In Mullen 2023 et al., on microvascular perfusion, which of the following statements best reflects the accuracy of subjective assessment of intestinal viability?
🔍 Key Findings
- Microvascular density at the site of foreign body obstruction was significantly lower in obstructed dogs compared to healthy controls.
- PBR (perfused boundary region) was paradoxically lower in obstructed dogs, indicating that PBR may not reliably correlate with tissue viability in this context.
- No significant difference in microvascular perfusion between subjectively viable vs nonviable intestines, suggesting subjective assessment is unreliable.
- No difference in perfusion parameters between handsewn and stapled enterectomies, indicating both techniques preserve vascular health equally.
- Stapled enterectomy using green TA staples is safe and did not impair intestinal perfusion at the anastomosis site.
- SDF videomicroscopy is feasible intraoperatively and can differentiate healthy from diseased intestine in dogs.
- Surgeons' subjective evaluations led to potentially unnecessary enterectomies, as microvascular parameters did not differ.
- No cases of dehiscence or mortality, suggesting both surgical approaches are effective when applied properly.

In De Moya 2023 et al., on femoral pinning outcomes, what rationale was given for elective pin removal in young dogs?
🔍 Key Findings
- FGPP (fluoroscopic-guided percutaneous pinning) resulted in successful healing in 10/13 fractures, with good limb function.
- Complications occurred in 5 of 11 cases, including intra-articular implants, malunion, implant failure/nonunion, and implant migration.
- Cases with delayed surgery (>15 days) or radiographic remodeling were more likely to experience major complications.
- Most fractures (10/13) were classified as Salter-Harris type I with mild displacement.
- Median surgical time was 60 minutes, and no conversions to open surgery were needed.
- Postoperative femoral neck resorption was minimal, suggesting possible benefits of the minimally invasive approach for preserving vascular supply.
- One intra-articular pin led to progressive joint disease and required femoral head ostectomy.
- FGPP appears best suited for acute, minimally displaced fractures in young dogs (<8 months) with planned elective explant to avoid growth disturbance.

In Zingel 2026 et al., on canine ankle replacement approach, which biomechanical parameter increased significantly after both medial and lateral cTAR implantation?
🔍 Key Findings
- A lateral surgical approach can successfully implant a canine total ankle replacement (cTAR) prosthesis with accurate implant orientation and stable joint mechanics.
- Post-implantation angular laxity was greater after the lateral approach (15.5°) than the medial approach (9.5°, p = 0.044), though joints remained within acceptable stability limits.
- External rotational laxity increased after implantation with both approaches (lateral +5.4°, medial +6.7°), suggesting mild postoperative rotational laxity likely related to soft-tissue dissection.
- Implant alignment differed minimally between approaches, with most alignment differences <4°, indicating comparable surgical accuracy.
- Bone–implant interface gaps were small and similar between approaches, with ~96% of gaps <1 mm, indicating excellent implant seating.
- Damage to the short lateral collateral ligament occurred in 4/5 lateral-approach limbs, likely due to its insertion near the talar articular surface.
- Technical challenges with the lateral approach included COR post placement and fibular fragment retraction, sometimes leading to slightly proximal implant milling.
- Clinical implication: A lateral approach is a viable alternative when medial exposure is difficult (e.g., medial implants, fibrosis, or abnormal medial malleolus), though ligament injury risk must be considered.

In Scheuermann 2023 et al., on femoral MIPO alignment, which of the following was significantly different in the FRS group compared to the virtual plan?
🔍 Key Findings
- Precontoured plates using 3D-printed femoral models achieved near-anatomic alignment in all cadaver limbs.
- Fracture reduction system (FRS) required significantly fewer fluoroscopy images than intramedullary pin (IMP) methods (7 vs 26, P = .001).
- Despite longer surgical time (43 vs 29 minutes, P = .011), FRS showed equally accurate or better alignment compared to IMP.
- Femoral length, frontal, sagittal, and axial alignment were all within near-anatomic thresholds (<10 mm or <5° deviation) in both groups.
- FRS was associated with more consistent length maintenance, with IMP showing a median shortening of 2.3 mm (P = .03).
- Axial plane deviation was statistically different in the FRS group (P = .04), but still clinically acceptable.
- Study highlights potential for custom 3D-printed guides to reduce radiation exposure and improve precision in MIPO procedures.
- Authors caution that FRS was time-consuming and cumbersome, suggesting design refinements needed for clinical use.

In Forzisi 2026 et al., on stifle locking plate immobilization, what was the typical planned time for implant removal after surgery?
🔍 Key Findings
- Temporary transarticular locking plates successfully immobilized the stifle joint for protection of primary repairs (e.g., ligament reconstruction or articular fracture fixation) in dogs and cats.
- 15 stifle joints in 13 patients met inclusion criteria (9 dogs, 4 cats) treated for injuries such as patellar fracture, patellar ligament rupture, stifle luxation, and femoral condylar fractures.
- The plate was contoured along the medial distal femur and proximal tibia, immobilizing the joint at 135–145° extension with at least three screws in each bone segment.
- Implant removal occurred at a median of 58 days (range 27–96), aligning with the planned ~6-week immobilization period intended to protect repair while limiting cartilage damage.
- No intraoperative complications were reported, and all animals were able to ambulate comfortably postoperatively.
- One major complication (plate breakage at 19 days) required early removal and temporary orthotic support.
- Four minor complications involved plate breakage occurring after the recommended removal time, often related to delayed follow-up appointments.
- Respecting the planned 6-week implant removal is important to prevent implant failure, and dedicated anatomically designed plates may further improve technique reliability.

In Timmermans 2026 et al., on soft palate changes post-BOAS surgery, which of the following statements best describes the postoperative change in middle thickness (MTH) after folded flap palatoplasty (FFP)?
🔍 Key Findings
- Soft palate length, volume, and cross-sectional area decreased significantly after both folded flap palatoplasty (FFP) and standard staphylectomy (STS).
- Middle thickness (MTH) of the soft palate decreased after STS but increased after FFP, indicating FFP may not thin the soft palate long-term.
- Rostral thickness (RTH) increased in both groups, suggesting regional variation in healing or remodeling.
- Clinical improvement (exercise tolerance) occurred in most dogs: 6/8 in FFP and 10/10 in STS group.
- One major complication in FFP group led to death despite revision surgery; another mortality occurred in STS group (likely due to severe laryngeal collapse).
- No difference in minor complication rates between FFP and STS groups.
- Histological remodeling or edema may explain lack of MTH reduction in FFP at 3 months.
- Immediate postoperative imaging may be needed to evaluate initial reduction effects of FFP.

In Ritson 2025 et al., on feline hilar lobectomy sealants, what was the **design benefit** of the double-shank (DS) titanium clip?
🔍 Key Findings
- No leakage occurred using pretied ligature loops (PLL) or double-shank (DS) titanium clips up to 40 cm H₂O airway pressure.
- 1/10 stapled lobes leaked at supraphysiologic pressure (40 cm H₂O), but this was not statistically significant (p = .33).
- All techniques sealed effectively under physiologic and supraphysiologic pressures in cadaveric feline lungs.
- PLL and DS clips required less working space than staplers, making them more practical for small thoracic cavities.
- DS titanium clips offer enhanced security due to dual shanks and tissue-gripping design, reducing clip slippage.
- Leak testing was cyclic and submerged, simulating physiologic ventilation and allowing robust evaluation.
- Stapling failure occurred along the staple line, highlighting risks of air leakage due to staple misalignment or poor hilar access.
- PLL and DS clips may be cost-effective and efficient alternatives for open or minimally invasive feline lung lobectomy.

🔍 Key Findings
- Buccal transposition flap provided successful closure of large maxillary lip defects in all 5 dogs
- All flaps survived, with 3 dogs experiencing minor complications (e.g., fistulas, dehiscence) that resolved
- Flap vascularization originated from the angularis oris and superior labial arteries, as confirmed via CT angiography
- Excellent cosmetic and functional outcomes were achieved in all cases
- Ex vivo cadaver study validated flap perfusion, showing consistent contrast filling of key arteries
- Oronasal fistulas occurred in 2 dogs at the palatal incision site, likely due to contact with the mandibular canine tooth
- Mandibular canine coronectomy was performed in 2/5 dogs to prevent flap trauma
- Flap design and commissure positioning were customizable, aiding tension relief and improving outcomes

In de Moya 2023 et al., on FGPP of femoral capital physeal/neck fractures, what was the overall healing outcome?
🔍 Key Findings
- 11 dogs, 13 fractures (mostly Salter-Harris type I) were repaired with FGPP using Kirschner wires.
- 10/13 fractures achieved satisfactory healing with good limb function at ~43 days median follow-up.
- Major complications occurred in 5 dogs: intra-articular pin placement, implant migration (2), implant failure with nonunion, and malunion.
- 2 dogs presenting >15 days post-injury with radiographic remodeling were poor candidates → higher risk of nonunion/malunion.
- Preoperative displacement was mostly mild (10/13 fractures); these had better outcomes than chronic or severely displaced cases.
- Median surgical time: 60 minutes (range 45–75), all performed percutaneously without conversion to open.
- Elective pin removal was performed in 5 cases; migration occurred with both short and long cut wires.
- Femoral neck resorption (“apple-coring”) was rare (2/10 healed cases) and thought to be less frequent than after ORIF due to reduced vascular disruption.
