indication:

It is suitable for external reduction and fixation of limb fractures and fractures caused by trauma.

Biological principle:

According to the tension stress rule, tissue regeneration and reconstruction were stimulated.

Under the action of chronic tensile stress, any tissue shows strong regeneration ability

Under the principle of minimally invasive, external fixation device was used to form a composite system with bone needle and bone.

A stable system of space mechanics is formed.

The basic methods are as follows

In order to fix the fracture, the proximal and distal ends of the fracture were inserted and inserted through the skin.

Technical advantages:

It does not destroy periosteum and blood circulation.

There is no need for bone grafting and internal fixation to peel off and partially remove the fracture end, so as to avoid new bone infection and bone defect.

It is easy to operate in vitro.

The cure rate is high, the curative effect is reliable, and the second operation is not needed.
