In Matz 2022 et al., on stapler size comparison, which stapler group had the highest mean initial leak pressure (ILP)?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. TA 30 V3 had the highest ILP at 181.5 mmHg, though differences were not statistically significant.
Incorrect. The correct answer is TA 30 V3 2.5 mm.
TA 30 V3 had the highest ILP at 181.5 mmHg, though differences were not statistically significant.

🔍 Key Findings

  • No significant difference in initial leak pressure (ILP) among TA 30 V3 2.5 mm, TA 60 3.5 mm, and TA 60 4.8 mm stapler sizes (P = .78).
  • All stapler types exceeded the physiological intraluminal pressure threshold (~25 mmHg), suggesting acceptable leak resistance.
  • Mean ILPs: TA 30 V3 (181.5 mmHg), TA 60 3.5 mm (112 mmHg), TA 60 4.8 mm (77.2 mmHg).
  • Leakage occurred at the staple line in 23 of 24 specimens; only one had ileal wall rupture.
  • No correlation found between ILP and cadaver weight, cecal wall thickness, or cecal length.
  • Cecal wall thickness averaged 4.9 mm, yet staple heights ranged only from 1.0–2.0 mm.
  • One specimen in each TA 60 group leaked near or below physiologic pressures, suggesting rare outliers.
  • Study supports clinical viability of all tested stapler sizes for canine typhlectomy, but highlights need for in vivo data on healing and complications.

In Zann 2023 et al., on proximal humeral OC, which diagnostic imaging modality measured greater lesion size compared to the other?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. CT measured significantly greater lesion width and depth than radiography (P = .001 and P = .038, respectively).
Incorrect. The correct answer is CT.
CT measured significantly greater lesion width and depth than radiography (P = .001 and P = .038, respectively).

🔍 Key Findings

  • All dogs developed progressive osteoarthritis (OA) after surgical debridement of proximal humeral OC.
  • Ipsilateral muscle atrophy and reduced shoulder range of motion were common, particularly in unilaterally affected dogs.
  • Arthroscopically, lesions showed incomplete cartilage infilling even years after surgery, averaging only ~37% infilling.
  • Synovitis was present in all joints, with moderate-to-severe hypertrophy and vascularity scores.
  • CT identified OC lesions as deeper and wider than radiography, and all affected joints had more advanced OA than contralateral limbs (P = .001 radiograph, P = .005 CT).
  • Kinetic gait analysis showed no significant differences in peak vertical force or impulse, but a subtle 4.4% asymmetric load reduction on the operated limb.
  • Median LOAD score was 6, indicating mild owner-perceived disability despite measurable clinical and imaging abnormalities.
  • Cartilage infilling was incomplete in all cases, with no lesion exceeding 60% restoration, raising questions about the healing potential of debridement alone.

In Bounds 2023 et al., on feline hip arthroscopy, which limb positioning provided optimal joint visualization?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. This positioning maximized joint space and visualization in all hips.
Incorrect. The correct answer is Neutral duction with 90° extension and traction.
This positioning maximized joint space and visualization in all hips.

🔍 Key Findings

  • Feline hip arthroscopy using a supratrochanteric lateral portal was feasible in all cadaveric hips studied.
  • All relevant intra-articular structures (femoral head, acetabulum, round ligament, joint capsule, transverse acetabular ligament, dorsal acetabular rim) were consistently visualized.
  • Optimal limb positioning (neutral abduction, 90° extension) significantly aided joint distraction and visualization.
  • Minor iatrogenic cartilage injury (ICI) occurred in all hips, typically partial-thickness abrasions; one hip had a full-thickness lesion.
  • Portal placement did not damage the sciatic nerve or caudal gluteal artery, with a mean distance of 4.3 ± 2 mm between the cannula and nerve.
  • Probe use improved visualization of the dorsal joint capsule and dorsal acetabular rim, though not essential.
  • Joint evaluation was also successful in hips with DJD, suggesting technique feasibility even in diseased joints.
  • Muscle trauma was minimal, with only mild impingement in a few specimens and no gross nerve or vessel injury.

In de Moya 2023 et al., on FGPP of femoral capital physeal/neck fractures, which major complication was reported following FGPP?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. One dog developed an intra-articular pin, requiring revision and ultimately FHO.
Incorrect. The correct answer is Intra-articular pin placement.
One dog developed an intra-articular pin, requiring revision and ultimately FHO.

🔍 Key Findings

  • 11 dogs, 13 fractures (mostly Salter-Harris type I) were repaired with FGPP using Kirschner wires.
  • 10/13 fractures achieved satisfactory healing with good limb function at ~43 days median follow-up.
  • Major complications occurred in 5 dogs: intra-articular pin placement, implant migration (2), implant failure with nonunion, and malunion.
  • 2 dogs presenting >15 days post-injury with radiographic remodeling were poor candidates → higher risk of nonunion/malunion.
  • Preoperative displacement was mostly mild (10/13 fractures); these had better outcomes than chronic or severely displaced cases.
  • Median surgical time: 60 minutes (range 45–75), all performed percutaneously without conversion to open.
  • Elective pin removal was performed in 5 cases; migration occurred with both short and long cut wires.
  • Femoral neck resorption (“apple-coring”) was rare (2/10 healed cases) and thought to be less frequent than after ORIF due to reduced vascular disruption.

In Knudsen 2024 et al., on CTA diagnosis, which imaging plane combination was used for multiplanar reconstruction of the canine stifle?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Multiplanar views included transverse, dorsal (frontal), and sagittal reconstructions.
Incorrect. The correct answer is Transverse, dorsal, sagittal.
Multiplanar views included transverse, dorsal (frontal), and sagittal reconstructions.

🔍 Key Findings

  • Multidetector CTA had high sensitivity (up to 100%) and specificity (up to 96%) for detecting medial meniscal tears in dogs.
  • Observer experience significantly influenced diagnostic accuracy, with more experienced observers showing higher agreement and better performance.
  • Training effect was evident, as less experienced observers improved between first and second readings.
  • Positive likelihood ratios ≥4.6 and negative likelihood ratios ≤0.08 were observed, suggesting CTA is clinically useful for confirming or ruling out meniscal injury.
  • CTA allowed identification of full and partial thickness lesions, with good visualization in sagittal, transverse, and frontal reconstructions.
  • Approximately 90% of menisci were correctly classified in second readings.
  • No adverse reactions were noted from the contrast injection; sedation was used instead of general anesthesia.
  • CTA was less invasive and potentially more cost-effective compared to arthroscopy, especially in settings without MRI access.

In Marturello 2023 et al., on 3D-printed humeral models, which anatomical region had the **highest model accuracy** across all printer types?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Humeral condyle replicas were consistently within 0.5 mm of cadaveric measurements, the most accurate across the study.
Incorrect. The correct answer is Humeral condyle.
Humeral condyle replicas were consistently within 0.5 mm of cadaveric measurements, the most accurate across the study.

🔍 Key Findings

  • 3D-printed models using desktop printers (FDM, LFS) showed submillimetric accuracy, comparable to or better than industrial-grade PJP printers.
  • Bone size had a greater effect on print accuracy than printer type, especially in proximal humerus regions.
  • The humeral condyle region showed the greatest model accuracy, with mean differences under 0.5 mm, regardless of printer.
  • Models tended to be slightly smaller than cadaveric bones, potentially due to systematic underestimation during printing.
  • FDM printer provided the highest accuracy at the humeral condyle in medium-sized bones (+0.09 mm).
  • LFS printer produced prints faster and more reliably than FDM, although both had comparable dimensional accuracy.
  • Statistically significant differences existed, but all were submillimetric and unlikely to impact surgical outcomes.
  • Desktop printers are suitable for surgical planning, including plate pre-contouring and patient-specific instrumentation.

In Sadowitz 2023 et al., on screw angle & speed, what clinical recommendation is supported to reduce TCF risk?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. The authors recommend slow, coaxial screw insertion to minimize the risk of transcortical fractures.
Incorrect. The correct answer is Insert screws slowly and coaxially to the pilot hole.
The authors recommend slow, coaxial screw insertion to minimize the risk of transcortical fractures.

🔍 Key Findings

  • TCF risk increased significantly with 10° insertion angle at both 650 rpm (12.5%) and 1350 rpm (17.5%), compared to 0% in the control group (0° at 650 rpm).
  • Hand insertion at 10° angle resulted in only 3.75% TCF rate, suggesting lower insertion speed reduces risk.
  • No TCFs occurred when screws were inserted coaxially (0°) at either 650 or 1350 rpm, indicating angle is a critical factor.
  • Screw speed alone did not increase TCF risk unless combined with off-axis insertion.
  • Radiographically detectable TCFs were only considered; actual rates may be higher with direct bone inspection.
  • Cutting flutes engaging undrilled bone during off-axis insertion likely contribute to TCF formation.
  • Clinical implication: Ensure screws are inserted coaxially and at lower speeds to reduce TCF risk during procedures like TPLO.
  • Statistically significant differences were found between control and high-angle insertion groups: Group C (p = .001), Group E (p < .001).

In Trefny 2025 et al., on locking plate biomechanics, how was strain distribution measured in the plates?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Strain was measured via 3D digital image correlation at predefined ROIs.
Incorrect. The correct answer is 3D digital image correlation.
Strain was measured via 3D digital image correlation at predefined ROIs.

🔍 Key Findings

  • Short working length constructs had significantly higher stiffness and lower strain than long constructs in compression bending (p = 0.0172).
  • In tension bending, short constructs also had higher precontact stiffness and lower strain, but this reversed after transcortical contact (~150 N).
  • Transcortical contact increased stiffness only in long constructs, producing a bilinear load-displacement curve.
  • Postcontact stiffness was higher in long constructs, but this may not reflect clinical benefit due to risks of high interfragmentary strain.
  • Short working length reduced strain at multiple ROIs under both loading conditions, including over fracture gap (Tables 1–3).
  • Increased working length promoted stress concentration and deformation, especially in compression bending.
  • In vitro benefits of long constructs (via contact stability) may not translate to healing, as repetitive loading could increase plate strain and bone resorption.
  • Plate strain was effectively mapped using 3D digital image correlation, confirming regional strain differences between configurations.

In Davies 2024 et al., on lymphaticovenous anastomosis, what intervention resolved partial occlusion of the thoracic duct after MAC coupling in one cat?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Twisting of the TD was corrected by anchoring it with a tacking suture.
Incorrect. The correct answer is Tacking suture between TD and thoracic wall.
Twisting of the TD was corrected by anchoring it with a tacking suture.

🔍 Key Findings

  • Lymphaticovenous anastomosis (TD to AV) was successfully performed in all 8 feline cadavers using a microvascular anastomotic coupler (MAC).
  • Anastomotic patency was confirmed intraoperatively and postoperatively in 7/8 cats via contrast lymphography or retrograde venography.
  • Dissection and anastomosis took a median of 120 minutes, with minimal technical complications.
  • A 1.5 mm MAC was used in 6 cats, and a 2.0 mm in 2 cats; TD diameter ranged 1.0–1.5 mm, AV up to 2.25 mm.
  • Challenges included vessel twisting and luminal patency issues, resolved intraoperatively with minor adjustments (e.g., repeat pinning, tacking suture).
  • MAC use eliminated need for hand-suturing, lowering skill demands but requiring precise alignment.
  • Technique provides direct lymphatic-to-venous drainage, potentially reducing the stimulus for collateral vessel formation.
  • May serve as a future treatment option for feline idiopathic chylothorax, warranting further in vivo studies.
