🔍 Key Findings

• Delayed union occurred in 13.9% of fractures; non-union in 4.6%; mal-union in 0.7%
• Major implant failure increased odds of delayed or non-union by 12.9×
• Surgical site infection increased risk 3.2×; bone grafting (any type) was also associated (OR 3.3)
• Comminuted fractures had 4.2× greater odds of delayed or non-union
• Older age increased risk, with odds increasing by 21% per year
• Radius and ulna fractures in toy breeds were not high risk, contrary to historical belief
• Most non-unions required revision surgery with rhBMP-2 or autograft to achieve union
• Ilium fractures showed 0% delayed/non-union — possibly due to robust muscle envelope

🔍 Key Findings

• 2.4 mm LCP with a 1.6 mm IM pin had the highest axial stiffness and yield strength among the tested constructs.
• Axial stiffness was significantly higher in the 2.4 mm LCP + 1.6 mm IM pin group compared to 2.7 mm LCP alone (p = .013).
• No significant difference in torsional stiffness was found among groups.
• 2.4 mm LCP + 1.0 mm pin had the lowest stiffness and failure load, underperforming both other constructs.
• All constructs failed via valgus bending, consistent with clinical observations in feline tibial fractures.
• A 1.6 mm pin (~50% canal fill) resulted in superior construct performance vs. 1.0 mm (~30% fill).
• Group 2 (2.4 LCP + 1.6 mm pin) outperformed the 2.7 mm LCP alone in stiffness, despite using a smaller plate.
• Plate–rod constructs may better preserve periosteal blood supply and support minimally invasive stabilization strategies.

🔍 Key Findings

• Liposomal bupivacaine (LB) infiltration did not reduce the need for rescue analgesia compared with placebo in dogs undergoing TPLO.
• CMPS-SF pain scores were not significantly different between LB and placebo groups at any postoperative time point.
• % body weight distribution (%BWdist) to the operated limb did not differ significantly between treatment groups across all time points.
• No correlation was found between CMPS-SF scores and %BWdist, suggesting these metrics assess different aspects of postoperative pain.
• Postoperative carprofen administration was standardized, and LB did not provide additional detectable analgesic benefit.
• Three-layer infiltration technique (joint capsule, fascia, subcutis) was used consistently across all cases.
• Adverse events were minor and comparable between LB and placebo groups.
• Post hoc analysis suggested a much larger sample size (58–436 dogs) would be needed to detect significant differences in %BWdist.

🔍 Key Findings

• 20 dogs (26 shoulders) evaluated at mean 3.5 years post-surgery after arthroscopic or open debridement.
• Ipsilateral muscle atrophy and decreased range of motion (↓ extension, ↓ flexion) in affected limbs compared to contralateral healthy shoulders.
• All treated shoulders developed osteoarthritis, confirmed radiographically, by CT, and arthroscopically.
• Moderate to severe synovitis was present in all shoulders; lesions showed patchy, incomplete cartilage infilling even up to 8.9 years post-op.
• Kinetic gait analysis showed no significant differences in PVF/VI between affected and unaffected limbs, despite mild lameness clinically.
• Owners reported good to very good mobility (median LOAD = 6), often underestimating clinical lameness.
• CT detected larger lesion dimensions than radiographs (wider, deeper defects).
• Despite progression of OA, surgical debridement was associated with satisfactory long-term function, though not prevention of degenerative changes.

🔍 Key Findings

Overall accuracy of radiography to detect IAIP: 77.9%

Sensitivity: 97.2%
Specificity: 67.6%

False positive rate: 32.4% of non-penetrating implants were misclassified as penetrating

Implants directed toward the lateral tibial condyle had higher misclassification (23.8%) than medial (8.3%)

Most accurate detection: Implants placed 2 mm into the joint (97.2% correct classification)

Least agreement: For implants placed at 0 mm (subchondral level), especially lateral (AC1 = 0.48)

No palpable abnormalities (e.g., crepitus) observed during ROM for any group

No significant difference in detection by specialty field or reviewer qualification

Suggests radiographic misclassification risk and supports considering CT/fluoroscopy in equivocal cases

🔍 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

• 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

• Ventricular fibrillation (VF) occurred in 3% of pericardiectomy cases across reporting institutions.
• 14 of 16 dogs (88%) that developed intraoperative VF died, indicating high mortality.
• Electrosurgical devices were used in 15/16 dogs; VF onset coincided with their use in 8 dogs, suggesting a potential but unproven association.
• Preoperative arrhythmias were seen in 7 dogs (e.g., VPCs, VT, bradycardia), possibly serving as early warning signs.
• Thoracoscopic approach was used in 75% of cases; however, conversion to open surgery was required in 9/13 thoracoscopic procedures after VF onset.
• Defibrillation was attempted in 13 dogs, but only 3 converted to sinus rhythm, and only 2 survived postoperatively.
• VF may result from stray current or cardiac manipulation; bipolar energy devices were implicated despite lower theoretical risk.
• Preventative strategies include judicious electrosurgery use, close ECG monitoring, rapid CPR preparedness, and preop cardiac risk assessment.

🔍 Key Findings

• No significant difference in initial leak pressure (ILP) among TA 30 V3 2.5 mm, TA 60 3.5 mm, and TA 60 4.8 mm stapler sizes (P = .78).
• All stapler types exceeded the physiological intraluminal pressure threshold (~25 mmHg), suggesting acceptable leak resistance.
• Mean ILPs: TA 30 V3 (181.5 mmHg), TA 60 3.5 mm (112 mmHg), TA 60 4.8 mm (77.2 mmHg).
• Leakage occurred at the staple line in 23 of 24 specimens; only one had ileal wall rupture.
• No correlation found between ILP and cadaver weight, cecal wall thickness, or cecal length.
• Cecal wall thickness averaged 4.9 mm, yet staple heights ranged only from 1.0–2.0 mm.
• One specimen in each TA 60 group leaked near or below physiologic pressures, suggesting rare outliers.
• Study supports clinical viability of all tested stapler sizes for canine typhlectomy, but highlights need for in vivo data on healing and complications.

🔍 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.
