Short thumbs are common in the following cases: First, due to individual developmental differences, some people have longer fingers and some have shorter fingers, short thumbs are generally symmetrical and do not produce obvious dysfunction or deformity, and have no obvious effect on daily hand function, so no special treatment is needed in this case. Second, during the growth and development of one side of the thumb is injured, resulting in epiphyseal injury, the bone injury will affect the development of the thumb, resulting in a very short thumb, in this case there will often be bilateral thumb asymmetry, the injured side of the thumb will appear short and thick symptoms, may also produce mild deformity, etc., in this case, if in adulthood there is no dysfunction, the impact on hand function is not significant. In this case, if there is no functional impairment in adulthood, the impact on the function of the hand is not significant and no special treatment is required. In this case, if there is no dysfunction in adulthood, there is no need for special treatment. If there is dysfunction, the deformity is obvious and the impact on the function of the hand is greater, the corresponding surgical treatment can be performed to correct the deformity. Thirdly, patients with congenital abnormalities such as short thumb deformity often have significant thumb dysfunction, and generally require physical therapy, conservative treatment, functional training, and even surgical reconstruction.
