Effect of needle gauge on pain and specimen quality of ultrasound-guided fine needle sampling without aspiration of the canine spleen.

Modifications of splenic parenchyma are common ultrasonographic findings in dogs. Splenic fine needle aspiration (FNA) is a rapid, safe procedure, routinely performed in veterinary institutions. However, 22-gauge (G) needle usually reported is selected according to general practice and the most appropriate needle size to be used remains unclear.

Lumbosacral endplate contour defect is frequently observed concurrent with other lumbosacral abnormalities on spinal CT of French Bulldogs.

Lumbosacral osteochondrosis has been previously described in large breed dogs with variable clinical signs. Its CT features are a contour defect at the dorsal aspect of either vertebral endplate, commonly with an adjacent fragment. Descriptions of this condition have not been previously published in an increasingly popular breed, French Bulldogs.

Trochlear Shape and Patient-Reported Outcomes After Arthroscopic Deepening Trochleoplasty and Medial Patellofemoral Ligament Reconstruction: A Retrospective Cohort Study Including MRI Assessments of the Trochlear Groove.

Background: Sparse objective data are available documenting changes of trochlear shape after trochleoplasty.

Purpose/hypothesis: The purpose was to investigate whether standardized magnetic resonance imaging (MRI) measurements that characterize trochlear dysplasia (TD) change significantly after arthroscopic deepening trochleoplasty (ADT) combined with medial patellofemoral ligament (MPFL) reconstruction. It was hypothesized that MRI measurements would approximate normal values.

Executive-centered AI? Designing predictive systems for the public sector.

Recent policies and research articles call for turning AI into a form of IA ('intelligence augmentation'), by envisioning systems that center on and enhance humans. Based on a field study at an AI company, this article studies how AI is performed as developers enact two predictive systems along with stakeholders in public sector accounting and public sector healthcare. Inspired by STS theories about values in design, we analyze our empirical data focusing especially on how objectives, structured performances, and divisions of labor are built into the two systems and at whose expense.

Effect of Medialization of the Trochlear Groove and Lateralization of the Tibial Tubercle on TT-TG Distance: A Cross-sectional Study of Dysplastic and Nondysplastic Knees.

Background: Tibial tubercle-trochlear groove (TT-TG) distance is often used as a measure of lateralization of the TT and is important for surgical planning.

Purpose: To investigate if increased TT-TG distance measured on axial magnetic resonance images is due to lateralization of the TT or medialization of the TG.

Study Design: Cross-sectional study; Level of evidence, 3.

[Joint-preserving surgery in hip and knee and development of secondary osteoarthritis].

The purpose of this review was to elucidate if surgery can prevent secondary osteoarthritis (OA) in hip dysplasia, femoroacetabular impingement syndrome, varus malalignment of the knee, patella instability, anterior cruciate ligament injury and intra-articular fracture of the knee or hip. In conclusion, there is evidence that surgery for intra articular fracture of the knee or hip reduces the risk of secondary OA. There is a lack of prospective comparative studies for the remaining investigated conditions and as such no convincing evidence that surgery reduces the risk of secondary OA.
