In Buote 2023 et al., on 3D-printed cannulas in feline laparoscopy, what technical issue occurred with the 3DPC during live surgery case 1?
🔍 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 Bayrakdarian 2026 et al., on feline skin perfusion, which study design element helped minimize inter-individual variation when comparing closure techniques?
🔍 Key Findings
- A within-animal randomized controlled trial was performed in 32 adult cats undergoing ovariohysterectomy, allowing direct comparison of two intradermal skin-closure patterns in the same incision.
- Each 4-cm ventral midline incision was divided into cranial and caudal halves, randomly assigned to either a modified Allgower-Donati (mAD) intradermal pattern or a standard intradermal horizontal mattress pattern (SP).
- The modified Allgower-Donati pattern significantly increased wound-edge perfusion, whereas the standard intradermal horizontal mattress pattern decreased perfusion.
- Mean perfusion change was +59.7 ± 124.1 BPU with mAD versus −20.2 ± 119.9 BPU with SP (p < .01), demonstrating improved acute microcirculation with the mAD technique.
- Relative perfusion increased by 115.3% with mAD but decreased by 24.1% with SP, reinforcing the perfusion advantage of the modified pattern.
- The critical technical difference was suture bite orientation: mAD placed dermal bites perpendicular (90°) to the incision, while the standard pattern placed bites parallel and close to the wound edge.
- Both techniques used buried continuous intradermal closure with 4-0 poliglecaprone, maintaining the cosmetic and patient-comfort advantages of intradermal suturing.
- No incisional complications were reported within 30 days, although follow-up relied on re-presentation rather than scheduled examination, limiting detection of minor complications.

In Duffy 2022 et al., on barbed suture oversew, what was the **most common leakage site** among all FEESA groups regardless of suture type?
🔍 Key Findings
- Oversewing the transverse staple line using barbed suture showed no difference in initial (ILP) or maximum leakage pressure (MLP) compared to monofilament suture (p = .439 and .644).
- Barbed suture repairs were ~18% faster (25 seconds faster; p < .001) than monofilament suture.
- No difference was found between unidirectional and bidirectional barbed sutures in leakage resistance or repair time (p = .697).
- Mean ILP and MLP were significantly higher in control jejunal segments (6.6x and 5.1x greater respectively; p < .001).
- Leakage consistently occurred at the crotch of the FEESA in all oversew groups (>80%), not the staple line.
- All oversewn techniques leaked at supraphysiologic pressures, indicating clinical safety against in vivo leakage.
- No leakage was observed from barbed suture holes, addressing concerns of tissue trauma due to barb design.
- The study supports barbed suture as a viable alternative to conventional monofilament suture for FEESA oversew in dogs.

In Hawker 2025 et al., on locking head inserts, what did the authors conclude regarding high-strain construct scenarios?
🔍 Key Findings
- Adding Locking Head Inserts (LHI) to a 3.5-mm LCP had no effect on plate strain, stiffness, or deformation in an open fracture gap model.
- Peak strain consistently occurred at the Combi-hole over the fracture gap, with values up to ~1837 µε.
- No significant difference in strain was found across configurations with 0, 3, or 9 LHI (p = 0.847).
- Construct stiffness and compressive displacement also remained unchanged regardless of LHI count (p = 0.311 and 0.069 respectively).
- Study contradicted the hypothesis that LHI would reduce strain and increase stiffness under biologic loading.
- Combi-hole design may limit the efficacy of LHI, as LHI only fill the locking portion, not the compression side where strain peaks.
- Implant fatigue risk remains highest over unfilled screw holes, especially over fracture sites—confirming previous failure patterns.
- Surgeons should consider alternative methods to reduce strain when facing high implant load scenarios.

In Weichert 2026 et al., on feline CMF fractures, which fracture type was most commonly responsible for obstruction of the nasal or nasopharyngeal airway?
🔍 Key Findings
- Mandibular fractures were the most common injury, occurring in 40/48 cats, often affecting multiple mandibular regions simultaneously.
- Temporomandibular joint (TMJ) injuries were frequent, present in 27/48 cats, with 23 fractures and 4 luxations, most commonly involving the condylar process.
- Maxillofacial fractures involving nasal and palatal structures occurred in 36/48 cats, frequently producing airway obstruction due to fragment displacement or swelling.
- Orbital fractures occurred in 30/48 cats, predominantly affecting the dorsomedial orbital wall and often associated with nasal airway obstruction.
- Pterygoid bone fractures (25/48) were clinically important, frequently causing medial displacement and obstruction of the nasopharyngeal airway.
- Combined involvement of multiple functional systems was common, with 36/48 cats showing concurrent injuries affecting oral cavity and nasal airway function.
- Neurocranial fractures were uncommon (6/48) but occurred only in cases with severe, multifocal CMF trauma.
- CT imaging was essential for diagnosis, as many orbital and skull fractures were difficult or impossible to detect clinically.

In Burton 2023 et al., on CHAPS plate design, what major benefit does the CHAPS system offer during surgery?
🔍 Key Findings
- The Canine Humeral Anatomic Plating System (CHAPS) was designed using CT-based 3D modeling of 100 canine humeri from 5–50 kg.
- Four plate sizes (TP1–TP4) were developed to accommodate a wide range of canine body sizes.
- Plate contour fit was evaluated across 48 cadaveric limbs and showed a 97.5% median surface match, demonstrating excellent topographic conformity.
- Screw hole placement avoided 95–100% of critical anatomical structures including the supratrochlear foramen and nutrient foramen.
- The plates were designed for use with locking screws, improving biomechanical stability for humeral diaphyseal fractures.
- CHAPS plates showed consistent alignment with humeral curvature in both craniocaudal and mediolateral planes.
- CT data revealed marked breed and size variation, but the multi-size design achieved broad anatomical applicability.
- The system provides an anatomic solution with potentially fewer intraoperative contouring needs and reduced iatrogenic risk.

In Perez Neto 2025 et al., on hip resurfacing arthroplasty, what was the impact of implant positioning (neutral vs valgus) on biomechanical performance?
🔍 Key Findings
- In an ex vivo study of 20 canine femur pairs, implantation of a novel hip resurfacing arthroplasty (HRA) prosthesis reduced maximum load (ML) by 22% and load at collapse (LC) by 27% vs. intact controls (p ≤ 0.05).
- Displacement at maximum load (DML), displacement at collapse (DC), and stiffness (k) were not significantly different between prosthesis and control groups.
- Both groups showed similar failure patterns, with 92% failing at the femoral neck.
- All prosthetic femurs still withstood ~6.2× body weight — exceeding estimated in vivo peak loads (~1.64× BW).
- Prosthesis positioning (neutral vs valgus) had no significant effect on biomechanical outcomes.
- Implant design preserved more metaphyseal bone stock than total hip replacement, possibly explaining the smaller load reduction compared to other short-stem prostheses.
- The press-fit cobalt–chromium design with conical stem allowed full contact and stress distribution over the femoral head/neck.
- Authors conclude the device has adequate immediate biomechanical strength for clinical use, though long-term in vivo studies are needed.

🔍 Key Findings
- 67.9% of respondents reported using SSCs, with most indicating frequent use (64% used in every surgery).
- 78.7% agreed SSCs reduce complications, and 89.6% believed SSCs improve communication.
- Respondents not using SSCs were more likely to view them as a waste of time (p < .001).
- Forgetfulness (39.6%) and time constraints (36.5%) were leading reasons for checklist noncompletion.
- Only 23.3% had SSC training during surgical residency, with newer diplomates more likely to have had exposure (p < .001).
- Key strategies to improve uptake included: staff feedback modifications (67.9%), formal designation of initiator (48.6%), and training (52.2%).
- Surgeons and OR staff were most commonly identified as noncompliant team members.
- SSC use was more frequent in small animal practices, and mandating SSCs by management was favored but not always effective alone.
