What Is Hallux Rigidus?
Hallux rigidus — literally meaning ‘stiff big toe’ — is osteoarthritis of the first metatarsophalangeal (MTP) joint, the joint at the base of the big toe. It is the most common arthritic condition of the foot and the second most common condition affecting the big toe after hallux valgus (bunions). In a healthy joint, smooth cartilage allows the big toe to bend upwards by around 65–75° during the push-off phase of walking and running.
In hallux rigidus, this cartilage progressively thins and wears away. Bone spurs (dorsal osteophytes) form on the top of the joint, blocking upward movement of the toe. The result is pain, stiffness, swelling and a visible bump on top of the big toe — symptoms that can dramatically limit walking, running and sporting activity. Because the big toe absorbs around 40–60% of body weight during push-off, untreated big toe arthritis often forces patients to alter their gait, which can lead to secondary problems in the lesser toes, midfoot, knee, hip and lower back.
Specialist assessment by a Consultant Foot & Ankle Surgeon — such as Mr Matthew Welck in London — gives patients access to the widest range of modern treatments, including joint-preserving options and joint sacrificing options such as replacement and fusion.
