Name two modifications of the Reverdin osteotomy (intra-articular closing adductory wedge osteotomy, preserving an intact lateral cortical hinge).
What is Green (horizontal plantar osteotomy made trough metatarsal head dorsal to sesamoid to protect the plantar surface and sesamoidal articular surfaces), Todd (Green + penetration of plantar cortex to enable sagittal plane correction), Laird (completion of osteotomy through lateral cortex allowing transverse plane translocation of the capital fragment to reduce the first IMA).
