Foot Deformity Secondary to Inflammatory Arthritis
The big toe develops a large bunion deformity including severe pain in the joint. The lesser toes develop clawing and prominence of the metatarsal heads leading to metatarsalgia. The lesser joints can sublux leading to further deformity.
Treatment: If conservative treatment in the form of accommodative footwear does not work the surgery is likely to involve fusion of the big toe and excision of the lesser metatarsal heads.
Midfoot and Hindfoot
These joints usually become painful due to inflammation. Image guided injections can be attempted but if stop working then the joints are likely to need fusion.
