In Perez Neto 2025 et al., on hip resurfacing arthroplasty, what was the most common site of failure in both groups?
🔍 Key Findings
- In an ex vivo study of 20 canine femur pairs, implantation of a novel hip resurfacing arthroplasty (HRA) prosthesis reduced maximum load (ML) by 22% and load at collapse (LC) by 27% vs. intact controls (p ≤ 0.05).
- Displacement at maximum load (DML), displacement at collapse (DC), and stiffness (k) were not significantly different between prosthesis and control groups.
- Both groups showed similar failure patterns, with 92% failing at the femoral neck.
- All prosthetic femurs still withstood ~6.2× body weight — exceeding estimated in vivo peak loads (~1.64× BW).
- Prosthesis positioning (neutral vs valgus) had no significant effect on biomechanical outcomes.
- Implant design preserved more metaphyseal bone stock than total hip replacement, possibly explaining the smaller load reduction compared to other short-stem prostheses.
- The press-fit cobalt–chromium design with conical stem allowed full contact and stress distribution over the femoral head/neck.
- Authors conclude the device has adequate immediate biomechanical strength for clinical use, though long-term in vivo studies are needed.

In Viitanen 2023 et al., on zygomatic sialoadenectomy, which dog conformation was associated with higher difficulty in complete gland removal using IOA?
🔍 Key Findings
- Intraoral approach (IOA) reduced surgical time compared to lateral orbitotomy (median: 42.0 vs 65.7 minutes, p = .005)
- Ease of closure (Stage III) was better with IOA (p < .001), though gland removal (Stage II) was easier with LOA (p = .039)
- Complete gland removal was achieved in 8/10 IOA vs 10/10 LOA cases in cadaveric study
- All 3 clinical cases had uneventful recoveries post-IOA, including one carcinoma, with no intra- or short-term postoperative complications
- LOA had superior surgical exposure, but was more invasive and time-consuming
- IOA posed greater difficulty in complete gland removal in brachycephalic dogs, with remnant tissue noted in 2/10 cadavers
- IOA avoids osteotomy, reducing potential complications like delayed union and postoperative pain
- Cosmetic outcomes and healing were better with IOA, and no E-collar was required postoperatively

In Danielski 2022 et al., on humero-anconeal incongruity, what role did the novel caudo-medial arthroscope portal play in the study?
🔍 Key Findings
- A novel caudo-medial arthroscopic portal allowed visualization of previously undescribed cartilage lesions on the caudal medial humeral condyle.
- A consistent focal cartilage lesion (HA lesion) was observed in 100% of elbows with HIF (21/21), but in none of the 31 elbows without HIF.
- Lesions varied from indentations to full-thickness cartilage loss, typically elliptical and located just medial to the humeral condyle isthmus.
- A clunk-like sensation and dynamic engagement of the anconeal process into the lesion were observed in 16/21 elbows with HIF during elbow manipulation.
- In 5/21 elbows, engagement of the anconeal process led to observable widening of the HIF line, suggesting dynamic instability.
- Findings support a novel concept of humero-anconeal incongruity as a contributor to the pathogenesis of HIF.
- Spaniel breed was not a confounder—the lesion was only present in elbows with HIF, regardless of breed.
- The study suggests potential for using arthroscopy as a screening tool for early detection of humero-anconeal incongruity and HIF risk.

In Latifi 2024 et al., on fascial mapping in the canine hindlimb, which major nerve was highlighted as at risk during dissection in the medial thigh region?
🔍 Key Findings
- This anatomical study mapped fascial planes of the canine hindlimb and pelvis to aid superficial tumor resection.
- Type I fascia (discrete sheets) was suitable for deep margins in fascia lata, lateral crus, and gluteal regions.
- Areas with poor or absent fascia included the ischiorectal fossa, femoral triangle, stifle extensor mechanism, and pes.
- Type IV fascia associated with periosteum (e.g., patella, tibial tuberosity) required partial ostectomy for inclusion in surgical margins.
- Nerves at risk during deep dissection included obturator, superficial peroneal, and tibial nerves, particularly in regions with weak fascia.
- In males, bulbospongiosus muscle could act as a fascial plane but dissection was challenging and potentially hemorrhagic.
- In females, constrictor vulvae/vestibulae muscles were tightly associated with mucosa, limiting clean resection options.
- Distal hindlimb resections often lacked a usable fascial plane, suggesting that amputation or adjuvant therapy may be more appropriate.

In Buote 2023 et al., on 3D printed cannulas, how did the number of instrument collisions compare before and after 3DPC use?
🔍 Key Findings
- Customized 3D printed cannulas (3DPCs) significantly reduced surgical time in feline cadaver models (125.6 vs. 95.2 min, p = 0.03).
- Use of 3DPCs resulted in a reduction in instrument collisions (6.8 vs. 2.6, p = 0.03).
- Cannula pullout complications decreased with 3DPCs (10 vs. 2.2 per procedure, p = 0.03).
- 3DPCs were designed at shorter lengths (3 cm), improving intra-abdominal working space in cats.
- No incisional or postoperative complications occurred in the two live feline cases.
- One 3DPC insufflation port broke intraoperatively; resolved by using a male luer lock connector in the next case.
- CO₂ leakage occurred from re-used silicone valves in 2 ports; emphasizing the need for durable valve design.
- Estimated cost per 3DPC was <$5.00, suggesting cost-effective customization for feline laparoscopy.

In Philips 2025 et al., on radiographic IAIP detection, how did implants placed 2 mm into the joint perform in terms of accurate classification?
🔍 Key Findings
Overall accuracy of radiography to detect IAIP: 77.9%
Sensitivity: 97.2%
Specificity: 67.6%
False positive rate: 32.4% of non-penetrating implants were misclassified as penetrating
Implants directed toward the lateral tibial condyle had higher misclassification (23.8%) than medial (8.3%)
Most accurate detection: Implants placed 2 mm into the joint (97.2% correct classification)
Least agreement: For implants placed at 0 mm (subchondral level), especially lateral (AC1 = 0.48)
No palpable abnormalities (e.g., crepitus) observed during ROM for any group
No significant difference in detection by specialty field or reviewer qualification
Suggests radiographic misclassification risk and supports considering CT/fluoroscopy in equivocal cases

In Huerta 2025 et al., on leakage in canine lung lobectomy, what was the leakage pressure threshold exceeded by most total lobectomy (TL-30) stapled specimens?
🔍 Key Findings
PL-30 group (partial, TA30-V3 wedge):
- 100% leaked
- Median leakage pressure: 10 cm H₂O
- Most failures from periphery of staple line
PL-60 group (partial, TA60-3.5):
- 100% leaked
- Median leakage pressure: 18 cm H₂O
- Better than PL-30 (p = .006)
TL-30 group (total, TA30-V3):
- Only 1 of 11 leaked (at 22 cm H₂O)
- All others resisted pressures >50–65 cm H₂O
- Significantly higher leakage pressure than both PL groups (p < .001)
Odds ratios (leakage vs TL-30):
- PL-30: OR 437 at both 20 and 30 cm H₂O (p = .003)
- PL-60: OR 437 at 20 cm H₂O and 133 at 30 cm H₂O (p = .003)
Recommendation: Prefer TL-30 when possible. If partial needed, PL-60 superior to PL-30, but all partials leaked at physiologic pressures.

In Giansetto 2022 et al., on preputial urethrostomy, what complication was observed in 2 out of 4 dogs following the procedure?
🔍 Key Findings
- Modified preputial urethrostomy without penile amputation was successfully performed in 4 male dogs with urethral stenosis or trauma.
- The technique involved anastomosis of the pelvic urethra to the preputial mucosa via caudal celiotomy, avoiding perineal urethrostomy complications.
- No cases of skin scalding or stoma stenosis were reported during short- and long-term follow-up.
- Two dogs developed mild urinary incontinence, particularly when excited; one improved with phenylpropanolamine.
- The approach preserved local anatomy, avoiding penile amputation, osteotomies, and preputial dissection.
- Postoperative urinary catheterization was used to protect the anastomosis, although optimal duration remains debated.
- Surgical access via the linea alba minimized tension at the anastomosis site and avoided complications from paramedian approaches.
- This technique may serve as a viable alternative to prepubic urethrostomy, reducing urine-related skin complications and improving cosmetic outcome.
