Which toe condition is associated with rheumatoid arthritis and neurological disorders?

• A. Mallet Toe
• B. Claw Toe
• C. Hammer Toe
• D. Flatfoot

Answer: (B)

Claw toe is a condition characterized by hyperflexion of the distal interphalangeal (DIP) joint and hyperextension of the proximal interphalangeal (PIP) joint of the toes. It is notably associated with conditions like rheumatoid arthritis and certain neurological disorders. In rheumatoid arthritis, the inflammation and deformities caused by the disease can lead to muscle imbalances and instability of the small joints of the toes, resulting in the characteristic clawing of the toes. Neurological conditions can also result in claw toe as they may affect motor function or sensation, leading to changes in the foot's mechanics and positioning over time.

Mallet toe and hammer toe, while also involving deformities of the toe, are less frequently connected with systemic diseases such as rheumatoid arthritis or neurological disorders. Mallet toe typically refers to a flexion deformity of the distal joint, while hammer toe involves a flexion deformity of the PIP joint. Both conditions are primarily related to mechanical stresses or imbalances rather than direct connections to systemic inflammatory processes or neurological issues.

Flatfoot, on the other hand, refers to a condition where the arch of the foot collapses, leading to the entire foot coming in contact with the ground. This condition is not specifically related
