What is a Bunion?What is a Bunion?

A bunion is a painful bulging bone protrusion of the metatarsophalangeal joint, also known as the base of your big toe. Traditionally, bunions are inherited and painfully worsen over time, especially in bunion sufferers who spend much of their day on their feet or wear improperly fitting shoes.

This bony protrusion, also known as the bursal sac, consists of swollen bone from bone calcification, inflamed tissue, and reddened skin. Friction and pressure from bunion neglect such as improperly fitting shoes can leave the skin near the bunion dry and flakey.

Proactive bunion treatment and orthotics can slow the worsening of bunion deformity as well as bring relief to your aching bunions without surgery. For more information on bunion relief and bunion treatment, check out my previous blog post: Non Surgical Bunion Treatment.

What is Hallux Valgus?

Hallux Valgus is the medical term for a bunion deformity, where the latin term “hallux” refers to the big toe and latin term “valgus” refers to an unnatural deviation of the big toe. Hallux Valgus is divided into two bunion deformity categories: positional bunions and structural bunions.

Positional Bunion (mild bunion deformity)
A positional bunion is present when the big toe leans slightly towards the other toes. Accordingly, the base of the big toe will slightly protrude out from the inside of the foot at the metatarsophalangeal joint. Even a slight deviation of the big toe can produce a bunion, which is commonly accompanied by soreness, bruising, and swelling.

Structural Bunion (severe bunion deformity)
A structural bunion is present when base of the big toe is severely out of place, creating a significantly larger angle between the joints of the big toe and second toe than seen in a positional bunion.
