Embodiment Construction

[0019] The tibial plateau three-column anatomical bone plate of the present invention comprises three parts: a bone plate body 1, a medial and lateral column fixation plate 2, and a posterior column fixation plate 3.

[0020] As shown in the figure, the bone plate body 1 is a long longitudinal plate surface, and the bone plate body 1 is fixed by screws along the length direction of the anterolateral side 8 of the proximal tibia. A plurality of fixing screw holes 7 are distributed along the length direction on the bone plate body 1. The fixing screw holes 7 are a double-hole connection structure, and the double holes are locking screw holes and common screw holes respectively. Screwed with locking screw and lag screw. The locking nail is combined with the thread of the locking screw hole to play a supporting role. It can be used with ordinary lag screws and self-tapping screws to better fix it.

[0021] As shown in the figure, the inner and outer column fixation plates 2 and t...

Abstract

The invention discloses an internal fixation plate for tibial plateau three-column dissection, and belongs to the technical field of bone operation instruments. The internal fixation plate is used for fracture fixation during tibial plateau three-column dissection; through an inner and outer column fixation plate at the upper end of the internal fixation plate, facture blocks at the outer and inner columns can be firmly fixed at the same time; meanwhile, a rear column fixation plate can be used for fixing facture blocks at an inner rear column on a medial tibial plateau, at a rear column on a lateral tibial plateau and at an outer rear column on the lateral tibial plateau. Therefore, the outer, inner and rear columns on the tibial plateau can be fixed at the same time through one internal fixation plate. The internal fixation plate has the advantages that a layered fixation structure is creatively provided, a brand new mode of multi-plane and three-dimensional fixation is provided as a breakthrough, and such a major and difficult clinical problem as a tibial plateau three-column facture is solved skillfully, so that operative wounds are greatly reduced, operative duration is greatly shortened, the incidence of intraoperative and postoperative complications is greatly reduced, early facture healing and early functional exercise are facilitated, and a better treatment effect can be achieved.

Description

technical field [0001] The invention relates to a bone plate capable of fixing the three-column anatomical fracture of the tibial plateau, which belongs to the technical field of orthopedic surgical instruments. technical background [0002] Tibial plateau fractures are often encountered in clinical work. The purpose of surgical treatment is to fully reset the fracture block, restore the alignment of the lower limbs and the smoothness of the articular surface, and reconstruct the function of the knee joint. At present, the commonly used classifications of tibial plateau fractures are as follows: AO / OTA classification, Schatzker classification and three-column classification. The three-column classification makes up for the defect that the former two classifications do not involve posterior tibial plateau fractures. With the recognition of the "three-column theory" in the international academic community, new developments have been made in the treatment of posterior tibial p...
