A normal spine, when viewed from the back, appears straight. In contrast, kyphosis is characterized by an excessive forward curvature of the upper back (thoracic spine), resulting in a rounded or “humpback” appearance. This condition affects the alignment of the vertebrae and can vary in severity, ranging from mild rounding to a more pronounced curve.
The spine consists of three segments with natural curves: the cervical spine (neck), thoracic spine (chest), and lumbar spine (lower back). When viewed from the side, the cervical and lumbar regions form forward C-shaped curves, known as lordosis, while the thoracic spine forms a reverse C-shaped curve called kyphosis. These natural spinal curves are vital for our balance, helping us stand upright and absorb shock as we move. However, if these curves become exaggerated or flattened, it can disrupt posture and make it challenging to maintain an upright stance. The spine is made up of 24 vertebrae, small rectangular bones stacked together. Between each vertebra is an intervertebral disk, which cushions the vertebrae and absorbs shock, helping with movement and flexibility.
Kyphosis can be classified into postural, Scheuermann’s, and congenital types. Postural kyphosis, often linked to poor posture, involves a curvature exceeding 50 degrees but remains flexible and responsive to corrective exercises. Scheuermann’s kyphosis, more rigid in nature, stems from wedge-shaped vertebrae and tends to progress during growth spurts. Congenital kyphosis arises from vertebral malformations present at birth, leading to an outward spinal curve that becomes more apparent as the child grows.
The causes of kyphosis include congenital conditions present at birth and acquired factors like metabolic issues, neuromuscular disorders, or osteogenesis imperfecta, a brittle bone disease causing fractures. Spina bifida can also lead to kyphosis. Scheuermann’s kyphosis, with an unknown cause, results in a forward curve of the vertebrae, mostly in males. Postural kyphosis, linked to slouching rather than structural issues, is the most common form and often seen in adolescents, which can improve with targeted exercises.
The treatment for kyphosis involves an assessment of several factors such as the child’s age, remaining growth potential, the severity of the curvature, and whether back pain is present are carefully evaluated. Kyphosis treatment focuses on alleviating symptoms and addressing specific concerns. For pain management, exercises to strengthen the core muscles and medications are commonly recommended. For those primarily worried about the appearance of the curvature, options like bracing or targeted postural exercises can help improve alignment and confidence.
