🔍 Key Findings

• Roux-en-Y procedures were successfully completed in all 11 cases (6 dogs, 5 cats), despite case complexity and disease severity.
• Median survival post-discharge was longer in cats (365 days) vs. dogs (82 days), with better outcomes in non-neoplastic vs. neoplastic disease (192 vs. 5 days).
• Complication rate was high, with septic peritonitis, dehiscence, and cardiac arrest as leading causes of postoperative death; mortality rate = 36%.
• Dehiscence rate was 8.6% (2 of 23 anastomoses), considered lower than typical rates for GI anastomoses in high-risk patients.
• Feeding tubes (gastrostomy/jejunostomy) were used in all cases, enabling early nutritional support and stomach decompression.
• Postoperative nausea and vomiting were common but mostly self-limiting; managed with metoclopramide, cisapride, and antiemetics.
• Choledochojejunostomy was preferred when common bile duct was dilated, offering a favorable size match and potentially reducing bile leakage.
• Roux-en-Y reduced typical Billroth II complications (e.g., bile reflux, afferent loop syndrome, dumping syndrome), with none observed in discharged patients.

🔍 Key Findings Summary

• IMN provides relative stability, resists bending/torsion due to central axis alignment
• Larger diameter nails = exponentially greater stiffness (∝ D⁴)
• Trade-off: Larger interlocking holes weaken fatigue strength of the nail
• Reaming increases contact/stability but has pros/cons:
  • Improves outcomes in closed fractures
  • May reduce endosteal blood flow in thin-walled bones (e.g., cats)
• Design advances:
  • Angle-stable IMN reduce rotational slack
  • Expandable nails simplify insertion but may compromise removal or compressive load resistance
  • Precontoured nails match bone curvature but lack consistent clinical superiority
• Material debates continue (e.g., titanium vs. stainless steel vs. magnesium)

🔍 Key Findings

• Exercise-based rehabilitation showed benefits in 6 of 7 studies, including increased peak vertical force (PVF) and reduced lameness, though most had high risk of bias (RoB).
• Cold compression therapy (CCT) had 2 high-quality (Level II, low RoB) studies showing improvements in pain scores, range of motion, and swelling, supporting its clinical use.
• Extracorporeal shockwave therapy (ESWT) was supported by 2 Level II studies; only one had low RoB, showing short-term benefits in patellar ligament thickness and PVF, but no long-term benefit on bone healing.
• Photobiomodulation (PBM) had mixed results across 3 Level II studies (all low RoB); only 1 showed positive impact on PVF, limiting its recommendation.
• Low-intensity pulsed ultrasound (LIPUS) showed no significant impact on gait analysis or bone healing in a Level II, low RoB study.
• Electrical muscle stimulation (EMS) improved lameness and thigh circumference in one Level III study, but had high-moderate RoB and involved experimentally-induced CCL rupture, limiting clinical relevance.
• No modality beyond exercise and CCT had consistent or strong evidence for efficacy in post-TPLO or extracapsular repair rehabilitation.
• The absence of standardized protocols, small sample sizes, and inconsistent outcome measures limited the generalizability of findings.

🔍 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.

🔍 Key Findings

Population: 9 dogs underwent revision of osteointegrated acetabular cups after total hip arthroplasty (THA)

Revision Indications:

• 7 luxations (5 ventral, 2 craniodorsal)
• 1 femoral stem fracture
• 1 aseptic stem loosening

Implants:

• 8 BFX cups, 1 Helica; all revised to BFX
• 7/9 required a larger cup than original

Cup removal: Required sectioning with a high-speed burr and modular osteotome; removal fragments extracted

Complications:

• 1 recurrent luxation
• 1 low-grade infection with possible metallic debris-associated osteolysis
• 2 femoral fissures managed intraoperatively

Outcomes:

• Good to excellent function in 6/6 dogs available at median 621 days
• Minimal complications with success in re-osteointegration of new cup

Clinical takeaway: Revision of stable, ingrown cups is feasible and offers an alternative to pelvic osteotomies; typically requires upsizing

🔍 Key Findings

• All FEESA configurations leaked at lower pressures than intact segments, confirming reduced integrity vs. native tissue.
• FEESA with 3-row transverse staples (3V/3T or 2V/3T) had significantly higher leak pressures than 2-row configurations.
• 3V/3T configuration had the highest ILP (69.88 ± 21.23 mmHg) among all groups, significantly greater than 2V/2T and 3V/2T (P < .001).
• Leakage consistently occurred at the transverse staple line (not vertical), regardless of configuration.
• No significant difference in maximum intraluminal pressure (MIP) between FEESA groups.
• All FEESA constructs withstood intraluminal pressures >25 mmHg, exceeding normal physiological jejunal pressure in dogs.
• No leaks occurred from the vertical staple line, highlighting it as a more robust closure site.
• Third staple row in transverse line may be a viable alternative to suture oversew, pending further clinical evaluation.

🔍 Key Findings Summary

• 20 shoulders from 11 medium-to-large breed dogs evaluated
• Lateral portals used: middle arthroscopic, caudal instrument, cranial egress
• Musculotendinous lesions unavoidable, but small (18G needle); seen in deltoideus (90%), infraspinatus, teres minor, etc.
• Neurovascular safety:
  • Caudal portal was closest to axillary artery/nerve branches (as close as 7 mm)
  • Only 2/20 shoulders (10%) had omobrachial vein penetrated
• Cartilage injuries (IACI) occurred in 65%, primarily minor linear defects; use of guarded cannulas and distractors suggested for minimization
• Supports overall safety of lateral shoulder arthroscopy with portal placement awareness

🔍 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.

🔍 Key Findings

• Study Design: Prospective, randomized clinical trial of 45 dogs undergoing liver biopsy or lobectomy.
• Groups:
  • Adhesive gelatin sponge (AG) group (n=22)
  • Plain collagen sponge (PC) group (n=23)
• Main Results:
  • At 5 minutes post-application, 10/20 PC dogs were still bleeding vs. 2/20 AG dogs (p = 0.0138).
  • AG had significantly better adhesion scores (median 2 vs. 1, p < 0.001).
  • Sponge dislodgement: 5/23 in PC group, 0/22 in AG group (p = 0.042).
  • Time to 50% hemostasis: AG = 2 min, PC = 4 min 49 sec.
• Complications: No adverse events related to either sponge.
• Conclusion: Adhesive gelatin sponges offered superior intraoperative adhesion and hemostatic control during canine liver surgery compared to collagen sponges.

🔍 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.
