Summary
# Editorial Summary Between 1999 and 2003, James and Richardson evaluated minimally invasive percutaneous plate osteosynthesis (MIPPO) as an alternative to conventional open approaches for lower limb fracture repair in 32 horses, comparing outcomes with matched cases treated by traditional techniques. The cohort included 22 horses with incomplete distal metacarpal/metatarsal condylar fractures (particularly those with spiralling or diaphyseal components), alongside 10 metacarpophalangeal arthrodeses and 4 pastern arthrodeses. Crucially, the minimally invasive group demonstrated lower surgical times, reduced infection rates, and improved survival outcomes compared with open procedures, though the sample size precluded statistical significance; notably, spiralling condylar fractures—typically considered problematic—were managed successfully without catastrophic displacement. For practitioners dealing with specific distal limb fractures and arthrodeses, MIPPO represents a technically demanding but potentially rewarding option that may meaningfully reduce post-operative morbidity and mortality by preserving soft tissue integrity and minimising bacterial contamination pathways. Future prospective work with larger cohorts would help establish which fracture patterns and patient presentations benefit most from this percutaneous approach.

Practical Takeaways
- •Minimally invasive plate fixation (MIPPO) is a viable alternative to conventional open approaches for distal limb fractures in horses, with potential advantages in reducing surgical site infections and complications
- •The technique can be effectively applied to spiralling condylar fractures and arthrodesis procedures, offering improved outcomes in selected cases
- •Consider minimally invasive approaches for lower limb fracture repair in horses as they appear to improve survival rates while reducing operative time and infection risk
Key Findings
- •32 cases of minimally invasive plate fixation were successfully performed between 1999-2003, including 22 distal condylar fractures and 10 arthrodesis procedures
- •Minimally invasive approach showed lower surgery times and infection rates compared to conventional open approaches, with higher survival rates
- •Spiralling condylar fractures with diaphyseal components were successfully managed without catastrophic fracture using MIPPO technique
- •No statistical significance was found between groups, but minimally invasive percutaneous plate osteosynthesis appears to reduce morbidity and mortality in equine fracture repair
