In Burkhardt 2024 et al., on coagulation testing in liver lobectomy, dogs with both PT and aPTT prolongation were how much more likely to undergo emergency surgery?
🔍 Key Findings
- 20.6% of dogs had a preoperative prolongation in PT or aPTT, but only 5.6% had both prolonged.
- Hemangiosarcoma was the only tumor type significantly associated with both PT and aPTT prolongation (37.5% of hemangiosarcoma cases, p < .001).
- Dogs with both PT and aPTT prolongations were 6.5× more likely to have emergency surgery (p < .001) and 2.5× more likely to have hemoabdomen (p = .0022).
- 60% of dogs with both PT and aPTT prolongation required blood transfusion (p < .001).
- Only 1.9% of all dogs had both PT and aPTT prolonged by >25%, suggesting limited clinical utility of routine PT/aPTT testing.
- Platelet count <50,000/μL was rare (1.5%) and not associated with PT/aPTT changes or transfusions.
- Routine PT/aPTT testing offers low diagnostic yield in elective liver lobectomy cases.
- Authors recommend case-by-case PT/aPTT screening, especially when hemangiosarcoma or bleeding tendencies are suspected.

In Scheuermann 2024 et al., on 3D-printed reduction systems, what was the most significant intraoperative imaging difference between 3D-MIPO and c-MIPO groups?
🔍 Key Findings
- The study was a historic case-control trial comparing custom 3D-printed VSP-guided MIPO (3D-MIPO) to conventional MIPO (c-MIPO) in dogs with diaphyseal tibial fractures.
- Surgical time was significantly shorter in the 3D-MIPO group (117 min vs. 151 min; p = .014), and fluoroscopy use was dramatically reduced (11 vs. 37 images; p < .001).
- All 3D-MIPO reductions were acceptable or near-anatomic; 2 c-MIPO dogs had unacceptable reductions.
- Tibial length, frontal, and sagittal alignment post-op were similar between groups; no significant difference in anatomic restoration (p > .1).
- Radiographic union occurred in all dogs by 3 months. Time to union was similar between groups (3D-MIPO: 67 days vs. c-MIPO: 53 days; p = .207).
- Postoperative complication rate was higher in 3D-MIPO (27% vs. 14%), including 2 major infections requiring implant removal.
- 3D-MIPO required more pre-op time (~23 hours longer from presentation to surgery; p = .002), partly due to guide printing/sterilization.
- Improved surgical efficiency and more consistent reductions were noted in the 3D-MIPO group, supporting its clinical utility despite increased pre-op logistics.

In Lotsikas 2025 et al., on stifle distraction portal, what was the most frequently affected cartilage zone in terms of iatrogenic damage?
🔍 Key Findings
Study type: Cadaveric stifle arthroscopy in large breed dogs (n=12 joints from 6 dogs)
Goal: Describe and assess the proximal lateral portal for insertion of a Ventura stifle thrust lever (VSTL)
Main results:
- No damage to the long digital extensor tendon (LDE) with this portal
- VSTL could be placed without removing the arthroscope
- Portal creation time ~37 seconds (faster than previously reported)
Cartilage impact:
- Superficial iatrogenic articular cartilage injury (IACI) present in all specimens
- No difference in IACI between 5- and 10-minute lever durations
- Zone 4 (lateral femoral condyle) had significantly more damage than zones 1–3 (p < .05)
Conclusion: Portal was safe, repeatable, minimally invasive, and did not increase cartilage damage with up to 10-minute lever use

In Berthomé 2025 et al., on prophylactic fenestration in cervical IVDE, what was a statistically significant outcome regarding surgery duration?
🔍 Key Findings
- Prophylactic fenestration (PF) significantly reduced recurrence of cervical intervertebral disc extrusion (0% vs. 37.8%, p < .001).
- Surgery time was longer with PF (median 182 vs. 110 min, p = .017), but no difference in perioperative complication rates (PF 16.7%, non-PF 18.9%; p = .838).
- 25% overall recurrence rate, but all recurrences occurred in the non-PF group.
- Medical management was effective in 92.9% of recurrence cases.
- Most PF sites targeted adjacent discs; 88.9% were at adjacent levels, which are common recurrence sites.
- Neurologic outcomes were similar between PF and non-PF dogs post-surgery and at follow-up.
- Fenestration technique (blade vs. burr) not shown to affect outcome but contributed to extended surgical time.
- No major complications or deaths linked directly to PF in initial surgeries.

In Caldeira 2025 et al., on femoral neck fixation, what was the main mechanical advantage of using three cannulated screws over two?
🔍 Key Findings
Design: In vitro study on cadaveric femurs (n=21) with basilar femoral neck fractures stabilized using 2 vs 3 titanium cannulated screws.
Stiffness: Control > 3-screw > 2-screw (674 > 120 > 90 N/mm).
Yield Load: 3-screw (586 N) > 2-screw (303 N); both < intact femur (2692 N).
Displacement: No difference across groups.
Complication: 3-screw technique more demanding; higher risk of cortical perforation, especially with narrow femoral necks.
Failure Mode: Dislodgement of femoral head + screw shaft bending.
Conclusion: 3 screws = stronger construct than 2 screws. Clinical implications need further study.

In Longo 2023 et al., on CT trochlear measurements, what difference in FTGA was observed between small and medium/large breed dogs without MPL?
🔍 Key Findings
- Dogs with MPL had significantly shallower femoral trochlear grooves compared to controls, based on CT-measured femoral trochlear groove angle (FTGA).
- FTGA >134° in small breeds (SB) and >128° in medium/large breeds (MLB) were associated with MPL and can serve as surgical thresholds for considering trochleoplasty.
- FTA and FTRIA measurements were less reliable, showing lower sensitivity/specificity than FTGA.
- Inter-rater reliability for FTGA was excellent (ICC > 0.9), supporting its use in clinical decision-making.
- FTGA differed significantly between SB and MLB dogs, suggesting anatomical variation influences MPL predisposition.
- Dogs with MPL but with FTGA below threshold may not benefit from trochleoplasty, supporting individualized surgical planning.
- CT provides more precise and reproducible evaluation of trochlear morphology than radiography or ultrasound.
- The study introduces a CT protocol using P25 and P50 reference points for consistent FTGA measurement.

In Adair 2023 et al., on PCCLm vs. open cystotomy, what was a statistically significant long-term difference in outcomes?
🔍 Key Findings
- PCCLm resulted in significantly fewer postoperative lower urinary tract signs compared to OC (13.0% vs 60.9%, p <.001).
- Incomplete urolith removal was not significantly different between PCCLm and OC (11.4% vs 20%, p = .112).
- PCCLm had significantly shorter anesthesia times than OC when no concurrent procedures were performed (97.5 vs 120 min, p < .001).
- Surgical site infection/inflammation (SSII) rates were low and not significantly different between groups (4.5% PCCLm vs 1.8% OC).
- Dogs undergoing PCCLm were more frequently discharged same-day (84.7% vs 0% in OC), reflecting faster recovery.
- PCCLm had higher intraoperative complication rates (22.1% vs 3.4%), mostly due to incision extension or conversions.
- Time to additional surgery for urolith recurrence was longer in PCCLm dogs (24 vs 11.5 months, p = .004).
- Calcium oxalate uroliths were more prevalent in PCCLm cases, while OC had more struvite or mixed types.
