Introduction：Ankle arthrodesis is a good resolution for painful,unstable, post-traumatic, arthritic joint. A wide variety of surgical options and approaches exist to treat the difficult problem of ankle arthrodesis. The success of the fusion depends on achieving and maintaining rigid fixation of prepared tibiotalar interface.

Materials and Methods：Case one wa an amputated patient at ankle level post replanation. Bone loss was noted at the same time. Case two was an ankle bimalleolar fracture post ORIF failure with severe ankle deformity. We performed ankle arthrodesis for these cases using lateral approach and internal fixation with A.O. locking plate.

The source of fusion bone stock was excised fibular shaft.

Results：These cases all achieved solid fusion and regain excellent walking capacity.

Discussion：Compared to screw fixation method, rigid fixation with locking plate can increase construct rigidity and decrease micromotion at tibiotalar fusion interface.

If subtalar joint was damaged, this technique could easily extended to tibiotalocalcaneal (TTC) arthrodesis.

Conclusion：We present a simple and reproducible technique for ankle arthrodesis that gives excellent clinical results.
