The double beanbag technique allows the surgeon to select the position
of the lower limb before an arthrodesis of the hip. During the procedure,
the surgeon can freely manipulate the limb, confident that it can be
replaced in the exact position that was chosen for the arthrodesis. The
technique is not cumbersome, and only commonly available equipment is
needed. For the method to be effective, there must be enough residual
motion of the hip to allow positioning and preparation of the skin. Also,
rigid internal fixation must be used to maintain the selected position of
arthrodesis at the conclusion of the operation.
