Quiz Question
In Alvarez-Sanchez 2023 et al., on SLN mapping in canine MCT, how often did the anatomic lymph node (ALN) match the SLN identified by ICTL?
🔍 Key Findings
- Combined ICTL and NIRF detected the same SLN in 80% of cases; each method alone missed sentinel lymph nodes in some dogs.
- ICLT failed in 5% of dogs, while NIRF failed in 20%; combined use resulted in only 5% failure in SLN detection.
- Metastatic lymph nodes were detected in 95% of dogs, despite most tumors being low or intermediate grade (95%).
- 27 of 41 nodes (65.8%) were histologically metastatic (HN2 or HN3), many of which would have been missed using ALN alone.
- ALN matched the SLN in only 45% of cases with ICTL and 30% with NIRF, supporting the need for SLN mapping.
- ICLT and NIRF were complementary, often identifying different SLN, with some only fluorescent or enhanced in one modality.
- Subcutaneous MCT had higher metastatic rates (7/8 dogs) than previously reported, challenging older assumptions about benign behavior.
- Removing both ALN and SLN (from both methods) improved detection of metastasis to 85–95%, reducing risk of understaging.

In Sisk 2024 et al., what conclusion did the authors draw regarding reamed versus unreamed IMN in dogs?
🔍 Key Findings Summary
- IMN provides relative stability, resists bending/torsion due to central axis alignment
- Larger diameter nails = exponentially greater stiffness (∝ D⁴)
- Trade-off: Larger interlocking holes weaken fatigue strength of the nail
- Reaming increases contact/stability but has pros/cons:
- Improves outcomes in closed fractures
- May reduce endosteal blood flow in thin-walled bones (e.g., cats)
- Design advances:
- Angle-stable IMN reduce rotational slack
- Expandable nails simplify insertion but may compromise removal or compressive load resistance
- Precontoured nails match bone curvature but lack consistent clinical superiority
- Material debates continue (e.g., titanium vs. stainless steel vs. magnesium)

In Scharpf 2024 et al., what type of analysis was used to assess limb loading recovery over time?
🔍 Key Findings Summary
- Subtotal coronoidectomy improved vertical and propulsive forces, but braking forces remained subnormal at 26 weeks.
- No significant benefit was seen from ACP vs placebo at any timepoint across all force parameters or lameness scores.
- Force plate analysis was more sensitive than visual lameness scoring.
- Braking force (%FY+) was best at detecting persistent lameness, and SI < 0.9 persisted in most dogs at 26 weeks.
- Outcome less favorable than historically reported — challenges status of subtotal coronoidectomy as “gold standard” for MCD.

In Marturello 2023 et al., on 3D-printed humeral models, which factor had the **greatest influence** on model accuracy?
🔍 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 Lee 2022 et al., on TPLO accuracy, what was a noted limitation affecting the generalizability of the study?
🔍 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.

In Bower 2025 et al., on radial diaphyseal exposure, which statement best describes the comparison between craniomedial and craniolateral approaches?
🔍 Key Findings
- Craniomedial and craniolateral approaches provided comparable exposure of the feline radial diaphysis (p > .05).
- Mean exposed surface area was slightly greater with the craniolateral approach, both including and excluding the supinator muscle, but differences were not significant.
- Elevation of the supinator muscle increased exposure for both approaches.
- Cadaver weight and limb side did not significantly affect exposure area.
- The craniolateral approach allows easier patient positioning in lateral recumbency without traction or an assistant.
- Craniolateral access facilitates dual bone fixation (radius and ulna) through a single approach.
- The craniomedial approach carries greater risk to median and radial nerves during muscle elevation.
- Findings validate the craniolateral approach as a practical alternative for feline antebrachial fracture repair.

In Buote 2023 et al., on laparoscopic sleeve gastrectomy in cats, what was the mean percentage of stomach weight resected in the cadaveric LVSG procedures?
🔍 Key Findings
- LVSG was feasible in 9/10 feline cadavers and both live cats, with no intra- or postoperative complications in live cases.
- Two cadavers developed suspected stenosis due to staple lines too close to the lesser curvature; avoided with orogastric tube placement in later cases.
- No evidence of gastric leakage in any cadavers (8/10 tested) or live patients after methylene blue leak tests.
- Mean surgical time was ~110 min cadavers / 115 min live, and 27.6% of stomach mass was resected.
- Both live cats recovered uneventfully, lost 21–24% body weight over 3 months, and had no GI complications at 6-month follow-up.
- Orogastric tube and tension on the greater curvature were critical to avoid staple line misplacement or stenosis.
- No oversew of the staple line was needed, and unreinforced staples showed no leakage in live patients.
- Future studies needed to assess metabolic outcomes and ideal staple sizing and closure techniques.

In Nagahiro 2023 et al., on quadriceps-femoral mismatch, which variables were significantly associated with a decreased QML/FL in the final regression model?
🔍 Key Findings
- Quadriceps muscle length/femoral length ratio (QML/FL) was significantly lower in dogs with grade IV MPL than grades I–III (p ≤ .002).
- Shortened QML was associated with increased femoral torsion angle (FTA) and increased aLDFA, indicating correlation with femoral deformity.
- QML/FL increased with age, possibly due to muscular development or reduced deformity in older dogs (p = .004).
- Grade IV MPL dogs had QML/FL < 0.87, the lower normal limit based on healthy beagles, suggesting clinically significant muscle shortening.
- PLL/PL ratio (used to diagnose patella alta) was not associated with QML/FL or MPL severity in small breeds.
- QML/FL can help preoperatively identify candidates for femoral shortening ostectomy, improving femoropatellar alignment.
- Multivariate regression model confirmed QML/FL is independently influenced by age, FTA, and aLDFA (R² = 0.45).
- CT-based 3D measurements enabled objective, noninvasive quantification of femoral and muscle alignment parameters.

In Peng 2025 et al., on topical amikacin gel, what maximum topical dose per kg was administered?
🔍 Key Findings
Objective: Determine if topical 45 mg/mL amikacin in CMC gel leads to systemic absorption in dogs with wounds.
Dogs enrolled: 11 client-owned dogs, with 31 applications of the gel.
Serum findings:
- Only 5 of 153 samples were above the 2.5 µg/mL quantification limit
- All values remained <5 µg/mL, the presumed toxicity threshold
- No correlation was found between dose-related parameters (mg, mg/kg, mg/cm²) and serum amikacin levels
Peak concentrations were observed at ~2 hours post-application, declining rapidly thereafter
No nephrotoxicity observed, and most values were below detection
Conclusion: Topical amikacin gel appears safe at doses up to 24.9 mg/kg, with minimal systemic absorption
