What is a bunion (Hallux Valgus)?

Bunions or the medically termed Hallux Valgus is a progressive deformity of the big toe resulting in widening of the forefoot and gradual dislocation of the big toe towards the second. The overlying skin maybe swollen, red and tender. Bunions are often painful and can limit what shoes you can wear

Causes of bunions:

Bunions are a common occurrence in men and women and typically start progressing in their teens. It is well agreed amongst foot specialists that a strong genetic link exists in most cases.

More than 50% of Women in the UK have bunions, therefore it is a common foot deformity. The problem often runs in families, although tight narrow shoes and high heels are often blamed.

Symptoms of bunions:

  • A bulge or bump on the outside of your big toe
  • Pain and swelling around the big toe joint
  • There may be hardened skin or a callus on the bump

Diagnosing bunions:

Our consultant surgeon, Mr Kaser Nazir, will refer for X-rays at the time of your initial consultation to determine the size and angle of your bunion deformity. This will allow him to offer the most suitable surgery to correct and align the bunion.

Surgery for bunions:

  • Scarf and akin osteotomy – the procedure can be carried out under local anaesthesia or sedation as a day case. The bunion bump is shaved down, the metatarsal cut and joint realigned. Following this screw fixations are used to keep the bone in position. A small wedge of the phalanx is removed, closed and fixed to allow the toe to heal in the aligned position. Over the first two weeks you should rest at home, during this period you can partially mobilise with the aid of crutches. Typically you can return to high impact activities between 6-8 weeks following surgery.
  • Minimally invasive bunion correction – The minimally invasive bunion correction or keyhole bunion surgery is similar to the scarf and akin osteotomy. Using an imaging intensifier (X-rays) our experienced surgeon can carry out the procedure with tiny incisions. Specialised screw fixations are used during the procedure to keep the aligned toe in position whilst it heals. We advise on two weeks rest at home whilst you partially mobilise with the aid of crutches. Typically high impact activities can start between 6-8 weeks following surgery.
  • Lapidus procedure – For more severe bunions our specialist may advise on the lapidus arthrodesis procedure. An incision is made at the top of side of your foot where the bony growth is removed. The joint near the instep (tarsometatarsal joint) is realigned and fused with fixations, typically a plate, screws and/or an implant. Over the first 2 weeks following surgery you should rest at home with your leg elevated to promote healing. After two weeks you will be transitioned in to an aircast boot for a further 4-6 weeks. Typically you will be able to return to high impact activities at 3 months following surgery.
