The Truth About Back Cracking and Grinding,Deteriorated cartilage surrounding a spinal joint can cause popping, cracking, or grinding. Cartilage may wear down from overuse and/or age, causing the bones of the joint to rub together and produce a grinding sensation and a sound similar to a crack or pop. After a joint is cracked, it can take about 20 minutes for it to be able to crack again.
