In Low 2025 et al., on machine-learning outcomes in IVDE, which factor was associated with improved functional recovery?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Fenestration was among the top predictive features associated with better recovery.
Incorrect. The correct answer is Fenestration performed.
Fenestration was among the top predictive features associated with better recovery.

🔍 Key Findings

The study included 162 deep-pain-negative dogs undergoing decompressive surgery (hemilaminectomy) for acute thoracolumbar intervertebral disc extrusion (IVDE).

Ambulatory recovery occurred in 53.1% of dogs (86/162).

The best performing machine-learning model was XGBoost, with an AUC of 0.9502 and accuracy of 89.1%, outperforming Ridge, AdaBoost, and Naive Bayes models.

Preoperative-only XGBoost models were less accurate, with AUC dropping to 0.8271 and accuracy to 71.9%.

Top predictive features (by SHAP analysis) included:

  1. T2-weighted to L2 spinal cord signal ratio (lower values predicted better outcome)
  2. Use of fenestration (presence associated with better recovery)
  3. Hospitalization duration
  4. Imaging modality used
  5. Duration of nonambulatory status

Machine learning provided better insight into prognostic factors than traditional statistical methods.

In Gollnick 2024 et al., on TCTF risk with Arthrex STS in TPLO, which factor most contributed to serious tibial fracture following TCTF?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Both major complications were associated with angulated cortical screws in the distal plate holes.
Incorrect. The correct answer is Angled cortical screw in distal hole.
Both major complications were associated with angulated cortical screws in the distal plate holes.

🔍 Key Findings

  • 42% of dogs (33/78) treated with Arthrex 3.5 mm STS during TPLO developed radiographic TCTF
  • TCTFs occurred exclusively distal to the osteotomy
  • 14% of screws (36/250) distal to the osteotomy were associated with TCTFs
  • 6% of dogs with TCTFs developed major complications (e.g., complete tibial fracture requiring surgical revision)
  • Angulation of cortical STS screws, especially in the distal plate holes, was a key contributor to complications
  • Locking screws were also involved, but cortical screws angled improperly were overrepresented in serious outcomes
  • Revision recommendations included preemptive fixation for large TCTFs or angulated screw placements
  • Use of non-self-tapping screws (NSTS) previously showed a <1% TCTF rate, supporting higher risk with STS

In Davies 2024 et al., on lymphaticovenous anastomosis, what intervention resolved partial occlusion of the thoracic duct after MAC coupling in one cat?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Twisting of the TD was corrected by anchoring it with a tacking suture.
Incorrect. The correct answer is Tacking suture between TD and thoracic wall.
Twisting of the TD was corrected by anchoring it with a tacking suture.

🔍 Key Findings

  • Lymphaticovenous anastomosis (TD to AV) was successfully performed in all 8 feline cadavers using a microvascular anastomotic coupler (MAC).
  • Anastomotic patency was confirmed intraoperatively and postoperatively in 7/8 cats via contrast lymphography or retrograde venography.
  • Dissection and anastomosis took a median of 120 minutes, with minimal technical complications.
  • A 1.5 mm MAC was used in 6 cats, and a 2.0 mm in 2 cats; TD diameter ranged 1.0–1.5 mm, AV up to 2.25 mm.
  • Challenges included vessel twisting and luminal patency issues, resolved intraoperatively with minor adjustments (e.g., repeat pinning, tacking suture).
  • MAC use eliminated need for hand-suturing, lowering skill demands but requiring precise alignment.
  • Technique provides direct lymphatic-to-venous drainage, potentially reducing the stimulus for collateral vessel formation.
  • May serve as a future treatment option for feline idiopathic chylothorax, warranting further in vivo studies.

In Scheuermann 2024 et al., on 3D-printed reduction systems, what percentage of dogs in the 3D-MIPO group had near-anatomic or acceptable fracture reductions?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. All fractures in the 3D-MIPO group had near-anatomic or acceptable reduction, whereas the c-MIPO group had two unacceptable reductions.
Incorrect. The correct answer is 100%.
All fractures in the 3D-MIPO group had near-anatomic or acceptable reduction, whereas the c-MIPO group had two unacceptable reductions.

🔍 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.

In Hoenecke 2025 et al., on radiographic opacity in patella luxation, what percentage of dogs with long-term follow-up developed subsequent CCL rupture?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. 4 of 21 dogs (19%) with long-term follow-up developed a CCL rupture after patella luxation surgery.
Incorrect. The correct answer is 19%.
4 of 21 dogs (19%) with long-term follow-up developed a CCL rupture after patella luxation surgery.

🔍 Key Findings

  • 65% of stifles with patella luxation and intact CCLs had increased radiographic soft tissue opacity
  • Weight and radiographic OA were significantly associated with increased opacity (p = .0029 and p = .0143)
  • Each 1 kg increase in weight increased the odds of opacity by 10%
  • Grade of patella luxation, age, and muscle atrophy were not significantly associated with increased opacity
  • 19% of dogs with long-term follow-up developed a CCL rupture post-patella surgery, 50% of those had opacity at initial presentation
  • Radiographic opacity alone should not be interpreted as CCL disease in dogs with patella luxation
  • Radiographic findings likely represent effusion or synovial hyperplasia, not CCL pathology
  • Arthrotomy was used to confirm CCL integrity at surgery, but arthroscopy could provide better sensitivity

In Mazdarani 2022 et al., on CBLO and stifle biomechanics, what was the **mean postoperative tibial plateau angle (TPA)** achieved after CORA-based leveling osteotomy (CBLO)?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. CBLO reduced the mean TPA from 28.1° to 9.7°, consistent with the surgical goal of flattening the tibial slope.
Incorrect. The correct answer is 9.7°.
CBLO reduced the mean TPA from 28.1° to 9.7°, consistent with the surgical goal of flattening the tibial slope.

🔍 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 physeal/neck fracture repair, which factor was most associated with the development of complications following FGPP?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Cases with >15 days between injury and surgery showed remodeling and had a higher complication rate.
Incorrect. The correct answer is Fracture chronicity >15 days.
Cases with >15 days between injury and surgery showed remodeling and had a higher complication rate.

🔍 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 Azuma 2024 et al., on 3D vs 2D laparoscopy, how did the total surgical times compare between 2D and 3D laparoscopic groups?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Although 3D improved one procedural step, the overall surgical time did not differ between groups.
Incorrect. The correct answer is No significant difference.
Although 3D improved one procedural step, the overall surgical time did not differ between groups.

🔍 Key Findings

  • 3D laparoscopy significantly reduced time to first endoclip placement compared to 2D (median 76 vs. 238 seconds, p = .016).
  • Total surgical time was not significantly different between 3D and 2D groups.
  • No differences were observed in intraoperative complications such as cystic duct injury, clip dislodgment, or gallbladder perforation.
  • Cystic duct stump length was comparable between groups (median 2.5 mm).
  • Liver parenchyma attachment severity did not differ significantly between 2D and 3D groups.
  • All procedures were performed by an experienced surgeon, potentially reducing the benefit seen with 3D visualization.
  • No conversions to open surgery occurred, and no intraoperative complications were reported.
  • The study suggests 3D laparoscopy may aid less experienced surgeons due to enhanced depth perception.

In Hertel 2025 et al., on portal venotomy for insulinoma, which postoperative complication was observed and medically managed?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Moderate pancreatitis was the only notable postoperative complication and was managed conservatively.
Incorrect. The correct answer is Pancreatitis.
Moderate pancreatitis was the only notable postoperative complication and was managed conservatively.

🔍 Key Findings

  • Portal venotomy enabled successful en bloc resection of a pancreatic insulinoma and associated thrombus in the portal vein, a novel approach in veterinary literature.
  • Temporary portal vein occlusion (15 min) was well tolerated, causing only transient small intestinal congestion without lasting hemodynamic compromise.
  • No intraoperative hemorrhage occurred following vascular isolation and venotomy repair with 5–0 polypropylene in a simple continuous pattern.
  • Postoperative complications were minimal, with only moderate pancreatitis managed medically and no portal hypertension observed on follow-up imaging.
  • Histopathology confirmed insulinoma, with no initial metastasis; CT at 6 months revealed hepatic and peritoneal metastases but no local recurrence at the venotomy site.
  • Portal vein luminal stenosis occurred post-repair but was clinically insignificant.
  • Advanced CT imaging and 3D printed modeling significantly enhanced surgical planning and anatomical assessment.
  • Surgical excision achieved good short-term outcomes, and the dog was alive and euglycemic one year later despite metastatic disease.
