Bone lesion biopsy
Alternative names:
biopsy - bone; bone biopsy
How the test is performed:
A bone biopsy involves removal of a small piece of bone for examination. A special drill needle is usually used. A local anesthetic is given, 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 as a surgical excision (cutting out) of a piece of bone. Excision provides a larger specimen and permits 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 it is to be performed under general anesthesia, fasting for 6 to 8 hours is recommended. You must sign a consent form.
Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:
How the test will feel:
You may feel moderate discomfort and pressure, even though a local anesthetic is used for a needle biopsy. You must remain still during the procedure.
After the biopsy, the area may be sore or tender for several days.
Why the test is performed:
The most common reasons for bone lesion biopsy are to distinguish between benign and malignant bone tumors, and to identify other bone abnormalities. It may be performed on people with bone pain and tenderness, particularly if X-ray, CT scan, or other testing reveals a mass (aggregation of cells) or abnormality.
