  • Threaded pin
    Patent number: 6261292
    Abstract: The invention relates to a threaded pin for holding together pieces of a fractured bone. The pin comprises a body having a distal end and a proximal end. The distal end has a first thread presenting crests and the proximal end has a second thread presenting crests. The first thread and the second thread being spaced apart by a smooth portion. The first and second threads are such that the pitch X of the first thread and the pitch Y of the second thread both decrease from the distal end (X1, X2, Y1, Y2) towards the proximal end (Xn, Xn−1; Yn, Yn−1). The diameter d of the crests of the first thread and the diameter D of the crests of the second thread both increase from the distal end (d1, d2; D1, D2) towards the proximal end (dn, dn−1; Dn, Dn−1), and the values are such that: X1>X2>Xn−1>Xn>Y1>Y2>Yn−1>Yn and Dn>Dn−1>D2>D1>dn>dn−1>d2>d1. The invention is applicable to repairing bones.
