This type of fracture deals with a break in the bone that occurs because of bone disease or a change surrounding the bone tissue that makes the bone weak.

Spontaneous fracture.

Explanation:

Spontaneous fractures occur when there is a disease that significantly weakens the bone structure, ie this type of fracture occurs due to a bone rupture that occurred due to a bone disease or a change around bone tissue that weakened the bone.

Among the most common causes of weakness are osteoporosis (calcium deficiency and corticosteroid-induced), bone malignancy or metastasis, Paget's disease (bone tuberculosis), vitamin A overexposure, periprosthetic weakness, osteomyelitis, brucellosis, cerebral palsy (especially in children) and osteoarthritis due to chronic renal failure.
