Nuss Bar Removal
when the bar is due out and there is no route back

A bar placed to correct a sunken chest is designed to come out again, usually around three years after the repair. Removal is a far smaller operation than the original correction, and the published complication rate is low. The difficulty for many people is not the operation but the route to it: the surgeon who placed the bar may be abroad, may have moved, or may no longer be operating, and a substantial share of UK pectus repairs are now done privately or overseas. You do not have to return to the original surgeon to have a bar removed. Dr Lawrence Okiror, Consultant Thoracic and Robotic Surgeon (GMC 6150382), removes pectus bars placed elsewhere and sees patients from the age of 16 upwards at London Bridge Hospital and The Lister Hospital Chelsea within 2–3 days. Self-referrals welcome.

Around Three Years

The standard interval from repair to removal. In one single-institution series the median was 1,139 days, with a median age at removal of 19.1 years.

No Route Back Is Not a Dead End

Surgery abroad, a surgeon who has moved or retired, or a service that no longer exists. The bar still comes out, and a thoracic surgeon can remove one placed by someone else.

A Much Smaller Operation

Complications were reported in 4.8% of 542 removals, with none graded severe. Reported rates across the wider literature range from 2% to 15%.

  1. The bar is meant to come out at around three years.Long enough for the chest wall to remodel in its corrected position, and not so long that the operation becomes harder than it needs to be. The bar is a temporary support, not an implant to be left indefinitely.
  2. Leaving it much longer makes the operation harder, not the result better.In 542 removals, bars in place six years or more took longer to remove, had more bone formed around them and bled more — without any improvement in the final shape of the chest [2].
  3. Return to your original surgeon if you can, and if you cannot, that is not the end of it.The implanting surgeon knows exactly what was put in, which is why they are the first choice. Where that route has closed, the operation note or a chest X-ray tells another surgeon what they need to know.
  4. A bar in place complicates any future operation through the breastbone.Uncommon, but it happens. If a heart or chest operation is being planned and a pectus bar is still in, that has to be dealt with as part of the plan rather than discovered late.
  5. An unsatisfactory correction is a different problem from a bar that needs removing.Where the chest has not been adequately corrected and a redo repair is in question, the right destination is a pectus centre. That is said here plainly rather than discovered after an operation.

When should the bar actually come out?

The bar is not an implant in the way a joint replacement is. It is a temporary strut that holds the sternum in a corrected position while the chest wall remodels around it, and it is designed to be taken out again. The convention is around three years, and the published experience matches it: in a single-institution series of elective removals the median interval from insertion to removal was 1,139 days — a little over three years — with a median age at removal of 19.1 years [1].

Three years is a compromise rather than a magic number. Too short and the correction has not had time to hold; too long and the operation becomes more difficult for no gain. Most people are told the date at the time of their repair, and for those who had the operation in a settled service with a follow-up clinic, removal is simply booked. The people who reach this page are usually those for whom that did not happen.

If you are past three years, you have not missed a deadline. Bars are removed successfully well beyond that point, and the section below sets out exactly what the delay costs and what it does not.

What a long-standing bar costs you

The most useful study here examined 542 patients having bars removed and compared those in place under six years with those in place six years or more [2]. It answers the question people actually ask, which is whether leaving it has done any harm.

85 vs 55 minutes of operating time for bars left six years or more, against those removed at around four years
68.8% had bone formed around the bar in the long-standing group, against 46.9% in the standard group
No difference in complication rate or in the radiological result between the two groups

Read together, those findings say something reassuring and something practical. The reassuring part is that a bar left far longer than intended does not ruin the result — the chest looked the same afterwards and the complication rate was not higher. Anyone who has spent years worrying that they have left it too late can put that down.

The practical part is that it is a bigger operation than it needed to be. Bone forms around a bar that has been in place for years, so it has to be freed before it can be withdrawn, which takes longer and bleeds more. Overall, complications after bar removal were reported in 4.8% of that series with none graded severe, and rates across the wider literature fall between 2% and 15% [2,3]. There is no advantage in waiting, and a modest cost to it.

When there is no route back to the surgeon who placed it

The standard advice, and the advice given here too, is to return to the surgeon who performed the repair. They know precisely what was put in, how many bars there are, how they were secured, and where the stabilisers sit. That is genuine knowledge and it makes the operation simpler. But it presupposes that the route is still open, and for a good number of people it is not.

The repair was done abroad

The commonest reason. Travelling back for a day-case-scale operation is expensive and impractical, and some people have since moved country entirely. The bar still has to come out, and it can come out here.

The surgeon has moved, retired, or no longer operates

Services move and people change jobs. A patient whose repair was done at a hospital that no longer offers the operation can find there is nobody at that address who does it.

Follow-up simply lapsed

People move away for university or work, appointments are missed, and years pass. This is common and it is nobody’s fault. It is also the group most likely to arrive well past three years.

What is needed to plan the operation safely is information about what is in there. The operation note is ideal — number of bars, stabilisers, wires, which side. Where none of that survives, a chest X-ray shows the number and position of the bars and is usually sufficient. Bring whatever you have, including photographs of discharge paperwork, and do not delay booking an assessment because the documentation is incomplete.

What removal involves and how long it takes

The bar is approached through the original incisions at the sides of the chest, so there is generally no new scar. Any stabilisers or fixation wires are released first, along with any bone that has formed around the bar. The bar is then straightened and withdrawn. It is done under general anaesthetic, and while some centres perform it as a day case, a short inpatient stay is common and is the safer default where the bar has been in a long time.

The comparison people want is with the original repair, and it is not close. The Nuss procedure moves the sternum into a new position against the resistance of the whole chest wall, and the first weeks afterwards are genuinely painful. Removal releases that structure rather than creating it. Operating times in the published series run from under an hour for a straightforward removal to something over an hour where bone has formed around a long-standing bar [2].

Recognised complications are uncommon but real, and they are the reason this is done in a proper theatre with proper anaesthetic cover rather than treated as a trivial procedure. They include pneumothorax, bleeding, wound problems and, very rarely, injury to structures behind the sternum. That last risk is the reason that documentation of what was implanted, and a recent X-ray, matter before the day.

Problems with a bar that is still in

Pain that is new, or on one side only. Some discomfort is expected for months after a repair and then settles. Pain that arrives later, or that is clearly worse at one end of the bar, is worth assessing rather than enduring until the removal date.

A bar that feels as though it has moved. Displacement is a recognised problem and is one of the reasons for earlier removal or revision. A chest X-ray answers it directly, which is why an examination and a film are the first steps rather than a scan.

A prominence or a point you can feel at the end of the bar. Commonly the stabiliser rather than the bar itself. Usually nothing, but it deserves a look, particularly if the skin over it is thinned or sore.

Overdue removal with no symptoms at all. The commonest reason people arrive here, and there is no need to develop a problem before being seen. If the bar is past its intended date, that alone is a reason to book an assessment.

A bar in place when you need another chest operation

Occasionally someone needs an operation through the breastbone — a cardiac procedure, a thymus gland operation, a mediastinal tumour — or a lung operation, and still has a pectus bar lying across the front of the chest. It is not a common scenario, but when it arises it is important, because the bar sits directly in the way of the approach and it changes the plan.

In most cases the bar is removed either in advance of the main operation or at the same sitting, and which of those is right depends on the urgency of the main procedure and on how long the bar has been in. What matters most is that the question is raised early. It is exactly the kind of detail that surfaces late, when the main operation is already being planned by a team focused on something else entirely.

If you have a bar in and any chest or heart operation is being discussed, say so at the first opportunity. It is also worth mentioning a bar to anyone arranging an MRI scan, because the implant needs to be identified and checked for compatibility beforehand.

When removal alone is not the answer

Some people arrive with a bar that is due out and a chest that has not been adequately corrected. Those are two different problems, and only one of them is solved by taking the bar out. Where the correction has not held, or where the original repair has left a result that needs revising, the operation required is a redo pectus repair — a technically demanding procedure that belongs in a pectus centre with a team that does it regularly.

That distinction is stated here rather than discovered afterwards. It is better to be told at the consultation that the right destination is somewhere else than to have a bar removed and then find the underlying problem is unchanged. Where that is the position, the referral is made and the reasoning explained.

The same applies to a first repair. This page is about removing a bar that is already in, not about correcting a sunken chest that has never been operated on. Anyone in that position needs a pectus service, and the section below explains where those currently sit in England.

Why so many UK patients were operated on privately or abroad

Pectus surgery has an unusual commissioning history in England. It was decommissioned as a routinely funded procedure, and although it has since been recommissioned in a restricted form, NHS England does not fund it routinely — the current policy admits only a small number of patients a year with severe physiological consequences. The predictable result is that a large share of repairs in this country have been carried out privately or overseas, which is precisely why so many people end up with a bar and no clear route to having it removed.

At the time of writing, pectus repair in England is concentrated at a small number of centres, with a national multidisciplinary team reviewing cases. A randomised trial, RESTORE, is running to establish whether surgery improves physical function compared with no surgery, and its result is expected to inform the next commissioning decision. Until then the position remains restrictive.

Removal sits outside all of that. It is not corrective surgery and no commissioning policy restricts it: a bar that has been placed needs to come out, wherever it was placed and however the original operation was funded. That is the single most useful thing to understand if you have been told that pectus surgery is not routinely available.

Booking an assessment and what to bring

Dr Okiror sees and treats patients from the age of 16 upwards, which covers most people reaching the point of bar removal. Younger or more complex patients are managed jointly with the paediatric team at Evelina London, and the arrangements are agreed individually. The relationship between age and this operation is set out further on the chest and lung surgery for teenagers and young adults page.

Bring the operation note from the original repair if you have it, or failing that the date, the hospital and the country. Any chest X-ray taken since the repair is useful. If you have none of this, come anyway — a film can be arranged and it answers most of the questions that matter for planning.

Private appointments at London Bridge Hospital and The Lister Hospital Chelsea are typically available within 2–3 working days, with outpatient consultations also available at the HCA clinics in Canary Wharf and the City of London. Self-referrals welcome. Bar removal is a coded, recognised procedure and is generally covered by insurance, though authorisation should be obtained in writing before booking, particularly where the original repair was self-funded or performed abroad. Second opinions are available for patients already under another team’s care.

How long can a Nuss bar stay in?
The usual point for removal is around three years after the repair. Published series bear that out: in one single-institution experience the median interval from insertion to removal was 1,139 days, a little over three years, with a median age at removal of 19.1 years. A bar left substantially longer is not a disaster, but it is a harder operation — a study of 542 removals found that bars in place six years or more took longer to remove, had more bone formed around them, and bled more, although the complication rate and the final result were no different. The practical message is that there is no benefit in leaving it, and there is a cost.
Does the surgeon who put the bar in have to take it out?
No. Where it is possible, returning to the surgeon who performed the repair is the sensible first choice, because they know exactly what was placed, how many bars there are, how they were fixed and which side the stabilisers sit on. But it is not a requirement, and for many people it is not possible. A thoracic surgeon can remove a bar placed by someone else, provided the operation note or at least a recent chest X-ray is available to establish what is in there.
I had my Nuss procedure abroad. Who removes the bar in the UK?
This is now a common situation, because a substantial share of UK pectus repairs are performed privately or overseas. The bar still has to come out, and it can be removed here. What helps most is documentation: the operation note if you have it, the number of bars, whether stabilisers or wires were used, and the date of the repair. Where none of that is available, a chest X-ray shows the number and position of the bars and is usually enough to plan the operation safely.
Is bar removal painful compared with the original operation?
It is a far smaller operation. The original Nuss repair involves forcing the sternum into a new position and is genuinely painful for some weeks. Removal releases that, works through the same lateral incisions, and does not disturb the chest wall in the same way. Most people describe the recovery as short. In published series the complication rate is low — 4.8% in one series of 542 removals, with no severe complications — and reported rates across the literature fall between 2% and 15%.
Is Nuss bar removal covered by insurance?
It is a recognised, coded procedure and is generally covered where the bar was placed for pectus excavatum, but cover depends on your policy and on how the original repair was funded. Policies differ particularly where the original operation was self-funded or performed abroad. The practical step is to obtain written authorisation from your insurer before booking, quoting the procedure code your insurer requires. Jo Mitchelson can provide a self-pay estimate if you would rather not involve an insurer.
Can the chest sink back in after the bar is removed?
Some loss of correction is recognised after bar removal, which is the reason the bar is left in for around three years rather than a few months — the chest wall needs time to remodel in its new position. Complete recurrence is uncommon after an adequate period of correction. The published work on delayed removal found no difference in the radiological result between bars removed at around four years and those left six years or more, which suggests that beyond the standard period, longer does not mean better.
My bar is causing pain or feels like it has moved. What should I do?
Have it assessed rather than wait for the scheduled removal date. Pain that is new, a bar that feels as though it has shifted, a prominence at one end, or discomfort on one side only are all reasons to be seen and to have a chest X-ray, which shows the position of the bar and any displacement. Displacement is one of the recognised reasons for earlier removal. It is not usually an emergency, but it is not something to monitor at home for months either.
I need heart or chest surgery and still have a bar in. What happens?
This is uncommon but it does happen — someone needs an operation through the breastbone, or a lung operation, and still has a pectus bar across the front of the chest. The bar has to be dealt with as part of planning that operation, and in most cases it is removed either beforehand or at the same sitting. It is worth raising early with whoever is arranging the main operation, because it changes the plan and it is the kind of thing that surfaces late if nobody asks.
Do you perform the Nuss repair itself?
This page is about removal, not primary correction. Pectus repair in England is currently concentrated at a small number of centres, with a national multidisciplinary team, and NHS England does not routinely commission it — a randomised trial, RESTORE, is running to inform that decision. Where someone needs a first repair, or a redo because the original correction has not held, the right route is a pectus centre rather than a removal service. That is said plainly here because an unsatisfactory result needs different expertise from a bar that simply needs taking out.
How old do I have to be?
Dr Okiror sees and treats patients from the age of 16 upwards, which covers most people reaching the point of bar removal — in one published series the median age at removal was 19.1 years. Younger or more complex patients are managed jointly with the paediatric team at Evelina London. The practical arrangements are agreed individually at the time of booking.
Do I need a GP referral?
Self-referrals welcome — no GP letter is needed before booking. Private appointments at London Bridge Hospital and The Lister Hospital Chelsea within 2–3 days. Bring the operation note from your original repair if you have it, along with the date, the hospital, and any chest X-ray taken since. New consultations from £250. Most major insurers accepted. Second opinions also available.
