In Peycke 2022 et al., on CBLO in immature dogs, which structure must be **avoided during osteotomy** to preserve growth potential?
🔍 Key Findings
- CBLO was effective for stifle stabilization in skeletally immature dogs with CrCL injuries, avoiding disruption of proximal tibial growth plates.
- Radiographic union of the osteotomy occurred in a mean of 6 weeks (range: 4–8 weeks), indicating rapid bone healing.
- Full limb function was restored in all cases by long-term follow-up (mean 23 months), including dogs with initial complications.
- Two dogs developed 19° valgus deformities due to screw interference with the proximal tibial physis; both were corrected surgically with return to function.
- One dog developed 10° recurvatum due to over-rotation of the tibial plateau, but retained full function without revision.
- CCS (countersink compression screw) caused early apophyseal closure in older dogs but had no adverse clinical effects.
- In contrast, K-wire or plate-only fixation preserved open apophysis, suggesting implant choice may influence growth.
- No meniscal injuries were observed, and all CrCL injuries were managed arthroscopically — 6 complete, 6 partial, 4 avulsions.

In Whitney 2022 et al., on CBLO fixation strength, which variable was found to have **no significant effect** on construct stiffness, yield load, or ultimate load in CBLO testing?
🔍 Key Findings
- CBLO fixation with both a headless compression screw (HCS) and tension band (TB) showed the highest yield and ultimate loads compared to other configurations
- HCSTB constructs had significantly higher yield load (1212 N) and ultimate load (1388 N) than Plate alone (788 N, 774 N), HCS alone (907 N, 927 N), or TB alone (1016 N, 1076 N)
- No difference in construct stiffness was detected among the four fixation methods tested
- All constructs ultimately failed by bone fracture—location of failure differed by construct type (e.g., through HCS hole or cranial screw hole)
- TB and HCSTB groups showed failure via progressive TB stretching and cranial osteotomy widening, while Plate and HCS failed more abruptly
- All constructs withstood forces exceeding expected quadriceps load in vivo (170–325 N), suggesting all methods can resist physiological loading, but HCSTB provides greater safety margin
- HCS alone was not significantly stronger than Plate or TB alone, questioning its standalone superiority
- Study supports using TB and HCS together for optimal construct strength, but clinical studies are needed to validate implant fatigue, healing, and failure rates

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 Chen 2024 et al., on pressure-measurement tools, how much does the risk of poor outcome increase per 1 mm Hg rise in portal pressure during complete PSS occlusion?
🔍 Key Findings
- WMg (water manometer with gauge) was the most accurate and precise pressure measurement device.
- APT (arterial pressure transducer) was less accurate than WMg but still precise; it differed significantly from the gold standard (WMr).
- CCT (Compass CT) was the least accurate and precise and differed significantly from the set pressure.
- Mean differences from set pressure were smallest for WMg (−0.020 cm H2O), moderate for APT (−0.390 cm H2O), and largest for CCT (−1.267 cm H2O).
- All devices showed excellent interobserver (ICC = 1.000) and intraobserver agreement (ICC range 0.985–0.998).
- Even though the CCT performed least well, all devices had mean errors ≤1.3 cm H2O, indicating potential clinical utility.
- WMg or WMr should be preferred in surgical settings due to superior accuracy and precision.
- Measurement precision is more critical than accuracy during PSS surgery, as a 1 mm Hg (~1.3 cm H2O) increase in portal pressure raises odds of poor outcomes by 9%.

In Muroi 2025 et al., on refracture risk, what bone quality indicator was significantly lower in dogs that refractured **after plate removal**?
🔍 Key Findings
- Refracture occurred in 5.5% of limbs, with higher incidence in the plate removal group (12.5%) vs. non-removal (3.5%).
- In the non-plate removal group, refractures occurred at the most distal screw site, linked to greater screw position change during growth (OR 1.79, p=0.04).
- Screw-to-bone diameter ratio (SBDR) >0.4 was a significant risk factor for refracture in the plate retention group.
- In the plate removal group, refractures occurred at the original fracture site, associated with lower pixel value ratio (bone mineral density) and reduced radial thickness.
- Implant-induced osteoporosis (IIO) beneath the plate likely contributed to refracture risk after plate removal.
- Younger age at fracture (<6 months) was associated with higher refracture risk due to ongoing radial growth and shifting screw position.
- No significant association was found between refracture and plate type (locking vs conventional), fixation method, or ulnar union.
- Recommendations include careful SBDR sizing, motion restriction, and cautious plate removal decisions in growing dogs.

In Banks 2023 et al., on TECA-LBO in brachycephalic dogs, which neurologic sign was most significantly more common in extreme brachycephalic breeds (EBBs) preoperatively?
🔍 Key Findings
- Extreme brachycephalic breeds (EBBs) presented more acutely and at younger ages, most often with neurological signs compared to other breeds.
- Preoperative signs such as facial nerve paresis, vestibular syndrome, and Horner’s syndrome were significantly more common in EBBs.
- EBBs showed more severe imaging findings, including higher rates of otitis interna (46.3% vs. 8.5%) and brainstem changes (17.5% vs. 3%).
- Intraoperative complications were more frequent in EBBs (11.1% vs. 5.3%), but this difference did not reach statistical significance (p = .078).
- Perioperative complication rates did not differ significantly between EBBs and other breeds (23.5% vs. 29.3%).
- Surgical time was significantly longer in EBBs (median 115 vs. 95 minutes; p = .011).
- MRI or combined CT/MRI were more frequently used in EBBs, likely due to the higher prevalence of neurological signs.
- Despite anatomical challenges, complication rates in EBBs were comparable, supporting TECA-LBO safety in these breeds.

In Sunlight 2022 et al., on Protein C monitoring, what was the average postoperative Protein C (PC) activity in dogs with excellent clinical outcomes?
🔍 Key Findings
- Postoperative Protein C (PC) activity increased in 78.7% of dogs, and was significantly higher in dogs with excellent clinical outcomes.
- Complete acute shunt occlusion resulted in higher postoperative PC activity (96.3%) and better ultimate clinical outcomes than incomplete occlusion.
- Preoperative PC was not predictive of clinical status, but postoperative PC was associated with improved outcomes.
- Standard biochemical markers (HCT, MCV, ALB, BUN) also improved postoperatively, especially in dogs with excellent clinical outcomes.
- Dogs requiring a second procedure had significantly lower postoperative PC (43.5%) than those not requiring further intervention (78.5%).
- Repeat procedures improved PC and BUN values, with PC increasing significantly after second intervention (to 69.8%).
- PC normalization (within reference interval) occurred in 87.5% of dogs with excellent clinical status, compared to only 12.5% in those with poor status.
- Clinical outcome classification (excellent/fair/poor) correlated with biochemical normalization and lack of need for diet/medications.

In Chik 2025 et al., on abdominal wall prestretching, which anatomical direction showed the greatest increase during insufflation?
🔍 Key Findings
- Prestretching (PS) at 10 mmHg for 3 minutes significantly increased working space at 6 mmHg IAP — IWL +4.4%, IWS +6.9%.
- PS provided ≈63% of the IWL and ≈66% of the IWS gains achieved with sustained 10 mmHg IAP.
- All laparoscopic procedures were completed at 6 mmHg after PS; no conversions or pressure increases were needed.
- Working space benefits persisted throughout surgery — end-of-procedure measurements were unchanged from post-PS baseline.
- Transverse expansion (RLAT/LLAT) was greater than sagittal (CRA/CAU), consistent with adult abdominal wall compliance.
- No adverse anesthetic events occurred; mild complications (e.g., gas leakage) were easily managed.
- Large breed dogs were overrepresented, but all dogs served as their own controls, normalizing size effects.
- Prestretching is a simple, effective technique to maximize working space without increasing insufflation pressure.
