There are more reasons for hand swelling, such as fracture causing soft tissue vascular damage to the skin muscle, which can affect blood return to the arm leading to local edema, fracture causing muscle or soft tissue contusions after necrosis, local pressure formation leading to swelling can also occur. Hand swelling requires symptomatic treatment, for example, by elevating the affected limb above the heart level, or early icing to reduce swelling. Ice is usually applied within 24-48 hours after the injury, and it is recommended to apply ice within 48 hours, which not only reduces swelling but also relieves the patient’s pain. It is also possible to reduce inflammation and analgesia by auxiliary drugs, such as blood-activating drugs, Chinese medicine or western medicine, etc. Since early swelling is the exudation period, taking blood-activating drugs will aggravate the hematoma, so it needs to be taken 48 hours after the injury. Local braking can also be applied, and external fixation braking by brace or plaster will help to reduce the swelling after stabilization.
