1, price

The price of imported steel plates is high, while the price of domestic steel plates is low.

2. Quality

Imported steel plates have high quality standards, high strength and toughness, and are not easy to break.

The quality of domestic steel plates is uneven, and the quality of steel plates in small factories is poor.

Step 3 refuse

The microstructure reaction of imported steel plate is small.

The rejection rate of domestic steel plates is greater than that of imported steel plates.

Locking steel plate is a kind of fracture fixation device with locking threaded hole. Locking steel plate makes the combination of bone and steel plate stronger, and makes the severed limb more stable after reduction. Locking plate was first used in spinal surgery and maxillofacial surgery 20 years ago to stabilize fractures and reduce extensive peeling and injury of soft tissue.

The fixation of steel plates does not rely on bone friction to realize the connection, but depends entirely on the interlocking structure of steel plates themselves. A certain gap can be left between the steel plate and the bone surface, which eliminates the adverse effect of excessive contact between the steel plate and the bone and greatly improves the blood supply and the growth and recovery of periosteum. The main biomechanical difference between the steel plate and the traditional steel plate is that the latter relies on the friction of the bone-steel plate interface to complete the compression of the steel plate on the bone.
