In Williams 2024 et al., on adrenaline use in maxillary nerve blocks, which of the following best describes the difference in surgeon-assessed hemorrhage scores between groups?
🔍 Key Findings
- The addition of adrenaline (0.00198%) to bilateral maxillary nerve blocks significantly reduced intraoperative hemorrhage in dogs undergoing sharp staphylectomy (median reduction: 77.1%).
- Normalized hemorrhage (g/kg) and total hemorrhage (g) were significantly lower in the adrenaline group (p = .021 and p = .013, respectively).
- Surgeon-assessed hemorrhage scores were also significantly lower in the adrenaline group (median 2 vs. 3; p = .029), indicating improved surgical visibility.
- No adverse effects (e.g. tachycardia, arrhythmia, or hypertension) were observed with adrenaline administration.
- A standardized intraoral approach to the maxillary nerve block was used with 0.5 mL per side regardless of dog size.
- Breed effect observed: English Bulldogs had higher normalized hemorrhage, possibly due to anatomical variation or underdosing relative to size.
- Adrenaline may also prolong local anesthetic action and reduce blood aspiration risks, though this was not directly measured.
- The study supports the routine inclusion of adrenaline in maxillary nerve blocks for staphylectomy in BOAS patients to improve surgical field and reduce bleeding.

In Trefny 2025 et al., on plate length and stiffness, which biomechanical testing method was used to measure stiffness and strain?
🔍 Key Findings
- 12-hole LCPs (80% plate–bone ratio) showed significantly higher construct stiffness than 6-, 8-, or 10-hole plates in both compression and tension bending.
- Strain on the plate was significantly lower in 12-hole vs 6-hole plates at all regions of interest (ROIs), especially around the fracture gap.
- No incremental increases in stiffness or decreases in strain were observed between 6-, 8-, and 10-hole plates—only when comparing to 12-hole plates.
- Bone model strain adjacent to the plate end was significantly lower for 10- and 12-hole plates vs 6-hole plates under both loading conditions.
- The threshold effect suggests biomechanical benefits only emerge beyond a plate–bone ratio of ~80%.
- Working length increased from 9.4 mm (6-hole) to 13 mm (others), potentially influencing strain/stiffness differences.
- Four-point bending was used, as it replicates the most biomechanically relevant force on plated long bones.
- Clinical implication: Longer plates may reduce plate strain and peri-implant bone strain, potentially lowering risk of fatigue failure or stress risers.

In Weaver 2026 et al., on Endo GIA stapler outcomes, what proportion of lung lobectomies had no intraoperative complications?
🔍 Key Findings
- Endo GIA staplers were successfully used in 46 lung lobectomies across 37 cases, including 33 dogs and 4 cats, representing the first in vivo clinical report of this stapler for open thoracic lung lobectomy.
- Most procedures had no intraoperative complications (82.6%), while minor complications occurred in 17.4%, primarily mild hemorrhage or air leakage.
- No major intraoperative complications were reported, and postoperative catastrophic events occurred in 4/37 cases (10.8%), likely related to underlying comorbidities rather than stapler failure.
- Short-term outcomes were excellent, with 97% of cases completing 14-day follow-up without complications aside from one seroma.
- Common indications for lung lobectomy included pulmonary masses, pulmonary bullae, abscess/granuloma, lung lobe torsion, trauma, and spontaneous pneumothorax.
- Endo GIA staplers provide simultaneous stapling and cutting, with articulation and 360° axial rotation, improving maneuverability in confined thoracic cavities.
- Tri-Staple technology deploys three staggered staple rows, which may improve sealing, reduce air leakage, and maintain tissue perfusion at the staple line.
- Overall complication rates were low, supporting the Endo GIA stapler as a safe alternative to traditional TA staplers for open lung lobectomy procedures.

In Eskelinen 2025 et al., on Plate–Pin fixation for MPL, what was the authors’ recommendation regarding the number of screws for TT fixation?
🔍 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 Scott 2025 et al., on acetabular cup revision, what revision approach was used in all cases?
🔍 Key Findings
Population: 9 dogs underwent revision of osteointegrated acetabular cups after total hip arthroplasty (THA)
Revision Indications:
- 7 luxations (5 ventral, 2 craniodorsal)
- 1 femoral stem fracture
- 1 aseptic stem loosening
Implants:
- 8 BFX cups, 1 Helica; all revised to BFX
- 7/9 required a larger cup than original
Cup removal: Required sectioning with a high-speed burr and modular osteotome; removal fragments extracted
Complications:
- 1 recurrent luxation
- 1 low-grade infection with possible metallic debris-associated osteolysis
- 2 femoral fissures managed intraoperatively
Outcomes:
- Good to excellent function in 6/6 dogs available at median 621 days
- Minimal complications with success in re-osteointegration of new cup
Clinical takeaway: Revision of stable, ingrown cups is feasible and offers an alternative to pelvic osteotomies; typically requires upsizing

In Adams 2024 et al., on canine tibial plateau fractures, what minor complication was observed postoperatively in Case 2?
🔍 Key Findings
- Tibial plateau fractures (TPF) are rare in dogs, but can be surgically stabilized with good outcomes even in complex trauma cases.
- Lateral TPFs (Unger type 41-B1) were approached via caudolateral arthrotomy, with elevation of the lateral meniscus for visualization and use of lag screws and K-wires for fixation.
- Medial TPF (Unger type 41-B2) was addressed via medial parapatellar approach using K-wires and a figure-of-eight tension band.
- One minor complication occurred: implant yield at 2 weeks in a case with a concurrent fibular fracture, resulting in a 0.8 mm step defect.
- No major complications were recorded, and all dogs achieved clinical union with full function by 8–10 weeks.
- Long-term owner-reported outcomes (LOAD scores) were excellent (5/52), indicating minimal osteoarthritis or chronic pain.
- Concurrent fibular fractures may increase risk of implant failure and should influence implant selection (e.g., considering buttress plating).
- Arthroscopic-assisted techniques may be applicable in select cases, but open reduction was preferred due to fragment displacement or concurrent injuries.

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.
