🔍 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.

🔍 Key Findings

Design: Ex vivo cadaver study (n=8 dogs, 24 sites)
Comparison: Freehand vs. 3D-printed drill guide-assisted ventral slot (GAVS vs FHVS)
Findings:

• GAVS produced slots not significantly different from planned dimensions (p = .722–.875)
• FHVS produced significantly shorter slots than intended (p < .01)
• No difference in surgical time (p = .071)
• Shape ratio and slot divergence from midline were similar between groups (p > .4)
• Use of guide significantly reduced variability in slot position (63% → 29%), shape (65% → 24%), and divergence (54% → 50%)

Conclusion: 3D-printed guides improved accuracy and consistency of ventral slot creation by novice surgeons; supports future evaluation in live dogs and small breeds

🔍 Key Findings

• Buccal transposition flap provided successful closure of large maxillary lip defects in all 5 dogs
• All flaps survived, with 3 dogs experiencing minor complications (e.g., fistulas, dehiscence) that resolved
• Flap vascularization originated from the angularis oris and superior labial arteries, as confirmed via CT angiography
• Excellent cosmetic and functional outcomes were achieved in all cases
• Ex vivo cadaver study validated flap perfusion, showing consistent contrast filling of key arteries
• Oronasal fistulas occurred in 2 dogs at the palatal incision site, likely due to contact with the mandibular canine tooth
• Mandibular canine coronectomy was performed in 2/5 dogs to prevent flap trauma
• Flap design and commissure positioning were customizable, aiding tension relief and improving outcomes

🔍 Key Findings

• Ex vivo study using 24 canine cadaver pelves to test screw thread direction in SI luxation.
• Four groups: RhRSI, RhLSI, LhRSI, LhLSI.
• Right-handed screws on right side (RhRSI) had 313% higher torque and 274% higher load vs left side (p < .01).
• Left-handed screws on left side (LhLSI) had 198% higher torque and 195% higher load vs right side (p < .03).
• All failures occurred due to rotation, with no screw breakage or fractures.
• Body weight and moment arm were similar across groups.
• Clinical implication: Use of screw matching handedness to luxation side improves stability.

🔍 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.

🔍 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%.

🔍 Key Findings Summary

• 95 TPLO procedures reviewed retrospectively with follow-up radiographs
• Rock-back defined as increase in tibial plateau angle (TPA) ≥2° from immediate post-op to recheck
• 21% of stifles (20/95) experienced rock-back
• Mean ΔTPA among rock-back cases = 3.2° ± 2.6°
• No implant failures or tibial tuberosity fractures were reported in these cases
• Plate inclination and exit cut angle (ECA) were not associated with increased risk of rock-back (p = 0.4 and 0.2)
• Authors hypothesize that compression across osteotomy in vivo may mitigate torsional effects from ECA, unlike in gap-model studies
• Emphasizes that rock-back is relatively common, even with well-placed implants

🔍 Key Findings

• Spinal stabilization with 3D-printed patient-specific drill guides (3D-PSGs) was safe, with no immediate perioperative complications reported.
• 84% of pedicle screws were optimally placed, and only 0.5% breached the spinal canal, reflecting high placement accuracy.
• 80% of dogs experienced no neurologic deterioration postoperatively, indicating reliable short-term safety.
• 3D-PSGs were accurate and reproducible, even across multiple institutions and surgeons.
• Mid-term outcomes were favorable: all dogs were ambulatory, and 90% had static or improved neurologic signs.
• 7 of 10 mid-term follow-ups showed abnormal gait, though owners rated lifestyle ≥3/5, suggesting acceptable function.
• 3D-printed guides enabled precise pedicle screw placement in deformed vertebrae, expanding options in small breeds.
• One dog suffered a T4 spinous process fracture due to overextension of PMMA cement, emphasizing the need for cement placement caution.

🔍 Key Findings

• CBPI, COI, and LOAD are recommended for assessing canine osteoarthritis based on COSMIN criteria.
• COI scored highest in development rigor and evidence quality among evaluated OROMs.
• Internal consistency, reliability, and responsiveness were commonly validated, though no OROMs reported measurement error.
• LOAD was considered formative, and internal consistency assessment was deemed unnecessary.
• CBPI and COI showed sufficient internal consistency, but CBPI’s factor structure was inconsistent across studies.
• All 6 evaluated OROMs (CBPI, COI, LOAD, BHSII, HCPI, HVAS) were quick to complete (under 5 min).
• Three tools—BHSII, HCPI, HVAS—need more evidence before recommendation; only CBPI, COI, and LOAD are Category A (recommended).
• Future studies should assess interpretability, including measurement error and clinically meaningful change scores (MIC, SDC).

🔍 Key Findings

• Delayed union occurred in 13.9% of fractures; non-union in 4.6%; mal-union in 0.7%
• Major implant failure increased odds of delayed or non-union by 12.9×
• Surgical site infection increased risk 3.2×; bone grafting (any type) was also associated (OR 3.3)
• Comminuted fractures had 4.2× greater odds of delayed or non-union
• Older age increased risk, with odds increasing by 21% per year
• Radius and ulna fractures in toy breeds were not high risk, contrary to historical belief
• Most non-unions required revision surgery with rhBMP-2 or autograft to achieve union
• Ilium fractures showed 0% delayed/non-union — possibly due to robust muscle envelope
