Effects of exposure to ambient air (20 to 22 C) on articular cartilage from rabbits were evaluated. Bilateral arthrotomies were performed on the stifles of 18 New Zealand White rabbits. The cranial surface of the left distal femur, including the articular cartilage of the trochlea, was exposed to air for 2 hours. The right stifle was opened and closed(More)
The biomechanics of motion and rehabilitation are complex, with many tissue types and structures involved. In addition, consideration must be given to the stage of tissue healing with some injuries, such as fractures.A more thorough knowledge of some of the infrequently discussed biomechanical aspects of musculoskeletal tissues and motion during(More)
Cache-coherent nonuniform memory access (CC-NUMA) machines have been shown to be a promising paradigm for exploiting distributed execution. CC-NUMA systems can provide performance typically associated with parallel machines, without the high cost associated with parallel programming. This is because a single image of memory is provided on a CC-NUMA machine.(More)
OBJECTIVE To evaluate postoperative morbidity in dogs after experimental cranial cruciate ligament transection and immediate stifle stabilization using an arthroscopically assisted or open arthrotomy technique. STUDY DESIGN Experimental, prospective study. ANIMALS Thirteen mature, healthy dogs. METHODS Dogs were randomly assigned to 1 of 2 groups.(More)
The clinical, laboratory, radiographic, and histologic features and the response to therapy in three dogs with actinomycosis are reported. One dog (dog 1) had a 12-cm nonresectable mass extending from the ventrolateral chest wall into the left ventricular myocardium. Another dog (dog 2) had a diffuse peritonitis with "sulfur granules" and two large masses.(More)

This article discusses principles of corrective osteotomy and describes operative plans for specific growth deformities such as premature closure of the distal ulna, asynchronous growth of the radius and ulna in achondroplastic breeds, retarded growth of the distal radius, retarded growth of the proximal radius, and synostosis of the radius and ulna.
OBJECTIVE To compare the 3-D motion of the pelvic limb among clinically normal dogs and dogs with cranial cruciate ligament (CCL)-deficient stifle joints following tibial plateau leveling osteotomy (TPLO) or lateral fabellar-tibial suture (LFS) stabilization by use of an inverse dynamics method. ANIMALS 6 clinically normal dogs and 19 dogs with(More)
OBJECTIVE To use an inverse dynamics method to describe the motion of the canine pelvic limb in 3 dimensions. ANIMALS 6 healthy adult dogs. PROCEDURES For each dog, 16 anatomic and tracking markers were used to define the center of rotation for the pelvic limb joints and a kinematic model was created to describe the motion of the pelvic limb. Kinetic,(More)
OBJECTIVE To determine the effect of recombinant canine somatotropin (STH) on radiographic, densitometric, and biomechanical aspects of bone healing using an unstable ostectomy gap model. STUDY DESIGN After an ostectomy of the midshaft radius, bone healing was evaluated over an 8-week period in control dogs (n = 4) and dogs receiving recombinant canine(More)
OBJECTIVE To report a novel method of treating femoro-patellar instability in association with severe femoro-patellar osteoarthritis, by substituting the femoral trochlear with a patellar groove replacement prosthesis. STUDY DESIGN Retrospective case series. METHODS Preoperative lameness was scored from 0-4, and radiographic studies including standard(More)
