In Monti 2025 et al., on lymph node fluorescence imaging, which factor was identified as a limitation of ICG uptake for sentinel lymph node identification?
🔍 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.

In Azuma 2024 et al., on 3D vs 2D laparoscopy, which group might benefit most from 3D laparoscopy based on the study’s discussion?
🔍 Key Findings
- 3D laparoscopy significantly reduced time to first endoclip placement compared to 2D (median 76 vs. 238 seconds, p = .016).
- Total surgical time was not significantly different between 3D and 2D groups.
- No differences were observed in intraoperative complications such as cystic duct injury, clip dislodgment, or gallbladder perforation.
- Cystic duct stump length was comparable between groups (median 2.5 mm).
- Liver parenchyma attachment severity did not differ significantly between 2D and 3D groups.
- All procedures were performed by an experienced surgeon, potentially reducing the benefit seen with 3D visualization.
- No conversions to open surgery occurred, and no intraoperative complications were reported.
- The study suggests 3D laparoscopy may aid less experienced surgeons due to enhanced depth perception.

In Nagahiro 2023 et al., on quadriceps-femoral mismatch, what was the primary clinical implication of a reduced QML/FL ratio in dogs with MPL?
🔍 Key Findings
- Quadriceps muscle length/femoral length ratio (QML/FL) was significantly lower in dogs with grade IV MPL than grades I–III (p ≤ .002).
- Shortened QML was associated with increased femoral torsion angle (FTA) and increased aLDFA, indicating correlation with femoral deformity.
- QML/FL increased with age, possibly due to muscular development or reduced deformity in older dogs (p = .004).
- Grade IV MPL dogs had QML/FL < 0.87, the lower normal limit based on healthy beagles, suggesting clinically significant muscle shortening.
- PLL/PL ratio (used to diagnose patella alta) was not associated with QML/FL or MPL severity in small breeds.
- QML/FL can help preoperatively identify candidates for femoral shortening ostectomy, improving femoropatellar alignment.
- Multivariate regression model confirmed QML/FL is independently influenced by age, FTA, and aLDFA (R² = 0.45).
- CT-based 3D measurements enabled objective, noninvasive quantification of femoral and muscle alignment parameters.

In Dalton 2023 et al., on acetabular fracture repair, how did the clinical case dog recover following minimally invasive acetabular fracture repair?
🔍 Key Findings
- Minimally invasive repair of acetabular fractures using precontoured plates on 3D-printed models is feasible and technically reproducible in dogs.
- All cadavers had fracture gaps <2 mm and step defects <1 mm, indicating accurate reduction.
- Sciatic nerve injury was minimal or absent in all cases, supporting potential neuroprotection from indirect approaches.
- Pelvic angulation was maintained <5°, confirming preservation of alignment post-reduction.
- Surgical time averaged ~46 minutes in cadavers for both approaches and repair.
- Clinical case showed good radiographic healing by 8 weeks and full union by 3 months, with early weight-bearing post-op.
- Use of locking screws improved reduction fidelity, particularly across a broad plate span.
- 3D printing accelerated surgical planning, though its necessity remains debated due to the availability and cost concerns.

In Scott 2023 et al., on thoracoscopic-assisted lung lobectomy, what was the **most common classification** of postoperative complications?
🔍 Key Findings
- TA lung lobectomy was feasible in dogs ≥3 kg, including those with lesions up to 10 cm.
- 12 intraoperative complications (40%) occurred, with 6 dogs (20%) converted to open thoracotomy, mainly due to adhesions or inability to isolate lobes.
- Postoperative complications occurred in 8 dogs (27%), most were mild (63%), and only 1 death (3%) was reported.
- Median hospitalization was 47 hours; 29/30 dogs were discharged successfully.
- One-lung ventilation (OLV) was attempted in 7 dogs but successfully maintained in only 4.
- Linear staplers had shorter surgery times (median 57.5 min) than endoscopic staplers (80 min).
- Histopathology confirmed neoplasia in 77% of cases, most commonly papillary and bronchioalveolar carcinoma.
- TA lobectomy allows MIS in smaller dogs or with large lesions, avoiding need for full thoracotomy or complex anesthesia/stapling.

In de Moya 2023 et al., on FGPP of femoral capital physeal/neck fractures, what was the most common preoperative fracture displacement classification?
🔍 Key Findings
- 11 dogs, 13 fractures (mostly Salter-Harris type I) were repaired with FGPP using Kirschner wires.
- 10/13 fractures achieved satisfactory healing with good limb function at ~43 days median follow-up.
- Major complications occurred in 5 dogs: intra-articular pin placement, implant migration (2), implant failure with nonunion, and malunion.
- 2 dogs presenting >15 days post-injury with radiographic remodeling were poor candidates → higher risk of nonunion/malunion.
- Preoperative displacement was mostly mild (10/13 fractures); these had better outcomes than chronic or severely displaced cases.
- Median surgical time: 60 minutes (range 45–75), all performed percutaneously without conversion to open.
- Elective pin removal was performed in 5 cases; migration occurred with both short and long cut wires.
- Femoral neck resorption (“apple-coring”) was rare (2/10 healed cases) and thought to be less frequent than after ORIF due to reduced vascular disruption.

🔍 Key Findings Summary
- Study Design: Retrospective study of 100 radiographs using in silico and clinical data
- Mean preoperative TPA: 28.6°, higher in small dogs than large (p = .02)
- Mean planned TPA (in silico): 7.6°, not achieving 5° target (p < .01)
- Median postoperative TPA: 5.5° overall; higher in small dogs (7°) vs large (4.5°) (p = .06)
- Postoperative ostectomy position: More distal than recommended; average = 8.6 mm
- Increased distalization → greater under-correction of TPA (p = .01)
- Most accurate correction occurred when ostectomy was ≤7.5 mm from patellar tendon
- Wedge angle categories (TPA-Pre minus 5–2°) were used based on pre-op TPA

In Danielski 2022 et al., on humero-anconeal incongruity, what role did the novel caudo-medial arthroscope portal play in the study?
🔍 Key Findings
- A novel caudo-medial arthroscopic portal allowed visualization of previously undescribed cartilage lesions on the caudal medial humeral condyle.
- A consistent focal cartilage lesion (HA lesion) was observed in 100% of elbows with HIF (21/21), but in none of the 31 elbows without HIF.
- Lesions varied from indentations to full-thickness cartilage loss, typically elliptical and located just medial to the humeral condyle isthmus.
- A clunk-like sensation and dynamic engagement of the anconeal process into the lesion were observed in 16/21 elbows with HIF during elbow manipulation.
- In 5/21 elbows, engagement of the anconeal process led to observable widening of the HIF line, suggesting dynamic instability.
- Findings support a novel concept of humero-anconeal incongruity as a contributor to the pathogenesis of HIF.
- Spaniel breed was not a confounder—the lesion was only present in elbows with HIF, regardless of breed.
- The study suggests potential for using arthroscopy as a screening tool for early detection of humero-anconeal incongruity and HIF risk.

In Gomes 2025 et al., on subdural shunting for TL-AD, what was the guideline for selecting shunt tube size?
🔍 Key Findings
- Modified subdural shunt (SDS) placement was adapted from prior techniques using a hemilaminectomy approach and no suturing of the dura or shunt.
- Dogs receiving SDS had significantly better long-term outcomes (85.7% improved) compared to those with durotomy alone (41.7%).
- Recurrence rate was lower in the SDS group (14.3%) than control (41.7%), though not statistically significant.
- Most recurrences occurred in Pugs (5/7), suggesting a breed predisposition.
- Shunt size was limited to 25% of spinal cord diameter, typically 3–3.5 Fr.
- CSF flow through the shunt was confirmed intraoperatively, supporting the role of SDS in maintaining flow and possibly preventing recurrence.
- Immediate postoperative outcomes were not different between groups (≈42% deteriorated), but long-term recovery was better with SDS.
- Steroid use pre-surgery did not correlate with improved outcome; fewer SDS dogs received steroids pre-op.

In Fidelis 2025 et al., on suture eyelet geometry, what effect did **cyclic loading** have on maximum failure load (Fmax)?
🔍 Key Findings
- Raised eyelets caused more suture mid-section failures than embedded eyelets, suggesting wear or cutting against the anchor.
- No significant effect of cyclic loading on failure load (Fmax) was found for any anchor group.
- Anika anchor showed the least reduction in suture strength relative to the reference (eyebolt screw), indicating a favorable design.
- All sutures failed via suture breakage, not anchor pullout, indicating suture fatigue was the primary failure mode.
- Sutures in raised eyelets more often failed at the mid-section, while those in embedded eyelets failed at the knot.
- IMEX and Jorvet anchors showed significantly reduced Fmax compared to eyebolt screws.
- Loading direction and anchor design likely affect wear and ultimate failure, particularly in dynamic in vivo conditions.
- Future designs should aim for embedded, smooth eyelets that can accommodate larger suture sizes without increasing wear.
