Which toe condition is characterized by a contracture of the MTP joint with a dorsiflexed PIP and plantarflexed MTP?

The condition characterized by a contracture of the metatarsophalangeal (MTP) joint with a dorsiflexed proximal interphalangeal (PIP) joint and a plantarflexed MTP joint is known as a hammer toe. In this deformity, the proximal phalanx is bent upwards at the MTP joint, while the middle phalanx is bent downwards at the PIP joint, creating a distinctive 'hammock' appearance. This positioning leads to pressure on the top of the toe, particularly when wearing shoes, and can result in discomfort and other complications.

Understanding the physical posture of each joint in hammer toe is essential, as it directly affects how the shoe fits and what type of support might be necessary for someone experiencing this condition. A properly fitted therapeutic shoe can help alleviate pain and prevent further complications.

Other conditions mentioned, such as claw toe and mallet toe, involve different joint articulations and foot mechanics. Claw toe typically presents with both the MTP and PIP joints bent upwards while the distal phalanx flexes downwards. Mallet toe is primarily characterized by a flexed PIP joint with the MTP being in a neutral position. A bunion involves a b
