I.What are the complications of interlocking the femur nail?
Humerus interlocking nail system-multidimensional locking is a little different from humerus interlocking intramedullary nail system.
Humerus interlocking intramedullary nail system is consisted of humeral interlocking nail, humeral rotation blade, locking srcrew ,nail and cap and lengthened end cap. While humerus interlocking nail system-multidimensional locking is composed of humeral interlocking nail system-multidimensional locking (left and right types), Φ4.5 multidimensional locking screw, Φ3.5 locking screw, end cap and lengthened end cap.
What causes this difference between humerus interlocking nail system-multidimensional locking and humerus interlocking intramedullary nail system?
The multi-dimensional locking design can lock the fracture site in multiple directions, providing a more stable and reliable fixation effect, reducing the micro-movement of the fracture end, and facilitating fracture healing. It is more suitable for complex fracture conditions. The non-multi-dimensional locking interlocking intramedullary nail system of the femur is more suitable for simple fracture conditions.
II.What are the benefits of intramedullary nailing?
Humerus interlocking nail system-multidimensional locking is an advanced medical term for humeral fractures. Its advantages are reflected in the following aspects:
1)Special internal thread of screw to improve stability.
2)Double cortical screw increases the stability of transverse and short oblique fractures.
3)Make up of short nail and long nail and there are many kind of screws choose to solve the simple and complex fractures of proximal humerus and humeral axis. Consistent with the bone shaft, controllable dynamic design, micro movement, promote the union.
4)By adopting minimally invasive techniques, the surgical incision is relatively small, reducing damage to the surrounding soft tissues and lowering the risk of postoperative infection and complications.
5)It has good axial and rotational stability, can withstand a large physiological load, and is conducive to the early activity of patients.




III.When should I start therapy after humerus fracture?
Surgical treatment:
1) Intramedullary nailing: This is the preferred treatment for femoral shaft fractures, especially for young and active patients.
2) Plate fixation: For some complex fractures or patients not suitable for intramedullary nailing, plate fixation can be chosen.
3) External fixator: Mainly used for open fractures, patients with multiple injuries or those requiring temporary fixation.
4) Arthroplasty: For proximal femoral fractures, especially femoral neck fractures or subcapital fractures in elderly patients, hip arthroplasty may be necessary.
Non-surgical treatment:
1)Traction therapy: It is suitable for some patients who are not suitable for surgery, such as the elderly, those in poor physical condition, or those with severe internal diseases.
2)Plaster fixation or brace fixation: For some simple and non-displaced femoral fractures, plaster fixation or brace fixation can be adopted.
