In Kurogochi 2025 et al., on cardioplegia in mitral repair, what was the effect of mDN solution on sinus rhythm recovery?
🔍 Key Findings
- No significant difference in cardiac troponin I levels 12h post-op between mDN and St. Thomas cardioplegia groups (p = 0.478)
- Sinus rhythm returned faster in the mDN group after aortic cross-clamp removal (median 60s vs 362s, p = 0.027)
- Lower serum potassium at cross-clamp removal in the mDN group (median 4.5 mEq/L vs 5.4, p = 0.005)
- Fewer doses needed in the mDN group (median 2.5 vs 4.0, p = 0.040)
- Higher total crystalloid volume used in mDN group (23.6 vs 12.6 mL/kg, p < 0.001)
- No difference in survival (700-day survival 90% in both groups, p = 0.958)
- No difference in hospitalization duration (median 6 days for both, p = 0.789)
- Echocardiographic remodeling similar between groups at 24h post-op

In Petazzoni 2022 et al., on DPO in older dogs, what was the selection criterion for minimal osteoarthritis?
🔍 Key Findings
- DPO improved joint congruity and clinical signs in dogs ≥10 months old with minimal osteoarthritis.
- Median Norberg angle increased by 21.8% 1 year postoperatively (from 87° to 106°; p < .01).
- Femoral head coverage increased significantly, with PC rising 66.7% and LHC by 162.5% at 1 year (p < .01).
- No significant change in pelvic canal width postoperatively, suggesting pelvic conformation was preserved.
- All ilial osteotomies healed with complete osseous bridging by 8 weeks; 7/11 pubic osteotomies achieved full healing.
- No intraoperative or postoperative complications were reported, including implant failure.
- Locking plates and additional ventral plating were used in select cases and may have contributed to implant stability.
- DPO may be extended to older dogs with suitable hip morphology and minimal OA, expanding traditional age criteria.

In Perez Neto 2025 et al., on hip resurfacing arthroplasty, what was the most common site of failure in both groups?
🔍 Key Findings
- In an ex vivo study of 20 canine femur pairs, implantation of a novel hip resurfacing arthroplasty (HRA) prosthesis reduced maximum load (ML) by 22% and load at collapse (LC) by 27% vs. intact controls (p ≤ 0.05).
- Displacement at maximum load (DML), displacement at collapse (DC), and stiffness (k) were not significantly different between prosthesis and control groups.
- Both groups showed similar failure patterns, with 92% failing at the femoral neck.
- All prosthetic femurs still withstood ~6.2× body weight — exceeding estimated in vivo peak loads (~1.64× BW).
- Prosthesis positioning (neutral vs valgus) had no significant effect on biomechanical outcomes.
- Implant design preserved more metaphyseal bone stock than total hip replacement, possibly explaining the smaller load reduction compared to other short-stem prostheses.
- The press-fit cobalt–chromium design with conical stem allowed full contact and stress distribution over the femoral head/neck.
- Authors conclude the device has adequate immediate biomechanical strength for clinical use, though long-term in vivo studies are needed.

- Fixation method had no significant impact on complication rates (p = 0.87)
- Epicondylar comminution was significantly associated with complications (p = 0.02, OR = 3.27)
- Contralateral intracondylar fissure found in 9.8%, none progressed to fracture during study

In Tobias 2025 et al., on frontal sinus mucoceles, which imaging finding was most consistently reported across all dogs?
🔍 Key Findings
- Frontal sinus mucoceles occurred in young dogs, often linked to prior skull trauma by 10 months of age.
- All dogs presented with expansile, fluid-filled lesions causing facial swelling; CT showed multicentric bone erosion, including the frontal bone and cribriform plate.
- Surgical options included frontal sinusotomy with either sinus lining ablation or re-establishment of nasofrontal drainage, with or without stenting.
- Nasofrontal stenting led to long-term resolution in most dogs, although recurrence occurred in 4/8 dogs, requiring revision surgery in 3.
- Complications were minor and included swelling or nasal discharge; no intraoperative complications were reported.
- Histology confirmed sterile mucoceles with neutrophilic inflammation and mucin, and cultures were negative in all cases.
- Guaifenesin was used postoperatively in several cases to reduce mucus viscosity; its benefit is unproven in dogs but may support drainage.

In Marshall 2022 et al., which **dog-related factor** significantly increased the odds of delayed or non-union?
🔍 Key Findings
- Delayed union occurred in 13.9% of fractures; non-union in 4.6%; mal-union in 0.7%
- Major implant failure increased odds of delayed or non-union by 12.9×
- Surgical site infection increased risk 3.2×; bone grafting (any type) was also associated (OR 3.3)
- Comminuted fractures had 4.2× greater odds of delayed or non-union
- Older age increased risk, with odds increasing by 21% per year
- Radius and ulna fractures in toy breeds were not high risk, contrary to historical belief
- Most non-unions required revision surgery with rhBMP-2 or autograft to achieve union
- Ilium fractures showed 0% delayed/non-union — possibly due to robust muscle envelope

In Price 2024 et al., on left-sided TD ligation in dogs, where were all thoracic duct branches located in cadaveric dissections?
🔍 Key Findings
- Left fourth intercostal thoracotomy allowed successful thoracic duct (TD) ligation in 9/10 canine cadavers.
- 10/13 clinical cases had a single TD branch at the left fourth intercostal space, indicating lower anatomical complexity.
- All TD branches at this site were lateral to the esophagus, simplifying surgical access.
- Unilateral subphrenic pericardiectomy was successfully performed via the same incision in 10/10 cadavers.
- Fewer TD branches at the fourth intercostal space than traditional caudal sites may reduce the risk of missed collaterals.
- In contrast, traditional caudal TD ligation sites had up to 5 branches, requiring broader dissection.
- No cadaver had right-sided TD branches, reducing surgical complexity at the studied location.
- Contrast-confirmed ligation was effective in 90% (9/10) cadavers on CT imaging.

In Kikuchi 2025 et al., on arthroscopic MMI in toy breeds, what was the purpose of using a 2.4-mm arthroscope in this population?
🔍 Key Findings
- Medial meniscus injury (MMI) occurred in 36.3% of stifles with CrCLR in toy breed dogs (<5 kg)
- Complete CrCLR was significantly associated with MMI (15.3% of complete vs. 3.4% of partial)
- Severe lameness (grade 3) increased the likelihood of MMI compared to mild lameness (grade 1)
- Higher body weight, even within the toy breed range, was positively associated with MMI
- Yorkshire Terriers had the highest MMI incidence (55.6%), but this was not a significant independent factor due to multicollinearity
- Arthroscopy identified more meniscal damage (including small radial tears and bucket-handle lesions) than gross examination might detect
- MMI was classified as mild (radial tear) or severe (bucket-handle or flap) with implications for partial meniscectomy
- Arthroscopy was used in all cases, underscoring its utility in small-breed stifle assessment
