In Berger 2023 et al., on elbow COR estimation, what was the most common exit location of axes in *normal* elbows on the lateral cortex?
🔍 Key Findings
- COR of elbows with FMCP was significantly more caudal compared to normal elbows, based on CT-derived geometry.
- In normal elbows, 74% of medial and 93% of lateral axes exited cranial and distal to the epicondyles.
- In FMCP elbows, 81% of medial and 70% of lateral axes exited caudal and distal to the epicondyles.
- Different landmark combinations produced slightly different COR approximations, especially between humeral vs. radius/ulna-based axes.
- The medial-lateral axis using trochlea and capitulum centers provided the most consistent COR approximation.
- COR estimations based on diseased elbows may not match normal joint geometry, impacting implant alignment accuracy.
- External epicondylar landmarks may be useful intraoperatively to estimate COR location, but variability limits precision.
- Drill diameter size may buffer small COR differences, but impact in advanced disease or bilateral cases remains unclear.

In Saitoh 2025 et al., on CTS stabilization, which of the following was used in the majority of stabilization procedures?
🔍 Key Findings
Study population: 12 dogs with medial or lateral tarsocrural joint instability (TCI), including 5 working farm dogs.
Procedure: Temporary immobilization using a calcaneotibial screw (CTS) combined with external coaptation (EC).
Stabilization techniques:
- 3 dogs = primary ligamentous repair
- 8 dogs = synthetic ligament reconstruction
- 2 dogs = malleolar fracture repair
Follow-up: Median 31 months (range 4–66); 10 owners completed outcome survey.
Outcomes:
- All 10 dogs had improved or resolved lameness.
- All 5 farm dogs returned to work (most at full or substantial capacity).
- Complication rate: 4 distinct events in 3 dogs (1 major = CTS breakage; 3 minor = bandage-related soft tissue injuries).
Conclusion: CTS + EC provided effective immobilization with low complication rate, and functional outcomes were favorable even in active dogs.

In İnal 2025 et al., on feline high-rise trauma, what percentage of cats lacked the classic triad of HRS signs (epistaxis, pneumothorax, hard palate fracture)?
🔍 Key Findings
Sample: 373 cats with high-rise syndrome (HRS) from 2017–2020.
ATTS was the only significant predictor of survival (p < 0.001); each point increase decreased survival odds (OR = 0.46).
AUC for ATTS ROC curve: 0.857 (95% CI: 0.788–0.926).
Floor height, lesion type, and ground surface were not significantly associated with survival.
Odds of injury were 7.98× higher when landing on hard vs. soft surface (p < 0.001).
16.96× increased injury risk from the fourth vs. third floor (p = 0.008).
Cats with ATTS ≥7 had 62% mortality; median ATTS increased with floor height (r = 0.244, p < 0.001).
Thoracic and vertebral trauma were most common causes of death.
Only 32% of cats had the “classic” HRS triad (pneumothorax, epistaxis, hard palate fracture).

🔍 Key Findings
Study size: 105 dogs (73 ORPS; 32 MIPO)
MIPO vs ORPS differences:
- Surgical time: MIPO median 130 min vs ORPS 85 min (p < .001)
- Explant rate: MIPO 25% vs ORPS 4.1% (p = .003)

- Comminution more frequent in MIPO (41% vs 16%; p = .012)
Significant predictors for MIPO use: More proximal fracture margin (p = .004), surgeon identity (p < .001)
No significant difference: Sagittal alignment, radial length, union rate, or complication rate by surgeon
Implant preference: Fixin plates used in 84% of MIPO; locking plates more common in ORPS

In Thomsen 2024 et al., on CT accuracy for liver tumors, which anatomical level had the highest 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

- Mean surgical time: 59.7 ± 16.2 min
- Follow-up: 250–446 days — all cats remained clinically healthy

In Aldrich 2023 et al., on liposomal bupivacaine in TPLO, what was the reported correlation between CMPS-SF scores and %BWdist?
🔍 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 Hawker 2025 et al., on locking head inserts, what was the impact of LHI on plate strain in a fracture-gap model?
🔍 Key Findings
- Adding Locking Head Inserts (LHI) to a 3.5-mm LCP had no effect on plate strain, stiffness, or deformation in an open fracture gap model.
- Peak strain consistently occurred at the Combi-hole over the fracture gap, with values up to ~1837 µε.
- No significant difference in strain was found across configurations with 0, 3, or 9 LHI (p = 0.847).
- Construct stiffness and compressive displacement also remained unchanged regardless of LHI count (p = 0.311 and 0.069 respectively).
- Study contradicted the hypothesis that LHI would reduce strain and increase stiffness under biologic loading.
- Combi-hole design may limit the efficacy of LHI, as LHI only fill the locking portion, not the compression side where strain peaks.
- Implant fatigue risk remains highest over unfilled screw holes, especially over fracture sites—confirming previous failure patterns.
- Surgeons should consider alternative methods to reduce strain when facing high implant load scenarios.

In Miller 2025 et al., on spinal drill guide accuracy, what was the Zdichavski classification for all screw placements?
🔍 Key Findings
- 3D-printed, SOP plate-specific guides enabled safe screw placement from T12–L5 in canine cadavers and models.
- All 140 screw trajectories were classified as Zdichavski Grade 1, indicating optimal placement without vertebral canal breach.
- Screw angles (cranial-caudal and transverse) matched preoperative planning, with no significant deviation.
- Entry/exit point deviations were <1 mm on average, deemed clinically negligible.
- Drill guides were quick to place (<30 sec per vertebra) and improved ease of surgery.
- Plates acted as effective reduction tools, guiding alignment during screw placement in mobile spines.
- Minor technical challenges arose from cadaveric spine mobility, mitigated by sequential screw insertion.
- Technique may enable future use in fracture/luxation reduction, pending further cadaveric and clinical trials.

In Kalmukov 2022 et al., on cell salvage efficacy, which statement is TRUE regarding post-salvage PCV values?
🔍 Key Findings
- Direct suction salvaged more red blood cell mass (rbcM) than swab washing: 88.43% vs 84.74% (p = .015)
- Swab washing still achieved high recovery (84.74%), making it a viable adjunct when suction is not possible
- No significant difference in post-salvage PCV between methods (~34% for Su and ~33.9% for Sw)
- Total salvaged blood volume was significantly higher using direct suction (143 mL vs 139.8 mL; p < .001)
- Leukocytes are removed during salvage, potentially lowering risk of cytokine-mediated transfusion reactions
- Expired pRBCs were used, but device still achieved high RBC recovery, supporting clinical utility
- Swab washing via manual agitation may cause more RBC destruction than direct suction
- Cell salvage may avoid complications of allogeneic transfusions, like storage lesions and immunologic reactions
