In Gutbrod 2024 et al., on feline tibial stabilization, what was the mode of failure in all biomechanical tests across constructs?
🔍 Key Findings
- 2.4 mm LCP with a 1.6 mm IM pin had the highest axial stiffness and yield strength among the tested constructs.
- Axial stiffness was significantly higher in the 2.4 mm LCP + 1.6 mm IM pin group compared to 2.7 mm LCP alone (p = .013).
- No significant difference in torsional stiffness was found among groups.
- 2.4 mm LCP + 1.0 mm pin had the lowest stiffness and failure load, underperforming both other constructs.
- All constructs failed via valgus bending, consistent with clinical observations in feline tibial fractures.
- A 1.6 mm pin (~50% canal fill) resulted in superior construct performance vs. 1.0 mm (~30% fill).
- Group 2 (2.4 LCP + 1.6 mm pin) outperformed the 2.7 mm LCP alone in stiffness, despite using a smaller plate.
- Plate–rod constructs may better preserve periosteal blood supply and support minimally invasive stabilization strategies.

In Evers 2022 et al., on bone-to-tendon plate fixation, what fixation technique was used to secure the plate to the tendon?
🔍 Key Findings
- Bone-to-tendon plate fixation allowed successful stabilization of a highly comminuted calcaneus fracture in a dog with fragments too small for traditional fixation.
- The plate was sutured to the common calcaneal tendon using a figure-of-8 pattern, bypassing the need for screw fixation into small proximal fragments.
- Radiographic union was achieved by 17 weeks, though considered delayed, with the dog returning to normal function by 36 weeks post-op.
- A second surgery was required to replace the tendon-anchored plate with a calcaneus-only plate due to skin ulceration and implant prominence.
- Implant-associated infection was suspected; cultures confirmed Staphylococcus pseudintermedius, managed with doxycycline and clindamycin.
- Use of human placental matrix (hPM) and both autogenous and allogenic bone grafts supported healing, though their specific contribution remains uncertain.
- Postoperative complications included delayed union and skin ulceration, emphasizing challenges of implant design and soft tissue management.
- This is the first report of using a bone-to-tendon plate for a calcaneus fracture in dogs and demonstrates its potential in cases where traditional methods are not viable.

In Galliano 2022 et al., on vascular access ports, what was the reported functionality rate of ports placed in the femoral/external iliac vein (fSVAP)?
🔍 Key Findings
- SVAPs placed in axillary (aSVAP) or femoral/external iliac veins (fSVAP) during limb amputation remained functional in 92.3% and 100% of cases, respectively.
- Complication rates were lower in aSVAP (23.1%) and fSVAP (0%) compared to jSVAP (47.4%), although not statistically significant (P = .12).
- No catastrophic complications occurred with aSVAP or fSVAP; 2 deaths occurred with jSVAP due to port-related issues.
- Infection-related port removal was needed in 1 aSVAP (7.7%) and 2 jSVAPs (10.5%) — no removals were required in fSVAPs.
- Tip placement of the catheter (e.g., right atrium vs. vena cava) did not correlate with complications (P = .66).
- Shorter surgical time likely with aSVAP/fSVAP as they use the same surgical field as the limb amputation.
- Survival time median was similar across groups (jSVAP: 177 days, aSVAP: 125 days, fSVAP: 122 days).
- SVAP implantation during limb amputation offers a practical and safe alternative to separate jugular placement.

In Sisk 2024 et al., what conclusion did the authors draw regarding reamed versus unreamed IMN in dogs?
🔍 Key Findings Summary
- IMN provides relative stability, resists bending/torsion due to central axis alignment
- Larger diameter nails = exponentially greater stiffness (∝ D⁴)
- Trade-off: Larger interlocking holes weaken fatigue strength of the nail
- Reaming increases contact/stability but has pros/cons:
- Improves outcomes in closed fractures
- May reduce endosteal blood flow in thin-walled bones (e.g., cats)
- Design advances:
- Angle-stable IMN reduce rotational slack
- Expandable nails simplify insertion but may compromise removal or compressive load resistance
- Precontoured nails match bone curvature but lack consistent clinical superiority
- Material debates continue (e.g., titanium vs. stainless steel vs. magnesium)

In Price 2024 et al., on left-sided TD ligation in dogs, which procedure was successfully completed via the same incision as TD ligation?
🔍 Key Findings
- Left fourth intercostal thoracotomy allowed successful thoracic duct (TD) ligation in 9/10 canine cadavers.
- 10/13 clinical cases had a single TD branch at the left fourth intercostal space, indicating lower anatomical complexity.
- All TD branches at this site were lateral to the esophagus, simplifying surgical access.
- Unilateral subphrenic pericardiectomy was successfully performed via the same incision in 10/10 cadavers.
- Fewer TD branches at the fourth intercostal space than traditional caudal sites may reduce the risk of missed collaterals.
- In contrast, traditional caudal TD ligation sites had up to 5 branches, requiring broader dissection.
- No cadaver had right-sided TD branches, reducing surgical complexity at the studied location.
- Contrast-confirmed ligation was effective in 90% (9/10) cadavers on CT imaging.

In Knudsen 2024 et al., on CTA diagnosis, what was the observed **negative likelihood ratio (NLR)** of CTA for meniscal lesion detection in second readings?
🔍 Key Findings
- Multidetector CTA had high sensitivity (up to 100%) and specificity (up to 96%) for detecting medial meniscal tears in dogs.
- Observer experience significantly influenced diagnostic accuracy, with more experienced observers showing higher agreement and better performance.
- Training effect was evident, as less experienced observers improved between first and second readings.
- Positive likelihood ratios ≥4.6 and negative likelihood ratios ≤0.08 were observed, suggesting CTA is clinically useful for confirming or ruling out meniscal injury.
- CTA allowed identification of full and partial thickness lesions, with good visualization in sagittal, transverse, and frontal reconstructions.
- Approximately 90% of menisci were correctly classified in second readings.
- No adverse reactions were noted from the contrast injection; sedation was used instead of general anesthesia.
- CTA was less invasive and potentially more cost-effective compared to arthroscopy, especially in settings without MRI access.

In Pilot 2022 et al., on closure methods in sternotomy, what was concluded regarding closure technique choice in large dogs?
🔍 Key Findings
- Overall closure-related complication rate was 14.1%, lower than previously reported (17–78%).
- No clinically meaningful difference in complication rate between orthopedic wire (17.4%) and suture (11.5%) closure methods.
- Dog size (≥20 kg) was the only significant risk factor associated with increased closure-related complications (p = .01).
- Type of closure (wire vs. suture) did not affect risk, even in larger dogs.
- Suture closure showed a non-significant trend toward fewer complications (mean reduction 2.3%, 95% CI: –9.1% to +4.5%).
- Most complications were mild (62%), with only 10 severe cases requiring surgical revision.
- Infection rate was low (2.7%), and not significantly different between wire and suture.
- Suture closure is a valid alternative to wire, including in large dogs, based on this large, multi-institutional study.

In Buote 2023 et al., on 3D printed cannulas, what was the primary benefit observed in cadaver surgeries when using 3D printed cannulas (3DPCs)?
🔍 Key Findings
- Customized 3D printed cannulas (3DPCs) significantly reduced surgical time in feline cadaver models (125.6 vs. 95.2 min, p = 0.03).
- Use of 3DPCs resulted in a reduction in instrument collisions (6.8 vs. 2.6, p = 0.03).
- Cannula pullout complications decreased with 3DPCs (10 vs. 2.2 per procedure, p = 0.03).
- 3DPCs were designed at shorter lengths (3 cm), improving intra-abdominal working space in cats.
- No incisional or postoperative complications occurred in the two live feline cases.
- One 3DPC insufflation port broke intraoperatively; resolved by using a male luer lock connector in the next case.
- CO₂ leakage occurred from re-used silicone valves in 2 ports; emphasizing the need for durable valve design.
- Estimated cost per 3DPC was <$5.00, suggesting cost-effective customization for feline laparoscopy.
