Abstract:
1. An intramedullary osteosynthesis and arthrodesis device for hand or foot bones and formed unitarily with a rigid central zone from opposite ends of which extend anchor zones each formed by a pair of legs extending symmetrically of a longitudinal axis generally bisecting the central zone, the legs each having a base portion fixed to the central zone and a tip forming the respective end, the end of one of the legs of a pair being independent of the other leg of the pair, the legs each further being deformable between a closed position for insertion of each of the pairs of legs into a respective bone and an open position for internally gripping the respective bone, the legs of each pair in the open position diverging away from the central zone and in the closed position converging away from the central zone so as to be more closely spaced at their tips than at their base portions, the base portions of each pair of legs in the closed position being angled inwardly towards one another, wherein an outer surface of each leg is curved at the tip and, in the open position, the outer surface of each leg is adapted to form an anchorage within the respective bones.
