A type of drug used to treat weak bones is associated with an increased risk of 'micro-cracks' in bone, according to new research.
The early-stage research, by scientists at Imperial College London, suggests these microcracks may reduce mechanical strength of the bone.
In the study, published in the journal Scientific Reports, researchers studied bone samples from 16 people who had been diagnosed with the weak bone condition osteoporosis.
All of the patients had suffered a broken hip, and half of the patients had been taking a type of commonly-prescribed drug called bisphosphonate.
