Hallux valgus (Bunion surgery)
Hallux valgus this is a malalignment of the big toe joint which causes
the big toe to go off at an angle. As a result the big toe starts to
crowd the smaller toes. It makes the foot wider which causes footwear
fitting difficulties and also can give rise to pain within the big toe
joint and the development of painful calluses. Because the big toes
joint does not bear weight normally it can also cause pain under the
second joint which will feel like walking on a pebble.
Although this foot problem can be made worse by certain shoe types it is
an inherited condition.
A painful enlargement of the joint situated at the base of the big toe.
A bunion actually refers to the bony prominence or exostosis on the side
of the big toe.
A large sac of fluid, known as a bursa, can form over
the enlarged joint which can then become inflamed and painful.
Surgery to remove the bony prominence is called
a bunionectomy. There are over 130 different procedures recorded for
treating this condition. The Podiatric Surgeon will choose the right
procedure for the individual patient. Smaller bunions can also develop
on the outside of the little toe joint, these are known as Tailors
bunions and are also treated surgically using similar techniques.
Podiatric Surgery is the surgical treatment of the foot and its associated
structures. It is carried out by a Podiatric Surgeon, usually as a day case
procedure and often under local anaesthetic. Podiatric Surgery is available in
many NHS trusts as well as in private hospitals and clinics. A Podiatric Surgeon
manages bone, joint and soft tissue disorders.
