In Muroi 2025 et al., on refracture risk, what bone quality indicator was significantly lower in dogs that refractured **after plate removal**?
🔍 Key Findings
- Refracture occurred in 5.5% of limbs, with higher incidence in the plate removal group (12.5%) vs. non-removal (3.5%).
- In the non-plate removal group, refractures occurred at the most distal screw site, linked to greater screw position change during growth (OR 1.79, p=0.04).
- Screw-to-bone diameter ratio (SBDR) >0.4 was a significant risk factor for refracture in the plate retention group.
- In the plate removal group, refractures occurred at the original fracture site, associated with lower pixel value ratio (bone mineral density) and reduced radial thickness.
- Implant-induced osteoporosis (IIO) beneath the plate likely contributed to refracture risk after plate removal.
- Younger age at fracture (<6 months) was associated with higher refracture risk due to ongoing radial growth and shifting screw position.
- No significant association was found between refracture and plate type (locking vs conventional), fixation method, or ulnar union.
- Recommendations include careful SBDR sizing, motion restriction, and cautious plate removal decisions in growing dogs.

In Dobberstein 2022 et al., on NSAID ulcer repair, what clinical parameter was associated with a trend toward increased risk of death?
🔍 Key Findings
- Primary repair of NSAID-associated full-thickness gastroduodenal ulcers was successful in 73% (8/11) of cases.
- NSAID overdose, concurrent corticosteroid use, or extended duration were identified in 9/11 dogs and were major contributors to ulceration.
- All perforations were in the pylorus or proximal duodenum, locations suitable for primary closure.
- No significant association between ulcer size or location and postoperative survival.
- Preoperative hyperlactatemia trended toward increased mortality (P = .0544; OR 2.045).
- Postoperative vasopressor use was linked with a 9-fold increased risk of mortality (P = .0545).
- Dehiscence was rare, suspected in only 1 of 11 cases, indicating that primary repair is structurally sound in selected cases.
- Median follow-up of 444 days showed long-term survival was achievable post-primary repair.

- All failed RRCTs occurred in cats with perforations or tissue nonviability.
- Cats with failed RRCTs had longer clinical signs pre-surgery (median 6.5 vs. 2.0 days).
- Surgical time was longer in LFBO cats (median 77 min vs. 58 min, p = .0018).
- Preoperative septic peritonitis was rare (4/169 cats), but occurred only in linear or mixed FBO cases.

In Espinel Rupérez 2023 et al., on feline hip stabilization, what was the most frequent intraoperative complication during AA-HTS?
🔍 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.

In Deprey 2022 et al., on gap fracture implants, which material was the NAS-ILN made of?
🔍 Key Findings
- NAS-ILN had significantly greater stiffness in both axial compression and 4-point bending compared to LCP constructs.
- Ultimate load to failure was significantly higher for NAS-ILN in compression (804 N vs 328 N) and bending (25.7 Nm vs 16.3 Nm).
- Torsional stiffness and angular deformation were similar, but NAS-ILN resisted higher torque to failure than LCP (22.5 Nm vs 19.1 Nm).
- No slack was observed with the NAS-ILN construct, unlike older nail designs.
- Failure modes differed: LCPs failed via plate bending; NAS-ILNs failed at the implant or bone near screw holes.
- Titanium alloy and curved design of NAS-ILN provides better anatomic fit and more uniform stress distribution.
- A third, perpendicular locking hole in NAS-ILN may enhance torsional stability but was not utilized in this study.
- The curved, angle-stable design of NAS-ILN is a novel advancement in veterinary orthopedics.

In Kang 2022 et al., on 3D scaffold reconstruction, what was the histological status of the surgical margins after resection?
🔍 Key Findings
- Patient-specific 3D-printed PCL/β-TCP scaffold enabled successful zygomatic arch reconstruction in a dog.
- Complete surgical resection of a zygomatic parosteal osteosarcoma was achieved, with a 0.3 mm histologically clean margin.
- Post-op imaging showed progressive tissue ingrowth into the scaffold, with Hounsfield Units increasing from 20.4 to 97.8 over 10 months.
- No complications (e.g., infection, displacement) or tumor recurrence were noted at 16-month follow-up.
- Use of a patient-specific osteotomy guide improved anatomical fit and facilitated precise excision and implant placement.
- Facial symmetry and orbital stability were maintained throughout follow-up.
- The scaffold remained structurally stable despite limited bone regeneration, suggesting connective tissue filled the defect.
- Topical mitomycin C was applied intraoperatively for possible anti-neoplastic effect, but efficacy remains unclear.

In Longo 2022 et al., on CT-guided osteotomies, what was the primary method used to intraoperatively determine the amount of rotational correction needed for torsional deformities?
🔍 Key Findings
- 3D CT volume rendering and CAL measurement successfully guided correction of femoral and tibial torsion in dogs with patellar luxation (PL).
- Physiological patellar tracking was restored in 100% (22/22) of cases after detorsional osteotomy.
- 94% of dogs (17/18) had either full or acceptable functional outcomes post-surgery.
- CAL-based correction was accurate in 19/22 cases, confirming reliability of the measurement technique.
- Complication rate was 45%, with major complications in 2/22 cases—both involved combined femoral and tibial osteotomies.
- Combined femoral and tibial osteotomies in the same limb were linked to a higher risk of complications and poorer outcomes.
- Diaphyseal osteotomies offered more implant space, but metaphyseal locations were associated with faster bone healing.
- Use of a TPLO jig or goniometer was not essential—CAL-based bone marking was sufficient in most cases.
