🔍 Key Findings Summary

• Retrospective study of 33 fractures in 31 cats with Salter–Harris I or II distal femoral fractures
• Used 1 intramedullary Steinmann pin + 1 laterally placed antirotational pin
• 96.9% achieved full functional outcome at mid-term follow-up
• No implant migration or removal required
• Minor complications: 2 seromas; Major: 3 (patellar luxation [2], osteomyelitis [1])
• Growth plate remained open in 27.3% of cases at 6–8 weeks post-op

🔍 Key Findings

• A linear relationship was observed between wedge angle and tibial plateau angle (TPA) correction across all four CCWO techniques.
• All techniques produced predictable TPA corrections using linear regression-derived equations, allowing wedge angle extrapolation to achieve a target postoperative TPA of 5°.
• TLA shift (tibial long axis) increased with wedge angle and influenced final TPA; greatest in Frederick & Cross method.
• Tibial shortening (mTL%) varied by technique, being most severe (up to 40.9%) in traditional Slocum & Devine CCWO and least in newer techniques (7.5–12%).
• The Oxley mCCWO technique showed lower TLA shift compared to the Frederick & Cross and Christ techniques, though similar to Slocum & Devine; tibial shortening was more pronounced than other modified techniques at wedge angles ≤40°.
• Techniques varied in craniocaudal translation and wedge apex positioning, influencing planning accuracy and mechanical axis alignment.
• The corrective wedge angle equations reliably predicted TPA within 4–6° across varied tibial conformations.
• The study supports equation-based planning over static TPA–5° subtraction to reduce risk of under- or over-correction.

🔍 Key Findings

• 78% of cats that developed postattenuation neurologic signs (PANS) after congenital portosystemic shunt (cPSS) surgery survived to 30 days.
• Postattenuation seizures (PAS) were associated with significantly decreased 30-day survival (50% vs. 78%; OR: 0.015, p = .005).
• Treatment of PANS with propofol was a negative prognostic factor (OR: 0.112, p = .0008).
• Generalized PAS accounted for most seizure cases and were more frequently fatal than focal or unknown-type seizures.
• Pretreatment with levetiracetam (LEV1 protocol) showed a trend toward improved survival (100% vs. 60.6% in untreated cats), though not statistically significant (p = .06).
• Shunt morphology, method of attenuation, and study period (early vs. late) were not significantly associated with 30-day survival.
• Electrolyte, glucose, and ammonia abnormalities were not strongly linked to survival outcomes in this study.
• Majority of PAS-related deaths were due to uncontrolled generalized seizures or euthanasia because of severity.

🔍 Key Findings

PL-30 group (partial, TA30-V3 wedge):

• 100% leaked
• Median leakage pressure: 10 cm H₂O
• Most failures from periphery of staple line

PL-60 group (partial, TA60-3.5):

• 100% leaked
• Median leakage pressure: 18 cm H₂O
• Better than PL-30 (p = .006)

TL-30 group (total, TA30-V3):

• Only 1 of 11 leaked (at 22 cm H₂O)
• All others resisted pressures >50–65 cm H₂O
• Significantly higher leakage pressure than both PL groups (p < .001)

Odds ratios (leakage vs TL-30):

• PL-30: OR 437 at both 20 and 30 cm H₂O (p = .003)
• PL-60: OR 437 at 20 cm H₂O and 133 at 30 cm H₂O (p = .003)

Recommendation: Prefer TL-30 when possible. If partial needed, PL-60 superior to PL-30, but all partials leaked at physiologic pressures.

🔍 Key Findings

• 3D CT volume rendering and CAL measurement successfully guided correction of femoral and tibial torsion in dogs with patellar luxation (PL).
• Physiological patellar tracking was restored in 100% (22/22) of cases after detorsional osteotomy.
• 94% of dogs (17/18) had either full or acceptable functional outcomes post-surgery.
• CAL-based correction was accurate in 19/22 cases, confirming reliability of the measurement technique.
• Complication rate was 45%, with major complications in 2/22 cases—both involved combined femoral and tibial osteotomies.
• Combined femoral and tibial osteotomies in the same limb were linked to a higher risk of complications and poorer outcomes.
• Diaphyseal osteotomies offered more implant space, but metaphyseal locations were associated with faster bone healing.
• Use of a TPLO jig or goniometer was not essential—CAL-based bone marking was sufficient in most cases.

🔍 Key Findings

• Augmenting FEESA with two simple interrupted crotch sutures (TCS) or simple continuous crotch suture (SCCS) significantly increased initial leakage pressure (ILP) compared to no suture or a single suture (NCS, SICS).
• SCCS had the highest ILP (47.6 mm Hg), followed by TCS (37.8 mm Hg), SICS (33.0 mm Hg), and NCS (27.1 mm Hg).
• All crotch suture types increased maximal leakage pressure (MLP) compared to no crotch suture.
• Leakage from the crotch occurred most commonly in NCS (67%) and SICS (50%), but only 8% with TCS and 0% with SCCS.
• SCCS was the only technique where leakage never occurred at the crotch site.
• SCCS had the highest MLP (100.6 mm Hg), supporting its use in clinical settings with high-risk patients.
• Intraluminal pressures during leakage in NCS constructs were sometimes below normal physiologic pressures, emphasizing risk of leakage without crotch suture.
• The transverse staple line never leaked in any group, indicating the crotch is the primary weak point.

🔍 Key Findings

• 12-hole LCPs (80% plate–bone ratio) showed significantly higher construct stiffness than 6-, 8-, or 10-hole plates in both compression and tension bending.
• Strain on the plate was significantly lower in 12-hole vs 6-hole plates at all regions of interest (ROIs), especially around the fracture gap.
• No incremental increases in stiffness or decreases in strain were observed between 6-, 8-, and 10-hole plates—only when comparing to 12-hole plates.
• Bone model strain adjacent to the plate end was significantly lower for 10- and 12-hole plates vs 6-hole plates under both loading conditions.
• The threshold effect suggests biomechanical benefits only emerge beyond a plate–bone ratio of ~80%.
• Working length increased from 9.4 mm (6-hole) to 13 mm (others), potentially influencing strain/stiffness differences.
• Four-point bending was used, as it replicates the most biomechanically relevant force on plated long bones.
• Clinical implication: Longer plates may reduce plate strain and peri-implant bone strain, potentially lowering risk of fatigue failure or stress risers.

🔍 Key Findings

• 3D-printed, SOP plate-specific guides enabled safe screw placement from T12–L5 in canine cadavers and models.
• All 140 screw trajectories were classified as Zdichavski Grade 1, indicating optimal placement without vertebral canal breach.
• Screw angles (cranial-caudal and transverse) matched preoperative planning, with no significant deviation.
• Entry/exit point deviations were <1 mm on average, deemed clinically negligible.
• Drill guides were quick to place (<30 sec per vertebra) and improved ease of surgery.
• Plates acted as effective reduction tools, guiding alignment during screw placement in mobile spines.
• Minor technical challenges arose from cadaveric spine mobility, mitigated by sequential screw insertion.
• Technique may enable future use in fracture/luxation reduction, pending further cadaveric and clinical trials.
