🔍 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

• Hybrid implants were used in older, heavier dogs with lower canal flare index (CFI) compared to cementless types.
• CFI <1.8 was associated with higher risk of femoral fracture or stem subsidence with cementless implants.
• Total complication rate was 14%, with catastrophic complications in only 1.5%—lower than reported in other studies.
• No significant difference in complication rates across implant types (BFX, BFX-C, hybrid).
• Femur fractures were rare (2.9%), lower than in prior studies, and successfully managed with cerclage/plate fixation.
• Coxofemoral luxation was the most common complication (8 cases); all occurred within 62 days post-op, mostly resolved with revision.
• Collared BFX stems did not significantly reduce complications, though they may limit stem subsidence.
• An implant selection algorithm was proposed, using age ≥7 years, weight ≥45 kg, and CFI <1.8 to guide cemented vs. cementless stem use.

🔍 Key Findings

• Compared unilateral plating (UP) vs orthogonal plating (OP) with 2.0, 2.4, and 3.0 mm plates (OP2.0, OP2.4, OP3.0).
• Model: acetal homopolymer (Delrin) rod with 29 mm fixed fracture gap, loaded axially (4–196 N, 90,000 cycles).
• OP constructs had 2.5–4.1x higher strength and 3.0–4.2x higher stiffness than UP constructs (p < .0002).
• UP had 3.5–4.1x higher gap strain than OP groups (p < .0075).
• All OP groups exceeded 1000 N max load before failure (vs 424 N for UP).
• Greater implant size in OP groups further increased performance.
• All constructs survived fatigue loading; 3.5 mm plates showed deformation, especially UP; OP plates remained intact.

🔍 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

🔍 Key Findings

• A positive meniscal flounce sign was associated with normal menisci in 95.5% of cases, demonstrating strong predictive value.
• Absence of the meniscal flounce sign was associated with meniscal tears in 92.7% of cases.
• Overall diagnostic accuracy of the flounce sign was 94.6%, with 96.6% sensitivity and 90.5% specificity.
• Most tears in flounce-negative stifles were bucket-handle tears (73.8%), while radial tears were present in some flounce-positive stifles.
• Radial tears did not consistently eliminate the flounce sign, suggesting they may not disrupt meniscal fiber tension sufficiently.
• All procedures were arthroscopically performed, with probing and visualization of the medial meniscus' caudal pole.
• Flounce sign should complement, not replace, probing—especially as some tear types (e.g., radial) may not abolish the sign.
• Limb positioning and joint distraction may affect flounce visibility, introducing minor observer variability.

🔍 Key Findings Summary

• Biomechanical study on 14 hindlimbs from Retrievers (cadaveric)
• Three stifle flexion angles tested: 125°, 135°, and 145°
• Contact Force Ratio (CFR) was significantly higher at 125° and 135° than at 145° (p < 0.001)
• Center of force shifted caudally with increasing flexion — especially in medial meniscus
• Lateral meniscus peak pressure was significantly higher at 125° than 145° (p = 0.049)
• Mean pressures on lateral meniscus decreased with extension, while medial meniscus pressure remained constant
• Relevance: Helps interpret meniscal load in early cruciate disease and in surgical modeling

🔍 Key Findings:

  • Excellent: 14
  • Good: 2
  • Poor: 2
• Long-term outcomes (18 cats):
  • Excellent: 15
  • Good: 1
  • Poor: 2

• Mean follow-up duration: Median 8 years.

🔍 Key Findings

• LVSG was feasible in 9/10 feline cadavers and both live cats, with no intra- or postoperative complications in live cases.
• Two cadavers developed suspected stenosis due to staple lines too close to the lesser curvature; avoided with orogastric tube placement in later cases.
• No evidence of gastric leakage in any cadavers (8/10 tested) or live patients after methylene blue leak tests.
• Mean surgical time was ~110 min cadavers / 115 min live, and 27.6% of stomach mass was resected.
• Both live cats recovered uneventfully, lost 21–24% body weight over 3 months, and had no GI complications at 6-month follow-up.
• Orogastric tube and tension on the greater curvature were critical to avoid staple line misplacement or stenosis.
• No oversew of the staple line was needed, and unreinforced staples showed no leakage in live patients.
• Future studies needed to assess metabolic outcomes and ideal staple sizing and closure techniques.

🔍 Key Findings

• All dogs developed progressive osteoarthritis (OA) after surgical debridement of proximal humeral OC.
• Ipsilateral muscle atrophy and reduced shoulder range of motion were common, particularly in unilaterally affected dogs.
• Arthroscopically, lesions showed incomplete cartilage infilling even years after surgery, averaging only ~37% infilling.
• Synovitis was present in all joints, with moderate-to-severe hypertrophy and vascularity scores.
• CT identified OC lesions as deeper and wider than radiography, and all affected joints had more advanced OA than contralateral limbs (P = .001 radiograph, P = .005 CT).
• Kinetic gait analysis showed no significant differences in peak vertical force or impulse, but a subtle 4.4% asymmetric load reduction on the operated limb.
• Median LOAD score was 6, indicating mild owner-perceived disability despite measurable clinical and imaging abnormalities.
• Cartilage infilling was incomplete in all cases, with no lesion exceeding 60% restoration, raising questions about the healing potential of debridement alone.

🔍 Key Findings Summary

• No significant difference in mechanical properties between contoured vs non-contoured SOP-LC rods
• Clamp configuration significantly influenced mechanical performance:
  • Single-side clamps → ↑ yield load, ↑ displacement, ↑ bending strength (p < 0.05)
  • Alternating-side clamps → ↑ initial torsional stiffness (p = 0.029)
• Clamp slippage was evident only in torsional tests; screw loosening may be torque-dependent
• Mild screw bending and construct offset suggest subtle instability
• Recommends clamp configuration choice based on loading scenario
• Suggests 3.0 Nm torque may be more effective than 2.5 Nm to prevent clamp slippage
