In Muroi 2024 et al., on radius plate stress effects, what was the yield load measured during mechanical testing of cadaveric radii?
🔍 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 Downey 2023 et al., on thoracoscopic lobectomy, what was the long-term outcome for dogs that survived to discharge?
🔍 Key Findings
- Thoracoscopic (TL) or thoracoscopic-assisted (TAL) lobectomy was successfully performed in 12 dogs with non-neoplastic pulmonary consolidation (PC).
- 44% (4/9) of TL cases were converted to open thoracotomy due to adhesions or poor visualization—higher than rates for neoplastic lobectomies.
- OLV was successful in 7/9 TL dogs; unsuccessful attempts were managed with intermittent ventilation, mostly in brachycephalic breeds.
- Median hospital stay was 3 days; 91.7% (11/12) survived to discharge, and 100% of survivors showed no recurrence at median 24-month follow-up.
- Complications were mostly minor: pneumothorax (2), minor hemorrhage (3), dehiscence (1), and 1 fatality due to BOAS complications.
- Histopathology showed infectious pneumonia in 10 dogs, and in 4 cases, foreign body migration was suspected as the underlying cause.
- Median surgical time for TL was 90 minutes; conversion correlated with longer symptom duration (median 90 vs. 7 days).
- Postoperative recovery was excellent in all surviving dogs, with one case of persistent cough attributed to concurrent heart disease.

In Schneider 2025 et al., on axillary LN extirpation, which statement best reflects the accuracy of cytology for staging ALNs?
🔍 Key Findings
- Lateral approach to ALN extirpation was successful in 100% of cases (44 dogs, 48 ALNs) with consistent anatomical landmarks (costochondral junction of rib 1 and caudal scapular edge).
- Median time for ALN removal was 16.6 minutes, highlighting a fast and efficient dissection method.
- No intraoperative complications were recorded (e.g., hemorrhage or inability to find the lymph node).
- Postoperative complications occurred in 18% of cases, including seromas (n=2), wound dehiscence (n=4), lameness (n=1), and discomfort (n=1).
- Histopathology revealed 56% of ALNs had tumor-related pathology, including overt metastases, early metastasis (HN2), or premetastatic changes (HN1).
- Normal-sized ALNs (<2 cm) still harbored metastases in 22% of cases, emphasizing the unreliability of size as a staging criterion.
- False negatives in cytology occurred in 4 cases, underlining the limitations of cytologic evaluation for staging.
- The technique was reproducible without specialized tools, suggesting wide applicability in general and referral practice.

In Aldrich 2023 et al., on liposomal bupivacaine in TPLO, how was analgesic success defined?
🔍 Key Findings
- Liposomal bupivacaine (LB) infiltration did not reduce the need for rescue analgesia compared with placebo in dogs undergoing TPLO.
- CMPS-SF pain scores were not significantly different between LB and placebo groups at any postoperative time point.
- % body weight distribution (%BWdist) to the operated limb did not differ significantly between treatment groups across all time points.
- No correlation was found between CMPS-SF scores and %BWdist, suggesting these metrics assess different aspects of postoperative pain.
- Postoperative carprofen administration was standardized, and LB did not provide additional detectable analgesic benefit.
- Three-layer infiltration technique (joint capsule, fascia, subcutis) was used consistently across all cases.
- Adverse events were minor and comparable between LB and placebo groups.
- Post hoc analysis suggested a much larger sample size (58–436 dogs) would be needed to detect significant differences in %BWdist.

In Swieton 2025 et al., on portocaval shunts, how many dogs were confirmed to have persistent shunting on imaging follow-up?
🔍 Key Findings
Study population: 21 dogs with portocaval extrahepatic portosystemic shunts (EHPSS)
Surgical approach: 67% (14/21) underwent ameroid constrictor placement
Perioperative complications: 4 dogs (19%), including seizures (n = 2), vomiting, and abdominal effusion
Perioperative mortality: 1 dog (5%)
Postoperative clinical outcome:
- Good to excellent outcome: 81% (17/21)
- Median follow-up: 6 months (range 3–43)
Persistence of shunting (CT or US): 56% (9/16 evaluated)
Dogs with persistent shunting: 67% still had good to excellent clinical outcome
Congenital portocaval shunts may have more favorable outcomes than previously reported

In Meltzer 2022 et al., on femoral implant selection, which factor most consistently predicted the use of a cemented femoral stem?
🔍 Key Findings
- Hybrid implants were used in older, heavier dogs with lower canal flare index (CFI) compared to cementless types.
- CFI <1.8 was associated with higher risk of femoral fracture or stem subsidence with cementless implants.
- Total complication rate was 14%, with catastrophic complications in only 1.5%—lower than reported in other studies.
- No significant difference in complication rates across implant types (BFX, BFX-C, hybrid).
- Femur fractures were rare (2.9%), lower than in prior studies, and successfully managed with cerclage/plate fixation.
- Coxofemoral luxation was the most common complication (8 cases); all occurred within 62 days post-op, mostly resolved with revision.
- Collared BFX stems did not significantly reduce complications, though they may limit stem subsidence.
- An implant selection algorithm was proposed, using age ≥7 years, weight ≥45 kg, and CFI <1.8 to guide cemented vs. cementless stem use.

In Lu 2025 et al., on SOP constructs, what mechanical outcome was observed across **all test constructs**, regardless of tee presence?
🔍 Key Findings
- Bending tees significantly increased mediolateral bending stiffness, but not craniocaudal stiffness, in plate-bone constructs.
- Mean mediolateral stiffness was 43.2 N/mm with tees vs. 41.1 N/mm without (p = 0.0042), though the absolute difference was small.
- No significant differences were found in craniocaudal bending stiffness between constructs with or without tees (p = 0.89).
- Plastic deformation occurred in all constructs; no screw pull-out or implant breakage was observed.
- SOP nodes may resist compressive but not tensile deformation, suggesting variable mechanical contributions depending on loading direction.
- Craniocaudal bending had greater stiffness than mediolateral due to higher area moment of inertia along the node diameter.
- Clinical relevance of added stiffness from tees remains unclear, warranting further in vivo and cyclic testing.
- This was the first study to directly test SOP constructs with/without tees over a fracture gap in multiple planes.
