In Scott 2023 et al., on thoracoscopic-assisted lung lobectomy, what proportion of dogs **required conversion to open thoracotomy** during surgery?
🔍 Key Findings
- TA lung lobectomy was feasible in dogs ≥3 kg, including those with lesions up to 10 cm.
- 12 intraoperative complications (40%) occurred, with 6 dogs (20%) converted to open thoracotomy, mainly due to adhesions or inability to isolate lobes.
- Postoperative complications occurred in 8 dogs (27%), most were mild (63%), and only 1 death (3%) was reported.
- Median hospitalization was 47 hours; 29/30 dogs were discharged successfully.
- One-lung ventilation (OLV) was attempted in 7 dogs but successfully maintained in only 4.
- Linear staplers had shorter surgery times (median 57.5 min) than endoscopic staplers (80 min).
- Histopathology confirmed neoplasia in 77% of cases, most commonly papillary and bronchioalveolar carcinoma.
- TA lobectomy allows MIS in smaller dogs or with large lesions, avoiding need for full thoracotomy or complex anesthesia/stapling.

In Scortea 2025 et al., on sacroiliac fixation accuracy, which statement regarding sacral bone purchase is correct?
🔍 Key Findings
- 3D-printed drill guide technique (3D-DGT) resulted in fewer suboptimal screw placements than minimally invasive osteosynthesis (MIO) (7.14% vs 42.85%), though not statistically significant.
- Entry point translation (EPT) in the dorsoventral direction was significantly lower with 3D-DGT compared with MIO (p = .009).
- Maximum angular screw deviation (MASD) did not differ significantly between 3D-DGT and MIO in dorsal or transverse planes.
- Ventral cortical breach was the most common error with both techniques, more frequent with MIO.
- Achievement of >60% sacral bone purchase was more consistent with 3D-DGT (92.9%) than with MIO (64.3%).
- Modified Gras grade distribution was similar between techniques, with most screws graded as secure (“a” or “b”).
- 3D-DGT required substantially longer preoperative planning time than MIO (median 34 vs 8.5 minutes).
- Both techniques demonstrated overall acceptable accuracy, emphasizing the importance of CT-based planning and assessment.

In Payne 2024 et al., on HIF propagation pattern, what was the approximate rate of isthmus diameter increase per kilogram of body weight?
🔍 Key Findings Summary
- HIF typically originates 57° caudal to the supratrochlear foramen and propagates cranially in a segmental pattern.
- %HIF correlated significantly with both fissure depth and length:
- %DHIF increased linearly (r = 0.989, p < 0.001)
- %LHIF followed a sigmoidal relationship with %HIF (p < 0.001)
- Higher %HIF was significantly associated with:
- Clinical lameness (p = 0.004)
- Distal shift in the fissure center (CHIF)
- Implant complications in 5/17 elbows treated with transcondylar screws
- Isthmus diameter increased with weight (p = 0.002), relevant for screw sizing

In Farrugia 2025 et al., on BODPUO location effects, which variable most significantly predicted the postoperative change in proximal ulna angle?
🔍 Key Findings
- Proximal BODPUOs (closer to 26–28% of ulna length) resulted in greater increases in proximal ulna tilt postoperatively (up to 18°).
- Distal osteotomies (closer to 48–49%) yielded minimal change in ulna angle.
- Strong linear relationship between osteotomy location and change in angle; correlation coefficient = 0.73.
- Initial proximal ulna angle (IPUA) influences results—angles closer to 90° yielded greater changes.
- Craniocaudal osteotomy angle had minimal impact on tilt change after adjusting for location.
- Osteotomy length had no significant effect on change in angle.
- Prediction intervals showed wide individual variation in outcomes, especially with more proximal osteotomies.
- No increase in complications was associated with more proximal osteotomies, contrary to past assumptions.

In Radke 2022 et al., on outcome measure validation, which of the following OROMs demonstrated the **most rigorous development process** according to COSMIN criteria?
🔍 Key Findings
- CBPI, COI, and LOAD are recommended for assessing canine osteoarthritis based on COSMIN criteria.
- COI scored highest in development rigor and evidence quality among evaluated OROMs.
- Internal consistency, reliability, and responsiveness were commonly validated, though no OROMs reported measurement error.
- LOAD was considered formative, and internal consistency assessment was deemed unnecessary.
- CBPI and COI showed sufficient internal consistency, but CBPI’s factor structure was inconsistent across studies.
- All 6 evaluated OROMs (CBPI, COI, LOAD, BHSII, HCPI, HVAS) were quick to complete (under 5 min).
- Three tools—BHSII, HCPI, HVAS—need more evidence before recommendation; only CBPI, COI, and LOAD are Category A (recommended).
- Future studies should assess interpretability, including measurement error and clinically meaningful change scores (MIC, SDC).

In Miller 2024 et al., on intestinal obstruction and catheter technique in cats, which intraoperative factor did NOT differ significantly between LFBO and DFBO groups?
🔍 Key Findings
- Cats with linear (LFBO) and discrete (DFBO) small intestinal obstructions had similar survival (98.2% vs. 97%, p = 1.0).
- Postoperative complications were not significantly different between LFBO and DFBO cases (p = .1386).
- Intestinal dehiscence was rare (only 2 cats), both in DFBOs, with no statistical difference between groups.
- Red rubber catheter technique (RRCT) successfully removed LFBOs in 83% (20/24) of attempts.
- All failed RRCTs occurred in cats with perforations or tissue nonviability.
- Cats with failed RRCTs had longer clinical signs pre-surgery (median 6.5 vs. 2.0 days).
- Surgical time was longer in LFBO cats (median 77 min vs. 58 min, p = .0018).
- Preoperative septic peritonitis was rare (4/169 cats), but occurred only in linear or mixed FBO cases.

In Saitoh 2025 et al., on CTS stabilization, which group of dogs all returned to work after CTS stabilization?
🔍 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 Lee 2022 et al., on TPLO accuracy, what feature of the 3D-printed guide directly aided in more accurate jig pin placement?
🔍 Key Findings
- 3D-printed TPLO guides significantly reduced osteotomy inclination angle in both bone models and cadaver limbs compared to jig alone (P < .001).
- Torsional deformities were lower when the 3D-printed guide was used in bone models (P < .001), but not significantly different in cadavers.
- Angular deformities were significantly reduced in cadavers using 3D-printed guides (P < .001).
- Proximal jig pin angulation was more accurate with the guide in cadavers (P < .001); not significant in bone models.
- Medial cortex damage was substantially reduced in bone models when the 3D-printed guide was used (P < .001).
- Postoperative tibial plateau angle (TPA) did not differ significantly between groups, suggesting that clinical alignment can still be achieved without the guide.
- Clinical significance of improved metrics is uncertain, but improved precision may reduce surgical complications.
- 3D guide design allowed direct placement of jig and bone plate, potentially improving workflow and safety.

In Burkhardt 2024 et al., on coagulation testing in liver lobectomy, what percentage of dogs had both PT and aPTT prolonged preoperatively?
🔍 Key Findings
- 20.6% of dogs had a preoperative prolongation in PT or aPTT, but only 5.6% had both prolonged.
- Hemangiosarcoma was the only tumor type significantly associated with both PT and aPTT prolongation (37.5% of hemangiosarcoma cases, p < .001).
- Dogs with both PT and aPTT prolongations were 6.5× more likely to have emergency surgery (p < .001) and 2.5× more likely to have hemoabdomen (p = .0022).
- 60% of dogs with both PT and aPTT prolongation required blood transfusion (p < .001).
- Only 1.9% of all dogs had both PT and aPTT prolonged by >25%, suggesting limited clinical utility of routine PT/aPTT testing.
- Platelet count <50,000/μL was rare (1.5%) and not associated with PT/aPTT changes or transfusions.
- Routine PT/aPTT testing offers low diagnostic yield in elective liver lobectomy cases.
- Authors recommend case-by-case PT/aPTT screening, especially when hemangiosarcoma or bleeding tendencies are suspected.

In Trefny 2025 et al., on plate length and stiffness, what was the measured effect of plate length on plate strain?
🔍 Key Findings
- 12-hole LCPs (80% plate–bone ratio) showed significantly higher construct stiffness than 6-, 8-, or 10-hole plates in both compression and tension bending.
- Strain on the plate was significantly lower in 12-hole vs 6-hole plates at all regions of interest (ROIs), especially around the fracture gap.
- No incremental increases in stiffness or decreases in strain were observed between 6-, 8-, and 10-hole plates—only when comparing to 12-hole plates.
- Bone model strain adjacent to the plate end was significantly lower for 10- and 12-hole plates vs 6-hole plates under both loading conditions.
- The threshold effect suggests biomechanical benefits only emerge beyond a plate–bone ratio of ~80%.
- Working length increased from 9.4 mm (6-hole) to 13 mm (others), potentially influencing strain/stiffness differences.
- Four-point bending was used, as it replicates the most biomechanically relevant force on plated long bones.
- Clinical implication: Longer plates may reduce plate strain and peri-implant bone strain, potentially lowering risk of fatigue failure or stress risers.
