Description

Technical Field

[0001] This utility model relates to the field of nail plate technology, specifically a nail plate for the tibia. Background Technology

[0002] The tibia is a vital bone in the lower limbs, a long bone on the medial side of the lower leg, consisting of a tibia and two ends. The proximal end forms the knee joint with the tibia, while the distal end forms the ankle joint with the talus and fibula. Therefore, the tibia plays a crucial role in weight-bearing and as a major joint for movement. In trauma, the tibial plateau plays a vital role in the knee joint, so knee injuries often damage the tibial plateau, causing fractures, most commonly from car accidents and falls from heights. Tibial fractures require the use of plates and screws to repair and fix the fracture, promoting bone healing.

[0003] In fracture repair surgery, conventional fixation requires posterior fixation, resulting in a large surgical incision. It is difficult to perfectly avoid the posterior vascular and nerve bundles. Furthermore, it is necessary to fix a steel plate on the side of the fracture site and another steel plate on the back. This can lead to unstable fixation, a large surgical incision, and an excessively long recovery period. It can also cause secondary damage during the later removal of the plates and screws. Summary of the Invention
