(hallux limitus; hallux rigidis)
Arthritis of the big toe usually causes pain, a loss of movement in the metatarsophalangeal joint (MTPJ) and often a lump on the top of the toe that may rub on shoes.
It is a common condition, especially in people that have played a lot of sport. It may often occur in both big toes but one is usually worse than the other.
Treatment depends on symptoms and the severity of the arthritis within the joint.
Non-surgical treatments involve activity-modification; pain-kiling and anti-inflammatory tablets; and shoewear alterations.
Injections into the joint may help in some situations.
Surgical options usually involve either a cheilectomy (clean out of the joint) or a joint fusion (arthrodesis or stiffening). The decision is made on the degree of arthritis in the joint and the movement that is present.
A very stiff, painful joint will benefit from a fusion. This permenantly stiffens the joint in order to relieve the pain. The joint is held in place with screws &/or small plate.
If the joint is painful but has a reasonable range of movement then a cheilectomy takes away the bony lump, decreases the pain and preserves motion.
Joint replacements are available for the MTPJ but the results at present are variable.
