Brace fixation of humerus fractures is indicated for humerus fractures that do not cause neurovascular compromise. The fracture is externally immobilized with a brace after manual reduction. For neurovascular injuries or open humeral fractures, surgical plate fixation followed by external fixation with a brace is required. Brace fixation involves the selection of an appropriately sized splint, which is usually malleable and X-ray permeable. The method of fixation is to choose a suitable size of brace that can fit well with the affected limb after the fracture site has been reset by manipulation or traction, and then fix the brace to the affected limb with a bandage for a period of 4 to 6 weeks. Remove it when it expires. When a humerus fracture occurs, please go to the hospital in time to avoid delay.
