In Mazdarani 2025 et al., on simulated muscle loading, which model showed the lowest muscle force ratios (quadriceps:gastrocnemius)?
🔍 Key Findings
- Simulated quadriceps and gastrocnemius forces increased proportionally with axial load in all three femoral fixation models.
- Model 2 (rigid fixation) resulted in subphysiologic quadriceps forces and abnormally high gastrocnemius forces, reducing model fidelity.
- Models 1 and 3 (with hip mobility) produced more physiologic quadriceps and force ratios, especially under 30–40% bodyweight loads.
- Force ratios were significantly lower in rigid fixation (Model 2) compared to hip-mobile models (p = .007), suggesting model design affects simulated muscle coordination.
- Joint angles (stifle and hock) remained within acceptable limits, though slight flexion occurred with increasing load.
- Relative foot position differed by ~3.9 mm between models 2 and 3, with model 2 showing a more caudal position.
- Model 3 preserved benefits of hip mobility while allowing radiographic documentation, making it a preferred setup for future studies.
- The study suggests that models used in feline stifle stabilization research may underestimate physiologic forces, especially with rigid fixation designs.

In Philips 2025 et al., on radiographic IAIP detection, which implant direction was more likely to be misclassified as penetrating the joint?
🔍 Key Findings
Overall accuracy of radiography to detect IAIP: 77.9%
Sensitivity: 97.2%
Specificity: 67.6%
False positive rate: 32.4% of non-penetrating implants were misclassified as penetrating
Implants directed toward the lateral tibial condyle had higher misclassification (23.8%) than medial (8.3%)
Most accurate detection: Implants placed 2 mm into the joint (97.2% correct classification)
Least agreement: For implants placed at 0 mm (subchondral level), especially lateral (AC1 = 0.48)
No palpable abnormalities (e.g., crepitus) observed during ROM for any group
No significant difference in detection by specialty field or reviewer qualification
Suggests radiographic misclassification risk and supports considering CT/fluoroscopy in equivocal cases

In Nicolas 2024 et al., what surgical technique was used to decompress the foramen at T1–2?
🔍 Key Findings Summary
- The lateral approach via scapular osteotomy allowed safe access to the T1-2 foramen in a French Bulldog with foraminal disc extrusion.
- A mini-hemilaminectomy was performed, preserving articular facets.
- The dog had no neurologic deficits postoperatively, returned to ambulation within 24 hours, and was discharged in 3 days.
- At 10 months, CT confirmed excellent scapular healing and no recurrence.
- Double 2.4-mm locking plates provided stable fixation across the scapular spine.
- The technique avoided thoracic entry or dorsal spine dissection, suggesting a less invasive alternative for select T1-2 foraminal cases.

In Baldo Clemot 2026 et al., on dynamic MRI in DLSS, what was the most consistent finding in the flexed position compared to neutral?
🔍 Key Findings
- Flexed MRI reduced IVD protrusion, foraminal stenosis, and VBLF significantly compared to neutral position.
- No dogs had persistent cauda equina compression or foraminal occlusion in the flexed position.
- Protrusion decreased by ~50% in flexion (PRCR and PACR reductions of 49.3% and 53.1%, respectively).
- Degree of IVD protrusion correlated with IVD degeneration but not spondylosis.
- Spondylosis did not limit flexion or affect decompression response.
- Complete vertebral canal occlusion resolved in all cases when LSJ was flexed.
- Indirect decompression via distraction may negate the need for laminectomy/discectomy, unless placing an IVD spacer.
- Findings question the routine use of decompressive surgery with distraction-stabilization in DLSS when good flexion is achieved.

In Parlier 2024 et al., on insufflation effects on portal pressure in dogs, what was the observed change in portal pressure at 14 mmHg insufflation?
🔍 Key Findings
- Portal pressure increased proportionally with insufflation pressure: 38% at 6 mmHg, 95% at 10 mmHg, and 175% at 14 mmHg.
- Exponential model: average increase of 7.45% per mmHg of insufflation pressure (CI: 4.7–10.2%).
- No systemic hemodynamic adverse effects were observed; MAP remained >60 mmHg throughout.
- Portal hypertension threshold (15 mmHg) predicted at ~6.4 mmHg insufflation pressure.
- No statistical impact from patient weight, pressure-to-weight ratio, or order of insufflation rounds.
- Measurement technique was feasible and safe, with only minor challenges (e.g., catheter kinking).
- The study supports use of the lowest insufflation pressure needed for visualization to avoid portal hypertension.
- Baseline portal pressures returned after desufflation, supporting comparison pre- and post-attenuation.

In Dickerson 2023 et al., on surgical outcomes in hepatic abscessation, what was the most commonly identified bacterial isolate?
🔍 Key Findings
- Liver lobectomy was the most common treatment (27/36 dogs), with multiple lobes removed in ~1/3 of cases.
- Septic peritonitis was present in 21/23 sampled dogs, making it a frequent complication.
- Perioperative complications occurred in 21/36 dogs, including aspiration pneumonia, pancreatitis, and acute kidney injury.
- Intraoperative hypotension was common (32/36), often requiring vasopressors or colloids.
- Mortality prior to discharge was 21% (8/38), with deaths related to sepsis, aspiration pneumonia, and multi-organ dysfunction.
- Median survival time was 638 days in dogs surviving to discharge.
- No recurrence of hepatic abscessation was observed in the surviving population.
- E. coli and Clostridium spp. were the most commonly cultured organisms, often as single-agent infections.

In Lee 2022 et al., on TPLO accuracy, what was observed regarding postoperative TPA in both groups?
🔍 Key Findings
- 3D-printed TPLO guides significantly reduced osteotomy inclination angle in both bone models and cadaver limbs compared to jig alone (P < .001).
- Torsional deformities were lower when the 3D-printed guide was used in bone models (P < .001), but not significantly different in cadavers.
- Angular deformities were significantly reduced in cadavers using 3D-printed guides (P < .001).
- Proximal jig pin angulation was more accurate with the guide in cadavers (P < .001); not significant in bone models.
- Medial cortex damage was substantially reduced in bone models when the 3D-printed guide was used (P < .001).
- Postoperative tibial plateau angle (TPA) did not differ significantly between groups, suggesting that clinical alignment can still be achieved without the guide.
- Clinical significance of improved metrics is uncertain, but improved precision may reduce surgical complications.
- 3D guide design allowed direct placement of jig and bone plate, potentially improving workflow and safety.

🔍 Key Findings
- Hepatic venous drainage patterns vary widely across all lobes, especially the left lateral lobe.
- Right lateral lobe had a median of 2 vessels draining directly into the caudal vena cava (CVC); range: 1–4.
- Caudate process of caudate lobe had the most variability: 1–5 vessels draining into the CVC; 2 vessels was most common (54.5%).
- Left lateral lobe drained via 2–8 veins into the left hepatic vein (LHV), with 3 veins most common (31.2%).
- Left medial lobe typically had 1 vein draining into the LHV (61% of dogs).
- Papillary process drained into the LHV in 93.5% of cases; 6.5% drained directly to the CVC.
- Quadrate lobe always had 1 vessel draining either directly to the CVC or via the LHV.
- CTA revealed more variations than previously described in plastinated or cadaveric studies, highlighting its superior value in surgical planning.
