Hallux Limitus and Hallux Rigidus
Hallux limitus is when there is limited movement at the hallux metatarsophalagneal (MTP) joint. This is the the joint of the big toe. Hallux rigidus is when there is absence of movement at the hallux MTP joint.
The causes that contribute to the development of these conditions include
- Degenerative joint arthritis due to cartilage damage
- Football players and other sports players who repetitively kick a ball.
- Pes planus (flat feet) as the feet pronates and leads to excessive joint wear
- Sepsis, inflammatory arthritis or excessive weight transfer
Treatment for the pain include anti-inflammatory drugs, rest and elevation of the foot. Steroid injections are used only for short term pain relief. Rigid insoles restricting the joint movement lessen the pain. A rocker bar can be fitted on the the shoe to offload the metatarsal head. Surgery can be considered if none of the above help.
