What is Hallux valgus?
Hallux valgus (hallux valgus deformity of the first toe) is the deviation of the big toe outward with simultaneous deviation of the first metatarsal bone inward. A characteristic "bunion" (exostosis) forms at the base of the toe — bursitis of the first metatarsophalangeal joint.
This is the most common deformity of the forefoot, affecting up to 23% of adults and up to 35% of people over 65 years old. Women suffer 10-15 times more often than men.
Degrees of deformity (HVA angle):
- Mild — HVA angle 15-20°, minimal symptoms
- Moderate — HVA angle 20-40°, pain when walking, difficulty with footwear
- Severe — HVA angle >40°, subluxation of the joint, osteoarthritis
Associated problems:
- Osteoarthritis of the first metatarsophalangeal joint (Hallux rigidus)
- Bursitis (inflammation of the "bunion")
- Metatarsalgia (pain in the forefoot)
- Hammertoe deformity of toes 2-3
- Calluses and corns
Facts about Hallux valgus
- ICD-10: M20.1
- Prevalence: 23% of adults
- Over 65: up to 35%
- Gender: women 10-15 times more often
- Surgeries: 200,000+/year in Germany
- Recurrence after surgery: 10-30%
Symptoms of Hallux valgus
Early signs
- Redness and swelling at the base of the big toe
- Discomfort when wearing shoes
- Slight deviation of the toe outward
- Periodic pain after prolonged walking
Progression
- Constant pain when walking
- Increase in the "bunion" (exostosis)
- Inability to wear regular shoes
- Bursitis — inflammation of the bursa
- Deformity of toes 2-3 (hammertoe)
Late stages
- Severe First Metatarsophalangeal Joint Osteoarthritis
- Joint Rigidity (Hallux Rigidus)
- Metatarsalgia — Pain in the Forefoot
- Calluses and Corns
- Gait and Posture Disturbance
Bunion (hallux valgus): treatment options and what is known about them
The treatment plan is made by the clinic doctor after an examination and a review of your images. The table shows the options usually discussed for this diagnosis and how well they have been studied.
| Option | What to expect | How well studied |
|---|---|---|
| Braces, splints, insoles | Offload and stabilise, reduce pain under load | Limited or conflicting evidence |
| Exercise therapy and physiotherapy | Reduces pain, strengthens muscles, improves function; the basis of treatment | Little data |
| Painkillers and NSAIDs | Ease pain during flare-ups; long-term use is limited by side effects | Moderate evidence |
| PRP / CGF | — | Not usually used for this diagnosis |
| Corrective osteotomy of the big toe | If conservative treatment does not help or there is an indication | When indicated — the doctor decides |
We send your request to several partner clinics. Some will suggest conservative treatment or injections, others surgery; each clinic quotes its own conditions and price. We help you compare the options.
Regenerative methods: realistic expectations
A deformity — deviation of the toe or of the leg axis — cannot be corrected with injections or exercise. Conservative measures (shoes, insoles, painkillers, exercise) reduce pain and may slow down accompanying osteoarthritis. Regenerative methods are sometimes discussed only to reduce pain from osteoarthritis, not to correct the shape.
When surgery is discussed. A deformity can only be corrected with surgery (corrective osteotomy). It is discussed when pain interferes with walking or the deformity progresses quickly.
If an injection helps, the effect usually builds up over 6–12 weeks, and the result is assessed after 2–3 months. No clinic can guarantee a result.
Good to know: diagnosis, self-help, outlook
How to tell hallux valgus from similar conditions
In hallux valgus the big toe angles towards the other toes and a bunion forms at its base, which rubs against shoes and becomes inflamed. Hallux rigidus causes pain and limited upward bending without the toe angling, and gout a sudden attack of severe pain with redness. A standing foot X-ray shows the deformity angles and the joint condition, which guide the choice of surgery.
What you can do yourself
Wear shoes with a wide toe box and low heel and use soft bunion pads. Insoles help with a flattened forefoot arch and pain under the ball of the foot. Night splints and correctors reduce discomfort but do not correct the deformity.
Outlook and timelines
Without surgery the deformity does not disappear, but many people live with it without significant pain. Surgery is discussed for persistent pain and footwear problems, not for appearance. After correction a special shoe is worn for about 6 weeks, and full recovery takes several months.
Who it is not suitable for and possible risks
Contraindications
- Active infection — at the injection site or systemic, with fever.
- Active cancer or ongoing chemotherapy.
- Blood clotting disorders or a low platelet count. Anticoagulants are discussed with the physician.
- Pregnancy and breastfeeding — the procedure is usually postponed.
- A corticosteroid injection into the same area in recent weeks.
- A complete tendon or ligament rupture with loss of function — surgical repair is usually needed.
Possible risks
- Pain and swelling at the injection site for 1–3 days.
- Bruising where blood or fat tissue is taken.
- Rarely, infection. The procedure is therefore performed under sterile conditions with ultrasound or X-ray guidance.
- The effect may be absent or smaller than expected.
If any of these apply to you, mention it in your request. The coordinator will check with the clinic physician whether treatment is possible. Contact a coordinator.
Scientific evidence
Studies of regenerative methods show mixed results. Clinic physicians rely on research including the following:
- Monto RR. Platelet-rich plasma and plantar fasciitis. Sports Med Arthrosc Rev, 2013.
- Sheth U et al. Efficacy of autologous platelet-rich plasma use for orthopaedic indications: a meta-analysis. J Bone Joint Surg Am, 2012.

Frequently Asked Questions About Hallux Valgus Treatment
RegenPAS is a patient service centre in Munich, not a clinic. We review your images and symptoms and send a request to several partner clinics at once. Clinics that can accept you send their own conditions and price; prices differ between clinics, and you choose the option that suits you. The coordinator replies within 24 hours, and a clinic physician’s preliminary opinion follows in 1–3 business days. We then arrange the appointment, visa invitation, interpreter, transfers and accommodation. Treatment decisions are made by the clinic physician. Contact a coordinator.
Your MRI (or CT, X-ray) report and the images if you have them, plus a short description of your symptoms and previous treatment. Send them via the form on the website — the assessment is free and without obligation: the coordinator replies within 24 hours, and the clinic physician’s preliminary opinion follows in 1–3 business days.
The cost depends on the method, the diagnostics needed and the clinic itself: prices differ between clinics. We request offers from several clinics and send you their conditions and quotes so you can compare. Price guidance is on the treatment cost page. For an outpatient procedure, 2–3 days in Munich are usually enough: examination, procedure and follow-up visit.
Clinic and method matching — free of charge
Describe your case and attach your MRI report. We will identify clinics that use the relevant methods and forward your request to them. No obligation; we reply within 24 hours.
