In Muroi 2024 et al., on radius plate stress effects, what was the yield load measured during mechanical testing of cadaveric radii?
🔍 Key Findings Summary
- Finite element analysis compared intact radii vs. locking plates placed 1 mm or 3 mm above the bone
- LP placement significantly reduced tensile (maximum principal) stress on cranial cortex, potentially causing implant-induced osteoporosis
- Shell element findings:
- Max principal stress significantly lower in both LP groups vs. intact (p < 0.05)
- Solid element findings:
- Equivalent stress higher and max principal stress lower in LP groups
- Implication: Tension reduction may impair bone remodeling; implant design and placement height affect stress environment

In Peycke 2022 et al., on CBLO in immature dogs, what was the most common **complication** from improper screw placement in CBLO?
🔍 Key Findings
- CBLO was effective for stifle stabilization in skeletally immature dogs with CrCL injuries, avoiding disruption of proximal tibial growth plates.
- Radiographic union of the osteotomy occurred in a mean of 6 weeks (range: 4–8 weeks), indicating rapid bone healing.
- Full limb function was restored in all cases by long-term follow-up (mean 23 months), including dogs with initial complications.
- Two dogs developed 19° valgus deformities due to screw interference with the proximal tibial physis; both were corrected surgically with return to function.
- One dog developed 10° recurvatum due to over-rotation of the tibial plateau, but retained full function without revision.
- CCS (countersink compression screw) caused early apophyseal closure in older dogs but had no adverse clinical effects.
- In contrast, K-wire or plate-only fixation preserved open apophysis, suggesting implant choice may influence growth.
- No meniscal injuries were observed, and all CrCL injuries were managed arthroscopically — 6 complete, 6 partial, 4 avulsions.

In Rocheleau 2023 et al., on shoulder stabilization, which complication was more common with bone anchor placement than with suture-toggle stabilization?
🔍 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 Horwood 2024 et al., on complications in luxoid hip dysplasia, what was the most common surgical revision performed for dorsal 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 Marchionatti 2022 et al., on antiseptic efficacy comparison, what issue may falsely elevate the observed efficacy of antiseptics in skin cultures?
🔍 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.

In Becker 2026 et al., on lumbar spine PLC biomechanics, how did the second PLC compare biomechanically to the first in terms of passive range of motion increase?
🔍 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 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 Miyagi 2025 et al., on endoscopic laser sphincterotomy, what was the outcome of the two cases with lateral perforation?
🔍 Key Findings
- Endoscopic-assisted retrograde catheterization (EARC) and laser sphincterotomy were successful in 18/18 cadavers, demonstrating technical feasibility.
- Intramural common bile duct (ICBD) length ranged from 10 to 21 mm (mean 15.8 mm), with no correlation to body weight (r = 0.06, p = .79).
- Transition from ICBD to extramural duct was accurately identified endoscopically in 88% (16/18); transition was heralded by separation of the submucosal layer.
- Partial lateral perforations occurred in 2/18 dogs, only during early learning phase; no leakage was found on open dissection.
- Laser sphincterotomy preserved the pancreatic duct orifice, aided by protective catheter positioning.
- Compared to open duodenotomy, this technique allows for a smaller incision and less manipulation of the pancreas, which may reduce morbidity.
- No adverse events such as intra-abdominal saline egress or full-thickness perforation occurred, and the technique allowed safe access up to 10 mm from the MDP.
- Cadaveric limitations included absence of biliary pathology and inability to evaluate live complications, but the technique shows promise for future live animal trials.

In Davey 2024 et al., on modified closed anal sacculectomy, what was the observed local recurrence rate following surgery?
🔍 Key Findings
- Modified closed anal sacculectomy resulted in a local recurrence rate of only 2.2%, substantially lower than prior reports (18–50%).
- Postoperative complications occurred in 31.9% of dogs; most (93%) were minor, with dehiscence being the most common.
- Mean survival time in deceased dogs was 521 days; median was 388 days.
- Surgical technique included complete en bloc excision of the sac and duct with sphincter reconstruction, aiming to reduce seeding risk.
- Only one major complication resulted in euthanasia due to infection and dehiscence.
- Histologic margins were complete in 44.7% of dogs; lymphatic invasion was present in 31.9%, and vascular in 8.5%.
- Adjunctive chemotherapy was administered in 34% of dogs (mostly carboplatin); not standardized due to retrospective design.
- Routine rectal exam was key to diagnosis in 57.4% of dogs with no clinical signs, underscoring the importance of screening.

In Carvajal 2025 et al., on femoral stem breakage, which patient factor was frequently present in failed cases?
🔍 Key Findings
Incidence of BFX lateral bolt stem breakage: 2.95% (13 dogs, 14 stems)
Implant factors:
- 13/14 were BFX lateral bolt stems (sizes #5–7)
- +9 necks used in 5/11 of 17 mm heads
- 10/14 stems undersized based on radiographs
- 10/13 dogs exceeded weight limits for implanted stem size
Malalignment:
- 10/14 had varus alignment (median 3.9°)
- 8/14 had insufficient proximodistal seating
Breakage site: Proximolateral shoulder in all cases
Revision outcomes:
- 11 revised (7 CFX, 3 larger BFX, 1 collared)
- 9/10 revised dogs regained full function
- Complications: 1 rebreakage, 1 periprosthetic fracture, 1 fixation failure
Histopathology:
- Electron microscopy showed fatigue striations and incomplete bead fusion
Conclusion: Avoid small BFX lateral bolt stems if undersized or if long necks required; use weight guidelines to prevent fatigue failure.
