In Kennedy 2024 et al., what was the closest average distance of the caudal portal to a major neurovascular structure?
🔍 Key Findings Summary
- 20 shoulders from 11 medium-to-large breed dogs evaluated
- Lateral portals used: middle arthroscopic, caudal instrument, cranial egress
- Musculotendinous lesions unavoidable, but small (18G needle); seen in deltoideus (90%), infraspinatus, teres minor, etc.
- Neurovascular safety:
- Caudal portal was closest to axillary artery/nerve branches (as close as 7 mm)
- Only 2/20 shoulders (10%) had omobrachial vein penetrated
- Cartilage injuries (IACI) occurred in 65%, primarily minor linear defects; use of guarded cannulas and distractors suggested for minimization
- Supports overall safety of lateral shoulder arthroscopy with portal placement awareness

In Hawker 2025 et al., on locking head inserts, why might LHI fail to reduce strain in LCP Combi-holes?
🔍 Key Findings
- Adding Locking Head Inserts (LHI) to a 3.5-mm LCP had no effect on plate strain, stiffness, or deformation in an open fracture gap model.
- Peak strain consistently occurred at the Combi-hole over the fracture gap, with values up to ~1837 µε.
- No significant difference in strain was found across configurations with 0, 3, or 9 LHI (p = 0.847).
- Construct stiffness and compressive displacement also remained unchanged regardless of LHI count (p = 0.311 and 0.069 respectively).
- Study contradicted the hypothesis that LHI would reduce strain and increase stiffness under biologic loading.
- Combi-hole design may limit the efficacy of LHI, as LHI only fill the locking portion, not the compression side where strain peaks.
- Implant fatigue risk remains highest over unfilled screw holes, especially over fracture sites—confirming previous failure patterns.
- Surgeons should consider alternative methods to reduce strain when facing high implant load scenarios.

In Jeon 2025 et al., on distal femoral shortening, what was the **median femoral shortening ratio** required to achieve prosthesis reduction?
🔍 Key Findings
- Distal femoral shortening osteotomy (DFSO) enabled prosthesis reduction in all 4 dogs with irreducible luxoid hips undergoing total hip replacement.
- Median femoral shortening ratio was 13.8% (range: 10.7–15.3%) based on intraoperative tension needed for prosthesis reduction.
- Bone union was achieved in all cases post-DFSO, indicating good healing potential.
- Two major complications occurred: one prosthetic luxation and one aseptic stem loosening requiring explantation.
- One intraoperative fracture of the greater trochanter occurred during trial reduction before DFSO.
- DFSO did not result in neurovascular injury, even in cases with significant femoral head displacement (>4 cm).
- Radiographic planning with FHD index and intraoperative assessment were crucial for determining DFSO necessity.
- DFSO avoids complications linked to subtrochanteric osteotomy by preserving proximal femoral anatomy and allowing secure distal fixation.

In Shetler 2022 et al., on radial head OCD, what was the main advantage of the lateral arthroscopic approach over the standard medial approach?
🔍 Key Findings
- Bilateral radial head OCD lesions were identified in a 6-month-old English Bulldog with elbow lameness.
- Medial arthroscopic portals allowed only partial visualization of radial head lesions, insufficient for treatment.
- Lateral arthroscopy portals provided excellent access for fragment removal and abrasion arthroplasty.
- Histopathology confirmed OCD, showing cartilage degeneration and retained cartilaginous cores.
- Dog showed complete resolution of lameness and no elbow pain at 5 months post-op.
- Lesions were caudolateral on the radial head, with discoid elevation of cartilage and clefts.
- Lateral approach avoids major neurovascular structures, reducing iatrogenic risk.
- The authors suggest lateral elbow arthroscopy may have broader indications, including for medial compartment disease or synovial biopsies.

In Scheuermann 2023 et al., on canine femoral MIPO, what was the most significant drawback observed with the use of the FRS?
🔍 Key Findings
- Precontoured plates using 3D-printed femoral models achieved near-anatomic alignment in all cadaver limbs.
- Fracture reduction system (FRS) required significantly fewer fluoroscopy images than intramedullary pin (IMP) methods (7 vs 26, P = .001).
- Despite longer surgical time (43 vs 29 minutes, P = .011), FRS showed equally accurate or better alignment compared to IMP.
- Femoral length, frontal, sagittal, and axial alignment were all within near-anatomic thresholds (<10 mm or <5° deviation) in both groups.
- FRS was associated with more consistent length maintenance, with IMP showing a median shortening of 2.3 mm (P = .03).
- Axial plane deviation was statistically different in the FRS group (P = .04), but still clinically acceptable.
- Study highlights potential for custom 3D-printed guides to reduce radiation exposure and improve precision in MIPO procedures.
- Authors caution that FRS was time-consuming and cumbersome, suggesting design refinements needed for clinical use.

In Araos 2024 et al., on helmet CPAP in brachycephalic postoperative dogs, which finding was true regarding SpO₂ following helmet CPAP use?
🔍 Key Findings
- CPAP at 5 cmH₂O via helmet significantly improved PaO₂/FiO₂ ratio in the early postoperative period of brachycephalic dogs, supporting enhanced pulmonary oxygen exchange (p = .04).
- CPAP had no significant effect on SpO₂ (p = .9), PaCO₂ (p = .18), or rectal temperature (p = .5).
- Helmet tolerance decreased over time, with 13 dogs withdrawn for intolerance (9 CPAP, 4 control) and 6 dogs withdrawn for airway compromise (5 control, 1 CPAP).
- CPAP group maintained PaO₂/FiO₂ ratios near or above 400 mmHg, while control dogs showed consistently lower values.
- Authors suggest PaO₂/FiO₂ is a more reliable oxygenation measure than SpO₂ for evaluating postoperative lung function.
- The study found no cases of hyperthermia; temperatures normalized over time in both groups.
- Arterial catheterization failed in several dogs, limiting blood gas analysis to a subset of the population.
- Authors recommend further studies focused on BOAS patients and exploring longer-duration CPAP use to assess impact on critical outcomes like tracheostomy rates or hospitalization.

In Mullins 2023 et al., on thoracolumbar pin placement, which grading outcome was **not** observed with either technique?
🔍 Key Findings
- Both free-hand probing (FHP) and 3D-printed guides (3DPG) enabled accurate spinal pin placement, with 87.5% vs 96.4% of pins graded as optimal (Grade I).
- 3DPGs had fewer intraoperative deviations (0/56 pins) compared to 6/56 with the FHP technique.
- No pins using either method fully breached the medial vertebral canal (Grade IIb) — a critical safety outcome.
- Pins placed using 3DPGs required less time overall (mean 2.6 min) than FHP (mean 4.5 min).
- FHP required specific experience and has a learning curve, whereas 3DPG use requires CAD software and 3D printing access.
- FHP had more lateral canal violations (Grade IIIa: 4/56 vs 0/56 for 3DPG), suggesting slightly less precision.
- Both techniques were safe, and all deviations were recognized and corrected intraoperatively.
- 3DPGs may offer practical advantages in clinical settings lacking surgical expertise, while FHP allows immediate intervention without 3D printing delay.
