In Zann 2023 et al., In Long-term outcomes after proximal humeral OC debridement in dogs, how did kinetic gait analysis compare affected and unaffected limbs?
🔍 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.

In Yu 2026 et al., on elbow OA surgery outcomes, evaluating harm via number needed to harm (NNH), which procedure had the best safety profile?
🔍 Key Findings
- Canine unicompartmental elbow (CUE) had the highest reported success (91–98%) and the second-best safety profile (NNH = 7.6).
- Sliding humeral osteotomy (SHO) showed moderate success (43–82%) but had the best safety profile (NNH = 9.5).
- Overall evidence quality was low, with no Level I studies and only five Level II (prospective) studies.
- Success measures were inconsistent, often based on subjective outcomes (e.g., owner satisfaction), limiting comparability.
- Adverse events were common, with high complication rates in arthrodesis and total elbow arthroplasty (TEA).
- One study using objective outcome (PVF) showed only 43% long-term success for SHO, suggesting possible overestimation of success in subjective studies.
- The review highlights the need for validated, standardized outcome tools in elbow OA surgery trials.
- Number needed to harm (NNH) emerged as a more consistent and informative safety metric than success percentages.

In Danielski 2025 et al., on PUO complication reduction, what was the **overall complication rate** reported with IM pin and rhBMP-2 use?
🔍 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.

In Quitzan 2022 et al., on staple line configuration, where did initial leakage most frequently occur in the FEESA constructs?
🔍 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.

In Buote 2023 et al., on 3D printed cannulas, what was the primary benefit observed in cadaver surgeries when using 3D printed cannulas (3DPCs)?
🔍 Key Findings
- Customized 3D printed cannulas (3DPCs) significantly reduced surgical time in feline cadaver models (125.6 vs. 95.2 min, p = 0.03).
- Use of 3DPCs resulted in a reduction in instrument collisions (6.8 vs. 2.6, p = 0.03).
- Cannula pullout complications decreased with 3DPCs (10 vs. 2.2 per procedure, p = 0.03).
- 3DPCs were designed at shorter lengths (3 cm), improving intra-abdominal working space in cats.
- No incisional or postoperative complications occurred in the two live feline cases.
- One 3DPC insufflation port broke intraoperatively; resolved by using a male luer lock connector in the next case.
- CO₂ leakage occurred from re-used silicone valves in 2 ports; emphasizing the need for durable valve design.
- Estimated cost per 3DPC was <$5.00, suggesting cost-effective customization for feline laparoscopy.

In Kalmukov 2022 et al., on cell salvage efficacy, which statement is TRUE regarding post-salvage PCV values?
🔍 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 Becker 2026 et al., on lumbar spine PLC biomechanics, what explanation was given for the preservation of rotational stability despite PLCs?
🔍 Key Findings
- Each PLC significantly increased passive range of motion (ROM) in the sagittal and dorsal planes (p < .05).
- No significant change was observed in rotational ROM after either PLC.
- First PLC increased sagittal ROM by 2.4° (23% increase); second PLC added 1.0° (8% increase).
- Dorsal ROM increased by 2.3° after first PLC and 1.5° after second PLC.
- Second PLC did not cause greater destabilization than the first — both contributed similarly to ROM increase.
- Failure testing showed that spinal segments with two PLCs failed at 13 Nm, while native spines withstood up to 25 Nm, suggesting reduced load-bearing capacity but not clinically significant under normal conditions.
- Rotational stability was preserved, possibly due to intact facet joints and lamina, which play a larger role in rotation.
- Study supports the clinical feasibility of two consecutive PLCs, but cautions against excessive bone removal due to potential for spinal instability.

In Hoenecke 2025 et al., on radiographic opacity in patella luxation, what percentage of dogs with long-term follow-up developed subsequent CCL rupture?
🔍 Key Findings
- 65% of stifles with patella luxation and intact CCLs had increased radiographic soft tissue opacity
- Weight and radiographic OA were significantly associated with increased opacity (p = .0029 and p = .0143)
- Each 1 kg increase in weight increased the odds of opacity by 10%
- Grade of patella luxation, age, and muscle atrophy were not significantly associated with increased opacity
- 19% of dogs with long-term follow-up developed a CCL rupture post-patella surgery, 50% of those had opacity at initial presentation
- Radiographic opacity alone should not be interpreted as CCL disease in dogs with patella luxation
- Radiographic findings likely represent effusion or synovial hyperplasia, not CCL pathology
- Arthrotomy was used to confirm CCL integrity at surgery, but arthroscopy could provide better sensitivity

In Eiger 2024 et al., on NIRFA-ICG in axial flaps, which flap had the highest visibility score (VFP 4) across all surgeons?
🔍 Key Findings
- Caudal superficial epigastric (CSE) flaps were most visible with NIRFA, scoring 4/4 VFP in 97% of evaluations.
- CSE flap margins were altered in 65% of observations after NIRFA, showing the strongest influence on surgical planning.
- Thoracodorsal (THO) and omocervical (OMO) flaps had lower visualization scores, with 60–81% of images scoring below 2.
- Surgeons were 17–25 times more likely to adjust margins for CSE flaps versus OMO or THO based on fluorescence imaging.
- Poor inter-rater agreement was found for OMO (ICC 0.49) and THO (ICC 0.35); CSE had near-perfect agreement, but ICC was low due to uniform high scoring.
- Visualization was affected by flap depth and panniculus, making deeper vessels (OMO, THO) harder to see.
- Surgeons often shortened flap length and reduced flap area when modifying based on NIRFA results.
- Real-time angiosome visualization via NIRFA-ICG may reduce necrosis risk and improve patient-specific APF design.
