Opening wedge low tibial osteotomy: a minimally invasive approach.

Valgus osteotomy of the distal tibia may decrease the symptoms of ankle osteoarthritis and halt the progression of degeneration by redistributing or decreasing joint contact stress. Classically, opening wedge low tibial osteotomy was performed as an open procedure and the osteotomy site was stabilised by K wires or medial plates. Potential complication of the medial wound can be disastrous. Wound breakdown can lead to exposure of the implant. We present a minimally invasive approach with osteotomy and bone grafting through a small posteromedial wounds and the osteotomy site is stabilized with MIPO (minimally invasive plate osteosynthesis) technique. This approach can minimize the soft tissue dissection and the potential wound complication.
