Scoliosis meaning
Scoliosis is a condition characterized by an abnormal lateral curvature of the spine. It can develop during childhood or adolescence, with the most common form being idiopathic scoliosis, which has no known cause. Other types of scoliosis may result from congenital spinal deformities, neuromuscular conditions, or injuries. Symptoms of scoliosis include uneven shoulders, an asymmetrical waist, and one hip higher than the other. Severe scoliosis can lead to back pain, respiratory issues, and reduced mobility. Treatment options depend on the severity of the curvature and may include observation, bracing, or surgical intervention to correct the spinal alignment and prevent further progression.
