The fixation method of humeral fracture is splint fixation. Prepare two splints and put them in front of and behind the upper arm respectively, and fix them with a triangle towel or bandage. After fixation, the elbow joint should be bent 90 degrees, and the shoulder joint should not move. The forearm should be hung on the chest, and the upper arm should be close to the side of the limbs. The upper arm and torso should be bound and fixed with bandages or triangular towels. At the same time, bend the elbow 90 degrees and fix it with forearm sling. This is the fixation method of humeral fracture of upper arm.

If it is a fracture of ulna and radius, fix the dorsal and palmar sides with splint, then fix it with triangle belt or bandage, bend the elbow joint 90 degrees and lift it with forearm sling. If there is no splint, roll up the lower corner of the clothes and tie it with the corner line of the clothes to form a fixed sling, so that the forearm is close to the chest.

Arm fracture belongs to upper limb fracture, which usually includes humeral fracture and forearm ulnar and radial fracture. The clinical symptoms of arm fracture are mainly local swelling, severe pain and dyskinesia. In addition, the fracture will form a pseudojoint.

Because there are many nerves and blood vessels in the arm around the bone, violent injury can lead to nerve and blood vessel damage. If nerves and blood vessels are punctured by broken ends, you will not feel the pulse of the distal artery or the abnormal movement of your thumb and numbness of your hands. Therefore, on the one hand, the symptoms of arm fracture are their own symptoms, on the other hand, they are the corresponding symptoms of nerve and blood vessel damage.
