In Zann 2023 et al., In Long-term outcomes after proximal humeral OC debridement in dogs, what did CT reveal compared to radiography for lesion size assessment?
🔍 Key Findings
- 20 dogs (26 shoulders) evaluated at mean 3.5 years post-surgery after arthroscopic or open debridement.
- Ipsilateral muscle atrophy and decreased range of motion (↓ extension, ↓ flexion) in affected limbs compared to contralateral healthy shoulders.
- All treated shoulders developed osteoarthritis, confirmed radiographically, by CT, and arthroscopically.
- Moderate to severe synovitis was present in all shoulders; lesions showed patchy, incomplete cartilage infilling even up to 8.9 years post-op.
- Kinetic gait analysis showed no significant differences in PVF/VI between affected and unaffected limbs, despite mild lameness clinically.
- Owners reported good to very good mobility (median LOAD = 6), often underestimating clinical lameness.
- CT detected larger lesion dimensions than radiographs (wider, deeper defects).
- Despite progression of OA, surgical debridement was associated with satisfactory long-term function, though not prevention of degenerative changes.

In Katz 2022 et al., on meniscal flounce sign, what was the sensitivity of the flounce sign for identifying normal menisci?
🔍 Key Findings
- A positive meniscal flounce sign was associated with normal menisci in 95.5% of cases, demonstrating strong predictive value.
- Absence of the meniscal flounce sign was associated with meniscal tears in 92.7% of cases.
- Overall diagnostic accuracy of the flounce sign was 94.6%, with 96.6% sensitivity and 90.5% specificity.
- Most tears in flounce-negative stifles were bucket-handle tears (73.8%), while radial tears were present in some flounce-positive stifles.
- Radial tears did not consistently eliminate the flounce sign, suggesting they may not disrupt meniscal fiber tension sufficiently.
- All procedures were arthroscopically performed, with probing and visualization of the medial meniscus' caudal pole.
- Flounce sign should complement, not replace, probing—especially as some tear types (e.g., radial) may not abolish the sign.
- Limb positioning and joint distraction may affect flounce visibility, introducing minor observer variability.

In Butare-Smith 2022 et al., on cerclage knot biomechanics, which knot type demonstrated the highest resistance to cyclic loading before loosening?
🔍 Key Findings
- Double-loop cerclage resisted the highest peak load (805 N) and maintained tension longer than twist (488 N) and single-loop (397 N) configurations.
- Double-loop cerclage sustained 500,000 cycles at 60–80% of peak load in some cases without loosening, outperforming other types.
- Twist knots loosened rapidly, often within 10 cycles even at low loads (100–390 N).
- Single-loop knots performed better than twist, with partial resistance up to 100,000 cycles at 160 N, but showed wide variability.
- All loosening occurred before wire breakage, indicating clinical failure would happen from slack, not fracture.
- Double-loop cerclage had highest initial tension (323 N) compared to single-loop (124 N) and twist (69 N).
- Fatigue limit was not identified for twist, since they all loosened early at even 20% of peak load.
- Clinical recommendation: double-loop cerclage is best for resisting repeated subfailure loading, ideal for fissure prevention or fragment stabilization.

In Caldeira 2025 et al., on femoral neck fixation, what complication was more likely with the three-screw construct?
🔍 Key Findings
Design: In vitro study on cadaveric femurs (n=21) with basilar femoral neck fractures stabilized using 2 vs 3 titanium cannulated screws.
Stiffness: Control > 3-screw > 2-screw (674 > 120 > 90 N/mm).
Yield Load: 3-screw (586 N) > 2-screw (303 N); both < intact femur (2692 N).
Displacement: No difference across groups.
Complication: 3-screw technique more demanding; higher risk of cortical perforation, especially with narrow femoral necks.
Failure Mode: Dislodgement of femoral head + screw shaft bending.
Conclusion: 3 screws = stronger construct than 2 screws. Clinical implications need further study.

In Sandoval 2024 et al., on lung lobectomy technique outcomes, how many lobectomies per group are needed for a superiority study comparing SLL and stapler?
🔍 Key Findings
- Intra- and postoperative complications occurred only in stapled lobectomies, but the difference was not statistically significant (intra: p = .069, post: p = .112).
- Intraoperative hemorrhage was the most common complication (11.8%), followed by air leakage (2%).
- All self-ligating loop (SLL) lobectomies had zero complications (n=18), though the sample was small.
- Postoperative complications included 4 catastrophic events (cardiopulmonary arrest), all in stapled cases.
- Lung lobectomy technique was not associated with duration of chest tube use, hospitalization, or survival (p > .05).
- 94.3% of patients survived to discharge (82/87).
- SLLs are lower-cost and may be more feasible for thoracoscopic/minimally invasive approaches due to smaller port size (5mm vs. 12mm for staplers).
- A future superiority study would need ≥103 lobectomies per group to assess differences in complication rates.

In Hawker 2024 et al., on checklist attitudes, which group was most often reported as noncompliant with SSC use?
🔍 Key Findings
- 67.9% of respondents reported using SSCs, with most indicating frequent use (64% used in every surgery).
- 78.7% agreed SSCs reduce complications, and 89.6% believed SSCs improve communication.
- Respondents not using SSCs were more likely to view them as a waste of time (p < .001).
- Forgetfulness (39.6%) and time constraints (36.5%) were leading reasons for checklist noncompletion.
- Only 23.3% had SSC training during surgical residency, with newer diplomates more likely to have had exposure (p < .001).
- Key strategies to improve uptake included: staff feedback modifications (67.9%), formal designation of initiator (48.6%), and training (52.2%).
- Surgeons and OR staff were most commonly identified as noncompliant team members.
- SSC use was more frequent in small animal practices, and mandating SSCs by management was favored but not always effective alone.

In Ritson 2025 et al., on feline hilar lobectomy sealants, what **pressure level** was used as the endpoint for leak testing?
🔍 Key Findings
- No leakage occurred using pretied ligature loops (PLL) or double-shank (DS) titanium clips up to 40 cm H₂O airway pressure.
- 1/10 stapled lobes leaked at supraphysiologic pressure (40 cm H₂O), but this was not statistically significant (p = .33).
- All techniques sealed effectively under physiologic and supraphysiologic pressures in cadaveric feline lungs.
- PLL and DS clips required less working space than staplers, making them more practical for small thoracic cavities.
- DS titanium clips offer enhanced security due to dual shanks and tissue-gripping design, reducing clip slippage.
- Leak testing was cyclic and submerged, simulating physiologic ventilation and allowing robust evaluation.
- Stapling failure occurred along the staple line, highlighting risks of air leakage due to staple misalignment or poor hilar access.
- PLL and DS clips may be cost-effective and efficient alternatives for open or minimally invasive feline lung lobectomy.

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 Muroi 2024 et al., on radius plate stress effects, what FEA result was consistent in both LP 1 mm and 3 mm groups?
🔍 Key Findings Summary
- Finite element analysis compared intact radii vs. locking plates placed 1 mm or 3 mm above the bone
- LP placement significantly reduced tensile (maximum principal) stress on cranial cortex, potentially causing implant-induced osteoporosis
- Shell element findings:
- Max principal stress significantly lower in both LP groups vs. intact (p < 0.05)
- Solid element findings:
- Equivalent stress higher and max principal stress lower in LP groups
- Implication: Tension reduction may impair bone remodeling; implant design and placement height affect stress environment

- Bone healing achieved in a median of 8 weeks (range: 4–14 weeks).
- No major complications; minor issues included 1 screw loosening and 1 superficial infection.
- Subjective function was graded full in 4 dogs, acceptable in 7.
- Arthroscopy enabled accurate dynamic joint assessment, preferred over static radiographs.
- Use of both orthopedic wire and plating provided secure fixation and improved outcomes.
