Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a forearm supination brace. Background Art

[0002] For patients with distal radioulnar joint injuries, especially those with anterior subluxation of the distal radioulnar joint, it is clinically necessary to fix the forearm in a supinated position (i.e., the palm is facing up) and the elbow is flexed 90 degrees. Generally, a plaster brace is used for fixation. However, plaster brace fixation is inconvenient for patients in their daily lives. Currently, there are wrist braces and elbow braces on the market (including those with adjustable or fixed elbow flexion positions), but there is no brace that can simultaneously fix the elbow joint in a 90-degree flexion position and the wrist joint in a supinated position. Utility Model Content
