OBJECTIVE: To assess relationships of acetabular volume (AV), femoral head volume (FV), and portion of the femoral head within in the acetabulum (FVIA) with each other and with degrees of hip joint laxity and degenerative joint disease from youth to maturity in dogs predisposed to developing hip joint osteoarthritis (OA).
ANIMALS: 46 mixed-breed half- or full-sibling hound-type dogs.

The aim of this study was to evaluate the efficacy and palatability of meloxicam 0.5mg/ml oral suspension, compared to ketoprofen tablets in cats suffering from painful acute locomotor disorders. This single blinded, positively-controlled, randomised, multicentre trial involved 121 client owned cats. Cats received either meloxicam (0.5mg/ml oral suspension) at 0.1mg/kg on day 1 followed by 0.05mg/kg q 24h on days 2-5, or ketoprofen 5mg tablets at 1.0mg/kg q 24h for 5 days. The efficacy of the two treatments was assessed subjectively by clinicians on day 6 using a clinical sum score (CSS).

The objective of this study was to compare the efficacy of meloxicam when given by intra-articular (IA) and subcutaneous (SC) routes of administration for postoperative analgesia versus a placebo for dogs undergoing stifle surgery. Twenty-five dogs with cranial cruciate ligament rupture (CCLR) were randomly assigned to one of three treatment groups, each with nine dogs, before surgical repair of twenty-seven stifles using a modified lateral retinacular imbrication technique. Group 1 dogs received IA administration of meloxicam and SC placebo. Group 2 dogs received IA placebo and SC meloxicam.

Objective: To evaluate the efficacy of S-adenosyl l-methionine (SAMe) in the treatment of clinically inferred canine osteoarthritis (OA). Study Design: Six weeks, double-blinded, placebo-controlled, clinical trial. Animals: Dogs (n=33) with clinical signs, history, and orthopedic exams consistent with OA. Methods: Dogs were block randomized by body condition score (<6/9, or ≥6/9) into either the placebo or SAMe group.

Objective: To determine the effect of unilateral condylectomy on dental occlusion in cats. Methods: Twelve feline cadaver heads were randomly submitted to either a right or left unilateral condylectomy of the temporo-mandibular joint. The distance between the mandibular and maxillary canine tooth was measured before (B0) and after the unilateral condylectomy (P0). A right or left latero--lateral standardised force (4 N) was applied to the mandibular mentus area before and after the surgical procedure. These measurements were analysed with a linear model for repeated measures.

Objective-To assess efficacy and tolerability of robenacoxib for control of pain and inflammation in dogs undergoing orthopedic surgery. Animals-140 client-owned dogs. Procedures-A multicenter, prospective, randomized, blinded field trial was conducted to compare robenacoxib (97 dogs) and meloxicam (43 dogs). After randomization, each dog received an initial dose (robenacoxib, 2 mg/kg; meloxicam, 0.2 mg/kg) via SC injection before surgery and daily doses (robenacoxib, 1 to 2 mg/kg; meloxicam, 0.1 mg/kg) administered orally for up to 15 days after surgery.

This report describes a 4 mo old intact male Akita that presented for evaluation of a life-long history of facial swelling and failure to thrive. Physical examination revealed an enlarged cranium with prominent bony swellings on the maxillary bone, excessive laxity and crepitus involving multiple joints, and proprioceptive deficits. Radiographs demonstrated multiple osseous abnormalities including endosteal thickening of the femurs and ilium. Necropsy revealed gross compression of the cerebellum and brainstem.

The authors compared the symptomatic effectiveness of a complex homeopathic preparation Zeel (1-3 tablets orally per day depending on body weight) to carprofen (4 mg/kg body weight) in dogs (n=68) aged >1 yr diagnosed with osteoarthritis in a multicenter, prospective, observational open-label cohort study in 12 German veterinary clinics. The active treatment period was 56 days. Symptomatic effectiveness, lameness, stiffness of movements, and pain on palpation were evaluated by treating veterinarians and owners.

Objective-To determine the relationship between serum cortisol concentration and pain severity as measured by force platform gait analysis in dogs with experimentally induced synovitis of the stifle joint. Animals-10 healthy hound-type dogs. Procedures-Dogs underwent 2 study phases. In the first phase, serum cortisol concentration, systolic arterial blood pressure, heart rate, and gait data were obtained at 0 (first sample), 2.5, 5, 7.5, and 10 hours.
