Is back cracking harmful? Is scoliosis correlated with back cracking?

Cracking. Joint cracking is most commonly due to benign pressure changes in the joints. Rarely, instability of the spine can cause popping. There is no correlation with scoliosis and it is rarely harmful. For more information visit under scoliosis.
No,no. Scoliosis is usually not, in and of itself, associated with back cracking. It is felt to be a similar phenomenon to cracking your knuckles. Instead of the knuckles, the joints involved are thought to be the facet joints located in the posterior part of the spine. Thank you for your question.
