In Buote 2023 et al., on 3D-printed cannulas in feline laparoscopy, what was the effect on mean surgical time?
🔍 Key Findings
- 3D-printed cannulas (3DPCs) reduced mean surgical time significantly in cadaveric procedures (125.6 vs 95.2 min, p = 0.03).
- Cannula pullout events decreased from a mean of 10 to 2.2 per procedure when using only 3DPCs (p = 0.03).
- Instrument collisions were significantly fewer with 3DPCs (6.8 vs 2.6 collisions, p = 0.03).
- Live patients experienced no postoperative complications, including no incision site infections or discomfort.
- Initial versions of 3DPCs had minor issues, including valve leakage and looser trocar fit, requiring surgical workarounds.
- Customization of cannula shaft length (3 cm vs standard 5–8.3 cm) improved working space and reduced instrument interference.
- Production cost was under $5 per cannula, suggesting 3DPCs may be a cost-effective and reusable alternative for small patients.
- Study supports broader use of 3DPCs in laparoscopic procedures requiring long-jawed instruments or intricate tissue handling.

In Jeon 2025 et al., on distal femoral shortening, which **complication was observed intraoperatively** during the THR procedure?
🔍 Key Findings
- Distal femoral shortening osteotomy (DFSO) enabled prosthesis reduction in all 4 dogs with irreducible luxoid hips undergoing total hip replacement.
- Median femoral shortening ratio was 13.8% (range: 10.7–15.3%) based on intraoperative tension needed for prosthesis reduction.
- Bone union was achieved in all cases post-DFSO, indicating good healing potential.
- Two major complications occurred: one prosthetic luxation and one aseptic stem loosening requiring explantation.
- One intraoperative fracture of the greater trochanter occurred during trial reduction before DFSO.
- DFSO did not result in neurovascular injury, even in cases with significant femoral head displacement (>4 cm).
- Radiographic planning with FHD index and intraoperative assessment were crucial for determining DFSO necessity.
- DFSO avoids complications linked to subtrochanteric osteotomy by preserving proximal femoral anatomy and allowing secure distal fixation.

In Johnson 2022 et al., on PET implant outcomes, what percentage of implants remained fully intact and functional at 6 months postoperatively?
🔍 Key Findings
- Only 2 of 10 PET implants were fully intact and functional at 6 months post-op.
- Owner-reported function (LOAD scores) improved by 51.7% (p = .008) over 6 months.
- Gait asymmetry improved by 86% (p = .002) postoperatively.
- Implant failure occurred in the midbody of the PET device, suggesting fatigue as a failure mechanism.
- One dog (10%) developed implant infection, necessitating implant removal.
- Implant fixation method (screws + washers + interference screw) was mechanically adequate and technically simple.
- Partially intact implants (4/10) still showed improved clinical outcomes, despite structural compromise.
- Midbody tearing and lack of long-term integrity prohibit continued use of this PET implant in CCL repair.

In Latifi 2024 et al., on fascial mapping in the canine hindlimb, which fascial type is associated with periosteum and may require ostectomy for inclusion in surgical margins?
🔍 Key Findings
- This anatomical study mapped fascial planes of the canine hindlimb and pelvis to aid superficial tumor resection.
- Type I fascia (discrete sheets) was suitable for deep margins in fascia lata, lateral crus, and gluteal regions.
- Areas with poor or absent fascia included the ischiorectal fossa, femoral triangle, stifle extensor mechanism, and pes.
- Type IV fascia associated with periosteum (e.g., patella, tibial tuberosity) required partial ostectomy for inclusion in surgical margins.
- Nerves at risk during deep dissection included obturator, superficial peroneal, and tibial nerves, particularly in regions with weak fascia.
- In males, bulbospongiosus muscle could act as a fascial plane but dissection was challenging and potentially hemorrhagic.
- In females, constrictor vulvae/vestibulae muscles were tightly associated with mucosa, limiting clean resection options.
- Distal hindlimb resections often lacked a usable fascial plane, suggesting that amputation or adjuvant therapy may be more appropriate.

In Espinel Rupérez 2023 et al., on feline hip stabilization, which of the following structures was most at risk of impingement due to excessively ventral toggle placement?
🔍 Key Findings
- Arthroscopic-assisted hip toggle stabilization (AA-HTS) was successfully completed in all 14 feline cadaver joints.
- Femoral and acetabular tunnel creation was feasible in all cases, though femoral tunnel placement had a higher rate of deviations.
- Intraoperative complications occurred in 5/14 joints, mostly related to femoral tunnel creation and toggle lodging.
- Minor articular cartilage injury (<10% total cartilage area) occurred in 10/14 joints, but no injury to neurovascular or intrapelvic structures.
- Thirteen surgical technique deviations (8 major, 5 minor) were identified in 7 joints, all involving the femoral tunnel.
- Toggle passage through the femoral tunnel was the most challenging step, being mildly difficult in 6 joints.
- Postoperative CT and gross dissection confirmed all toggles and buttons were in correct position, without damage to major surrounding structures.
- No deviations, complications, or cartilage injuries occurred in the last 4 joints, suggesting a learning curve effect.

In Trefny 2025 et al., on locking plate biomechanics, which configuration showed higher construct stiffness in compression bending?
🔍 Key Findings
- Short working length constructs had significantly higher stiffness and lower strain than long constructs in compression bending (p = 0.0172).
- In tension bending, short constructs also had higher precontact stiffness and lower strain, but this reversed after transcortical contact (~150 N).
- Transcortical contact increased stiffness only in long constructs, producing a bilinear load-displacement curve.
- Postcontact stiffness was higher in long constructs, but this may not reflect clinical benefit due to risks of high interfragmentary strain.
- Short working length reduced strain at multiple ROIs under both loading conditions, including over fracture gap (Tables 1–3).
- Increased working length promoted stress concentration and deformation, especially in compression bending.
- In vitro benefits of long constructs (via contact stability) may not translate to healing, as repetitive loading could increase plate strain and bone resorption.
- Plate strain was effectively mapped using 3D digital image correlation, confirming regional strain differences between configurations.

In Buote 2023 et al., on laparoscopic vertical sleeve gastrectomy (LVSG), on LVSG, what was the primary method used for leak testing after stapling?
🔍 Key Findings
- LVSG was successfully performed in 9/10 cadavers and both live cats, demonstrating procedural feasibility.
- Mean stomach resected was 27.6% of total weight in cadavers, with no leaks in 8/8 tested or either live patient.
- Mean surgical time: 110.4 min (cadavers) and 115 min (live cats); no intra- or postoperative complications observed.
- Stenosis near the incisura occurred in 2 cadavers; attributed to staple placement too close to the lesser curvature.
- 3D printed cannulas (3DPCs) improved ergonomics and were used in 6/10 cadavers and both live procedures.
- Live cats lost 21–24% body weight over 3 months, with full return to pre-surgical BCS and no GI complications.
- Orogastric tube and proper tensioning were critical in preventing gastric stenosis during staple placement.
- No reinforcement or oversew was used on the staple line; TriStaple cartridges provided reliable closure.

In Duvieusart 2025 et al., on lung lobectomy approaches, what was a key advantage of the TDCM technique?
🔍 Key Findings
- Study Design: Canine cadaveric study comparing intercostal thoracotomy (ICT), median sternotomy (MS), and transdiaphragmatic with caudal median sternotomy (TDCM) for accessory lung lobectomy (ALL).
- Main Outcomes:
- Exposure Area: TDCM (193.5 cm²) > MS (106.5 cm²) > ICT (73.5 cm²) (p = .01).
- TDCM provided significantly greater exposure than MS (p = .02) and ICT (p = .02); MS > ICT (p = .04).
- Surgical Time: No significant difference (p = .06).
- Lobe Excision (% by weight/surface area): No significant difference between groups (p = .4).
- Staple Line Leak: Leak at ≤40 cmH₂O in 2/4 ICT, 0/4 MS, 0/4 TDCM (p = .09).
- Complications:
- 1/4 MS cases had iatrogenic damage to an adjacent lobe.
- Technical Insights:
- TDCM approach allowed immediate visualization of all three parts of the right pulmonary ligament.
- The TDCM approach offers improved access without requiring en bloc removal with the right caudal lobe.
- Conclusion: The TDCM approach provides improved exposure for ALL lobectomy with no increase in surgical time or complications relative to other approaches.
