In Mcclean 2026 et al., on stifle arthrocentesis techniques, where were cartilage injuries caused by the POUCH technique primarily located?
🔍 Key Findings
- All four arthrocentesis techniques achieved 100% intra-articular accuracy, confirming that each landmark-guided method could successfully access the canine stifle joint.
- Lateral intercondylar notch (LINC) was the most commonly used technique clinically, reported by 87.5% (35/40) of surveyed surgeons.
- INFRA and SUPRA required significantly more needle repositions (median 3 and 2) compared with LINC and POUCH (median 1) (p = .001).
- No iatrogenic articular cartilage injury (IACI) occurred with LINC or SUPRA techniques, suggesting favorable safety profiles.
- INFRA produced the highest IACI rate (75%), with 6/8 limbs affected, indicating substantial risk with this approach.
- More than half of INFRA injuries exceeded 10 mm² and involved weight-bearing cartilage, raising concern for clinically significant joint damage.
- POUCH technique caused IACI in 37.5% of cases, but injuries occurred exclusively on non-weight-bearing cartilage.
- SUPRA (suprapatellar) approach demonstrated accuracy with zero cartilage injury, making it a promising safer alternative for stifle arthrocentesis pending clinical validation.

In Tani 2022 et al., on FCU tendon reconstruction, what was the main reason for using a fascia lata autograft in Case 1?
🔍 Key Findings
- Fascia lata autograft reconstruction of the FCU tendon successfully treated carpal hyperextension in both dogs.
- Primary repair was not possible in one dog due to complete rupture; a fascia lata graft bridged the tendon gap.
- In the second case, elongated tendon was corrected and reinforced with fascia lata to prevent recurrence.
- Type I external skeletal fixation was used for 6 weeks to support tendon healing in both dogs.
- Postoperative gait and range of motion returned to normal, with no recurrence at 36-month follow-up.
- Ultrasonography aided diagnosis, revealing thinning and echogenic changes in the FCU tendon.
- Histologic findings showed mild, nonspecific muscle changes, suggesting injury rather than a systemic disease.
- No complications occurred, and fascia lata showed potential for biological integration and remodeling into tendon-like structure.

🔍 Key Findings
- Ventral Compression Index (VCI) ≥0.16 (extension) or ≥0.2 (flexion) was diagnostic for AAI with 100% sensitivity and >94% specificity
- VCI had the highest diagnostic accuracy among all measured variables (AUC > 0.99)
- C1-C2 overlap ≤2.7 mm (extension) or ≤1.8 mm (flexion) also diagnostic for AAI (sensitivity 84–96%, specificity 81–90%)

In Hawker 2025 et al., on locking head inserts, what did the authors conclude regarding high-strain construct scenarios?
🔍 Key Findings
- Adding Locking Head Inserts (LHI) to a 3.5-mm LCP had no effect on plate strain, stiffness, or deformation in an open fracture gap model.
- Peak strain consistently occurred at the Combi-hole over the fracture gap, with values up to ~1837 µε.
- No significant difference in strain was found across configurations with 0, 3, or 9 LHI (p = 0.847).
- Construct stiffness and compressive displacement also remained unchanged regardless of LHI count (p = 0.311 and 0.069 respectively).
- Study contradicted the hypothesis that LHI would reduce strain and increase stiffness under biologic loading.
- Combi-hole design may limit the efficacy of LHI, as LHI only fill the locking portion, not the compression side where strain peaks.
- Implant fatigue risk remains highest over unfilled screw holes, especially over fracture sites—confirming previous failure patterns.
- Surgeons should consider alternative methods to reduce strain when facing high implant load scenarios.

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.

In Welsh 2025 et al., on orthogonal plating, what change was consistently noted in all 3.5 mm plates?
🔍 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 Monti 2025 et al., on lymph node fluorescence imaging, what was the most common intraoperative complication encountered during NIRF-ICG guided laparoscopic ISLN excision?
🔍 Key Findings
- Laparoscopic ISLN removal using NIRF-ICG was feasible in 89% of dogs (16/18), demonstrating high procedural success with minimal invasiveness.
- Median laparoscopic dissection time was only 12 minutes, suggesting efficiency of the NIRF-guided approach.
- No postoperative complications were observed, and intraoperative complications occurred in only 2 dogs (11.1%), both requiring conversion to open surgery.
- Metastatic disease was confirmed in 48% of patients (12/25 nodes), including cases where LNs appeared normal in size, highlighting the value of histologic evaluation.
- NIRF-ICG enabled precise identification of small and mildly enlarged nodes, which are often missed during traditional imaging or palpation.
- Fluorescent dye leakage following LN capsule rupture limited visibility and required surgical conversion, indicating a key limitation of the technique.
- ICG signal was occasionally absent in metastatic LNs, likely due to lymphatic rerouting or obstruction, underscoring limitations in SLN identification.
- The lateral approach allowed consistent access to ipsilateral MILN, IILN, and sacral LNs, though contralateral nodes were inaccessible with this method.

In Barrett 2026 et al., on scapula plating biomechanics, where was the secondary plate placed to maximize biomechanical advantage?
🔍 Key Findings
- Double plate fixation significantly increased construct stiffness (563.7 vs 392.8 N/mm; p < .0001), supporting superior biomechanical stability
- Displacement was significantly reduced with double plating (−0.48 mm vs −0.81 mm; p < .0001), indicating improved resistance to cyclic loading
- No difference in primary plate strain between single and double constructs, suggesting load-sharing did not reduce plate stress
- Caudolateral placement of the second plate enhances biomechanical advantage by increasing moment arm and resisting tensile forces
- Cyclic loading model (7200 cycles) simulated 1 hour of walking, making findings clinically relevant to early postoperative activity
- Strain across fracture gap was lower in double plate constructs (~4.3% vs ~6.9%), supporting improved conditions for fracture healing
- No construct failures occurred, but actuator slippage occurred only in double plate group, highlighting potential testing/artifact considerations
- Clinical implication: double plating may allow earlier weightbearing and reduce need for external coaptation, improving recovery outcomes
