In Clarke 2022 et al., on nasopharyngeal collapse severity, which diagnostic modality was used to quantify pharyngeal collapse in awake dogs?
🔍 Key Findings
- Nasopharyngeal collapse was significantly more severe in brachycephalic dogs (median 65%) than in nonbrachycephalic controls (median 10%) (p = .0001).
- Postoperative fluoroscopy showed no significant improvement in nasopharyngeal collapse (p = .0505), despite reported clinical improvement.
- 70% of brachycephalic dogs had ≥50% collapse; 26% had 100% collapse preoperatively.
- All owners of surgical cases reported clinical improvement, including reduced respiratory noise and improved exercise tolerance.
- Surgical techniques used included combinations of alaplasty, staphylectomy, sacculectomy, and tonsillectomy.
- Improvement in nasopharyngeal dimensions was variable, with some dogs improving ≥45%, some worsening, and one dog showing a 100% increase post-op.
- Pharyngeal collapse may not be solely anatomical; neuromuscular dysfunction (e.g., reduced pharyngeal dilator muscle function) may contribute.
- Current surgical techniques may not address functional airway abnormalities, suggesting a need for multimodal or targeted interventions.

In Sullivan 2025 et al., on TTT stabilization methods, which stabilization method showed significantly different failure force or stiffness?
🔍 Key Findings
- Spacer pin fixation showed no difference in failure force or stiffness compared to tension band wire (TBW) or 2-pin techniques.
- All constructs failed under loads >1000 N, exceeding estimated peak quadriceps force in dogs during walking (~240 N).
- Patellar ligament failure was the most common mode of failure across all groups (5–8 samples per group).
- Distal tibial crest fractures were seen only in 2-pin and spacer pin groups, not in TBW group, suggesting TBW may protect against crest failure.
- No failures occurred at pin tracts, possibly due to pin placement within patellar ligament footprint.
- Spacer pin technique avoids placing pins through the tuberosity, potentially reducing risks of soft tissue complications like tendinopathy or irritation.
- Use of partial osteotomy with robust distal crest may substitute for TBW without compromising initial mechanical strength.
- Further in vivo or cyclic loading studies are required, as this cadaveric study tested only acute tensile failure.

In Trefny 2025 et al., on locking plate biomechanics, when did transcortical contact occur in long working length constructs?
🔍 Key Findings
- Short working length constructs had significantly higher stiffness and lower strain than long constructs in compression bending (p = 0.0172).
- In tension bending, short constructs also had higher precontact stiffness and lower strain, but this reversed after transcortical contact (~150 N).
- Transcortical contact increased stiffness only in long constructs, producing a bilinear load-displacement curve.
- Postcontact stiffness was higher in long constructs, but this may not reflect clinical benefit due to risks of high interfragmentary strain.
- Short working length reduced strain at multiple ROIs under both loading conditions, including over fracture gap (Tables 1–3).
- Increased working length promoted stress concentration and deformation, especially in compression bending.
- In vitro benefits of long constructs (via contact stability) may not translate to healing, as repetitive loading could increase plate strain and bone resorption.
- Plate strain was effectively mapped using 3D digital image correlation, confirming regional strain differences between configurations.

In Planchamp 2022 et al., on imaging-based AAI diagnosis, which measurement had the highest diagnostic accuracy in both head positions?
🔍 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 Danielski 2025 et al., on PUO complication reduction, how did **IM pin breakage** affect clinical outcomes?
🔍 Key Findings
- Combined intramedullary (IM) pin and rhBMP-2 use resulted in a low complication rate (7.4%) after proximal ulnar osteotomy (PUO).
- Major complications occurred in 5.3% of cases (4 infections, 1 pin breakage with ulnar tilt requiring revision).
- Minor complications occurred in 2.1% of cases (seroma, delayed union).
- No cases of non-union were observed; 98.9% of limbs achieved radiographic healing by 6 weeks.
- IM pin breakage was noted in 11.8% of limbs but did not affect healing outcomes.
- Chondrodystrophic breeds made up 64.8% of the cohort and tolerated the procedure well.
- Compared to prior studies, complication rates were substantially reduced with this technique (prior major: 13.9%; this study: 5.3%).
- The use of rhBMP-2 likely enhanced early bone healing and provided biologic support, particularly important in breeds at higher risk of complications.

🔍 Key Findings
Increased risk with gonadectomy:
- Pooled OR for CrCLD:
- Females: 2.29 (95% CI: 1.77–2.95)
- Males: 2.12 (95% CI: 1.67–2.69)
Early gonadectomy (≤1 year) further increased risk:
- OR vs >1 year:
- Females: 3.39
- Males: 3.13
Late gonadectomy (>1 year) had no significant difference vs intact dogs.
Breed-specific findings:
- Female Labradors: No increased CrCLD risk from gonadectomy (OR = 1.19; 95% CI: 0.54–2.64)
- Male Labradors: Increased risk persisted (OR = 2.13; 95% CI: 1.53–2.98)
Study type: Systematic review + meta-analysis of 24 observational studies (n = 1.85 million dogs)

In Buote 2023 et al., on feline laparoscopic cannulas, how did the **instrument collision rate** change when using 3D printed cannulas compared to traditional ports?
🔍 Key Findings
- 3D-printed cannulas (3DPCs) reduced mean surgical time significantly in cadaveric procedures (125.6 vs 95.2 min, p = 0.03).
- Cannula pullout events decreased from a mean of 10 to 2.2 per procedure when using only 3DPCs (p = 0.03).
- Instrument collisions were significantly fewer with 3DPCs (6.8 vs 2.6 collisions, p = 0.03).
- Live patients experienced no postoperative complications, including no incision site infections or discomfort.
- Initial versions of 3DPCs had minor issues, including valve leakage and looser trocar fit, requiring surgical workarounds.
- Customization of cannula shaft length (3 cm vs standard 5–8.3 cm) improved working space and reduced instrument interference.
- Production cost was under $5 per cannula, suggesting 3DPCs may be a cost-effective and reusable alternative for small patients.
- Study supports broader use of 3DPCs in laparoscopic procedures requiring long-jawed instruments or intricate tissue handling.

In Davis 2025 et al., on modified anal sacculectomy, what was the most common complication grade reported postoperatively?
🔍 Key Findings
50 dogs underwent bilateral anal sacculectomy using a modified closed technique.
Intraoperative anal sac perforation occurred in 5 dogs (10%), with no postoperative complications in those dogs.
Postoperative complications (43 dogs with follow-up):
- Grade 1 (e.g., scooting, inappropriate defecation): 14/43 (32%)
- Grade 2 (medical treatment needed): 2/43 (5%)
- Grade 3B (revision surgery): 2/43 (5%)
93% of grade 1 and 100% of grade 2–3B complications resolved by two weeks postop.
Technique highlights: direct duct tracking, no anal sac packing, minimal dissection.
