Claw toe, also known as the malalignment of the toes, refers to an abnormality where the metatarsophalangeal joint is hyper-extended, and the proximal interphalangeal joint is hyper-flexed. From the side, it looks like an inverted VType, in general, the second toe is more prone to occur than other toes, with women more likely to be affected than men. This is often related to shoe-wearing habits and the high incidence of hallux valgus. 

Claw toe can be divided into two types:

●Soft Clubbing Toe: It is called soft clubbing toe because the interphalangeal joint of the toe is still mobile. This type is relatively rare, as it can be diagnosed and treated early.

●Hallux Rigidus: The incidence of hallux rigidus is relatively high. The traumatogenic arthritis in the interphalangeal joint is severe, with narrowing or even disappearance of the joint space, stiffness and fixation of the joint, which prevents movement. Due to the fixation of the joint, the surrounding muscles and tendons contract, further exacerbating the deformity. Surgical treatment is usually required. 

Main Clinical Symptoms:

●Due to the compression and friction of the shoes, there is redness, swelling, and pain in the deformed and contracted joints.

●If left untreated for a long time, calluses can form at the obvious deformity of the joints.

●Joint stiffness, unable to move, pain may occur when passively moving the joint.

●Due to the flexion deformity of the metatarsal bones causing a low position of the metatarsal head, pain occurs at the joint of the metatarsal head after long-term friction.

The formation mechanism of hammertoe:

The formation of hammertoe is caused by an imbalance in the strength of extensor and flexor muscles. This imbalance of muscle force acts on the interphalangeal joint, which is subjected to compression deformation. This leads to joint deformation and an abnormal position of the joint, which is subjected to long-term pressure, forming traumatic arthritis. In severe cases, the joint space narrows, leading to an irreversible deformity.

Inheritance, Trauma, Cardiomyopathy4It can also cause clubfoot deformity. In addition, wearing shoes that are too tight can induce clubfoot deformity.
