Bunion (Hallux Valgus)

Q: Will my bunion come back after surgery?

Recurrence rates are 5–15% and depend on procedure selection, underlying foot structure, and footwear habits post-operatively. Proper procedure matching (e.g., Lapidus for hypermobility) and wearing appropriate shoes after surgery significantly reduce recurrence risk.

Q: Do I need surgery if my bunion doesn't hurt?

No. Surgery is indicated for pain that fails conservative management, not for cosmetic correction. Prophylactic surgery on painless bunions is not recommended.

Q: What is minimally invasive bunion surgery?

Modern MIS bunion techniques use small (2–4 mm) incisions and specialized burrs to perform the same bone cuts as open surgery. Fluoroscopy (real-time X-ray) guides the surgeon. Evidence supports equivalent or better outcomes with less swelling and faster return to activity.

Q: Can orthotics stop my bunion from getting worse?

Orthotics reduce the mechanical forces that worsen deformity and can slow progression, especially in patients with flatfoot or first-ray hypermobility. They do not reverse an existing deformity.

Q: How long after bunion surgery will I be able to walk normally and wear regular shoes?

Most patients are walking in a protective surgical boot within one to two weeks of bunion surgery, though the type of procedure influences the exact timeline. Swelling in the foot often persists for three to six months, so regular shoes — particularly narrower styles — may not be comfortable until that point. Return to low-impact activity such as walking typically occurs by six to eight weeks, while higher-impact sports may take three to four months. Your MOS surgeon will monitor bone healing with X-rays and clear you for activity milestones based on how well the correction is consolidating.

A bunion — clinically termed hallux valgus — is the most common deformity of the forefoot, affecting an estimated 23% of adults and up to 35% of those over age 65. It is far more prevalent in women, largely owing to footwear habits. The condition is progressive: a small medial bump in the 20s can become a painful, arthritic deformity that limits walking by the 50s. At Maryland Orthopedic Specialists, we offer the full continuum of care — from footwear counseling and custom orthotics to the latest minimally invasive surgical techniques — with the goal of relieving pain while preserving the foot's structure and function for decades to come.

What is bunion (hallux valgus)?

A bunion (hallux valgus) is a progressive deformity of the big toe, where the toe drifts toward the others and a bony bump forms on the inner edge of the foot at its base. It can cause pain, swelling, and difficulty with footwear, and tends to worsen over time.

Hallux valgus describes a complex three-dimensional deformity of the first ray:

The first metatarsal drifts medially (varus), causing a bony prominence (the "bunion") on the inner border of the foot at the metatarsophalangeal (MTP) joint
The hallux (great toe) deviates laterally (valgus), sometimes crossing over or under the second toe
The sesamoid bones beneath the 1st MTP joint shift laterally out of their groove, contributing to further instability

Radiographic measurement on weight-bearing foot X-rays quantifies the deformity:

Hallux Valgus Angle (HVA): Angle between the 1st metatarsal and the hallux proximal phalanx. Normal <15°; mild deformity 15–20°; moderate 20–40°; severe >40°.
Intermetatarsal Angle (IMA): Angle between the 1st and 2nd metatarsals. Normal <9°; increased IMA reflects hypermobility or instability of the 1st tarsometatarsal (TMT) joint — a key factor in surgical planning.

Contributing Factors

Genetic predisposition (familial in 70%+ of cases), female sex (10:1 ratio), flatfoot, ligamentous laxity, pointed-toe or high-heeled footwear (which worsens but does not solely cause deformity), and first-ray hypermobility. Bunions do not arise from calcium deposits or walking too much.

Treatment options

Conservative care manages bunion pain but does not correct the deformity — surgery is the only way to realign the toe.

Non-Operative Management

Wide toe box shoes with a soft upper and low heel are the single most effective conservative measure. Bunion pads and toe spacers cushion the bump and keep the toe more comfortable during daily activity. Custom orthotics reduce pressure on the joint and may slow progression in some patients.

Surgical Procedure

Bunion Surgery (Hallux Valgus Correction)

Surgical correction of hallux valgus deformity using technique matched to severity — Chevron osteotomy for mild deformity through Lapidus fusion at the first tarsometatarsal joint for moderate-to-severe or hypermobile cases.
