Whether or not a broken thumb joint will return to normal depends on the severity of the patient’s break. For example, if the fracture is not very severe, normal function may usually be restored with treatment. However, a comminuted fracture or nerve damage may not allow a full return to normal function. If the thumb joint fracture is not very serious and the misaligned fracture is treated aggressively, and functional exercises are adhered to at a later stage. Generally the fracture will heal and the joint mobility will gradually return to normal. However, if the patient’s thumb has a comminuted fracture or tendon or nerve rupture, even if the patient is actively treated, fascial contracture and other conditions may occur, and the probability of a complete return to normal is generally very small. When thumb joint fracture occurs, it is recommended to consult a doctor in time, cooperate with the doctor for active treatment, and actively carry out functional exercises at a later stage, which can promote the recovery of thumb function.
