Evaluation of an ultrasound-guided freeze-core biopsy system for canine and feline brain tumors.

Objective: To determine if a single brain biopsy utilizing a freeze-core needle harvest system Cassi II under ultrasound guidance provides a diagnostic sample; to evaluate the technique's efficacy in procuring diagnostic samples in comparison with "open" surgical biopsies; and to describe intraoperative complications associated with the technique.

Study Design: Experimental clinical study.

Animals: Seventeen dogs and four cats with magnetic resonance imaging (MRI) diagnoses of readily surgically accessible intracranial masses.

Biopsy and histologic findings of the dura mater at the level of the foramen magnum in 121 CKCS with Chiari-like malformation.

To describe histopathologic features found in dural biopsies of Cavalier King Charles Spaniels (CKCS) with Chiari-like malformation (CM) and identify any associations between age, duration of clinical signs, syrinx location or syringomyelia (SM, and quality of life (QOL). The medical records of 121 consecutive client owned CKCS with CM and SM, confirmed by whole body magnetic resonance imaging (MRI), that underwent foramen magnum decompression (FMD) with cranioplasty and durectomy with biopsy from 2006 to 2016 were retrospectively reviewed. Dural biopsies were submitted to a board-certified veterinary pathologist for histopathologic interpretation.

Catastrophic Failures of the Tibial Post in a Bicruciate Substituting Total Knee Prosthesis.

Failure of the tibial post in a bicruciate substituting total knee prosthesis is a rare but catastrophic complication. The authors report 2 cases of a fracture of the polyethylene tibial post with subsequent episodes of knee subluxation. Prompt recognition and early revision of these complications are associated with a favorable early outcome.

Stop, Drop, and Roll! An Arthroscopic Technique for Anterior Glenoid Labrum Repair in the Lateral Decubitus Position.

This article describes a simple and reproducible arthroscopic technique for passing sutures in the shoulder glenoid labrum in the lateral decubitus position for orthopaedic surgeons. Communicating and teaching surgeons how to perform certain maneuvers with precision can be challenging at times. This technique will simplify and more efficiently communicate the advanced arthroscopic motor skill of passing sutures in the shoulder.

Patient Demographics and Anthropometric Measurements Predict Tibial and Femoral Component Sizing in Total Knee Arthroplasty.

Background: Accurate sizing is critical for the overall success of a total knee arthroplasty (TKA). This study's primary purpose was to investigate the ability to predict the tibial and femoral component size in a single implant system from patient demographics and anthropometric data. A secondary goal was to compare the predicted tibial and femoral component sizes from our statistical model with a previously validated electronic application used to predict the implant size.

Catastrophic failure of a dual mobility bearing in a revision total hip arthroplasty.

The following case demonstrates an example of a catastrophic failure of a dual mobility (DM) bearing used in the setting of a revision total hip arthroplasty for an acetabular component with an excessive abduction angle. Currently, in the literature, it has been demonstrated that DM bearings have decreased polyethylene wear at abduction angles up to 65°; however, this has only been shown in in vitro studies. To our knowledge, there have been no reports of in vivo DM bearings that have demonstrated these same results.

Histopathologic characteristics of biopsies from dogs undergoing surgery with concurrent gross splenic and hepatic masses: 125 cases (2012-2016).

Objective: To investigate the histopathologic characteristics of concurrent splenic and liver masses in dogs undergoing splenectomy and liver mass biopsy/resection. Medical records of 125 client-owned dogs found to have splenic mass or masses and a liver mass or masses during surgery were examined. Signalment (age, sex, breed), body weight, and results of histopathology were recorded for all dogs.

Medical infrared imaging and orthostatic analysis to determine lameness in the pelvic limbs of dogs.

Subtle lameness makes it difficult to ascertain which is the affected limb. A study was conducted to investigate a change in the thermal pattern and temperature of the thermal image of the paw print in a lame pelvic limb compared to a non-lame pelvic limb of dogs confirmed by orthostatic analysis. Fourteen client owned dogs with a unilateral pelvic limb lameness and 14 healthy employee dogs were examined and the pelvic limbs radiographed.

Atlantooccipital Overlap and Other Craniocervical Junction Abnormalities in Dogs.

The term craniocervical junction abnormality (CJA) is an umbrella term for a variety of malformations that occur in the craniocervical region. These abnormalities include Chiari-like malformation, atlantooccipital overlapping, atlantoaxial instability, occipitoatlantoaxial malformations, atlantoaxial dural bands, and dens abnormalities. Syringomyelia can occur secondary to any of these malformations or a combination.

Medical Infrared Imaging of Normal and Dysplastic Elbows in Dogs.

Objective: To investigate the ability of medical infrared imaging to differentiate between normal canine elbows and those with abnormal elbows (elbow dysplasia).

Study Design: Prospective cohort study.

Animals: Dogs with normal (n = 15) and abnormal (n = 14) elbows.

Medical infrared thermal imaging of cats with hyperthyroidism.

Objective: To determine the usefulness of medical infrared thermal imaging (MITI) as a screening tool for hyperthyroidism in cats, evaluate the need for hair clipping over the ventral aspect of the neck to achieve optimal images, and determine whether there is a change in thermal patterns at 1 and 3 months after radioactive sodium iodide I 131 treatment.

Animals: 17 cats with and 12 control cats without hyperthyroidism.

Procedures: All cats underwent MITI first with the hair present and then after the hair was clipped.

Medical infrared imaging (thermography) of type I thoracolumbar disk disease in chondrodystrophic dogs.

Objective: To: (1) determine the success of medical infrared imaging (MII) in identifying dogs with TLIVDD, (2) compare MII localization with magnetic resonance imaging (MRI) results and surgical findings, and (3) determine if the MII pattern returns to that of normal dogs 10 weeks after decompression surgery.

Study Design: Prospective case series.

Animals: Chondrodystrophic dogs (n = 58) with Type I TLIVDD and 14 chondrodystrophic dogs with no evidence of TLIVDD.

Diagnostic imaging of the canine stifle: a review.

The stifle joint, a common location for lameness in dogs, is a complex arrangement of osseous, articular, fibrocartilaginous, and ligamentous structures. The small size of its component structures, restricted joint space, and its intricate composition make successful diagnostic imaging a challenge. Different tissue types and their superimposition limit successful diagnostic imaging with a single modality.
