Hallux Rigidus: A Complete Guide

Hallux rigidus is a particularly common condition that affects the joint between the big toe and the rest of the foot, limiting movement, especially during dorsiflexion, and causing severe pain in the big toe, which often extends to the other toes and the lesser metatarsals. Those suffering from this condition have difficulty bending their big toe, and the pain often intensifies during physical activity or after prolonged walking.

This form of osteoarthritis develops due to progressive cartilage deterioration and is the leading cause of foot surgery in men. It is a congenital anatomical characteristic that can significantly impact quality of life from a young age, limiting mobility and causing difficulty with even the simplest daily tasks, such as walking or putting on shoes. Furthermore, joint pain and stiffness tend to worsen with movement.

What are the symptoms and causes of hallux rigidus?

The elevation of the first metatarsal which limits and sometimes even prevents movement between the metatarsal itself and the proximal phalanx of the big toe.

Hallux rigidus is usually caused by osteoarthritis, a degeneration of the cartilage lining the big toe joint. Some individuals may be predisposed to developing this condition due to genetic factors.

Toe stiffness compromises propulsion during walking. This, in turn, causes overloading of the lesser metatarsals, which are forced to take over the work not performed by the big toe, eventually becoming inflamed and causing pain. Our body tries, in some ways, to "defend" itself from this problem by developing plantar calluses on the metatarsals.

Other possible causes of hallux rigidus include previous injuries to the big toe, such as fractures or sprains, which can accelerate the degeneration of the joint, or pathologies such as rheumatoid arthritis that can contribute to the onset of hallux rigidus.

In some cases, symptoms of hallux rigidus include redness or swelling of the affected area, which causes difficulty wearing shoes, especially those with narrow toes or high heels.

Treatments for hallux rigidus

Treatment of hallux rigidus depends on the severity of the condition. In early cases, pain can be reduced and function improved with conservative measures:

• The use of appropriate footwear: Comfortable shoes with good support can relieve pressure on the joint. It's essential to choose a model that supports the push-off phase of your step.
• Taking anti-inflammatory drugs to reduce pain and inflammation.
• Physiotherapy and specific exercises that help improve joint mobility and strength.

However, conservative therapies often fail to resolve the symptoms, but at most, alleviate them. In these cases, surgery may be considered to correct the bone anatomy.

Corrective osteotomy involves the removal of portions of bone to correct the anatomy of the foot and improve joint alignment. Arthrodesis , on the other hand, is decidedly more invasive, as with this type of procedure, the bones of the big toe are fused together to eliminate movement and reduce pain.

In both cases, recovery times are similar. For both, it's essential to follow a physiotherapy program to restore full mobility.
