🔍 Key Findings

• 20 cats with pelvic fractures treated with SOP plates and cortical screws
• Full function reported in all patients per FMPI follow-up
• Screw loosening in 3/20 SOP cases; implant removal in 3 cats
• Median sacral index decrease at follow-up: 5.7%; mostly mild narrowing
• Complications: 5 major (3 SOP removals, 2 trochanter osteotomy issues); 20 minor
• SOP plate shown feasible even in challenging configurations; good functional outcomes

🔍 Key Findings Summary

• F + P (forceps + plate compression) achieved the most uniform, high-pressure distribution across all quadrants.
• Kern forceps alone concentrated force in craniomedial quadrant, reducing caudal compression.
• Combining Kern + F improved craniolateral compression but did not restore caudal compression.
• Plate compression alone yielded caudal bias, not uniform pressure.
• Significant inter-method variation in quadrant-specific compression confirmed via ANOVA (p < 0.001 for all quadrants).

🔍 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.

🔍 Key Findings

• 14 joints from 7 cat cadavers underwent AA-HTS successfully.
• Median surgical time: 46.5 min (29–144), including 7 min for arthroscopy and 40 min for toggle placement.
• Intraoperative complications in 5/14 joints: 4 related to femoral tunnel creation, 1 toggle lodging.
• Toggle passage through femoral tunnel was the most challenging step, mildly difficult in 6 joints.
• Cartilage injury occurred in 10 joints, but all were minor (<10% of cartilage area).
• 13 deviations from planned technique were identified (8 major, 5 minor), all involving femoral tunnel placement.
• No neurovascular, intrapelvic, or major periarticular injuries occurred.
• Authors conclude: AA-HTS is feasible in cats, but associated with high rates of minor iatrogenic cartilage damage, intra-op complications, and technique deviations.

🔍 Key Findings

The study included 162 deep-pain-negative dogs undergoing decompressive surgery (hemilaminectomy) for acute thoracolumbar intervertebral disc extrusion (IVDE).

Ambulatory recovery occurred in 53.1% of dogs (86/162).

The best performing machine-learning model was XGBoost, with an AUC of 0.9502 and accuracy of 89.1%, outperforming Ridge, AdaBoost, and Naive Bayes models.

Preoperative-only XGBoost models were less accurate, with AUC dropping to 0.8271 and accuracy to 71.9%.

Top predictive features (by SHAP analysis) included:

1. T2-weighted to L2 spinal cord signal ratio (lower values predicted better outcome)
2. Use of fenestration (presence associated with better recovery)
3. Hospitalization duration
4. Imaging modality used
5. Duration of nonambulatory status

Machine learning provided better insight into prognostic factors than traditional statistical methods.

🔍 Key Findings

• LVSG was feasible in 9/10 feline cadavers and both live cats, with no intra- or postoperative complications in live cases.
• Two cadavers developed suspected stenosis due to staple lines too close to the lesser curvature; avoided with orogastric tube placement in later cases.
• No evidence of gastric leakage in any cadavers (8/10 tested) or live patients after methylene blue leak tests.
• Mean surgical time was ~110 min cadavers / 115 min live, and 27.6% of stomach mass was resected.
• Both live cats recovered uneventfully, lost 21–24% body weight over 3 months, and had no GI complications at 6-month follow-up.
• Orogastric tube and tension on the greater curvature were critical to avoid staple line misplacement or stenosis.
• No oversew of the staple line was needed, and unreinforced staples showed no leakage in live patients.
• Future studies needed to assess metabolic outcomes and ideal staple sizing and closure techniques.

🔍 Key Findings

• In an ex vivo study of 20 canine femur pairs, implantation of a novel hip resurfacing arthroplasty (HRA) prosthesis reduced maximum load (ML) by 22% and load at collapse (LC) by 27% vs. intact controls (p ≤ 0.05).
• Displacement at maximum load (DML), displacement at collapse (DC), and stiffness (k) were not significantly different between prosthesis and control groups.
• Both groups showed similar failure patterns, with 92% failing at the femoral neck.
• All prosthetic femurs still withstood ~6.2× body weight — exceeding estimated in vivo peak loads (~1.64× BW).
• Prosthesis positioning (neutral vs valgus) had no significant effect on biomechanical outcomes.
• Implant design preserved more metaphyseal bone stock than total hip replacement, possibly explaining the smaller load reduction compared to other short-stem prostheses.
• The press-fit cobalt–chromium design with conical stem allowed full contact and stress distribution over the femoral head/neck.
• Authors conclude the device has adequate immediate biomechanical strength for clinical use, though long-term in vivo studies are needed.

🔍 Key Findings

• Mean SI joint reduction was 94.25%, exceeding the 90% target considered important to reduce screw loosening
• Mean sacral width purchase was 82.52%, with all screws achieving >60%—a threshold for reducing implant loosening risk
• All 20 screws were accurately placed within the sacral body, confirmed via CT or radiographs
• A 3D-printed drill guide and table-bound system facilitated consistent screw placement via minimally invasive technique
• Craniocaudal and dorsoventral angles were well controlled (mean CCA = –1.22°, DVA = 0.71°), demonstrating accurate trajectory
• No intraoperative complications were reported; all pilot holes drilled on first attempt
• Use of fluoroscopy and orthogonal imaging enhanced surgical accuracy and reduced malposition risk
• The system permitted screw placement through a sleeve that doubled as a muscle retractor, allowing implant delivery without disruption

🔍 Key Findings

• Augmenting FEESA with two simple interrupted crotch sutures (TCS) or simple continuous crotch suture (SCCS) significantly increased initial leakage pressure (ILP) compared to no suture or a single suture (NCS, SICS).
• SCCS had the highest ILP (47.6 mm Hg), followed by TCS (37.8 mm Hg), SICS (33.0 mm Hg), and NCS (27.1 mm Hg).
• All crotch suture types increased maximal leakage pressure (MLP) compared to no crotch suture.
• Leakage from the crotch occurred most commonly in NCS (67%) and SICS (50%), but only 8% with TCS and 0% with SCCS.
• SCCS was the only technique where leakage never occurred at the crotch site.
• SCCS had the highest MLP (100.6 mm Hg), supporting its use in clinical settings with high-risk patients.
• Intraluminal pressures during leakage in NCS constructs were sometimes below normal physiologic pressures, emphasizing risk of leakage without crotch suture.
• The transverse staple line never leaked in any group, indicating the crotch is the primary weak point.
