In Ferreira 2025 et al., on tibial torsion measurement, which method had the highest interobserver reproducibility?
🔍 Key Findings
Objective: Validate a new 3D CT-based method for measuring tibial torsion in dogs with MPL, comparing it to a traditional method.
Sample: 40 tibiae from client-owned dogs with MPL (primarily small-breed).
Repeatability (intraobserver):
- New method: ICC = 0.99 → excellent agreement
Reproducibility (interobserver):
- New method: ICC = 0.83 → high agreement
- Traditional method: ICC = 0.52 → moderate agreement
Torsion angle measurements:
- New method avg: 16.00° ± 8.77
- Traditional method avg: 8.76° ± 4.92
Conclusion: The new method is more repeatable, reproducible, and provides higher torsion values than the traditional Aper method, especially reliable for small-breed dogs.

In McLean 2024 et al., why might ECA not have correlated with rock-back in this study?
🔍 Key Findings Summary
- 95 TPLO procedures reviewed retrospectively with follow-up radiographs
- Rock-back defined as increase in tibial plateau angle (TPA) ≥2° from immediate post-op to recheck
- 21% of stifles (20/95) experienced rock-back
- Mean ΔTPA among rock-back cases = 3.2° ± 2.6°
- No implant failures or tibial tuberosity fractures were reported in these cases
- Plate inclination and exit cut angle (ECA) were not associated with increased risk of rock-back (p = 0.4 and 0.2)
- Authors hypothesize that compression across osteotomy in vivo may mitigate torsional effects from ECA, unlike in gap-model studies
- Emphasizes that rock-back is relatively common, even with well-placed implants

In Williams 2024 et al., on adrenaline use in maxillary nerve blocks, what adverse cardiovascular effects were observed due to adrenaline?
🔍 Key Findings
- The addition of adrenaline (0.00198%) to bilateral maxillary nerve blocks significantly reduced intraoperative hemorrhage in dogs undergoing sharp staphylectomy (median reduction: 77.1%).
- Normalized hemorrhage (g/kg) and total hemorrhage (g) were significantly lower in the adrenaline group (p = .021 and p = .013, respectively).
- Surgeon-assessed hemorrhage scores were also significantly lower in the adrenaline group (median 2 vs. 3; p = .029), indicating improved surgical visibility.
- No adverse effects (e.g. tachycardia, arrhythmia, or hypertension) were observed with adrenaline administration.
- A standardized intraoral approach to the maxillary nerve block was used with 0.5 mL per side regardless of dog size.
- Breed effect observed: English Bulldogs had higher normalized hemorrhage, possibly due to anatomical variation or underdosing relative to size.
- Adrenaline may also prolong local anesthetic action and reduce blood aspiration risks, though this was not directly measured.
- The study supports the routine inclusion of adrenaline in maxillary nerve blocks for staphylectomy in BOAS patients to improve surgical field and reduce bleeding.

In Bounds 2023 et al., on feline hip arthroscopy, what tool improved visualization of the dorsal acetabular rim during hip arthroscopy?
🔍 Key Findings
- Feline hip arthroscopy using a supratrochanteric lateral portal was feasible in all cadaveric hips studied.
- All relevant intra-articular structures (femoral head, acetabulum, round ligament, joint capsule, transverse acetabular ligament, dorsal acetabular rim) were consistently visualized.
- Optimal limb positioning (neutral abduction, 90° extension) significantly aided joint distraction and visualization.
- Minor iatrogenic cartilage injury (ICI) occurred in all hips, typically partial-thickness abrasions; one hip had a full-thickness lesion.
- Portal placement did not damage the sciatic nerve or caudal gluteal artery, with a mean distance of 4.3 ± 2 mm between the cannula and nerve.
- Probe use improved visualization of the dorsal joint capsule and dorsal acetabular rim, though not essential.
- Joint evaluation was also successful in hips with DJD, suggesting technique feasibility even in diseased joints.
- Muscle trauma was minimal, with only mild impingement in a few specimens and no gross nerve or vessel injury.

In You 2025 et al., on barbed sutures for lung lobectomy, what was the main advantage of barbed sutures compared to traditional sutures?
🔍 Key Findings
- Barbed sutures showed comparable leakage pressure to traditional sutures and stapling devices (p = .36).
- No bronchial leaks occurred at physiological pressure (<20 cmH₂O) in any group.
- Leakage at supraphysiologic pressure (20–80 cmH₂O) occurred in 90% of stapler, 80% of traditional, and 60% of barbed suture closures.
- Barbed sutures reduced ligation time significantly compared to traditional sutures (10.7 vs. 14.1 minutes, p < .01).
- Staplers remained fastest, with mean ligation time of 2.4 minutes.
- No knot failure or suture breakage was observed in barbed or traditional suture groups.
- Leakage in barbed sutures occurred mostly at the loop effector zone, but remained within acceptable limits.
- Barbed sutures may offer an effective alternative when staplers are unavailable, impractical, or cost-prohibitive.

In Cheon 2025 et al., on guide accuracy in DFO, what was the overall mean angular correction error found using both patient-specific and universal guides?
🔍 Key Findings
- Both patient-specific and universal guides yielded correction errors <2°, with no statistically significant difference in accuracy.
- Universal guide corrected aLDFA up to 24° and AA up to 20°, addressing multiplanar deformities effectively.
- Patient-specific guides allowed for preoperative simulation, providing more stable pin placement and potentially aiding less-experienced surgeons.
- Universal guide eliminated the need for CT-based customization, reducing time and cost.
- Cadaver and bone model trials showed consistent accuracy, validating both methods in vitro and ex vivo.
- No significant differences in outcome when correcting uniplanar (aLDFA) vs biplanar (aLDFA + AA) deformities.
- Universal guide's fixed size presented limitations in small dogs, potentially requiring multiple size options.
- Universal guide showed potential for standard use, offering repeatable outcomes with minimal prep despite needing precise intraoperative placement.

- No significant improvement in VFSS measures of SHH or GER postoperatively (P > .05 for all comparisons)
- Laryngeal ventriculectomy and soft palate resection were performed in all dogs, alaplasty in 14/16
- Aspiration pneumonia occurred in 1 dog immediately post-op and resolved with treatment
- Post-op esophagoscopy results varied, with persistent esophagitis in some cases
- Clinical response was variable, with ~25–30% of dogs being “non-responders” based on owner scoring
- 13/16 dogs showed partial or full clinical improvement, despite no change in objective SHH/GER indicators
- Final follow-up at median 36.5 months showed some dogs still on medical therapy; one underwent further surgery

In Monnet 2023 et al., on barbed vs conventional suture in vesicourethral anastomosis (VUA), how did the number of suture bites compare between the UBS and conventional groups?
🔍 Key Findings
- Leakage pressure was not significantly different between unidirectional barbed suture (UBS) and conventional (C) suture groups (p = .236).
- UBS group had a 28% lower median leakage pressure than the C group (8.6 mmHg vs. 11.7 mmHg), suggesting higher biological risk of leakage.
- UBS significantly reduced suturing time (median 12.7 vs. 17.3 minutes; p < .0002).
- Fewer suture bites were needed in the UBS group (median 14 vs. 19; p = .012).
- No suture breakage or urethral narrowing occurred in either group.
- Leakage site distribution (ventral vs lateral) was similar between groups; no dorsal leaks noted.
- Leakage occurred as low as 5 mmHg in UBS group, indicating potential for postoperative extravasation.
- UBS may aid intracorporeal suturing in minimally invasive prostatectomy, but catheterization remains necessary postoperatively.

In David 2024 et al., on single-port cryptorchidectomy, which location was chosen for laparoscopic port placement?
🔍 Key Findings
- Single-port laparoscopic-assisted cryptorchidectomy (SP-LAC) was feasible in 13/14 dogs with abdominal cryptorchidism.
- Median surgical time was 17 min for unilateral and 27 min for bilateral cryptorchidectomy.
- All testes were successfully exteriorized through a 15-mm mini-celiotomy in most dogs; only 2 needed slight enlargement.
- One major complication occurred (testicular artery hemorrhage, requiring conversion to open surgery).
- Two minor complications involved trocar-related issues (splenic capsule laceration, capnoretroperitoneum).
- No incisional complications were reported postoperatively; some dogs had mild dermatitis at the clipped site.
- The technique requires only one surgeon and no advanced tools beyond a single-port endoscope.
- Low-pressure capnoperitoneum (6 mmHg) was adequate for visualization in most cases.
