In Scheuermann 2023 et al., on canine femoral MIPO, which alignment parameter was statistically different from the preoperative virtual plan in the FRS group but remained within near-anatomic range?
🔍 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 González Montaño 2023 et al., on traumatic pulmonary pseudocysts (TPP), which management strategy was used in the majority of TPP cases?
🔍 Key Findings
- Traumatic pulmonary pseudocysts (TPP) were diagnosed in 11 patients (9 dogs, 2 cats) using CT after blunt trauma.
- TPPs were identified on radiographs in 64% of cases that were CT-confirmed, highlighting the superior sensitivity of CT.
- Most cases (7/10) were managed conservatively, with complete recovery and no TPP-related mortality.
- Thoracic surgery (lung lobectomy) was performed in 3 dogs, due to persistent pneumothorax or large TPP with perceived risk of complications.
- All pneumothorax cases were managed with thoracostomy tubes, and chest drains were used in 73% of cases.
- Pneumothorax was present in 100% of patients, often bilateral, and pulmonary contusions were reported in 73%.
- One cat was euthanized due to unrelated maxillofacial trauma; no deaths were attributed to TPP itself.
- Long-term follow-up (median 768 days) revealed only 1 case with possible TPP-related pneumonia; others had no complications.

In Dalton 2023 et al., on acetabular fracture repair, what was a key advantage of using locking screws in the plate application?
🔍 Key Findings
- Minimally invasive repair of acetabular fractures using precontoured plates on 3D-printed models is feasible and technically reproducible in dogs.
- All cadavers had fracture gaps <2 mm and step defects <1 mm, indicating accurate reduction.
- Sciatic nerve injury was minimal or absent in all cases, supporting potential neuroprotection from indirect approaches.
- Pelvic angulation was maintained <5°, confirming preservation of alignment post-reduction.
- Surgical time averaged ~46 minutes in cadavers for both approaches and repair.
- Clinical case showed good radiographic healing by 8 weeks and full union by 3 months, with early weight-bearing post-op.
- Use of locking screws improved reduction fidelity, particularly across a broad plate span.
- 3D printing accelerated surgical planning, though its necessity remains debated due to the availability and cost concerns.

In Fink 2025 et al., on Roux-en-Y outcomes, which finding was associated with better survival outcomes post-surgery?
🔍 Key Findings
- Roux-en-Y procedures were successfully completed in all 11 cases (6 dogs, 5 cats), despite case complexity and disease severity.
- Median survival post-discharge was longer in cats (365 days) vs. dogs (82 days), with better outcomes in non-neoplastic vs. neoplastic disease (192 vs. 5 days).
- Complication rate was high, with septic peritonitis, dehiscence, and cardiac arrest as leading causes of postoperative death; mortality rate = 36%.
- Dehiscence rate was 8.6% (2 of 23 anastomoses), considered lower than typical rates for GI anastomoses in high-risk patients.
- Feeding tubes (gastrostomy/jejunostomy) were used in all cases, enabling early nutritional support and stomach decompression.
- Postoperative nausea and vomiting were common but mostly self-limiting; managed with metoclopramide, cisapride, and antiemetics.
- Choledochojejunostomy was preferred when common bile duct was dilated, offering a favorable size match and potentially reducing bile leakage.
- Roux-en-Y reduced typical Billroth II complications (e.g., bile reflux, afferent loop syndrome, dumping syndrome), with none observed in discharged patients.

In Anderson 2023 et al., on French Bulldogs with humeral condylar fractures, what percentage of French Bulldogs had a humeral intracondylar fissure (HIF) in the contralateral limb when CT was performed?
🔍 Key Findings
- Lateral humeral condylar fractures (LHCF) were most common, comprising 63.6% of cases.
- Transcondylar screw (TCS) + K-wire(s) fixation had a 7.62x higher risk of major complications compared to other methods (p = .009).
- All cases of TCS migration occurred in the TCS + K-wire group; none occurred with plate fixation.
- Overall complication rate was 40.9%, with 29.5% being major and requiring intervention.
- Contralateral humeral intracondylar fissures (HIF) were found in 58.1% of French Bulldogs with CT data.
- No significant association between age and presence of HIF, but fissure length increased with age (R = 0.47, p = .048).
- Younger, lighter dogs had higher complication and screw migration rates, possibly due to softer bone and smaller condyles.
- TCS + plate fixation had the lowest complication rate, suggesting biomechanical superiority.

In Vandekerckhove 2024 et al., what value did the LImax range across all cadavers?
🔍 Key Findings Summary
- Used VMBDmD to quantify hip laxity under increasing force in cadaveric dogs (n=34).
- 90% of hips reached ≥90% of LImax at 95.32 N, defining this force as sufficient for subluxation.
- LImax was not significantly influenced by osteoarthritis, weight, sex, or limb side.
- Position of device (lever length) influenced rate of laxity acquisition, not final LImax.
- LI curves were repeatable across 5 sessions, indicating elastic—not plastic—deformation.

In Meltzer 2022 et al., on femoral implant selection, which statement best describes the complication rate among dogs undergoing total hip replacement?
🔍 Key Findings
- Hybrid implants were used in older, heavier dogs with lower canal flare index (CFI) compared to cementless types.
- CFI <1.8 was associated with higher risk of femoral fracture or stem subsidence with cementless implants.
- Total complication rate was 14%, with catastrophic complications in only 1.5%—lower than reported in other studies.
- No significant difference in complication rates across implant types (BFX, BFX-C, hybrid).
- Femur fractures were rare (2.9%), lower than in prior studies, and successfully managed with cerclage/plate fixation.
- Coxofemoral luxation was the most common complication (8 cases); all occurred within 62 days post-op, mostly resolved with revision.
- Collared BFX stems did not significantly reduce complications, though they may limit stem subsidence.
- An implant selection algorithm was proposed, using age ≥7 years, weight ≥45 kg, and CFI <1.8 to guide cemented vs. cementless stem use.
