Osteomalacia is an abnormal change in bone mass that is not normal, no matter what age it occurs. As people age, their bones degenerate and age, resulting in hyperplasia. It is commonly accepted by the general public that when older people develop bone growth, they feel that it is normal to develop growth when their bones are bad. If a person in his or her 20s develops bone growth, it is certainly not normal according to the conventional rules. For people in their 20s who develop bone growth, common causes include trauma, abnormal bone metabolism, and diseases of the bone, all of which can lead to bone growth, especially those caused by trauma are most common. Therefore, osteomalacia itself is an abnormal change, and it is not normal no matter what age it appears. However, the appearance of osteophytes in the elderly is inevitable and slowly accepted, but the premature appearance of osteophytes in young people is not generally accepted and is considered abnormal.
