What Is Hallux Limitus /Rigidus?
Hallux Limitus/ Rigidus commonly refers to osteoarthritis of the big toe, the pain and inflammation of which can gradually, over time, restrict movement.
The degenerative changes can be mild to severe and affects adults and adolescents. There may or may not be a history of trauma.
What Causes Hallux Limitus / Rigidus ?
It is thought to relate to ‘wear and tear’ of the joint through acute, or more usually, chronic repetitive injury. Symptoms result from a degeneration of the big toe joint and are characterised by loss of cartilage, osteophytes and altered joint mechanics. As with any degeneration a combination of overuse, injury or abnormal joint mechanics may combine to produce stresses and damage to articular cartilage.
Treatment approaches can be used for various stages of disease. These include:
- Analgesics including non-steroidal anti-inflammatory drugs.
- Orthotics limiting/ restricting dorsiflexion
- Footwear modifications
- Modification of activities (avoid kneeling/squatting for example)
- Surgery in severe cases
