In Carvajal 2025 et al., on femoral stem breakage, what was the most common radiographic finding among failed implants?
🔍 Key Findings
Incidence of BFX lateral bolt stem breakage: 2.95% (13 dogs, 14 stems)
Implant factors:
- 13/14 were BFX lateral bolt stems (sizes #5–7)
- +9 necks used in 5/11 of 17 mm heads
- 10/14 stems undersized based on radiographs
- 10/13 dogs exceeded weight limits for implanted stem size
Malalignment:
- 10/14 had varus alignment (median 3.9°)
- 8/14 had insufficient proximodistal seating
Breakage site: Proximolateral shoulder in all cases
Revision outcomes:
- 11 revised (7 CFX, 3 larger BFX, 1 collared)
- 9/10 revised dogs regained full function
- Complications: 1 rebreakage, 1 periprosthetic fracture, 1 fixation failure
Histopathology:
- Electron microscopy showed fatigue striations and incomplete bead fusion
Conclusion: Avoid small BFX lateral bolt stems if undersized or if long necks required; use weight guidelines to prevent fatigue failure.

In Banse 2022 et al., on skill retention methods, what likely explained the temporary reversal in skill scores one day post-training in LMU MI students?
🔍 Key Findings
- Spaced instruction (SI) improved immediate performance on the first learned skill compared to massed instruction (MI) in both LSU and LMU cohorts.
- Cognitive load was higher in MI students at LMU, particularly in physical demand, effort, and frustration, while LSU showed no significant cognitive load differences.
- Skill performance differences disappeared after 2 weeks of supervised practice, regardless of instructional format.
- Time to complete skills improved over time, but this did not always correlate with improved checklist or global rating scores.
- Intrinsic cognitive load increased when teaching more complex or related surgical tasks in the same session.
- Initial skill complexity and prior exposure may influence effectiveness of spaced vs massed instruction.
- Supervised practice sessions are critical to eliminate initial skill disparities between instructional methods.
- Massed instruction may still be acceptable if followed by scheduled practice opportunities.

🔍 Key Findings Summary
- Design: Prospective, randomized, double-blinded controlled trial
- Population: 32 brachycephalic dogs undergoing cut-and-sew sharp staphylectomy
- Groups: Adrenaline + lidocaine (Group A) vs. Lidocaine only (Group NA)
- Main Findings:
- Total hemorrhage significantly lower in Group A (median 1.82 g) vs Group NA (7.95 g); p = .013
- Normalized hemorrhage significantly lower in Group A; p = .021
- Surgeon-assigned hemorrhage scores significantly lower in Group A; p = .029
- No adverse effects (tachycardia, hypertension, arrhythmia, etc.) noted from adrenaline use
- Breed effect: English Bulldogs bled more overall even after normalization
- Clinical Implication: Adrenaline in nerve blocks reduces hemorrhage without added risk

In Santos 2025 et al., on feline MPL morphology, what is the clinical implication regarding femoral or tibial corrective osteotomies?
🔍 Key Findings
Sample: 21 cats (10 control, 11 affected); 14 normal limbs vs 18 with MPL (MPL II: 7, MPL III: 11).
Significantly different CT measurements in MPL vs control:
- aLDFA: MPL II > control and MPL III (p = 0.014)
- FTW: MPL III > control (p = 0.021)
- FTD: control > MPL II and III (p < 0.001)
- TTA: MPL II and III had increased external tibial torsion vs control (p < 0.001)
- fPL and PV: MPL III cats had longer and more voluminous patellae
No significant differences in AA, mMPTA, TTD, fPW, aPH.
Patella width exceeded trochlear width in all groups.
Authors suggest femoral and tibial angular correction may not be indicated in most feline MPL II–III cases.
Soft tissue techniques and trochleoplasty warrant further investigation.
CT method: Intraobserver ICC good in 64%, interobserver poor in 36% of metrics.

In Almeida 2025 et al., on TPLO and partial CCL rupture, where was the greatest increase in ligament thickness observed postoperatively?
🔍 Key Findings
- Transecting the CCL remnant during TPLO did not reduce patellar ligament thickening (PLT) at any measured point (proximal, mid, distal).
- Transection also failed to reduce postoperative patellar ligament shortening (PLL) at 6 weeks.
- Both groups (transected vs non-transected) showed significant thickening and shortening, with greatest PLT increase at the midpoint.
- Increased PLT was positively correlated with tibial plateau rotation (p = 0.02) and postoperative TPA (p = 0.04).
- No correlation between TT-O (tibial tuberosity width index) and PLT, suggesting narrow osteotomies did not influence PLT in this population.
- Partial CCL rupture was not significantly protective; dogs with partial tears still developed ligament thickening.
- Post-TPLO mid-patellar ligament thickening may relate to Gelpi retractor placement and osteotomy mechanics rather than CCL status.
- Authors do not recommend CCL transection during TPLO to prevent desmitis, citing possible increased instability and degeneration.

In Miyagi 2025 et al., on endoscopic laser sphincterotomy, what defined the transition between the intramural and extramural common bile duct (CBD)?
🔍 Key Findings
- Endoscopic-assisted retrograde catheterization (EARC) and laser sphincterotomy were successful in 18/18 cadavers, demonstrating technical feasibility.
- Intramural common bile duct (ICBD) length ranged from 10 to 21 mm (mean 15.8 mm), with no correlation to body weight (r = 0.06, p = .79).
- Transition from ICBD to extramural duct was accurately identified endoscopically in 88% (16/18); transition was heralded by separation of the submucosal layer.
- Partial lateral perforations occurred in 2/18 dogs, only during early learning phase; no leakage was found on open dissection.
- Laser sphincterotomy preserved the pancreatic duct orifice, aided by protective catheter positioning.
- Compared to open duodenotomy, this technique allows for a smaller incision and less manipulation of the pancreas, which may reduce morbidity.
- No adverse events such as intra-abdominal saline egress or full-thickness perforation occurred, and the technique allowed safe access up to 10 mm from the MDP.
- Cadaveric limitations included absence of biliary pathology and inability to evaluate live complications, but the technique shows promise for future live animal trials.

In Buote 2023 et al., on laparoscopic sleeve gastrectomy in cats, what technique helped avoid staple line misplacement near the lesser curvature?
🔍 Key Findings
- LVSG was feasible in 9/10 feline cadavers and both live cats, with no intra- or postoperative complications in live cases.
- Two cadavers developed suspected stenosis due to staple lines too close to the lesser curvature; avoided with orogastric tube placement in later cases.
- No evidence of gastric leakage in any cadavers (8/10 tested) or live patients after methylene blue leak tests.
- Mean surgical time was ~110 min cadavers / 115 min live, and 27.6% of stomach mass was resected.
- Both live cats recovered uneventfully, lost 21–24% body weight over 3 months, and had no GI complications at 6-month follow-up.
- Orogastric tube and tension on the greater curvature were critical to avoid staple line misplacement or stenosis.
- No oversew of the staple line was needed, and unreinforced staples showed no leakage in live patients.
- Future studies needed to assess metabolic outcomes and ideal staple sizing and closure techniques.

In Sabol 2024 et al., what technique was recommended to reduce risk of implant misplacement?
🔍 Key Findings Summary
- Evaluated ideal dorsolateral implant trajectories in T1–T13 using CT in 30 dogs across five weight classes.
- Corridor widths were narrowest in the mid-thoracic vertebrae (as little as 1.8 mm) and increased cranially and caudally.
- Allowable deviation angles (ADA) were often very small (as little as 3°), indicating high risk for canal or thoracic structure breach.
- Distances to critical structures (lungs, aorta, subclavian artery, azygos vein) were often <1 mm, even in large dogs.
- Data suggest extreme caution and precision are needed for thoracic vertebral implant placement and support use of navigation or 3D-printed guides.

In Katz 2022 et al., on meniscal flounce sign, which of the following was recommended despite the flounce sign's diagnostic value?
🔍 Key Findings
- A positive meniscal flounce sign was associated with normal menisci in 95.5% of cases, demonstrating strong predictive value.
- Absence of the meniscal flounce sign was associated with meniscal tears in 92.7% of cases.
- Overall diagnostic accuracy of the flounce sign was 94.6%, with 96.6% sensitivity and 90.5% specificity.
- Most tears in flounce-negative stifles were bucket-handle tears (73.8%), while radial tears were present in some flounce-positive stifles.
- Radial tears did not consistently eliminate the flounce sign, suggesting they may not disrupt meniscal fiber tension sufficiently.
- All procedures were arthroscopically performed, with probing and visualization of the medial meniscus' caudal pole.
- Flounce sign should complement, not replace, probing—especially as some tear types (e.g., radial) may not abolish the sign.
- Limb positioning and joint distraction may affect flounce visibility, introducing minor observer variability.

In Fracka 2023 et al., on patient-specific guides, what was a notable advantage of PSGs during surgery?
🔍 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.
