Lower limb Locking Plate

Lower limb Locking Plate is a kind of implant fracture orthopedics with locking thread holes. 

The lower limb Locking Plate allows the bone to bind to the plate more firmly, so that the reduced limb is more stable. Locking Plates were first used in spine and maxillofacial surgery 20 years ago to stabilize fractures while reducing extensive dissection and damage to soft tissues. When the threaded hole in the locking plate is screwed in by a screw with a threaded head, the plate becomes an Angle fixing device. It can have both locking and non-locking holes for different screws to be screwed in. Any plate that can be screwed into an Angle fixed (stable) screw or bolt is essentially a locking plate.

Locking plate system does not rely on bone friction to achieve connection, but completely depends on the interlocking structure of the plate itself. A certain gap between the plate and the bone surface can be left, which can eliminate the adverse effect of heavy pressure contact between the plate and bone, and greatly improve the blood supply and the growth and recovery of the periosteum. The main biomechanical difference from conventional plates is that the latter relies on friction at the bone-plate interface to accomplish plate compression on bone. Stability is maintained by an angularly stable interface between the screw and the plate. Because the locking internal fixator has a stable integrity, the pull-out force of the locking screw is much higher than that of the ordinary screw. It is difficult for a single screw to be pulled out or broken unless all the surrounding screws are pulled out or broken.
