What Causes Spinal Infections?

Spinal infections may occur following surgery or spontaneously in patients with certain risk factors. Risk factors for spinal infections include poor nutrition, immune suppression, human immunodeficiency virus (HIV) infection, cancer, diabetes and obesity.

What Are The Symptoms of Spinal Infections?

The symptoms of a spinal infection include fever, chills, headache, neck stiffness, pain, wound redness and tenderness, and wound drainage. In some cases, patients may notice new weakness, numbness or tingling sensations in the arms and/or legs. The symptoms may be very severe, or they may be very subtle in some cases.

What Are The Treatment Options For Spinal Infections?

Nonsurgical Treatment

The nonsurgical medical and interventional management of spinal infections consists of antibiotic or anti-fungal medications. The type and the duration of the treatment depends on the severity of the infection and the organism causing the infection.

Antibiotics or antifungal medications may be necessary intravenously (IV) and/ or orally. The duration of the treatment typically ranges from as short as 7-10 days, to as long as 6-12 weeks.

You may need to have a special intravenous line, called a central line, placed for a long course of antibiotics. This allows, in some cases, for the medications to be administered at home with the assistance of a home health care agency or a visiting nurse. Your doctor may recommend using a brace to support the spine until healing occurs and to help with the pain.

Surgical Treatment

Surgery may be required for many postoperative infections to wash away much of the bacteria and infected tissue. In addition, surgery may be required in cases where there is evidence of instability of the spine as a result of the infection. In cases in which there is severe weakness as a result of a spinal infection, surgery may be required to relieve the pressure on the spinal cord caused by the infection. What are the surgical options?

The surgical options to treat spinal infections range from simply washing out the wound and re-closing  debridements  of infected tissues.

In some cases it is not possible to close the wound at the time of surgery, and a packing dressing is left in place. This is often changed two to three times a day until the wound heals over a period of several weeks.
