What characterizes a Mallet Toe?

• A. Flexion deformity of PIP with no fixed deformity
• B. Flexion deformity of DIP with no fixed deformity of PIP or MTP
• C. Fixed extension of the MTP joint
• D. Flexion contracture of the DIP

Answer: (B)

A Mallet Toe is primarily characterized by a flexion deformity at the distal interphalangeal (DIP) joint, which can occur without a fixed deformity at the proximal interphalangeal (PIP) joint or the metatarsophalangeal (MTP) joint. This condition results in the toe being unable to extend at the DIP joint, causing the tip of the toe to point downwards. It is important to note that the PIP and MTP joints remain either straight or able to move freely, without fixation in flexion or extension. The presence of a flexion deformity specifically at the DIP joint distinguishes Mallet Toe from other toe deformities. In different conditions like Hammertoe, for example, the PIP joint is often involved, and the deformities typically present differently. Understanding these distinctions is essential for accurate diagnosis and treatment planning in orthopedic care.
