In Schneider 2025 et al., on axillary LN extirpation, what percentage of removed axillary lymph nodes contained tumor-related pathology?
🔍 Key Findings
- Lateral approach to ALN extirpation was successful in 100% of cases (44 dogs, 48 ALNs) with consistent anatomical landmarks (costochondral junction of rib 1 and caudal scapular edge).
- Median time for ALN removal was 16.6 minutes, highlighting a fast and efficient dissection method.
- No intraoperative complications were recorded (e.g., hemorrhage or inability to find the lymph node).
- Postoperative complications occurred in 18% of cases, including seromas (n=2), wound dehiscence (n=4), lameness (n=1), and discomfort (n=1).
- Histopathology revealed 56% of ALNs had tumor-related pathology, including overt metastases, early metastasis (HN2), or premetastatic changes (HN1).
- Normal-sized ALNs (<2 cm) still harbored metastases in 22% of cases, emphasizing the unreliability of size as a staging criterion.
- False negatives in cytology occurred in 4 cases, underlining the limitations of cytologic evaluation for staging.
- The technique was reproducible without specialized tools, suggesting wide applicability in general and referral practice.

In Israel 2022 et al., on cerclage wire in THR, which complication did occur postoperatively despite cerclage placement?
🔍 Key Findings
- No proximal femoral fractures occurred in any of the 184 hips with cerclage wire placement
- Cerclage wire was well tolerated, with no failures or complications related to the wire
- Application of a single cerclage wire took <10 minutes, was cost-effective, and required minimal instrumentation
- 3 postoperative complications (1 fissure, 2 fractures) occurred distal to the cerclage site, near the stem tip, requiring plate/screw fixation
- All dogs returned to normal activity, and all owners were satisfied with the outcome
- Cerclage placement location is critical—must be proximal to the lesser trochanter and close to the calcar to resist hoop strain
- Biomechanical evidence supports that cerclage wires improve resistance to hoop strain and subsidence of cementless stems
- Press-fit cementless stems may settle, but when supported by cerclage, this does not result in fractures even in undersized implants

In Miller 2024 et al., on SOP-LC mechanical testing, which configuration improved initial torsional stiffness?
🔍 Key Findings Summary
- No significant difference in mechanical properties between contoured vs non-contoured SOP-LC rods
- Clamp configuration significantly influenced mechanical performance:
- Single-side clamps → ↑ yield load, ↑ displacement, ↑ bending strength (p < 0.05)
- Alternating-side clamps → ↑ initial torsional stiffness (p = 0.029)
- Clamp slippage was evident only in torsional tests; screw loosening may be torque-dependent
- Mild screw bending and construct offset suggest subtle instability
- Recommends clamp configuration choice based on loading scenario
- Suggests 3.0 Nm torque may be more effective than 2.5 Nm to prevent clamp slippage

In Niida 2024 et al., on surgical residents and TPLO time, what data did the study provide on complication rates?
🔍 Key Findings
- Resident involvement significantly increased TPLO surgery duration compared to cases performed by faculty surgeons (FS)-only. Residents required 54% more surgery time (GLSM, 153 min) than FS-only cases (GLSM, 99 min), representing a 1.54-fold increase.
- The study did not report on short-term complication rates. No conclusions can be drawn from this source regarding complications between resident and faculty groups.
- Bone plate contouring was not evaluated. The source does not provide data regarding contouring frequency or its comparison between groups.
- Surgery duration significantly decreased after the first year of residency, but remained stable between second- and third-year residents. This was largely due to shorter tibial osteotomy durations, while arthroscopy times remained unchanged across residency years.
- Meniscal treatment was performed in 80% of cases, and it was associated with increased surgical duration, but the study did not compare the frequency of medial meniscal release between resident and faculty cases.
- The study did not evaluate osteotomy healing or revision surgery. Cases requiring immediate reoperation were excluded.
- Bone union outcomes were not assessed at 8 weeks or any other time point.
- The study concludes that resident participation significantly prolongs surgical time, but no data are provided regarding the effect on short-term clinical outcomes.

In Brisimi 2022 et al., on tracheal anastomosis tension, where did failure most commonly occur?
🔍 Key Findings
- Tracheal anastomoses in immature dogs failed at significantly lower distraction forces (44.91 ± 59.03 N) than in adults (149.31 ± 45.36 N; _P_ = .007).
- Immature tracheae tolerated significantly more elongation before failure (39.75 ± 5.45%) than adult tracheae (30.57 ± 7.19%; _P_ = .0012).
- All constructs failed by suture tearing through the annular ligament, primarily near the dorsal tracheal ring.
- Overlapping of tracheal ends was seen in 50% of specimens across both age groups, suggesting limitations in tissue apposition with the chosen technique.
- Simple continuous pattern using 2-0 polypropylene was used; this pattern provides superior tensile strength compared to simple interrupted, but apposition may be suboptimal.
- Tracheal elasticity in immature dogs may allow longer resections, but the lower tensile strength necessitates reinforcement.
- Annular ligament-cartilage technique with 4-mm suture spacing showed variable results; smaller bites and nylon suture may improve outcomes.
- Ex vivo setup using frozen-thawed tracheae is a limitation, but prior studies support comparability with fresh tissue.

In Rodiño Tilve 2022 et al., on feline THR outcomes, which implant feature was associated with all luxation complications?
🔍 Key Findings
From “Long-term follow up of 44 cats undergoing total hip replacement” by Rodiño Tilve et al.
- Slipped capital femoral epiphysis (SCFE) was the most common surgical indication (61%, 34/56 hips), primarily affecting young neutered male cats.
- All THRs used cemented micro/nano BioMedtrix implants; most common femoral stem was size #3, and most common acetabular cup was 12 mm.
- Postoperative complication rate was 19.6% (11/56) with 9 major complications (luxation most common), and no intraoperative complications reported.
- All luxations occurred in hips implanted with femoral neck +0 mm length implants.
- Second luxations were more common when revision used same implant size; use of larger implants reduced reluxation rates.
- FMPI-sf score improved significantly from median 2.111 pre-op to 0.111 post-op (P < .001), indicating reduced pain and improved function.
- Very high owner satisfaction: 91% (30/33) reported outcome as "very good."
- No significant associations found between complications and variables like weight, sex, implant size, or surgical indication.

In Nash 2024 et al., on esophageal pH monitoring, what was the defined upper reference limit for distal GER events per hour in healthy nonbrachycephalic dogs?
🔍 Key Findings
- Esophageal pH-monitoring was well tolerated in all 35 nonbrachycephalic dogs, with no major adverse events reported.
- Distal GER occurred in 80% of dogs, but events were typically brief and non-productive; proximal GER occurred in only 39%.
- Upper reference limits for GER were 2.4 events/hour (distal) and 0.4 events/hour (proximal).
- Cumulative acid exposure was minimal: upper limits were 2.3% (distal) and 0% (proximal).
- Comparison with brachycephalic dogs shows significantly higher GER frequency and duration, validating the diagnostic utility of pH monitoring.
- Transnasal probe placement under light anesthesia was safe and less morbid compared to percutaneous or conscious techniques.
- No expelled or productive regurgitation occurred, despite some GER events, indicating efficient esophageal clearance in healthy dogs.
- Diet and fasting duration may affect GER, but these were not controlled variables in this study.

In Meltzer 2022 et al., on femoral implant selection, which statement best describes the complication rate among dogs undergoing total hip replacement?
🔍 Key Findings
- Hybrid implants were used in older, heavier dogs with lower canal flare index (CFI) compared to cementless types.
- CFI <1.8 was associated with higher risk of femoral fracture or stem subsidence with cementless implants.
- Total complication rate was 14%, with catastrophic complications in only 1.5%—lower than reported in other studies.
- No significant difference in complication rates across implant types (BFX, BFX-C, hybrid).
- Femur fractures were rare (2.9%), lower than in prior studies, and successfully managed with cerclage/plate fixation.
- Coxofemoral luxation was the most common complication (8 cases); all occurred within 62 days post-op, mostly resolved with revision.
- Collared BFX stems did not significantly reduce complications, though they may limit stem subsidence.
- An implant selection algorithm was proposed, using age ≥7 years, weight ≥45 kg, and CFI <1.8 to guide cemented vs. cementless stem use.
