In Miller 2025 et al., on spinal drill guide accuracy, what was the Zdichavski classification for all screw placements?
🔍 Key Findings
- 3D-printed, SOP plate-specific guides enabled safe screw placement from T12–L5 in canine cadavers and models.
- All 140 screw trajectories were classified as Zdichavski Grade 1, indicating optimal placement without vertebral canal breach.
- Screw angles (cranial-caudal and transverse) matched preoperative planning, with no significant deviation.
- Entry/exit point deviations were <1 mm on average, deemed clinically negligible.
- Drill guides were quick to place (<30 sec per vertebra) and improved ease of surgery.
- Plates acted as effective reduction tools, guiding alignment during screw placement in mobile spines.
- Minor technical challenges arose from cadaveric spine mobility, mitigated by sequential screw insertion.
- Technique may enable future use in fracture/luxation reduction, pending further cadaveric and clinical trials.

In Ibrahim 2022 et al., on scrotal arterial supply, what was concluded regarding the use of scrotal flaps in neutered dogs?
🔍 Key Findings
- Dorsal scrotal arteries, branching from the ventral perineal arteries, are the dominant arterial supply to the scrotum in dogs.
- The ventral scrotal arteries, arising from the external pudendal arteries, perfused only the cranial scrotal border and were inconsistently present or absent in some dogs.
- A scrotal flap based on the dorsal scrotal arteries showed strong perfusion and may be a viable axial pattern flap.
- Perfusion was consistent across fresh and frozen cadavers, showing no difference due to preservation method.
- Poor flap survival (27%) occurred when based on cranial supply alone (i.e., ventral scrotal arteries), confirming importance of preserving caudal supply.
- There are anastomoses between dorsal and ventral scrotal arteries, offering collateral flow but insufficient alone for complete perfusion.
- Scrotal flaps based on the caudal pedicle may be applicable for reconstruction of proximal medial/lateral thigh wounds.
- Proposed flap requires careful preservation of ventral perineal arteries, ideally designed 2.5–3 cm lateral to midline in large dogs.

In Kwok 2023 et al., on BFX lateral bolt THR in dogs, which type of complication most often led to prosthesis explantation?
🔍 Key Findings
- 97.4% of dogs returned to normal function after total hip replacement using the BFX lateral bolt.
- Mean femoral stem subsidence was 1.22 mm, with most occurring in the first month and minimal thereafter.
- Postoperative complication rate was 13.6%, with 9.2% major and 4.4% minor complications.
- Femoral fractures (3.6%) and coxofemoral luxations (3.6%) were the most common major complications.
- Increased age and higher stem size were risk factors for postoperative femoral fractures; CFI >2.0 was also associated.
- Medial calcar fractures were avoided, and fractures occurred distal to stem ingrowth zone, simplifying repairs.
- Three cases underwent prophylactic plating, all with excellent outcomes and no complications.
- Explant rate was 2.6% (5/195), with most failures involving acetabular cup rather than femoral stem.

In Adair 2023 et al., on PCCLm vs. open cystotomy, what factor increased the odds of surgical site infection/inflammation in the PCCLm group?
🔍 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.

In Israel 2022 et al., on cerclage wire in THR, what is a biomechanical benefit of cerclage application around the proximal femur?
🔍 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 Parlier 2024 et al., on insufflation effects on portal pressure in dogs, what insufflation pressure was predicted to induce portal hypertension (>15 mmHg)?
🔍 Key Findings
- Portal pressure increased proportionally with insufflation pressure: 38% at 6 mmHg, 95% at 10 mmHg, and 175% at 14 mmHg.
- Exponential model: average increase of 7.45% per mmHg of insufflation pressure (CI: 4.7–10.2%).
- No systemic hemodynamic adverse effects were observed; MAP remained >60 mmHg throughout.
- Portal hypertension threshold (15 mmHg) predicted at ~6.4 mmHg insufflation pressure.
- No statistical impact from patient weight, pressure-to-weight ratio, or order of insufflation rounds.
- Measurement technique was feasible and safe, with only minor challenges (e.g., catheter kinking).
- The study supports use of the lowest insufflation pressure needed for visualization to avoid portal hypertension.
- Baseline portal pressures returned after desufflation, supporting comparison pre- and post-attenuation.

In Kuvaldina 2023 et al., on endoscopic axillary lymphadenectomy, what was the typical surgical time for axillary node removal in cadavers?
🔍 Key Findings
- Endoscopic excisional biopsy of axillary lymph nodes was successfully performed in cadavers and clinical dogs with minimal complications.
- The technique used a SILS port and CO₂ insufflation through a small incision between the latissimus dorsi and superficial pectorals.
- In 4 cadavers (6 limbs), mean time to remove axillary nodes was 33 minutes, and single nodes were found in 5/6 limbs.
- In 3 clinical dogs, the procedure was successful in 2 cases; 1 required conversion to open surgery due to difficulty manipulating the node.
- Accessory axillary nodes were successfully excised when present, located adherent to deep latissimus dorsi.
- No cases developed lymphedema, pneumothorax, or major complications postoperatively.
- Subjective benefits included better visualization, reduced dissection, and less postoperative morbidity than open techniques.
- Study suggests MIS lymphadenectomy may improve staging accuracy and reduce complications, though larger studies are needed.

In Jenkins 2022 et al., on medial epicondylar fissure fracture, what was the general clinical outcome for cases with MEFF during the perioperative period?
🔍 Key Findings
- MEFF occurred in 11.4% (10/88 elbows) following medial-to-lateral transcondylar screw placement in dogs with HIF.
- Screw size to condylar height ratio >41% significantly increased MEFF risk (P = .004, OR 1.52).
- MEFF was not recognized intraoperatively in 60% of cases and was only seen on follow-up or retrospective imaging review.
- Screw loosening was the most common complication (11.2%), observed both with and without MEFF.
- MEFF tended to increase the risk of screw loosening (P = .06), but was not statistically significant.
- Most MEFFs did not require treatment and healed radiographically by 14–17 weeks in monitored cases.
- Shaft screws were used in all MEFF cases, but shaft vs cortical design was not significantly associated with MEFF.
- The clinical impact of MEFF was minor in most cases, although long-term significance is unknown.
