Medication and exercises are the first line of management.
Cervical spondylosis is a very common condition where there is chronic degeneration of the bones of the neck (cervical spine) and the cushions between the vertebrae (intervertebral disc). This is managed by cervical spine surgery where the worn-out discs or bone spurs are removed—depending on the underlying problem. Sometimes the gap would be filled by a graft of bone or other implants made of metal combined with bone.
Symptoms of spondylosis may be as mild as occasional backaches or could be chronic low back pain that is severe enough to limit daily activities. The mechanical type of pain increases as more stress or load is placed on the lower back. Bending, lifting, and twisting are the types of movement that may exacerbate it.
Degenerative Disc Disease requires surgery only rarely. The commonly used non-surgical treatments include anti-inflammatory drugs, physiotherapy, and exercise programs. Surgery is required when the patient has very severe debilitating symptoms, pain interferes with activities of daily living, and non-surgical treatment has failed after a reasonable period of time, usually at least six months.
Fusion surgery is usually done, and this permanently stops the motion of the spine at the level of the degenerated disc. This helps to relieve pain. Fusion surgery works best when limited to one or two discs. As we have five discs in the lumbar spine, the un-fused discs take over to provide adequate function of the lower back.
Sometimes an artificial disc can also be inserted into the disc space after removing the entire degenerated disc. This helps to restore disc height, improve spine function, and ease the debilitating pain.
Surgery is considered for disc prolapse if the symptoms of the bulging disc have not settled after about six weeks or so. One may opt for:
Keyhole surgery or microdiscectomy spine surgery, which is typically performed when there is a prolapsed disc in the lumbar (lower back) region pressing against a nerve.
Sometimes an artificial disc can also be inserted into the disc space after removing the entire degenerated disc. This helps to restore disc height, improve spine function, and ease the debilitating pain.
Disc replacement – Here, an artificial disc is implanted into the spine to imitate the functions of a normal disc (carry load and allow motion). Artificial discs are usually made of metal or plastic-like (biopolymer) materials, or a combination of the two. The treatment for bulging disc and prolapsed disc is disc replacement done in the cervical (neck) spine.
For all the above conditions, surgery is indicated if the slippage progressively worsens or if back pain does not respond to non-surgical treatment and begins to interfere with daily life. In the congenital and high dysplastic group, spondylolisthesis surgery is done at early stages to prevent neurological complications.
Abnormal curvatures of the spine are referred to as scoliosis and kyphosis. In the normal spine, there are normal curves if seen from the side, but the spine is seen as a straight column from the front. In scoliosis, the spine shows curvatures from the front. In kyphosis, there is abnormal forward bending of the spine.
Scoliosis is a Greek word meaning curvature. Ancient physicians thought poor posture was the primary cause of scoliosis. Today it is clear that scoliosis is either congenital (present at birth) or developmental and may be hereditary. The spine curves to the side in the shape of an “S” or “C”. The curvature is measured in degrees.
Types Of Scoliosis:- Scoliosis is classified according to the affected age groups:
Dextroscoliosis (curve to the right – common in thoracic spine)
Levoscoliosis (curve to the left – common in lumbar spine; rare in thoracic spine)
Thoracic scoliosis: middle spine (most common)
Lumbar scoliosis: lower spine
Thoracolumbar scoliosis: affects both lower thoracic and upper lumbar spine
Medication, physiotherapy, exercise to stabilize the spine and relieve pain.
For severe curvature, spinal fusion and instrumentation are done to center the head and trunk over the pelvis.
Staples on the convex side for differential growth.
Shape Memory Alloy (SMA) staples made of Nitinol used for fixation without fusion, allowing growth and deformity correction.
Extradural: outside the dura mater (most common)
Intradural: part of dura mater
Intramedullary: inside spinal cord
Extramedullary: inside dura but outside cord
