Quiz Question
In Anderson 2023 et al., on French Bulldogs with humeral condylar fractures, what fixation method was associated with the highest risk of major complications in French Bulldogs?
🔍 Key Findings
- Lateral humeral condylar fractures (LHCF) were most common, comprising 63.6% of cases.
- Transcondylar screw (TCS) + K-wire(s) fixation had a 7.62x higher risk of major complications compared to other methods (p = .009).
- All cases of TCS migration occurred in the TCS + K-wire group; none occurred with plate fixation.
- Overall complication rate was 40.9%, with 29.5% being major and requiring intervention.
- Contralateral humeral intracondylar fissures (HIF) were found in 58.1% of French Bulldogs with CT data.
- No significant association between age and presence of HIF, but fissure length increased with age (R = 0.47, p = .048).
- Younger, lighter dogs had higher complication and screw migration rates, possibly due to softer bone and smaller condyles.
- TCS + plate fixation had the lowest complication rate, suggesting biomechanical superiority.

In Lomas 2025 et al., on hybrid THR in cats, which component combination was used in all cases?
🔍 Key Findings
- Hybrid THR in cats showed no major complications across 17 hips in 15 cats, including 2 bilateral cases.
- Postoperative radiographs confirmed stable implant positioning with no loosening, migration, or dislocation in follow-up imaging.
- Mean owner satisfaction was high, with a mean short-form feline musculoskeletal pain index (sf-FMPI) score of 2/36 at a mean follow-up of 438 days.
- SCFE (slipped capital femoral epiphysis) was the most common indication, seen in 13/17 hips.
- Partial tenotomy of rectus femoris origin resolved intraoperative medial patella luxation in 3 cases—no cats required surgical correction later.
- A micro BFX cup allowed for increased acetabular offset, possibly reducing luxation risk even when using a +0 femoral head offset.
- Hybrid THR was successfully used as a revision for failed CFX THR due to recurrent luxation—implants remained stable post-revision.
- Use of oversized cups (12 mm) with shallow seating or medial breach still resulted in stable outcomes, suggesting good implant fixation even with reduced bone stock.

In McLean 2024 et al., why might ECA not have correlated with rock-back in this study?
🔍 Key Findings Summary
- 95 TPLO procedures reviewed retrospectively with follow-up radiographs
- Rock-back defined as increase in tibial plateau angle (TPA) ≥2° from immediate post-op to recheck
- 21% of stifles (20/95) experienced rock-back
- Mean ΔTPA among rock-back cases = 3.2° ± 2.6°
- No implant failures or tibial tuberosity fractures were reported in these cases
- Plate inclination and exit cut angle (ECA) were not associated with increased risk of rock-back (p = 0.4 and 0.2)
- Authors hypothesize that compression across osteotomy in vivo may mitigate torsional effects from ECA, unlike in gap-model studies
- Emphasizes that rock-back is relatively common, even with well-placed implants

In Gollnick 2024 et al., on TCTF risk with Arthrex STS in TPLO, which factor most contributed to serious tibial fracture following TCTF?
🔍 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 Marturello 2023 et al., on 3D-printed humeral models, which anatomical region had the **highest model accuracy** across all printer types?
🔍 Key Findings
- 3D-printed models using desktop printers (FDM, LFS) showed submillimetric accuracy, comparable to or better than industrial-grade PJP printers.
- Bone size had a greater effect on print accuracy than printer type, especially in proximal humerus regions.
- The humeral condyle region showed the greatest model accuracy, with mean differences under 0.5 mm, regardless of printer.
- Models tended to be slightly smaller than cadaveric bones, potentially due to systematic underestimation during printing.
- FDM printer provided the highest accuracy at the humeral condyle in medium-sized bones (+0.09 mm).
- LFS printer produced prints faster and more reliably than FDM, although both had comparable dimensional accuracy.
- Statistically significant differences existed, but all were submillimetric and unlikely to impact surgical outcomes.
- Desktop printers are suitable for surgical planning, including plate pre-contouring and patient-specific instrumentation.

In Deprey 2022 et al., on gap fracture implants, which material was the NAS-ILN made of?
🔍 Key Findings
- NAS-ILN had significantly greater stiffness in both axial compression and 4-point bending compared to LCP constructs.
- Ultimate load to failure was significantly higher for NAS-ILN in compression (804 N vs 328 N) and bending (25.7 Nm vs 16.3 Nm).
- Torsional stiffness and angular deformation were similar, but NAS-ILN resisted higher torque to failure than LCP (22.5 Nm vs 19.1 Nm).
- No slack was observed with the NAS-ILN construct, unlike older nail designs.
- Failure modes differed: LCPs failed via plate bending; NAS-ILNs failed at the implant or bone near screw holes.
- Titanium alloy and curved design of NAS-ILN provides better anatomic fit and more uniform stress distribution.
- A third, perpendicular locking hole in NAS-ILN may enhance torsional stability but was not utilized in this study.
- The curved, angle-stable design of NAS-ILN is a novel advancement in veterinary orthopedics.

In Raleigh 2022 et al., on pericardiectomy complications, which surgical tool was most frequently associated with the onset of ventricular fibrillation?
🔍 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.

In Foster 2026 et al., on right hepatic lobectomy, which surgical method was associated with increased complication risk?
🔍 Key Findings
- Perioperative mortality rate was low (2.9%), with no intraoperative deaths reported.
- Intraoperative complications occurred in 54.3% of dogs, most commonly hemorrhage and cardiovascular events.
- 21% of dogs required blood transfusions, though transfusion was not associated with higher complication risk.
- Advanced hemodynamic support (fluid + cardiovascular) was significantly associated with short-term complications (OR 17.3, p = .029) and shorter survival.
- No surgical method (e.g., TA stapler, vessel sealing device, hilar resection) was associated with increased risk of complications.
- Hepatocellular carcinoma (HCC) was the most common diagnosis (53%), with an MST of 741 days and 17.6% recurrence.
- Surgical margins (complete vs incomplete) were not associated with overall survival time in dogs with HCC.
- The use of preoperative CT and improved surgical instrumentation may have contributed to the lower observed mortality.

In Alvarez 2024 et al., which method produced significantly more caudal compression than Kern forceps alone?
🔍 Key Findings Summary
- F + P (forceps + plate compression) achieved the most uniform, high-pressure distribution across all quadrants.
- Kern forceps alone concentrated force in craniomedial quadrant, reducing caudal compression.
- Combining Kern + F improved craniolateral compression but did not restore caudal compression.
- Plate compression alone yielded caudal bias, not uniform pressure.
- Significant inter-method variation in quadrant-specific compression confirmed via ANOVA (p < 0.001 for all quadrants).

In Kimura 2025 et al., on mini-THA in <4 kg dogs, which intraoperative tool improved acetabular and femoral positioning?
🔍 Key Findings
- Zurich mini-cementless THA was successful in 9/10 hips in dogs <4 kg, with no lameness at 52 weeks in completed cases.
- Helsinki Chronic Pain Index significantly improved from a mean of 19.8 to 2.3 at 52 weeks (p = 0.0141).
- Fluoroscopy improved implant positioning, especially in LCPD and HD cases, aiding in accurate reaming and alignment.
- Intraoperative complications occurred in 2/10 cases, including acetabular fractures; one case required discontinuation.
- Prophylactic bicortical screws and reinforcement plates were used in cases with rotational instability or cortical compromise and were effective in preventing loosening/fractures.
- Medial patellar luxation improved postoperatively in one dog, though recurrence was noted later without surgical correction.
- No stem or implant loosening or fracture occurred over a mean follow-up of 24.4 months.
- CT is recommended in preoperative planning, particularly in luxoid hip dysplasia cases with uncertain bone stock.
