Hallux limitus is a degenerative condition that affects the joint at the base of the big toe, also known as the first metatarsophalangeal (MTP) joint. It is characterized by stiffness and limited range of motion in the big toe, which can make it difficult to walk or participate in activities that require pushing off with the toes.

In hallux limitus, the cartilage in the MTP joint gradually wears away, leading to bone-on-bone contact and the formation of bone spurs. This can cause pain, swelling, and stiffness in the joint. The condition is often caused by structural abnormalities, such as a long or elevated first metatarsal bone, or biomechanical issues that put excessive pressure on the MTP joint.

Hallux limitus can be treated with conservative measures such as shoe modifications, orthotics, physical therapy, and pain-relieving medications. In more severe cases, surgery may be necessary to relieve symptoms and restore mobility to the joint.

Hallux Valgus is a medical condition that affects the foot, specifically the big toe joint. It is characterized by the deviation of the big toe (hallux) towards the second toe, resulting in a prominent bump on the inner side of the foot at the base of the big toe. This bump is actually the metatarsal head of the first bone in the foot that becomes exposed due to the angulation.

The deformity can lead to pain, stiffness, and difficulty wearing shoes. In severe cases, it can also cause secondary arthritis in the joint. Hallux Valgus is more common in women than men and can be caused by genetic factors, foot shape, or ill-fitting shoes that put pressure on the big toe joint.

"Hallux" is a medical term that refers to the big toe or great toe, which is the first digit of the human foot. It is derived from Latin, where "hallus" means "big toe." In some contexts, specific pathologies or conditions related to the big toe may also be referred to as hallux issues, such as hallux valgus (a common foot deformity where the big toe drifts toward the second toe) or hallux rigidus (a form of degenerative arthritis that affects the big toe joint).

Hallux rigidus is a degenerative arthritis condition that affects the joint at the base of the big toe, also known as the first metatarsophalangeal (MTP) joint. This condition is characterized by stiffness and limited motion in the big toe joint, leading to difficulty with walking and pushing off during the gait cycle.

The degenerative changes in the joint can cause bone spurs, or osteophytes, to form on the top of the joint, which can further limit motion and cause pain. The condition may also result in decreased shock absorption and increased stress on other parts of the foot, potentially leading to additional foot problems.

Hallux rigidus is typically caused by wear and tear on the joint over time, although it can also be associated with trauma or injury to the big toe joint. Treatment options for hallux rigidus may include pain relief medications, physical therapy, shoe modifications, orthotics, or in severe cases, surgery.
