Hallux Valgus or Bunion

Hallux-valgus is a distortion of the metatarsophalangeal joint of the large toe (Hallux), which deforms outwards (valgus). This deformation of the phalanx is also called Bunion.

Deformity of the metatarsophalangeal joint of the large toe or Hallux valgus may have consequences that extend to the entire foot or lower limb due to cramps or bad knee extensions, Hip or back.

To diagnose Hallux-valgus, your surgeon will need a recent X-ray to assess the degree of deformity of your joint. Enquire in advance in order to perform the most suitable examination.

Treatment options

Medical Treatment

To relieve the painful phenomena, medical treatment can include analgesics and anti-inflammatory medications, wearing an orthopedic sole and an adapted rehabilitation aimed at loosening the joint and strengthening the muscles and tendons.

Nevertheless, in the case of a deformity of your joint, medical treatment can only temporarily relieve you, if the functional gene becomes too high, a surgical consultation should be considered in order to determine the most appropriate treatment for your case.

At the Bordeaux-Merignac Sport Clinic, specialists in foot surgery practice three correction techniques for Hallux-valgus:

The chevron

Consists in correcting the deformation by repositioning the metatarsal head on its base. During consolidation, bone will be maintained by two small screws.


This technique corresponds to larger deformations that cannot be corrected by the chevron technique. The bone will be repositioned in a more anatomical axis and maintained by pins that will have to be removed 6 weeks later.

Percutaneous technique

This technique consists in performing a bone resection of the metatarsal head and creating external hinges allowing a better orientation of the articular surface. It does not entail placing of equipment but has more limited indications.
