In Tobias 2025 et al., on frontal sinus mucoceles, what was the most common presumed etiology in affected dogs?
🔍 Key Findings
- Frontal sinus mucoceles occurred in young dogs, often linked to prior skull trauma by 10 months of age.
- All dogs presented with expansile, fluid-filled lesions causing facial swelling; CT showed multicentric bone erosion, including the frontal bone and cribriform plate.
- Surgical options included frontal sinusotomy with either sinus lining ablation or re-establishment of nasofrontal drainage, with or without stenting.
- Nasofrontal stenting led to long-term resolution in most dogs, although recurrence occurred in 4/8 dogs, requiring revision surgery in 3.
- Complications were minor and included swelling or nasal discharge; no intraoperative complications were reported.
- Histology confirmed sterile mucoceles with neutrophilic inflammation and mucin, and cultures were negative in all cases.
- Guaifenesin was used postoperatively in several cases to reduce mucus viscosity; its benefit is unproven in dogs but may support drainage.

In Dekerle 2022 et al., on ectopic ureter correction, how did **CLA compare to neoureterostomy** in terms of recurrence of incontinence?
🔍 Key Findings
- Cystoscopic-guided laser ablation (CLA) was associated with significantly fewer minor complications (13%) than neoureterostomy (100%) (P < .01)
- CLA resulted in significantly fewer recurrences of incontinence compared to neoureterostomy (0/7 vs 5/12; P < .05)
- 80% of dogs achieved continence within 1 month postoperatively, with a median continence score of 10
- Long-term continence was achieved in 88% of dogs, with or without adjunctive treatment, over a median of 66 months
- Major complications occurred in only 8% of dogs, and all were successfully managed with surgical revision
- Persistent ureteral remnants were seen only in neoureterostomy dogs, potentially contributing to incontinence recurrence
- All dogs with incontinence recurrence responded to medical treatment, while only 1/5 with persistent incontinence after surgery did
- CLA is recommended over open surgery for iEU correction, due to lower complication and recurrence rates

In Fracka 2023 et al., on patient-specific guides, what did NOT significantly differ between PSG and generic guide groups?
🔍 Key Findings
- 3D-printed patient-specific guides (PSGs) improved tibial cut alignment in the frontal plane compared to generic guides (mean error 1.03° vs 2.41°, p = .036).
- All tibial cuts using PSGs were within 3° of target alignment, while 2/8 of the generic group were outliers.
- PSGs significantly improved sagittal alignment of both distal (p = .018) and cranial (p = .043) femoral cuts.
- No significant difference was found in varus-valgus femoral alignment or closing angle between PSG and generic guide groups.
- Tibial sagittal slope alignment was not significantly different between groups.
- PSGs provided better intraoperative usability, including improved visibility, no loosening, and ease of use.
- Femoral sizing and component fit were equivalent between PSGs and generic guides, ensuring proper prosthesis alignment.
- PSGs may offer training advantages for novice surgeons, especially in anatomically complex or deformed joints.

In Muroi 2025 et al., on refracture risk, what screw-to-bone diameter ratio (SBDR) is suggested as a **threshold** for increased refracture risk in growing dogs?
🔍 Key Findings
- Refracture occurred in 5.5% of limbs, with higher incidence in the plate removal group (12.5%) vs. non-removal (3.5%).
- In the non-plate removal group, refractures occurred at the most distal screw site, linked to greater screw position change during growth (OR 1.79, p=0.04).
- Screw-to-bone diameter ratio (SBDR) >0.4 was a significant risk factor for refracture in the plate retention group.
- In the plate removal group, refractures occurred at the original fracture site, associated with lower pixel value ratio (bone mineral density) and reduced radial thickness.
- Implant-induced osteoporosis (IIO) beneath the plate likely contributed to refracture risk after plate removal.
- Younger age at fracture (<6 months) was associated with higher refracture risk due to ongoing radial growth and shifting screw position.
- No significant association was found between refracture and plate type (locking vs conventional), fixation method, or ulnar union.
- Recommendations include careful SBDR sizing, motion restriction, and cautious plate removal decisions in growing dogs.

In Neal 2023 et al., on transcondylar screw placement, what was the main finding comparing trajectory angle between aiming device and fluoroscopy in right thoracic limbs?
🔍 Key Findings
- Aiming device provided comparable trajectory accuracy to fluoroscopy, especially in right limbs (1.9° vs. 3.4°, p = .0128).
- Eccentricity (deviation from condylar center) was lower with fluoroscopy (3.1 mm vs 4.2 mm, p = .0017), making fluoroscopy more precise.
- Odds of joint infringement were 8× higher with the aiming device, though not statistically significant (p = .0575).
- Residents had greater screw trajectory deviation than diplomates (p = .0366), highlighting impact of experience.
- Aiming device procedures took less time than fluoroscopy in some scenarios, particularly for right limbs with right-handed surgeons.
- Fluoroscopic procedures had more pin/drill attempts, increasing risk of glove puncture and potential aseptic breaks.
- Mean deviation angles in both groups (<3.5°) were within acceptable range to avoid intracondylar fracture gap.
- Cadaver model used large-breed, healthy adult dogs, not small-breed immature dogs, limiting generalizability.

In Schmutterer 2024 et al., on stifle flexion angle effects, how did the center of force shift during increased stifle flexion?
🔍 Key Findings Summary
- Biomechanical study on 14 hindlimbs from Retrievers (cadaveric)
- Three stifle flexion angles tested: 125°, 135°, and 145°
- Contact Force Ratio (CFR) was significantly higher at 125° and 135° than at 145° (p < 0.001)
- Center of force shifted caudally with increasing flexion — especially in medial meniscus
- Lateral meniscus peak pressure was significantly higher at 125° than 145° (p = 0.049)
- Mean pressures on lateral meniscus decreased with extension, while medial meniscus pressure remained constant
- Relevance: Helps interpret meniscal load in early cruciate disease and in surgical modeling

In Bower 2025 et al., on radial diaphyseal exposure, which statement best describes the comparison between craniomedial and craniolateral approaches?
🔍 Key Findings
- Craniomedial and craniolateral approaches provided comparable exposure of the feline radial diaphysis (p > .05).
- Mean exposed surface area was slightly greater with the craniolateral approach, both including and excluding the supinator muscle, but differences were not significant.
- Elevation of the supinator muscle increased exposure for both approaches.
- Cadaver weight and limb side did not significantly affect exposure area.
- The craniolateral approach allows easier patient positioning in lateral recumbency without traction or an assistant.
- Craniolateral access facilitates dual bone fixation (radius and ulna) through a single approach.
- The craniomedial approach carries greater risk to median and radial nerves during muscle elevation.
- Findings validate the craniolateral approach as a practical alternative for feline antebrachial fracture repair.

In Monti 2025 et al., on lymph node fluorescence imaging, what was the observed postoperative complication rate following laparoscopic ISLN removal using NIRF-ICG?
🔍 Key Findings
- Laparoscopic ISLN removal using NIRF-ICG was feasible in 89% of dogs (16/18), demonstrating high procedural success with minimal invasiveness.
- Median laparoscopic dissection time was only 12 minutes, suggesting efficiency of the NIRF-guided approach.
- No postoperative complications were observed, and intraoperative complications occurred in only 2 dogs (11.1%), both requiring conversion to open surgery.
- Metastatic disease was confirmed in 48% of patients (12/25 nodes), including cases where LNs appeared normal in size, highlighting the value of histologic evaluation.
- NIRF-ICG enabled precise identification of small and mildly enlarged nodes, which are often missed during traditional imaging or palpation.
- Fluorescent dye leakage following LN capsule rupture limited visibility and required surgical conversion, indicating a key limitation of the technique.
- ICG signal was occasionally absent in metastatic LNs, likely due to lymphatic rerouting or obstruction, underscoring limitations in SLN identification.
- The lateral approach allowed consistent access to ipsilateral MILN, IILN, and sacral LNs, though contralateral nodes were inaccessible with this method.
