Low back pain (LBP) is a common disorder in orthopedic outpatients, affecting people of all ages, and some patients may develop chronic LBP. As a complex organelle, mitochondria are not only energy workstations but also regulate cell senescence, apoptosis, and homeostasis. Mitochondrial dysfunction promotes disk degeneration by affecting a variety of pathophysiological processes, including oxidative stress, mitophagy, mitochondrial homeostasis, cellular senescence, and cell death. We review the molecular mechanisms underlying the relationship between mitochondrial dysfunction and intervertebral disk degeneration (IDD) to provide a theoretical basis for IDD treatment using pharmacological or tissue-engineering approaches.
