Medical Research: What is the background for this study? What are the main findings?
Response: Jerome Fryer, one of our co-authors, had a new idea for why joints crack. So before delving into this, we went to go to the scientific literature to see if there was anything new in this topic area since it was first studied seriously in 1947. To our surprise, nothing had really been changed in this topic since 1971. It was then we realized there was a real opportunity to use some new technology to see inside the joint in a way that has never been done before. What we saw was that at the same time the sound is produced, a gas cavity appears. We can’t know for certain that this is the cause of the sound, but it is consistent with what was proposed originally in 1947.
Medical Research: What should clinicians and patients take away from your report? Is there damage to the joints from ‘cracking’ them?
Response: No. We have known for quite some time from other studies that people who do this habitually do not experience premature joint problems.
