Embodiment 1

[0060] see Figure 1-Figure 18 As shown, the present embodiment provides a rotary prosthesis of the radial and ulnar distal forearm, including a first part 11 and a second part 12;

[0061] The first part 11 and the second part 12 are connected, and the first part 11 and the second part 12 can rotate relatively along the joint;

[0062] The side of the first part 11 away from the second part 12 is provided with a first fixing part 21;

[0063] A second fixing portion 22 is provided on a side of the second portion 12 away from the first portion 11 .

[0064] For patients with dislocation of the radioulnar joint of the forearm, the head of the distal ulna is resected, or the neck near the distal end of the ulna is amputated to separate the distal and proximal ends of the ulna. If the head of the distal ulna is resected, the first part is fixedly connected to the distal radius through the first fixing part, and the second part is fixedly connected to the proximal ulna through t...

Abstract

The invention relates to the technical field of medical prosthesises, in particular to an ulnoradial far end front arm rotary prosthesis. The ulnoradial far end front arm rotary prosthesis comprises afirst part and a second part; the first part is connected with the second part, and the first part and the second part can oppositely rotate along the junction; a first fixing part is arranged at theside, away from the second part, of the first part; a second fixing part is arranged at the side, away from the first part, of the second part. The purpose is to provide the ulnoradial far end frontarm rotary prosthesis to solve the technical problem that the treatment scheme for distal radioulnar joint dislocation existing in the prior art cannot recover the rotation function of the front arm or the rotation is unstable.

Description

technical field [0001] The invention relates to the technical field of medical prosthesis, in particular to a rotary prosthesis for the forearm at the distal end of the radius and ulna. Background technique [0002] The forearm bone is composed of the ulna and the radius. The two bones are connected by the interosseous membrane, the far and near superior radioulnar joint ligament and the joint capsule. The proximal and distal superior and inferior radioulnar joints are in position. Provides the power to pronate and supinate the forearm. The rotation mechanism of the forearm is that when the ulna remains fixed, the radius rotates with the rotation axis of the forearm relative to the ulna. to rotate around the axis of rotation. The axis of rotation and the axis of the long bone of the ulna are two different straight lines. [0003] Old DRUJ dislocations caused by trauma or degenerative lesions, wrist pain caused by impact, and a series of clinical symptoms caused by DRU mov...
