In Scheuermann 2023 et al., on femoral MIPO alignment, what was a noted limitation of the prototype FRS?
🔍 Key Findings
- Precontoured plates using 3D-printed femoral models achieved near-anatomic alignment in all cadaver limbs.
- Fracture reduction system (FRS) required significantly fewer fluoroscopy images than intramedullary pin (IMP) methods (7 vs 26, P = .001).
- Despite longer surgical time (43 vs 29 minutes, P = .011), FRS showed equally accurate or better alignment compared to IMP.
- Femoral length, frontal, sagittal, and axial alignment were all within near-anatomic thresholds (<10 mm or <5° deviation) in both groups.
- FRS was associated with more consistent length maintenance, with IMP showing a median shortening of 2.3 mm (P = .03).
- Axial plane deviation was statistically different in the FRS group (P = .04), but still clinically acceptable.
- Study highlights potential for custom 3D-printed guides to reduce radiation exposure and improve precision in MIPO procedures.
- Authors caution that FRS was time-consuming and cumbersome, suggesting design refinements needed for clinical use.

In İnal 2025 et al., on feline high-rise trauma, which factor was most predictive of nonsurvival?
🔍 Key Findings
Sample: 373 cats with high-rise syndrome (HRS) from 2017–2020.
ATTS was the only significant predictor of survival (p < 0.001); each point increase decreased survival odds (OR = 0.46).
AUC for ATTS ROC curve: 0.857 (95% CI: 0.788–0.926).
Floor height, lesion type, and ground surface were not significantly associated with survival.
Odds of injury were 7.98× higher when landing on hard vs. soft surface (p < 0.001).
16.96× increased injury risk from the fourth vs. third floor (p = 0.008).
Cats with ATTS ≥7 had 62% mortality; median ATTS increased with floor height (r = 0.244, p < 0.001).
Thoracic and vertebral trauma were most common causes of death.
Only 32% of cats had the “classic” HRS triad (pneumothorax, epistaxis, hard palate fracture).

In Cheon 2025 et al., on guide accuracy in DFO, what was a notable advantage of the patient-specific guide?
🔍 Key Findings
- Both patient-specific and universal guides yielded correction errors <2°, with no statistically significant difference in accuracy.
- Universal guide corrected aLDFA up to 24° and AA up to 20°, addressing multiplanar deformities effectively.
- Patient-specific guides allowed for preoperative simulation, providing more stable pin placement and potentially aiding less-experienced surgeons.
- Universal guide eliminated the need for CT-based customization, reducing time and cost.
- Cadaver and bone model trials showed consistent accuracy, validating both methods in vitro and ex vivo.
- No significant differences in outcome when correcting uniplanar (aLDFA) vs biplanar (aLDFA + AA) deformities.
- Universal guide's fixed size presented limitations in small dogs, potentially requiring multiple size options.
- Universal guide showed potential for standard use, offering repeatable outcomes with minimal prep despite needing precise intraoperative placement.

In Danielski 2022 et al., on PAUL complications, what was the inter-observer agreement (kappa) for predicting complications from radiographs?
🔍 Key Findings
- Major complications occurred in 25.6% of limbs treated with PAUL, including non-union, implant failure, and infection requiring revision surgery.
- Increased body weight was significantly associated with a higher risk of complications (7% increased risk per additional kg; p = .04).
- Post-operative radiographic assessment was unreliable in predicting complications; inter-observer agreement was poor (kappa ≤ 0.12).
- Expert evaluation of implant or reduction errors had low predictive value (k < 0.2) for postoperative complications.
- Common major complications included non-union (6 limbs), screw breakage, and surgical site infections.
- Implant removal was required in 11.5% of limbs, mostly due to non-union or infection.
- Being a Labrador appeared protective on univariate analysis, but not on multivariate analysis after adjusting for weight.
- Radiographs showing suboptimal plate placement or osteotomy reduction did not reliably correlate with actual complication occurrence.

In Woelfel 2022 et al., on cervical locked facets, what was the most consistent outcome in dogs with follow-up?
🔍 Key Findings
- Locked facet injuries in dogs involved unilateral dorsal displacement of the cranial articular process of the caudal vertebra, most commonly at C5/6 or C6/7.
- All affected dogs were small/toy breeds, typically following trauma (most often attacks by larger dogs).
- Neurologic severity ranged from ambulatory tetraparesis to tetraplegia, often with thoracic limb deficits more severe than pelvic limbs — suggesting a central cord syndrome-like pattern.
- CT and MRI revealed axial rotation, subluxation, and articular process displacement; MRI showed T2 hyperintensity, nerve root impingement, and soft tissue changes.
- Surgical treatment included ventral fixation with screws, pins, and PMMA, and one case required dorsal facetectomy for reduction.
- Medical management, including external coaptation or rest, also resulted in functional recovery in select cases.
- All dogs with follow-up data (8/8) had functional recovery, with nonambulatory dogs regaining ambulation in a median of 4 weeks.
- No consistent differences in outcome were observed between surgical and nonsurgical management, suggesting locked facets may be biomechanically stable.

In Moore 2023 et al., on Divisional outcomes in canine liver mass resection, what was the effect of thoracic incision extension on postoperative complications?
🔍 Key Findings
- Liver masses were most common in the left division (58%), followed by central (27%) and right (15%).
- Right divisional masses were significantly associated with intraoperative complications (33% vs 5.6% left, p = .0037), particularly hemorrhage and injury to major vessels.
- Mortality rate was 6.5% overall, with no significant association with liver lobe location.
- Postoperative complications occurred in 28.7% of cases, but were not significantly associated with mass location.
- Thoracic incision extension (sternotomy or diaphragmotomy) increased odds of postoperative complications by 9.1x (p < .001).
- Use of TA stapler significantly reduced both intraoperative (OR 19x lower) and postoperative complications (OR 4.4x lower) vs other methods.
- Specialist surgeons and heavier dogs had significantly fewer postoperative complications.
- Right lobectomies often required thoracic extension, indirectly linking them to increased postoperative morbidity.
