Lederer et al: Retrospective comparison of minimally invasive plate osteosynthesis and open reduction and plate stabilization of antebrachial fractures in 105 dogs (2017–2022)
Veterinary Surgery 4, 2025

🔍 Key Findings

Study size: 105 dogs (73 ORPS; 32 MIPO)

MIPO vs ORPS differences:

• Surgical time: MIPO median 130 min vs ORPS 85 min (p < .001)
• Explant rate: MIPO 25% vs ORPS 4.1% (p = .003)
• Time to clinical union: MIPO 85 days vs ORPS 57 days (p = .010)
• Frontal alignment deviation: MIPO 3.5° vs ORPS 2.0° (p = .047)
• Comminution more frequent in MIPO (41% vs 16%; p = .012)

Significant predictors for MIPO use: More proximal fracture margin (p = .004), surgeon identity (p < .001)

No significant difference: Sagittal alignment, radial length, union rate, or complication rate by surgeon

Implant preference: Fixin plates used in 84% of MIPO; locking plates more common in ORPS
