Isolated rounded bones near the medial humeral epicondyle and the so called cubital patella are traumatic in origin. They are the result of the separation of the epiphyseal ossification center in early childhood, without subsequent absorption and with independent further development. The theory of congenital origin is not convincing. Recent trauma has nothing to do with causing these accessory bones. There is no loss of function of the joint.
