Abstract

A method of stabilizing a fractured bone includes: a) providing a first support member in a medullary canal of a fractured bone; b) providing a second support member outside the fractured bone; c) providing a transverse connector adapted to link the first support member to the second support member in an angle-stable connection; d) connecting the transverse connector to the first and second support members in an angle-stable connection; e) providing one or more bone screws adapted to be connected to the second support member in an angle-stable connection; and f) implanting the bone screws such that the shank of the screw is implanted in the fractured bone while the head of the screw is connected to the second support member in an angle-stable connection. The system provides superior fixation of long bones that allows for early functional range of motion without loss of alignment or fixation.

Claims6

Dependent claims

An assembly for reducing and stabilizing a fracture in a long bone, comprising:

a) an intramedullary nail having at least one radial aperture passing radially through the nail and adapted to receive a transverse connector in a locked, stable connection, and at least one axial aperture passing axially into the nail and adapted to receive a locking screw in a locked, stable connection;
b) a first locking plate having a first aperture adapted to receive a transverse connector in a locked, stable connection, and a second aperture adapted to receive a bone screw in a locked, stable connection;
c) at least one transverse connector having a head-end and a shank, the head-end being adapted to be received in the first aperture of said locking plate in a locked, stable connection, and the shank being adapted to be received in a radial aperture of said intramedullary nail in a locked, stable connection;
d) at least one bone screw having a head-end adapted to fit an aperture of said locking plate in a locked, stable connection;
and
e) a locking screw adapted to fit in the axial aperture of said intramedullary nail, and effective for locking the shank of a transverse connector to the intramedullary nail.
