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.

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.
