The locking plate is a fracture fixation device with a threaded hole. After a screw with a threaded head is screwed in the hole, the steel plate becomes a (screw) angle fixation device. Locking (angle stable) steel plates can have both locking and non-locking screw holes for different screws to be screwed in (also called combined steel plates).
Since the concept of locking steel plate was proposed and applied to fracture treatment, it has been widely used in peri-articular fractures due to its advantages such as providing stable support and fixation of fractures, higher fracture healing rate, less soft tissue damage and blood supply damage. , Fixation of comminuted and osteoporotic fractures. Today, I will give you a detailed introduction to the locking steel plate, which is worth learning!

1. What is a locking steel plate?
Any steel plate that can be screwed into an angle-fixed/angle-stabilized screw or bolt is essentially a locking steel plate.
2. Advantages of locking steel plate
Stable angle, resistance to bending and torsion
The screw head is conical to improve the mechanical distribution
Provide radial preload to prevent bone resorption and screw loosening
Anatomical type, adapted to local anatomy
Matching template, allowing percutaneous fixation of the backbone area (single cortex, self-drilling, self-tapping locking screw)
Regardless of whether it is elastically bridged or absolutely stable, the locking screw can provide a good anchoring effect
No need to be in close contact with the bone surface to preserve blood supply
Controlled fretting, beneficial to fracture healing
Generally, bone grafts are not needed, especially for osteoporotic fractures or any highly unstable fractures.
