Weak ligaments : The sacroiliac ligament and iliolumbar ligaments help to hold the lower back together. Due to its poor blood supply it is hard to heal. Prolotherapy can help to fix that area quicker.

Joint pressure: Just like your fingers crack, joints in your back can pop due to increased pressure. Old injuries can make this happen more often.
