It most commonly develops between the ages of ten and twenty. Females typically are more severely affected than males with a ratio of 4:1. 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, ribs and buttock pain nearest the bottom of the back
Respiratory or cardiac problems in severe cases
Constipation due to curvature causing "tightening" of the stomach, intestines, etc. Limited mobility secondary to pain or functional limitation in adults mostly when twisting the torso.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
Uneven posture
Heart and lung problems in severe cases
Calcium deposits in the cartilage endplate and sometimes in the disc itself

Course
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.
Progressive idiopathic early-onset scoliosis can be a life-threatening condition with negative effects on pulmonary function. Scoliosis that develops after 10 is referred to as adolescent idiopathic scoliosis. Screening adolescents without symptoms for scoliosis is of unclear benefit. Definition
Scoliosis is defined as a three-dimensional deviation in the axis of a persons 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. Management
Scoliosis curves do not straighten out on their own. Many children have slight curves that do not need treatment. In these cases, the children grow up to lead normal body posture by itself, even though their small curves never go away. If the patient has a larger curve and they are still growing, it is important to monitor the curve for change by periodic examination and standing x-rays as needed. The rise in spinal abnormalities require examination by an orthopaedic surgeon to determine if active treatment is needed.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:
Observation
Bracing
Surgery
Physical Therapy.
