Abstract
The pin comprises a proximal stub (2) provided with elements (3) for fixing to the proximal cortices. The ends of at least two curved and elastically deformable stems (8) are rigidly associated axially to the stube (2). The stems (8) have at their free ends, temporary binding retention elements (10). These (10) are adapted to keep the tips (9) of the stems (8) mutually adjacent during the insertion of the pin (1) in the medullary canal through the metadiaphysis and to release the tips (9) when the pin is in correct position so as to allow the elastic expansion of the stems (8). The tips (9) anchor in the intramedullary spongy bone until they possibly press the inner walls of the bones producing an integral coupling between the synthesis arrangement and the bone.
