Problems solved by technology

For anteromedial tibial plateau stress fractures, the existing medial plateau anatomical bone plate adopts the "bamboo raft" technique from inside to outside to fix medial fractures. At this time, the anterior collapse is still unstable, and it is easy to lose after reduction.

Embodiment Construction

[0035] The invention will be described in more detail hereinafter with reference to the accompanying drawings showing embodiments of the invention. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In these drawings, the size and relative size of some regions may be exaggerated for clarity.

[0036] The invention provides a main force support bone plate specially used for hyperextension and varus tibial plateau fractures. The main body part includes three parts: the proximal head (1), the middle connecting part (2), and the distal straight part (3). . The proximal head (1) wraps around the anteromedial column of the proximal tibial platform, and has a first locking screw hole, which can be placed into the first lockin...

Abstract

The invention relates to a main force support bone fracture plate special for hyperextension and introversion type tibial plateau fracture and belongs to the technical field of orthopedics-departmentmedical equipment design. The bone fracture plate has the advantages that the bone fracture plate is designed according to the anatomical structure of the tibial plateau anteromedial condyle, a main force support internal fixing effect on tibial plateau anteromedial stress fracture is achieved, and the bone fracture plate can favorably resist the anteversion and introversion trend of bone blocks and can well maintain the fracture reduction of the tibial plateau anteromedial column and reduce front bone sinking or introversion collapse; the tibial plateau anteromedial column anatomical bone fracture plate achieves the main force support and fixing of the tibial plateau anteromedial stress fracture through a body part, the head of the body part wraps and fixes the tibial near-end plateau anteromedial column, the internal fixing support effect and angle-forming stability of the body part provide a stable biological mechanical environment, and the bone fracture plate is firm and reliable as compared with an existing curved-surface bone fracture plate.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical device design, in particular to a main force support bone plate specially used for hyperextension and varus tibial plateau fractures, and the bone plate is designed based on the anatomical structure of the anteromedial condyle of the tibial plateau, and is an anatomical bone plate Lock the compression plate. Background technique [0002] Hyperextension injury-type tibial plateau fracture is a new type proposed by combining fracture morphological features and fracture injury mechanism. Knee hyperextension injury is rare in clinical practice, and its most notable feature is severe and high incidence of ligament injury, leading to knee joint dislocation, subluxation, instability, and prone to complicated posterior popliteal vessel and common peroneal nerve traction injuries. It may endanger the survival and functional recovery of limbs and must be given great attention. [0003] Professo...
