The deformation is well-known: the end of the first metatarsal is bent inwards (varus) while the big toe is bent outwards (valgus), creating an angle whose vertex projects into a « bunion ».
The fulcrum on the big toe is then disrupted transferring the weight to the small toes.

If the discomfort or pains are major and if medical treatments results have not been satisfactory, surgery is recommended. This operation aims at straightening the big toe and sometimes the next toes in order to put the bones back into a correct axis. The surgery usually lasts from 30 mns to one and a half hour depending on the number and types of procedures. Hospitalization usually lasts from 1 to 3 days.
