🔍 Key Findings

• Arthroscopically assisted stabilization with an IAD was feasible in cadaveric canine shoulders using both bone anchor and suture-toggle techniques.
• Suture-toggle repair was successfully performed in all specimens, while bone anchors could not be deployed in 3/10 shoulders, indicating lower feasibility.
• Median surgical time was shorter for the suture-toggle group (25.5 min) compared to the anchor group (37.3 min).
• Postoperative abduction angles returned to baseline in the anchor group, while the suture-toggle group had slightly reduced angles, suggesting possible overtightening.
• Violation of the articular surface occurred in 2 anchor specimens and 1 suture-toggle specimen, but none were considered likely to be clinically significant.
• Overall targeting accuracy using the IAD was 88%, supporting its utility in guiding tunnel/anchor placement.
• CT measurements showed acceptable bone stock and insertion angles, but anchor insertion angles were lower than optimal for mechanical pullout strength.
• Suture-toggle technique was considered simpler and more consistent, with fewer complications and faster execution than anchor placement.

🔍 Key Findings

• HIF-affected dogs had significantly greater angle A and B, indicating increased axial articular angulation of the medial and lateral humeral condyle (p < .001).
• Vertical condylar height (lengths a and b) was significantly greater in HIF-affected dogs compared to controls (p = .007 and p < .001 respectively).
• Angle G (dorsal plane medial condyle angle) was also significantly greater in HIF-affected dogs, suggesting altered medial humeral morphology (p < .001).
• The angle between axial surfaces (A–B angle) was significantly more acute in HIF dogs (107.4° vs. 114.2°, p < .001), suggesting potential for increased shear force.
• Springer Spaniels with HIF showed significantly greater angulation and vertical height than unaffected Springer controls (p < .001 to .007 across variables).
• Morphological differences persisted across non-spaniel breeds, reinforcing that altered condylar geometry is not breed-restricted.
• Authors propose that greater condylar angulation contributes to shear stress, orthogonal to the fissure, possibly contributing to HIF pathogenesis.
• These morphologic alterations could inform future screening or preventive strategies, and may explain variable surgical outcomes and implant failure.

🔍 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

• Two-pin fixation had significantly greater strength (639 N) than single-pin fixation (426 N) in TTAF models (p = .003).
• Stiffness was also higher with two-pin constructs (72 N/mm vs 57 N/mm); statistically significant (p = .029).
• Both fixation types withstood loads greater than quadriceps force in dogs at a walk (240 N), indicating clinical viability.
• Failure was most commonly due to pin bending or pullout (82%), with fewer cases of ligament tearing or epiphyseal fracture.
• K-wire insertion angle (KWIA) did not significantly differ between fixation types (p = .13).
• Single larger pins delivered ~68% of the strength and ~83% of the stiffness of two smaller vertically aligned pins.
• Clinical implication: Two vertically aligned pins are biomechanically superior for TTAF fixation in canine models.
• Study used mature cadavers, which may underestimate loads and stiffness compared to immature clinical cases.

🔍 Key Findings

Study Design: Case series of 8 dogs with confirmed or suspected PJI after total hip replacement (THR)
Dogs were categorized into:

• Curative intent (CI) group (n=5): short-duration infections, implant retention attempted
• Non-curative intent (NCI) group (n=3): chronic infections, implants scheduled for removal or revision

Success Rate: 7 of 8 dogs had infection resolution, including 4 of 5 in the CI group
Sampling sensitivity:

• Arthroscopic culture success was 80% in the CI group but only 33% in the NCI group
• All explanted implants from NCI group yielded positive cultures

Common isolates: Staphylococcus pseudointermedius (including MRSP), S. epidermidis, Stenotrophomonas maltophilia, and E. coli
Ancillary treatments included:

• Partial synovectomy, high-volume lavage (5–10 L), biofilm-depleting lavage, and/or amikacin-impregnated calcium sulfate beads

Mean follow-up: >1 year (mean 812 days); no signs of recurrence in successfully treated cases
Conclusions: Arthroscopic management of THR infections is feasible and effective in appropriately selected dogs. Success aligns with human literature when infection type is favorable (Type 1, 3, 4). Sensitivity of arthroscopic culture is higher in early/acute infections.

🔍 Key Findings Summary

• Ex vivo cadaver study using 5 paired canine thoracic limbs
• Compared medial opening wedge osteotomy (MOWO) and external rotational osteotomy (ERO) of the humerus
• Measured pressure changes in the medial compartment using thin-film sensors
• ERO significantly reduced peak pressure and pressure distribution in the medial elbow compartment (p < 0.05)
• MOWO showed no significant pressure reduction relative to native state
• Combined MOWO + ERO did not significantly improve over ERO alone
• Findings support the biomechanical rationale for ERO as a surgical strategy to offload the medial compartment in cases like medial compartment disease (MCD)

🔍 Key Findings

• Routine follow-up radiographs after MPL surgery influenced management in only 3% of asymptomatic cases.
• Isolated radiographic abnormalities were rare (3.3%) and even less likely to alter treatment unless accompanied by clinical concerns.
• Dogs with both radiographic changes and clinical/owner concerns had 32× higher odds of a management change (OR 32.16, P < .001).
• Lameness, NSAID use, or prior unplanned visits significantly increased the odds of altered post-op plans.
• Owner-reported concerns alone led to a change in only 1.6% of cases without corroborating clinical findings.
• Radiographic follow-up was deemed unnecessary in dogs without owner concerns or abnormal physical findings.
• Hands-on clinical exam remains critical, though video-based rechecks may aid triage in uncomplicated cases.
• The study supports selective radiographic follow-up, reducing unnecessary imaging, stress, and clinician workload.

🔍 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

• 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 significant difference in initial leak pressure (ILP) among TA 30 V3 2.5 mm, TA 60 3.5 mm, and TA 60 4.8 mm stapler sizes (P = .78).
• All stapler types exceeded the physiological intraluminal pressure threshold (~25 mmHg), suggesting acceptable leak resistance.
• Mean ILPs: TA 30 V3 (181.5 mmHg), TA 60 3.5 mm (112 mmHg), TA 60 4.8 mm (77.2 mmHg).
• Leakage occurred at the staple line in 23 of 24 specimens; only one had ileal wall rupture.
• No correlation found between ILP and cadaver weight, cecal wall thickness, or cecal length.
• Cecal wall thickness averaged 4.9 mm, yet staple heights ranged only from 1.0–2.0 mm.
• One specimen in each TA 60 group leaked near or below physiologic pressures, suggesting rare outliers.
• Study supports clinical viability of all tested stapler sizes for canine typhlectomy, but highlights need for in vivo data on healing and complications.
