In Tobias 2022 et al., on perineal hernia repair positioning, what was the recurrence rate in dogs with prior hernia repair on the same side?
🔍 Key Findings
- Perineal hernia repair was feasible in dorsal recumbency in all 23 dogs, allowing simultaneous perineal and abdominal procedures without repositioning.
- Internal obturator muscle transposition (IOMT) was successfully performed in 22 dogs, with tendon transection facilitating improved muscle elevation.
- Complication rate was 60.9% in-hospital and 47.8% post-discharge, mostly minor (e.g., swelling, drainage), with infection suspected in 4 dogs (17.4%).
- Recurrence rate was 19% overall, but significantly higher in dogs with prior hernia repairs (50% vs 5.9%; p = 0.053).
- Dogs without prior repairs or organ pexies had no recurrences (p = 0.035), suggesting primary repairs without preexisting interventions fare better.
- Castration and adjunctive abdominal procedures (e.g., colopexy, cystopexy) were often performed concurrently (18/23 dogs).
- Colopexy did not prevent recurrence, although it aided in surgical visualization during perineal repair.
- Dorsal positioning allowed simultaneous access to the abdomen and perineum, improving surgical efficiency without added complications.

In Miller 2024 et al., on surgical comparison of staphylectomy vs. FFP, which outcome was significantly associated with folded flap palatoplasty?
🔍 Key Findings
- FFP resulted in longer median surgery (75 min) and anesthesia (111 min) durations than S (51 min and 80 min, respectively).
- No significant difference in anesthetic complications, regurgitation, aspiration pneumonia, or hospitalization time between S and FFP.
- Major complications were rare (4%) and equally distributed between procedures; included tracheostomy and euthanasia due to severe airway disease.
- Postoperative oxygen use was common (52% of dogs) but not significantly different between procedures.
- FFP dogs more often had laryngeal collapse (especially Grade 1: 68% vs. 32% in S dogs).
- Most dogs (85%) had concurrent nares surgery, with caudal wedge resection more frequent in FFP dogs.
- Few dogs needed revision soft palate surgery (7/124 total); similar between groups.
- Postoperative clinical signs improved across both procedures; regurgitation was the most persistent sign post-op.

In Mazdarani 2022 et al., on CBLO and stifle biomechanics, which statement best describes the **patellar ligament angle (PTA)** after CBLO?
🔍 Key Findings
- CBLO reduced tibial plateau angle (TPA) from a mean of 28.1° to 9.7°, aligning with its goal of flattening the tibial slope.
- CBLO eliminated cranial tibial translation (CTT) following CCL transection and meniscal release at all angles except 140° without hamstring load.
- Hamstring loading (20% quadriceps load) significantly reduced or delayed the onset of CTT, improving stifle stability.
- Medial meniscus was confirmed as a secondary stabilizer; its release (MMR) caused more CTT than CCLx alone.
- PTA (patellar tendon angle) increased with joint extension; CBLO shifted the PTA curve lower and parallel to intact values, suggesting effective flexion of the joint.
- Combined CBLO and hamstring loading resulted in the most stable joints, especially from 50° to 135° joint angles.
- Residual CTT occurred in CBLO-only limbs at higher extension angles (e.g., 140°), but hamstring load mitigated this.
- Stifle stability post-CBLO is multifactorial, depending on joint angle, meniscal integrity, and hamstring activation.

In De Moya 2023 et al., on femoral pinning outcomes, what was a reported benefit of FGPP over open techniques?
🔍 Key Findings
- FGPP (fluoroscopic-guided percutaneous pinning) resulted in successful healing in 10/13 fractures, with good limb function.
- Complications occurred in 5 of 11 cases, including intra-articular implants, malunion, implant failure/nonunion, and implant migration.
- Cases with delayed surgery (>15 days) or radiographic remodeling were more likely to experience major complications.
- Most fractures (10/13) were classified as Salter-Harris type I with mild displacement.
- Median surgical time was 60 minutes, and no conversions to open surgery were needed.
- Postoperative femoral neck resorption was minimal, suggesting possible benefits of the minimally invasive approach for preserving vascular supply.
- One intra-articular pin led to progressive joint disease and required femoral head ostectomy.
- FGPP appears best suited for acute, minimally displaced fractures in young dogs (<8 months) with planned elective explant to avoid growth disturbance.

In Dobberstein 2024 et al., on liver biopsy forceps, how did the number of portal triads compare between forceps sizes?
🔍 Key Findings Summary
- Subjects: 12 healthy colony cats, 68 total liver samples collected via laparoscopy
- Biopsy instruments: 3 mm vs 5 mm Storz Blakesley cup forceps
- Techniques: Twist (T), Pull (P), Twist + Pull (TP)
- Results:
- 5 mm forceps yielded significantly more hepatic lobules (mean 12.4 vs 4.9), portal triads (29.6 vs 19.0), weight, and histologic area (p < .01)
- T and P techniques yielded more portal triads and lobules than TP (p = .003 and p = .015)
- TP technique resulted in greater tissue crush vs T (p = .01)
- Good diagnostic agreement between 3 mm and 5 mm samples only with TP (κ = 0.75)
- All samples were of sufficient diagnostic quality, despite size or technique
- Clinical implication: Both 3 mm and 5 mm forceps are viable; further studies are needed to confirm diagnostic accuracy of 3 mm samples

In Canever 2022 et al., on labial flap vascular anatomy, which factor is considered most critical for survival of labial musculomucosal axial flaps?
🔍 Key Findings
- Superior and inferior labial arteries in cats perfuse robust angiosomes, which support musculomucosal axial pattern flaps.
- Cadaver angiography confirmed vascular anatomy, with consistent patterns between sides and among specimens.
- The vascular supply is located primarily in the musculomucosal layer, not the skin, critical for flap viability.
- Flap harvest requires inclusion of the orbicularis oris (± buccinator) muscle to ensure vascular integrity and flap survival.
- Two clinical cases demonstrated successful use of superior and inferior labial musculomucosal flaps for palatal reconstruction with complete flap survival and resolution of clinical signs.
- Intraoperative transillumination aided vessel localization, facilitating surgical planning and flap design.
- No cases of distal flap necrosis or dehiscence occurred, although mild donor site morbidity (lip retraction, mucosal denuding) was noted.
- These flaps offer a valuable option when local tissues are compromised, especially after failed previous repairs or radiation therapy.

In Danielski 2022 et al., on humero-anconeal incongruity, what dynamic sign was frequently observed during elbow manipulation in dogs with 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 Butare-Smith 2022 et al., on cerclage knot biomechanics, which cerclage knot had the **highest initial tension** before testing?
🔍 Key Findings
- Double-loop cerclage resisted the highest peak load (805 N) and maintained tension longer than twist (488 N) and single-loop (397 N) configurations.
- Double-loop cerclage sustained 500,000 cycles at 60–80% of peak load in some cases without loosening, outperforming other types.
- Twist knots loosened rapidly, often within 10 cycles even at low loads (100–390 N).
- Single-loop knots performed better than twist, with partial resistance up to 100,000 cycles at 160 N, but showed wide variability.
- All loosening occurred before wire breakage, indicating clinical failure would happen from slack, not fracture.
- Double-loop cerclage had highest initial tension (323 N) compared to single-loop (124 N) and twist (69 N).
- Fatigue limit was not identified for twist, since they all loosened early at even 20% of peak load.
- Clinical recommendation: double-loop cerclage is best for resisting repeated subfailure loading, ideal for fissure prevention or fragment stabilization.

In Dobberstein 2022 et al., on NSAID ulcer repair, what was a common factor among most dogs that developed gastrointestinal perforations?
🔍 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.
