In Sherman 2023 et al., on minimally invasive ESF, how did intraoperative imaging affect surgery time?
🔍 Key Findings
- 55 cases (49 dogs, 6 cats) with nonarticular tibial fractures were treated using linear ESF with a minimally invasive approach
- All fractures achieved radiographic union; no unacceptable outcomes were reported
- 40% complication rate, mostly minor (82%), primarily pin-tract morbidity; major complications (7%) included osteomyelitis and refracture
- Open fractures had significantly more major complications than closed ones (P = .019)
- Use of intraoperative imaging (72% cases) reduced surgery time but did not improve alignment (P > .05)
- Median surgery time: 74 min with imaging vs. 100 min without (P = .046)
- TPA was lower than normal in both dogs and cats, but did not correlate with poor outcomes
- 62% had full clinical recovery, and 38% had acceptable outcomes at fixator removal

In Burkhardt 2024 et al., on coagulation testing in liver lobectomy, what did the authors recommend regarding preoperative PT and aPTT testing?
🔍 Key Findings
- 20.6% of dogs had a preoperative prolongation in PT or aPTT, but only 5.6% had both prolonged.
- Hemangiosarcoma was the only tumor type significantly associated with both PT and aPTT prolongation (37.5% of hemangiosarcoma cases, p < .001).
- Dogs with both PT and aPTT prolongations were 6.5× more likely to have emergency surgery (p < .001) and 2.5× more likely to have hemoabdomen (p = .0022).
- 60% of dogs with both PT and aPTT prolongation required blood transfusion (p < .001).
- Only 1.9% of all dogs had both PT and aPTT prolonged by >25%, suggesting limited clinical utility of routine PT/aPTT testing.
- Platelet count <50,000/μL was rare (1.5%) and not associated with PT/aPTT changes or transfusions.
- Routine PT/aPTT testing offers low diagnostic yield in elective liver lobectomy cases.
- Authors recommend case-by-case PT/aPTT screening, especially when hemangiosarcoma or bleeding tendencies are suspected.

In Kang 2024 et al., on sacroiliac fixation strength, which construct had significantly higher maximum failure load under rotational force testing?
🔍 Key Findings Summary
- 20 cats with pelvic fractures treated using locking plates with only cortical screws
- 28 fractures stabilized (ilium: 17, acetabulum: 6, ischium: 3, pubis: 2)
- Implants: Primarily 1.5/2.0 mm LCPs or String-of-Pearls plates
- Major complications in 2/20 cases (10%): sciatic entrapment, malunion requiring THA
- Minor complications in 2/20 cases (10%): plate impingement, transient lameness
- Clinical union in all cats by 8 weeks; all cats returned to full function
- Authors conclude cortical screws alone can provide adequate fixation in feline pelvic fractures if screw purchase and bone quality are sufficient

- Accuracy: 90%+ for all in Reading 2
- Observer Effect: Significant improvement between first and second reading for less experienced observers (p < 0.05); learning curve evident.
- Meniscal lesions found:
- 9/12 in suspected late meniscal injury cases
- 19/40 in newly diagnosed CCL cases
- Most common = bucket handle tears
- Conclusion: Multidetector CTA is a clinically useful, non-invasive tool for identifying medial meniscal lesions in dogs with CCL disease.

In Kalmukov 2022 et al., on cell salvage efficacy, what was the main advantage of swab washing during intraoperative blood salvage?
🔍 Key Findings
- Direct suction salvaged more red blood cell mass (rbcM) than swab washing: 88.43% vs 84.74% (p = .015)
- Swab washing still achieved high recovery (84.74%), making it a viable adjunct when suction is not possible
- No significant difference in post-salvage PCV between methods (~34% for Su and ~33.9% for Sw)
- Total salvaged blood volume was significantly higher using direct suction (143 mL vs 139.8 mL; p < .001)
- Leukocytes are removed during salvage, potentially lowering risk of cytokine-mediated transfusion reactions
- Expired pRBCs were used, but device still achieved high RBC recovery, supporting clinical utility
- Swab washing via manual agitation may cause more RBC destruction than direct suction
- Cell salvage may avoid complications of allogeneic transfusions, like storage lesions and immunologic reactions

In Karlin 2026 et al., on acetabular cup radiography, which measurement showed significant inaccuracy when calculated using the CPAD?
🔍 Key Findings
- CPAD accurately measured angle of lateral opening (ALO) on sagittal radiographs with near-perfect agreement (Lin’s Rc = 0.994) compared with known angles.
- No significant difference between measured and true ALO values was detected (p = 0.655), supporting accuracy of the device for this parameter.
- Mean ALO measurement error was only 0.14° ± 1.18°, indicating high precision of the CPAD method.
- Open-face version measurements were significantly inaccurate compared with known values (p < 0.0001).
- Mean error in version measurement was 9.5° ± 6.31°, showing only moderate agreement (Rc = 0.424).
- Measurement error in version likely resulted from radiographic superimposition of the V-axis bar with the cup edge, making bar endpoints difficult to identify.
- CPAD accuracy for ALO (~1.18°) is nearly five times better than previous radiographic techniques, which typically achieve ~5° accuracy.
- Intraoperative fluoroscopic use of CPAD may allow real-time adjustment of cup orientation, potentially reducing luxation risk after canine THA.

In Welker 2024 et al., on thoracic duct anastomosis with MAC device, what complication was noted in two dogs postoperatively?
🔍 Key Findings
- Anastomosis of the thoracic duct (TD) to the intercostal vein (ICV) using a microvascular anastomotic coupler (MAC) was feasible in all 6 healthy dogs
- Immediate postoperative patency was confirmed in all dogs, but only 4/6 had patent anastomoses at 30 days, with 2 failing due to ICV kinking
- Kinking of the ICV near the azygos vein insertion was the primary failure mechanism, likely from MAC malalignment
- No intraoperative or major postoperative complications occurred, though 2 dogs developed mild seromas
- Use of the MAC device simplified microsurgical anastomosis versus hand suturing, especially in the deep thoracic cavity
- Contrast lymphangiography showed faster clearance from the cisterna chyli postoperatively, suggesting effective flow redirection
- Persistent branches of the thoracic duct may impact outcomes, and should be ligated during surgery
- This technique may be a potential novel treatment for idiopathic chylothorax, improving outcomes by reducing collateral flow stimuli

In Rocheleau 2025 et al., on infected total hip replacements, which pathogen was among the common isolates recovered?
🔍 Key Findings
Study Design: Case series of 8 dogs with confirmed or suspected PJI after total hip replacement (THR)
Dogs were categorized into:
- Curative intent (CI) group (n=5): short-duration infections, implant retention attempted
- Non-curative intent (NCI) group (n=3): chronic infections, implants scheduled for removal or revision
Success Rate: 7 of 8 dogs had infection resolution, including 4 of 5 in the CI group
Sampling sensitivity:
- Arthroscopic culture success was 80% in the CI group but only 33% in the NCI group
- All explanted implants from NCI group yielded positive cultures
Common isolates: Staphylococcus pseudointermedius (including MRSP), S. epidermidis, Stenotrophomonas maltophilia, and E. coli
Ancillary treatments included:
- Partial synovectomy, high-volume lavage (5–10 L), biofilm-depleting lavage, and/or amikacin-impregnated calcium sulfate beads
Mean follow-up: >1 year (mean 812 days); no signs of recurrence in successfully treated cases
Conclusions: Arthroscopic management of THR infections is feasible and effective in appropriately selected dogs. Success aligns with human literature when infection type is favorable (Type 1, 3, 4). Sensitivity of arthroscopic culture is higher in early/acute infections.
