In Downey 2023 et al., on lung lobectomy for pulmonary consolidation, what was the most common perioperative complication in dogs undergoing lung lobectomy?
🔍 Key Findings
- Thoracoscopic (TL) and thoracoscopic-assisted (TAL) lobectomy were performed in 12 dogs with non-neoplastic pulmonary consolidation.
- 44% (4/9) of TL cases required conversion, most often due to pleural adhesions or poor visualization — a higher rate than for neoplastic lobectomies.
- Surgical mortality was 8.3% (1/12 dogs), with death attributed to unaddressed BOAS, not surgical complications.
- All 11 surviving dogs had no recurrence of clinical signs at a median 24-month follow-up.
- Perioperative complications occurred in 58% (7/12): pneumothorax (2), hemorrhage (3), wound dehiscence (1), progressive pneumonia (1).
- One-lung ventilation (OLV) was successful in 78% of TL dogs but may be harder to achieve in brachycephalic breeds.
- Most dogs had infectious pneumonia (10/12), with bacterial causes identified in 8; fungal and viral etiologies were less common.
- Hospitalization was short, with median stays of 3–4 days depending on approach and conversion status.

In Johnson 2022 et al., on PET implant outcomes, what was the most common site of failure identified in torn implants?
🔍 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 Jenkins 2022 et al., on medial epicondylar fissure fracture, what was the general clinical outcome for cases with MEFF during the perioperative period?
🔍 Key Findings
- MEFF occurred in 11.4% (10/88 elbows) following medial-to-lateral transcondylar screw placement in dogs with HIF.
- Screw size to condylar height ratio >41% significantly increased MEFF risk (P = .004, OR 1.52).
- MEFF was not recognized intraoperatively in 60% of cases and was only seen on follow-up or retrospective imaging review.
- Screw loosening was the most common complication (11.2%), observed both with and without MEFF.
- MEFF tended to increase the risk of screw loosening (P = .06), but was not statistically significant.
- Most MEFFs did not require treatment and healed radiographically by 14–17 weeks in monitored cases.
- Shaft screws were used in all MEFF cases, but shaft vs cortical design was not significantly associated with MEFF.
- The clinical impact of MEFF was minor in most cases, although long-term significance is unknown.

In Miller 2025 et al., on spinal drill guide accuracy, how long did it take to apply each drilling guide during surgery?
🔍 Key Findings
- 3D-printed, SOP plate-specific guides enabled safe screw placement from T12–L5 in canine cadavers and models.
- All 140 screw trajectories were classified as Zdichavski Grade 1, indicating optimal placement without vertebral canal breach.
- Screw angles (cranial-caudal and transverse) matched preoperative planning, with no significant deviation.
- Entry/exit point deviations were <1 mm on average, deemed clinically negligible.
- Drill guides were quick to place (<30 sec per vertebra) and improved ease of surgery.
- Plates acted as effective reduction tools, guiding alignment during screw placement in mobile spines.
- Minor technical challenges arose from cadaveric spine mobility, mitigated by sequential screw insertion.
- Technique may enable future use in fracture/luxation reduction, pending further cadaveric and clinical trials.

In González Montaño 2023 et al., on traumatic pulmonary pseudocysts (TPP), what was the most common concurrent thoracic injury in patients with traumatic pulmonary pseudocysts?
🔍 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 Peng 2025 et al., on topical amikacin gel, what was the highest observed serum amikacin concentration?
🔍 Key Findings
Objective: Determine if topical 45 mg/mL amikacin in CMC gel leads to systemic absorption in dogs with wounds.
Dogs enrolled: 11 client-owned dogs, with 31 applications of the gel.
Serum findings:
- Only 5 of 153 samples were above the 2.5 µg/mL quantification limit
- All values remained <5 µg/mL, the presumed toxicity threshold
- No correlation was found between dose-related parameters (mg, mg/kg, mg/cm²) and serum amikacin levels
Peak concentrations were observed at ~2 hours post-application, declining rapidly thereafter
No nephrotoxicity observed, and most values were below detection
Conclusion: Topical amikacin gel appears safe at doses up to 24.9 mg/kg, with minimal systemic absorption

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.

In Buote 2023 et al., on laparoscopic gastrectomy in cats, what was the primary purpose of the cadaveric phase of the study?
🔍 Key Findings
- LVSG was feasible in 9/10 feline cadavers with successful stapled gastrectomy and minimal technical complications.
- Stenosis at the incisura angularis occurred in 2/10 cadavers, associated with staple placement too close to the lesser curvature.
- Leak testing was negative in 8 cadavers and both live cats, indicating effective staple sealing.
- Mean stomach resection was ~28%, though less than human standards (~75–80%) for metabolic effects.
- Surgery was performed safely in two live feline subjects, with no intraoperative or postoperative complications over a 6-month follow-up.
- Technique refinements included orogastric tube placement and custom 3D-printed cannulas to improve staple line accuracy and avoid stenosis.
- Tri-Staple purple cartridges provided graduated compression suited for feline gastric tissue thickness (~2.5 mm).
- No need for staple line oversew in live cats; staple-only closure proved safe in this short-term study.

In Lomas 2025 et al., on hybrid THR in cats, what was the reported mean sf-FMPI (feline musculoskeletal pain index) score at medium-term follow-up?
🔍 Key Findings
- Hybrid THR in cats showed no major complications across 17 hips in 15 cats, including 2 bilateral cases.
- Postoperative radiographs confirmed stable implant positioning with no loosening, migration, or dislocation in follow-up imaging.
- Mean owner satisfaction was high, with a mean short-form feline musculoskeletal pain index (sf-FMPI) score of 2/36 at a mean follow-up of 438 days.
- SCFE (slipped capital femoral epiphysis) was the most common indication, seen in 13/17 hips.
- Partial tenotomy of rectus femoris origin resolved intraoperative medial patella luxation in 3 cases—no cats required surgical correction later.
- A micro BFX cup allowed for increased acetabular offset, possibly reducing luxation risk even when using a +0 femoral head offset.
- Hybrid THR was successfully used as a revision for failed CFX THR due to recurrent luxation—implants remained stable post-revision.
- Use of oversized cups (12 mm) with shallow seating or medial breach still resulted in stable outcomes, suggesting good implant fixation even with reduced bone stock.
