Skeletal abnormalities refer to irregularities in the structure or development of bones. These can occur due to genetic factors, nutritional deficiencies, or environmental influences. Common examples include conditions like osteogenesis imperfecta, which causes fragile bones, and scoliosis, characterized by an abnormal curvature of the spine. These abnormalities can affect individuals of all ages and may lead to pain, mobility issues, or increased risk of fractures. Diagnosis often involves imaging techniques such as X-rays or MRIs, and treatment options may include physical therapy, braces, or surgery, depending on the severity and type of the condition.
