Vascularized second metatarsophalangeal joint transfer offers a possibility to reconstruct the radial support which is lacking in radial dysplasia. Our experience from 1987 to 2017 with 34 congenital radial club hand reconstructions have allowed a possibility for long-term evaluation of the method. Compared with conventional methods, second metatarsophalangeal joint transfer results in better wrist mobility and does not restrict typical ulnar growth. The balance of the wrist remains good until age 11. Thereafter, the growth of the vascularized bone graft transfer matches only partially the distal ulnar growth in adolescence, resulting in mild recurrence of radial deviation. A new option to create a two-bone forearm in selected Bayne-Klug Type III radial dysplasia cases will allow a relatively good pro-supination ability. Potentially, a proximal fibular epiphyseal transfer could be a future solution. Currently, a safe harvest of the proximal fibula at childhood remains controversial.
