Bone lesion biopsy
Definition:
A bone lesion biopsy is a test in which a piece of bone or bone marrow is removed for examination. Alternative Names:
Bone biopsy; Biopsy - bone Text Continues Below
How the test is performed:
A bone lesion biopsy involves removal of a small piece of bone for examination. A special drill needle is usually used. A local anesthetic is given (to numb the area, the patient remains conscious), a small (about 1/8 inch) incision is made in the skin and the biopsy needle is pushed and twisted into the bone. Once the sample is obtained, the needle is twisted out and the sample is sent for examination. Pressure is applied to the site. Once bleeding stops, the site is cleaned and covered with a bandage. Bone biopsy may also be performed under general anesthesia for surgical excision (cutting out) of a piece of bone. Excision provides a larger specimen and may permit immediate surgical removal if examination indicates a malignant (cancerous) tumor. How to prepare for the test:
You may be asked to fast before a bone biopsy. If the procedure will be performed using general anesthesia, fasting for 6 to 8 hours is usually required. You must sign a consent form. For infants and children: The preparation you can provide for this test depends on your child's age and experience. For specific information regarding how you can prepare your child, see the following topics: How the test will feel:
With a needle biopsy, you may feel moderate discomfort and pressure, even though a local anesthetic is used. You must remain still during the procedure.
