In Hanlon 2022 et al., on short screw sacroiliac fixation, what complication was observed in some short screw cases?
🔍 Key Findings
- Two short screws (SLS or SPS) provided >2× peak load, yield load, and stiffness vs a single long screw (LLS) for SI joint stabilization.
- No mechanical advantage was seen between the two short screw types (lag vs positional).
- All short screws terminated lateral to the spinal canal, avoiding spinal impingement.
- Ventral sacral foraminal impingement occurred in 3 short-screw cases (1 SPS, 2 SLS), all involving the caudal screw.
- LLS group showed more abaxial displacement at osteotomy sites, suggesting inferior stabilization for concurrent pelvic fractures.
- Short screw constructs had longer total screw length (48 mm) than LLS (40 mm), contributing to increased stiffness.
- Positioning of caudal screw in a cranial/craniodorsal trajectory may help avoid nerve foraminal injury.
- No significant difference in displacement at peak load among groups; stiffness and load capacity were the primary benefits.

In Zann 2023 et al., on proximal humeral OC surgery, what difference was found in shoulder extension in unilaterally affected dogs?
🔍 Key Findings
- All dogs developed progressive osteoarthritis (OA) after surgical debridement of proximal humeral OC.
- Ipsilateral muscle atrophy and reduced shoulder range of motion were common, particularly in unilaterally affected dogs.
- Arthroscopically, lesions showed incomplete cartilage infilling even years after surgery, averaging only ~37% infilling.
- Synovitis was present in all joints, with moderate-to-severe hypertrophy and vascularity scores.
- CT identified OC lesions as deeper and wider than radiography, and all affected joints had more advanced OA than contralateral limbs (P = .001 radiograph, P = .005 CT).
- Kinetic gait analysis showed no significant differences in peak vertical force or impulse, but a subtle 4.4% asymmetric load reduction on the operated limb.
- Median LOAD score was 6, indicating mild owner-perceived disability despite measurable clinical and imaging abnormalities.
- Cartilage infilling was incomplete in all cases, with no lesion exceeding 60% restoration, raising questions about the healing potential of debridement alone.

In Isono 2025 et al., on tibial malalignment in MPL, which finding best characterized grade 4 medial patellar luxation?
🔍 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 Takagi 2022 et al., on hepatic venous anatomy, what major advantage does computed tomography angiography (CTA) offer compared to plastination or cadaveric methods?
🔍 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 Cheon 2025 et al., on guide accuracy in DFO, which of the following was a limitation of the universal guide?
🔍 Key Findings
- Both patient-specific and universal guides yielded correction errors <2°, with no statistically significant difference in accuracy.
- Universal guide corrected aLDFA up to 24° and AA up to 20°, addressing multiplanar deformities effectively.
- Patient-specific guides allowed for preoperative simulation, providing more stable pin placement and potentially aiding less-experienced surgeons.
- Universal guide eliminated the need for CT-based customization, reducing time and cost.
- Cadaver and bone model trials showed consistent accuracy, validating both methods in vitro and ex vivo.
- No significant differences in outcome when correcting uniplanar (aLDFA) vs biplanar (aLDFA + AA) deformities.
- Universal guide's fixed size presented limitations in small dogs, potentially requiring multiple size options.
- Universal guide showed potential for standard use, offering repeatable outcomes with minimal prep despite needing precise intraoperative placement.

- 20 screws placed using CBCT-based navigation with real-time tracking
- 85% (17/20) of screws were safely and accurately placed
- Median deviation of screw entry points from plan: 1.8 mm
- All 3 misplaced screws occurred in a single cadaver, attributed to inexperienced drill handling
- Custom 3D-printed lightweight tracking array was necessary due to small spinous processes in miniature dogs
- No iatrogenic canal perforations or vertebral damage in any specimen
- Concludes neuronavigation offers precise, safe placement of spinal implants in small dogs, with minimal anatomic disruption

In Grimes 2022 et al., on PDA rupture risks, what factor was significantly associated with increased residual flow after PDA ligation?
🔍 Key Findings
- Rupture occurred in 7.0% of dogs undergoing surgical PDA ligation (20/285).
- Overall mortality was low (0.4%), with only one death occurring post-rupture.
- Residual flow occurred in 9.4% of dogs; significantly more common in dogs with rupture.
- Residual flow odds were not increased when ligation was successfully performed despite rupture.
- No significant associations between rupture and age, weight, suture size, or dissection technique.
- Jackson-Henderson and intrapericardial techniques were helpful in managing rupture or fibrosis.
- Major complications (non-rupture) were rare (1.4%), including pulmonary artery ligation and cardiac arrest.
- Surgeon preparedness (e.g., hemostatic tools, alternate techniques) was key to successful outcomes.

In Marchionatti 2022 et al., on antiseptic efficacy comparison, which of the following best reflects the conclusion?
🔍 Key Findings
- Chlorhexidine-based asepsis protocols were comparable to povidone-iodine for reducing surgical site infection (SSI) rates in veterinary surgery.
- No significant difference in skin bacterial colonization was observed between the two antiseptics, at both immediate and delayed timepoints.
- Chlorhexidine-alcohol protocols showed a non-significant trend toward improved bacterial reduction in some studies, though inconsistent across all studies.
- Use of neutralizing agents was inconsistent, which may have led to overestimation of antiseptic efficacy in several studies.
- Formulations and concentrations varied widely (e.g., chlorhexidine 0.5–4%, povidone-iodine 0.7–1%), contributing to heterogeneity and limiting definitive conclusions.
- Only a minority of studies reported using CDC criteria for SSI diagnosis, affecting the reliability of infection outcomes.
- Risk of bias was high or unclear in multiple domains across all included studies, limiting overall confidence in conclusions.
- Meta-analysis confirmed no statistically significant superiority of either protocol for SSI prevention or skin bacterial reduction.
