herniated disc; slipped disc

Displacement of part of the gelatinous interior of an intervertebral disc so that it protrudes through the fibrous outer coat. The exuded disc material may press against adjacent nerves and cause severe pain. So-called slipped discs preclude physical activity but, once the patient has recovered, exercises are often used to strengthen the abdominal and back muscles in order to reduce the risk of a recurrence of the prolapse. See also sciatica.

herniated disc; slipped disc

Displacement of part of the gelatinous interior of an intervertebral disc so that it protrudes through the fibrous coat pressing on adjacent nerves. It is usually caused by a combination of disc degeneration over a long period of time and a physical trauma sustained during a single event. The lumbar region is the most commonly affected part of the backbone because it is subjected so frequently to enormous loads. Symptoms include pain in the buttocks and legs, with the pain worsening when coughing and straining. Initial treatment may include icing the back (during the first 48-72 h; see ice treatment), rest in bed with the knees bent, and application of a heat pad to reduce muscle spasms. A doctor may prescribe long-term rest (8-12 weeks), anti-inflammatories, cortisone injections, and, for persistent problems or in an emergency situation, surgical correction. Once the pain has dissipated and the disc is healed, rehabilitation includes exercises that strengthen the abdominal and back muscles in order to reduce a recurrence of the prolapse.
