Description

Outer ankle distal end locking plate

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a distal lateral malleolus locking plate.

Background

In the treatment of external malleolus fracture, doctors often adopt percutaneous placement or incision of a reduction fixing device to reduce and fix the fractured external malleolus together. The fracture of the external malleolus is reduced and tightly fixed together, so that the periosteum growth and the healing of the fracture are greatly accelerated. However, the existing steel plate screw fixing system is relatively large in size and cannot be well matched with the distal end of a fibula, and because local soft tissues at the position are less in coverage, skin necrosis exists, the internal fixation is exposed, the movement of an ankle joint is affected by the steel plate screw fixing system with the large size, the defect that the ankle joint is easy to stiff exists, the recovery of the function of a patient limb is not facilitated, in addition, a fracture block at the distal end of an external malleolus is often small, screw fixation cannot be usually used, and the reduction fixation of the small fracture block is relatively difficult.
