In Trefny 2025 et al., on locking plate biomechanics, what effect did transcortical contact have on 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 Kuvaldina 2023 et al., in Minimally invasive axillary lymphadenectomy in dogs, what anatomical variation was noted during cadaver dissection?
🔍 Key Findings
- A minimally invasive endoscopic technique was successfully developed for excisional biopsy of axillary lymph nodes in dogs.
- The procedure was performed on 4 cadavers (6 limbs) and 3 clinical patients, with no major complications reported.
- Mean cadaveric time: accessory axillary node 5.1 min; axillary node 33 min. One limb had a double axillary node.
- In clinical cases, 2/3 were completed endoscopically; one required conversion to open due to node elevation difficulty.
- Surgical times in clinical cases ranged from 35 to 58 minutes, depending on node accessibility and number.
- Postoperative morbidity was minimal: no lymphedema, minor seroma or lameness resolved quickly.
- The SILS port approach enabled effective access, though precise placement was critical to visualization.
- This is the first reported veterinary endoscopic technique for axillary lymphadenectomy; potential for improved staging and reduced morbidity.

In Guevara 2024 et al., on implant placement accuracy, what was the rate of acceptable pin placement using 3D-printed guides?
🔍 Key Findings:
- Sample: 24 canine cadavers, 477 total pins across 240 vertebrae.
- Technique Comparison: 3D printed guides (3DPG) vs freehand (FH).
- Acceptable Placement Rates: 3DPG = 87.5%, FH = 69.8% (p < .0001).
- Odds Ratio for FH: 0.28 (95% CI 0.16–0.47), significantly less likely to yield acceptable placement.
- Worst Accuracy Locations: T10 (OR 0.10), T11 (OR 0.35).
- Surgeon Impact: Surgeon 2 outperformed others (OR 9.61, p = .001).
- Modified Zdichavsky Classification used to score implant accuracy (Grades I–IIIb).
- Primary Benefit of 3DPG: Increased safety and precision, regardless of surgeon experience.

In Neal 2023 et al., on transcondylar screw placement, which method had lower screw eccentricity on the humeral condyle?
🔍 Key Findings
- Aiming device provided comparable trajectory accuracy to fluoroscopy, especially in right limbs (1.9° vs. 3.4°, p = .0128).
- Eccentricity (deviation from condylar center) was lower with fluoroscopy (3.1 mm vs 4.2 mm, p = .0017), making fluoroscopy more precise.
- Odds of joint infringement were 8× higher with the aiming device, though not statistically significant (p = .0575).
- Residents had greater screw trajectory deviation than diplomates (p = .0366), highlighting impact of experience.
- Aiming device procedures took less time than fluoroscopy in some scenarios, particularly for right limbs with right-handed surgeons.
- Fluoroscopic procedures had more pin/drill attempts, increasing risk of glove puncture and potential aseptic breaks.
- Mean deviation angles in both groups (<3.5°) were within acceptable range to avoid intracondylar fracture gap.
- Cadaver model used large-breed, healthy adult dogs, not small-breed immature dogs, limiting generalizability.

In Knudsen 2024 et al., on CTA diagnosis, what factor most significantly influenced diagnostic agreement and performance in CTA 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 Maeta 2022 et al., on total cystectomy in cats, what describes the surgical modification to the ureter for the stomal anastomosis?
🔍 Key Findings
- First reported case of total cystectomy and bilateral cutaneous ureterostomy in a cat using a modified Toyoda technique.
- Histologically complete tumor resection was achieved, with tumor-free ureter and urethral margins >20 mm.
- The modified Toyoda technique involved shaping the ureter into a fish-mouth aperture and anastomosing it to a rectangular skin defect for stomal formation.
- Incontinence was managed using a diaper changed every 6–8 hours, with no dermatological complications.
- Obstruction of the right ureter occurred 14 months post-op, associated with a subcutaneous nodule at the anastomosis site.
- Despite incontinence, owner satisfaction and perceived quality of life were high, with the cat living ~16 months post-op.
- The stents were removed on days 7 (left) and 28 (right) postoperatively, with initial patency maintained until 14 months.
- This surgical approach may offer palliative or curative benefit for feline trigonal TCC where partial cystectomy is not feasible.
