Scoliosis is a medical condition in which a person's spine has a sideways curve. The curve is usually "S"- or "C"-shaped over three dimensions. In some, the degree of curve is stable, while in others, it increases over time. Mild scoliosis does not typically cause problems, but severe cases can interfere with breathing. Typically, no pain is present.
|Symptoms||Sideways curve in the back|
|Usual onset||10–20 years old|
|Risk factors||Family history, cerebral palsy, Marfan syndrome, tumors such as neurofibromatosis|
|Treatment||Watchful waiting, bracing, exercises, surgery|
The cause of most cases is unknown, but it is believed to involve a combination of genetic and environmental factors. Risk factors include other affected family members. It can also occur due to another condition such as muscles spasms, cerebral palsy, Marfan syndrome, and tumors such as neurofibromatosis. Diagnosis is confirmed with X-rays. Scoliosis is typically classified as either structural in which the curve is fixed, or functional in which the underlying spine is normal.
Treatment depends on the degree of curve, location, and cause. Minor curves may simply be watched periodically. Treatments may include bracing, specific exercises, and surgery. The brace must be fitted to the person and used daily until growing stops. Specific exercises may be used to try to decrease the risk of worsening. They may be done alone or along with other treatments such as bracing. Evidence that chiropractic manipulation, dietary supplements, or exercises can prevent the condition from worsening is weak. However, exercise is still recommended due to its other health benefits.
Scoliosis occurs in about 3% of people. It most commonly occurs between the ages of 10 and 20. Females typically are more severely affected than males. The term is from Ancient Greek: σκολίωσις, romanized: skoliosis which means "a bending".
Signs and symptoms
Symptoms associated with scoliosis can include:
- Pain in the back, shoulders, neck and buttock pain nearest the bottom of the back
- Respiratory or cardiac problems in severe cases
- Constipation due to curvature causing "tightening" of stomach, intestines, etc.
- Limited mobility secondary to pain or functional limitation in adults
- Painful menstruation
The signs of scoliosis can include:
- Uneven musculature on one side of the spine
- Rib prominence or a prominent shoulder blade, caused by rotation of the rib cage in thoracic scoliosis
- Uneven hips, arms, or leg lengths
- Slow nerve action
- Heart and lung problems in severe cases
- Calcium deposits in the cartilage endplate and sometimes in the disc itself
People who have reached skeletal maturity are less likely to have a worsening case. Some severe cases of scoliosis can lead to diminishing lung capacity, pressure exerted on the heart, and restricted physical activities.
Recent longitudinal studies reveal that the most common form of the condition, late-onset idiopathic scoliosis, causes little physical impairment other than back pain and cosmetic concerns, even when untreated, with mortality rates similar to the general population. Older beliefs that untreated idiopathic scoliosis necessarily progresses into severe (cardiopulmonary) disability by old age have been refuted by later studies.
The many causes of scoliosis include neuromuscular problems, and inherited diseases or conditions caused by the environment.
About 38% of variance in scoliosis risk is due to genetic factors, and 62% is due to the environment. The genetics are likely complex, however, given the inconsistent inheritance and discordance among monozygotic twins. The specific genes that contribute to development of scoliosis have not been conclusively identified. At least one gene, CHD7, has been associated with the idiopathic form of scoliosis. Several candidate gene studies have found associations between idiopathic scoliosis and genes mediating bone formation, bone metabolism, and connective tissue structure. Several genome-wide studies have identified a number of loci as significantly linked to idiopathic scoliosis. In 2006, idiopathic scoliosis was linked with three microsatellite polymorphisms in the MATN1 gene (encoding for matrilin 1, cartilage matrix protein). Fifty-three single nucleotide polymorphism markers in the DNA that are significantly associated with adolescent idiopathic scoliosis were identified through a genome-wide association study.
Adolescent idiopathic scoliosis has no clear causal agent, and is generally believed to be multifactorial. The prevalence of scoliosis is 1% to 2% among adolescents, but the likelihood of progression among adolescents with a Cobb angle less than 20° is about 10% to 20%.
Congenital scoliosis can be attributed to a malformation of the spine during weeks three to six in utero due to a failure of formation, a failure of segmentation, or a combination of stimuli. Incomplete and abnormal segmentation results in an abnormally shaped vertebra, at times fused to a normal vertebra or unilaterally fused vertebrae, leading to the abnormal lateral curvature of the spine.
Resulting from other conditions
Secondary scoliosis due to neuropathic and myopathic conditions can lead to a loss of muscular support for the spinal column so that the spinal column is pulled in abnormal directions. Some conditions which may cause secondary scoliosis include muscular dystrophy, spinal muscular atrophy, poliomyelitis, cerebral palsy, spinal cord trauma, and myotonia. Scoliosis often presents itself, or worsens, during an adolescent's growth spurt and is more often diagnosed in females than males.
Scoliosis associated with known syndromes is often subclassified as "syndromic scoliosis". Scoliosis can be associated with amniotic band syndrome, Arnold–Chiari malformation, Charcot–Marie–Tooth disease, cerebral palsy, congenital diaphragmatic hernia, connective tissue disorders, muscular dystrophy, familial dysautonomia, CHARGE syndrome, Ehlers–Danlos syndrome (hyperflexibility, "floppy baby" syndrome, and other variants of the condition), fragile X syndrome, Friedreich's ataxia, hemihypertrophy, Loeys-Dietz syndrome, Marfan's syndrome, nail–patella syndrome, neurofibromatosis, osteogenesis imperfecta, Prader–Willi syndrome, proteus syndrome, spina bifida, spinal muscular atrophy, syringomyelia, and pectus carinatum.
Another form of secondary scoliosis is degenerative scoliosis, also known as de novo scoliosis, which develops later in life secondary to degenerative (may or may not be associated with ageing) changes. This is a type of deformity that starts and progresses because of the collapse of the vertebral column in an asymmetrical manner. As bones start to become weaker and the ligaments and discs located in the spine become worn as a result of age-related changes, the spine begins to curve. The word 'de novo' is associated with this form of scoliosis as it means 'new', referring to the occurrence of the condition during later life.
People who initially present with scoliosis undergo physical examination to determine whether the deformity has an underlying cause and to exclude the possibility of underlying condition more serious than simple scoliosis.
The person's gait is assessed, with an exam for signs of other abnormalities (e.g., spina bifida as evidenced by a dimple, hairy patch, lipoma, or hemangioma). A thorough neurological examination is also performed, the skin for café au lait spots, indicative of neurofibromatosis, the feet for cavovarus deformity, abdominal reflexes and muscle tone for spasticity.
When a person can cooperate, he or she is asked to bend forward as far as possible. This is known as the Adams forward bend test and is often performed on school students. If a prominence is noted, then scoliosis is a possibility and an X-ray may be done to confirm the diagnosis.
As an alternative, a scoliometer may be used to diagnose the condition.
When scoliosis is suspected, weight-bearing, full-spine AP/coronal (front-back view) and lateral/sagittal (side view) X-rays are usually taken to assess the scoliosis curves and the kyphosis and lordosis, as these can also be affected in individuals with scoliosis. Full-length standing spine X-rays are the standard method for evaluating the severity and progression of the scoliosis, and whether it is congenital or idiopathic in nature. In growing individuals, serial radiographs are obtained at 3- to 12-month intervals to follow curve progression, and, in some instances, MRI investigation is warranted to look at the spinal cord.
The standard method for assessing the curvature quantitatively is measuring the Cobb angle, which is the angle between two lines, drawn perpendicular to the upper endplate of the uppermost vertebra involved and the lower endplate of the lowest vertebra involved. For people with two curves, Cobb angles are followed for both curves. In some people, lateral-bending X-rays are obtained to assess the flexibility of the curves or the primary and compensatory curves.
Congenital and idiopathic scoliosis that develops before the age of 10 is referred to as early-onset scoliosis. Scoliosis that develops after 10 is referred to as adolescent idiopathic scoliosis. Screening adolescents without symptoms for scoliosis is of unclear benefit.
Scoliosis is defined as a three-dimensional deviation in the axis of a person's spine. Most instances, including The Scoliosis Research Society, define scoliosis as a Cobb angle of more than 10° to the right or left as the examiner faces the person, i.e. in the coronal plane.
Scoliosis has been described as a biomechanical deformity, the progression of which depends on asymmetric forces otherwise known as the Hueter-Volkmann Law.
The traditional medical management of scoliosis is complex and is determined by the severity of the curvature and skeletal maturity, which together help predict the likelihood of progression. The conventional options for children and adolescents are:
Treatment for idiopathic scoliosis also depends upon the severity of the curvature, the spine's potential for further growth, and the risk that the curvature will progress. Mild scoliosis (less than 30° deviation) and moderate scoliosis (30–45°) can typically be treated conservatively with bracing in conjunction with scoliosis-specific exercises. Severe curvatures that rapidly progress may require surgery with spinal rod placement and spinal fusion. In all cases, early intervention offers the best results.
A specific type of physical therapy may be useful. Evidence to support their use however is weak. Low quality evidence suggests scoliosis-specific exercises (SSE) may be more effective than electrostimulation.
Bracing is normally done when the person has bone growth remaining and is, in general, implemented to hold the curve and prevent it from progressing to the point where surgery is recommended. In some cases with juveniles, bracing has reduced curves significantly, going from a 40° (of the curve, mentioned in length above) out of the brace to 18° in it. Braces are sometimes prescribed for adults to relieve pain related to scoliosis. Bracing involves fitting the person with a device that covers the torso; in some cases, it extends to the neck. The most commonly used brace is a TLSO, such as a Boston brace, a corset-like appliance that fits from armpits to hips and is custom-made from fiberglass or plastic. It is sometimes worn 22–23 hours a day, depending on the doctor's prescription, and applies pressure on the curves in the spine. The effectiveness of the brace depends on not only brace design and orthotist skill, but also people compliance and amount of wear per day. The typical use of braces is for idiopathic curves that are not grave enough to warrant surgery, but they may also be used to prevent the progression of more severe curves in young children, to buy the child time to grow before performing surgery, which would prevent further growth in the part of the spine affected.
Indications for bracing: people who are still growing who present with Cobb angles less than 20° should be closely monitored. People who are still growing who present with Cobb angles of 20 to 29° should be braced according to the risk of progression by considering age, Cobb angle increase over a six-month period, Risser sign, and clinical presentation. People who are still growing who present with Cobb angles greater than 30° should be braced. However, these are guidelines and not every person will fit into this table. For example, a person who is still growing with a 17° Cobb angle and significant thoracic rotation or flatback could be considered for nighttime bracing. On the opposite end of the growth spectrum, a 29° Cobb angle and a Risser sign three or four might not need to be braced because the potential for progression is reduced. The Scoliosis Research Society's recommendations for bracing include curves progressing to larger than 25°, curves presenting between 30 and 45°, Risser sign 0, 1, or 2 (an X-ray measurement of a pelvic growth area), and less than six months from the onset of menses in girls.
Scoliosis braces are usually comfortable, especially when well designed and well fitted, also after the 7- to 10-day break-in period. A well fitted and functioning scoliosis brace provides comfort when it is supporting the deformity and redirecting the body into a more corrected and normal physiological position.
Surgery is usually recommended by orthopedists for curves with a high likelihood of progression (i.e., greater than 45 to 50° of magnitude), curves that would be cosmetically unacceptable as an adult, curves in people with spina bifida and cerebral palsy that interfere with sitting and care, and curves that affect physiological functions such as breathing.
Surgery is indicated by the Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) at 45 to 50° and by the Scoliosis Research Society (SRS) at a Cobb angle of 45°. SOSORT uses the 45 to 50° threshold as a result of the well-documented, plus or minus 5° measurement error that can occur while measuring Cobb angles.
Surgeons who are specialized in spine surgery perform surgery for scoliosis. To completely straighten a scoliotic spine is usually impossible, but for the most part, significant corrections are achieved.
The two main types of surgery are:
- Anterior fusion: This surgical approach is through an incision at the side of the chest wall.
- Posterior fusion: This surgical approach is through an incision on the back and involves the use of metal instrumentation to correct the curve.
One or both of these surgical procedures may be needed. The surgery may be done in one or two stages and, on average, takes four to eight hours.
A 50-year follow-up study published in the Journal of the American Medical Association (2003) asserted the lifelong physical health, including cardiopulmonary and neurological functions, and mental health of people with idiopathic scoliosis are comparable to those of the general population. Scoliosis that interferes with normal systemic functions is "exceptional" and "rare", and "untreated [scoliosis] people had similar death rates and were just as functional and likely to lead productive lives 50 years after diagnosis as people with normal spines". In an earlier University of Iowa follow-up study, 91 percent of people with idiopathic scoliosis displayed normal pulmonary function, and their life expectancy was 2% less than that of the general population.
Generally, the prognosis of scoliosis depends on the likelihood of progression. The general rules of progression are larger curves carry a higher risk of progression than smaller curves, and thoracic and double primary curves carry a higher risk of progression than single lumbar or thoracolumbar curves. In addition, people not having yet reached skeletal maturity have a higher likelihood of progression (i.e., if the person has not yet completed the adolescent growth spurt).
Scoliosis affects 2–3% of the United States population, which is equivalent to about 5 to 9 million cases. A scoliosis spinal column's curve of 10° or less affects 1.5% to 3% of individuals. The age of onset is usually between 10 years and 15 years (can occur at a younger age) in children and adolescents, making up to 85% of those diagnosed. This is seen to be due to rapid growth spurts occurring at puberty when spinal development is most relenting to genetic and environmental influences. Because female adolescents undergo growth spurts before postural musculoskeletal maturity, scoliosis is more prevalent among females. Although fewer cases are present today using Cobb angle analysis for diagnosis, scoliosis remains a prevailing condition, appearing in otherwise healthy children. Incidence of idiopathic scoliosis (IS) stops after puberty when skeletal maturity is reached, however, further curvature may proceed during late adulthood due to vertebral osteoporosis and weakened musculature.
Since scoliosis was discovered by Hippocrates, physicians and orthopedic surgeons have sought to find a cure for the condition. In the mid-20th century, modern medicine and treatment made decreasing the progression of scoliosis within people and alleviating the pain they experienced possible. This was the result of the progression of scoliosis screenings and treatment. New ways were developed to treat scoliosis because the condition was increasingly understood among medical professionals and orthopedic surgeons. These treatments such as bracing and rod insertion into the spine were made possible at the turn of the 20th century. During this time, many schools subjected their students to physical examinations and posture tests. Students were believed to suffer from negative effects such as poor posture due to hunching over desks for hours in the classroom. Although these screenings were not intended to detect spinal curvature, physicians diagnosed many students with scoliosis. Scoliosis was considered a disease-based condition during the mid-20th century caused by tuberculosis or poliomyelitis. These diseases responsible for causing spinal deformities were successfully managed throughout the 1960s due to the distribution of vaccines and antibiotics. Despite the successful management of diseases causing spinal deformity, many people suffered from scoliosis with no known cause. The unknown cause was eventually determined to be idiopathic scoliosis. Alfred Shands Jr., an orthopedic surgeon, discovered that two percent of diagnosed people had non-disease related scoliosis. Idiopathic scoliosis, also known as the "cancer of orthopedic surgery", was determined to be dangerous because there was no current treatment. The condition needed to be detected in people promptly so treatment could be developed in time to halt its progression. As a result, schools made it mandatory for students to have screenings for scoliosis. Early on, set symptoms could be recognized among the students being tested from ages five to eighteen, but subsequent studies never confirmed them for this age-range. To begin the screenings, children would have their shoulder height, leg length and spinal curvature measurements taken while partially clothed. This was followed with the forward-bend test and bodily comparisons to wall charts that were printed reproductions of the ideal human posture. Unfortunately, these screenings were not always accurate and many students were misdiagnosed because poor posture could often be mistaken for scoliosis. One of the first treatments designed was the Milwaukee brace, a rigid contraption of metal rods attached to a plastic or leather girdle, designed to straighten the spine. As a result of the constant pressure the brace inflicted on a person's' spine, it was particularly painful and inconvenient to wear due to physical limits it imposed. Wearing the brace was known to cause jaw pain, skin irritation, muscle pain and low self-esteem among people.
In 1962, Paul Harrington introduced a metal spinal system of instrumentation that assisted with straightening the spine, as well as holding it rigid while fusion took place. The original (now obsolete) Harrington rod operated on a ratchet system, attached by hooks to the spine at the top and bottom of the curvature that when cranked would distract, or straighten, the curve. The Harrington rod represented a major advance in the field, as it obviated the need for prolonged casting, allowing patients greater mobility in the postoperative period and significantly reducing the quality of life burden of fusion surgery. Additionally, as the first system to apply instrumentation directly to the spine, the Harrington rod was the precursor to most modern spinal instrumentation systems. A major shortcoming of the Harrington method was it failed to produce a posture wherein the skull would be in proper alignment with the pelvis, and it did not address rotational deformity. As a result, unfused parts of the spine would try to compensate for this in the effort to stand up straight. As the person aged, there would be increased wear and tear, early-onset arthritis, disc degeneration, muscular stiffness, and pain with eventual reliance on painkillers, further surgery, inability to work full-time, and disability. "Flatback" became the medical name for a related complication, especially for those who had lumbar scoliosis.
In the 1960s, the gold standard for idiopathic scoliosis was a posterior approach using a single Harrington rod. Post-operative recovery involved bed rest, casts, and braces. Poor results became apparent over time.
In the 1970s, an improved technique was developed using two rods and wires attached at each level of the spine. This segmented instrumentation system allowed patients to become mobile soon after surgery.
In the 1980s, Cotrel-Dubousset instrumentation improved fixation and addressed sagittal imbalance and rotational defects unresolved by the Harrington rod system. This technique used multiple hooks with rods to give stronger fixation in three dimensions, usually eliminating the need for post-operative bracing.
There are links between human spinal morphology, bipedality, and scoliosis which suggest an evolutionary basis for the condition. Scoliosis has not been found in chimpanzees or gorillas. Thus, it has been hypothesized that scoliosis may actually be related to humans' morphological differences from these apes. Other apes have a shorter and less mobile lower spine than humans. Some of the lumbar vertebrae in Pan are "captured", meaning that they are held fast between the ilium bones of the pelvis. Compared to humans, Old World monkeys have far larger erector spinae muscles, which are the muscles which hold the spine steady. These factors make the lumbar spine of most primates less flexible and far less likely to deviate than those of humans. While this may explicitly relate only to lumbar scolioses, it is possible that small imbalances in the lumbar spine could precipitate thoracic problems as well.
Scoliosis may be a byproduct of strong selection for bipedalism. For a bipedal stance, a highly mobile, elongated lower spine is very beneficial. For instance, the human spine takes on an S-shaped curve with lumbar lordosis, which allows for better balance and support of an upright trunk. Selection for bipedality was likely strong enough to justify the maintenance of such a disorder. Bipedality is hypothesized to have emerged for a variety of different reasons, many of which would have certainly conferred fitness advantages. It may increase viewing distance, which can be beneficial in hunting and foraging as well as protection from predators or other humans; it makes long distance travel more efficient for foraging or hunting; and it facilitates terrestrial feeding from grasses, trees, and bushes. Given the many benefits of bipedality which depends on a particularly formed spine, it is likely that selection for bipedalism played a large role in the development of the spine as we see it today, in spite of the potential for "scoliotic deviations". According to the fossil record, scoliosis may have been more prevalent among earlier hominids such as Australopithecus and Homo erectus, when bipedality was first emerging. Their fossils indicate that there may have been selection over time for a slight reduction in lumbar length to what we see today, favoring a spine that could efficiently support bipedality with a lower risk of scoliosis.
Society and culture
The cost of scoliosis involves both monetary losses and lifestyle limitations that increase with severity. Respiratory deficiencies may also arise from thoracic deformities and cause abnormal breathing. This directly affects exercise and work capacity, decreasing the overall quality of life.
In the health care system of the United States, the average hospital cost for cases involving surgical procedures was $30,000 to $60,000 per person in 2010. As of 2006, the cost of bracing has been published as up to $5,000 during rapid growth periods, when braces must be consistently replaced across multiple follow-ups.
Genetic testing for AIS, which became available in 2009 and is still under investigation, attempts to gauge the likelihood of curve progression.

The main purpose of performing CT or MR imaging in a patient with scoliosis is to identify an underlying cause. MR imaging is used with increasing frequency to evaluate patients with an unusual curve pattern or alarming clinical manifestations. Nevertheless, two reasons for performing such screening are plausible: First, the treatment of an underlying neurologic lesion could help alleviate progressive neurologic deterioration and lead to improvement or stabilization of scoliosis; second, surgery performed to correct scoliosis in the presence of an underlying neurologic disorder that has not been identified and treated could result in new or additional neurologic deficits.
