Introduction:
Distal femur fractures present significant surgical challenges due to their complex anatomy and limited soft tissue coverage. Minimally invasive plate osteosynthesis (MIPO) has emerged as a promising alternative to traditional open techniques, aiming to reduce soft-tissue damage while maintaining stable fixation, particularly when used with locking plates.
Materials And Methods:
This retrospective study analyzed 40 consecutive patients with distal femur fractures treated with MIPO and locking plates.
Results:
The results showed a high union rate of 92.5%, with fractures healing within 16-24 weeks (mean: 19.2 weeks). Complications occurred in 12.5% of cases, including three cases of malalignment, one case of screw breakage, and one infection. Functional outcomes were positive, with 85% of patients achieving excellent or good results based on the Knee Society Score, indicating satisfactory postoperative mobility and joint function.
Conclusion:
MIPO using locking plates is a reliable and effective treatment for distal femur fractures, offering high union rates, manageable complication rates, and favorable functional outcomes while minimizing soft-tissue disruption.
