If you have neck or back pain after even a minor injury and your spine is fused, seek urgent imaging. A fused spine fractures like a long bone, and these fractures are easily missed and can injure the spinal cord. Also seek urgent care for new leg weakness or bladder disturbance.
An inflammatory condition of the spine and the joints where it meets the pelvis. Over years the inflamed vertebrae can fuse into a single rigid column, and the hips are frequently affected in the process.
This condition typically begins in young men in their twenties and is often misdiagnosed as ordinary back pain for years. Modern biologic medication has changed its outlook substantially — the fusion that once seemed inevitable is now frequently preventable.
Inflammation begins where ligaments attach to bone, particularly at the sacroiliac joints where the spine meets the pelvis. Over time the body responds by forming new bone at these sites, and the vertebrae gradually bridge together until the spine fuses into a rigid column, often in a stooped posture.
The pattern of pain is what distinguishes it from ordinary back pain and is the most useful diagnostic clue. Inflammatory back pain begins gradually before the age of forty-five, is worse in the morning with stiffness lasting more than half an hour, wakes the patient in the second half of the night, and — crucially — improves with exercise and worsens with rest. Mechanical back pain does the opposite.
Beyond the spine, the hips and shoulders may be involved, and inflammation can affect the eyes causing a painful red eye that needs urgent ophthalmology, the bowel, and occasionally the heart valves and the aorta.
The most consequential development has been biologic medication. Drugs targeting specific inflammatory pathways control the disease effectively in a large proportion of patients, and starting them early can prevent the structural fusion that used to define the condition. They are available in India at a fraction of Western prices.
A spine fused by ankylosing spondylitis behaves mechanically like a long bone — it is rigid and brittle, and it can fracture with an injury that would not harm a normal spine. These fractures are unstable, easily overlooked on plain X-rays, and can injure the spinal cord. If you have a fused spine and sustain any injury with new neck or back pain, insist on CT imaging rather than plain X-rays alone. This is also why your anaesthetist must know about your diagnosis before any operation.
Diagnosis rests on the pattern of symptoms supported by imaging and blood tests.
This single question separates inflammatory back pain from mechanical back pain more reliably than any scan. Inflammatory pain is worse with rest and better with movement; mechanical pain is the reverse. If your back pain began in your twenties, wakes you at night and eases when you get up and move, that pattern deserves proper assessment even if previous X-rays were reported as normal.
Medication is the treatment. Surgery addresses damage that has already occurred.
Daily exercise is genuinely part of the treatment rather than an adjunct, and it is one of the few conditions where this is unambiguously true. Regular stretching and postural work maintain mobility and slow the development of deformity. Swimming is particularly valuable. Stopping smoking matters, since smoking accelerates progression.
Regular non-steroidal anti-inflammatory drugs are the first-line treatment and are effective for symptoms in many patients. There is some evidence that continuous use may slow new bone formation, though this remains debated. Kidney function and stomach protection need monitoring.
Drugs blocking TNF or interleukin-17 are highly effective where anti-inflammatories are insufficient, controlling symptoms and inflammation and potentially preventing progression to fusion. Screening for tuberculosis and hepatitis is required first. These are available in India, including biosimilars, at substantially lower cost than in Europe or North America.
Hip replacement in ankylosing spondylitis is frequently transformative, restoring mobility in a young patient whose hips have fused. Corrective spinal osteotomy for severe fixed deformity, where a patient cannot look ahead, is a major and specialised operation performed at a small number of centres.
Active inflammation calls for medication. Established fusion without inflammation calls for surgery where function is limited. Both can coexist.
Hip involvement is frequently the greatest source of disability and the most rewarding to treat, and it is often overlooked while attention focuses on the spine.
A fused, rigid neck makes intubation difficult and dangerous if unanticipated. The anaesthetist must know beforehand, and this influences where surgery should be performed.
If you have active disease and have never been offered biologic medication, that conversation should happen before any surgical one. It is the treatment that changes your long-term future.
An acute painful red eye needs ophthalmology the same day, and any spinal injury in a fused spine needs CT imaging urgently. Both are local emergencies rather than reasons to travel.
Photographs taken on your phone are fine. Reports in Arabic, Russian or Bengali are fine — we translate them ourselves.
Not cured, but it can be controlled very effectively. Biologic medication suppresses the inflammation in a large proportion of patients, relieving symptoms and potentially preventing the fusion that used to be considered inevitable. Started early, modern treatment changes the trajectory of the disease substantially.
For a young patient with hips destroyed or fused by ankylosing spondylitis, hip replacement is frequently one of the most transformative operations in orthopaedics — restoring the ability to sit, walk and function. You should expect revision surgery at some point over a lifetime, but that is not a reason to spend decades unable to walk.
Because a fused, rigid neck makes it difficult or impossible to position the head for standard intubation, and forcing it risks spinal injury. An anaesthetist who knows in advance can plan an alternative technique. Never assume this has been communicated — say it yourself before any operation.
Yes. TNF inhibitors and IL-17 inhibitors, including biosimilar versions, are available at substantially lower cost than in Europe or North America. For some patients this alone justifies a consultation here — establishing the diagnosis, completing the required screening, and setting up treatment that then continues at home.
Generally not routinely. HLA-B27 is common in healthy people and having it does not mean the condition will develop. What matters more is being alert to the symptom pattern — back pain starting in the twenties, morning stiffness, night waking, improving with exercise — and seeking assessment promptly if it appears.
No, the opposite. This is one of the few conditions where regular exercise is genuinely part of the treatment rather than merely helpful. Daily stretching, postural work and swimming maintain mobility and slow deformity. Rest makes inflammatory pain worse, which is itself a diagnostic clue.
