Why does spondylolisthesis cause lower back pain?

Spondylolisthesis occurs when one vertebra shifts in relation to the vertebra beside it. The change can place extra load on the small joints, discs, ligaments, and muscles that support the lower spine. These tissues may become irritated during bending, lifting, standing, or repeated movement, leading to aching, stiffness, or pain in the lower back.

The amount of movement and the symptoms do not always match. Some people have a spinal shift with few symptoms, while others feel pain during particular activities. If the shifted segment narrows a nerve passage, leg pain, tingling, numbness, or weakness may occur as well. An examination helps separate these patterns from other causes of back pain.

A clinician can review your history and examine spinal movement, hip movement, strength, sensation, reflexes, and walking. Treatment may include physiotherapy to improve trunk and hip control, flexible movement, and lifting technique. Pacing activities, changing position regularly, and avoiding movements that repeatedly trigger sharp pain can reduce strain while you build tolerance. Follow advice about medicines or imaging if they are recommended for your situation.

Seek urgent help for new or worsening leg weakness, difficulty walking, numbness around the inner thighs or genitals, or loss of bladder or bowel control. Arrange prompt review after significant injury, or if pain is severe and accompanied by fever or rapidly changing symptoms.

Ask which spinal level is involved, whether the segment appears stable, which movements to practise or limit, and how strength and walking will be followed. Ask what symptoms would require urgent reassessment.
