In Quitzan 2022 et al., on staple line configuration, which FEESA variation did *not* significantly increase ILP compared to 2V/2T?
🔍 Key Findings
- All FEESA configurations leaked at lower pressures than intact segments, confirming reduced integrity vs. native tissue.
- FEESA with 3-row transverse staples (3V/3T or 2V/3T) had significantly higher leak pressures than 2-row configurations.
- 3V/3T configuration had the highest ILP (69.88 ± 21.23 mmHg) among all groups, significantly greater than 2V/2T and 3V/2T (P < .001).
- Leakage consistently occurred at the transverse staple line (not vertical), regardless of configuration.
- No significant difference in maximum intraluminal pressure (MIP) between FEESA groups.
- All FEESA constructs withstood intraluminal pressures >25 mmHg, exceeding normal physiological jejunal pressure in dogs.
- No leaks occurred from the vertical staple line, highlighting it as a more robust closure site.
- Third staple row in transverse line may be a viable alternative to suture oversew, pending further clinical evaluation.

In Hawker 2025 et al., on locking head inserts, where was peak strain localized during testing?
🔍 Key Findings
- Adding Locking Head Inserts (LHI) to a 3.5-mm LCP had no effect on plate strain, stiffness, or deformation in an open fracture gap model.
- Peak strain consistently occurred at the Combi-hole over the fracture gap, with values up to ~1837 µε.
- No significant difference in strain was found across configurations with 0, 3, or 9 LHI (p = 0.847).
- Construct stiffness and compressive displacement also remained unchanged regardless of LHI count (p = 0.311 and 0.069 respectively).
- Study contradicted the hypothesis that LHI would reduce strain and increase stiffness under biologic loading.
- Combi-hole design may limit the efficacy of LHI, as LHI only fill the locking portion, not the compression side where strain peaks.
- Implant fatigue risk remains highest over unfilled screw holes, especially over fracture sites—confirming previous failure patterns.
- Surgeons should consider alternative methods to reduce strain when facing high implant load scenarios.

In Lu 2025 et al., on SOP constructs, which mechanical axis showed greater bending stiffness regardless of tee usage?
🔍 Key Findings
- Bending tees significantly increased mediolateral bending stiffness, but not craniocaudal stiffness, in plate-bone constructs.
- Mean mediolateral stiffness was 43.2 N/mm with tees vs. 41.1 N/mm without (p = 0.0042), though the absolute difference was small.
- No significant differences were found in craniocaudal bending stiffness between constructs with or without tees (p = 0.89).
- Plastic deformation occurred in all constructs; no screw pull-out or implant breakage was observed.
- SOP nodes may resist compressive but not tensile deformation, suggesting variable mechanical contributions depending on loading direction.
- Craniocaudal bending had greater stiffness than mediolateral due to higher area moment of inertia along the node diameter.
- Clinical relevance of added stiffness from tees remains unclear, warranting further in vivo and cyclic testing.
- This was the first study to directly test SOP constructs with/without tees over a fracture gap in multiple planes.

In Banks 2024 et al., on CCWO planning accuracy, what was the **mean planned tibial plateau angle (TPA)** using Oxley’s modified method?
🔍 Key Findings
- Oxley's modified CCWO did not achieve the target TPA of 5° in most cases, even with planning.
- Mean planned TPA was 7.6°, higher than target, and consistent across dog sizes.
- Postoperative TPAs were significantly higher in small dogs (median 7°) than in large dogs (median 4.5°).
- Distalization >7.5 mm of the osteotomy from the patellar tendon led to increased under-correction of TPA.
- Only dogs with preoperative TPA >35° achieved post-planning TPAs close to the 5° target.
- Postoperative osteotomy positions were generally more distal than recommended (8.6 mm median).
- Virtual plate fit was appropriate for all dogs at 5 mm or 7.5 mm positions, suggesting no need for excessive distalization.
- Excessive correction leading to negative TPAs occurred in some cases, risking caudal cruciate ligament strain.

In Williams 2024 et al., on adrenaline use in maxillary nerve blocks, what was the standard volume of local anesthetic injected per side during the block?
🔍 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 Katz 2022 et al., on meniscal flounce sign, what was the diagnostic accuracy of the sign for indicating an intact or torn meniscus during stifle arthroscopy?
🔍 Key Findings
- A positive meniscal flounce sign was associated with normal menisci in 95.5% of cases, demonstrating strong predictive value.
- Absence of the meniscal flounce sign was associated with meniscal tears in 92.7% of cases.
- Overall diagnostic accuracy of the flounce sign was 94.6%, with 96.6% sensitivity and 90.5% specificity.
- Most tears in flounce-negative stifles were bucket-handle tears (73.8%), while radial tears were present in some flounce-positive stifles.
- Radial tears did not consistently eliminate the flounce sign, suggesting they may not disrupt meniscal fiber tension sufficiently.
- All procedures were arthroscopically performed, with probing and visualization of the medial meniscus' caudal pole.
- Flounce sign should complement, not replace, probing—especially as some tear types (e.g., radial) may not abolish the sign.
- Limb positioning and joint distraction may affect flounce visibility, introducing minor observer variability.

In Rocheleau 2023 et al., on shoulder stabilization, what was the overall targeting accuracy of the intra-articular aiming device (IAD) during shoulder stabilization?
🔍 Key Findings
- Arthroscopically assisted stabilization with an IAD was feasible in cadaveric canine shoulders using both bone anchor and suture-toggle techniques.
- Suture-toggle repair was successfully performed in all specimens, while bone anchors could not be deployed in 3/10 shoulders, indicating lower feasibility.
- Median surgical time was shorter for the suture-toggle group (25.5 min) compared to the anchor group (37.3 min).
- Postoperative abduction angles returned to baseline in the anchor group, while the suture-toggle group had slightly reduced angles, suggesting possible overtightening.
- Violation of the articular surface occurred in 2 anchor specimens and 1 suture-toggle specimen, but none were considered likely to be clinically significant.
- Overall targeting accuracy using the IAD was 88%, supporting its utility in guiding tunnel/anchor placement.
- CT measurements showed acceptable bone stock and insertion angles, but anchor insertion angles were lower than optimal for mechanical pullout strength.
- Suture-toggle technique was considered simpler and more consistent, with fewer complications and faster execution than anchor placement.

In Guevara 2024 et al., on implant placement accuracy, which vertebra had the lowest odds of acceptable pin placement?
🔍 Key Findings:
- Sample: 24 canine cadavers, 477 total pins across 240 vertebrae.
- Technique Comparison: 3D printed guides (3DPG) vs freehand (FH).
- Acceptable Placement Rates: 3DPG = 87.5%, FH = 69.8% (p < .0001).
- Odds Ratio for FH: 0.28 (95% CI 0.16–0.47), significantly less likely to yield acceptable placement.
- Worst Accuracy Locations: T10 (OR 0.10), T11 (OR 0.35).
- Surgeon Impact: Surgeon 2 outperformed others (OR 9.61, p = .001).
- Modified Zdichavsky Classification used to score implant accuracy (Grades I–IIIb).
- Primary Benefit of 3DPG: Increased safety and precision, regardless of surgeon experience.

In Galliano 2022 et al., on vascular access ports, what was the reported functionality rate of ports placed in the femoral/external iliac vein (fSVAP)?
🔍 Key Findings
- SVAPs placed in axillary (aSVAP) or femoral/external iliac veins (fSVAP) during limb amputation remained functional in 92.3% and 100% of cases, respectively.
- Complication rates were lower in aSVAP (23.1%) and fSVAP (0%) compared to jSVAP (47.4%), although not statistically significant (P = .12).
- No catastrophic complications occurred with aSVAP or fSVAP; 2 deaths occurred with jSVAP due to port-related issues.
- Infection-related port removal was needed in 1 aSVAP (7.7%) and 2 jSVAPs (10.5%) — no removals were required in fSVAPs.
- Tip placement of the catheter (e.g., right atrium vs. vena cava) did not correlate with complications (P = .66).
- Shorter surgical time likely with aSVAP/fSVAP as they use the same surgical field as the limb amputation.
- Survival time median was similar across groups (jSVAP: 177 days, aSVAP: 125 days, fSVAP: 122 days).
- SVAP implantation during limb amputation offers a practical and safe alternative to separate jugular placement.
