Why the spine surgery market is so strong

The global spine market is large, active and growing rapidly in revenues. Several dynamic forces, in addition to the aging of the population, are expected to affect the market and treatments during the next several years. While spinal fusion will always have a place, its share of the treatment market is expected to decline. Newer treatments such as total disc replacement and nuclear arthroplasty will erode the spinal fusion market, as these and other treatments which preserve spinal motion gain favor over the invasive and traumatic fusion of two or more spine segments.

Fundamentally, demographics are a huge driver of spine surgery growth, but the number and variety of different spine disorders and diseases supports and ongoing need for treatments, technologies and products.

Below are select data in support of the huge and growing worldwide spine surgery market (drawn from report #M510).

Congenital Disorders of the Spine




Kyphosis (hyperkyphosis)

Exaggerated curvature. Excessive kyphosis results in “hunchback” appearance. Can result from segmentation or formation defects.


Exaggerated curvature. Excessive lordosis results in “swayback” appearance. Usually appears in lumbar spine.

Scheuermann’s Kyphosis

Hyperkyphotic deformity observed in from 1% to 8% of children over the age of 20 or 11. Typically appears in thoracic spine.


Lateral curvature of the spine exceeding 10°. Primary age of onset between 10 and 15 years. Scoliosis in females much more likely to require treatment as it progresses.

Inflammatory and Infectious Diseases of the Spine





An inflammation of the disk space often related to infection. Most commonly appears in lumbar region.


Also called Sacroiliac Joint Injury. Can result from inflammation, infection, trauma, or other causes.


Describes inflammation of the meninges and subarachnoid space. Can result from bacterial, fungal, viral or parasitic agents; can also result from surgery or the administration of intrathecal agents.

Degenerative Diseases of the Spine


Degenerative Disease


Degenerative Disc Disease (DDD)

Can encompass degradation of bony architecture, discs,
or supporting muscles and ligaments of the spine.
Frequency increases with age.

Spinal Stenosis

Narrowing of the spinal canal, neurorecesses, and
neuroforaminal canals at any part along the spinal axis.
Can result from disc protrusion or other degenerative


Systemic skeletal disorder characterized by low bone
mass and loss of bone tissue. Especially prevalent in
postmenopausal women

Rheumatoid Arthritis

An inflammatory disease of no known cause that
primarily affects the peripheral joints. The disease has a
significant genetic component.

Mechanical Disorders of the Spine


Mechanical Disorder


Herniated Disc

Refers to the bulging or protrusion of the interior disc nucleus against or through the wall of the intervertebral disc. Predominantly appears in the lumbar spine.

Spinal Stenosis

Narrowing of the spinal canal, neurorecesses, and neuroforaminal canals at any part along the spinal axis.
Often due to age-related degenerative changes.


Usually refers to symptomatic compression of the spinal cord itself, sometimes linked to spinal stenosis.


Describes symptoms associated with compression of the nerve roots of the spine, often due to disc herniations or other factors.


Describes bony overgrowths or spurs (osteophytes) on vertebra, often linked to aging.


Describes the (usually) forward slippage of a vertebra relative to the one below. Most frequently occurs in the lumbar spine.
