In Low 2025 et al., on machine-learning outcomes in IVDE, which model achieved the highest predictive performance for ambulation recovery?
🔍 Key Findings
The study included 162 deep-pain-negative dogs undergoing decompressive surgery (hemilaminectomy) for acute thoracolumbar intervertebral disc extrusion (IVDE).
Ambulatory recovery occurred in 53.1% of dogs (86/162).
The best performing machine-learning model was XGBoost, with an AUC of 0.9502 and accuracy of 89.1%, outperforming Ridge, AdaBoost, and Naive Bayes models.
Preoperative-only XGBoost models were less accurate, with AUC dropping to 0.8271 and accuracy to 71.9%.
Top predictive features (by SHAP analysis) included:
- T2-weighted to L2 spinal cord signal ratio (lower values predicted better outcome)
- Use of fenestration (presence associated with better recovery)
- Hospitalization duration
- Imaging modality used
- Duration of nonambulatory status
Machine learning provided better insight into prognostic factors than traditional statistical methods.

In Danielski 2022 et al., on humero-anconeal incongruity, what dynamic sign was frequently observed during elbow manipulation in dogs with HIF?
🔍 Key Findings
- A novel caudo-medial arthroscopic portal allowed visualization of previously undescribed cartilage lesions on the caudal medial humeral condyle.
- A consistent focal cartilage lesion (HA lesion) was observed in 100% of elbows with HIF (21/21), but in none of the 31 elbows without HIF.
- Lesions varied from indentations to full-thickness cartilage loss, typically elliptical and located just medial to the humeral condyle isthmus.
- A clunk-like sensation and dynamic engagement of the anconeal process into the lesion were observed in 16/21 elbows with HIF during elbow manipulation.
- In 5/21 elbows, engagement of the anconeal process led to observable widening of the HIF line, suggesting dynamic instability.
- Findings support a novel concept of humero-anconeal incongruity as a contributor to the pathogenesis of HIF.
- Spaniel breed was not a confounder—the lesion was only present in elbows with HIF, regardless of breed.
- The study suggests potential for using arthroscopy as a screening tool for early detection of humero-anconeal incongruity and HIF risk.

In Clough 2022 et al., on CBLO-TTT construct testing, what is the clinical implication of combining CBLO and TTT?
🔍 Key Findings
- Combined CBLO-TTT did not reduce load to failure compared to CBLO or TTT alone (P = .81 and P = .12, respectively).
- CBLO-TTT maintains construct strength without significant compromise compared to individual procedures.
- Most common failure mode in CBLO-TTT was displacement of the tibial crest segment with k-wire pullout and tension band untwisting.
- No fulcrum effect was seen in CBLO-TTT, unlike TPLO-TTT combinations, likely due to preservation of buttress effect.
- Patellar ligament avulsion occurred in both CBLO and CBLO-TTT, but not as a clinical concern — possibly artifact from cadaver model.
- Load-to-failure testing was static and unidirectional, not accounting for cyclic fatigue or in vivo healing.
- Plate size and saw blade variation were based on clinical realism, introducing potential variability but not affecting outcomes.
- Study suggests feasibility of simultaneous surgical correction of CCL rupture and MPL using CBLO-TTT in dogs.

In Israel 2022 et al., on cerclage wire in THR, what was the reported incidence of proximal femoral fractures in dogs with cerclage placement?
🔍 Key Findings
- No proximal femoral fractures occurred in any of the 184 hips with cerclage wire placement
- Cerclage wire was well tolerated, with no failures or complications related to the wire
- Application of a single cerclage wire took <10 minutes, was cost-effective, and required minimal instrumentation
- 3 postoperative complications (1 fissure, 2 fractures) occurred distal to the cerclage site, near the stem tip, requiring plate/screw fixation
- All dogs returned to normal activity, and all owners were satisfied with the outcome
- Cerclage placement location is critical—must be proximal to the lesser trochanter and close to the calcar to resist hoop strain
- Biomechanical evidence supports that cerclage wires improve resistance to hoop strain and subsidence of cementless stems
- Press-fit cementless stems may settle, but when supported by cerclage, this does not result in fractures even in undersized implants

In Thomsen 2024 et al., on CT accuracy for liver tumors, CT accuracy was NOT significantly influenced by which of the following?
🔍 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 Healy 2025 et al., on incidental PBBs, what was the prevalence of PBBs in the studied dog population?
🔍 Key Findings
Population: 2,178 canine CTs reviewed retrospectively.
Prevalence: Incidental PBBs found in 1.37% (30/2178).
Outcome: None of the dogs with incidental PBBs developed clinical spontaneous pneumothorax (SP) over a median follow-up of 1255 days.
Significant Associations:
- Age: Dogs with PBBs were significantly older (median 10.5 yrs vs. 8.2 yrs, p = .001).
- CT indication: PBBs more likely during neoplastic staging (p = .006).
PBB Characteristics:
- Total = 60 PBBs (median 1/dog; range 1–7).
- Location: 35% in left caudal, 31.6% right caudal, only 13.3% in right cranial lobe.
- Size-based: 25 bullae (>10 mm), 35 blebs (≤10 mm).
Conclusion: Prophylactic resection of incidental PBBs not justified given no observed SP risk in this population.

In Ellis 2024 et al., what conclusion was drawn regarding sclerosis seen on elbow CT in Guide Dogs?
🔍 Key Findings Summary
- 86 elbows assessed: 32 Guide Dogs, 11 Border Collies
- Guide Dogs showed significantly higher HU values in:
- MCP: min (p = 0.022), mean (p < 0.01), max (p < 0.01)
- Humeral trochlea: mean (p < 0.01), max (p < 0.01)
- Results imply breed-associated HU variation, not necessarily pathologic sclerosis
- Relevance: Important to avoid false positives for elbow dysplasia during CT-based breeding screens
- Good interobserver agreement for mean HU values (ICC ~0.82–0.90)

In Wood 2024 et al., on knot security and locking throws, what was the effect of a single locking throw on holding strength?
🔍 Key Findings
- Adding a single locking throw significantly increased holding security for specific knots, including the surgeon's throw (p = .0001) and square throw (p = .0002).
- For the Miller's throw (p = .166) and strangle throw (p = .808), no significant improvement was observed with a locking throw.
- After locking throw addition, all five knots leaked at similar pressures (p = .5233), and these pressures exceeded physiologic arterial pressures.
- Surgeon's throw without a locking throw had the lowest leak pressure (62.5 ± 46.2 mm Hg), below physiologic arterial values.
- The square throw without locking also leaked below physiologic pressures (148.7 ± 109.4 mm Hg), though it outperformed the surgeon's throw.
- Miller’s and strangle throws performed significantly better than square or surgeon’s throws without locking, achieving leak pressures >200 mm Hg.
- All knots used 2-0 polyglyconate monofilament (Maxon); no comparisons across suture types or sizes were performed.
- Authors concluded that correct tensioning and locking throw addition are key to safe vascular ligation. Miller’s, strangle, or slip knots are preferred for challenging surgical fields.
