In Dobberstein 2024 et al., on liver biopsy forceps, which biopsy technique showed good diagnostic agreement between 3 mm and 5 mm samples?
🔍 Key Findings Summary
- Subjects: 12 healthy colony cats, 68 total liver samples collected via laparoscopy
- Biopsy instruments: 3 mm vs 5 mm Storz Blakesley cup forceps
- Techniques: Twist (T), Pull (P), Twist + Pull (TP)
- Results:
- 5 mm forceps yielded significantly more hepatic lobules (mean 12.4 vs 4.9), portal triads (29.6 vs 19.0), weight, and histologic area (p < .01)
- T and P techniques yielded more portal triads and lobules than TP (p = .003 and p = .015)
- TP technique resulted in greater tissue crush vs T (p = .01)
- Good diagnostic agreement between 3 mm and 5 mm samples only with TP (κ = 0.75)
- All samples were of sufficient diagnostic quality, despite size or technique
- Clinical implication: Both 3 mm and 5 mm forceps are viable; further studies are needed to confirm diagnostic accuracy of 3 mm samples

In Dalton 2023 et al., In Minimally invasive acetabular fracture repair in dogs, what was the median total surgical time for the cadaveric minimally invasive acetabular fracture repairs?
🔍 Key Findings
- Feasibility study in 5 canine cadavers plus 1 clinical case (Chihuahua, 5.5 kg).
- Technique used two small approaches (caudal and craniolateral) connected with an epiperiosteal tunnel.
- Plates were precontoured on mirrored 3D-printed hemipelves to improve fit and reduce intraoperative bending.
- Cadaver outcomes: fracture gap <2 mm, step defect <1 mm, pelvic angulation <5°.
- Sciatic nerve injury was minimal: 1/5 cadavers had a mild indentation; others had no gross injury.
- Median total surgical time: ~46 minutes in cadavers; incisions ~5 cm.
- Clinical Chihuahua case: weight-bearing within 24 hrs, radiographic union at 3 months; one screw fractured but no adverse effect.
- Authors conclude: MIAF with 3D printing is feasible and accurate, but requires further evaluation before routine use.

In McCagherty 2025 et al., on WID detection accuracy, what was the main type of bacterial population detected in most wound infections?
🔍 Key Findings
- Bacterial fluorescence was detected in all wounds (17 dogs, 4 cats) using the point-of-care wound imaging device (WID).
- The WID confirmed the presence of clinically relevant wound infection in all evaluated cases at the time of imaging.
- No significant difference was found in bacterial yield or burden between image-guided and non-guided swabs (QBC and PCR; p > 0.05).
- The WID helped guide wound debridement in some cases by localizing areas of fluorescence, especially in necrotic tissue.
- Most infections were polymicrobial and dominated by anaerobes, highlighting the need for anaerobic culture inclusion.
- PCR analysis showed low bacterial DNA yields, often complicated by host DNA contamination, limiting its utility.
- The study did not evaluate sensitivity/specificity of WID, as only fluorescence-positive wounds were included.
- Clinical utility of WID lies in immediate visual confirmation of infection, supporting timely antimicrobial treatment decisions.

In Payne 2024 et al., on HIF propagation pattern, what was the typical origin point of the humeral intracondylar fissure (HIF) in English Springer Spaniels?
🔍 Key Findings Summary
- HIF typically originates 57° caudal to the supratrochlear foramen and propagates cranially in a segmental pattern.
- %HIF correlated significantly with both fissure depth and length:
- %DHIF increased linearly (r = 0.989, p < 0.001)
- %LHIF followed a sigmoidal relationship with %HIF (p < 0.001)
- Higher %HIF was significantly associated with:
- Clinical lameness (p = 0.004)
- Distal shift in the fissure center (CHIF)
- Implant complications in 5/17 elbows treated with transcondylar screws
- Isthmus diameter increased with weight (p = 0.002), relevant for screw sizing

In Espinel Rupérez 2023 et al., on hip toggle stabilization, what was the most challenging step reported during the procedure?
🔍 Key Findings
- Arthroscopic-assisted hip toggle stabilization (AA-HTS) was successfully completed in all 14 feline cadaver joints.
- Femoral and acetabular tunnel creation was feasible in all cases, though femoral tunnel placement had a higher rate of deviations.
- Intraoperative complications occurred in 5/14 joints, mostly related to femoral tunnel creation and toggle lodging.
- Minor articular cartilage injury (<10% total cartilage area) occurred in 10/14 joints, but no injury to neurovascular or intrapelvic structures.
- Thirteen surgical technique deviations (8 major, 5 minor) were identified in 7 joints, all involving the femoral tunnel.
- Toggle passage through the femoral tunnel was the most challenging step, being mildly difficult in 6 joints.
- Postoperative CT and gross dissection confirmed all toggles and buttons were in correct position, without damage to major surrounding structures.
- No deviations, complications, or cartilage injuries occurred in the last 4 joints, suggesting a learning curve effect.

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 Miller 2024 et al., on staple vs. hand-sewn feline GI techniques, which construct had equivalent leak pressure to hand-sewn anastomosis but with significantly reduced completion time?
🔍 Key Findings
- Skin staple anastomosis (SSA) had comparable leak pressures to hand-sewn anastomosis (HSA) but required half the time to complete.
- Skin staple enterotomy (SSE) had significantly lower leak pressures than hand-sewn enterotomy (HSE) and failed in 12/20 constructs during pressure testing.
- HSE constructs took 8× longer to complete than SSE, but had much higher intraluminal pressure tolerance.
- All SSE constructs leaked from the center, with 35% leaking immediately and 60% showing catastrophic failure.
- SSA leakage occurred at the center in 40% of constructs, likely due to a learning curve in early samples.
- All constructs had higher pressures than normal physiologic intestinal pressure (4.0 mmHg ±2.0), except some SSEs with immediate leaks.
- Authors recommend SSA as a viable alternative with appropriate training but do not recommend SSE using the tested technique in live cats.
- Staple size and placement technique are key factors; smaller or more precisely placed staples may reduce leak risk.

In Petchell 2025 et al., on CORA-based CCWO, what is the primary purpose of plotting both PMA and DMA lines in the CCWOCORA technique?
🔍 Key Findings
- The CORA-based cranial closing wedge ostectomy (CCWOCORA) consistently achieved the target postoperative TPA of 5° across all tibial morphologies.
- CCWOCORA produced significantly less variability in postoperative TPA compared to other methods (TPA range: 5.00–5.00°; p < .001).
- Mechanical axis advancement (MAA) was precisely controlled at 3° in CCWOCORA, leading to greater surgical predictability.
- Other techniques (e.g., CCWOTPA, CCWOTPA–5, CCWOISO) showed greater variance in TPA, MAA, and tibial length.
- In small-breed dogs, increasing the MAA from 3° to 5° did not affect TPA outcomes, but increased proximal bone stock, improving feasibility.
- Wedge angles and tibial length changes varied by method, but CCWOCORA maintained length better than TPA-based methods.
- The technique allows preoperative planning of both desired MAA and TPA, enhancing predictability and customization.
- CORA methodology enables precise geometric correction and alignment of mechanical axes, reducing reliance on trial-and-error alignment.
