Placement of distal interlocking screws into femoral and tibial nails
is an exacting technique. Many techniques are described, each with the
ir advantages and disadvantages. We describe an alternative technique
using the ''third point in space.'' This method has been successfully
used in >30 cases. It is universal, reproducible, and inexpensive, avo
iding the use of distal targeting guides, expensive radiolucent drills
, or visual estimations of alignment.
