In Ramsey 2025 et al., on tibial alignment, what effect did bent interlocking nails have on medullary canal fill?
🔍 Key Findings
- Straight interlocking nails (sILN) resulted in a significantly higher postoperative TPA compared with the contralateral limb (+5°), whereas bent nails (bILN) increased TPA by only +1°.
- Bent interlocking nails achieved closer-to-anatomic tibial plateau alignment than straight nails (p < .0001).
- Both techniques resulted in mild valgus malalignment (~2°) compared with the contralateral limb, but this was not clinically significant.
- No significant differences in medial mechanical proximal tibial angle (mMPTA) were detected between groups.
- Medullary canal fill was higher with bent nails (by ~6.6%), suggesting improved coaxial nail placement.
- Missed bolt hole frequency did not differ between straight and bent nail techniques.
- Complication rates were very low, with only one clinically relevant malalignment reported in the bent nail group.
- Despite higher TPA in the straight nail group, no increased incidence of CCL rupture was identified during follow-up.

In Hoenecke 2025 et al., on radiographic opacity in patella luxation, which variable was found to significantly increase the likelihood of radiographic soft tissue opacity in the stifle?
🔍 Key Findings
- 65% of stifles with patella luxation and intact CCLs had increased radiographic soft tissue opacity
- Weight and radiographic OA were significantly associated with increased opacity (p = .0029 and p = .0143)
- Each 1 kg increase in weight increased the odds of opacity by 10%
- Grade of patella luxation, age, and muscle atrophy were not significantly associated with increased opacity
- 19% of dogs with long-term follow-up developed a CCL rupture post-patella surgery, 50% of those had opacity at initial presentation
- Radiographic opacity alone should not be interpreted as CCL disease in dogs with patella luxation
- Radiographic findings likely represent effusion or synovial hyperplasia, not CCL pathology
- Arthrotomy was used to confirm CCL integrity at surgery, but arthroscopy could provide better sensitivity

In Walker 2022 et al., on TPLO mRUST scoring, which minimum score was associated with a 99% likelihood of subjective union?
🔍 Key Findings
- TPLO mRUST scoring showed improved inter-rater reliability (ICC = 0.56) compared to subjective evaluation (Kappa = 0.33).
- Intra-rater reliability was similar for both methods (TPLO mRUST: 0.73, subjective: 0.72).
- TPLO mRUST scores ≥10/12 strongly correlated with radiographic union, as subjectively assessed (99% agreement).
- No significant difference in healing between first and second TPLO sides (P = .09), countering assumptions about load-bearing impact.
- Higher initial lameness scores and younger age were associated with higher TPLO mRUST scores, suggesting more robust healing in those groups.
- Postoperative complications were linked to lower TPLO mRUST scores, indicating impaired healing.
- Medial cortex was excluded from scoring due to plate obstruction, validating use of only 3 cortices for scoring.
- The TPLO mRUST system may standardize healing assessment, reducing subjective bias across specialties.

🔍 Key Findings:
- Design: Ex vivo study with 24 paired limbs from normal beagle dogs.
- Osteotomy types (3 groups):
- 30° uniplanar frontal wedge
- Oblique (30° frontal, 15° sagittal)
- Single oblique (30° frontal, 15° sagittal, 30° external rotation)
- Comparison: 3D PSG vs Freehand (FH)
- Main Outcomes:
- PSG accuracy: Mean angular deviation = 2.8° vs 6.4° in FH (p < .001).
- 84% of PSG osteotomies were within 5° of target vs 50% of FH.
- Significant improvements with PSG in:
- Group 1 (uniplanar frontal) proximal and distal frontal planes (p < .001, .006)
- Group 3 (SOO) frontal and sagittal planes (p = .002, .043)
- Time: PSG faster in complex SOO group (84s vs 162s, p < .001); no difference in others.
- No difference in osteotomy location (mm) between methods.
- Clinical relevance: PSG more consistent and accurate, especially for complex cuts.

- Functional outcome: 57/60 full function, 2 acceptable, 1 unacceptable
- Complication rate: 3 total (2 minor, 1 major recurrence)
- TRP spares cartilage unlike trochleoplasty, offering implant-based ridge augmentation
- No implant loosening or infection observed

In Nicolas 2024 et al., how was the scapular osteotomy stabilized?
🔍 Key Findings Summary
- The lateral approach via scapular osteotomy allowed safe access to the T1-2 foramen in a French Bulldog with foraminal disc extrusion.
- A mini-hemilaminectomy was performed, preserving articular facets.
- The dog had no neurologic deficits postoperatively, returned to ambulation within 24 hours, and was discharged in 3 days.
- At 10 months, CT confirmed excellent scapular healing and no recurrence.
- Double 2.4-mm locking plates provided stable fixation across the scapular spine.
- The technique avoided thoracic entry or dorsal spine dissection, suggesting a less invasive alternative for select T1-2 foraminal cases.

- Bone healing achieved in a median of 8 weeks (range: 4–14 weeks).
- No major complications; minor issues included 1 screw loosening and 1 superficial infection.
- Subjective function was graded full in 4 dogs, acceptable in 7.
- Arthroscopy enabled accurate dynamic joint assessment, preferred over static radiographs.
- Use of both orthopedic wire and plating provided secure fixation and improved outcomes.

In Dickson 2024 et al., on VATS for feline chylothorax, which agents were used to visualize the thoracic duct?
🔍 Key Findings
- Objective: To evaluate outcomes and complications of video-assisted thoracoscopic surgery (VATS) for idiopathic chylothorax in 15 cats.
- All 15 cats underwent thoracoscopic thoracic duct ligation (TDL); 13 also had simultaneous pericardectomy, 2 had VATS TDL + laparoscopic cisterna chyli ablation (CCA), and 1 cat had an open CCA.
- Median surgical time was 152.5 minutes (range 60–255).
- Contrast was used intraoperatively in 13 cats; 11 received methylene blue, and 2 received indocyanine green (ICG).
- One intraoperative complication (6%) occurred — a minor intercostal artery laceration. Conversion to open surgery occurred in 3 cases (20%) due to visualization issues or bleeding.
- Postoperative complications occurred in 8 cats (53%), with persistent pleural effusion in 5 cats (33%) being the most common.
- Mortality was high: 4 cats (27%) died or were euthanized before discharge. Only 7 of 11 cats discharged had resolution of effusion, and recurrence occurred in 1.
- Authors concluded that while VATS is technically feasible in cats, it did not improve clinical outcomes compared to open surgery, and feline idiopathic chylothorax continues to have a high mortality rate.

In Rocheleau 2023 et al., on shoulder stabilization, why were anchor insertion angles considered suboptimal in the study?
🔍 Key Findings
- Arthroscopically assisted stabilization with an IAD was feasible in cadaveric canine shoulders using both bone anchor and suture-toggle techniques.
- Suture-toggle repair was successfully performed in all specimens, while bone anchors could not be deployed in 3/10 shoulders, indicating lower feasibility.
- Median surgical time was shorter for the suture-toggle group (25.5 min) compared to the anchor group (37.3 min).
- Postoperative abduction angles returned to baseline in the anchor group, while the suture-toggle group had slightly reduced angles, suggesting possible overtightening.
- Violation of the articular surface occurred in 2 anchor specimens and 1 suture-toggle specimen, but none were considered likely to be clinically significant.
- Overall targeting accuracy using the IAD was 88%, supporting its utility in guiding tunnel/anchor placement.
- CT measurements showed acceptable bone stock and insertion angles, but anchor insertion angles were lower than optimal for mechanical pullout strength.
- Suture-toggle technique was considered simpler and more consistent, with fewer complications and faster execution than anchor placement.
