indication:

All kinds of limb defects caused by trauma;

Patients with bone defect after partial removal of bone tissue due to bone pain and local osteomyelitis;

Chronic osteomyelitis, congenital tibial defect in children;

Bone defect was repaired after resection of bone tumor.

Biological principle:

Tissue engineering, composite tissue formation

Unnecessary tissues disappear or transform, and the needed tissues show high regeneration ability and regenerate according to the functional requirements of specific parts and tissues.

Irizarov's "guided bone regeneration" promotes tissue regeneration, development and osteoblast formation

"Guided bone regeneration" refers to the repair of defects in the process of bone transfer.

The basic methods are as follows

Bone defects were treated by moving the active bone block at a speed of 1 mm per day.

Bone regeneration and tissue regeneration are used to complete the treatment

It can complete the regeneration and repair of bone tissue, blood vessel, nerve and skin

Technical advantages:

In vitro operation, high safety factor

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

Compared with ring type and single rod type external fixator, it is easy to operate, stable and light, and can adjust bending and torsion angles.
