Hallux valgus: can surgery be avoided?

Hallux valgus, commonly known as a bunion, is a deformity of the big toe that affects millions of people, primarily women. Faced with this condition, many patients wonder whether a bunion orthotic can help them avoid surgery. The answer depends on the stage of the deformity and the severity of symptoms, but conservative approaches deliver encouraging results in many cases.

Understanding hallux valgus

Hallux valgus appears as a lateral deviation of the big toe toward the other toes, accompanied by a bony bump on the inner side of the foot. This deformity results from an imbalance between the muscular and ligamentous forces that keep the big toe aligned. Contributing factors include heredity, wearing narrow-toed, high-heeled shoes, excessive foot pronation and certain inflammatory conditions. Progression is generally slow, which provides an important window for conservative intervention.

The role of the foot orthotic

A custom bunion orthotic plays a fundamental role in the conservative management of this condition. The orthotic cannot reverse a bony deformity that is already present, but it can considerably slow its progression and relieve pain. By correcting excessive pronation, a major aggravating factor, the orthotic reduces the forces that push the big toe outward. It also redistributes plantar pressures to offload the painful joint of the first metatarsal.

Adapted footwear

Footwear choice is decisive in managing hallux valgus. Wide-toed shoes allow the big toe to maintain a more natural alignment without lateral pressure. Combining a custom bunion orthotic with appropriate footwear is the most effective conservative strategy. Avoid pointed-toe shoes, heels higher than four centimetres and shoes that are too tight. Shoes made of soft materials that adapt to the shape of the foot are preferable.

Night splints and toe spacers

In addition to the bunion orthotic worn during the day, night-time devices can be used. Night splints hold the big toe in a corrected position during sleep, helping to stretch contracted tissues and limit progression of the deformity. Silicone toe spacers worn inside the shoe reduce friction between the toes and relieve pressure on the bump. These devices complement, rather than replace, the foot orthotic.

When does surgery become necessary?

Surgery is considered when conservative treatments can no longer control the pain or when the deformity significantly interferes with walking and daily activities. A severe hallux valgus with a large deviation angle, osteoarthritis of the metatarsophalangeal joint or associated deformities of the neighbouring toes are surgical indications. Nevertheless, many patients manage their condition effectively for years thanks to a conservative approach combining a bunion orthotic with adapted footwear.
