🔍 Key Findings

• Fewer R1 margins (tumor on ink) were achieved in mast cell tumors (MCTs) when using 6–10 mm lateral margins versus 0–5 mm (7% vs. 55%; _P_ = .049).
• For soft tissue sarcomas (STSs), no benefit was seen in margin completeness between 0–5 mm vs. 6–10 mm lateral margins (41% vs. 43% R1).
• Overall R1 rates were 26% for MCTs and 42% for STSs following PNE.
• R scheme (“tumor on ink” = R1) had better interobserver agreement (83%) compared to ≤1 mm margin criteria (68% agreement).
• Complication rate was moderate (26%), but no surgeries required revision.
• Local recurrence/metastasis occurred in 14% of dogs, with 60% of those having R1 margins.
• Adjunctive therapy was considered clinically indicated in 46% of 0–5 mm margin cases vs. 24% of 6–10 mm cases.
• Histologic grade and tumor size were not predictive of margin completeness.

🔍 Key Findings

• Study Design: Canine cadaveric study comparing intercostal thoracotomy (ICT), median sternotomy (MS), and transdiaphragmatic with caudal median sternotomy (TDCM) for accessory lung lobectomy (ALL).
• Main Outcomes:
  • Exposure Area: TDCM (193.5 cm²) > MS (106.5 cm²) > ICT (73.5 cm²) (p = .01).
  • TDCM provided significantly greater exposure than MS (p = .02) and ICT (p = .02); MS > ICT (p = .04).
  • Surgical Time: No significant difference (p = .06).
  • Lobe Excision (% by weight/surface area): No significant difference between groups (p = .4).
  • Staple Line Leak: Leak at ≤40 cmH₂O in 2/4 ICT, 0/4 MS, 0/4 TDCM (p = .09).
• Complications:
  • 1/4 MS cases had iatrogenic damage to an adjacent lobe.
• Technical Insights:
  • TDCM approach allowed immediate visualization of all three parts of the right pulmonary ligament.
  • The TDCM approach offers improved access without requiring en bloc removal with the right caudal lobe.
• Conclusion: The TDCM approach provides improved exposure for ALL lobectomy with no increase in surgical time or complications relative to other approaches.

🔍 Key Findings

• AMA-based CCWO realigned the anatomical and mechanical axes in 82% of dogs >50 kg, with postoperative AMA angle of 0° in most cases.
• Surgical site infection (SSI) rate was only 0.5%, markedly lower than TPLO-reported rates in similar populations (up to 37.5%).
• All osteotomies achieved Grade 4 healing by 8 weeks, with no implant failures.
• AMA-based planning based on preoperative AMA and TPA allowed for better correction of proximal tibial angulation compared to TPLO in large dogs.
• Use of a double locking plate (DLP) fixation and Robert Jones bandage (RJB) contributed to improved mechanical stability and infection prevention.
• Dogs with AMA angle >3.4° (hyper-CCAPT) were 38% of the cohort, supporting AMA as a critical metric in planning.
• Postoperative alignment of the AA and MA was more consistently achieved when preoperative AMA was >2.4°, confirming suitability of AMA-based CCWO for severe angulation.
• Most infections in TPLOs occur within 15 days, but RJB plus antibiotics in this study appeared protective, suggesting benefit for early-phase SSI prevention.

🔍 Key Findings

The study included 162 deep-pain-negative dogs undergoing decompressive surgery (hemilaminectomy) for acute thoracolumbar intervertebral disc extrusion (IVDE).

Ambulatory recovery occurred in 53.1% of dogs (86/162).

The best performing machine-learning model was XGBoost, with an AUC of 0.9502 and accuracy of 89.1%, outperforming Ridge, AdaBoost, and Naive Bayes models.

Preoperative-only XGBoost models were less accurate, with AUC dropping to 0.8271 and accuracy to 71.9%.

Top predictive features (by SHAP analysis) included:

1. T2-weighted to L2 spinal cord signal ratio (lower values predicted better outcome)
2. Use of fenestration (presence associated with better recovery)
3. Hospitalization duration
4. Imaging modality used
5. Duration of nonambulatory status

Machine learning provided better insight into prognostic factors than traditional statistical methods.

🔍 Key Findings

Subject: 7-year-old Labrador underwent cementless total knee replacement (TKR) due to severe stifle OA.

Clinical function:

• Improved ROM from 90° pre-op to 120° post-op.

Wear evaluation:

• Mild UHMWPE insert wear, localized to caudal edges.

Histologic findings:

• Robust osseointegration at implant-bone interface.
• Fibrous tissue only in areas lacking porous coating.

Conclusion:

• Cementless TKR demonstrated excellent 6-year survival and functional outcomes.
• Support for considering early surgical intervention in severe stifle OA.

🔍 Key Findings

• Modified preputial urethrostomy without penile amputation was successfully performed in 4 male dogs with urethral stenosis or trauma.
• The technique involved anastomosis of the pelvic urethra to the preputial mucosa via caudal celiotomy, avoiding perineal urethrostomy complications.
• No cases of skin scalding or stoma stenosis were reported during short- and long-term follow-up.
• Two dogs developed mild urinary incontinence, particularly when excited; one improved with phenylpropanolamine.
• The approach preserved local anatomy, avoiding penile amputation, osteotomies, and preputial dissection.
• Postoperative urinary catheterization was used to protect the anastomosis, although optimal duration remains debated.
• Surgical access via the linea alba minimized tension at the anastomosis site and avoided complications from paramedian approaches.
• This technique may serve as a viable alternative to prepubic urethrostomy, reducing urine-related skin complications and improving cosmetic outcome.

🔍 Key Findings Summary

• Ex vivo cadaver study using 5 paired canine thoracic limbs
• Compared medial opening wedge osteotomy (MOWO) and external rotational osteotomy (ERO) of the humerus
• Measured pressure changes in the medial compartment using thin-film sensors
• ERO significantly reduced peak pressure and pressure distribution in the medial elbow compartment (p < 0.05)
• MOWO showed no significant pressure reduction relative to native state
• Combined MOWO + ERO did not significantly improve over ERO alone
• Findings support the biomechanical rationale for ERO as a surgical strategy to offload the medial compartment in cases like medial compartment disease (MCD)

🔍 Key Findings

• Plate–Pin TTT fixation resolved MPL in 64/65 stifles with low recurrence (1.5%) and good lameness outcomes postoperatively.
• Complication rate was 21.5% (14/65 stifles), mostly minor (57%); major issues included pin migration, fracture, or capsular failure.
• Pin-related issues accounted for 8 of 20 total complications, highlighting implant refinement is needed.
• No avulsions, TT fixation failures, or luxation recurrence occurred in cases where surgical technique was followed precisely.
• Surgical deviations increased complication risk 11.3× (p < 0.05), suggesting adherence to protocol is critical.
• Single-session bilateral MPL surgery had comparable complication rate (3/20) to unilateral surgery (11/45).
• Screw breakage occurred in 3 cases, suggesting at least 3 screws may be needed for secure TT fixation.
• Authors suggest temporary pin fixation and later removal may reduce complications, though prospective studies are needed.
