Mechanical assessment of two hybrid plate designs for pancarpal canine arthrodesis under cyclic loading.

Pancarpal canine arthrodesis (PCA) sets immobilization of all three carpal joints dorsal plating to result in bony fusion. Whereas the first version of the plate uses a round hole (RH) for the radiocarpal (RC) screw region, its modification into an oval hole (OH) in a later version improves versatility in surgical application. The aim of this study was to mechanically investigate the fatigue life of the PCA plate types implementing these two features-PCA-RH and PCA-OH.

Mechanical Evaluation of Two Hybrid Locking Plate Designs for Canine Pancarpal Arthrodesis.

Hybrid locking pancarpal arthrodesis plates were designed with either a round (RH) or an oval (OH) radiocarpal hole, the latter allowing varied screw positioning. Due to concerns about potential decreased structural properties of the OH design, our aim was to compare the mechanical behavior of the contrasting plates using combined finite element analysis (FEA) and mechanical testing. Pancarpal arthrodesis plates with RH or OH design were assigned to three fixation techniques ( = 6), prebent at 20°, and fixed to canine forelimb models with simulated radius and radiocarpal and 3rd metacarpal bones.

Comparison of hydroalcoholic rubbing and conventional chlorhexidine scrubbing for aseptic skin preparation in dogs.

Objective: To compare preparation time, ease of application, and elimination of skin contamination of 3 skin preparation methods for asepsis.

Study Design: Experimental study.

Animals: Healthy dogs (n = 6) with no clinical signs of skin disease.

Segmentation of the canine population in different femoral morphological groups.

Objective: The incidence of femoral traumatology and hip dysplasia shows the need to design canine specific femoral implants in veterinary surgery. A good knowledge of femoral morphology, and particularly of intra-species variability, is required to develop a well-adapted canine femoral intramedullary implant. The aim of this study is to evaluate the morphological variability of the canine femur and to propose a segmentation of this population.

Geometric analysis of the proximal femur in a diverse sample of dogs.

Dogs are often used as experimental models for studies of human hip replacement. A precise knowledge of femoral morphology is required to improve osteointegration of cementless prostheses by bone ingrowth or determination of the best design for total hip prostheses. To better understand the differences between breeds, we measured or calculated 24 external and internal features of the femur on standard radiographs of dogs that differed greatly in size and body type.
