Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a small splint fixing device for distal radius fracture. Background Art

[0002] Distal radius fracture refers to a fracture within 3 cm of the articular surface of the lower end of the radius. This part is the junction of cancellous bone and compact bone, which is an anatomically weak part. Once subjected to external force, it is easy to cause a fracture. The distal radius wrist joint is formed through the lunate fossa, scaphoid bone, scaphoid fossa, etc., and through the distal ulna and sigmoid notch to form the distal radioulnar joint. This joint is mainly fixed by triangular fibrocartilage, which can effectively maintain the function of the distal radioulnar joint.

[0003] After the treatment of patients with distal radius fractures is completed, a splint is generally installed at the radius to protect the radius to prevent the radius from being subjected to external force again and causing secondary injury. However, the existing small splints for bone setting are generally set to two symmetrical ones in front and back, and the two splints are connected together by Velcro. However, the fixation effect of only connecting with Velcro is poor. When the Velcro fails or is damaged, the splint will fall apart, affecting the protective effect. For this reason, we propose a small splint fixation device for distal radius fractures. Utility Model Content
