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 Vodnarek 2024 et al., on method comparison, which statement is true regarding the **anatomically adjusted method**?
🔍 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.

In Moreira 2024 et al., on predictive equations for TPA correction, which technique demonstrated the **highest TLA shift** after cranial cortical alignment?
🔍 Key Findings
- A linear relationship was observed between wedge angle and tibial plateau angle (TPA) correction across all four CCWO techniques.
- All techniques produced predictable TPA corrections using linear regression-derived equations, allowing wedge angle extrapolation to achieve a target postoperative TPA of 5°.
- TLA shift (tibial long axis) increased with wedge angle and influenced final TPA; greatest in Frederick & Cross method.
- Tibial shortening (mTL%) varied by technique, being most severe (up to 40.9%) in traditional Slocum & Devine CCWO and least in newer techniques (7.5–12%).
- The Oxley mCCWO technique showed lower TLA shift compared to the Frederick & Cross and Christ techniques, though similar to Slocum & Devine; tibial shortening was more pronounced than other modified techniques at wedge angles ≤40°.
- Techniques varied in craniocaudal translation and wedge apex positioning, influencing planning accuracy and mechanical axis alignment.
- The corrective wedge angle equations reliably predicted TPA within 4–6° across varied tibial conformations.
- The study supports equation-based planning over static TPA–5° subtraction to reduce risk of under- or over-correction.

In Scheuermann 2023 et al., on MIPO with 3D-printed bone models, what was the tradeoff of using the FRS compared with IMP reduction?
🔍 Key Findings
- Precontoured plates based on 3D-printed femurs produced accurate femoral alignment (median deviations <3 mm or <3° in all planes).
- Both fracture reduction system (FRS) and intramedullary pin (IMP) methods achieved near-anatomic alignment in cadaveric femoral fractures.
- FRS required fewer fluoroscopic images (median 7 vs. 26, P = .001), but longer surgical time (median 43 vs. 29 min, P = .011).
- Sagittal plane alignment: FRS led to mild increased recurvatum (median 2.9°), but still within near-anatomic limits (<5°).
- Axial alignment: Both groups achieved near-anatomic torsion (<10°), though one IMP case had acceptable (not near-anatomic) alignment.
- Custom drill guides and FRS improved fluoroscopy efficiency but were cumbersome and time-consuming to use. Authors do not recommend current prototype for clinical use.
- Clinical significance: 3D printed models allow accurate precontouring, reducing intra-op plate adjustment; custom guides may reduce radiation exposure for the surgical team.

In Fidelis 2025 et al., on suture eyelet geometry, what was the **most common failure location** for sutures in anchors with embedded eyelets?
🔍 Key Findings
- Raised eyelets caused more suture mid-section failures than embedded eyelets, suggesting wear or cutting against the anchor.
- No significant effect of cyclic loading on failure load (Fmax) was found for any anchor group.
- Anika anchor showed the least reduction in suture strength relative to the reference (eyebolt screw), indicating a favorable design.
- All sutures failed via suture breakage, not anchor pullout, indicating suture fatigue was the primary failure mode.
- Sutures in raised eyelets more often failed at the mid-section, while those in embedded eyelets failed at the knot.
- IMEX and Jorvet anchors showed significantly reduced Fmax compared to eyebolt screws.
- Loading direction and anchor design likely affect wear and ultimate failure, particularly in dynamic in vivo conditions.
- Future designs should aim for embedded, smooth eyelets that can accommodate larger suture sizes without increasing wear.

In Nash 2024 et al., on esophageal pH monitoring, what was the defined upper reference limit for distal GER events per hour in healthy nonbrachycephalic dogs?
🔍 Key Findings
- Esophageal pH-monitoring was well tolerated in all 35 nonbrachycephalic dogs, with no major adverse events reported.
- Distal GER occurred in 80% of dogs, but events were typically brief and non-productive; proximal GER occurred in only 39%.
- Upper reference limits for GER were 2.4 events/hour (distal) and 0.4 events/hour (proximal).
- Cumulative acid exposure was minimal: upper limits were 2.3% (distal) and 0% (proximal).
- Comparison with brachycephalic dogs shows significantly higher GER frequency and duration, validating the diagnostic utility of pH monitoring.
- Transnasal probe placement under light anesthesia was safe and less morbid compared to percutaneous or conscious techniques.
- No expelled or productive regurgitation occurred, despite some GER events, indicating efficient esophageal clearance in healthy dogs.
- Diet and fasting duration may affect GER, but these were not controlled variables in this study.

In Haine 2022 et al., on outcomes in canine limb tumors, what proportion of dogs developed local recurrence or metastasis postoperatively?
🔍 Key Findings
- Fewer R1 margins (tumor on ink) were achieved in mast cell tumors (MCTs) when using 6–10 mm lateral margins versus 0–5 mm (7% vs. 55%; _P_ = .049).
- For soft tissue sarcomas (STSs), no benefit was seen in margin completeness between 0–5 mm vs. 6–10 mm lateral margins (41% vs. 43% R1).
- Overall R1 rates were 26% for MCTs and 42% for STSs following PNE.
- R scheme (“tumor on ink” = R1) had better interobserver agreement (83%) compared to ≤1 mm margin criteria (68% agreement).
- Complication rate was moderate (26%), but no surgeries required revision.
- Local recurrence/metastasis occurred in 14% of dogs, with 60% of those having R1 margins.
- Adjunctive therapy was considered clinically indicated in 46% of 0–5 mm margin cases vs. 24% of 6–10 mm cases.
- Histologic grade and tumor size were not predictive of margin completeness.
