In Muroi 2024 et al., on radius plate stress effects, how did the 1 mm and 3 mm elevated locking plate groups differ in equivalent stress versus intact controls?
🔍 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

In Guevara 2024 et al., on implant placement accuracy, what was the rate of acceptable pin placement using 3D-printed guides?
🔍 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 Scharpf 2024 et al., on arthroscopic MCD treatment, which ground reaction force parameter did **not** normalize by 26 weeks?
🔍 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 Jones 2024 et al., on elbow OA cysts, which joints were most commonly affected by SBCs?
🔍 Key Findings Summary

- Locations: 62% humerus, 28% ulna, 10% radius
- Sex and Age Effects:
- Older dogs had larger SBCs (p = .013)
- Female dogs had smaller SBCs (p = .002)
- SBC number unrelated to age or sex

In Klever 2024 et al., what degree of cranial–caudal pelvic tilt was required before observers consistently perceived images as "tilted"?
🔍 Key Findings
- Dorsoventral radiographs artificially increase Norberg angle values by 3.2–5.8% and should be excluded.
- Lateral pelvic tilt >2° causes asymmetric changes in Norberg angle; >3° results in significant side-specific changes.
- Cranioventral-to-caudodorsal tilt >10° results in obvious radiographic tilt, but changes Norberg angle by only ~2%.
- Tilted but subjectively acceptable images have minor impact and may still be usable for screening.
- Norberg angle readings differed consistently between left/right hips — possibly due to operator handedness.

In Welsh 2025 et al., on orthogonal plating, what was the failure load for the OP2.0 construct?
🔍 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 Vandekerckhove 2024 et al., what force was required for 90% of hips to reach at least 90% of LImax?
🔍 Key Findings Summary
- Used VMBDmD to quantify hip laxity under increasing force in cadaveric dogs (n=34).
- 90% of hips reached ≥90% of LImax at 95.32 N, defining this force as sufficient for subluxation.
- LImax was not significantly influenced by osteoarthritis, weight, sex, or limb side.
- Position of device (lever length) influenced rate of laxity acquisition, not final LImax.
- LI curves were repeatable across 5 sessions, indicating elastic—not plastic—deformation.

- fPLI and A1C were unchanged
- Resection details:
- Mean weight: 3.0 ± 1.4 g
- Mean surgical time: 59.7 ± 16.2 min
- Follow-up: 250–446 days — all cats remained clinically healthy
- Conclusion: Ultrasonic LPP is safe and effective in healthy cats, preserving endocrine/exocrine function

In McLean 2024 et al., which variables were found to have no significant association with rock-back?
🔍 Key Findings Summary
- 95 TPLO procedures reviewed retrospectively with follow-up radiographs
- Rock-back defined as increase in tibial plateau angle (TPA) ≥2° from immediate post-op to recheck
- 21% of stifles (20/95) experienced rock-back
- Mean ΔTPA among rock-back cases = 3.2° ± 2.6°
- No implant failures or tibial tuberosity fractures were reported in these cases
- Plate inclination and exit cut angle (ECA) were not associated with increased risk of rock-back (p = 0.4 and 0.2)
- Authors hypothesize that compression across osteotomy in vivo may mitigate torsional effects from ECA, unlike in gap-model studies
- Emphasizes that rock-back is relatively common, even with well-placed implants

In Holman 2024 et al., on shoulder arthroscopy, what proportion of the biceps tendon was visible arthroscopically with the shoulder in flexion?
🔍 Key Findings
- 48% of the intra-articular biceps tendon was visible at a standing angle; this increased to 63% in flexion (p = 0.0003).
- 58% of the medial glenohumeral ligament's cranial border was within view.
- 20% of the subscapularis tendon was visualized via the standard lateral arthroscopic approach.
- Visibility was assessed using tattoo ink markers and confirmed via dissection in cadavers.
- Limitations of standard lateral portals may lead to underdiagnosis of deeper or distal pathology in these structures.
