Hallux rigidus is arthritis of the joint at the base of the big toe. It is the most common arthritic condition in the foot and typically causes pain and stiffness when pushing off during walking.
Hallux rigidus is osteoarthritis of the first metatarsophalangeal joint at the base of the big toe. Because this joint must bend with every step, even modest stiffness can make walking, running and pushing off uncomfortable.
Assessment focuses on how much movement remains at the joint, whether pain is coming from the bone spur on top of the joint or from within the joint itself, and whether foot alignment is contributing. A weight-bearing X-ray helps determine the stage. Other causes of forefoot pain, including gout, sesamoid problems and bunion-related pain, need to be considered when the pattern is unclear.
First-line care is usually footwear modification and offloading — a roomy toe box, a stiff or rocker-bottom sole, or a rigid forefoot insert — alongside activity adjustment and simple analgesia. Podiatry input is often useful at this stage. Where symptoms persist despite appropriate non-surgical care, or where joint changes are advanced, referral to an orthopaedic foot and ankle surgeon is appropriate to discuss surgical options.
