A ruptured disk in the back occurs when all or part of a vertebral disk is forced through the bones of the spinal column.
The vertebrae of the spinal column are separated by vertebral disks that act like shock absorbers. A disk is made up of two parts. The outer ring or annulus is a tough, fibrous material. The inner part or nucleus is a soft, jelly-like material. A ruptured disk occurs when the outer ring tears or breaks, allowing the jelly-like material to poke through the crack. The disk may press on nerves, causing pain and loss of function.
There are many causes of a ruptured disk. Repeated heavy lifting is the most common cause, especially when improper lifting techniques are used. Many people who have a ruptured disk are involved in manual labor jobs. Other risk factors for disk rupture include:
The location of the ruptured disk determines where a person will have symptoms. Most ruptured disks are in the lower back and cause low back pain. The ruptured disk may press on the sciatic nerve. This pressure causes sciatic nerve dysfunction. The person may experience the following symptoms:
If the ruptured disk is in the upper back, the symptoms may be in the shoulder, arm, or hand.
Diagnosis of a ruptured disk begins with a medical history and physical exam. Depending on the suspected cause of the problem, the provider may order diagnostic tests, such as:
Proper lifting techniques are important to avoid a ruptured disk. These techniques can be enhanced by the use of an abdominal support belt. Other preventive measures include the following:
Chronic pain from an untreated ruptured disk can result in depression, lack of productivity, and drug abuse. If the ruptured disk presses on a nerve, the person may have weakness, numbness, and loss of muscle mass.
A ruptured disk is not contagious and poses no risks to others.
A ruptured disk is generally treated conservatively at first. Initial treatments include:
If conservative treatment is not successful, the healthcare provider may recommend surgery. The following operations may be helpful for people with a ruptured disk:
Side effects of medicines include allergic reactions and stomach upset. Surgery is associated with a risk of infection, bleeding, and allergic reaction to anesthesia.
After conservative treatment of a ruptured disk, a person can usually resume activity as tolerated. Symptoms may recur every now and then, requiring repeated treatment. Ninety percent of the time, surgery relieves symptoms, and the person can slowly resume normal activities. Physical therapy can be helpful to teach appropriate body mechanics and lifting techniques.
Any new or worsening symptoms should be reported to the healthcare provider.
