Kyphosis Surgery

A rounded back has more than one cause. The right operation depends on which one you have.

A meta-analysis of 1,147 patients with Scheuermann kyphosis found that surgery from the back alone, with posterior osteotomies, corrects the curve as well as the older two-stage operation through the chest and the back.

What kyphosis is

Every spine curves forward in the chest, and a curve of roughly 20 to 45 degrees on a standing X-ray counts as normal. Kyphosis means more than that. A rounded back from slouching and a sharp hump from a collapsed vertebra are different problems with different treatments.

The cause of a kyphosis matters far more than its angle.

When surgery makes sense

Most kyphosis never needs an operation.

Hospitals in Istanbul publish a threshold of around 60 degrees for considering surgery, and surgeons in the spine literature quote 70 to 75 degrees for Scheuermann kyphosis in particular. The number starts the conversation. Pain, progression and balance finish it.

Scheuermann kyphosis in teenagers and young adults

Surgery for Scheuermann kyphosis used to mean two operations, one through the chest to loosen the front of the spine and one through the back to fix it. Posterior-only surgery has largely replaced that. A 2021 meta-analysis in the Journal of Neurosurgery Spine pooled 13 studies and 1,147 patients with an average age of 18 and found the same correction from the back alone as from the combined approach, as long as the surgeon added posterior shortening osteotomies, and an earlier meta-analysis in the European Spine Journal found less blood loss, shorter operations and fewer junctional problems above and below the fusion with the posterior-only operation. The fusion commonly runs from the upper chest to the junction with the lower back, often ten levels or more, and teenagers usually stand and walk the day after surgery and return to school within four to six weeks, with sports that involve contact or heavy lifting waiting for a solid fusion at around a year.

Kyphosis in adults

In adults the question shifts from the angle of one curve to the balance of the whole body. A spine that tips the head forward of the pelvis makes the back muscles work all day to hold you upright, and the result is fatigue, pain and a stooped walk. Correction may need larger osteotomies, including a pedicle subtraction osteotomy that removes a wedge through a whole vertebra, and fusions that run from the chest to the pelvis. Adults who do well after correction share three things, namely pain and stooping that come from the imbalance itself, bone strong enough to hold screws, and readiness for a recovery measured in months rather than weeks, and the first consultation tests exactly those three points with standing X-rays of the whole body, a bone density scan and a frank conversation about daily life. Ankylosing spondylitis forms a special group, because the spine is already fused and brittle, and a single wedge osteotomy in the lower back can lift the gaze back to the horizon.

Those figures explain why adult deformity surgery is planned slowly, with bone density tests, nutrition and weight addressed before the operation.

Kyphosis from a vertebral fracture

A vertebra that collapses from osteoporosis wedges the spine forward. Two procedures inject cement into the broken bone through a needle. Vertebroplasty injects it directly. Kyphoplasty first inflates a small balloon to restore some height, then fills the cavity.

The evidence is mixed. An Australian trial in the New England Journal of Medicine in 2009 compared vertebroplasty with a sham procedure in 78 patients and found no difference in pain at any point up to six months. The FREE trial in the Lancet the same year compared kyphoplasty with non-surgical care in 300 patients and found better physical function at one month, 7.2 points against 2.0 on a quality-of-life scale. Neither trial compared kyphoplasty with a sham. Many surgeons now reserve cement for fractures that stay painful after several weeks of good pain control, and treat the osteoporosis in every case.

Treating the osteoporosis prevents the next fracture. Cement only treats this one.

The operation, step by step

Risks, with what is done about each

In the adult deformity study, five factors raised the complication rate.

This table scrolls sideways on a narrow screen. Swipe or drag to see every column.

• Spinal cord injury. Rare, and the reason for continuous monitoring. A change in the signals during correction prompts the team to reduce the correction at once.
• Junctional kyphosis. The segment just above the fusion can bend forward over the first two years, especially in adults. Avoiding overcorrection, careful choice of the top vertebra and, in weak bone, cement or bone-building medicine reduce it.
• Blood loss. Osteotomies bleed. Medicines that reduce bleeding, blood salvage and a transfusion when needed manage it.
• Infection. Antibiotics treat wound infection, and a deep infection needs a washout with the implants usually kept.
• Screw loosening and nonunion. More likely in weak bone and in smokers. A second operation fixes a rod or a fusion that fails to heal.

Recovery, month by month

Fused segments of the spine will not bend again. Most people notice little, because the movement comes from the segments above and below.

How long to stay in Istanbul

Two to three weeks for a fusion. A published Istanbul hospital page gives five to seven days in hospital, and the rest of the stay covers walking practice, a wound check, the removal of stitches and a standing X-ray before the flight. Cement procedures are shorter. A kyphoplasty package from another Istanbul hospital lists five hospital days and ten to fifteen days in the country, though many patients walk comfortably the next day.

Flying waits for a healed wound, safe walking and the surgeon's letter, and on the plane an aisle seat, a walk every hour and a lumbar cushion make a long flight easier.

What decides the cost

Levels fused, the type of osteotomy, the screws and rods, spinal cord monitoring, the nights in intensive care and on the ward, blood products, and rehabilitation in Istanbul set most of the figure, and a revision of earlier surgery costs more than a first operation. For a cement procedure, the number of fractured levels decides it. Your health moves the figure too, in ways a published package cannot know. Osteoporosis that needs bone-building injections for some months before surgery, a smoker who must stop for several weeks so the fusion can heal, diabetes that needs tighter control, heart or lung disease that calls for extra tests, a high body weight that lengthens the operation, and earlier spine surgery with old screws to remove each add tests, sometimes a longer stay and occasionally a different plan, which is why the figure you receive should follow a review of your own X-rays rather than precede it.

Published Istanbul packages list the consultation, diagnostic tests, the operation, the hospital days, the first follow-up visit and airport transfers, and some include complication insurance. Flights and hotel nights sit outside many of them. A quote you can compare names the levels and the implants, counts intensive care and ward nights, and says whether monitoring and imaging are included. That figure comes only from a spine surgeon reading your standing X-rays and MRI. The review costs nothing.

Arranging the trip

A coordinator answers the first WhatsApp message and stays with you to discharge, and the number keeps working after you fly home. English, Arabic, French, Russian, Serbian, Romanian and Spanish are spoken by the team, with an interpreter for other languages. A companion bed lets one person stay in the room every night of the admission, and the international patients office books the hotel for the nights before and after and sends the invitation letter for a medical visa about ten days before travel. Transfers are arranged. Halal, vegetarian and diabetic meals come from the hospital kitchen, a prayer room sits on site, and a request for a female physician goes to the department with your first message.

Bring every earlier spine X-ray you have.

Once you are back home

Standing X-rays at three months, six months, one year and two years show whether the fusion has become solid and whether the segments above and below are holding, and your local surgeon can take them while the coordinator passes them to the surgeon in Istanbul. Adults with weak bone continue osteoporosis treatment for years, because a new fracture next to the fusion is a real risk.

New leg weakness or numbness, loss of bladder or bowel control, a fever with a red or leaking wound, or a sudden new pain at the top of the fusion. Each needs a doctor the same day.
