The anesthetic is injected into the skin and sometimes into the portion of the bone itself where the nerve fibers run. A sedative is given intravenously. A hollow needle is introduced into your body and guided to the area of suspected bone abnormality with the help of a fluoroscope or CT scanner. The site is determined by measuring a specific distance from the hip bone, making a scanner unnecessary. A sample of the synovium, the lining covering bone cartilage, may also be removed.
Bone tissue obtained during the biopsy is sent to a laboratory for analysis.
After the test A pressure bandage is applied to the biopsy site, and you may be asked to lie on the site to apply additional pressure. If the biopsy was performed on the spine, you may have to spend 24 hours in the hospital. You should have someone drive you home, as you may experience some discomfort at the biopsy site. Let your doctor know immediately if you experience bleeding through the bandage or signs of infection such as fever, pain on movement, or redness near the biopsy site. The shape and appearance of bone cells are analyzed under a microscope in order to distinguish benign tumors from cancer.
