Chapter
This chapter discusses conditions affecting the tarsal region (i.e. any of the structures affecting the tarsal joint and surrounding area). A brief discussion of the clinically relevant local anatomy is followed by a detailed description of the history, physical examination, and diagnostic findings typically found in patients presenting with pathol...
Article
Nontraumatic spontaneous pneumoperitoneum suggests the presence of gastrointestinal perforation; early detection can be lifesaving. Horizontal beam projections have been reported to be more sensitive than standard radiographic views for detecting small volumes of free peritoneal gas. This prospective, experimental, analytical study compared both le...
Article
Two male intact dwarf rabbits (Oryctolagus cuniculus), 20 and 26 months old, were diagnosed with traumatic long bone fractures of the radius/ulna and tibia, respectively. Transfixation pin splinting, a technique adapted from large animal orthopedics, was used to stabilize the long bone fractures in both rabbits. Bony union with return to normal lim...
Article
In properly selected dogs, juvenile pubic symphysiodesis improves joint congruity, decreases hip laxity, and can reverse or prevent progression of degenerative joint disease in the hips. To be effective, surgery must be done at a young age and in hips that are only mildly to moderately lax. Juvenile pubic symphysiodesis is best viewed more as a pre...

The objective of this study was to determine whether the protein Zhangfei could suppress the unfolded protein response (UPR) and growth of osteosarcoma cells. Dog (D-17) and a human (Saos-2) osteosarcoma cells were infected with adenovirus vectors expressing either Zhangfei or the control protein beta- galactosidase. We monitored cell growth as wel...

Objectives: The primary objective was to develop a repeatable radiographic technique for assessment of cranial tibial subluxation (CTS) and test the intra-observer and inter-observer repeatability of the chosen landmarks. A secondary objective was to determine the effects of digital radiographic magnification on CTS measurement repeatability. Met...

The aim of this report was to describe the clinical signs, diagnostic approach, treatment and outcome in the case of a tiger with a deformity of the paw. A 1.5-year-old tiger (Panthera tigris) was presented with lameness of the left thoracic limb. A deformity involving the first and second metacarpal bones, and a soft tissue separation between the...

Movie 2. Observe the marked improvement of the locomotion after 10 days after surgery.
Data
Movie 1. Observe the lameness of the left thoracic limb in a tiger with ectrodactyly in the left front paw before the surgery.

For the purpose of determining factors associated with ovulation induction in rabbits, there is a need to examine the ovaries in a serial fashion. To this end, a study was designed to develop an approach that would permit serial evaluation of ovarian structures in vivo using ultrasound biomicroscopy (UBM) while preserving ovarian function in rabbit...

To measure one and two year effects of juvenile pubic symphysiodesis (JPS) in puppies defined as 'at-risk' for canine hip dysplasia (CHD) using the following objective hip conformation criteria: Acetabular angle (AA), dorsal acetabular rim angle (DARA) and hip laxity (PennHIP© distraction index (DI). Controlled clinical case study. Thirty-nine dysp...

Chronic tendinopathy injuries to the canine common calcaneal tendon are relatively common in large breed dogs and typically affect the distal portion of the tendon. In humans, poor blood supply, biomechanical faults, poor training methods and fluoroquinolone administration have all been linked with the development of Achilles tendinopathy. The most...

A chronic, partial mesenteric volvulus was found on laparotomy of an adult Bernese mountain dog with a 4-month history of intermittent vomiting, diarrhea, and weight loss. The dog had elevated cholestatic and hepatocellular leakage enzymes, increased bile acids, azotemia, isosthenuria, and a hypokalemic, hypochloremic, metabolic alkalosis. The dog...

An 8-year-old, castrated male golden retriever was referred for lethargy and inappetance. Severe pain was elicited on palpation of the left temporomandibular joint region. Computed tomography revealed aggressive bone destruction of the left bulla. Squamous cell carcinoma was diagnosed. Malignant tumor in the canine middle ear is rare.
