The numbers correspond to those in Table 1 first column. Additional angles are reviewed to determine the apex of the certain bunion deformities.


Severe deformities require a soft-tissue procedure at the first metatarsophalangeal joint and a proximal first metatarsal osteotomy. The age, health, lifestyle and activity level of the patient may also play a role in the choice of procedure. To be able to cope with all variants of hallux valgus, the surgeon needs a command of around four procedures. The principal contraindication to surgery is arterial occlusive disease e Acquired musculoskeletal deformities M20—M25, M95— Therefore, although the guideline is formulated in quite general terms, its recommendations essentially correspond to those given here.

On the basis of studies yielding evidence of levels III and IV, an algorithm was set up that distinguishes between mild, moderate, and severe deformities and lists distal, diaphyseal, and proximal osteotomies and arthrodesis of the first tarsometatarsal joint as surgical options.

Blisters may form more easily around the site of the bunion as well. Comparison of two very similar techniques; the authors recommend Chevron osteotomy because it is technically simpler. Operative technique The soft tissue covering of abcuctus foot is extremely thin, and this hampers wound healing.

Furthermore, perfusion is poorest in the foot because of its distance from the heart.

The pathogenesis of hallux valgus. The small sesamoid bones found beneath the first metatarsal which help the flexor tendon bend the big toe downwards may also become deviated over time as the first metatarsal hllux drifts away from its normal position.

The Treatment of Hallux Valgus

Trials of operative techniques have yielded inconsistent results; no one technique was superior to all others. Patients may have an enlarged bursa over the medial eminence with inflamed skin or callus. Associated lesser toe deformities, such as hammertoes, cross-over toe deformities, and transfer metatarsalgia pain, should be evaluated for as well. At the same time, osteotomies in two planes provide greater stability, because the bony contact surface is increased and the danger of dislocation reduced.

Particular care must therefore be taken when operating on the great toe. Repair of hallux valgus with a distal soft-tissue procedure and proximal metatarsal osteotomy.

As a rule rehabilitation is very functional, usually with full load bearing in a flat healing shoe. Unsourced material may be challenged and removed.
