Conservative treatment in spondylolisthesis.

Spondylolisthesis occurs mainly at the L5-S1 interval, thus involving the dynamic segment. The general incidence is between 2 and 5 per cent, but about half of these patients are asymptomatic. The conservative therapy for the asymptomatic patients includes preventive measures such as correction of poor posture, elimination of stressful occupational requirements, avoidance of certain spine movements, and special sport activities. The mild to moderate low back pain syndrome requires alleviation of anxiety, analgesics and muscle relaxants, deep heat and relaxation and range of movement exercises. The severe low back pain which may prevent neurological deficit as well, should include a brief period of bed rest with strong analgesics and then gradual mobilization. In most instances, corsets are not required. Paravertebral blocks may be administered in special recalcitrant cases.
