In Carwardine 2024 et al., on screw placement in HIF, which placement direction was associated with a significantly higher complication rate?
🔍 Key Findings
- 73 elbows (52 dogs) underwent randomized medial or lateral transcondylar screw placement for HIF.
- Lateral-to-medial placement resulted in a significantly higher rate of complications (62.2%) vs medial-to-lateral (19.4%) (p = .001).
- Odds ratio for complications: 6.11 (95% CI: 2.13–17.52).
- Most common complications: seromas (n = 13), surgical site infections (n = 16).
- Implants with lower AMI/bodyweight were significantly associated with major complications (p = .037).
- Only 4 procedures (5%) required revision surgery (major type I complications), with no difference by screw direction.
- NNT = 2.3 for medial placement to prevent one complication.

In Scheuermann 2024 et al., on 3D-printed reduction systems, how did the complication rates compare between groups?
🔍 Key Findings
- The study was a historic case-control trial comparing custom 3D-printed VSP-guided MIPO (3D-MIPO) to conventional MIPO (c-MIPO) in dogs with diaphyseal tibial fractures.
- Surgical time was significantly shorter in the 3D-MIPO group (117 min vs. 151 min; p = .014), and fluoroscopy use was dramatically reduced (11 vs. 37 images; p < .001).
- All 3D-MIPO reductions were acceptable or near-anatomic; 2 c-MIPO dogs had unacceptable reductions.
- Tibial length, frontal, and sagittal alignment post-op were similar between groups; no significant difference in anatomic restoration (p > .1).
- Radiographic union occurred in all dogs by 3 months. Time to union was similar between groups (3D-MIPO: 67 days vs. c-MIPO: 53 days; p = .207).
- Postoperative complication rate was higher in 3D-MIPO (27% vs. 14%), including 2 major infections requiring implant removal.
- 3D-MIPO required more pre-op time (~23 hours longer from presentation to surgery; p = .002), partly due to guide printing/sterilization.
- Improved surgical efficiency and more consistent reductions were noted in the 3D-MIPO group, supporting its clinical utility despite increased pre-op logistics.

🔍 Key Findings
- Hepatic venous drainage patterns vary widely across all lobes, especially the left lateral lobe.
- Right lateral lobe had a median of 2 vessels draining directly into the caudal vena cava (CVC); range: 1–4.
- Caudate process of caudate lobe had the most variability: 1–5 vessels draining into the CVC; 2 vessels was most common (54.5%).
- Left lateral lobe drained via 2–8 veins into the left hepatic vein (LHV), with 3 veins most common (31.2%).
- Left medial lobe typically had 1 vein draining into the LHV (61% of dogs).
- Papillary process drained into the LHV in 93.5% of cases; 6.5% drained directly to the CVC.
- Quadrate lobe always had 1 vessel draining either directly to the CVC or via the LHV.
- CTA revealed more variations than previously described in plastinated or cadaveric studies, highlighting its superior value in surgical planning.

In Espinel Rupérez 2023 et al., on feline hip stabilization, what was the most common type of iatrogenic injury observed in cadaveric joints?
🔍 Key Findings
- Arthroscopic-assisted hip toggle stabilization (AA-HTS) was successfully completed in all 14 feline cadaver joints.
- Femoral and acetabular tunnel creation was feasible in all cases, though femoral tunnel placement had a higher rate of deviations.
- Intraoperative complications occurred in 5/14 joints, mostly related to femoral tunnel creation and toggle lodging.
- Minor articular cartilage injury (<10% total cartilage area) occurred in 10/14 joints, but no injury to neurovascular or intrapelvic structures.
- Thirteen surgical technique deviations (8 major, 5 minor) were identified in 7 joints, all involving the femoral tunnel.
- Toggle passage through the femoral tunnel was the most challenging step, being mildly difficult in 6 joints.
- Postoperative CT and gross dissection confirmed all toggles and buttons were in correct position, without damage to major surrounding structures.
- No deviations, complications, or cartilage injuries occurred in the last 4 joints, suggesting a learning curve effect.

In Lomas 2025 et al., on DPO and dorsolateral subluxation, which of the following factors had **no significant impact** on change in DLS score after DPO?
🔍 Key Findings
- DPO significantly improved femoral head coverage, increasing mean DLS from 36.1% to 71.4% postoperatively (p < 0.001).
- No significant change in DLS between immediate postoperative and follow-up scans, suggesting stable surgical outcomes over time.
- Greater plate angle (30°) yielded larger DLS improvement (mean increase: 39.8%) compared to 25° and 20° plates.
- Only 3 hips had post-op DLS scores <55%, indicating most patients had lower risk of osteoarthritis progression.
- No correlation found between DLS improvement and age, body weight, or side of surgery, suggesting broad applicability.
- CT was used for DLS measurement in simulated weight-bearing, improving precision over radiographic methods.
- Major limitations included small sample size, multiple surgeons, and variable sedation vs anesthesia during imaging.
- DPO confirmed as effective for reducing dorsolateral subluxation, improving coxofemoral joint congruency in dysplastic dogs.

In Miraldo 2026 et al., on TPLO plate compression, what method was used to measure interfragmentary compression at the osteotomy interface?
🔍 Key Findings
- Biocurve TPLO plate generated the highest and most uniform interfragmentary compression, particularly in the cranial quadrants (Q1: 0.285 MPa; Q2: 0.304 MPa), due to its opposing angled dynamic compression holes.
- Synthes TPLO plate produced the lowest compression across all quadrants (0.050–0.111 MPa), remaining within the low compression range.
- Arthrex plate achieved intermediate compression, with high compression in the craniolateral quadrant (Q2: 0.292 MPa) but only moderate compression elsewhere.
- Plate design significantly affected compression distribution (p < 0.001), confirming that screw hole orientation and plate geometry influence osteotomy compression patterns.
- Cranial compression (Q1–Q2) was greatest with the Biocurve plate, potentially improving stability against “rock-back” or loss of tibial plateau angle.
- No significant differences between plates were found in caudal quadrants (Q3–Q4), suggesting plate design primarily affects cranial compression.
- Pressure-sensitive film analysis allowed quantitative mapping of compression patterns, dividing the osteotomy interface into four quadrants for standardized comparison.
- Clinical superiority of one plate was not concluded, but findings suggest plate geometry and dynamic compression hole orientation influence mechanical stability during TPLO fixation.

In Downey 2023 et al., on thoracoscopic lung lobectomy, what technical challenge was more frequently encountered in brachycephalic dogs during OLV?
🔍 Key Findings
- Thoracoscopic (TL) and thoracoscopic-assisted (TAL) lobectomy were performed in 12 dogs with non-neoplastic pulmonary consolidation.
- 44% (4/9) of TL cases required conversion, most often due to pleural adhesions or poor visualization — a higher rate than for neoplastic lobectomies.
- Surgical mortality was 8.3% (1/12 dogs), with death attributed to unaddressed BOAS, not surgical complications.
- All 11 surviving dogs had no recurrence of clinical signs at a median 24-month follow-up.
- Perioperative complications occurred in 58% (7/12): pneumothorax (2), hemorrhage (3), wound dehiscence (1), progressive pneumonia (1).
- One-lung ventilation (OLV) was successful in 78% of TL dogs but may be harder to achieve in brachycephalic breeds.
- Most dogs had infectious pneumonia (10/12), with bacterial causes identified in 8; fungal and viral etiologies were less common.
- Hospitalization was short, with median stays of 3–4 days depending on approach and conversion status.

🔍 Key Findings
- Barbed sutures showed comparable leakage pressure to traditional sutures and stapling devices (p = .36).
- No bronchial leaks occurred at physiological pressure (<20 cmH₂O) in any group.
- Leakage at supraphysiologic pressure (20–80 cmH₂O) occurred in 90% of stapler, 80% of traditional, and 60% of barbed suture closures.
- Barbed sutures reduced ligation time significantly compared to traditional sutures (10.7 vs. 14.1 minutes, p < .01).
- Staplers remained fastest, with mean ligation time of 2.4 minutes.
- No knot failure or suture breakage was observed in barbed or traditional suture groups.
- Leakage in barbed sutures occurred mostly at the loop effector zone, but remained within acceptable limits.
- Barbed sutures may offer an effective alternative when staplers are unavailable, impractical, or cost-prohibitive.
