Why Do Some Bunions Return After Surgery?

A bunion can return when the underlying structural and soft-tissue forces were not fully corrected, or when the correction was not adequately protected during healing.

"A bunion correction should not only look straight at the conclusion of surgery. It should remain stable when the foot is loaded and the toe is tested in both directions."

A bunion is not simply a piece of unwanted bone. The visible prominence develops because the first metatarsal, great toe, sesamoids, tendons, capsule, and ligaments are no longer functioning in their proper relationship. Removing the bump without sufficiently restoring the first metatarsal and the entire joint apparatus may leave the original deforming forces in place.

Restoring the First Metatarsal

A durable correction begins by moving the first metatarsal sufficiently toward its functional anatomical position. Every foot does not have to be forced into one textbook number, but the correction must restore enough alignment to rebuild the integrity of the first metatarsophalangeal joint.

Restoring the Sesamoids

Correction involves two coordinated movements: the first metatarsal is moved toward the sesamoid apparatus, and the mobilized sesamoid apparatus is restored beneath the metatarsal head. These movements counterbalance each other and help rebuild the normal joint relationship.

Neutralizing the Deforming Forces

The intrinsic and extrinsic tendons, ligaments, capsule, and plantar structures must be balanced so the great toe naturally rests in a neutral position. The extensor tendon should be centered over the longitudinal axis of the first ray.

Testing the Correction Under Load

Before closure, Dr. Moy simulates loading of the foot and observes where the great toe naturally wants to rest, gently testing toward varus and valgus. A balanced correction should remain centered rather than snapping back or drifting.

Protecting the Correction During Healing

A correction that is perfect on the operating table must still be protected. Splinting, postoperative positioning, the walking boot, activity limits, and patient compliance all help maintain alignment during healing.

Delia's Case

Delia had bunion surgery with Dr. Moy 12 years ago. She recently returned to the office for an unrelated issue, giving Dr. Moy the chance to examine that same foot more than a decade later. The correction had not recurred, and the foot still looks and functions well.

Delia's case is a useful counterpart to a revision story: it shows what the correction is designed to do when the first metatarsal, sesamoids, and soft-tissue forces are fully restored and properly protected during healing, the result can hold for over a decade, not just look good on the day of surgery.
