Background Art

[0002] In order to maintain a good position after upper limb fracture reduction, prevent fracture re-displacement, and ensure normal healing of tissues after injury, medicine often uses external fixation methods such as splints, plaster, or a combination of splints and plaster to fix the fracture site. However, splints and plaster are not breathable and stuffy, which may cause skin inflammation and infection. Splints and plaster have no elasticity. If they are fixed too tightly, they will compress nerves and blood vessels, causing muscle atrophy and pain. If they are fixed too loosely, the fracture site will be unstable and prone to displacement. The tightness cannot be adjusted, and it is inconvenient to use.
