- Aspiration pneumonia occurred in 1 dog immediately post-op and resolved with treatment
- Post-op esophagoscopy results varied, with persistent esophagitis in some cases
- Clinical response was variable, with ~25–30% of dogs being “non-responders” based on owner scoring
- 13/16 dogs showed partial or full clinical improvement, despite no change in objective SHH/GER indicators
- Final follow-up at median 36.5 months showed some dogs still on medical therapy; one underwent further surgery

In Clough 2022 et al., on CBLO-TTT construct testing, what is the clinical implication of combining CBLO and TTT?
🔍 Key Findings
- Combined CBLO-TTT did not reduce load to failure compared to CBLO or TTT alone (P = .81 and P = .12, respectively).
- CBLO-TTT maintains construct strength without significant compromise compared to individual procedures.
- Most common failure mode in CBLO-TTT was displacement of the tibial crest segment with k-wire pullout and tension band untwisting.
- No fulcrum effect was seen in CBLO-TTT, unlike TPLO-TTT combinations, likely due to preservation of buttress effect.
- Patellar ligament avulsion occurred in both CBLO and CBLO-TTT, but not as a clinical concern — possibly artifact from cadaver model.
- Load-to-failure testing was static and unidirectional, not accounting for cyclic fatigue or in vivo healing.
- Plate size and saw blade variation were based on clinical realism, introducing potential variability but not affecting outcomes.
- Study suggests feasibility of simultaneous surgical correction of CCL rupture and MPL using CBLO-TTT in dogs.

In Story 2024 et al., on surgical correction of excessive tibial plateau angle (eTPA), which procedure consistently under-corrected the tibial plateau angle despite a target TPA of 0°?
🔍 Key Findings
- All four techniques achieved TPA <14°, meeting the threshold for acceptable surgical correction in eTPA cases.
- Group A (CBLO + CCWO) and Group D (PTNWO) showed highest accuracy in achieving target TPA values.
- Group B (TPLO + CCWO) resulted in significant tibial shortening compared to other techniques.
- Group A caused the greatest cranial mechanical axis shift, while Group B caused the least.
- Group C (mCCWO) resulted in consistent under-correction of TPA, despite aiming for 0°.
- Modified or neutral wedge osteotomies (Groups C and D) had minimal effect on tibial length, making them suitable when preservation is important.
- All techniques involved mechanical axis shifts, highlighting the importance of preoperative planning to minimize morphologic disruption.
- Supplemental fixation was standard for all procedures to reduce risks such as tibial tuberosity fracture and plateau leveling loss.

In Jenkins 2022 et al., on medial epicondylar fissure fracture, what was the most significant risk factor for developing MEFF?
🔍 Key Findings
- MEFF occurred in 11.4% (10/88 elbows) following medial-to-lateral transcondylar screw placement in dogs with HIF.
- Screw size to condylar height ratio >41% significantly increased MEFF risk (P = .004, OR 1.52).
- MEFF was not recognized intraoperatively in 60% of cases and was only seen on follow-up or retrospective imaging review.
- Screw loosening was the most common complication (11.2%), observed both with and without MEFF.
- MEFF tended to increase the risk of screw loosening (P = .06), but was not statistically significant.
- Most MEFFs did not require treatment and healed radiographically by 14–17 weeks in monitored cases.
- Shaft screws were used in all MEFF cases, but shaft vs cortical design was not significantly associated with MEFF.
- The clinical impact of MEFF was minor in most cases, although long-term significance is unknown.

In Evers 2023 et al., on needle arthroscopy, what was a common limitation of needle arthroscopy compared to standard arthroscopy?
🔍 Key Findings
- Needle arthroscopy (NA) had 95% sensitivity and 100% specificity for detecting medial meniscal tears using standard arthroscopy (SA) as the reference.
- NA correctly identified meniscal status in 25/26 dogs, missing only one stable nondisplaced tear.
- NA took less time than SA: 8 ± 3 min vs. 15 ± 9 min (P = .0041).
- Visibility scores were significantly lower with NA than SA for all meniscal horns (medial and lateral) .
- Probing difficulty was greater with NA, especially for the lateral meniscus (P = .0017).
- NA caused no measurable morbidity: lameness scores were unchanged before and after the procedure (P = .25).
- NA was possible in sedated dogs, though 10/26 required additional anesthesia due to delays.
- NA missed 1 lateral tear, likely due to reduced access and lack of shaving compared to SA.

In Miller 2025 et al., on spinal drill guide accuracy, what was a reported technical benefit of the SOP plate when used with the 3D-printed guides?
🔍 Key Findings
- 3D-printed, SOP plate-specific guides enabled safe screw placement from T12–L5 in canine cadavers and models.
- All 140 screw trajectories were classified as Zdichavski Grade 1, indicating optimal placement without vertebral canal breach.
- Screw angles (cranial-caudal and transverse) matched preoperative planning, with no significant deviation.
- Entry/exit point deviations were <1 mm on average, deemed clinically negligible.
- Drill guides were quick to place (<30 sec per vertebra) and improved ease of surgery.
- Plates acted as effective reduction tools, guiding alignment during screw placement in mobile spines.
- Minor technical challenges arose from cadaveric spine mobility, mitigated by sequential screw insertion.
- Technique may enable future use in fracture/luxation reduction, pending further cadaveric and clinical trials.

In Thomsen 2024 et al., on CT accuracy for liver tumors, which anatomical level had the highest accuracy?
🔍 Key Findings
- CT localization of liver masses was more accurate by division (88%) than by lobe (74.3%)
- Inter-radiologist agreement was excellent for division (kappa up to 0.885) and only moderate–good for lobe
- Quadrate and right lateral lobes had significantly lower localization accuracy compared to left lateral or medial lobes
- CT localization of the left division was most accurate (90.1%) compared to central (77.1%) and right (88.3%)
- Portal and hepatic venous phases were equally helpful for localization (each ~30–38% usefulness)
- No significant associations found between histopathologic diagnosis and localization accuracy
- Lobe-level CT localization should be interpreted with caution, especially for the quadrate and right lateral lobes
- Radiologist experience likely influenced accuracy, with the most experienced radiologist performing best

In Stoneburner 2024 et al., on MIS survey results, what was the most commonly cited barrier to performing more MIS procedures?
🔍 Key Findings
- The survey included 111 practicing surgeons and 28 residents from ACVS, ECVS, and ANZCVS. 98.2% had performed soft tissue minimally invasive surgery (MIS).
- In the past year, surgeons reported a median caseload of 90% basic laparoscopy, 0% advanced laparoscopy, and 10% thoracoscopy; for residents: 100% basic laparoscopy, 0% advanced, 0% thoracoscopy.
- Laparoscopic ovariectomy and OHE were the most commonly performed MIS procedures, with most respondents proficient in basic laparoscopy, but few performing advanced laparoscopy or thoracoscopy.
- Top barriers to MIS adoption were: lack of consistent caseload, lack of training, difficult learning curve, equipment limitations, and cost.
- 76.6% of surgeons and 92.9% of residents received MIS training during residency. Those trained had completed residency median 6 years ago, compared to 22 years ago for those without MIS training (p < .001). Perceived adequate training correlated with higher proficiency.
- MIS was recognized as having a steep learning curve, but patient benefits (mean score 4.0/5) were the top motivation — less pain, faster recovery, improved visualization.
- The authors conclude basic laparoscopy is widely adopted, but advanced and thoracoscopic MIS remain underutilized. Training and access are key to future growth.
- Expanded training and improved access to equipment are necessary to promote broader integration of MIS into veterinary soft-tissue surgery.
