🔍 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

🔍 Key Findings

From Allaith et al., 2023 – Outcomes from a multiuser canine hip replacement registry

• 2375 total hip replacements were analyzed across 1852 dogs, making this the largest multiuser canine THR dataset to date.
• Most common indications for THR were hip dysplasia (51%) and osteoarthritis (34%).
• Implants used included Kyon (46%), BioMedtrix CFX (22%), Hybrid (11%), BFX (9%), and Helica (4.5%).
• Veterinary-reported complication rate was 8.5%, while owner-reported was 23%, with moderate agreement (k=0.44).
• Most common complications: Luxation, femoral fracture, and aseptic loosening.
• BioMedtrix BFX and Helica implants had a higher risk of complications when used after femoral head and neck excision (P = .031).
• Postoperative LOAD scores significantly improved vs preoperative (21 → 11; P < .0001), supporting improved mobility.
• Owner satisfaction was high, with 88% rating outcome as very good or good.

🔍 Key Findings

• Fluoroscopically guided normograde metabone pinning (FGNMP) was used to treat 17 animals (15 dogs and 2 cats) with 57 metabone fractures, including various fracture configurations (short-oblique body, physeal, and comminuted).
• All 57 fractures were stabilized using intramedullary pins via FGNMP. The study exclusively focused on pin fixation and did not include screws or combined fixation techniques.
• Median surgical time was 54 minutes (range 26–99 min), indicating efficient procedural execution.
• Radiographic bone union was achieved in all fractures, with a median time to union of 6 weeks (range 4–12 weeks). Union was confirmed in all initially non-united fractures on follow-up.
• No major complications were reported. A single pressure sore at the olecranon resolved uneventfully, and no pin migration or osteomyelitis was observed.
• Pin extensions were noted radiographically (e.g., 42% distal subchondral overextension), but were not associated with clinical problems.
• Fluoroscopic guidance improved implant accuracy and preserved soft tissue, enabling effective fracture alignment and stabilization using this minimally invasive osteosynthesis (MIO) approach.
• The authors concluded that FGNMP is an effective, safe, and minimally invasive method for a variety of metabone fracture types, yielding quick recovery, fast healing, and good to excellent long-term functional outcomes in all 17 cases.

🔍 Key Findings

• TPLO mRUST scoring showed improved inter-rater reliability (ICC = 0.56) compared to subjective evaluation (Kappa = 0.33).
• Intra-rater reliability was similar for both methods (TPLO mRUST: 0.73, subjective: 0.72).
• TPLO mRUST scores ≥10/12 strongly correlated with radiographic union, as subjectively assessed (99% agreement).
• No significant difference in healing between first and second TPLO sides (P = .09), countering assumptions about load-bearing impact.
• Higher initial lameness scores and younger age were associated with higher TPLO mRUST scores, suggesting more robust healing in those groups.
• Postoperative complications were linked to lower TPLO mRUST scores, indicating impaired healing.
• Medial cortex was excluded from scoring due to plate obstruction, validating use of only 3 cortices for scoring.
• The TPLO mRUST system may standardize healing assessment, reducing subjective bias across specialties.

🔍 Key Findings

• Modified percutaneous cystolithotomy (PCCLm) resulted in significantly shorter skin incisions and hospitalization duration compared with open cystotomy (OC) (p=.002 and p=.031, respectively).
• PCCLm cats had fewer immediate postoperative lower urinary tract signs and were more often asymptomatic postoperatively than OC cats (p=.046 and p=.006).
• Rates of incomplete urolith removal were similar between PCCLm and OC, indicating no clear advantage in stone clearance for either technique.
• No PCCLm procedures required conversion to open surgery, demonstrating technical feasibility in cats.
• Clinical urolith recurrence rates were low and similar between PCCLm (10.5%) and OC (8.6%).
• In PCCLm, incomplete stone removal was associated with longer anesthesia time, longer hospitalization, larger incision length, and postoperative LUTS.
• In OC, incomplete stone removal was associated with longer surgery time and obstructed/distended bladders at presentation.
• PCCLm is an acceptable minimally invasive alternative to OC, although it did not reduce surgical site infection rates or incomplete stone removal.

🔍 Key Findings

• Quadriceps muscle length/femoral length ratio (QML/FL) was significantly lower in dogs with grade IV MPL than grades I–III (p ≤ .002).
• Shortened QML was associated with increased femoral torsion angle (FTA) and increased aLDFA, indicating correlation with femoral deformity.
• QML/FL increased with age, possibly due to muscular development or reduced deformity in older dogs (p = .004).
• Grade IV MPL dogs had QML/FL < 0.87, the lower normal limit based on healthy beagles, suggesting clinically significant muscle shortening.
• PLL/PL ratio (used to diagnose patella alta) was not associated with QML/FL or MPL severity in small breeds.
• QML/FL can help preoperatively identify candidates for femoral shortening ostectomy, improving femoropatellar alignment.
• Multivariate regression model confirmed QML/FL is independently influenced by age, FTA, and aLDFA (R² = 0.45).
• CT-based 3D measurements enabled objective, noninvasive quantification of femoral and muscle alignment parameters.

🔍 Key Findings

• Ventricular fibrillation (VF) occurred in 3% of pericardiectomy cases across reporting institutions.
• 14 of 16 dogs (88%) that developed intraoperative VF died, indicating high mortality.
• Electrosurgical devices were used in 15/16 dogs; VF onset coincided with their use in 8 dogs, suggesting a potential but unproven association.
• Preoperative arrhythmias were seen in 7 dogs (e.g., VPCs, VT, bradycardia), possibly serving as early warning signs.
• Thoracoscopic approach was used in 75% of cases; however, conversion to open surgery was required in 9/13 thoracoscopic procedures after VF onset.
• Defibrillation was attempted in 13 dogs, but only 3 converted to sinus rhythm, and only 2 survived postoperatively.
• VF may result from stray current or cardiac manipulation; bipolar energy devices were implicated despite lower theoretical risk.
• Preventative strategies include judicious electrosurgery use, close ECG monitoring, rapid CPR preparedness, and preop cardiac risk assessment.

🔍 Key Findings

• Use of smoke evacuators reduced ultrafine particle concentrations by 56.4% during approach to the proximal tibia for TPLO in dogs.
• Mean intraoperative particle concentrations were significantly higher in surgeries without smoke evacuation (1352 ppc vs. 763 ppc, P < .0001).
• Maximum particle concentrations were six times higher without smoke evacuation (62,450 ppc vs. 10,100 ppc, P < .0001).
• Particle counts increased above baseline regardless of evacuator use, confirming electrosurgery contributes substantially to airborne particles.
• Surgeons noted reduced odor and health concerns when using the smoke evacuator, despite initial visibility limitations due to pencil attachment.
• Standard surgical masks do not protect against ultrafine particles, underscoring the importance of smoke mitigation systems.
• The smoke-evacuation unit did not eliminate all ultrafine particles, suggesting optimization (e.g., higher power setting) may be beneficial.
• This is the first clinical veterinary study to measure surgical smoke reduction using evacuators during TPLO.

🔍 Key Findings

• Minimally invasive repair of acetabular fractures using precontoured plates on 3D-printed models is feasible and technically reproducible in dogs.
• All cadavers had fracture gaps <2 mm and step defects <1 mm, indicating accurate reduction.
• Sciatic nerve injury was minimal or absent in all cases, supporting potential neuroprotection from indirect approaches.
• Pelvic angulation was maintained <5°, confirming preservation of alignment post-reduction.
• Surgical time averaged ~46 minutes in cadavers for both approaches and repair.
• Clinical case showed good radiographic healing by 8 weeks and full union by 3 months, with early weight-bearing post-op.
• Use of locking screws improved reduction fidelity, particularly across a broad plate span.
• 3D printing accelerated surgical planning, though its necessity remains debated due to the availability and cost concerns.
