Hand fracture swelling is divided into early edema and rehabilitation edema. Early edema usually subsides in about two weeks, and rehabilitation edema may take 3-6 months or even longer. 1. Early edema: Early edema generally refers to the local edema symptoms that appear after the patient is injured, due to the local soft tissue damage caused by the fracture, resulting in vascular rupture or increased vascular permeability, tissue fluid exudation caused by increased swelling. Most of the patients after physical, drug or surgical treatment, edema can generally subside in about two weeks. 2. Rehabilitation edema: after conservative or surgical treatment, a longer recovery period is needed, and local edema may occur during the recovery period; at the same time, due to the need for rehabilitation training during the recovery period, which may lead to an increase in tissue exudation and recurrence of edema, but most of the patients’ edema symptoms will gradually disappear in 3-6 months. If the symptoms of hand fracture swelling are not relieved, or accompanied by other symptoms, the patient should go to the hospital in time, to identify the cause and then give targeted treatment.
