How long it takes to heal a minor bone fracture in the hand joint depends on the location of the fracture, the depth of the fracture, and the length of the fracture. The fracture will cause damage to the surrounding tissues, which will lead to the bleeding of tiny blood vessels and the formation of a blood crust in the fractured area. The blood crust contains more osteogenic factors, which will promote the proliferation of osteoclasts and the healing of the fracture, and the blood crust will gradually mechanize after about two weeks to form a fibrous cartilage crust. After that, the cartilage scabs gradually become old and form bone tissue, and it takes about one month until then. After that, the healing process basically focuses on shaping the fractured part of the bone, and it takes about one year for the fractured part of the bone to be shaped to its pre-fractured state. There are some special circumstances that may prolong the healing time of a fracture, such as smoking, drinking, irregular work schedule, staying up late, or trauma or external forces that may cause a recurrence of the fracture or result in a more serious fracture.
