In Barrett 2023 et al., on complication grading systems, what is an example of a **Grade I complication** in the aCD system?
🔍 Key Findings
- Cook system had good reliability across all cases (ICC = 0.848), even when complications, sequelae, and failure-to-cure were included.
- aCD system had excellent reliability when excluding sequelae/failure-to-cure cases (ICC = 0.975) but only moderate reliability when including them (ICC = 0.620).
- Majority of complications (60–63%) were graded as Grade 3 in the aCD system, corresponding to surgical or anesthetic intervention.
- Cook system classified most cases (78–81%) as major complications.
- Assessors had difficulty distinguishing sequelae from Grade 1 complications, and failure-to-cure from Grades 1–2, reducing aCD reliability.
- The aCD system offers more resolution (5 grades vs. 3) and less subjectivity through objective definitions.
- Novel terminology (e.g., sequelae, failure to cure) in the aCD system may hinder its uptake without proper training.
- Reclassifying expected events (e.g., swelling, bruising) as sequelae could significantly reduce reported complication rates in other studies.

In Welsh 2025 et al., on orthogonal plating, which configuration had the highest axial stiffness during static load testing?
🔍 Key Findings
- Compared unilateral plating (UP) vs orthogonal plating (OP) with 2.0, 2.4, and 3.0 mm plates (OP2.0, OP2.4, OP3.0).
- Model: acetal homopolymer (Delrin) rod with 29 mm fixed fracture gap, loaded axially (4–196 N, 90,000 cycles).
- OP constructs had 2.5–4.1x higher strength and 3.0–4.2x higher stiffness than UP constructs (p < .0002).
- UP had 3.5–4.1x higher gap strain than OP groups (p < .0075).
- All OP groups exceeded 1000 N max load before failure (vs 424 N for UP).
- Greater implant size in OP groups further increased performance.
- All constructs survived fatigue loading; 3.5 mm plates showed deformation, especially UP; OP plates remained intact.

In Power 2022 et al., on liposomal bupivacaine use, what was the overall incidence of short-term incisional complications in dogs?
🔍 Key Findings
- Overall complication rate was 19.7% (43/218), with most being mild (CSS 1).
- Soft tissue procedures had higher complication rates (26%) than orthopedic procedures (11.6%) (P < 0.01).
- No difference in complication rates between clean, clean-contaminated, and contaminated wounds (P = 0.55).
- No difference in complication rates between labeled use (CCL surgery) and off-label orthopedic procedures (P = 0.21).
- Majority of complications (63%) were mild, resolving without intervention or with topical therapy.
- Severe complications requiring revision surgery were rare (2.3%) and occurred mainly in soft-tissue surgeries.
- Most common complications included SSI (25.6%), dehiscence (16.3%), and seroma (14%).
- Liposomal bupivacaine appears safe for use in broader orthopedic procedures beyond current labeling.

In Thomsen 2024 et al., on CT accuracy for liver tumors, CT accuracy was NOT significantly influenced by which of the following?
🔍 Key Findings
- CT localization of liver masses was more accurate by division (88%) than by lobe (74.3%)
- Inter-radiologist agreement was excellent for division (kappa up to 0.885) and only moderate–good for lobe
- Quadrate and right lateral lobes had significantly lower localization accuracy compared to left lateral or medial lobes
- CT localization of the left division was most accurate (90.1%) compared to central (77.1%) and right (88.3%)
- Portal and hepatic venous phases were equally helpful for localization (each ~30–38% usefulness)
- No significant associations found between histopathologic diagnosis and localization accuracy
- Lobe-level CT localization should be interpreted with caution, especially for the quadrate and right lateral lobes
- Radiologist experience likely influenced accuracy, with the most experienced radiologist performing best

In Maeta 2022 et al., on total cystectomy in cats, how was urinary incontinence managed postoperatively?
🔍 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.

In Brisimi 2022 et al., on tracheal anastomosis tension, which statement is true?
🔍 Key Findings
- Tracheal anastomoses in immature dogs failed at significantly lower distraction forces (44.91 ± 59.03 N) than in adults (149.31 ± 45.36 N; _P_ = .007).
- Immature tracheae tolerated significantly more elongation before failure (39.75 ± 5.45%) than adult tracheae (30.57 ± 7.19%; _P_ = .0012).
- All constructs failed by suture tearing through the annular ligament, primarily near the dorsal tracheal ring.
- Overlapping of tracheal ends was seen in 50% of specimens across both age groups, suggesting limitations in tissue apposition with the chosen technique.
- Simple continuous pattern using 2-0 polypropylene was used; this pattern provides superior tensile strength compared to simple interrupted, but apposition may be suboptimal.
- Tracheal elasticity in immature dogs may allow longer resections, but the lower tensile strength necessitates reinforcement.
- Annular ligament-cartilage technique with 4-mm suture spacing showed variable results; smaller bites and nylon suture may improve outcomes.
- Ex vivo setup using frozen-thawed tracheae is a limitation, but prior studies support comparability with fresh tissue.

In Kennedy 2024 et al., which portal had the highest rate of articular cartilage injury?
🔍 Key Findings Summary
- 20 shoulders from 11 medium-to-large breed dogs evaluated
- Lateral portals used: middle arthroscopic, caudal instrument, cranial egress
- Musculotendinous lesions unavoidable, but small (18G needle); seen in deltoideus (90%), infraspinatus, teres minor, etc.
- Neurovascular safety:
- Caudal portal was closest to axillary artery/nerve branches (as close as 7 mm)
- Only 2/20 shoulders (10%) had omobrachial vein penetrated
- Cartilage injuries (IACI) occurred in 65%, primarily minor linear defects; use of guarded cannulas and distractors suggested for minimization
- Supports overall safety of lateral shoulder arthroscopy with portal placement awareness

In Perez Neto 2025 et al., on hip resurfacing arthroplasty, which biomechanical variables were NOT significantly different between prosthetic and intact femurs?
🔍 Key Findings
- In an ex vivo study of 20 canine femur pairs, implantation of a novel hip resurfacing arthroplasty (HRA) prosthesis reduced maximum load (ML) by 22% and load at collapse (LC) by 27% vs. intact controls (p ≤ 0.05).
- Displacement at maximum load (DML), displacement at collapse (DC), and stiffness (k) were not significantly different between prosthesis and control groups.
- Both groups showed similar failure patterns, with 92% failing at the femoral neck.
- All prosthetic femurs still withstood ~6.2× body weight — exceeding estimated in vivo peak loads (~1.64× BW).
- Prosthesis positioning (neutral vs valgus) had no significant effect on biomechanical outcomes.
- Implant design preserved more metaphyseal bone stock than total hip replacement, possibly explaining the smaller load reduction compared to other short-stem prostheses.
- The press-fit cobalt–chromium design with conical stem allowed full contact and stress distribution over the femoral head/neck.
- Authors conclude the device has adequate immediate biomechanical strength for clinical use, though long-term in vivo studies are needed.
