What is bunion (hallux valgus)?
<\/span><\/h2>\n<\/header>\n
The bunion<\/strong> (hallux valgus) is one of the most common foot deformities. It is characterized by the lateral deviation of the big toe towards the other toes and by the prominence of the bone on the inner aspect of the first metatarsal. Although it is often perceived as an aesthetic problem, it is actually a functional disorder that can cause pain, chronic inflammation and difficulty walking. <\/p>\n

From an anatomical point of view, hallux valgus is the result of an instability of the first metatarsophalangeal joint<\/strong>. The metatarsal bone is displaced inward, while the proximal phalanx of the first toe is deflected outward. This creates a bony protrusion that rubs against the shoe, causing corns, bursitis and overloading of the adjacent toes. <\/p>\n

It is important to emphasize that it is not “new bone” that grows, but a progressive bone misalignment<\/strong>. The earlier it is detected, the more options there are to control it and slow its progression. <\/p>\n<\/section>\n

Symptoms, causes and diagnosis<\/h2>\n

Initial symptoms are usually mild, such as discomfort when wearing narrow shoes. Over time, the pain increases and is accompanied by recurrent swelling, difficulty in finding suitable footwear and visible deformity. In advanced stages, the hallux may mount on the second toe, resulting in claw or hammertoes. <\/p>\n
