[Double interlocking elastic nailing for intertrochanteric fractures and various diaphyseal indications]

Double interlocking elastic pinning performed through a lateral and medial approach was designed to control the lateral rotation, as well as sinking of the nails. Locking both nails with a threaded pin and two bolts limits the secondary depression of the fracture by the S-shaped lateral nail. The secondary depression of the fracture was less than 1 cm in 91% of our cases. No surgical revision was necessary for sinking nails. The control of the lateral rotation was excellent in 91% and the internal rotation was less than 10 degrees. Protrusion of the nails into the joint occurred in 4 of our first cases and could be eliminated by avoiding the superior lateral sector of the femoral head. Results, taking into account the function, shortening and lateral rotation are good in 87.5% of our cases. After plate and intramedullary rupture of the screw, in repeated fractures, this technique may be used without excising the screw fragments. Proximal and distal shaft fractures of the femur are also indications in elderly patients when monopodal rehabilitation is impossible.
