In Williams 2024 et al., on adrenaline use in maxillary nerve blocks, which breed showed significantly higher **normalized hemorrhage** despite adrenaline use?
🔍 Key Findings
- The addition of adrenaline (0.00198%) to bilateral maxillary nerve blocks significantly reduced intraoperative hemorrhage in dogs undergoing sharp staphylectomy (median reduction: 77.1%).
- Normalized hemorrhage (g/kg) and total hemorrhage (g) were significantly lower in the adrenaline group (p = .021 and p = .013, respectively).
- Surgeon-assessed hemorrhage scores were also significantly lower in the adrenaline group (median 2 vs. 3; p = .029), indicating improved surgical visibility.
- No adverse effects (e.g. tachycardia, arrhythmia, or hypertension) were observed with adrenaline administration.
- A standardized intraoral approach to the maxillary nerve block was used with 0.5 mL per side regardless of dog size.
- Breed effect observed: English Bulldogs had higher normalized hemorrhage, possibly due to anatomical variation or underdosing relative to size.
- Adrenaline may also prolong local anesthetic action and reduce blood aspiration risks, though this was not directly measured.
- The study supports the routine inclusion of adrenaline in maxillary nerve blocks for staphylectomy in BOAS patients to improve surgical field and reduce bleeding.

In Silveira 2022 et al., on GTO in canine THR, which scenario was considered a suitable indication for performing a greater trochanter osteotomy?
🔍 Key Findings
- GTO enabled successful cementless THR in dogs with severe medialization of the greater trochanter or chronic craniodorsal hip luxation.
- All 5 hips had acceptable long-term outcomes (median follow-up: 48 months) with full function and no persistent complications.
- Only one major complication occurred—a luxation unrelated to the GTO and successfully corrected with cup revision.
- GTO facilitated femoral canal access and gluteal preservation, reducing risk of iatrogenic injury during broaching.
- All GTOs healed radiographically (4 by 6 weeks, 1 by 12 weeks), with no cases of nonunion or implant migration.
- No complications related to GTO or PTBW fixation (pins + tension band) were observed in any dog.
- Surgical planning included templating both THR and GTO to ensure ideal alignment and reduce fracture risk.
- GTO may be especially valuable in luxoid hip dysplasia phenotypes or chronically fixed luxations.

In Welsh 2025 et al., on orthogonal plating, what was observed in all constructs?
🔍 Key Findings
- Compared unilateral plating (UP) vs orthogonal plating (OP) with 2.0, 2.4, and 3.0 mm plates (OP2.0, OP2.4, OP3.0).
- Model: acetal homopolymer (Delrin) rod with 29 mm fixed fracture gap, loaded axially (4–196 N, 90,000 cycles).
- OP constructs had 2.5–4.1x higher strength and 3.0–4.2x higher stiffness than UP constructs (p < .0002).
- UP had 3.5–4.1x higher gap strain than OP groups (p < .0075).
- All OP groups exceeded 1000 N max load before failure (vs 424 N for UP).
- Greater implant size in OP groups further increased performance.
- All constructs survived fatigue loading; 3.5 mm plates showed deformation, especially UP; OP plates remained intact.

In Parlier 2024 et al., on insufflation effects on portal pressure in dogs, what was the average portal pressure increase per mmHg insufflation pressure?
🔍 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 Burkhardt 2024 et al., on coagulation testing in liver lobectomy, which liver tumor type was significantly associated with both PT and aPTT prolongation?
🔍 Key Findings
- 20.6% of dogs had a preoperative prolongation in PT or aPTT, but only 5.6% had both prolonged.
- Hemangiosarcoma was the only tumor type significantly associated with both PT and aPTT prolongation (37.5% of hemangiosarcoma cases, p < .001).
- Dogs with both PT and aPTT prolongations were 6.5× more likely to have emergency surgery (p < .001) and 2.5× more likely to have hemoabdomen (p = .0022).
- 60% of dogs with both PT and aPTT prolongation required blood transfusion (p < .001).
- Only 1.9% of all dogs had both PT and aPTT prolonged by >25%, suggesting limited clinical utility of routine PT/aPTT testing.
- Platelet count <50,000/μL was rare (1.5%) and not associated with PT/aPTT changes or transfusions.
- Routine PT/aPTT testing offers low diagnostic yield in elective liver lobectomy cases.
- Authors recommend case-by-case PT/aPTT screening, especially when hemangiosarcoma or bleeding tendencies are suspected.

In Rocheleau 2025 et al., on infected total hip replacements, which of the following best describes the culture outcomes for the non-curative intent (NCI) group?
🔍 Key Findings
Study Design: Case series of 8 dogs with confirmed or suspected PJI after total hip replacement (THR)
Dogs were categorized into:
- Curative intent (CI) group (n=5): short-duration infections, implant retention attempted
- Non-curative intent (NCI) group (n=3): chronic infections, implants scheduled for removal or revision
Success Rate: 7 of 8 dogs had infection resolution, including 4 of 5 in the CI group
Sampling sensitivity:
- Arthroscopic culture success was 80% in the CI group but only 33% in the NCI group
- All explanted implants from NCI group yielded positive cultures
Common isolates: Staphylococcus pseudointermedius (including MRSP), S. epidermidis, Stenotrophomonas maltophilia, and E. coli
Ancillary treatments included:
- Partial synovectomy, high-volume lavage (5–10 L), biofilm-depleting lavage, and/or amikacin-impregnated calcium sulfate beads
Mean follow-up: >1 year (mean 812 days); no signs of recurrence in successfully treated cases
Conclusions: Arthroscopic management of THR infections is feasible and effective in appropriately selected dogs. Success aligns with human literature when infection type is favorable (Type 1, 3, 4). Sensitivity of arthroscopic culture is higher in early/acute infections.

In Sadowitz 2023 et al., on screw angle & speed, which factor most strongly contributed to increased TCF risk?
🔍 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 Cherzan 2023 et al., on subcutaneous mast cell tumors, what was the median disease-free interval (DFI) for dogs with lymph node metastasis from subcutaneous mast cell tumors?
🔍 Key Findings
- Local recurrence occurred in 17.8% of dogs, and was associated with significantly decreased survival (551 vs 1722 days, p = .0038).
- Lymph node metastasis occurred in 26.7% of dogs and was significantly associated with shorter disease-free interval (194 vs not reached, p = .0012) and lower survival (551 vs 1722 days, p = .043).
- Mitotic index >7 was significantly associated with higher recurrence (80% vs 22.5%, p = .02), shorter DFI (139 vs not reached days, p < .001), and shorter survival (247 vs 1722 days, p = .05).
- Infiltrative growth pattern was associated with shorter DFI (268 vs 1864 days, p = .011), but not with survival or recurrence.
- Incomplete margins (≤1 mm) were not significantly associated with recurrence (p = .085), but did correlate with shorter DFI (p = .043).
- Chemotherapy or radiation therapy was associated with shorter DFI and survival, likely due to selection bias for more aggressive disease.
- Tumor size >3 cm was associated with decreased survival (p = .031), but not with recurrence or DFI.
- Multinucleation and necrosis were not associated with prognosis outcomes.
