Problems solved by technology

Especially in the recent research results, it is pointed out that heterotopic ossification presents obvious symptoms in about 5% of patients with the disease and thus leads to the problem of limited range of motion of the joints. In addition, it can cause artificial pain due to severe joint pain Significant decline in joint function
In order to solve the above-mentioned problems, a surgical intervention method of surgically removing the hypertrophic bone is required, which in turn leads to an increase in the burden on the patient due to reoperation

Abstract

The present invention relates to an artificial ankle joint tibia component and, more specifically, to an implant being implanted in vivo. The implant comprises: a body part having a contact surface, which comes into contact with the cross section of the distal tibial joint, and a joint surface which faces the joint; and a fixing part extending at a fixed length upwardly from the contact surface. The fixing part comprises a blade which extends in a lateral direction and is formed in a single piece extending at a fixed length upwardly from the front-center of the contact surface. The blade comprises at least one rear blade unfolding at a predetermined angle with respect to the A-P line. Therefore, the present invention prevents stress concentration on one lateral blade and thus prevents breaks, enables extension of the contact surface area between the bone and the implant and thus enhances fixing force, and prevents marginal bone resorption by means of preventing rotation and distributing stress.

Description

technical field [0001] The present invention relates to an artificial ankle tibial element, in particular to an artificial ankle tibial element. The contact surface where the cutting surfaces of the articular surfaces meet and the articular surface facing the joint; and the fixed part is formed by extending a certain length from the upper side of the above-mentioned contact surface; wherein, the above-mentioned fixed part is extended from the front middle of the above-mentioned contact surface to the upper side Consisting of a single body formed at a certain length and including wings extended to one side, the wings include at least one rear wing spread out at a certain angle based on the front-to-back (AP) line, thereby preventing stress from concentrating on the side wing. It prevents it from breaking, strengthens the fixation force and prevents it from rotating by expanding the contact area between the bone and the implant, and prevents bone resorption around the wing by di...
