INTRAMEDULLARY PIN FOR DYNAMIC OSTEOSYNTHESIS WITH A SELF-LOCKING DISTAL END FOR FRACTURES

INTRAMEDULLARY PIN FOR DYNAMIC OSTEOSYNTHESIS WITH A SELF-LOCKING DISTAL END FOR FRACTURES

The intramedullary pin (1) has a proximal stub (2) transversed by at least one hole (3) with a transverse axis along which the stem (4) of a cervical spongiosa pin (6) or screw (5), rigidly coupleable to a neck-head of a damaged bone, is slidably longitudinally guided. The ends of curved and elastic...

Zusammenfassung:The intramedullary pin (1) has a proximal stub (2) transversed by at least one hole (3) with a transverse axis along which the stem (4) of a cervical spongiosa pin (6) or screw (5), rigidly coupleable to a neck-head of a damaged bone, is slidably longitudinally guided. The ends of curved and elastically deformable stems (11) having tips are axially rigidly coupled to the stub (2). The stems (11) are provided with a member for keeping the tips of the stems (11) mutually adjacent during the insertion of the pin (1) into a medullary canal through an apex of a greater trochanter, and for releasing the tips when the pin (1) is in a correct position in order to allow the stems (11) to elastically spread apart.
