- Diagnostic Metrics (Reading 2):
- Sensitivity: 1.00 (Observers 1 & 2), 0.93 (Observer 3)
- Specificity: 0.78–0.91
- Positive Likelihood Ratio: Up to 10.71
- Negative Likelihood Ratio: As low as 0.08
- Accuracy: 90%+ for all in Reading 2
- Observer Effect: Significant improvement between first and second reading for less experienced observers (p < 0.05); learning curve evident.
- Meniscal lesions found:
- 9/12 in suspected late meniscal injury cases
- 19/40 in newly diagnosed CCL cases
- Most common = bucket handle tears
- Conclusion: Multidetector CTA is a clinically useful, non-invasive tool for identifying medial meniscal lesions in dogs with CCL disease.

In Brisimi 2022 et al., on tracheal anastomosis tension, which group demonstrated significantly higher force to failure?
🔍 Key Findings
- Tracheal anastomoses in immature dogs failed at significantly lower distraction forces (44.91 ± 59.03 N) than in adults (149.31 ± 45.36 N; _P_ = .007).
- Immature tracheae tolerated significantly more elongation before failure (39.75 ± 5.45%) than adult tracheae (30.57 ± 7.19%; _P_ = .0012).
- All constructs failed by suture tearing through the annular ligament, primarily near the dorsal tracheal ring.
- Overlapping of tracheal ends was seen in 50% of specimens across both age groups, suggesting limitations in tissue apposition with the chosen technique.
- Simple continuous pattern using 2-0 polypropylene was used; this pattern provides superior tensile strength compared to simple interrupted, but apposition may be suboptimal.
- Tracheal elasticity in immature dogs may allow longer resections, but the lower tensile strength necessitates reinforcement.
- Annular ligament-cartilage technique with 4-mm suture spacing showed variable results; smaller bites and nylon suture may improve outcomes.
- Ex vivo setup using frozen-thawed tracheae is a limitation, but prior studies support comparability with fresh tissue.

In Barrett 2026 et al., on scapula plating biomechanics, how did displacement compare between constructs?
🔍 Key Findings
- Double plate fixation significantly increased construct stiffness (563.7 vs 392.8 N/mm; p < .0001), supporting superior biomechanical stability
- Displacement was significantly reduced with double plating (−0.48 mm vs −0.81 mm; p < .0001), indicating improved resistance to cyclic loading
- No difference in primary plate strain between single and double constructs, suggesting load-sharing did not reduce plate stress
- Caudolateral placement of the second plate enhances biomechanical advantage by increasing moment arm and resisting tensile forces
- Cyclic loading model (7200 cycles) simulated 1 hour of walking, making findings clinically relevant to early postoperative activity
- Strain across fracture gap was lower in double plate constructs (~4.3% vs ~6.9%), supporting improved conditions for fracture healing
- No construct failures occurred, but actuator slippage occurred only in double plate group, highlighting potential testing/artifact considerations
- Clinical implication: double plating may allow earlier weightbearing and reduce need for external coaptation, improving recovery outcomes

In Thompson 2024 et al., on cyanoacrylate enterotomy sealants, what was the most common leak location in the cyanoacrylate-only (CE) group?
🔍 Key Findings
- Highest initial leak pressure (ILP) observed in the handsewn + cyanoacrylate (HS + CE) group: 83.3 ± 4.6 mmHg (p < .001 vs. others).
- Lowest ILP: cyanoacrylate-only group (CE): 18.6 ± 3.5 mmHg.
- No significant MIP difference between handsewn (HSE) and HS + CE groups (p = .19); CE had significantly lower MIP (22.7 mmHg).
- Leak location:
- HSE: 60% from suture holes
- CE: 100% from incisional line
- HS + CE: 60% from incisional line, 40% from suture holes
- Authors conclude cyanoacrylate augmentation significantly increases ILP and could reduce enterotomy leakage risk.

In Meltzer 2022 et al., on femoral implant selection, what was the most common major complication reported?
🔍 Key Findings
- Hybrid implants were used in older, heavier dogs with lower canal flare index (CFI) compared to cementless types.
- CFI <1.8 was associated with higher risk of femoral fracture or stem subsidence with cementless implants.
- Total complication rate was 14%, with catastrophic complications in only 1.5%—lower than reported in other studies.
- No significant difference in complication rates across implant types (BFX, BFX-C, hybrid).
- Femur fractures were rare (2.9%), lower than in prior studies, and successfully managed with cerclage/plate fixation.
- Coxofemoral luxation was the most common complication (8 cases); all occurred within 62 days post-op, mostly resolved with revision.
- Collared BFX stems did not significantly reduce complications, though they may limit stem subsidence.
- An implant selection algorithm was proposed, using age ≥7 years, weight ≥45 kg, and CFI <1.8 to guide cemented vs. cementless stem use.

In Otero Balda 2025 et al., on Short-term outcomes after feline cPSS surgery, which of the following was **not** significantly associated with 30-day survival in PANS-affected cats?
🔍 Key Findings
- 78% of cats that developed postattenuation neurologic signs (PANS) after congenital portosystemic shunt (cPSS) surgery survived to 30 days.
- Postattenuation seizures (PAS) were associated with significantly decreased 30-day survival (50% vs. 78%; OR: 0.015, p = .005).
- Treatment of PANS with propofol was a negative prognostic factor (OR: 0.112, p = .0008).
- Generalized PAS accounted for most seizure cases and were more frequently fatal than focal or unknown-type seizures.
- Pretreatment with levetiracetam (LEV1 protocol) showed a trend toward improved survival (100% vs. 60.6% in untreated cats), though not statistically significant (p = .06).
- Shunt morphology, method of attenuation, and study period (early vs. late) were not significantly associated with 30-day survival.
- Electrolyte, glucose, and ammonia abnormalities were not strongly linked to survival outcomes in this study.
- Majority of PAS-related deaths were due to uncontrolled generalized seizures or euthanasia because of severity.

In Motta 2026 et al., on feline shoulder arthrodesis, what was the primary advantage of using 3D-printed patient-specific surgical guides (PSG)?
🔍 Key Findings
- 3D-printed patient-specific guides (PSG) enabled accurate surgical planning and osteotomy execution for feline shoulder arthrodesis, improving control of humeroscapular alignment.
- Four cats with severe shoulder pathology (instability, osteoarthritis, recurrent luxation, or glenoid dysplasia) were treated successfully using CAD-planned osteotomies and PSG-assisted fixation.
- Preoperative CT-based planning standardized scapular and humeral axes, allowing planned scapulohumeral arthrodesis angles of 105–110°.
- Postoperative alignment closely matched planned angles, differing by only 2–5°, demonstrating high transfer accuracy from digital planning to surgery.
- All cats were weight-bearing within 48 hours, and long-term follow-up showed good to excellent functional outcomes with only mild mechanical lameness.
- Complications were minor and implant-related, including Kirschner wire migration and screw loosening, neither resulting in catastrophic failure.
- Double plating constructs provided strong stability, and the authors recommend compression or dual-plate fixation to reduce osteotomy strain and improve healing.
- PSG technology may reduce malalignment risk compared with traditional arthrodesis techniques, but requires CAD expertise, 3D-printing resources, and additional surgical planning time.

In Monnet 2023 et al., on barbed vs conventional suture in vesicourethral anastomosis (VUA), what was the median suturing time for the unidirectional barbed suture group (UBS)?
🔍 Key Findings
- Leakage pressure was not significantly different between unidirectional barbed suture (UBS) and conventional (C) suture groups (p = .236).
- UBS group had a 28% lower median leakage pressure than the C group (8.6 mmHg vs. 11.7 mmHg), suggesting higher biological risk of leakage.
- UBS significantly reduced suturing time (median 12.7 vs. 17.3 minutes; p < .0002).
- Fewer suture bites were needed in the UBS group (median 14 vs. 19; p = .012).
- No suture breakage or urethral narrowing occurred in either group.
- Leakage site distribution (ventral vs lateral) was similar between groups; no dorsal leaks noted.
- Leakage occurred as low as 5 mmHg in UBS group, indicating potential for postoperative extravasation.
- UBS may aid intracorporeal suturing in minimally invasive prostatectomy, but catheterization remains necessary postoperatively.
