Kyphosis

• Postural kyphosis is the most common type and is typically seen in adolescents and adults. It results from habitual poor posture rather than structural abnormalities of the spine. The curve is flexible and often improves when the individual consciously straightens their back.
• Scheuermann’s kyphosis is a structural form that usually develops during adolescence. In this condition, several vertebrae become wedge-shaped, creating a rigid and more pronounced curve that does not correct with posture alone. This type often causes pain and stiffness and may worsen with growth.
• Congenital kyphosis is present at birth and results from abnormal vertebral development during fetal growth. Because the spine is structurally malformed, the curve often progresses as the child grows and may require early intervention.
• Degenerative kyphosis occurs later in life due to age-related changes such as disc degeneration, arthritis, and vertebral fractures. Osteoporotic kyphosis, sometimes referred to as a dowager’s hump, is a common example and may progress gradually over time.

There are orthopedic and neurological symptoms. Orthopedic symptoms vary significantly depending on the degree of curvature, its underlying cause, and whether the spine remains flexible or becomes rigid. In mild cases, individuals may notice little more than a rounded posture or forward-leaning head position. Fatigue in the upper back and shoulders is common, especially after prolonged sitting or standing.

As kyphosis progresses, back pain and stiffness may develop, particularly in the thoracic region. Muscle strain occurs as surrounding muscles work harder to support abnormal alignment. Some individuals experience reduced spinal mobility, making it uncomfortable to twist or extend the upper back. In more advanced cases, the curvature can shift overall body alignment, leading to neck pain, lower back discomfort, and difficulty maintaining an upright posture.

Severe kyphosis can affect more than just the spine. Significant curvature may reduce chest expansion, contributing to shortness of breath during activity. In rare cases, pressure on internal organs can lead to digestive discomfort. Neurologic symptoms such as numbness, weakness, or balance issues are uncommon but may occur if spinal nerves are affected.

Neurological symptoms occur when the nerves, spinal cord, or brain are being irritated, compressed, or damaged. When kyphosis is severe, the abnormal curve of the spine can place pressure on nearby nerves or, in rare cases, the spinal cord itself. This pressure can interfere with how nerve signals travel between the brain and the rest of the body.

Neurological symptoms may feel like numbness or tingling, often described as a “pins and needles” sensation, usually in the arms, hands, legs, or feet. Some people notice weakness, such as difficulty gripping objects, trouble lifting the arms, or feeling unsteady when walking. Others may experience clumsiness, balance problems, or a sense that their legs are not responding the way they should.

More serious neurological symptoms can include changes in coordination, frequent stumbling, or difficulty with fine motor tasks like buttoning clothing. In advanced cases, people may notice changes in bladder or bowel control. These symptoms are not typical of mild kyphosis, but when they occur, they are a signal that the spine may be affecting the nerves and should be evaluated promptly by an Ortho Illinois spine specialist.

Kyphosis develops for different reasons depending on age and health status. One of the most common causes is poor postural habits, particularly prolonged slouching during sitting, screen use, or standing. Over time, sustained poor posture can lead to muscular imbalance and increased curvature.\

Structural abnormalities of the vertebrae are another major cause. During growth, some individuals develop wedge-shaped vertebrae that prevent the spine from maintaining normal alignment. Degenerative changes also play a significant role, particularly in older adults. As discs lose height and joints wear down, the spine may gradually collapse forward.

Bone health is a critical factor. Osteoporosis weakens vertebrae, making them vulnerable to compression fractures that increase forward curvature. Trauma, such as spinal fractures from accidents or falls, can also lead to kyphosis. Less commonly, infections, tumors, inflammatory conditions, or prior spinal surgery may disrupt spinal structure and alignment.

Diagnosing kyphosis begins with a detailed medical history and physical examination. An Ortho Illinois spine specialist evaluates posture, spinal alignment, and range of motion while observing the spine from multiple angles. The flexibility of the curve is assessed to help determine whether the condition is postural or structural.

Imaging plays a central role in diagnosis. X-rays are used to confirm the presence of kyphosis and measure the degree of curvature. These measurements help guide treatment decisions and monitor progression over time. Advanced imaging such as MRI or CT scans may be ordered if there are neurologic symptoms, suspected fractures, or concerns about the spinal cord, discs, or surrounding tissues. Early and accurate diagnosis is essential to prevent progression and identify underlying conditions that may require targeted treatment.
