Study Design: Observational study.

Sample: Radiographic images of 73 hip joints from 60 dogs with cementless cups.

Evaluation of Osteotomy Healing in Boxer Dogs Undergoing Tibial Plateau Levelling Osteotomy Using Two Radiographic Scoring Systems.

Objective:  The aim of this study was to (1) compare 5-point and 10-point bone healing radiographic scoring systems using postoperative tibial plateau levelling osteotomy (TPLO) radiographs and (2) determine whether Boxer osteotomy healing time differs from age-matched Labrador Retrievers.

Study Design:  This was a multicentre retrospective study. Fifty-eight client-owned dogs undergoing TPLO (29 Boxers and 29 Labrador Retrievers) were included.

Subtotal Pericardiectomy and Epicardiectomy for Treatment of Septic Pericarditis and Constrictive Epicarditis in a Dog.

A 1 yr old, 1.7 kg, spayed female Chihuahua was presented for respiratory distress and an enlarged cardiac silhouette as seen on thoracic radiographs. Echocardiogram revealed pericardial effusion and cardiac tamponade.

Number of previous surgeries and antibiotic resistance decreases the success of local administration of antibiotic-impregnated poloxamer 407 hydrogel when managing orthopedic surgical site infections in dogs.

Objective: To report the outcome of locally administered antibiotic-impregnated poloxamer 407 (P407) hydrogel in dogs diagnosed with orthopedic surgical site infections (SSIs) and to identify risk factors for treatment failure.

Animals: 34 client-owned dogs diagnosed with an orthopedic surgical site infection treated with local antibiotic-impregnated P407 hydrogel.

Procedures: Medical records were reviewed of dogs receiving antibiotic-impregnated P407 hydrogel for an active orthopedic SSI between March 2018 and December 2020.

Metal reactivity is present in dogs with tibial plateau leveling osteotomy and total hip replacement implants.

Objective: Determine whether dogs with well-functioning orthopedic metal implants can develop metal reactivity.

Sample: Client-owned dogs that had tibial plateau leveling osteotomy (TPLO) or total hip replacement (THR) implants for 12 months or more and control dogs with no implants.

Procedures: Lymphocyte transformation testing was performed by exposing peripheral blood lymphocytes to nickel (Ni), chromium (Cr), cobalt (Co), or a combination of these metals.

Delayed union, non-union and mal-union in 442 dogs.

Objectives: (1) To estimate the prevalence of delayed union, non-union and mal-union in canine fractures; (2) to describe fracture, demographic, and treatment characteristics for these outcomes; (3) to identify risk factors for delayed or non-union.

Study Design: Retrospective study.

Sample Population: Four hundred and forty two dogs (461 fractures).

Results of using multiplanar reconstructed CT images for assessing elbow joint osteoarthritis in dogs are consistent with results of radiographic assessment.

Objective: To compare osteoarthritis scores assigned through radiographic evaluation of 18 anatomic regions in the elbow joint with scores assigned through evaluation of 3-D maximum intensity projection (MIP), 3-D surface rendering (TSR), and multiplanar reconstructed (MPR) CT images, and to evaluate intraobserver and interobserver agreement of radiographic and CT scoring.

Sample: Radiographic and CT images of 39 elbow joints in 20 dogs.

Procedures: Images were anonymized and graded independently by 5 observers.

Long-Term Assessment of Bone Regeneration in Nonunion Fractures Treated with Compression-Resistant Matrix and Recombinant Human Bone Morphogenetic Protein-2 in Dogs.

Objective:  The aim of this study was to assess bone density, bone architecture and clinical function of canine nonunion distal appendicular long bone fractures with a defect treated with fixation, compression-resistant matrix and recombinant human bone morphogenetic protein-2 (rhBMP-2).

Study Design:  Prospective cohort study with dogs at least 1-year post treatment. Computed tomography was performed and quantitative measurements from previous fracture sites were compared with measurements from contralateral limbs.

Tissue Engineering of Canine Cartilage from Surgically Debrided Osteochondritis Dissecans Fragments.

This study in dogs explored the feasibility of using cartilage fragments removed and discarded during routine palliative surgery for osteochondritis dissecans (OCD) as a source of primary chondrocytes for scaffold-free cartilage tissue-engineering. Primary chondrocytes were obtained from three OCD donors and one age-matched healthy articular cartilage (HAC) donor. After monolayer expansion of primary cells, a three-dimensional spherical suspension culture was implemented.

Training Surgical Residents Utilizing an Animal Shelter Fracture Program.

Working relationships between veterinary medical teaching hospitals, animal shelters, and rescue groups are one way to increase veterinary students' and residents' hands-on training. The goal of this study is to describe the use of a shelter fracture program to improve the surgical skills of surgical residents. In this program, the participating shelter and rescue organizations electronically submit cases.

Influence of interlocking thread screws to repair simulated adult canine humeral condylar fractures.

Objective: To determine the influence of interlocking screw threads on the biomechanical properties of repaired canine humeral condylar fractures.

Study Design: Ex vivo biomechanical study.

Sample Population: Thirty-six humeral condyles.

Comparison of 18F-sodium fluoride positron emission tomography and CT: An exploratory study in 12 dogs with elbow pain.

18F-Sodium Fluoride (18F-NaF) positron emission tomography (PET) provides high resolution functional information about bone activity and can be fused with CT images to improve three-dimensional localization and characterization of lesions. This prospective, observational study assessed 18F-NaF PET-CT for imaging of canine elbows, compared PET with CT findings, and assessed correlation with lameness. Twelve patients with elbow pain were included.

Comparison of needle arthroscopy, traditional arthroscopy, and computed tomography for the evaluation of medial coronoid disease in the canine elbow.

Objective: To evaluate the diagnostic value of still images of needle arthroscopy (SNAR), still images of traditional arthroscopy (STAR), and computed tomography (CT) to diagnose medial coronoid process (MCP) pathology.

Study Design: Prospective clinical trial.

Animals: Dogs (n = 17) presented for evaluation of elbow dysplasia.
