Foot

What It Is

Hallux osteoarthritis means degenerative ("wear and tear") arthritis of the big toe joint. The big toe joint is the joint in the foot most commonly affected by osteoarthritis (Roddy and Menz, 2018). This common condition can cause substantial pain and disability. A painful big toe joint with reduced movement can change the way you walk: some people walk on the outside of the foot to avoid pain in the big toe, which can lead to pain on the outer side of the foot (AAOS, n.d.; Lam et al., 2017).

Arthritis of the big toe joint may be the result of simple wear and tear over many years, or of repeated injuries to the big toe that damage the joint cartilage over time (AAOS, n.d.). Occasionally people remember a particular incident that they believe started the joint pain. Poor foot alignment, such as flat feet or a bunion, and genetic factors can also play a part (AAOS, n.d.).

Hallux osteoarthritis typically causes pain in the big toe joint, especially when walking, along with stiffness and reduced movement (AAOS, n.d.; Norfolk and Norwich University Hospitals NHS Foundation Trust, 2023). The joint can look swollen or thickened, a bump may develop on top of the joint, and walking can be painful. The person may limp, or walk on the outside of the foot to protect the big toe (AAOS, n.d.).

Hallux Osteoarthritis Anatomy

The joint at the base of the big toe is called the metatarsophalangeal (MTP) joint. Just like any other joint in the body, the ends of the bones are covered with articular cartilage, a smooth, slippery covering. If this cartilage is damaged, it can begin to wear away until bone is rubbing against bone (AAOS, n.d.).

When this happens, the body lays down extra bone, forming new bone called osteophytes or bone spurs. These usually develop on the top of the joint, where they can pinch the surrounding soft tissues and restrict the toe’s ability to bend upwards when you walk (AAOS, n.d.; Norfolk and Norwich University Hospitals NHS Foundation Trust, 2023).
