conformation was 4.5 +/- 0.6 cm2 on the hip-extended view.

OBJECTIVE: To apply a novel technique and use the number and size (diameter and mean area) of vascular foramina to estimate potential blood supply in the metacarpophalangeal bones of dogs. ANIMALS: 28 Greyhounds. PROCEDURES: The forelimb sesamoid bones of 23 dogs were obtained after dogs were euthanized. Bones were isolated and examined by scanning electron microscopy. The number, diameter, and area of vascular foramina were determined by image analysis. Arterial distribution was assessed by use of resin injection in the sesamoid bones of 5 additional dogs.
