In Devriendt 2022 et al., on EHPSS blood testing, which single test had the highest **specificity** for confirming shunt closure after surgery?
🔍 Key Findings
- Fasting ammonia (FA) was the most specific test (100%) for confirming EHPSS closure postoperatively.
- Serum hyaluronic acid (SHA) and MEGX at 15 minutes post-lidocaine were the most sensitive tests (96.9% and 96.2%, respectively).
- SHA combined with MEGX T15, or with FA or postprandial serum bile acids (SBA), provided 100% sensitivity with good specificity (72.4–82.8%).
- SHA levels remained elevated in all dogs with persistent shunting, even when other tests were normal.
- Paired SBA had moderate sensitivity (90%) and variable specificity (89%).
- The L/MEGX test at 30 min was less useful than at 15 min for assessing closure.
- Traditional SBA testing showed reduced utility postoperatively; normal values did not rule out persistent shunting.
- Blood tests improved when combined, but imaging remains essential to definitively confirm EHPSS closure.

In Israel 2023 et al., on povidone-iodine lavage, which of the following was *not* a complication noted in PrePIL cases?
🔍 Key Findings
- No infections (0/102) occurred in cases where preclosure povidone-iodine lavage (PrePIL) was used, compared to 21/2111 (0.99%) with saline lavage.
- Break-even cost for PrePIL was calculated at $49.74, while the actual cost was only $2.07, confirming strong cost-effectiveness.
- No adverse reactions or healing complications were reported in the 102 PrePIL cases.
- The PrePIL protocol used 0.35% povidone-iodine for 3 minutes before closure, followed by sterile saline lavage.
- Majority of THRs (97%) used cementless fixation (BFX) in PrePIL group; only 3 cases used CFX components.
- Surgeries followed consistent perioperative antibiotic protocols, making PrePIL the only major protocol variable.
- Antibiotics were not added to lavage, aligning with WHO and CDC guidelines for antimicrobial stewardship.
- The infection reduction with PrePIL supports routine use in total hip replacement to reduce periprosthetic joint infections.

In Rocheleau 2023 et al., on shoulder stabilization, which stabilization technique showed a statistically significant reduction in abduction angle postoperatively?
🔍 Key Findings
- Arthroscopically assisted stabilization with an IAD was feasible in cadaveric canine shoulders using both bone anchor and suture-toggle techniques.
- Suture-toggle repair was successfully performed in all specimens, while bone anchors could not be deployed in 3/10 shoulders, indicating lower feasibility.
- Median surgical time was shorter for the suture-toggle group (25.5 min) compared to the anchor group (37.3 min).
- Postoperative abduction angles returned to baseline in the anchor group, while the suture-toggle group had slightly reduced angles, suggesting possible overtightening.
- Violation of the articular surface occurred in 2 anchor specimens and 1 suture-toggle specimen, but none were considered likely to be clinically significant.
- Overall targeting accuracy using the IAD was 88%, supporting its utility in guiding tunnel/anchor placement.
- CT measurements showed acceptable bone stock and insertion angles, but anchor insertion angles were lower than optimal for mechanical pullout strength.
- Suture-toggle technique was considered simpler and more consistent, with fewer complications and faster execution than anchor placement.

In McCarthy 2022 et al., on 3D drill guide accuracy, what was the advantage of 3D-GDT in terms of drill end point deviation?
🔍 Key Findings
- 3D-printed drill guides (3D-GDT) significantly reduced craniocaudal and dorsoventral drilling angle deviation compared to free-hand drilling technique (FHDT), with statistical significance (p < .0001 and p = .01 respectively).
- No sacral corridor breaches occurred with 3D-GDT, whereas FHDT resulted in 20% drill exit incidences (3/15 cases).
- 3D-GDT had lower deviation from optimal drill trajectory at end points in all axes: craniocaudal (1.84 ± 1.6 mm vs. 4.18 ± 2.4 mm), dorsoventral (1.11 ± 1.0 mm vs. 2.4 ± 1.5 mm), and 3D linear (2.47 ± 1.4 mm vs. 5.35 ± 2.2 mm), all statistically significant.
- Strong correlation (r = 0.77) between CT and 3D software measurements validated method reliability.
- 3D guide trajectories showed consistent proximity to the optimal trajectory, especially at drill endpoints, indicating reduced variability in execution.
- 3D-GDT was developed using open-source software and inexpensive materials, supporting future clinical application.
- Major errors in FHDT occurred primarily at the drill endpoint, underscoring the challenge of maintaining optimal angulation during free-hand drilling.
- The sacral corridor was recharacterized as pyramidal (not quadrilateral), with implications for safer implant placement.

In Sabol 2024 et al., what was the general distribution pattern of corridor widths across T1–T13?
🔍 Key Findings Summary
- Evaluated ideal dorsolateral implant trajectories in T1–T13 using CT in 30 dogs across five weight classes.
- Corridor widths were narrowest in the mid-thoracic vertebrae (as little as 1.8 mm) and increased cranially and caudally.
- Allowable deviation angles (ADA) were often very small (as little as 3°), indicating high risk for canal or thoracic structure breach.
- Distances to critical structures (lungs, aorta, subclavian artery, azygos vein) were often <1 mm, even in large dogs.
- Data suggest extreme caution and precision are needed for thoracic vertebral implant placement and support use of navigation or 3D-printed guides.

In Horwood 2024 et al., on complications in luxoid hip dysplasia, which cup orientation angle was associated with increased risk of postoperative luxation?
🔍 Key Findings
- Luxoid hip dysplasia (LH) was present in 8% of THA cases and significantly increased risk of major complications (p < .001).
- Intraoperative fissures/fractures were 3x more likely in LH dogs vs non-LH (39% vs 16%, p = .001).
- Dorsal luxation was more frequent in LH dogs (28% vs 4%, p = .019).
- Acetabular cup placement with ALO >35° was associated with luxation in LH dogs.
- Morphologic abnormalities (e.g., femoral valgus, lateralization/medialization of cortices) were common in LH and may complicate implantation.
- Despite higher risk, 94% of LH dogs achieved satisfactory outcomes after appropriate revisions.
- Younger age and lighter weight characterized LH dogs (mean age 14.7 months vs 40.9 months, p < .001).
- All LH dogs were treated with cementless stems; prophylactic cerclage was rarely used.

In Kershaw 2025 et al., on PSG vs AD, how many joint penetrations occurred in the PSG group during cadaveric screw placement?
🔍 Key Findings
- 3D-printed patient-specific guides (PSGs) significantly improved accuracy of drill hole entry (p < 0.001) and exit (p = 0.044) compared to commercial aiming devices (AD).
- Zero joint penetrations occurred with PSGs, whereas 3 of 7 AD-guided screws were predicted to penetrate the joint (p = 0.19).
- Variance in exit point and drill angle was significantly lower in PSG group, suggesting more consistent results.
- One PSG case failed due to improper guide seating, but this was corrected with improved soft tissue clearance.
- PSGs enabled safer trajectories despite use by novice surgeons, emphasizing their value in less experienced hands.
- Drill holes placed with ADs deviated more cranially and distally, increasing the risk of articular violation.
- Use of PSGs allowed for tighter clustering of drill trajectories, especially in the cranial–caudal axis.
- Subjective feedback favored PSGs for ease of use and ergonomic design, despite requiring slightly larger incisions.
