Although described by Gattelier and Chastang in 1924, the transfibular approach to the ankle has been slow to emerge as a conventional orthopaedic technique. To date, applications have been confined to the treatment of tibiotalar arthrodesis, ankle joint incongruity and exposure of the fractured talus, where the distal fibula is also fractured. While seemingly undocumented, it is also proving effective in mosaic-plasty of the talus. This paper outlines an innovative technique of segmental distal fibula osteotomy and its role in the treatment of osteochondritis dissecans of the postero-lateral talar dome.
