The hammer finger

Description of the pathology, definition and symptoms.

The hammer finger is a deformity of the foot characterized by a hyperflexion of the proximal interfalange joint that takes on a characteristic "zeta" form. It mostly affects the second and third finger of the foot, but it can also affect the fourth finger.

The hammer finger is hypertensive on the first phalanx and flex at the level of the second. Deformity can be fixed or flexible depending on the degree of joint rigidity that develops over time. In flexible deformity it is still possible to bring the finger passively back to its anatomical position,What not possible when deformity becomes fixed due to the rigidity established. This pathology is often associated with that of the Alluce Valgo.

The anomalous flexion of the proximal interfalange of the fingers, which takes on the appearance of a hammer, leads to the formation of a dock, On the upper part of the fingers, with which a borsite is often associated which can also become very painful. The latter is an inflammation of the serous bag, a sort of bearing that contains liquid with the shock absorber function between tendons and muscles and tends to ulcers in contact with the shoe, especially if narrow or too rigid. In these cases, the patient has difficulty carrying out movements of the affected finger and accuses pain in moving the foot and in the walking phase. Over time the hammer finger tends to worsen and stiffen due to the retraction of the joint capsules.

Conservative therapy

In the conservative field, the Orthopedic Specialist can suggest the type of footwear to be worn and the use of specific orthoses which, improving the position of the finger, contribute to reducing the annoyance generated by the friction with the shoe, generally elastic and high in the compromised area , to avoid contact as much as possible.
