What is the difference between kyphotic hunchback and ordinary hunchback?

Generally, the differences between ankylosing kyphosis and common kyphosis lie in their underlying mechanisms, reversibility, and symptoms. The specific details are as follows:

1. Different causes

Ankylosing kyphosis is usually caused by structural bone abnormalities or degenerative spinal diseases. This may include congenital skeletal deformities, osteoporosis, or degenerative spondyloarthropathy. In contrast, common kyphosis results from poor posture or muscular imbalances, without any structural skeletal abnormalities.

2. Different reversibility

Ankylosing kyphosis is typically irreversible because it is associated with structural bone changes or degenerative conditions. This means treatment aims to relieve symptoms and slow progression rather than achieve full correction. Common kyphosis is usually reversible and can be improved through postural correction and muscle-strengthening exercises to restore muscular balance.

3. Different symptoms

Symptoms of ankylosing kyphosis may be more pronounced and severe. There is a significant increase in spinal curvature, leading to back stiffness, pain, and potentially restricted respiratory and physical function. Symptoms of common kyphosis are generally milder, primarily involving forward-tilted shoulders, a prominent upper back, and a sunken lower back, usually without significant functional impairment.

In addition to the above, other differences exist, such as severity and treatment approaches. If a patient has kyphosis, it is recommended to consult a doctor for accurate diagnosis and appropriate treatment advice.
