Advantages of intramedullary nail

1. can control the axial force line of fracture site, and interlocking intramedullary nail can prevent fracture rotation deformity and reduce the risk of implant fracture;

2. Adopt closed minimally invasive technology to reduce the infection rate of operation;

3. Reducing the damage to periosteal blood supply, retaining osteogenic growth factor in hematoma, autogenous bone grafting of reaming fragments, and providing mechanical stimulation by muscle contraction to promote fracture healing;

4. Central fixation, elastic fixation and stress dispersion avoid stress shielding, and the incidence of re-fracture is low;

5. Firm fixation can be used for early functional exercise and weight bearing;

6. Small incision for internal fixation, minimally invasive;
