Q1. Is ageing spine the same as degeneration due to wear and tear? Does it only affect the elderly?

Many people confuse "spinal ageing" with "wear and tear." While they are related, they are not identical. We are all living organisms, with metabolisms and the ability to repair ourselves. When we are young, our ability to repair and metabolism are faster than strain and degeneration, so our body functions are not significantly affected, and we can cope with the demands of daily life. However, as we age, our metabolism and repair abilities slow down compared to wear and tear, and spinal ageing begins. Ageing is inevitable and everyone experiences it, but the rate of progression varies from person to person. If the spine is overused, wear and tear may outpace self-repair, leading to premature degeneration. This can occur at any age.

Many factors influence the speed of ageing. For example, genetics can affect some people, leading to a later onset of ageing. Lifestyle and work habits are also important. Long-term poor posture and a lack of exercise can accelerate spinal ageing. Finally, smoking can increase the risk of spinal degeneration, so quitting is recommended.

Q2. What happens when the spine ages?

First, we must understand that the spine has three primary functions: supporting the body, controlling movement, and protecting the spinal cord and nerves within it. In terms of support, ageing can cause intervertebral discs to lose elasticity and spinal joint strain. Insufficient bone strength can lead to compression fractures. In severe cases, spinal deformities such as scoliosis and kyphosis can develop. With ageing, muscles lose strength and flexibility, and motor control declines. Spinal degeneration can also lead to stenosis of the spinal canal or intervertebral foramen, resulting in compression of the spinal cord or spinal nerves. Patients may experience neurological symptoms such as numbness or muscle atrophy, loss of coordination, and a tendency to fall. These are all potential symptoms of spinal ageing.

Q3. How is ageing spine diagnosed?

Everyone experiences spinal ageing. If it is simply ageing with no symptoms or only mild symptoms, I do not consider it a disease. Therefore, if a patient has no symptoms, no specific diagnosis is necessary. However, a small number of people experience symptoms, such as pain and spinal stiffness. If the spinal canal and the intervertebral foramen become narrow, the spinal cord or nerves may be compressed, leading to neurological symptoms. Furthermore, degeneration can lead to spinal instability, which can lead to deformities such as spondylolisthesis, scoliosis, or kyphosis. Doctors need to identify the root cause of the symptoms; this is the key to diagnosis.

Q4. How is ageing spine managed? What are the treatment outcomes?

When the spine ages, the management of spinal degeneration depends on whether the patient is symptomatic. If there are no symptoms, treatment is not necessary. To preserve spinal function for daily needs, one just needs to have a healthy lifestyle, do moderate exercise and avoid smoking. However, if symptoms are present, treatment is delivered based on specific symptoms observed. For instance, symptoms such as back pain or reduced mobility can often be managed through exercise, physiotherapy, and appropriate medications. 

For most patients without neurological symptoms, doctors generally do not recommend surgery, typically starting with non-surgical treatment. If the treatment is effective, rehabilitation can continue. If the patient does have neurological symptoms, the doctor will assess their severity and the degree to which they affect neurological function. Surgery may be necessary in severe cases, but this is not common. As for effectiveness, most patients can control their symptoms, and surgical results are also satisfactory, especially for symptoms due to nerve compression. However, accurate diagnosis and treatment sequencing are crucial.

Q5. When should surgical treatment be considered?

Only a small number of patients require surgery. This is mainly because the patient's symptoms are severe, have not responded well to non-surgical treatment, and have persisted for a reasonable period. In this case, surgery should be considered. However, if the patient's neurological function has been affected, especially in severe cases, surgery should be performed as soon as possible.

There are different types of surgery, and the choice depends on the patient's symptoms. If the pain is caused by spinal instability, internal fixation and fusion may be necessary. If nerve compression is present, decompression may be necessary. If the spine is deformed, correction and fixation with fusion may be necessary. No single surgery is suitable for all patients; the procedure depends on the patient's symptoms.

Q6. Can nutritional supplements delay spinal ageing?

There are many health supplements on the market, but their effectiveness may not be scientifically proven or thoroughly researched. Personally, I believe a balanced diet with adequate nutrition is sufficient. Additionally, strengthening and stretching exercises can strengthen the spine and muscles, improve back mobility, and maintain spinal health.

Q7. Can I exercise if I have an ageing spine?

For most patients, I think swimming is a good option, and the results are generally positive. Swimming is very beneficial for spinal health. If you are looking for targeted results, consult a rehabilitation doctor or physical therapist. However, if you have severe medical conditions, such as a serious heart disease, you should consult your family doctor first.
