OBJECTIVE: To (1) determine suction tip (intermittent and continuous mode) contamination rate in orthopedic surgery in dogs and cats; (2) examine the effect of surgical time on contamination; and (3) report bacteria isolated. STUDY DESIGN: Clinical study. SAMPLE POPULATION: Clean orthopedic surgeries (n = 50). METHODS: Surgical procedures were assigned to 1 of 2 groups: (1) continuous (n = 25) or (2) intermittent suction (n = 25). A control suction was operated in each surgery.

Objectives: To compare the improvement in degree of lameness following surgical repair of cranial cruciate ligament rupture in dogs using computer-assisted gait analysis. Methods: Two groups of 14 dogs were used. One group was treated by a capsular-fascial imbrication method, and the other group by tibial plateau levelling osteotomy (TPLO). All dogs underwent gait analysis prior to surgery, as well as at four days, four weeks, and four months after surgery.

Objectives: This study investigated cemented fixation of the tibial component from a canine total knee replacement preclinical model. The objective was to determine the local morphology at the material interfaces (implant, cement, bone) and the local relative micro- motion due to functional loading following in vivo service. Methods: Five skeletally mature research dogs underwent unilateral total knee replacement using a cemented implant system with a polyethylene (PE) monobloc tibial component. Use of the implanted limb was assessed by pressure-sensitive walkway analysis.

Objective-To assess the effect of computed tomography (CT) scan protocols (radiation amounts) and fabrication methods on biomodel accuracy and variability. Sample-Cadaveric femur of a Basset Hound. Procedures-Retroreconstructions (n = 158) were performed of 16 original scans and were visually inspected to select 17 scans to be used for biomodel fabrication. Biomodels of the 17 scans were made in triplicate by use of 3 freeform fabrication processes (stereolithography, fused deposition modeling, and 3-D printing) for 153 models.

Objective: To assess current habits for surgical hand preparation among veterinary surgical specialists and to compare data with current guidelines for hand asepsis techniques. Study design: Survey of veterinary surgical specialists. Sample Population: Diplomates of the American (ACVS) and European Colleges of Veterinary Surgeons (ECVS). Methods: An internet-based survey of hand preparation methods before surgical procedures was conducted of 1300 listed ACVS and ECVS Diplomates. Results: A 42.6% response rate was obtained.

Objective-To assess validity and reliability for a visual analogue scale (VAS) used by owners to measure chronic pain in their osteoarthritic dogs. Sample-68, 61, and 34 owners who completed a questionnaire. Procedures-Owners answered questionnaires at 5 time points. Criterion validity of the VAS was evaluated for all dogs in the intended-to-treat population by correlating scores for the VAS with scores for the validated Helsinki Chronic Pain Index (HCPI) and a relative quality-of-life scale. Intraclass correlation was used to assess repeatability of the pain VAS at 2 baseline evaluations.

OBJECTIVE: To quantitatively assess a surgical "learning curve" using the cumulative summation (CUSUM) score technique. Study
DESIGN: Application of a CUSUM technique to a consecutive series of surgical cases.
ANIMALS: Consecutive primary cemented total hip replacement (THR; n=116) in 106 dogs.
METHODS: Records of all dogs that had primary canine THR were reviewed. Data retrieved included date of surgery, postoperative complications, and duration of follow-up. The 12-week outcome was analyzed graphically and with a CUSUM technique.

OBJECTIVE: To determine the items (question topics) for a subjective instrument to assess degenerative joint disease (DJD)-associated chronic pain in cats and determine the instrument design most appropriate for use by cat owners.
ANIMALS: 100 randomly selected client-owned cats from 6 months to 20 years old.
