A generic precurved interlocking nail is more compatible with femoral and tibial morphology than a straight nail in dogs.

Objective: To study the morphology of canine and feline femurs and tibias in lateral radiographic projections and assess their compatibility with either a straight or a curved full-length interlocking nail (ILN).

Methods: Lateral projection radiographs of 50 tibias and 50 femurs (10 cats and 40 dogs per bone) were used to measure the minimum and maximum radius of curvature of an ILN compatible with each bone. These radii were defined by cranial and caudal endosteal points at the proximal entry point of the nail, at the isthmus, and at the most distal point of the ILN insertion into the femoral or tibial metaphysis.

Retrospective study of the early clinical experience with a precontoured angle-stable interlocking nail for fracture repair in dogs and cats.

Objective: To report indications, outcomes, and complications with a precontoured angle-stable interlocking nail (CAS-ILN).

Animals: 90 client-owned animals.

Methods: Dogs and cats treated with the CAS-ILN between 2020 and 2022 were retrospectively reviewed.

Computed tomographic assessment of retrograde urohydropropulsion in male dogs and prediction of stone composition using Hounsfield unit in dogs and cats.

Background: Persistent uroliths after a cystotomy in dogs are a common cause of surgical failure.

Objectives: This study examined the following: the success rate of retrograde urohydropropulsion in male dogs using non-enhanced computed tomography (CT), whether the CT mean beam attenuation values in Hounsfield Units (mHU) measured could predict the urolithiasis composition and whether the selected reconstruction kernel may influence the measured mHU.

Methods: All dogs and cats that presented with lower urinary tract uroliths and had a non-enhanced CT preceding surgery were included.

Ultrasonographic and computed tomographic features of a true gastro-gastric intussusception with concurrent foreign bodies in a dog.

A 2-year-old intact male Cane Corso dog was presented for acute weakness, vomiting, and diarrhea. Abdominal ultrasound revealed the stomach had severe wall edema and a target appearance. Computed tomography was consistent with a gastro-gastric intussusception and concurrent mineral-like gastric foreign bodies.

Radiographically confirmed outcomes after fracture repair with a PLS polyaxial locking system in 40 dogs and cats.

Objective: To report radiographic findings and complications after fracture repair with a new polyaxial locking plate system (PLS polyaxial locking system; Aesculap/B Braun, Tuttlingen, Germany) in dogs and cats.

Study Design: Retrospective case review from four veterinary practices.

Sample Population: Twenty-six dogs and 14 cats (40 long bone fractures).

Effect of Intravenous Morphine Injection on Neurological Examination of Dogs With Thoracolumbar Intervertebral Disk Extrusion.

We aimed to determine the effect of intravenous morphine injection on the modified Frankel scores of dogs with thoracolumbar intervertebral disk extrusion (IVDE). This was a prospective, blinded, randomized, and placebo-controlled study. We included dogs with a presumptive diagnosis of thoracolumbar IVDE that did not undergo analgesic, anti-inflammatory, or sedative treatment within the last 12 h.

Reproducibility, Accuracy and Effect of Autoclave Sterilization on a Thermoplastic Three-Dimensional Model Printed by a Desktop Fused Deposition Modelling Three-Dimensional Printer.

Objectives:  The main purpose of this study was to determine the reproducibility and accuracy of a three-dimensional (3D) bone model printed on a desktop 3D-printer based on fused deposition modelling (FDM) technology with polylactic acid (PLA) and the effect of autoclave sterilization on the printed models.

Methods:  Computed tomographic images of the tibia were obtained from 10 feline cadavers, used to create a bone surface-rendering file and sent to the 3D printing software. Right and left tibias were each printed five times with the FDM desktop 3D printer using PLA plastic material.

Ultrasonography is more accurate than percutaneous palpation for identifying targeted thoracolumbar intervertebral disc spaces in dogs.

During minimally invasive spinal surgery, correct identification of the affected intervertebral disc space is critical. Percutaneous palpation is commonly used, but results may be unreliable. Fluoroscopy is the gold standard but can be cumbersome and exposes operators to ionizing radiation.

Effectiveness of a bipolar vessel sealant device for ovariohysterectomy in cats with pyometra.

Objectives: The objective was to describe the use of a bipolar vessel sealant device for complete ovariohysterectomy in cats (ie, removal of both the ovarian pedicle and the uterine body and vessels) and to report on the feasibility of ovariohysterectomy in cats with pyometra.

Methods: Cats with confirmed pyometra and whose owners agreed to the surgical procedure were prospectively included in the study. Ovaries were visualised and the vessel sealant device was used to coagulate and cut the suspensory ligament, the ovarian pedicle and the broad ligament up to the level of the uterine body.

Stabilization of Olecranon Fractures by Tension Band Wiring or Plate Osteosynthesis: A Retrospective Study of 41 Cases.

Objectives:  This article aimed to describe olecranon fracture in dogs and cats and their stabilization with tension band wiring or plate osteosynthesis, and to evaluate complications associated with each technique.

Methods:  Medical records of cats and dogs that had been surgically treated for olecranon fractures with either tension band wiring or plate osteosynthesis were retrospectively reviewed. The surgical technique, complications and long-term outcomes were assessed.

Age-related thoracic radiographic changes in golden and labrador retriever muscular dystrophy.

Golden retriever and Labrador retriever muscular dystrophy are inherited progressive degenerative myopathies that are used as models of Duchenne muscular dystrophy in man. Thoracic lesions were reported to be the most consistent radiographic finding in golden retriever dogs in a study where radiographs were performed at a single-time point. Muscular dystrophy worsens clinically over time and longitudinal studies in dogs are lacking.

The influence of Bone Morphogenic Protein-2 on the consolidation phase in a distraction osteogenesis model.

We asked whether locally applied recombinant-Bone Morphogenic Protein-2 (rh-BMP-2) with an absorbable Type I collagen sponge (ACS) carrier could enhance the consolidation phase in a callotasis model. We performed unilateral transverse osteotomy of the tibia in 21 immature male rabbits. After a latency period of 7 days, a 3-weeks distraction was begun at a rate of 0.

One stage functional end-to-end stapled intestinal anastomosis and resection performed by nonexpert surgeons for the treatment of small intestinal obstruction in 30 dogs.

Objectives: To describe stapled 1-stage functional end-to-end intestinal anastomosis for treatment of small intestinal obstruction in dogs and evaluate outcome when the technique is performed by nonexpert surgeons after limited training in the technique.

Study Design: Case series.

Animals: Dogs (n=30) with intestinal lesions requiring an enterectomy.

Fungal rhinosinusitis caused by Scedosporium apiospermum in a cat.

A 3-year-old neutered male Bengal cat with a history of chronic mucopurulent bilateral nasal discharge and sneezing was diagnosed with severe fungal rhinosinusitis. A diagnosis was obtained after computer tomography imaging, histopathological examination and fungal culture. The mold Scedosporium apiospermum was identified as the aetiological agent.

Successful treatment of cervical spinal epidural empyema secondary to grass awn migration in a cat.

Spinal epidural empyema (SEE) represents a severe pyogenic infection of the epidural space. Clinical signs of the disease are non-specific--increased body temperature, intense neck pain, neurological signs of a transverse myelopathy--and can lead to severe and permanent neurological deficits. This report describes the diagnosis and successful surgical treatment of cervical SEE secondary to grass awn migration in a cat.
