In Scharpf 2024 et al., what symmetry index (SI) threshold was considered indicative of normal limb loading?
🔍 Key Findings Summary
- Subtotal coronoidectomy improved vertical and propulsive forces, but braking forces remained subnormal at 26 weeks.
- No significant benefit was seen from ACP vs placebo at any timepoint across all force parameters or lameness scores.
- Force plate analysis was more sensitive than visual lameness scoring.
- Braking force (%FY+) was best at detecting persistent lameness, and SI < 0.9 persisted in most dogs at 26 weeks.
- Outcome less favorable than historically reported — challenges status of subtotal coronoidectomy as “gold standard” for MCD.

In Sisk 2024 et al., what is a theoretical advantage of expandable intramedullary nails?
🔍 Key Findings Summary
- IMN provides relative stability, resists bending/torsion due to central axis alignment
- Larger diameter nails = exponentially greater stiffness (∝ D⁴)
- Trade-off: Larger interlocking holes weaken fatigue strength of the nail
- Reaming increases contact/stability but has pros/cons:
- Improves outcomes in closed fractures
- May reduce endosteal blood flow in thin-walled bones (e.g., cats)
- Design advances:
- Angle-stable IMN reduce rotational slack
- Expandable nails simplify insertion but may compromise removal or compressive load resistance
- Precontoured nails match bone curvature but lack consistent clinical superiority
- Material debates continue (e.g., titanium vs. stainless steel vs. magnesium)

In Thomsen 2024 et al., on CT accuracy for liver tumors, which liver lobes showed significantly lower CT localization accuracy?
🔍 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 Pfund 2025 et al., on femoral cortical thickness, what was the mean CTI for dogs that developed perioperative fractures?
🔍 Key Findings
- Lower CTI values were significantly associated with higher risk of both intraoperative and postoperative femoral fractures or fissures (p <.0001).
- The mean CTI for all dogs was 0.285, whereas dogs with fissures/fractures had a mean CTI of 0.246.
- For each 0.001 increase in CTI, odds of fissure/fracture decreased by 2–3% depending on perioperative timing.
- High interobserver reliability (ICC = 0.984) and consistency between pre- and postoperative CTI measurements (ICC = 0.96).
- CTI was the only significant risk factor identified; age, breed, bodyweight, BCS, CFI, or luxoid hips were not significant.
- Prophylactic lateral plating in dogs with low CTI (mean 0.230) resulted in no postoperative fractures.
- Postoperative fractures occurred in 8% of cases, and 93% of dogs returned to full function within one year.
- CTI may be a useful radiographic screening tool, especially when advanced imaging (e.g., DEXA) is unavailable.

In Miller 2024 et al., on SOP-LC mechanical testing, how did single-side clamp placement affect bending strength compared to alternating sides?
🔍 Key Findings Summary
- No significant difference in mechanical properties between contoured vs non-contoured SOP-LC rods
- Clamp configuration significantly influenced mechanical performance:
- Single-side clamps → ↑ yield load, ↑ displacement, ↑ bending strength (p < 0.05)
- Alternating-side clamps → ↑ initial torsional stiffness (p = 0.029)
- Clamp slippage was evident only in torsional tests; screw loosening may be torque-dependent
- Mild screw bending and construct offset suggest subtle instability
- Recommends clamp configuration choice based on loading scenario
- Suggests 3.0 Nm torque may be more effective than 2.5 Nm to prevent clamp slippage

In Matz 2022 et al., on stapler size comparison, which stapler group had the highest mean initial leak pressure (ILP)?
🔍 Key Findings
- No significant difference in initial leak pressure (ILP) among TA 30 V3 2.5 mm, TA 60 3.5 mm, and TA 60 4.8 mm stapler sizes (P = .78).
- All stapler types exceeded the physiological intraluminal pressure threshold (~25 mmHg), suggesting acceptable leak resistance.
- Mean ILPs: TA 30 V3 (181.5 mmHg), TA 60 3.5 mm (112 mmHg), TA 60 4.8 mm (77.2 mmHg).
- Leakage occurred at the staple line in 23 of 24 specimens; only one had ileal wall rupture.
- No correlation found between ILP and cadaver weight, cecal wall thickness, or cecal length.
- Cecal wall thickness averaged 4.9 mm, yet staple heights ranged only from 1.0–2.0 mm.
- One specimen in each TA 60 group leaked near or below physiologic pressures, suggesting rare outliers.
- Study supports clinical viability of all tested stapler sizes for canine typhlectomy, but highlights need for in vivo data on healing and complications.

In Fracka 2025 et al., on cementless knee replacement, what postoperative improvement in stifle range of motion (ROM) was documented?
🔍 Key Findings
Subject: 7-year-old Labrador underwent cementless total knee replacement (TKR) due to severe stifle OA.

- Improved ROM from 90° pre-op to 120° post-op.
- Weight-bearing increased from toe-touching to 70% bodyweight by 6 weeks post-op.
- No visible lameness by 14 weeks.

Histologic findings:
- Robust osseointegration at implant-bone interface.
- Fibrous tissue only in areas lacking porous coating.
Conclusion:
- Cementless TKR demonstrated excellent 6-year survival and functional outcomes.
- Support for considering early surgical intervention in severe stifle OA.

In Guevara 2024 et al., on implant placement accuracy, what was considered an acceptable placement grade using the modified Zdichavsky classification?
🔍 Key Findings:
- Sample: 24 canine cadavers, 477 total pins across 240 vertebrae.
- Technique Comparison: 3D printed guides (3DPG) vs freehand (FH).
- Acceptable Placement Rates: 3DPG = 87.5%, FH = 69.8% (p < .0001).
- Odds Ratio for FH: 0.28 (95% CI 0.16–0.47), significantly less likely to yield acceptable placement.
- Worst Accuracy Locations: T10 (OR 0.10), T11 (OR 0.35).
- Surgeon Impact: Surgeon 2 outperformed others (OR 9.61, p = .001).
- Modified Zdichavsky Classification used to score implant accuracy (Grades I–IIIb).
- Primary Benefit of 3DPG: Increased safety and precision, regardless of surgeon experience.

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.
