Bunion surgery in Barcelona
A bunion is the most common forefoot deformity, and one of the most poorly explained. It is not a callus, it is not caused by your shoes, and it will not go away with insoles. It is a progressive displacement of bone — and when it becomes painful and limiting, it has a surgical solution that looks very little like the operation many patients remember their parents having.
This page explains what hallux valgus actually is, how its severity is measured, what conservative treatment can and cannot achieve, when surgery is indicated, which techniques exist and what recovery looks like week by week. It is written by the practice of Dr. Fabio D'Angelo, orthopaedic foot and ankle surgeon in Barcelona.
What a bunion (hallux valgus) is
A bunion is a progressive deformity of the first metatarsophalangeal joint, where the big toe meets the foot. Two things happen at once: the big toe drifts towards the smaller toes, while the first metatarsal moves away in the opposite direction. The bump you see on the inner border of the foot is not new bone growth — it is the head of the metatarsal, now left exposed.
That distinction matters, because it explains why no external measure corrects it. No cream, insole, spacer or exercise can return displaced bone to its position. What those measures can do is relieve symptoms and, in some cases, slow progression.
Hallux valgus is also an evolving deformity: it tends to increase over the years. The rate varies considerably between individuals and cannot be predicted precisely at a first consultation.
When it stops being a cosmetic matter
Many people live for years with a visible bunion and barely any discomfort. Patients usually seek advice when several of these appear together:
- Pain over the prominence when walking or where the shoe rubs, sometimes with redness or bursitis.
- Pain under the forefoot (metatarsalgia): when the big toe stops carrying its share of load, the central metatarsals take it on.
- Increasing difficulty finding footwear, with a gradual surrender of styles that used to be tolerable.
- Associated deformities: hammer toes, claw toes, or displacement of the second toe.
- Stiffness of the joint, or loss of big-toe push-off when walking.
- Altered gait, overloading the knee, hip or lower back in advanced cases.
The decision to operate rests on symptoms and functional limitation, not on how the foot looks. A striking bunion that neither hurts nor limits can be monitored; a moderate one that prevents normal walking justifies assessment.
Causes and risk factors
The primary cause is structural and inherited. What is passed on is not the bunion itself but the type of foot that favours it: a rounded first joint surface, hypermobility of the first ray, a flat or pronated foot, or a relative metatarsal length that alters how load is shared.
Other factors act on that foundation:
- Sex and age. Clearly more frequent in women, and prevalence rises with age.
- Ligamentous laxity and connective tissue disorders.
- Inflammatory arthritis, particularly rheumatoid arthritis.
- Neuromuscular conditions that alter the balance of forces on the toe.
- Footwear, as an aggravating factor. Narrow, high-heeled shoes accelerate a bunion and make it symptomatic in a predisposed foot, but do not create the deformity in a foot that was not.
This explains a common consultation: people who have never worn heels and have pronounced bunions, and people who have worn them all their lives without developing any.
How severity is graded
Assessment is not done by eye. It is measured on a weight-bearing radiograph — standing, under body weight — because the deformity changes magnitude when the foot loads. Two angles define the picture:
- Hallux valgus angle (HVA): the deviation of the big toe relative to the first metatarsal.
- Intermetatarsal angle (IMA): the separation between the first and second metatarsals.
From these, the deformity is broadly classified as mild, moderate or severe. That grading, together with joint congruence, cartilage condition and first-ray mobility, determines which techniques are viable. The same radiological grade may be treated differently in two patients of different age, activity level and expectations.
Clinical examination completes the picture: joint mobility, first-ray hypermobility, the state of the lesser toes, any associated metatarsalgia, and gait analysis.
Conservative treatment: what helps and what does not
It is worth stating plainly: no conservative treatment corrects hallux valgus. The deformity is bony. What conservative treatment does achieve — and this is not nothing — is reduced pain, better footwear tolerance and, in some cases, slower progression.
Measures with genuine value:
- Appropriate footwear: a wide toe box, moderate heel height, soft material over the prominence. The most effective measure, and the most ignored.
- Custom foot orthoses, particularly where there is pronation or associated metatarsalgia.
- Physiotherapy and intrinsic foot muscle work.
- Silicone shields and spacers for friction, with symptomatic effect.
- Occasional anti-inflammatories during bursitis flare-ups.
What does not work: night splints do not correct the deformity in adults, and no over-the-counter product "dissolves" a bunion. Worth knowing before investing time and money.
The practice also offers podiatric physiotherapy and supportive treatments for symptom management while the timing of surgery is decided.
When surgery is indicated
Surgery is considered when several of these apply:
- Persistent pain limiting daily, working or sporting activity.
- Failure of properly conducted conservative treatment.
- Documented progression of the deformity.
- Secondary problems appearing: transfer metatarsalgia, hammer toes, dislocation of the second toe, pressure ulcers.
- Loss of joint mobility that alters gait.
A purely cosmetic motive is not sufficient indication. This is surgery with a real recovery period, and that conversation is part of the consultation.
Which techniques exist
There is no single bunion operation. There is a family of procedures, and the choice depends on the angles, first-ray mobility, cartilage condition and the patient.
Open surgery with osteotomy
The classical approach. A controlled cut of the bone is made — chevron, scarf or other variants depending on location — and stabilised with screws or staples. It is a widely validated technique and remains the right answer in many cases, particularly for larger deformities. It requires a longer incision and, with it, more disturbance of the soft tissues.
Percutaneous or minimally invasive surgery (MIS)
The same bony corrections are performed through millimetric incisions, under fluoroscopic control with dedicated burrs. It reduces soft-tissue trauma and postoperative inflammation. It demands specific instrumentation and a long learning curve.
Correction with the TightRope® system
Rather than cutting bone to close the intermetatarsal angle, a high-strength suture with buttons draws the first metatarsal towards the second and holds the correction. The Mini TightRope® system is developed by Arthrex. Because it does not rely on an osteotomy, it avoids bone healing as the limiting step in selected cases. It is not applicable to every bunion and requires careful indication.
Dr. D'Angelo's endoscopic approach
Dr. D'Angelo performs the TightRope® correction through an endoscopic approach, working under direct vision through minimal portals. It is the core of what the practice calls the SPARE™ Method — Surgery Preserving Anatomy, Restoring, Endoscopically — preserving healthy anatomy and avoiding unnecessary bone cuts whenever clinically appropriate. The endoscopic TightRope® technique is explained in detail on its own page.
Arthrodesis and first cuneiform procedures
Where there is marked first-ray hypermobility, advanced joint arthritis or recurrence after previous surgery, correction may require working at the base of the metatarsal or fusing the joint. It is the least frequent option, but the most stable in that particular scenario.

What recovery actually looks like
The timelines below are indicative. They vary with the technique used, the severity of the deformity, whether one or both feet were operated on, and individual factors. The specific plan is provided in writing before surgery.
First few days
Functional dressing and a postoperative shoe. Rest with the foot elevated above heart level for most of the day: this is the single measure with the greatest effect on swelling. Local ice and prescribed analgesia. Discomfort is usually greatest in the first 48 to 72 hours.
First weeks
Sutures are removed at the stated interval, and dressing changes plus guided toe mobilisation begin — key to avoiding stiffness. Weight-bearing follows the prescribed protocol in the postoperative shoe. Driving depends on which foot was operated on, the type of anaesthesia and your ability to control the vehicle safely; the right foot generally takes longer.
Between the first and third month
Gradual transition to wide, flexible athletic footwear. Longer walking and low-impact exercise resume. Swelling towards the end of the day is normal and expected for considerably longer than most patients anticipate.
From the third month
Progressive return to higher-impact sport according to progress. Conventional footwear becomes increasingly tolerable. Residual swelling and scar maturation can continue for up to a year.
Return to work depends on the role: a desk-based job allows an earlier return than one requiring prolonged standing, walking or physical effort.
Risks, complications and recurrence
All surgery carries risk, and honest information is part of consent. In hallux valgus surgery the most relevant are:
- Recurrence: the deformity returning over time.
- Overcorrection (hallux varus), with the toe deviating the other way.
- Stiffness of the joint and loss of flexion.
- Transfer metatarsalgia: pain under the central metatarsals from a changed load distribution.
- Delayed union or non-union in osteotomy techniques.
- Hardware irritation, occasionally requiring removal.
- Altered sensation from irritation of cutaneous nerve branches.
- Infection, venous thrombosis and general complications — uncommon but possible.
On recurrence it is worth being precise: no technique guarantees a bunion will never return. Published figures vary widely with initial severity, technique, patient selection and length of follow-up, so quoting a single percentage would be misleading. What does consistently reduce the risk is correct indication, a correction matched to the grade of deformity, and adherence to postoperative instructions.
Revision surgery
Previous surgery does not rule out further treatment. Dr. D'Angelo sees patients with recurrent deformity, persistent pain, stiffness, overcorrection, hardware problems or unsatisfactory results from earlier operations.
Revision surgery is technically more demanding than primary surgery: there is scar tissue, the anatomy is altered, and there may be loss of length or bone stock. It requires detailed assessment with fresh imaging before any option is proposed.
Common questions about bunion surgery
Does bunion surgery hurt?
No, you will not feel pain during the procedure, as appropriate anesthesia is used. After surgery, it is normal to experience some discomfort and swelling, particularly during the first few days. Most patients find that their pain is well managed with prescribed medication, rest, elevation, and ice.
When will I be able to walk after surgery?
Walking is encouraged according to your personalized recovery plan. Many patients are able to bear weight in a protective postoperative shoe shortly after surgery, but the timeline varies depending on the severity of the bunion and the procedure performed.
Can both feet be operated on at the same time?
In selected cases, yes. Whether simultaneous surgery is appropriate depends on your general health, the severity of the deformities, the support you have at home and your recovery goals. This will be assessed during your consultation.
Can the bunion come back after surgery?
No surgical procedure can guarantee that a bunion will never recur. However, careful surgical planning, precise correction, and following your postoperative instructions significantly reduce the risk. Dr. D'Angelo's goal is to achieve a stable, long-lasting correction while preserving the natural function of your foot.
Will I be able to wear heels again?
Many patients are able to wear them again for special occasions once healing is complete, though comfort depends on the height and style of the shoe as well as your own anatomy. The goal is to give you back a healthy, pain-free foot, so that you have more options — not fewer — when choosing footwear.
Am I a candidate for the endoscopic TightRope® technique?
It depends on the severity of the bunion, joint mobility and flexibility, bone alignment and quality, your age and activity level, your occupation and lifestyle, previous foot surgery if applicable, and your expectations. During your consultation Dr. D'Angelo will assess this and explain which options are viable in your case.
