Abstract:
The intramedullary expand self-locking nail(IESN) is a new type of solid small diameter nail consisting of the dynamic and the static types, designed on the basis of the CAIN. The mechanical experiments showed that its stiffness to resist the bending and twisting momentum was simillar to the Russell -Taylor's nail. The static nail was stable enough to prevent axial displacements of the fractured segments. The main characteristics of the IESN are as follows: 1) It is being able to be inserted without reaming the medullary cavity and without X- ray guidance; 2) a higher limit value to resist fatique and 3) no stress concentration on IESN.
