In İnal 2025 et al., on supracutaneous locking plates, which screw configuration was consistently used for adequate stability?
🔍 Key Findings
- Supracutaneous locking plates (SLPs) were successfully used to manage 33 diaphyseal fractures (radial–ulnar and tibial) in 30 cats and dogs.
- Median fracture healing time was 50.5 days (range: 27–88), with most patients regaining limb use within days postoperatively.
- CT-based metrics (callus area, HU, and 3D bone volume) increased significantly during healing (p < 0.05), validating CT as a quantitative tool for assessing healing.
- Complications were minimal: minor in 15/33 (e.g., screw tract discharge, edema), and major in 3/33 (e.g., implant failure, delayed union, nonunion).
- Minimally invasive osteosynthesis required longer surgery times than closed reduction (p < 0.05), but both techniques were viable.
- SLPs enabled successful bilateral fracture management without inter-plate interference due to their compact design.
- Screw orientation challenges were noted in cats, especially with cranial application to the radius due to narrow anatomy.
- Polyaxial locking screws were used safely and did not dislodge, allowing for angular insertion (≤10°) to avoid neurovascular structures.

In Takagi 2022 et al., on hepatic venous anatomy, which liver lobe consistently showed a single hepatic vein draining into the caudal vena cava or via the left hepatic vein?
🔍 Key Findings
- Hepatic venous drainage patterns vary widely across all lobes, especially the left lateral lobe.
- Right lateral lobe had a median of 2 vessels draining directly into the caudal vena cava (CVC); range: 1–4.
- Caudate process of caudate lobe had the most variability: 1–5 vessels draining into the CVC; 2 vessels was most common (54.5%).
- Left lateral lobe drained via 2–8 veins into the left hepatic vein (LHV), with 3 veins most common (31.2%).
- Left medial lobe typically had 1 vein draining into the LHV (61% of dogs).
- Papillary process drained into the LHV in 93.5% of cases; 6.5% drained directly to the CVC.
- Quadrate lobe always had 1 vessel draining either directly to the CVC or via the LHV.
- CTA revealed more variations than previously described in plastinated or cadaveric studies, highlighting its superior value in surgical planning.

In Hildebrandt 2023 et al., on Buccal Transposition Flap for Maxillary Lip Reconstruction in Dogs, what was the primary vascular supply to the buccal transposition flap identified on CT?
🔍 Key Findings
- Buccal transposition flap provided successful closure of large maxillary lip defects in all 5 dogs
- All flaps survived, with 3 dogs experiencing minor complications (e.g., fistulas, dehiscence) that resolved
- Flap vascularization originated from the angularis oris and superior labial arteries, as confirmed via CT angiography
- Excellent cosmetic and functional outcomes were achieved in all cases
- Ex vivo cadaver study validated flap perfusion, showing consistent contrast filling of key arteries
- Oronasal fistulas occurred in 2 dogs at the palatal incision site, likely due to contact with the mandibular canine tooth
- Mandibular canine coronectomy was performed in 2/5 dogs to prevent flap trauma
- Flap design and commissure positioning were customizable, aiding tension relief and improving outcomes

In Isono 2025 et al., on tibial malalignment in MPL, which of the following parameters was newly introduced and found to correlate with both TTA and CRA?
🔍 Key Findings
- Proximal Tibia Metatarsal Angle (PTMTA) was significantly increased in dogs with grade 3 and 4 MPL, making it a useful marker for severity.
- PTMTA strongly correlated with Tibial Torsion Angle (TTA) (r = 0.733) and Crural Rotation Angle (CRA) (r = 0.643), integrating multiple morphological deformities.
- Grade 4 MPL cases showed significant internal tibial torsion, increased mMPTA, and decreased MDTT/PTW—indicating both rotation and medial displacement.
- DTMTA was significantly more negative in grade 4, indicating a consistent pattern of internal foot rotation with disease severity.
- PTMTA can be visually assessed during palpation, offering preoperative utility without CT.
- Among toy poodles, PTMTA showed significant differences even between grades 3 and normal, suggesting breed-specific severity patterns.
- Corrective osteotomy may need to address tibial as well as femoral deformities in severe MPL cases with high PTMTA.
- Younger dogs with grade 4 MPL had more severe deformities, possibly due to early onset or developmental progression.

In Schmutterer 2024 et al., what was concluded regarding femorotibial kinematics when changing flexion angles?
🔍 Key Findings Summary
- Biomechanical study on 14 hindlimbs from Retrievers (cadaveric)
- Three stifle flexion angles tested: 125°, 135°, and 145°
- Contact Force Ratio (CFR) was significantly higher at 125° and 135° than at 145° (p < 0.001)
- Center of force shifted caudally with increasing flexion — especially in medial meniscus
- Lateral meniscus peak pressure was significantly higher at 125° than 145° (p = 0.049)
- Mean pressures on lateral meniscus decreased with extension, while medial meniscus pressure remained constant
- Relevance: Helps interpret meniscal load in early cruciate disease and in surgical modeling

In Banks 2024 et al., on CCWO planning accuracy, which **group based on preoperative TPA** was closest to the 5° TPA target postoperatively?
🔍 Key Findings
- Oxley's modified CCWO did not achieve the target TPA of 5° in most cases, even with planning.
- Mean planned TPA was 7.6°, higher than target, and consistent across dog sizes.
- Postoperative TPAs were significantly higher in small dogs (median 7°) than in large dogs (median 4.5°).
- Distalization >7.5 mm of the osteotomy from the patellar tendon led to increased under-correction of TPA.
- Only dogs with preoperative TPA >35° achieved post-planning TPAs close to the 5° target.
- Postoperative osteotomy positions were generally more distal than recommended (8.6 mm median).
- Virtual plate fit was appropriate for all dogs at 5 mm or 7.5 mm positions, suggesting no need for excessive distalization.
- Excessive correction leading to negative TPAs occurred in some cases, risking caudal cruciate ligament strain.

In Dalton 2023 et al., on acetabular fracture repair, what was the maximum fracture gap observed postoperatively in the cadaver study?
🔍 Key Findings
- Minimally invasive repair of acetabular fractures using precontoured plates on 3D-printed models is feasible and technically reproducible in dogs.
- All cadavers had fracture gaps <2 mm and step defects <1 mm, indicating accurate reduction.
- Sciatic nerve injury was minimal or absent in all cases, supporting potential neuroprotection from indirect approaches.
- Pelvic angulation was maintained <5°, confirming preservation of alignment post-reduction.
- Surgical time averaged ~46 minutes in cadavers for both approaches and repair.
- Clinical case showed good radiographic healing by 8 weeks and full union by 3 months, with early weight-bearing post-op.
- Use of locking screws improved reduction fidelity, particularly across a broad plate span.
- 3D printing accelerated surgical planning, though its necessity remains debated due to the availability and cost concerns.

In Moreira 2024 et al., on predictive equations for TPA correction, which technique demonstrated the **highest TLA shift** after cranial cortical alignment?
🔍 Key Findings
- A linear relationship was observed between wedge angle and tibial plateau angle (TPA) correction across all four CCWO techniques.
- All techniques produced predictable TPA corrections using linear regression-derived equations, allowing wedge angle extrapolation to achieve a target postoperative TPA of 5°.
- TLA shift (tibial long axis) increased with wedge angle and influenced final TPA; greatest in Frederick & Cross method.
- Tibial shortening (mTL%) varied by technique, being most severe (up to 40.9%) in traditional Slocum & Devine CCWO and least in newer techniques (7.5–12%).
- The Oxley mCCWO technique showed lower TLA shift compared to the Frederick & Cross and Christ techniques, though similar to Slocum & Devine; tibial shortening was more pronounced than other modified techniques at wedge angles ≤40°.
- Techniques varied in craniocaudal translation and wedge apex positioning, influencing planning accuracy and mechanical axis alignment.
- The corrective wedge angle equations reliably predicted TPA within 4–6° across varied tibial conformations.
- The study supports equation-based planning over static TPA–5° subtraction to reduce risk of under- or over-correction.
