In Oramas 2025 et al., on laparoscopic liver lobectomy, what was the main advantage of the intrathoracic transdiaphragmatic trocar (ITT)?
🔍 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.

In Lomas 2025 et al., on hybrid THR in cats, what postoperative complication was **not observed** in any of the 17 hips treated?
🔍 Key Findings
- Hybrid THR in cats showed no major complications across 17 hips in 15 cats, including 2 bilateral cases.
- Postoperative radiographs confirmed stable implant positioning with no loosening, migration, or dislocation in follow-up imaging.
- Mean owner satisfaction was high, with a mean short-form feline musculoskeletal pain index (sf-FMPI) score of 2/36 at a mean follow-up of 438 days.
- SCFE (slipped capital femoral epiphysis) was the most common indication, seen in 13/17 hips.
- Partial tenotomy of rectus femoris origin resolved intraoperative medial patella luxation in 3 cases—no cats required surgical correction later.
- A micro BFX cup allowed for increased acetabular offset, possibly reducing luxation risk even when using a +0 femoral head offset.
- Hybrid THR was successfully used as a revision for failed CFX THR due to recurrent luxation—implants remained stable post-revision.
- Use of oversized cups (12 mm) with shallow seating or medial breach still resulted in stable outcomes, suggesting good implant fixation even with reduced bone stock.

In Mazdarani 2025 et al., on simulated muscle loading, which model showed the lowest muscle force ratios (quadriceps:gastrocnemius)?
🔍 Key Findings
- Simulated quadriceps and gastrocnemius forces increased proportionally with axial load in all three femoral fixation models.
- Model 2 (rigid fixation) resulted in subphysiologic quadriceps forces and abnormally high gastrocnemius forces, reducing model fidelity.
- Models 1 and 3 (with hip mobility) produced more physiologic quadriceps and force ratios, especially under 30–40% bodyweight loads.
- Force ratios were significantly lower in rigid fixation (Model 2) compared to hip-mobile models (p = .007), suggesting model design affects simulated muscle coordination.
- Joint angles (stifle and hock) remained within acceptable limits, though slight flexion occurred with increasing load.
- Relative foot position differed by ~3.9 mm between models 2 and 3, with model 2 showing a more caudal position.
- Model 3 preserved benefits of hip mobility while allowing radiographic documentation, making it a preferred setup for future studies.
- The study suggests that models used in feline stifle stabilization research may underestimate physiologic forces, especially with rigid fixation designs.

In Brincin 2023 et al., on radiographic follow-up post-MPL surgery, which factor was MOST strongly associated with a change in postoperative plan after MPL surgery?
🔍 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.

In Duffy 2022 et al., on barbed suture oversew, which repair method demonstrated the **shortest completion time** during oversew of the transverse staple line?
🔍 Key Findings
- Oversewing the transverse staple line using barbed suture showed no difference in initial (ILP) or maximum leakage pressure (MLP) compared to monofilament suture (p = .439 and .644).
- Barbed suture repairs were ~18% faster (25 seconds faster; p < .001) than monofilament suture.
- No difference was found between unidirectional and bidirectional barbed sutures in leakage resistance or repair time (p = .697).
- Mean ILP and MLP were significantly higher in control jejunal segments (6.6x and 5.1x greater respectively; p < .001).
- Leakage consistently occurred at the crotch of the FEESA in all oversew groups (>80%), not the staple line.
- All oversewn techniques leaked at supraphysiologic pressures, indicating clinical safety against in vivo leakage.
- No leakage was observed from barbed suture holes, addressing concerns of tissue trauma due to barb design.
- The study supports barbed suture as a viable alternative to conventional monofilament suture for FEESA oversew in dogs.

- Median time to contralateral CCLR was 12.9 months.
- Older age reduced risk — 2% decrease per month of age (p=0.003).
- Golden Retrievers and Labradors had significantly lower risk (p=0.028 and p=0.007, respectively).
- No effect found from TPA, meniscal injury, or comorbidities (e.g., hip dysplasia, hypothyroidism).

🔍 Key Findings
- Overall survival to discharge: 107 of 132 dogs (81%)
- Quartile improvement: Survival increased steadily from 67% in Q1 to 91% in Q4
- Q1: 22/33 survived
- Q2: 27/33
- Q3: 28/33
- Q4: 30/33
- Statistical significance: Higher operative rank significantly associated with improved survival (p < .05)
- Median cross clamp time (XCT): 73 min (range 40–165), but increased again in Q4
- Fatalities (n=25) were often due to:
- Failure to wean from CPB
- Intracranial vascular events (stroke)
- Intrathoracic hemorrhage
- Breed representation: CKCS (23.5%), Chihuahua (22%), Crossbreeds (21%)
- Stages of MMVD: Stage C (67%), Stage D (27%), Stage B2 (6%)
- Emphasis on deliberate multidisciplinary teamwork for outcome improvement
- Highlights importance of technical and non-technical team skills, procedural standardization, and consistent personnel

In Fracka 2023 et al., on patient-specific guides, what was a notable advantage of PSGs during surgery?
🔍 Key Findings
- 3D-printed patient-specific guides (PSGs) improved tibial cut alignment in the frontal plane compared to generic guides (mean error 1.03° vs 2.41°, p = .036).
- All tibial cuts using PSGs were within 3° of target alignment, while 2/8 of the generic group were outliers.
- PSGs significantly improved sagittal alignment of both distal (p = .018) and cranial (p = .043) femoral cuts.
- No significant difference was found in varus-valgus femoral alignment or closing angle between PSG and generic guide groups.
- Tibial sagittal slope alignment was not significantly different between groups.
- PSGs provided better intraoperative usability, including improved visibility, no loosening, and ease of use.
- Femoral sizing and component fit were equivalent between PSGs and generic guides, ensuring proper prosthesis alignment.
- PSGs may offer training advantages for novice surgeons, especially in anatomically complex or deformed joints.

In Burton 2025 et al., on antebrachial conformation, what was the interpretation of increased UCORA in dogs with HIF?
🔍 Key Findings
- PRUDA (proximal radio-ulnar divergence angle) and UCORA (ulnar center of rotation of angulation) were significantly greater in Cocker Spaniels with HIF vs those without.
- PRUDA (p < .001): Group 1 (HIF) vs Group 2 & 3.
- UCORA (p = .036): Group 1 vs Group 3.
- Other angles (MPRA, LDRA, PCRA, DCRA, torsion) showed no significant differences.
- Increased PRUDA and UCORA may lead to divergent load vectors across the humeral condyle, potentially predisposing to stress fracture (HIF).
- Measurement techniques using CT-based 3D reconstructions were reliable (intraobserver ICC > 0.84).
