In Mullen 2024 et al., on NIRF for GDV, what best describes the NIRF findings in stapled partial gastrectomy sites?
🔍 Key Findings
- NIRF altered surgical strategy in 3 of 20 GDV dogs, identifying necrosis not appreciated subjectively.
- Fundic fluorescence <10% indicated histologically confirmed gastric necrosis.
- In 1 dog, NIRF revealed nonviability despite the surgeon’s impression of viability.
- Staple line fluorescence resembled viable tissue in the only stapled gastrectomy, suggesting preservation of perfusion.
- GDV dogs (even “viable”) showed lower fluorescence vs. healthy controls, indicating subclinical vascular compromise.
- Histology confirmed full-thickness necrosis in all 4 dogs with NIRF-defined nonviability.
- Pre-op lactate was significantly higher in nonviable GDV dogs (8.55 vs 4.89 mmol/L, p=0.03).
- No complications were reported from ICG use; imaging was safe and repeatable.

In Anderson 2025 et al., on wound drain configurations, which configuration had the highest mean volume of fluid retrieved?
🔍 Key Findings
- Study Design: Cadaveric model using four large-breed dogs with 10x10 cm full-thickness wounds at four locations (shoulder, thorax, flank, thigh).
- Configurations Tested: Diagonal, opposite, parallel, and perpendicular placements of wound infusion catheter and JP drain.
- Fluid Retrieval:
- No significant difference by configuration (p = .92) or location (p = .32).
- Perpendicular configuration had the highest mean retrieval (11.35 mL, 56.8% of instilled volume).
- Flank location had the lowest retrieval (7.2 mL, 35.9%).
- Surface Area Coverage:
- Parallel configuration achieved the highest SA coverage (83.4% ± 11.6%, p < .01).
- Perpendicular was lowest.
- Leakage:
- No difference in leakage between configurations (p = .74) or locations (p = .10).
- Leakage commonly occurred at drain or catheter entry points (93.8% of wounds).
- Conclusion: Parallel drain configuration optimized fluid dispersion. Infusion-retrieval systems may allow for topical therapy delivery in closed wounds.

In Low 2025 et al., on machine-learning outcomes in IVDE, what was the most important predictor of outcome according to SHAP value analysis?
🔍 Key Findings
The study included 162 deep-pain-negative dogs undergoing decompressive surgery (hemilaminectomy) for acute thoracolumbar intervertebral disc extrusion (IVDE).
Ambulatory recovery occurred in 53.1% of dogs (86/162).
The best performing machine-learning model was XGBoost, with an AUC of 0.9502 and accuracy of 89.1%, outperforming Ridge, AdaBoost, and Naive Bayes models.
Preoperative-only XGBoost models were less accurate, with AUC dropping to 0.8271 and accuracy to 71.9%.
Top predictive features (by SHAP analysis) included:
- T2-weighted to L2 spinal cord signal ratio (lower values predicted better outcome)
- Use of fenestration (presence associated with better recovery)
- Hospitalization duration
- Imaging modality used
- Duration of nonambulatory status
Machine learning provided better insight into prognostic factors than traditional statistical methods.

In McClean 2025 et al., on shoulder arthrocentesis techniques, what proportion of SA injections resulted in cartilage injury (IACI)?
🔍 Key Findings
- Study Type: Cadaveric study using 36 paired canine shoulders (n = 18 per group: Subacromial [SA] and Supratubercular [ST])
- Survey Results: 75% of clinicians preferred SA technique; 25% used ST
- Complete accuracy: 50% (SA), 44% (ST) — no significant difference (p = .8)
- Partial accuracy: 39% (SA), 50% (ST)
- Complete miss: 11% (SA), 5.6% (ST)
- Incidence of IACI:
- SA: 50% (9/18 shoulders)
- ST: 11% (2/18 shoulders) → statistically significant (p = .007)
- Lesion depth: All ST lesions were partial-thickness; SA group had one full-thickness lesion (p = .027)
- Location: Lesions found on glenoid and humeral head with even distribution in SA; only one each in ST
- Landmark-guided injections were ≤50% completely accurate, even by an experienced operator.
- ST technique is safer with lower risk of cartilage damage, despite similar accuracy.
- Findings support considering image-guided techniques to improve both safety and accuracy in clinical settings.

In Philips 2025 et al., on radiographic IAIP detection, how did implants placed 2 mm into the joint perform in terms of accurate classification?
🔍 Key Findings
Overall accuracy of radiography to detect IAIP: 77.9%
Sensitivity: 97.2%
Specificity: 67.6%
False positive rate: 32.4% of non-penetrating implants were misclassified as penetrating
Implants directed toward the lateral tibial condyle had higher misclassification (23.8%) than medial (8.3%)
Most accurate detection: Implants placed 2 mm into the joint (97.2% correct classification)
Least agreement: For implants placed at 0 mm (subchondral level), especially lateral (AC1 = 0.48)
No palpable abnormalities (e.g., crepitus) observed during ROM for any group
No significant difference in detection by specialty field or reviewer qualification
Suggests radiographic misclassification risk and supports considering CT/fluoroscopy in equivocal cases

In Muroi 2024 et al., on radius plate stress effects, what FEA result was consistent in both LP 1 mm and 3 mm groups?
🔍 Key Findings Summary
- Finite element analysis compared intact radii vs. locking plates placed 1 mm or 3 mm above the bone
- LP placement significantly reduced tensile (maximum principal) stress on cranial cortex, potentially causing implant-induced osteoporosis
- Shell element findings:
- Max principal stress significantly lower in both LP groups vs. intact (p < 0.05)
- Solid element findings:
- Equivalent stress higher and max principal stress lower in LP groups
- Implication: Tension reduction may impair bone remodeling; implant design and placement height affect stress environment

In Kikuchi 2025 et al., on arthroscopic MMI in toy breeds, which factor was significantly associated with an increased risk of MMI?
🔍 Key Findings
- Medial meniscus injury (MMI) occurred in 36.3% of stifles with CrCLR in toy breed dogs (<5 kg)
- Complete CrCLR was significantly associated with MMI (15.3% of complete vs. 3.4% of partial)
- Severe lameness (grade 3) increased the likelihood of MMI compared to mild lameness (grade 1)
- Higher body weight, even within the toy breed range, was positively associated with MMI
- Yorkshire Terriers had the highest MMI incidence (55.6%), but this was not a significant independent factor due to multicollinearity
- Arthroscopy identified more meniscal damage (including small radial tears and bucket-handle lesions) than gross examination might detect
- MMI was classified as mild (radial tear) or severe (bucket-handle or flap) with implications for partial meniscectomy
- Arthroscopy was used in all cases, underscoring its utility in small-breed stifle assessment

🔍 Key Findings
Internal fixation (IF) group (n=59):
- Complication rate: 20.3%
- Major complications: 15.3%
- Longer time to discharge if complications occurred (median: 12.5 weeks)
External skeletal fixation (ESF) group (n=36):

- Use of post-op antibiotics associated with increased odds of complications (OR 3.53, p = .028)
Fixation choice influenced by age:
- Older puppies more likely to receive IF (OR 1.25 per week increase in age, p < .001)
Breed & fracture distribution:
- Common breeds: Labrador, Border Collie, Whippet
- Common fracture sites: middle and proximal third of tibia
