    摘要: A intramedullary nail of the type adapted to receive a conical drive connection is provided with a slot which extends from the tip to the head for improved elasticity. A locking section is provided at the head to avoid the nail spreading apart when a conical drive connection is used. The nail has a threaded conical socket to receive a drive connection and the thread is shaped to minimize radial forces resulting from driving bolt being screwed into the socket.
