Scoliosis: What Should You Check When the Back Appears Curved to One Side?

Scoliosis is a condition in which the spine curves sideways with accompanying vertebral rotation. The curvature angle (Cobb angle) is measured on standing spine X-rays, and curvature of 10 degrees or more is generally considered scoliosis. Idiopathic scoliosis, where the cause is unknown, is the most common form and is frequently discovered in growing adolescents.

Slight differences in shoulder or pelvic height alone do not confirm scoliosis. Conversely, scoliosis can progress even when not visually obvious on the outside, making imaging confirmation essential whenever suspected.

• One shoulder or shoulder blade appears higher or more prominent
• Pelvic heights differ and waistline curves look uneven left to right
• The back appears curved sideways when viewed from behind
• When bending forward 90 degrees at the waist, one side of the back or lower back appears higher
• Backpack straps or undergarment straps slip off only one shoulder

These items are references to help judge whether an evaluation is warranted; actual angles and diagnosis are confirmed by imaging examinations.

During periods of rapid height growth, curvature angles can increase quickly. If scoliosis is suspected in growing children or adolescents, it is important to confirm the angle and growth stage via X-rays at orthopedics or relevant clinics and track changes periodically.

Depending on the angle and growth status, clinical observation, bracing, or rarely surgery is considered. Such decisions must be made in collaboration with the relevant medical specialty based on imaging and growth evaluations. Seek prompt medical evaluation if back pain worsens at night or is accompanied by fever, if leg numbness, muscle weakness, or gait changes develop, if bowel or bladder control changes, if deformity progresses rapidly, or if shortness of breath occurs. Scoliosis presenting with such symptoms may not be idiopathic scoliosis and requires further investigation.

When scoliosis is accompanied by upper or lower back pain, muscle tension, or restricted movement, a Korean medicine clinic can evaluate pain and functional limitations. A Korean medicine doctor checks the painful area, posture, trunk rotation and forward bending range, tension and strength in spinal musculature, and reviews existing imaging results.

If red flags are absent, Chuna manual therapy, acupuncture, and pharmacopuncture may be considered according to the patient's condition to help manage pain and mobility. However, because evidence that Chuna manual therapy straightens the curved spinal angle itself is insufficient, managing curvature angles in growing children follows periodic imaging tracking and guidance from the treating orthopedic specialty. In growing children, treatment proceeds with gentle intensity after verifying physical examination and imaging findings.

Evidence is lacking to assert that a single specific posture causes idiopathic scoliosis or that carrying heavy bags causes the curvature. Nevertheless, modifying habits such as chronically leaning to one side or carrying bags on only one shoulder is advisable for pain management.

Exercises that comprehensively incorporate trunk muscle strength, flexibility, and breathing can aid pain and functional management. Responses to exercise and treatment are monitored through pain and activity levels, while angle changes are confirmed according to the imaging tracking schedule set by the responsible medical department.
