Interlocking nail and micromovement / 中华创伤骨科杂志

ABSTRACT

As a main treatment instrument of limb fractures, the interlocking nail is used in two ways dynamic fixation and static fixation. The former has less stress shielding but lower satiability. The latter is just the opposite. Therefore, static fixation is the main choice in clinic. But because of the higher stress shielding, complications take place frequently. This article is to discuss the relationship between micromovement and fracture healing, and calls for a new kind of interlocking nail which has micromovement function.
