In Socha 2024 et al., what was the statistical significance of the difference in T2*L values between CrCL and CdCL?
🔍 Key Findings Summary
- Normative ultrashort echo time (UTE) MRI T2* values were established for:
- Patellar ligament (PL): T2*L = 4.65 ms
- Cranial cruciate ligament (CrCL): T2*L = 5.99 ms
- Caudal cruciate ligament (CdCL): T2*L = 7.06 ms
- Statistically significant differences in T2*L values were found between:
- PL vs. CrCL (p = 0.03)
- PL vs. CdCL (p = 0.0097)
- CrCL vs. CdCL (p = 0.03)
- No significant differences in short T2* (T2*S) values across ligaments.
- Study highlights potential of UTE MRI to detect early ligament changes even without physical instability.
- May guide early diagnosis in partial CrCL rupture where standard MRI is limited.

In Parlier 2024 et al., on insufflation effects on portal pressure in dogs, what was the observed change in portal pressure at 14 mmHg insufflation?
🔍 Key Findings
- Portal pressure increased proportionally with insufflation pressure: 38% at 6 mmHg, 95% at 10 mmHg, and 175% at 14 mmHg.
- Exponential model: average increase of 7.45% per mmHg of insufflation pressure (CI: 4.7–10.2%).
- No systemic hemodynamic adverse effects were observed; MAP remained >60 mmHg throughout.
- Portal hypertension threshold (15 mmHg) predicted at ~6.4 mmHg insufflation pressure.
- No statistical impact from patient weight, pressure-to-weight ratio, or order of insufflation rounds.
- Measurement technique was feasible and safe, with only minor challenges (e.g., catheter kinking).
- The study supports use of the lowest insufflation pressure needed for visualization to avoid portal hypertension.
- Baseline portal pressures returned after desufflation, supporting comparison pre- and post-attenuation.

In Welsh 2025 et al., on orthogonal plating, how did unilateral plating compare to orthogonal plating?
🔍 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.

In Gomes 2025 et al., on subdural shunting for TL-AD, what was the significant long-term outcome of SDS placement compared to durotomy alone?
🔍 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.

In Filho 2024 et al., what was the %BW carried by the contralateral limb in low forelimb amputees?
🔍 Key Findings Summary
- 39 dogs (mostly post-trauma) with either forelimb or hindlimb amputations (high vs low)
- No significant difference in %BW distribution between high vs low forelimb amputations
- In hindlimb amputees:
- High amputations → more overload on contralateral hindlimb (p = 0.01)
- Low amputations → more even load split, slight preference for contralateral hindlimb and ipsilateral forelimb
- Values derived from pressure-sensitive walkway confirmed with statistical significance
- Useful implications for prosthesis selection and rehabilitation planning

In Hoenecke 2025 et al., on radiographic opacity in patella luxation, what percentage of dogs with long-term follow-up developed subsequent CCL rupture?
🔍 Key Findings
- 65% of stifles with patella luxation and intact CCLs had increased radiographic soft tissue opacity
- Weight and radiographic OA were significantly associated with increased opacity (p = .0029 and p = .0143)
- Each 1 kg increase in weight increased the odds of opacity by 10%
- Grade of patella luxation, age, and muscle atrophy were not significantly associated with increased opacity
- 19% of dogs with long-term follow-up developed a CCL rupture post-patella surgery, 50% of those had opacity at initial presentation
- Radiographic opacity alone should not be interpreted as CCL disease in dogs with patella luxation
- Radiographic findings likely represent effusion or synovial hyperplasia, not CCL pathology
- Arthrotomy was used to confirm CCL integrity at surgery, but arthroscopy could provide better sensitivity

In González Montaño 2023 et al., on traumatic pulmonary pseudocysts (TPP), what was the most common concurrent thoracic injury in patients with traumatic pulmonary pseudocysts?
🔍 Key Findings
- Traumatic pulmonary pseudocysts (TPP) were diagnosed in 11 patients (9 dogs, 2 cats) using CT after blunt trauma.
- TPPs were identified on radiographs in 64% of cases that were CT-confirmed, highlighting the superior sensitivity of CT.
- Most cases (7/10) were managed conservatively, with complete recovery and no TPP-related mortality.
- Thoracic surgery (lung lobectomy) was performed in 3 dogs, due to persistent pneumothorax or large TPP with perceived risk of complications.
- All pneumothorax cases were managed with thoracostomy tubes, and chest drains were used in 73% of cases.
- Pneumothorax was present in 100% of patients, often bilateral, and pulmonary contusions were reported in 73%.
- One cat was euthanized due to unrelated maxillofacial trauma; no deaths were attributed to TPP itself.
- Long-term follow-up (median 768 days) revealed only 1 case with possible TPP-related pneumonia; others had no complications.

In Oramas 2025 et al., on laparoscopic liver lobectomy, how many right lateral liver lobectomies were successfully performed?
🔍 Key Findings
- 13 cadaver dogs underwent laparoscopic right lateral liver lobectomy in sternal recumbency using a transdiaphragmatic intrathoracic trocar (ITT).
- All lobectomies were successful, regardless of dog size.
- Median total surgical time: 35.5 min; median lobectomy time: 18.5 min.
- ITT port enhanced visualization and access to hilus.
- No correlation between body weight and hilus access (p = .78).
- Stronger correlation between liver lobe weight and lobectomy time (r = .73, p = .004).
- Complication in 3/13 cases: Loss of insufflation due to balloon-tip port failure and pneumothorax.
- Recommendation: Use a new balloon trocar per case in clinical applications to prevent failure.

🔍 Key Findings Summary
- Cadaveric study using 3 miniature breed dogs (6 hemipelves) to assess spinal neuronavigation accuracy for lumbar plate fixation
- 20 screws placed using CBCT-based navigation with real-time tracking
