🔍 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

• Near-infrared fluorescence cholangiography (NIRFC) was feasible and safe in all healthy dogs studied, with no major adverse effects noted.
• Low-dose ICG (0.05 mg/kg) at 3 h pre-op achieved the highest target-to-background (cystic duct-to-liver) contrast ratio, reaching nearly 4:1 at 280 minutes.
• Early imaging (time 0) favored low-dose ICG for optimal cystic duct visualization; high-dose ICG led to excessive liver fluorescence and reduced contrast.
• Visualization of biliary tree occurred within 10–20 min post-injection regardless of dose, but longer delays improved background clearance and contrast.
• No significant cardiovascular or histamine-related side effects were observed with either dose of ICG.
• Repeated ICG injections showed minimal residual fluorescence when using a >72 h washout period; shorter intervals caused mild carryover in high-dose groups.
• Surgeon scoring matched contrast ratios, confirming clinical relevance of imaging outcomes.
• Recommended dose for laparoscopic imaging: 0.05 mg/kg ICG given 3–5 h before surgery, or at premedication for urgent cases.

🔍 Key Findings

Design: Ex vivo cadaver study (n=8 dogs, 24 sites)
Comparison: Freehand vs. 3D-printed drill guide-assisted ventral slot (GAVS vs FHVS)
Findings:

• GAVS produced slots not significantly different from planned dimensions (p = .722–.875)
• FHVS produced significantly shorter slots than intended (p < .01)
• No difference in surgical time (p = .071)
• Shape ratio and slot divergence from midline were similar between groups (p > .4)
• Use of guide significantly reduced variability in slot position (63% → 29%), shape (65% → 24%), and divergence (54% → 50%)

Conclusion: 3D-printed guides improved accuracy and consistency of ventral slot creation by novice surgeons; supports future evaluation in live dogs and small breeds

🔍 Key Findings

• Modified subdural shunt (SDS) placement was adapted from prior techniques using a hemilaminectomy approach and no suturing of the dura or shunt.
• Dogs receiving SDS had significantly better long-term outcomes (85.7% improved) compared to those with durotomy alone (41.7%).
• Recurrence rate was lower in the SDS group (14.3%) than control (41.7%), though not statistically significant.
• Most recurrences occurred in Pugs (5/7), suggesting a breed predisposition.
• Shunt size was limited to 25% of spinal cord diameter, typically 3–3.5 Fr.
• CSF flow through the shunt was confirmed intraoperatively, supporting the role of SDS in maintaining flow and possibly preventing recurrence.
• Immediate postoperative outcomes were not different between groups (≈42% deteriorated), but long-term recovery was better with SDS.
• Steroid use pre-surgery did not correlate with improved outcome; fewer SDS dogs received steroids pre-op.

🔍 Key Findings Summary

• 3 dogs developed permanent fibular nerve dysfunction following TPLO
• Common findings:
  • Drill hole or screw in caudal tibial cortex just distal to osteotomy
  • Caudal malpositioning of TPLO plate (esp. right limb of case 3)
  • Post-op signs: cranial tibial atrophy, knuckling, exaggerated gait, no hock flexion
• One case had confirmed deep/superficial fibular neuropathy via electrodiagnostics
• Recommended prevention: avoid overly caudal drill paths; careful gait assessment at follow-up is key

🔍 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.

🔍 Key Findings

• No proximal femoral fractures occurred in any of the 184 hips with cerclage wire placement
• Cerclage wire was well tolerated, with no failures or complications related to the wire
• Application of a single cerclage wire took <10 minutes, was cost-effective, and required minimal instrumentation
• 3 postoperative complications (1 fissure, 2 fractures) occurred distal to the cerclage site, near the stem tip, requiring plate/screw fixation
• All dogs returned to normal activity, and all owners were satisfied with the outcome
• Cerclage placement location is critical—must be proximal to the lesser trochanter and close to the calcar to resist hoop strain
• Biomechanical evidence supports that cerclage wires improve resistance to hoop strain and subsidence of cementless stems
• Press-fit cementless stems may settle, but when supported by cerclage, this does not result in fractures even in undersized implants

🔍 Key Findings

• DPO significantly improved femoral head coverage, increasing mean DLS from 36.1% to 71.4% postoperatively (p < 0.001).
• No significant change in DLS between immediate postoperative and follow-up scans, suggesting stable surgical outcomes over time.
• Greater plate angle (30°) yielded larger DLS improvement (mean increase: 39.8%) compared to 25° and 20° plates.
• Only 3 hips had post-op DLS scores <55%, indicating most patients had lower risk of osteoarthritis progression.
• No correlation found between DLS improvement and age, body weight, or side of surgery, suggesting broad applicability.
• CT was used for DLS measurement in simulated weight-bearing, improving precision over radiographic methods.
• Major limitations included small sample size, multiple surgeons, and variable sedation vs anesthesia during imaging.
• DPO confirmed as effective for reducing dorsolateral subluxation, improving coxofemoral joint congruency in dysplastic dogs.

🔍 Key Findings Summary

• 22 dogs (36 shoulders) with shoulder OCD randomly assigned to COPLA scaffold (n=19) or Control (n=17) group
• At 6 months: Significantly fewer dogs in COPLA group had OA (14% vs. 67%; p = 0.019)
• At 1.5 years: OA prevalence increased in both groups with no significant difference (COPLA: 64%, Control: 60%)
• HCPI (pain index) increased significantly at 1 week post-op in COPLA dogs only (p = 0.001), but later normalized
• Static weight-bearing improved only in unilaterally operated COPLA limbs (p = 0.015)
• One dog in COPLA group had a fragment dislodge requiring arthroscopic removal
• Overall, COPLA scaffold may provide short-term benefit in OA reduction, but long-term outcomes were similar
