🔍 Key Findings

• Combined intramedullary (IM) pin and rhBMP-2 use resulted in a low complication rate (7.4%) after proximal ulnar osteotomy (PUO).
• Major complications occurred in 5.3% of cases (4 infections, 1 pin breakage with ulnar tilt requiring revision).
• Minor complications occurred in 2.1% of cases (seroma, delayed union).
• No cases of non-union were observed; 98.9% of limbs achieved radiographic healing by 6 weeks.
• IM pin breakage was noted in 11.8% of limbs but did not affect healing outcomes.
• Chondrodystrophic breeds made up 64.8% of the cohort and tolerated the procedure well.
• Compared to prior studies, complication rates were substantially reduced with this technique (prior major: 13.9%; this study: 5.3%).
• The use of rhBMP-2 likely enhanced early bone healing and provided biologic support, particularly important in breeds at higher risk of complications.

🔍 Key Findings

• Double-loop cerclage resisted the highest peak load (805 N) and maintained tension longer than twist (488 N) and single-loop (397 N) configurations.
• Double-loop cerclage sustained 500,000 cycles at 60–80% of peak load in some cases without loosening, outperforming other types.
• Twist knots loosened rapidly, often within 10 cycles even at low loads (100–390 N).
• Single-loop knots performed better than twist, with partial resistance up to 100,000 cycles at 160 N, but showed wide variability.
• All loosening occurred before wire breakage, indicating clinical failure would happen from slack, not fracture.
• Double-loop cerclage had highest initial tension (323 N) compared to single-loop (124 N) and twist (69 N).
• Fatigue limit was not identified for twist, since they all loosened early at even 20% of peak load.
• Clinical recommendation: double-loop cerclage is best for resisting repeated subfailure loading, ideal for fissure prevention or fragment stabilization.

🔍 Key Findings

• Oxley's modified CCWO did not achieve the target TPA of 5° in most cases, even with planning.
• Mean planned TPA was 7.6°, higher than target, and consistent across dog sizes.
• Postoperative TPAs were significantly higher in small dogs (median 7°) than in large dogs (median 4.5°).
• Distalization >7.5 mm of the osteotomy from the patellar tendon led to increased under-correction of TPA.
• Only dogs with preoperative TPA >35° achieved post-planning TPAs close to the 5° target.
• Postoperative osteotomy positions were generally more distal than recommended (8.6 mm median).
• Virtual plate fit was appropriate for all dogs at 5 mm or 7.5 mm positions, suggesting no need for excessive distalization.
• Excessive correction leading to negative TPAs occurred in some cases, risking caudal cruciate ligament strain.

🔍 Key Findings

Design: Ex vivo cadaver study (n=8 dogs, 24 sites)
Comparison: Freehand vs. 3D-printed drill guide-assisted ventral slot (GAVS vs FHVS)
Findings:

• GAVS produced slots not significantly different from planned dimensions (p = .722–.875)
• FHVS produced significantly shorter slots than intended (p < .01)
• No difference in surgical time (p = .071)
• Shape ratio and slot divergence from midline were similar between groups (p > .4)
• Use of guide significantly reduced variability in slot position (63% → 29%), shape (65% → 24%), and divergence (54% → 50%)

Conclusion: 3D-printed guides improved accuracy and consistency of ventral slot creation by novice surgeons; supports future evaluation in live dogs and small breeds

🔍 Key Findings

• Surgical excision of insulinomas resulted in euglycemia or hyperglycemia in 90% of cats immediately post-op.
• 18/20 cats (90%) survived to hospital discharge, with a median survival time of 863 days.
• Younger age, metastasis at surgery, tumor invasion, and lower glucose levels were negative prognostic factors.
• Two cats had stage III disease with metastasis; one lived 413 days post-op, suggesting some benefit to surgery even in advanced disease.
• Postoperative hypoglycemia and seizure activity were associated with poorer outcomes; one cat euthanized due to seizures despite euglycemia.
• Median disease-free interval (DFI) was 1052 days; for cats with metastasis, DFI dropped to 93 days.
• Partial pancreatectomy was performed in 11 cats, nodulectomy in 10, and enucleation in 1; method of resection not linked to outcome.
• Postoperative complications occurred in 25% of cats; most were manageable with supportive care.

🔍 Key Findings

• Nasopharyngeal collapse was significantly more severe in brachycephalic dogs (median 65%) than in nonbrachycephalic controls (median 10%) (p = .0001).
• Postoperative fluoroscopy showed no significant improvement in nasopharyngeal collapse (p = .0505), despite reported clinical improvement.
• 70% of brachycephalic dogs had ≥50% collapse; 26% had 100% collapse preoperatively.
• All owners of surgical cases reported clinical improvement, including reduced respiratory noise and improved exercise tolerance.
• Surgical techniques used included combinations of alaplasty, staphylectomy, sacculectomy, and tonsillectomy.
• Improvement in nasopharyngeal dimensions was variable, with some dogs improving ≥45%, some worsening, and one dog showing a 100% increase post-op.
• Pharyngeal collapse may not be solely anatomical; neuromuscular dysfunction (e.g., reduced pharyngeal dilator muscle function) may contribute.
• Current surgical techniques may not address functional airway abnormalities, suggesting a need for multimodal or targeted interventions.

🔍 Key Findings

• Laparoscopic cholecystectomy (LC) was successfully performed in all 22 cats without conversion to open surgery.
• Complication rate was low: 3 cats had postoperative complications (1 seroma, 1 vomiting, 1 EHBDO and death).
• Median operating time was 41 minutes; median hospitalization was 3 days.
• No cases required conversion to open laparotomy, even in cats as small as 2.5 kg.
• Common devices used: Hemoclips or Hem-o-lok for cystic duct ligation; Ligasure, harmonic scalpel, or j-hook for dissection.
• Most common indications: cholelithiasis (9/22) and cholecystitis (10/22), with one biliary mucocele and one adenoma.
• Histopathology confirmed diagnosis in all cases; concurrent liver or intestinal biopsies were performed in some cats.
• Postoperative AUS and bloodwork were routine and important for detecting early signs of EHBDO.

🔍 Key Findings

• CPAP at 5 cmH₂O via helmet significantly improved PaO₂/FiO₂ ratio in the early postoperative period of brachycephalic dogs, supporting enhanced pulmonary oxygen exchange (p = .04).
• CPAP had no significant effect on SpO₂ (p = .9), PaCO₂ (p = .18), or rectal temperature (p = .5).
• Helmet tolerance decreased over time, with 13 dogs withdrawn for intolerance (9 CPAP, 4 control) and 6 dogs withdrawn for airway compromise (5 control, 1 CPAP).
• CPAP group maintained PaO₂/FiO₂ ratios near or above 400 mmHg, while control dogs showed consistently lower values.
• Authors suggest PaO₂/FiO₂ is a more reliable oxygenation measure than SpO₂ for evaluating postoperative lung function.
• The study found no cases of hyperthermia; temperatures normalized over time in both groups.
• Arterial catheterization failed in several dogs, limiting blood gas analysis to a subset of the population.
• Authors recommend further studies focused on BOAS patients and exploring longer-duration CPAP use to assess impact on critical outcomes like tracheostomy rates or hospitalization.

🔍 Key Findings

• Cystoscopic-guided laser ablation (CLA) was associated with significantly fewer minor complications (13%) than neoureterostomy (100%) (P < .01)
• CLA resulted in significantly fewer recurrences of incontinence compared to neoureterostomy (0/7 vs 5/12; P < .05)
• 80% of dogs achieved continence within 1 month postoperatively, with a median continence score of 10
• Long-term continence was achieved in 88% of dogs, with or without adjunctive treatment, over a median of 66 months
• Major complications occurred in only 8% of dogs, and all were successfully managed with surgical revision
• Persistent ureteral remnants were seen only in neoureterostomy dogs, potentially contributing to incontinence recurrence
• All dogs with incontinence recurrence responded to medical treatment, while only 1/5 with persistent incontinence after surgery did
• CLA is recommended over open surgery for iEU correction, due to lower complication and recurrence rates

🔍 Key Findings

• 3D-printed drill guides (3D-GDT) significantly reduced craniocaudal and dorsoventral drilling angle deviation compared to free-hand drilling technique (FHDT), with statistical significance (p < .0001 and p = .01 respectively).
• No sacral corridor breaches occurred with 3D-GDT, whereas FHDT resulted in 20% drill exit incidences (3/15 cases).
• 3D-GDT had lower deviation from optimal drill trajectory at end points in all axes: craniocaudal (1.84 ± 1.6 mm vs. 4.18 ± 2.4 mm), dorsoventral (1.11 ± 1.0 mm vs. 2.4 ± 1.5 mm), and 3D linear (2.47 ± 1.4 mm vs. 5.35 ± 2.2 mm), all statistically significant.
• Strong correlation (r = 0.77) between CT and 3D software measurements validated method reliability.
• 3D guide trajectories showed consistent proximity to the optimal trajectory, especially at drill endpoints, indicating reduced variability in execution.
• 3D-GDT was developed using open-source software and inexpensive materials, supporting future clinical application.
• Major errors in FHDT occurred primarily at the drill endpoint, underscoring the challenge of maintaining optimal angulation during free-hand drilling.
• The sacral corridor was recharacterized as pyramidal (not quadrilateral), with implications for safer implant placement.
