In Shetler 2022 et al., on radial head OCD, what was the main advantage of the lateral arthroscopic approach over the standard medial approach?
🔍 Key Findings
- Bilateral radial head OCD lesions were identified in a 6-month-old English Bulldog with elbow lameness.
- Medial arthroscopic portals allowed only partial visualization of radial head lesions, insufficient for treatment.
- Lateral arthroscopy portals provided excellent access for fragment removal and abrasion arthroplasty.
- Histopathology confirmed OCD, showing cartilage degeneration and retained cartilaginous cores.
- Dog showed complete resolution of lameness and no elbow pain at 5 months post-op.
- Lesions were caudolateral on the radial head, with discoid elevation of cartilage and clefts.
- Lateral approach avoids major neurovascular structures, reducing iatrogenic risk.
- The authors suggest lateral elbow arthroscopy may have broader indications, including for medial compartment disease or synovial biopsies.

In Latifi 2022 et al., on forelimb fascial mapping, what surgical strategy may be required for wide tumor excision over the triceps tendon region?
🔍 Key Findings
- Fascia was present over most of the canine forelimb, but key areas like the elbow, carpus, and manus lacked robust fascial planes for wide resection.
- Type I fascia (discrete sheet) was primarily found in the antebrachium, with type IV (periosteal) fascia located at the olecranon, scapular spine, and accessory carpal bone.
- Distal antebrachial fascia was thin and adherent, often blending with carpal structures and lacking reliable surgical planes.
- Partial tenectomy or joint capsule resection was often required for wide excision in the distal limb, especially over the triceps tendon and carpus.
- Nerve transections (e.g., superficial radial or ulnar branches) were commonly needed to maintain fascial margins, though often with minimal functional loss due to overlapping innervation.
- Digital and metacarpal pads lacked clear deep fascial borders, making digit amputation necessary for oncologic margins in distal tumors.
- Dissections revealed fascial junctions as either Type A (easily separable) or Type B (risk of disruption), guiding resection plane selection.
- Findings provide a surgical map to guide preoperative planning for superficial tumor excision on the forelimb.

In Sherman 2023 et al., on minimally invasive ESF, what was the effect of intraoperative imaging on alignment?
🔍 Key Findings
- 55 cases (49 dogs, 6 cats) with nonarticular tibial fractures were treated using linear ESF with a minimally invasive approach
- All fractures achieved radiographic union; no unacceptable outcomes were reported
- 40% complication rate, mostly minor (82%), primarily pin-tract morbidity; major complications (7%) included osteomyelitis and refracture
- Open fractures had significantly more major complications than closed ones (P = .019)
- Use of intraoperative imaging (72% cases) reduced surgery time but did not improve alignment (P > .05)
- Median surgery time: 74 min with imaging vs. 100 min without (P = .046)
- TPA was lower than normal in both dogs and cats, but did not correlate with poor outcomes
- 62% had full clinical recovery, and 38% had acceptable outcomes at fixator removal

In Lampart 2023 et al., on manual laxity testing, how did subjective estimates of cranial tibial translation (CTT) compare with objective values?
🔍 Key Findings
- Cranial drawer (CD), tibial compression (TCT), and tibial pivot compression test (TPCT) showed 100% sensitivity and specificity in differentiating intact from CCL-deficient stifles in this ex vivo model.
- TPCT elicited the highest cranial tibial translation (CTT) and internal tibial rotation, though differences in rotation did not reach statistical significance.
- Inter- and intraobserver agreement for CTT was excellent across all tests (ICC >0.9).
- Rotation and force application had greater variability, particularly with less experienced observers and during CD.
- Forces applied during CD were significantly higher in intact limbs and correlated with observer experience.
- Subjective CTT estimates strongly correlated with objective kinematic measurements (r = 0.895), with a median absolute error of 1.31 mm.
- TPCT may be particularly useful for assessing rotational instability, mimicking the pivot-shift test used in human ACL exams.
- Study supports development of a grading system for manual laxity testing, especially in acute CCLR cases.

In McCagherty 2025 et al., on WID detection accuracy, how did image-guided swabs compare to non-guided swabs in bacterial yield?
🔍 Key Findings
- Bacterial fluorescence was detected in all wounds (17 dogs, 4 cats) using the point-of-care wound imaging device (WID).
- The WID confirmed the presence of clinically relevant wound infection in all evaluated cases at the time of imaging.
- No significant difference was found in bacterial yield or burden between image-guided and non-guided swabs (QBC and PCR; p > 0.05).
- The WID helped guide wound debridement in some cases by localizing areas of fluorescence, especially in necrotic tissue.
- Most infections were polymicrobial and dominated by anaerobes, highlighting the need for anaerobic culture inclusion.
- PCR analysis showed low bacterial DNA yields, often complicated by host DNA contamination, limiting its utility.
- The study did not evaluate sensitivity/specificity of WID, as only fluorescence-positive wounds were included.
- Clinical utility of WID lies in immediate visual confirmation of infection, supporting timely antimicrobial treatment decisions.

In Mayhew 2023 et al., on BOAS surgery effects, what percentage of dogs were considered “non-responders” based on owner scoring?
🔍 Key Findings
- Owner-reported regurgitation improved after CMS, especially post-eating and during activity (P = .012 and P = .002)
- No significant improvement in VFSS measures of SHH or GER postoperatively (P > .05 for all comparisons)
- Laryngeal ventriculectomy and soft palate resection were performed in all dogs, alaplasty in 14/16
- 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 Monnet 2023 et al., on barbed vs conventional suture in vesicourethral anastomosis (VUA), what was the key finding regarding leakage pressure?
🔍 Key Findings
- Leakage pressure was not significantly different between unidirectional barbed suture (UBS) and conventional (C) suture groups (p = .236).
- UBS group had a 28% lower median leakage pressure than the C group (8.6 mmHg vs. 11.7 mmHg), suggesting higher biological risk of leakage.
- UBS significantly reduced suturing time (median 12.7 vs. 17.3 minutes; p < .0002).
- Fewer suture bites were needed in the UBS group (median 14 vs. 19; p = .012).
- No suture breakage or urethral narrowing occurred in either group.
- Leakage site distribution (ventral vs lateral) was similar between groups; no dorsal leaks noted.
- Leakage occurred as low as 5 mmHg in UBS group, indicating potential for postoperative extravasation.
- UBS may aid intracorporeal suturing in minimally invasive prostatectomy, but catheterization remains necessary postoperatively.

In Clough 2022 et al., on CBLO-TTT construct testing, what key limitation affects clinical translation of this study?
🔍 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 Ramsey 2025 et al., on tibial alignment, what effect did bent interlocking nails have on medullary canal fill?
🔍 Key Findings
- Straight interlocking nails (sILN) resulted in a significantly higher postoperative TPA compared with the contralateral limb (+5°), whereas bent nails (bILN) increased TPA by only +1°.
- Bent interlocking nails achieved closer-to-anatomic tibial plateau alignment than straight nails (p < .0001).
- Both techniques resulted in mild valgus malalignment (~2°) compared with the contralateral limb, but this was not clinically significant.
- No significant differences in medial mechanical proximal tibial angle (mMPTA) were detected between groups.
- Medullary canal fill was higher with bent nails (by ~6.6%), suggesting improved coaxial nail placement.
- Missed bolt hole frequency did not differ between straight and bent nail techniques.
- Complication rates were very low, with only one clinically relevant malalignment reported in the bent nail group.
- Despite higher TPA in the straight nail group, no increased incidence of CCL rupture was identified during follow-up.

In Perez Neto 2025 et al., on hip resurfacing arthroplasty, what was the impact of implant positioning (neutral vs valgus) on biomechanical performance?
🔍 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.
