What It Is

Metatarsophalangeal (MTP) joint osteoarthritis is "wear and tear" arthritis in the joints where the toes meet the foot. It most often affects the big toe joint, where it is also called hallux rigidus, or stiff big toe (AAOS, n.d.; Norfolk and Norwich University Hospitals NHS Foundation Trust, 2023). It happens when the smooth cartilage covering the ends of the bones in the joint wears away, and bony growths (bone spurs) can form on top of the joint. These stop the toe bending as much as it needs to and can cause pain (AAOS, n.d.; Norfolk and Norwich University Hospitals NHS Foundation Trust, 2023). It may be caused by simple wear and tear or by repeated injury to the joint (AAOS, n.d.).

Osteoarthritis is the most common type of arthritis in the UK (NHS, 2023a). It can affect any joint and causes pain and stiffness, and it becomes more likely as you get older (NHS, 2023a). Even though there isn't a cure for osteoarthritis, it does not necessarily get worse over time, and there are a number of treatments to help relieve the symptoms (NHS, 2023b). It is worth seeking help at an early stage. With treatment, most people with osteoarthritis are able to manage their pain and remain active, and surgery is only needed in a small number of cases (NHS, 2023b).

Metatarsophalangeal Joint Osteoarthritis Anatomy

In each foot, you have five metatarsal bones running from the middle of the foot towards the toes. The metatarsophalangeal (MTP) joints are where the rounded ends (heads) of the metatarsals meet the toe bones (phalanges), at the ball of the foot. The big toe joint bends every time you push off when walking.

When this joint is stiff and painful, you may have pain on the top of the joint when walking, difficulty pushing off, swelling or thickening around the joint, and you may find yourself walking on the outside of your foot to avoid the pain (AAOS, n.d.).
