In Jeon 2025 et al., on distal femoral shortening, what was the **median femoral shortening ratio** required to achieve prosthesis reduction?
🔍 Key Findings
- Distal femoral shortening osteotomy (DFSO) enabled prosthesis reduction in all 4 dogs with irreducible luxoid hips undergoing total hip replacement.
- Median femoral shortening ratio was 13.8% (range: 10.7–15.3%) based on intraoperative tension needed for prosthesis reduction.
- Bone union was achieved in all cases post-DFSO, indicating good healing potential.
- Two major complications occurred: one prosthetic luxation and one aseptic stem loosening requiring explantation.
- One intraoperative fracture of the greater trochanter occurred during trial reduction before DFSO.
- DFSO did not result in neurovascular injury, even in cases with significant femoral head displacement (>4 cm).
- Radiographic planning with FHD index and intraoperative assessment were crucial for determining DFSO necessity.
- DFSO avoids complications linked to subtrochanteric osteotomy by preserving proximal femoral anatomy and allowing secure distal fixation.

In Welker 2024 et al., on thoracic duct anastomosis with MAC device, what surgical consideration is recommended to improve outcomes?
🔍 Key Findings
- Anastomosis of the thoracic duct (TD) to the intercostal vein (ICV) using a microvascular anastomotic coupler (MAC) was feasible in all 6 healthy dogs
- Immediate postoperative patency was confirmed in all dogs, but only 4/6 had patent anastomoses at 30 days, with 2 failing due to ICV kinking
- Kinking of the ICV near the azygos vein insertion was the primary failure mechanism, likely from MAC malalignment
- No intraoperative or major postoperative complications occurred, though 2 dogs developed mild seromas
- Use of the MAC device simplified microsurgical anastomosis versus hand suturing, especially in the deep thoracic cavity
- Contrast lymphangiography showed faster clearance from the cisterna chyli postoperatively, suggesting effective flow redirection
- Persistent branches of the thoracic duct may impact outcomes, and should be ligated during surgery
- This technique may be a potential novel treatment for idiopathic chylothorax, improving outcomes by reducing collateral flow stimuli

In Miller 2024 et al., on intestinal obstruction and catheter technique in cats, what key factor was significantly associated with failed RRCT attempts?
🔍 Key Findings
- Cats with linear (LFBO) and discrete (DFBO) small intestinal obstructions had similar survival (98.2% vs. 97%, p = 1.0).
- Postoperative complications were not significantly different between LFBO and DFBO cases (p = .1386).
- Intestinal dehiscence was rare (only 2 cats), both in DFBOs, with no statistical difference between groups.
- Red rubber catheter technique (RRCT) successfully removed LFBOs in 83% (20/24) of attempts.
- 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 Danielski 2022 et al., on humero-anconeal incongruity, what arthroscopic finding was noted in all elbows with HIF but in none of the elbows without HIF?
🔍 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 Cheon 2025 et al., on guide accuracy in DFO, what correction capacities were designed into the universal 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 Dalton 2023 et al., In Minimally invasive acetabular fracture repair in dogs, what was the primary purpose of using mirrored 3D-printed hemipelves in this study?
🔍 Key Findings
- Feasibility study in 5 canine cadavers plus 1 clinical case (Chihuahua, 5.5 kg).
- Technique used two small approaches (caudal and craniolateral) connected with an epiperiosteal tunnel.
- Plates were precontoured on mirrored 3D-printed hemipelves to improve fit and reduce intraoperative bending.
- Cadaver outcomes: fracture gap <2 mm, step defect <1 mm, pelvic angulation <5°.
- Sciatic nerve injury was minimal: 1/5 cadavers had a mild indentation; others had no gross injury.
- Median total surgical time: ~46 minutes in cadavers; incisions ~5 cm.
- Clinical Chihuahua case: weight-bearing within 24 hrs, radiographic union at 3 months; one screw fractured but no adverse effect.
- Authors conclude: MIAF with 3D printing is feasible and accurate, but requires further evaluation before routine use.

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 Rocheleau 2025 et al., on infected total hip replacements, which pathogen was among the common isolates recovered?
🔍 Key Findings
Study Design: Case series of 8 dogs with confirmed or suspected PJI after total hip replacement (THR)
Dogs were categorized into:
- Curative intent (CI) group (n=5): short-duration infections, implant retention attempted
- Non-curative intent (NCI) group (n=3): chronic infections, implants scheduled for removal or revision
Success Rate: 7 of 8 dogs had infection resolution, including 4 of 5 in the CI group
Sampling sensitivity:
- Arthroscopic culture success was 80% in the CI group but only 33% in the NCI group
- All explanted implants from NCI group yielded positive cultures
Common isolates: Staphylococcus pseudointermedius (including MRSP), S. epidermidis, Stenotrophomonas maltophilia, and E. coli
Ancillary treatments included:
- Partial synovectomy, high-volume lavage (5–10 L), biofilm-depleting lavage, and/or amikacin-impregnated calcium sulfate beads
Mean follow-up: >1 year (mean 812 days); no signs of recurrence in successfully treated cases
Conclusions: Arthroscopic management of THR infections is feasible and effective in appropriately selected dogs. Success aligns with human literature when infection type is favorable (Type 1, 3, 4). Sensitivity of arthroscopic culture is higher in early/acute infections.

In Knudsen 2024 et al., on CTA diagnosis, what was the approximate percentage of menisci correctly classified in second readings?
🔍 Key Findings
- Multidetector CTA had high sensitivity (up to 100%) and specificity (up to 96%) for detecting medial meniscal tears in dogs.
- Observer experience significantly influenced diagnostic accuracy, with more experienced observers showing higher agreement and better performance.
- Training effect was evident, as less experienced observers improved between first and second readings.
- Positive likelihood ratios ≥4.6 and negative likelihood ratios ≤0.08 were observed, suggesting CTA is clinically useful for confirming or ruling out meniscal injury.
- CTA allowed identification of full and partial thickness lesions, with good visualization in sagittal, transverse, and frontal reconstructions.
- Approximately 90% of menisci were correctly classified in second readings.
- No adverse reactions were noted from the contrast injection; sedation was used instead of general anesthesia.
- CTA was less invasive and potentially more cost-effective compared to arthroscopy, especially in settings without MRI access.
