In Dalton 2023 et al., on acetabular fracture repair, what was a reported potential benefit of the minimally invasive approach compared to traditional open techniques?
🔍 Key Findings
- Minimally invasive repair of acetabular fractures using precontoured plates on 3D-printed models is feasible and technically reproducible in dogs.
- All cadavers had fracture gaps <2 mm and step defects <1 mm, indicating accurate reduction.
- Sciatic nerve injury was minimal or absent in all cases, supporting potential neuroprotection from indirect approaches.
- Pelvic angulation was maintained <5°, confirming preservation of alignment post-reduction.
- Surgical time averaged ~46 minutes in cadavers for both approaches and repair.
- Clinical case showed good radiographic healing by 8 weeks and full union by 3 months, with early weight-bearing post-op.
- Use of locking screws improved reduction fidelity, particularly across a broad plate span.
- 3D printing accelerated surgical planning, though its necessity remains debated due to the availability and cost concerns.

In Dobberstein 2024 et al., on liver biopsy forceps, how did the number of portal triads compare between forceps sizes?
🔍 Key Findings Summary
- Subjects: 12 healthy colony cats, 68 total liver samples collected via laparoscopy
- Biopsy instruments: 3 mm vs 5 mm Storz Blakesley cup forceps
- Techniques: Twist (T), Pull (P), Twist + Pull (TP)
- Results:
- 5 mm forceps yielded significantly more hepatic lobules (mean 12.4 vs 4.9), portal triads (29.6 vs 19.0), weight, and histologic area (p < .01)
- T and P techniques yielded more portal triads and lobules than TP (p = .003 and p = .015)
- TP technique resulted in greater tissue crush vs T (p = .01)
- Good diagnostic agreement between 3 mm and 5 mm samples only with TP (κ = 0.75)
- All samples were of sufficient diagnostic quality, despite size or technique
- Clinical implication: Both 3 mm and 5 mm forceps are viable; further studies are needed to confirm diagnostic accuracy of 3 mm samples

In Hertel 2025 et al., on portal venotomy for insulinoma, what was the duration of portal vein occlusion tolerated during surgery?
🔍 Key Findings
- Portal venotomy enabled successful en bloc resection of a pancreatic insulinoma and associated thrombus in the portal vein, a novel approach in veterinary literature.
- Temporary portal vein occlusion (15 min) was well tolerated, causing only transient small intestinal congestion without lasting hemodynamic compromise.
- No intraoperative hemorrhage occurred following vascular isolation and venotomy repair with 5–0 polypropylene in a simple continuous pattern.
- Postoperative complications were minimal, with only moderate pancreatitis managed medically and no portal hypertension observed on follow-up imaging.
- Histopathology confirmed insulinoma, with no initial metastasis; CT at 6 months revealed hepatic and peritoneal metastases but no local recurrence at the venotomy site.
- Portal vein luminal stenosis occurred post-repair but was clinically insignificant.
- Advanced CT imaging and 3D printed modeling significantly enhanced surgical planning and anatomical assessment.
- Surgical excision achieved good short-term outcomes, and the dog was alive and euglycemic one year later despite metastatic disease.

In Schmutterer 2024 et al., what was the trend in mean pressure on the medial meniscus across all angles tested?
🔍 Key Findings Summary
- Biomechanical study on 14 hindlimbs from Retrievers (cadaveric)
- Three stifle flexion angles tested: 125°, 135°, and 145°
- Contact Force Ratio (CFR) was significantly higher at 125° and 135° than at 145° (p < 0.001)
- Center of force shifted caudally with increasing flexion — especially in medial meniscus
- Lateral meniscus peak pressure was significantly higher at 125° than 145° (p = 0.049)
- Mean pressures on lateral meniscus decreased with extension, while medial meniscus pressure remained constant
- Relevance: Helps interpret meniscal load in early cruciate disease and in surgical modeling

In Low 2024 et al., how did complication presence affect long-term functional outcome?
🔍 Key Findings Summary
- 47 dogs (57 elbows) underwent TCS placement for HIF
- Overall complication rate = 17.5%
- Minor: seromas (7 elbows)
- Major: septic arthritis (3 elbows) — all resolved with antibiotics
- No screw failures, medial epicondylar fractures, or catastrophic outcomes noted
- Long-term follow-up in 41 dogs (50 elbows):
- 90% full function, 10% acceptable function
- Mean follow-up = ~2.5 years
- Increased age was significantly protective (p = 0.0051; OR = 0.61)
- TCS placement method (freehand, guide, aiming device) significantly impacted screw angulation but not complication rate
- Outcome not affected by presence of complications

In Larose 2024 et al., on laparoscopic liver biopsies in dogs, what biopsy surface area was associated with a 98% probability of obtaining ≥11 portal triads?
🔍 Key Findings
- Histologic agreement between 3 mm and 5 mm biopsies was 90%, with a Gwet's AC1 of 0.81 (p < .0001).
- 5 mm biopsies yielded significantly more portal triads and lobules than 3 mm samples (p = .0003 and p < .0001).
- Crush artifacts were significantly higher in 3 mm samples (p = .035), though fragmentation scores were similar (p = .935).
- Both forceps produced adequate samples for histopathology, copper quantification, and bacterial culture.
- No hemorrhage requiring intervention occurred, and both sizes were deemed safe and minimally invasive.
- Surface area ≥40 mm² strongly predicted ≥11 portal triads, a desirable threshold for reliable histopathology.
- Use of 3 mm instruments was easier in small dogs (<12 kg), but more challenging in larger dogs due to shaft length.
- Clinical diagnoses were unaffected by forceps size, even in the one discordant histologic pair.

In Vodnarek 2024 et al., on intraobserver performance, which observer achieved **excellent reliability** for both methods?
🔍 Key Findings
- Study population: 36 brachycephalic dogs (20 French bulldogs, 16 pugs).
- Objective: Compare intra- and interobserver reliability for fluoroscopic measurement of nasopharyngeal collapse using two methods:
- Functional method
- Anatomically adjusted method
- Key measurements: Minimum (LMin), maximum (LMax) dorsoventral height, and dynamic change ratio (ΔL).
- Outcomes:
- Intraobserver agreement for ΔL was higher with the functional method (ICC 0.751 vs. 0.576).
- Observer 1 (radiologist) showed excellent repeatability (>0.9 ICC).
- Agreement for grading collapse was only moderate (κ ~0.49–0.53), worse than ΔL-based agreement.
- ΔL ≥ 0.5 to <1 = partial collapse; ΔL = 1 = complete collapse.

🔍 Key Findings
- Ventral Compression Index (VCI) ≥0.16 (extension) or ≥0.2 (flexion) was diagnostic for AAI with 100% sensitivity and >94% specificity
- VCI had the highest diagnostic accuracy among all measured variables (AUC > 0.99)
- C1-C2 overlap ≤2.7 mm (extension) or ≤1.8 mm (flexion) also diagnostic for AAI (sensitivity 84–96%, specificity 81–90%)
- C1-C2 angle ≥176.9° (extension) or ≥187.4° (flexion) had high sensitivity and specificity (~95%)
- Basion-dens interval ≥5.9 mm (extension) or ≥3.0 mm (flexion) provided moderate diagnostic accuracy
- Cranial translation ratio (CTR) ≥0.18 classified dogs as potentially unstable (sensitivity 90%, specificity 78%)
- VCI ≥0.23 reliably differentiated AAI from potentially unstable cases (sensitivity 94%, specificity 94%)
- DALR ≤0.24 had high specificity (100%) but low sensitivity for AAI diagnosis

In Lampart 2023 et al., on manual laxity testing, how did subjective estimates of cranial tibial translation (CTT) compare with objective values?
🔍 Key Findings
- Cranial drawer (CD), tibial compression (TCT), and tibial pivot compression test (TPCT) showed 100% sensitivity and specificity in differentiating intact from CCL-deficient stifles in this ex vivo model.
- TPCT elicited the highest cranial tibial translation (CTT) and internal tibial rotation, though differences in rotation did not reach statistical significance.
- Inter- and intraobserver agreement for CTT was excellent across all tests (ICC >0.9).
- Rotation and force application had greater variability, particularly with less experienced observers and during CD.
- Forces applied during CD were significantly higher in intact limbs and correlated with observer experience.
- Subjective CTT estimates strongly correlated with objective kinematic measurements (r = 0.895), with a median absolute error of 1.31 mm.
- TPCT may be particularly useful for assessing rotational instability, mimicking the pivot-shift test used in human ACL exams.
- Study supports development of a grading system for manual laxity testing, especially in acute CCLR cases.
