In Jeon 2025 et al., on distal femoral shortening, what was the **outcome regarding neurovascular complications** post-DFSO?
🔍 Key Findings
- Distal femoral shortening osteotomy (DFSO) enabled prosthesis reduction in all 4 dogs with irreducible luxoid hips undergoing total hip replacement.
- Median femoral shortening ratio was 13.8% (range: 10.7–15.3%) based on intraoperative tension needed for prosthesis reduction.
- Bone union was achieved in all cases post-DFSO, indicating good healing potential.
- Two major complications occurred: one prosthetic luxation and one aseptic stem loosening requiring explantation.
- One intraoperative fracture of the greater trochanter occurred during trial reduction before DFSO.
- DFSO did not result in neurovascular injury, even in cases with significant femoral head displacement (>4 cm).
- Radiographic planning with FHD index and intraoperative assessment were crucial for determining DFSO necessity.
- DFSO avoids complications linked to subtrochanteric osteotomy by preserving proximal femoral anatomy and allowing secure distal fixation.

In Espinel Rupérez 2023 et al., on hip toggle stabilization, which intraoperative complication occurred most frequently?
🔍 Key Findings
- Arthroscopic-assisted hip toggle stabilization (AA-HTS) was successfully completed in all 14 feline cadaver joints.
- Femoral and acetabular tunnel creation was feasible in all cases, though femoral tunnel placement had a higher rate of deviations.
- Intraoperative complications occurred in 5/14 joints, mostly related to femoral tunnel creation and toggle lodging.
- Minor articular cartilage injury (<10% total cartilage area) occurred in 10/14 joints, but no injury to neurovascular or intrapelvic structures.
- Thirteen surgical technique deviations (8 major, 5 minor) were identified in 7 joints, all involving the femoral tunnel.
- Toggle passage through the femoral tunnel was the most challenging step, being mildly difficult in 6 joints.
- Postoperative CT and gross dissection confirmed all toggles and buttons were in correct position, without damage to major surrounding structures.
- No deviations, complications, or cartilage injuries occurred in the last 4 joints, suggesting a learning curve effect.

In Story 2024 et al., on surgical correction of excessive tibial plateau angle (eTPA), which technique caused the greatest cranial mechanical axis shift?
🔍 Key Findings
- All four techniques achieved TPA <14°, meeting the threshold for acceptable surgical correction in eTPA cases.
- Group A (CBLO + CCWO) and Group D (PTNWO) showed highest accuracy in achieving target TPA values.
- Group B (TPLO + CCWO) resulted in significant tibial shortening compared to other techniques.
- Group A caused the greatest cranial mechanical axis shift, while Group B caused the least.
- Group C (mCCWO) resulted in consistent under-correction of TPA, despite aiming for 0°.
- Modified or neutral wedge osteotomies (Groups C and D) had minimal effect on tibial length, making them suitable when preservation is important.
- All techniques involved mechanical axis shifts, highlighting the importance of preoperative planning to minimize morphologic disruption.
- Supplemental fixation was standard for all procedures to reduce risks such as tibial tuberosity fracture and plateau leveling loss.

In Otero Balda 2025 et al., on Short-term outcomes after feline cPSS surgery, what was the 30-day survival rate in cats that developed postattenuation neurologic signs (PANS) after surgical attenuation of a single congenital portosystemic shunt?
🔍 Key Findings
- 78% of cats that developed postattenuation neurologic signs (PANS) after congenital portosystemic shunt (cPSS) surgery survived to 30 days.
- Postattenuation seizures (PAS) were associated with significantly decreased 30-day survival (50% vs. 78%; OR: 0.015, p = .005).
- Treatment of PANS with propofol was a negative prognostic factor (OR: 0.112, p = .0008).
- Generalized PAS accounted for most seizure cases and were more frequently fatal than focal or unknown-type seizures.
- Pretreatment with levetiracetam (LEV1 protocol) showed a trend toward improved survival (100% vs. 60.6% in untreated cats), though not statistically significant (p = .06).
- Shunt morphology, method of attenuation, and study period (early vs. late) were not significantly associated with 30-day survival.
- Electrolyte, glucose, and ammonia abnormalities were not strongly linked to survival outcomes in this study.
- Majority of PAS-related deaths were due to uncontrolled generalized seizures or euthanasia because of severity.

In Chen 2024 et al., on pressure-measurement tools, why is high precision potentially more critical than accuracy when monitoring portal pressures during PSS ligation?
🔍 Key Findings
- WMg (water manometer with gauge) was the most accurate and precise pressure measurement device.
- APT (arterial pressure transducer) was less accurate than WMg but still precise; it differed significantly from the gold standard (WMr).
- CCT (Compass CT) was the least accurate and precise and differed significantly from the set pressure.
- Mean differences from set pressure were smallest for WMg (−0.020 cm H2O), moderate for APT (−0.390 cm H2O), and largest for CCT (−1.267 cm H2O).
- All devices showed excellent interobserver (ICC = 1.000) and intraobserver agreement (ICC range 0.985–0.998).
- Even though the CCT performed least well, all devices had mean errors ≤1.3 cm H2O, indicating potential clinical utility.
- WMg or WMr should be preferred in surgical settings due to superior accuracy and precision.
- Measurement precision is more critical than accuracy during PSS surgery, as a 1 mm Hg (~1.3 cm H2O) increase in portal pressure raises odds of poor outcomes by 9%.

In Sunlight 2022 et al., on Protein C monitoring, which variable was **not** significantly associated with ultimate clinical status?
🔍 Key Findings
- Postoperative Protein C (PC) activity increased in 78.7% of dogs, and was significantly higher in dogs with excellent clinical outcomes.
- Complete acute shunt occlusion resulted in higher postoperative PC activity (96.3%) and better ultimate clinical outcomes than incomplete occlusion.
- Preoperative PC was not predictive of clinical status, but postoperative PC was associated with improved outcomes.
- Standard biochemical markers (HCT, MCV, ALB, BUN) also improved postoperatively, especially in dogs with excellent clinical outcomes.
- Dogs requiring a second procedure had significantly lower postoperative PC (43.5%) than those not requiring further intervention (78.5%).
- Repeat procedures improved PC and BUN values, with PC increasing significantly after second intervention (to 69.8%).
- PC normalization (within reference interval) occurred in 87.5% of dogs with excellent clinical status, compared to only 12.5% in those with poor status.
- Clinical outcome classification (excellent/fair/poor) correlated with biochemical normalization and lack of need for diet/medications.

In Adams 2024 et al., on canine tibial plateau fractures, what was the long-term functional outcome for the two cases that completed LOAD questionnaires?
🔍 Key Findings
- Tibial plateau fractures (TPF) are rare in dogs, but can be surgically stabilized with good outcomes even in complex trauma cases.
- Lateral TPFs (Unger type 41-B1) were approached via caudolateral arthrotomy, with elevation of the lateral meniscus for visualization and use of lag screws and K-wires for fixation.
- Medial TPF (Unger type 41-B2) was addressed via medial parapatellar approach using K-wires and a figure-of-eight tension band.
- One minor complication occurred: implant yield at 2 weeks in a case with a concurrent fibular fracture, resulting in a 0.8 mm step defect.
- No major complications were recorded, and all dogs achieved clinical union with full function by 8–10 weeks.
- Long-term owner-reported outcomes (LOAD scores) were excellent (5/52), indicating minimal osteoarthritis or chronic pain.
- Concurrent fibular fractures may increase risk of implant failure and should influence implant selection (e.g., considering buttress plating).
- Arthroscopic-assisted techniques may be applicable in select cases, but open reduction was preferred due to fragment displacement or concurrent injuries.

In Smith 2024 et al., on ergonomics and preferences in veterinary laparoscopy, what type of instrument handles were most associated with increased difficulty in laparoscopic procedures?
🔍 Key Findings
- Surgeons with smaller glove sizes experienced more difficulty using laparoscopic instruments, especially endoscopic staplers, cup biopsy forceps, and vessel sealing devices.
- Endoscopic stapler was rated the most difficult instrument, with a median difficulty score of 4/10 and 25% usage difficulty.
- Female surgeons reported significantly more difficulty with several instruments due to smaller glove size.
- Reusable instruments were preferred over disposable ones for all tasks.
- Pistol grips were preferred for grasping/retracting and fine dissection, while axial grips were preferred for suturing/knot tying.
- Articulating handles were consistently associated with increased reported difficulty, especially with scissors and cup biopsy forceps.
- Left-handed surgeons had more difficulty operating endoscopic staplers, suggesting limited design inclusivity.
- Surgeons in academic settings reported more difficulty with laparoscopic maneuvers than those in private practice.

In Saylak 2026 et al., on feline ilium fixation, what technical feature of the M-CRIF construct facilitated stable fixation in the small feline ilium?
🔍 Key Findings
- All 36 feline corpus ilium fractures achieved union after fixation with either M-CRIF (n = 18) or conventional locking plates (n = 18).
- M-CRIF produced faster mid-term radiographic healing, with higher day-45 healing scores than locking plates (2.72 ± 0.46 vs 1.89 ± 0.83; p = .002); later healing scores were comparable.
- M-CRIF better preserved pelvic canal dimensions, with significantly less sacral index narrowing than plate fixation (p = .005).
- Screw loosening occurred in 22.2% (4/18) of plate cases but in none of the M-CRIF cases; one plate case required revision with an additional dorsal plate.
- The modified implant increased screw-placement flexibility, permitting four locking screws cranial and two caudal to the fracture while allowing clamps to be positioned at the required location and angle.
- M-CRIF required longer operative application, primarily because the rod had to be contoured intraoperatively, although application time decreased with surgeon experience.
- Neurological deficits decreased from 22.2% preoperatively to 5.5% postoperatively, suggesting generally favorable neurological recovery in the selected population.
- M-CRIF was considered a reliable alternative to conventional plating, offering greater fixation stability, fewer implant-related complications, and improved preservation of pelvic canal width.
