Curly toes do not usually cause any pain for young children. As adults however, overlapping of the toes in the standing position can create pain, discomfort, and difficulty wearing proper shoes. Having short flexor tendons can also cause the bone in the toe to grow crooked over time, which can lead to a more complex surgical correction later in life. A flexor tenotomy is a simple procedure used to release the flexor tendon and correct the deformity. This allows the toe to grow straight and avoids future complications.
