Objective-To evaluate factors associated with lameness severity and hip joint range of motion in dogs with hip dysplasia and to assess the association between hip joint range of motion and degree of lameness. Design-Prospective case series. Animals-60 client-owned Labrador Retrievers with hip dysplasia. Procedures-Owners completed a questionnaire regarding their dogs' daily exercise duration and type (ie, low impact vs high impact) and lifestyle. Range of motion of affected hip joints was measured with a transparent plastic goniometer.
Associations among exercise duration, lameness severity, and hip joint range of motion in Labrador Retrievers with hip dysplasia.
Objective-To assess differences in sagittal plane joint kinematics and ground reaction forces between lean and obese adult dogs of similar sizes at 2 trotting velocities. Animals-16 adult dogs. Procedures-Dogs with body condition score (BCS) of 8 or 9 (obese dogs; n = 8) and dogs with BCS of 4 or 5 (lean dogs; 8) on a 9-point scale were evaluated. Sagittal plane joint kinematic and ground reaction force data were obtained from dogs trotting at 1.8 and 2.5 m/s with a 3-D motion capture system, a force platform, and 12 infrared markers placed on bony landmarks.

The underlying disease mechanisms for feline degenerative joint disease (DJD) are mostly unidentified. Today, most of what is published on mammalian arthritis is based on human clinical findings or on mammalian models of human arthritis. However, DJD is a common occurrence in the millions of domestic felines worldwide.

Veterinarians contacted to identify cats diagnosed with osteoarthritis (OA) provided information on signalment, method of diagnosis, treatment and concurrent disease. Owners of 50 cats were interviewed to collect information on specific OA signs observed in the home, relating to mobility, self-maintenance, social and exploratory behavior, and activity and habits at diagnosis and after treatment. Mean age at diagnosis was 12 y; concurrent diseases were common (44%).
Randomized, controlled clinical trial evaluating the efficacy of pulsed signal therapy in dogs with osteoarthritis.
Journal: Vet Surg
To evaluate the efficacy of pulsed signal therapy (PST) in reducing pain and increasing function in dogs with osteoarthritis (OA) using a randomized, blinded, controlled clinical trial.
Randomized, controlled, blinded clinical trial.
Adult dogs (n = 60) with moderate-to-severe clinical signs of OA.
Comparison of clinical and computed tomographic features between medial and lateral trochlear ridge talarosteochondrosis in dogs.
Journal: Vet Surg
To evaluate clinical and subchondral bone lesion differences between medial (MTRT-OC) and lateral trochlear ridge tarsocruralosteochondrosis (LTRT-OC).
Retrospective case series.
Dogs (n = 66) with MTRT-OC or LTRT-OC.
Clinical manifestations, response to treatment, and clinical outcome for Weimaraners with hypertrophic osteodystrophy: 53 cases (2009-2011).
Objective-To evaluate clinical manifestations, response to treatment, and outcome for Weimaraners with hypertrophic osteodystrophy (HOD). Design-Retrospective case series. Animals-53 dogs. Procedures-Medical records were reviewed for signalment, vaccination history, clinical signs, laboratory test results, response to treatment, and relapses. Radiographs were reviewed. Results-Clinical signs included pyrexia, lethargy, and ostealgia; signs involving the gastrointestinal, ocular, or cutaneous systems were detected. Of the 53 dogs, 28 (52.8%) had HOD-affected littermates.
Comparison of radiographic osteoarthritis scores in dogs less than 24 months or greater than 24 months following tibial plateau leveling osteotomy.
Journal: Can Vet J
Radiographic osteoarthritis scores were determined in 60 dogs up to 3 years following tibial plateau leveling osteotomy. Radiographs taken immediately following surgery and at long-term follow-up 1 to 3 years later were evaluated by 2 certified radiologists using a modified 32-point osteoarthritis scale. Changes in osteoarthritis scores were evaluated by paired t-tests and regression analysis. Sub-groups of dogs were formed to evaluate if osteoarthritis scores changed differently for follow-up periods of < 24 months compared with those > 24 months.
Skeletal morphology and morphometry of the lumbosacral junction in German shepherd dogs and an evaluation of the possible genetic basis for radiographic findings.
Journal: Vet J
The aim of this study was to identify skeletal variations in the lumbosacral junction (LSJ) of the German shepherd dog (GSD) compared with other large breeds. The radiographic traits of the LSJ were investigated in a group of 733 GSDs and a control group of 334 dogs of other breeds that were matched in terms of size. Nine morphological and 17 morphometric traits were recorded and analysed. Furthermore, the possibility of a genetic basis for these radiographic features was evaluated by calculation of genetic variance components.
Comparison of long-term outcomes associated with three surgical techniques for treatment of cranial cruciate ligament disease in dogs.
Journal: Vet Surg
