"Fragile" means the bones can't withstand the normal stresses of daily life. They are more likely to be damaged or break with simple activities.

Fragile bones can occur for a variety of reasons. Anything that alters the formation of bone can affect bone structure and strength. Causes include diabetes, thyroid conditions, gastrointestinal problems, and cancer. Certain medications also interfere with bone, such as steroids, blood thinners, or anticonvulsants for seizures.

Osteoporosis is sometimes referred to as "fragile bones." This is the loss of bone mass that occurs in many women after menopause. Ask your doctor to explain the meaning of "fragile bones" in your case. Treatment and prevention of further problems depend on a specific diagnosis.
