🔍 Key Findings

• Minimally invasive fluoroscopic technique yielded median reduction of 94.1% immediately postoperative.
• Screw purchase ≥60% in sacral body achieved in 82% of cases, with median purchase of 73.3%.
• One screw exited caudally; no dorsal, ventral, or cranial exits reported.
• At 7-week follow-up, reduction and purchase slightly declined but remained effective (p = .008 and p = .013).
• No screw loosening observed, even in suboptimal reductions or purchases.
• Pelvic canal width and symmetry (PCDR and HCWR) were restored and maintained.
• Excellent long-term function: FMPI ≥0.98 in 9 of 10 cats; owners reported 10/10 satisfaction.
• Fluoroscopy enabled accurate screw placement and minimized tissue trauma, contributing to rapid recovery.

🔍 Key Findings

• Study Design: Cadaveric model using four large-breed dogs with 10x10 cm full-thickness wounds at four locations (shoulder, thorax, flank, thigh).
• Configurations Tested: Diagonal, opposite, parallel, and perpendicular placements of wound infusion catheter and JP drain.
• Fluid Retrieval:
  • No significant difference by configuration (p = .92) or location (p = .32).
  • Perpendicular configuration had the highest mean retrieval (11.35 mL, 56.8% of instilled volume).
  • Flank location had the lowest retrieval (7.2 mL, 35.9%).
• Surface Area Coverage:
  • Parallel configuration achieved the highest SA coverage (83.4% ± 11.6%, p < .01).
  • Perpendicular was lowest.
• Leakage:
  • No difference in leakage between configurations (p = .74) or locations (p = .10).
  • Leakage commonly occurred at drain or catheter entry points (93.8% of wounds).
• Conclusion: Parallel drain configuration optimized fluid dispersion. Infusion-retrieval systems may allow for topical therapy delivery in closed wounds.

🔍 Key Findings

• Refracture occurred in 5.5% of limbs, with higher incidence in the plate removal group (12.5%) vs. non-removal (3.5%).
• In the non-plate removal group, refractures occurred at the most distal screw site, linked to greater screw position change during growth (OR 1.79, p=0.04).
• Screw-to-bone diameter ratio (SBDR) >0.4 was a significant risk factor for refracture in the plate retention group.
• In the plate removal group, refractures occurred at the original fracture site, associated with lower pixel value ratio (bone mineral density) and reduced radial thickness.
• Implant-induced osteoporosis (IIO) beneath the plate likely contributed to refracture risk after plate removal.
• Younger age at fracture (<6 months) was associated with higher refracture risk due to ongoing radial growth and shifting screw position.
• No significant association was found between refracture and plate type (locking vs conventional), fixation method, or ulnar union.
• Recommendations include careful SBDR sizing, motion restriction, and cautious plate removal decisions in growing dogs.

🔍 Key Findings

• 3D-printed patient-specific guides (PSGs) significantly improved accuracy of drill hole entry (p < 0.001) and exit (p = 0.044) compared to commercial aiming devices (AD).
• Zero joint penetrations occurred with PSGs, whereas 3 of 7 AD-guided screws were predicted to penetrate the joint (p = 0.19).
• Variance in exit point and drill angle was significantly lower in PSG group, suggesting more consistent results.
• One PSG case failed due to improper guide seating, but this was corrected with improved soft tissue clearance.
• PSGs enabled safer trajectories despite use by novice surgeons, emphasizing their value in less experienced hands.
• Drill holes placed with ADs deviated more cranially and distally, increasing the risk of articular violation.
• Use of PSGs allowed for tighter clustering of drill trajectories, especially in the cranial–caudal axis.
• Subjective feedback favored PSGs for ease of use and ergonomic design, despite requiring slightly larger incisions.

🔍 Key Findings

• Biocurve TPLO plate generated the highest and most uniform interfragmentary compression, particularly in the cranial quadrants (Q1: 0.285 MPa; Q2: 0.304 MPa), due to its opposing angled dynamic compression holes.
• Synthes TPLO plate produced the lowest compression across all quadrants (0.050–0.111 MPa), remaining within the low compression range.
• Arthrex plate achieved intermediate compression, with high compression in the craniolateral quadrant (Q2: 0.292 MPa) but only moderate compression elsewhere.
• Plate design significantly affected compression distribution (p < 0.001), confirming that screw hole orientation and plate geometry influence osteotomy compression patterns.
• Cranial compression (Q1–Q2) was greatest with the Biocurve plate, potentially improving stability against “rock-back” or loss of tibial plateau angle.
• No significant differences between plates were found in caudal quadrants (Q3–Q4), suggesting plate design primarily affects cranial compression.
• Pressure-sensitive film analysis allowed quantitative mapping of compression patterns, dividing the osteotomy interface into four quadrants for standardized comparison.
• Clinical superiority of one plate was not concluded, but findings suggest plate geometry and dynamic compression hole orientation influence mechanical stability during TPLO fixation.

🔍 Key Findings

• All dogs (11/11) showed improved radiohumeral articulation postoperatively, confirmed arthroscopically.
• Median shortening: radioulnar (3.2 mm), humeroradial (1.8 mm), humeroulnar (1.2 mm).
• Median lameness score improved from 2/4 to 1/4 by final follow-up.
• Bone healing achieved in a median of 8 weeks (range: 4–14 weeks).
• No major complications; minor issues included 1 screw loosening and 1 superficial infection.
• Subjective function was graded full in 4 dogs, acceptable in 7.
• Arthroscopy enabled accurate dynamic joint assessment, preferred over static radiographs.
• Use of both orthopedic wire and plating provided secure fixation and improved outcomes.

🔍 Key Findings

• Bending tees significantly increased mediolateral bending stiffness, but not craniocaudal stiffness, in plate-bone constructs.
• Mean mediolateral stiffness was 43.2 N/mm with tees vs. 41.1 N/mm without (p = 0.0042), though the absolute difference was small.
• No significant differences were found in craniocaudal bending stiffness between constructs with or without tees (p = 0.89).
• Plastic deformation occurred in all constructs; no screw pull-out or implant breakage was observed.
• SOP nodes may resist compressive but not tensile deformation, suggesting variable mechanical contributions depending on loading direction.
• Craniocaudal bending had greater stiffness than mediolateral due to higher area moment of inertia along the node diameter.
• Clinical relevance of added stiffness from tees remains unclear, warranting further in vivo and cyclic testing.
• This was the first study to directly test SOP constructs with/without tees over a fracture gap in multiple planes.

🔍 Key Findings Summary

• Prevalence of contralateral CCLR in dogs ≥8 years and ≥15kg was 19.1%, notably lower than previous studies (33–50%).
• Median time to contralateral CCLR was 12.9 months.
• Older age reduced risk — 2% decrease per month of age (p=0.003).
• Golden Retrievers and Labradors had significantly lower risk (p=0.028 and p=0.007, respectively).
• No effect found from TPA, meniscal injury, or comorbidities (e.g., hip dysplasia, hypothyroidism).

🔍 Key Findings

• CT localization of liver masses was more accurate by division (88%) than by lobe (74.3%)
• Inter-radiologist agreement was excellent for division (kappa up to 0.885) and only moderate–good for lobe
• Quadrate and right lateral lobes had significantly lower localization accuracy compared to left lateral or medial lobes
• CT localization of the left division was most accurate (90.1%) compared to central (77.1%) and right (88.3%)
• Portal and hepatic venous phases were equally helpful for localization (each ~30–38% usefulness)
• No significant associations found between histopathologic diagnosis and localization accuracy
• Lobe-level CT localization should be interpreted with caution, especially for the quadrate and right lateral lobes
• Radiologist experience likely influenced accuracy, with the most experienced radiologist performing best
