In Neal 2023 et al., on transcondylar screw placement, which variable significantly influenced screw trajectory deviation regardless of method used?
🔍 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 Cola 2024 et al., on laparotomy-assisted endoscopy, which of the following foreign body characteristics significantly affected the success of LAER?
🔍 Key Findings
- LAER was effective (partial or complete) in 35/40 cases, regardless of FB location or type.
- Intestinal wall damage significantly increased the likelihood of conversion to enterotomy (p = .043).
- LAER led to significantly shorter hospitalization (median 48 h vs 72 h; p = .006).
- Patients in the LAER group required less postoperative analgesia (median 36 h vs 48 h; p < .001).
- Faster return to spontaneous feeding was seen in LAER group (median 24 h vs 36 h; p = .012).
- No significant difference in complication rate or postoperative ileus between LAER and enterotomy groups.
- Sharp, linear, or multiple FBs did not significantly affect LAER effectiveness.
- Conversion to surgery was required in 5/40 LAER attempts, mostly due to immovable FBs or intestinal damage.

In Ritson 2025 et al., on feline hilar lobectomy sealants, how were devices evaluated for seal integrity?
🔍 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 Burton 2025 et al., on antebrachial conformation, what statistical result supported intraobserver reliability of PRUDA and UCORA?
🔍 Key Findings
- PRUDA (proximal radio-ulnar divergence angle) and UCORA (ulnar center of rotation of angulation) were significantly greater in Cocker Spaniels with HIF vs those without.
- PRUDA (p < .001): Group 1 (HIF) vs Group 2 & 3.
- UCORA (p = .036): Group 1 vs Group 3.
- Other angles (MPRA, LDRA, PCRA, DCRA, torsion) showed no significant differences.
- Increased PRUDA and UCORA may lead to divergent load vectors across the humeral condyle, potentially predisposing to stress fracture (HIF).
- Measurement techniques using CT-based 3D reconstructions were reliable (intraobserver ICC > 0.84).

In Nash 2024 et al., on esophageal pH monitoring, what percentage of dogs experienced proximal GER events during the recording period?
🔍 Key Findings
- Esophageal pH-monitoring was well tolerated in all 35 nonbrachycephalic dogs, with no major adverse events reported.
- Distal GER occurred in 80% of dogs, but events were typically brief and non-productive; proximal GER occurred in only 39%.
- Upper reference limits for GER were 2.4 events/hour (distal) and 0.4 events/hour (proximal).
- Cumulative acid exposure was minimal: upper limits were 2.3% (distal) and 0% (proximal).
- Comparison with brachycephalic dogs shows significantly higher GER frequency and duration, validating the diagnostic utility of pH monitoring.
- Transnasal probe placement under light anesthesia was safe and less morbid compared to percutaneous or conscious techniques.
- No expelled or productive regurgitation occurred, despite some GER events, indicating efficient esophageal clearance in healthy dogs.
- Diet and fasting duration may affect GER, but these were not controlled variables in this study.

In Paulick 2022 et al., on feline ilial plating, which of the following statements best describes the failure mode observed in **locking plate constructs**?
🔍 Key Findings
- Locking plates (except ALPS-5) withstood significantly more cycles before failure than nonlocking DCP constructs.
- ALPS-6.5, LCP, and FIXIN plates endured higher loads and resisted displacement better than DCP and ALPS-5.
- ALPS-5 plates showed lower bending stiffness than all other constructs (P < .05).
- DCP constructs failed due to screw loosening, seen in all specimens.
- Locking constructs failed by bone slicing, affecting 100% of specimens.
- Catastrophic implant failure (fracture or plastic deformation) occurred only in ALPS-5 group.
- Plate size and screw-plate interface both influence resistance to cyclic loading in feline ilial fracture repair.
- Locking plates are preferable for reducing screw pullout, but plate strength (e.g., cross-section) must match loading forces.

In Bounds 2023 et al., on feline hip arthroscopy, which statement best describes feasibility of hip arthroscopy in cats with DJD?
🔍 Key Findings
- Feline hip arthroscopy using a supratrochanteric lateral portal was feasible in all cadaveric hips studied.
- All relevant intra-articular structures (femoral head, acetabulum, round ligament, joint capsule, transverse acetabular ligament, dorsal acetabular rim) were consistently visualized.
- Optimal limb positioning (neutral abduction, 90° extension) significantly aided joint distraction and visualization.
- Minor iatrogenic cartilage injury (ICI) occurred in all hips, typically partial-thickness abrasions; one hip had a full-thickness lesion.
- Portal placement did not damage the sciatic nerve or caudal gluteal artery, with a mean distance of 4.3 ± 2 mm between the cannula and nerve.
- Probe use improved visualization of the dorsal joint capsule and dorsal acetabular rim, though not essential.
- Joint evaluation was also successful in hips with DJD, suggesting technique feasibility even in diseased joints.
- Muscle trauma was minimal, with only mild impingement in a few specimens and no gross nerve or vessel injury.
