What Is Hallux Rigidus?

Hallux rigidus, also known as great toe arthritis, is a disorder of the joint located at the base of the big toe. It causes pain and stiffness in the joint, and with time it gets increasingly harder to bend the toe. Hallux rigidus is actually a form of degenerative arthritis.

Great Toe ArthritisThis disorder can be very troubling and even disabling, since we use the big toe whenever we walk, stoop down, climb up or even stand.

Many patients confuse hallux rigidus with a bunion, which affects the same joint, but they are very different conditions requiring different treatment. Because hallux rigidus is a progressive condition, the toe’s motion decreases as time goes on.

In its earlier stage, when motion of the big toe is only somewhat limited, the condition is called “hallux limitus.” But as the problem advances, the toe’s range of motion gradually decreases until it potentially reaches the end stage of “rigidus,” in which the big toe becomes stiff, or what is sometimes called a “frozen joint.”

Causes of Hallux Rigidus

Common causes of hallux rigidus are faulty function (biomechanics) and structural abnormalities of the foot that can lead to osteoarthritis in the big toe joint. This type of arthritis – the kind that results from wear and tear – often develops in people who have defects that change the way their foot and big toe functions. For example, those with fallen arches or excessive pronation (rolling in) of the ankles are susceptible to developing hallux rigidus.

Hallux RigidusIn some people, hallux rigidus runs in the family and is a result of inheriting a foot type that is prone to developing this condition. In other cases, it is associated with overuse – especially among people engaged in activities or jobs that increase the stress on the big toe, such as workers who often have to stoop or squat.

Hallux rigidus can also result from an injury, such as stubbing your toe. Or it may be caused by inflammatory diseases such as rheumatoid arthritis or gout. Dr. Butler can determine the cause of your hallux rigidus and recommend the best treatment.
