Intramedullary fixation has been used in the treatment of fractures for more than 100 years. It has been used in my country since the end of the 1990s and has been widely used in clinical practice. It is an essential skill for orthopedic surgeons to make intramedullary interlocking nails. In this article, we will introduce intramedullary interlocking nails.
Introduction of intramedullary interlocking nails.

Open reduction and internal fixation for the treatment of fractures include extramedullary fixation and intramedullary fixation. The plate screw internal fixation technology belongs to extramedullary fixation. A built-in medullary cavity at the distal or proximal end of the bone has good biocompatibility and certain strength. In order to achieve the fixation of the fracture end, it is called intramedullary fixation. The intramedullary interlocking nails are divided into:
1. Elastic/rigid intramedullary interlocking nail
Elastic intramedullary interlocking nails have a long history in the treatment of axially stable fractures. It is usually necessary to place several intramedullary interlocking nails to obtain sufficient stability. For axially stable fractures, the elastic intramedullary interlocking nail has better axial stability, but its anti-torsion effect is weak, so it is not suitable for comminuted fractures. Elastic intramedullary interlocking nails include: Rush nail, Ender nail and the latest titanium elastic intramedullary nail.
2. Reamed/non-reamed intramedullary interlocking nail
Reaming, that is, expanding the diameter of the medullary cavity, is a major advance in the history of intramedullary nail development. The intramedullary interlocking nail can be inserted after reaming, or the nail can be inserted without reaming.
1. Intramedullary interlocking nails can control the axial line of force at the fracture site; locking intramedullary nails are more effective in preventing fracture rotation and reduce the risk of intramedullary nail fracture.
2. Adopting closed nail penetration technique, there is less soft tissue peeling, the fracture site can not be exposed, and the infection rate of the operation is reduced.
3. The closed piercing nail preserves the fracture hematoma and reduces the damage to the periosteum blood supply. At the same time, the debris generated during reaming is deposited on the fracture site, which has the effect of autogenous bone grafting.
4. Generally, the intramedullary interlocking nail does not need to be taken out. Even if it needs to be taken out, only a small incision is made at the corresponding place of the locking nail and one end of the intramedullary nail.
5. There is a stress dispersion effect between the intramedullary interlocking nail and the damaged bone to avoid stress shielding.
