In Gutbrod 2024 et al., on feline tibial stabilization, what intramedullary pin diameter was associated with the highest biomechanical performance?
🔍 Key Findings
- 2.4 mm LCP with a 1.6 mm IM pin had the highest axial stiffness and yield strength among the tested constructs.
- Axial stiffness was significantly higher in the 2.4 mm LCP + 1.6 mm IM pin group compared to 2.7 mm LCP alone (p = .013).
- No significant difference in torsional stiffness was found among groups.
- 2.4 mm LCP + 1.0 mm pin had the lowest stiffness and failure load, underperforming both other constructs.
- All constructs failed via valgus bending, consistent with clinical observations in feline tibial fractures.
- A 1.6 mm pin (~50% canal fill) resulted in superior construct performance vs. 1.0 mm (~30% fill).
- Group 2 (2.4 LCP + 1.6 mm pin) outperformed the 2.7 mm LCP alone in stiffness, despite using a smaller plate.
- Plate–rod constructs may better preserve periosteal blood supply and support minimally invasive stabilization strategies.

In Lin 2025 et al., on surgical approaches to the radius, which approach provided significantly more surface exposure?
🔍 Key Findings
- Craniolateral approach (CLA) exposed significantly more radial surface area than craniomedial approach (CMA) (19.4 cm² vs. 13.8 cm²; p = 0.01).
- Proximal width of exposure was greater in CLA, especially at 12.5% length (P2 level, p = 0.016), aiding plate placement.
- No significant difference in exposed bone length between approaches.
- CLA avoided major neurovascular structures, making dissection cleaner and safer proximally.
- CMA consistently encountered median nerve/artery/vein, complicating proximal exposure.
- CLA allowed better access to proximal radius for locking plate application, which may benefit MIPO techniques.
- CLA also enables ulna fixation via the same incision, whereas CMA requires a separate skin incision.
- Anatomical tilt of the proximal cranial surface favored CLA, requiring less plate contouring than CMA for proper fit.

In Raleigh 2022 et al., on pericardiectomy complications, what was the most common intraoperative outcome for dogs that developed VF?
🔍 Key Findings
- Ventricular fibrillation (VF) occurred in 3% of pericardiectomy cases across reporting institutions.
- 14 of 16 dogs (88%) that developed intraoperative VF died, indicating high mortality.
- Electrosurgical devices were used in 15/16 dogs; VF onset coincided with their use in 8 dogs, suggesting a potential but unproven association.
- Preoperative arrhythmias were seen in 7 dogs (e.g., VPCs, VT, bradycardia), possibly serving as early warning signs.
- Thoracoscopic approach was used in 75% of cases; however, conversion to open surgery was required in 9/13 thoracoscopic procedures after VF onset.
- Defibrillation was attempted in 13 dogs, but only 3 converted to sinus rhythm, and only 2 survived postoperatively.
- VF may result from stray current or cardiac manipulation; bipolar energy devices were implicated despite lower theoretical risk.
- Preventative strategies include judicious electrosurgery use, close ECG monitoring, rapid CPR preparedness, and preop cardiac risk assessment.

In Schuenemann 2025 et al., on biceps tenodesis, what was the anchor type used in all cases?
🔍 Key Findings
- Case series of 6 shoulders in 5 working/sporting dogs. Conditions treated: 3 partial biceps ruptures, 3 luxations with fraying.
- All treated with biceps tenodesis using a bioabsorbable anchor (Weldix 2.3 mm).
- All dogs returned to function (some to high-level sports); lameness resolved within 1–5 weeks.
- No implant-related complications with anchor-only cases. One dog had seroma and later infection but recovered.
- Tendon clamp (used in 2 cases) caused irritation in one dog → resolved after removal.
- CT follow-up confirmed integrity; drill holes filled with bone.
- Median LOAD score: 12; higher in older dogs or with concurrent conditions.
- Authors suggest tenodesis offers more stability and faster return to function than tenotomy in working dogs.
- Larger, controlled studies are recommended.

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 Tobias 2025 et al., on frontal sinus mucoceles, what was a common minor postoperative complication seen in some 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 Shetler 2022 et al., on radial head OCD, what confirmed the diagnosis of osteochondritis dissecans in this case?
🔍 Key Findings
- Bilateral radial head OCD lesions were identified in a 6-month-old English Bulldog with elbow lameness.
- Medial arthroscopic portals allowed only partial visualization of radial head lesions, insufficient for treatment.
- Lateral arthroscopy portals provided excellent access for fragment removal and abrasion arthroplasty.
- Histopathology confirmed OCD, showing cartilage degeneration and retained cartilaginous cores.
- Dog showed complete resolution of lameness and no elbow pain at 5 months post-op.
- Lesions were caudolateral on the radial head, with discoid elevation of cartilage and clefts.
- Lateral approach avoids major neurovascular structures, reducing iatrogenic risk.
- The authors suggest lateral elbow arthroscopy may have broader indications, including for medial compartment disease or synovial biopsies.

🔍 Key Findings
- Modified prepubic urethrostomy (mPPU) was effective for managing proximal urethral obstructions in male cats.
- All 8 cats regained voluntary urination within 24 hours postoperatively.
- Early urinary incontinence and peristomal dermatitis occurred in all cats but were self-limiting.
- Two cats (25%) required surgical revision due to stomal obstruction from weight gain and abdominal fat.
- No intraoperative complications were reported in any of the 8 cats.
- Follow-up (13–84 months) showed sustained urinary continence and owner satisfaction in all cases.
- The rectus abdominis muscle tunnel likely increased outflow resistance, minimizing persistent incontinence.
- Recurrent hematuria and dysuria occurred in 3 cats but were managed conservatively.

In Marturello 2023 et al., on 3D-printed humeral models, what clinical application is most **justified by this study’s findings**?
🔍 Key Findings
- 3D-printed models using desktop printers (FDM, LFS) showed submillimetric accuracy, comparable to or better than industrial-grade PJP printers.
- Bone size had a greater effect on print accuracy than printer type, especially in proximal humerus regions.
- The humeral condyle region showed the greatest model accuracy, with mean differences under 0.5 mm, regardless of printer.
- Models tended to be slightly smaller than cadaveric bones, potentially due to systematic underestimation during printing.
- FDM printer provided the highest accuracy at the humeral condyle in medium-sized bones (+0.09 mm).
- LFS printer produced prints faster and more reliably than FDM, although both had comparable dimensional accuracy.
- Statistically significant differences existed, but all were submillimetric and unlikely to impact surgical outcomes.
- Desktop printers are suitable for surgical planning, including plate pre-contouring and patient-specific instrumentation.
