Hallux rigidus or stiff big toe is haklux arthritis and stiffness due to bone spurs that affects the MTP joint at the base of the hallux big toe.

Hallux flexus was initially described by Davies-Colley [1] in as a plantar flexed posture of phalanx relative to the metatarsal head. About the same time, Cotterill first used the term hallux rigidus. Although the condition is degenerative, it can occur in patients who are relatively young, particularly active sports people who have at some time suffered trauma to the joint turf toe.

This condition, which occurs in adolescents and adults, can be associated with previous trauma. The true cause is not known. Most commonly, hallux rigidus is thought to be caused by wear and tear of the halux metatarsophalangeal joint.

Physical therapy programs may be recommended, although there is very limited evidence that they provide benefit for reducing pain and improving function of the joint. In some cases, surgery is the only way to eliminate or reduce pain.


There are several types of surgery for treatment of hallux rigidus. The type of surgery is based on the stage of hallux rigidus. Stage 1 hallux rigidus involves some loss of range of motion of the big toe joint or first MTP joint and is often hallkx conservatively with prescription foot orthotics.

Stage 2 hallux rigidus involves greater loss of range of motion and cartilage and may be treated via cheilectomy in which the metatarsal head is fexus and bone spurs reduced.

Stage 3 hallux rigidus often involves significant cartilage loss and may be treated by an osteotomy in which cartilage on the first metatarsal head is repositioned, possibly coupled with a hemi-implant in which the base of the proximal hallhx base of the big toe is resurfaced. Stage 4 hallux rigidus, also known as end stage hallux rigidus involves severe loss of range of motion of the big toe joint and cartilage loss.

Stage 4 hallux rigidus may be treated via fusion of the joint arthrodesis or implant arthroplasty in which both sides of the joint are resurfaced or a hinged implant is used. Fusion of the joint is often viewed as more definitive flexuw may lead to significant alteration of gait causing postural symptomatology.

The implants termed “two part unconstrained” implants in which a “ball” type device is placed on the first metatarsal head and “socket” portion on the base of the big toe do not have a good long term track record. The hinged implants have been in existence since the s, have been continually improved and have the best record of improving long term function. From Wikipedia, the free encyclopedia.
