Traumatic intervertebral disc herniation is more common in the cervical spine than in the lumbar spine. Traumatic lumbar disc herniation (LDH) had the same symptoms as degenerative LDH including low‑back pain and nerve root radiculopathy. Many reports are showing that herniated discs can regress spontaneously, therefore, improving neurologic symptoms. The exact mechanism of spontaneous herniated disc regression remains unclear. Traumatic LDH treatment principle should be the same as degenerative LDH. We report a case of traumatic LDH with spontaneous regression and discuss the possible mechanisms of spontaneous lumbar herniation disc regression.
