In Paulick 2022 et al., on feline ilial plating, which failure mode occurred in **100% of specimens** using **nonlocking DCP plates**?
🔍 Key Findings
- Locking plates (except ALPS-5) withstood significantly more cycles before failure than nonlocking DCP constructs.
- ALPS-6.5, LCP, and FIXIN plates endured higher loads and resisted displacement better than DCP and ALPS-5.
- ALPS-5 plates showed lower bending stiffness than all other constructs (P < .05).
- DCP constructs failed due to screw loosening, seen in all specimens.
- Locking constructs failed by bone slicing, affecting 100% of specimens.
- Catastrophic implant failure (fracture or plastic deformation) occurred only in ALPS-5 group.
- Plate size and screw-plate interface both influence resistance to cyclic loading in feline ilial fracture repair.
- Locking plates are preferable for reducing screw pullout, but plate strength (e.g., cross-section) must match loading forces.

In Cantatore 2022 et al., on transanal submucosal resection, what proportion of dogs with recurrence were successfully treated with a repeat submucosal resection?
🔍 Key Findings
- Submucosal resection via a transanal approach was associated with a low rate (1.1%) of major complications and prolonged survival across benign and malignant rectal tumors.
- Overall recurrence rate was 21.5%, with higher recurrence in malignant tumors: 28.6% (carcinomas) and 30.4% (carcinoma in situ) vs. 13.6% (adenomas).
- Complications (P = .032) and incomplete margins (P = .023) were independently associated with increased recurrence risk.
- Recurrence was the only factor associated with increased risk of tumor-related death (P = .046).
- Repeat submucosal resection was successful in 60% of dogs with recurrence, indicating feasibility of this as a salvage approach.
- 1-, 2-, and 5-year survival rates for carcinomas were 95%, 89%, and 73%, though overall survival was significantly longer for benign tumors (P = .001).
- Preoperative diagnostics (FNA, biopsy) were often inconsistent with final histopathology – only 64.3% biopsy agreement.
- Presurgical imaging was not consistently performed, limiting accurate staging in many dogs.

In Heikkilä 2024 et al., on COPLA scaffold evaluation, what was the significant imaging-based outcome at 6 months in the COPLA group?
🔍 Key Findings Summary
- 22 dogs (36 shoulders) with shoulder OCD randomly assigned to COPLA scaffold (n=19) or Control (n=17) group
- At 6 months: Significantly fewer dogs in COPLA group had OA (14% vs. 67%; p = 0.019)
- At 1.5 years: OA prevalence increased in both groups with no significant difference (COPLA: 64%, Control: 60%)
- HCPI (pain index) increased significantly at 1 week post-op in COPLA dogs only (p = 0.001), but later normalized
- Static weight-bearing improved only in unilaterally operated COPLA limbs (p = 0.015)
- One dog in COPLA group had a fragment dislodge requiring arthroscopic removal
- Overall, COPLA scaffold may provide short-term benefit in OA reduction, but long-term outcomes were similar

In Silveira 2022 et al., on GTO in canine THR, how was the greater trochanter osteotomy (GTO) stabilized during surgery?
🔍 Key Findings
- GTO enabled successful cementless THR in dogs with severe medialization of the greater trochanter or chronic craniodorsal hip luxation.
- All 5 hips had acceptable long-term outcomes (median follow-up: 48 months) with full function and no persistent complications.
- Only one major complication occurred—a luxation unrelated to the GTO and successfully corrected with cup revision.
- GTO facilitated femoral canal access and gluteal preservation, reducing risk of iatrogenic injury during broaching.
- All GTOs healed radiographically (4 by 6 weeks, 1 by 12 weeks), with no cases of nonunion or implant migration.
- No complications related to GTO or PTBW fixation (pins + tension band) were observed in any dog.
- Surgical planning included templating both THR and GTO to ensure ideal alignment and reduce fracture risk.
- GTO may be especially valuable in luxoid hip dysplasia phenotypes or chronically fixed luxations.

In Chik 2024 et al., on cholangioscopy feasibility, what was the key limitation of using standard biopsy forceps through the disposable flexible endoscope?
🔍 Key Findings
- Open transcholecystic cholangioscopy was feasible using a 3.8 mm disposable flexible endoscope in all 8 canine cadavers.
- Visualization was consistently achieved up to the junction of the hepatic ducts, common bile duct, and cystic duct.
- Advancement past the junction was limited by the endoscope diameter (3.8 mm) and anatomical flexure.
- The 1.9 mm flexible ureteroscope could visualize the entire biliary tree, including the major duodenal papilla, in a large dog (43.8 kg).
- Endoscopic tools (e.g., 3 Fr grasping forceps) could be passed through the working channel only after removing the irrigation line.
- Standard biopsy forceps were incompatible with the disposable endoscope's 1.2 mm working channel.
- Cadaver study showed no rupture, but clinical extrapolation is limited due to lack of diseased tissue.
- Disposable endoscope setup cost (~$6,100) was significantly lower than traditional endoscopy systems (~$75,000–100,000), improving accessibility.

In Eskelinen 2025 et al., on Plate–Pin fixation for MPL, what was the rate of patellar luxation recurrence?
🔍 Key Findings
- Plate–Pin TTT fixation resolved MPL in 64/65 stifles with low recurrence (1.5%) and good lameness outcomes postoperatively.
- Complication rate was 21.5% (14/65 stifles), mostly minor (57%); major issues included pin migration, fracture, or capsular failure.
- Pin-related issues accounted for 8 of 20 total complications, highlighting implant refinement is needed.
- No avulsions, TT fixation failures, or luxation recurrence occurred in cases where surgical technique was followed precisely.
- Surgical deviations increased complication risk 11.3× (p < 0.05), suggesting adherence to protocol is critical.
- Single-session bilateral MPL surgery had comparable complication rate (3/20) to unilateral surgery (11/45).
- Screw breakage occurred in 3 cases, suggesting at least 3 screws may be needed for secure TT fixation.
- Authors suggest temporary pin fixation and later removal may reduce complications, though prospective studies are needed.

In Neal 2023 et al., on transcondylar screw placement, what was the main finding comparing trajectory angle between aiming device and fluoroscopy in right thoracic limbs?
🔍 Key Findings
- Aiming device provided comparable trajectory accuracy to fluoroscopy, especially in right limbs (1.9° vs. 3.4°, p = .0128).
- Eccentricity (deviation from condylar center) was lower with fluoroscopy (3.1 mm vs 4.2 mm, p = .0017), making fluoroscopy more precise.
- Odds of joint infringement were 8× higher with the aiming device, though not statistically significant (p = .0575).
- Residents had greater screw trajectory deviation than diplomates (p = .0366), highlighting impact of experience.
- Aiming device procedures took less time than fluoroscopy in some scenarios, particularly for right limbs with right-handed surgeons.
- Fluoroscopic procedures had more pin/drill attempts, increasing risk of glove puncture and potential aseptic breaks.
- Mean deviation angles in both groups (<3.5°) were within acceptable range to avoid intracondylar fracture gap.
- Cadaver model used large-breed, healthy adult dogs, not small-breed immature dogs, limiting generalizability.

In Quitzan 2022 et al., on staple line configuration, what was concluded about the vertical staple line?
🔍 Key Findings
- All FEESA configurations leaked at lower pressures than intact segments, confirming reduced integrity vs. native tissue.
- FEESA with 3-row transverse staples (3V/3T or 2V/3T) had significantly higher leak pressures than 2-row configurations.
- 3V/3T configuration had the highest ILP (69.88 ± 21.23 mmHg) among all groups, significantly greater than 2V/2T and 3V/2T (P < .001).
- Leakage consistently occurred at the transverse staple line (not vertical), regardless of configuration.
- No significant difference in maximum intraluminal pressure (MIP) between FEESA groups.
- All FEESA constructs withstood intraluminal pressures >25 mmHg, exceeding normal physiological jejunal pressure in dogs.
- No leaks occurred from the vertical staple line, highlighting it as a more robust closure site.
- Third staple row in transverse line may be a viable alternative to suture oversew, pending further clinical evaluation.

In Clough 2022 et al., on CBLO-TTT construct testing, what was the most common mode of failure in the CBLO-TTT specimens?
🔍 Key Findings
- Combined CBLO-TTT did not reduce load to failure compared to CBLO or TTT alone (P = .81 and P = .12, respectively).
- CBLO-TTT maintains construct strength without significant compromise compared to individual procedures.
- Most common failure mode in CBLO-TTT was displacement of the tibial crest segment with k-wire pullout and tension band untwisting.
- No fulcrum effect was seen in CBLO-TTT, unlike TPLO-TTT combinations, likely due to preservation of buttress effect.
- Patellar ligament avulsion occurred in both CBLO and CBLO-TTT, but not as a clinical concern — possibly artifact from cadaver model.
- Load-to-failure testing was static and unidirectional, not accounting for cyclic fatigue or in vivo healing.
- Plate size and saw blade variation were based on clinical realism, introducing potential variability but not affecting outcomes.
- Study suggests feasibility of simultaneous surgical correction of CCL rupture and MPL using CBLO-TTT in dogs.
