🔍 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

• No significant difference in peak load, failure load, stiffness, or 3 mm gap formation among bone tunnel types.
• Transverse tunnel (TT) constructs had 25% higher yield load than modified tunnels (MT) (P = .027).
• Most common failure mode was suture pull-through (67%), with no significant difference between groups.
• Gap formation ≥3 mm occurred in ~90% of constructs; no significant difference in force needed for gap among groups.
• All bone tunnel techniques (TT, VT, MT) are viable options for CCT reattachment in dogs.
• The 3-loop pulley (3LP) pattern provided strong, uniform repair, with higher loads to failure than previously reported.
• TT constructs showed more tendon distortion at the repair interface during loading.
• Inclusion of accessory tendon may have improved repair strength compared to prior studies using GT alone.

🔍 Key Findings

Case 1: Chest wall lift improved oxygenation (PaO₂ increased from 179.4 to 306.3 mmHg) and enabled thoracoscopic-assisted lobectomy in a cat with pleural effusion and pulmonary carcinoma.
Case 2: Chest wall lift using a Steinmann pin allowed 3-port thoracoscopic lobectomy for a bronchial foreign body; no complications observed.
Both cats: Lift increased working space and eliminated need for thoracotomy; no device-related complications.
Pretied ligating loops (PLL) were effective for hilar vessel ligation—preferred over staplers or self-locking ligatures in feline thorax.
Conclusion: Thoracic lift is a novel, minimally invasive method enhancing thoracoscopic procedures in small patients, particularly cats.

🔍 Key Findings

• Spinal stabilization with 3D-printed patient-specific drill guides (3D-PSGs) was safe, with no immediate perioperative complications reported.
• 84% of pedicle screws were optimally placed, and only 0.5% breached the spinal canal, reflecting high placement accuracy.
• 80% of dogs experienced no neurologic deterioration postoperatively, indicating reliable short-term safety.
• 3D-PSGs were accurate and reproducible, even across multiple institutions and surgeons.
• Mid-term outcomes were favorable: all dogs were ambulatory, and 90% had static or improved neurologic signs.
• 7 of 10 mid-term follow-ups showed abnormal gait, though owners rated lifestyle ≥3/5, suggesting acceptable function.
• 3D-printed guides enabled precise pedicle screw placement in deformed vertebrae, expanding options in small breeds.
• One dog suffered a T4 spinous process fracture due to overextension of PMMA cement, emphasizing the need for cement placement caution.

🔍 Key Findings

• No significant difference in cardiac troponin I levels 12h post-op between mDN and St. Thomas cardioplegia groups (p = 0.478)
• Sinus rhythm returned faster in the mDN group after aortic cross-clamp removal (median 60s vs 362s, p = 0.027)
• Lower serum potassium at cross-clamp removal in the mDN group (median 4.5 mEq/L vs 5.4, p = 0.005)
• Fewer doses needed in the mDN group (median 2.5 vs 4.0, p = 0.040)
• Higher total crystalloid volume used in mDN group (23.6 vs 12.6 mL/kg, p < 0.001)
• No difference in survival (700-day survival 90% in both groups, p = 0.958)
• No difference in hospitalization duration (median 6 days for both, p = 0.789)
• Echocardiographic remodeling similar between groups at 24h post-op

🔍 Key Findings

• Case: 9-year-old Labrador with a right caudal pulmonary adenocarcinoma.
• Technique: Peritumoral injection of indocyanine green (ICG) under VATS guidance, followed by near-infrared (NIR) imaging.
• SLN identified: Right tracheobronchial lymph node fluoresced and was safely extirpated.
• Histology: Grade 1 adenocarcinoma, pneumonia, reactive node.
• Outcome: Patient deteriorated and died on postoperative day 3 due to systemic complications (not linked to surgical technique).
• Clinical relevance: First clinical application of SLN mapping for canine pulmonary neoplasia; method feasible with open or minimally invasive approaches.

🔍 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

• Arthroscopic-assisted hip toggle stabilization (AA-HTS) was successfully completed in all 14 feline cadaver joints.
• Femoral and acetabular tunnel creation was feasible in all cases, though femoral tunnel placement had a higher rate of deviations.
• Intraoperative complications occurred in 5/14 joints, mostly related to femoral tunnel creation and toggle lodging.
• Minor articular cartilage injury (<10% total cartilage area) occurred in 10/14 joints, but no injury to neurovascular or intrapelvic structures.
• Thirteen surgical technique deviations (8 major, 5 minor) were identified in 7 joints, all involving the femoral tunnel.
• Toggle passage through the femoral tunnel was the most challenging step, being mildly difficult in 6 joints.
• Postoperative CT and gross dissection confirmed all toggles and buttons were in correct position, without damage to major surrounding structures.
• No deviations, complications, or cartilage injuries occurred in the last 4 joints, suggesting a learning curve effect.

🔍 Key Findings

• Lateral humeral condylar fractures (LHCF) were most common, comprising 63.6% of cases.
• Transcondylar screw (TCS) + K-wire(s) fixation had a 7.62x higher risk of major complications compared to other methods (p = .009).
• All cases of TCS migration occurred in the TCS + K-wire group; none occurred with plate fixation.
• Overall complication rate was 40.9%, with 29.5% being major and requiring intervention.
• Contralateral humeral intracondylar fissures (HIF) were found in 58.1% of French Bulldogs with CT data.
• No significant association between age and presence of HIF, but fissure length increased with age (R = 0.47, p = .048).
• Younger, lighter dogs had higher complication and screw migration rates, possibly due to softer bone and smaller condyles.
• TCS + plate fixation had the lowest complication rate, suggesting biomechanical superiority.
