🔍 Key Findings

• Mean SI joint reduction was 94.25%, exceeding the 90% target considered important to reduce screw loosening
• Mean sacral width purchase was 82.52%, with all screws achieving >60%—a threshold for reducing implant loosening risk
• All 20 screws were accurately placed within the sacral body, confirmed via CT or radiographs
• A 3D-printed drill guide and table-bound system facilitated consistent screw placement via minimally invasive technique
• Craniocaudal and dorsoventral angles were well controlled (mean CCA = –1.22°, DVA = 0.71°), demonstrating accurate trajectory
• No intraoperative complications were reported; all pilot holes drilled on first attempt
• Use of fluoroscopy and orthogonal imaging enhanced surgical accuracy and reduced malposition risk
• The system permitted screw placement through a sleeve that doubled as a muscle retractor, allowing implant delivery without disruption

🔍 Key Findings

Synovitis was present in 100% of canine stifles with CCL disease (n = 163).

The most frequent severity score was 3/5 (55.2%), followed by 4/5 (24.5%).

Higher synovitis scores were significantly associated with:

• Higher median cartilage scores (p = .042, OR = 2.1 per unit increase)
• Longer duration of clinical signs (p < .001, OR = 1.27 per month)

Bodyweight (p = .083) and sex (p = .17) were not statistically significant in multivariable analysis.

Bucket handle meniscal tears were not associated with synovitis severity.

Clinical implication: Earlier intervention may help reduce synovitis and slow OA progression.

🔍 Key Findings

• Surgeon hand size significantly influences preferred finger-loop handle configuration when using laparoscopic instruments.
• Smaller-handed surgeons preferred smaller loop spacing and different finger placements, suggesting standard instrument designs may not accommodate all users.
• Larger-handed surgeons favored wider finger-loop spacing, which improved comfort and maneuverability during laparoscopic manipulation.
• Instrument ergonomics varied substantially between users, demonstrating that a “one-size-fits-all” laparoscopic handle design is suboptimal.
• Hand anthropometry affected both perceived comfort and functional performance during simulated laparoscopic tasks.
• Loop positioning and finger insertion pattern influenced wrist posture and grip mechanics, potentially affecting fatigue during prolonged procedures.
• Ergonomic mismatch between surgeon hand size and handle design may contribute to surgeon discomfort and reduced efficiency during minimally invasive surgery.
• The study supports development of adjustable or size-specific laparoscopic handles to improve surgeon ergonomics and operative performance.

🔍 Key Findings

• Double plate fixation significantly increased construct stiffness (563.7 vs 392.8 N/mm; p < .0001), supporting superior biomechanical stability
• Displacement was significantly reduced with double plating (−0.48 mm vs −0.81 mm; p < .0001), indicating improved resistance to cyclic loading
• No difference in primary plate strain between single and double constructs, suggesting load-sharing did not reduce plate stress
• Caudolateral placement of the second plate enhances biomechanical advantage by increasing moment arm and resisting tensile forces
• Cyclic loading model (7200 cycles) simulated 1 hour of walking, making findings clinically relevant to early postoperative activity
• Strain across fracture gap was lower in double plate constructs (~4.3% vs ~6.9%), supporting improved conditions for fracture healing
• No construct failures occurred, but actuator slippage occurred only in double plate group, highlighting potential testing/artifact considerations
• Clinical implication: double plating may allow earlier weightbearing and reduce need for external coaptation, improving recovery outcomes

🔍 Key Findings

• Lymphaticovenous anastomosis (TD to AV) was successfully performed in all 8 feline cadavers using a microvascular anastomotic coupler (MAC).
• Anastomotic patency was confirmed intraoperatively and postoperatively in 7/8 cats via contrast lymphography or retrograde venography.
• Dissection and anastomosis took a median of 120 minutes, with minimal technical complications.
• A 1.5 mm MAC was used in 6 cats, and a 2.0 mm in 2 cats; TD diameter ranged 1.0–1.5 mm, AV up to 2.25 mm.
• Challenges included vessel twisting and luminal patency issues, resolved intraoperatively with minor adjustments (e.g., repeat pinning, tacking suture).
• MAC use eliminated need for hand-suturing, lowering skill demands but requiring precise alignment.
• Technique provides direct lymphatic-to-venous drainage, potentially reducing the stimulus for collateral vessel formation.
• May serve as a future treatment option for feline idiopathic chylothorax, warranting further in vivo studies.

🔍 Key Findings Summary

• Primary 3.5-mm LCP used with short (SWL), medium (MWL), and long (LWL) working lengths
• Addition of orthogonal 2.7-mm LCP resulted in:
  • Significantly higher bending stiffness for SWL, MWL, and LWL (p < 0.0001)
  • Higher torsional stiffness for MWL and LWL (not for SWL)
  • Significantly lower strain across all working lengths in bending (p < 0.01)
• Working length inversely related to construct stiffness and directly to plate strain
• Orthogonal plates eliminated stiffness differences across working lengths in bending
• Suggests orthogonal plates can improve implant fatigue life and allow compensation when short working lengths are unachievable

🔍 Key Findings

• Cystoscopic-guided laser ablation (CLA) was associated with significantly fewer minor complications (13%) than neoureterostomy (100%) (P < .01)
• CLA resulted in significantly fewer recurrences of incontinence compared to neoureterostomy (0/7 vs 5/12; P < .05)
• 80% of dogs achieved continence within 1 month postoperatively, with a median continence score of 10
• Long-term continence was achieved in 88% of dogs, with or without adjunctive treatment, over a median of 66 months
• Major complications occurred in only 8% of dogs, and all were successfully managed with surgical revision
• Persistent ureteral remnants were seen only in neoureterostomy dogs, potentially contributing to incontinence recurrence
• All dogs with incontinence recurrence responded to medical treatment, while only 1/5 with persistent incontinence after surgery did
• CLA is recommended over open surgery for iEU correction, due to lower complication and recurrence rates

🔍 Key Findings

• All four techniques achieved TPA <14°, meeting the threshold for acceptable surgical correction in eTPA cases.
• Group A (CBLO + CCWO) and Group D (PTNWO) showed highest accuracy in achieving target TPA values.
• Group B (TPLO + CCWO) resulted in significant tibial shortening compared to other techniques.
• Group A caused the greatest cranial mechanical axis shift, while Group B caused the least.
• Group C (mCCWO) resulted in consistent under-correction of TPA, despite aiming for 0°.
• Modified or neutral wedge osteotomies (Groups C and D) had minimal effect on tibial length, making them suitable when preservation is important.
• All techniques involved mechanical axis shifts, highlighting the importance of preoperative planning to minimize morphologic disruption.
• Supplemental fixation was standard for all procedures to reduce risks such as tibial tuberosity fracture and plateau leveling loss.

🔍 Key Findings

• Cricoarytenoid lateralization (CAL) resulted in a significantly greater increase in rima glottidis area at both immediate (205%) and 15-day (199%) time points compared to thyroarytenoid lateralization (TAL) (152% and 127%, respectively).
• TAL group showed a significant reduction in rima glottidis area between immediate and 15-day postoperative measurements (P < .05), while CAL group had no significant reduction over time.
• No dogs in either group showed postoperative complications, including aspiration pneumonia, at the 15-day follow-up.
• All dogs showed improved clinical signs, including decreased stridor and increased exercise tolerance by day 15.
• CAL produced more stable postoperative glottic area, potentially due to preserved anatomical tension, whereas TAL might experience tension loss due to thyroid cartilage repositioning.
• Both procedures were technically effective and performed under the same protocol by a single board-certified surgeon.
• Endoscopic image analysis was used to quantify rima glottidis area, demonstrating a reliable objective method for surgical outcome assessment.
• Clinical outcome did not differ between groups, despite CAL showing a larger rima glottidis area.

🔍 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.
