Today our topic of discussion is Procedure of Bone Biopsy.
Procedure of Bone Biopsy
Procedure (Fig. 29.124)
- Bone biopsies are usually done on an outpatient basis
- The client will be positioned so that the physician can easily reach the bone that is to be sampled.
- A belt or strap may be used to hold you in the correct position .
- If the procedure is performed with CT, you will lie down during the procedure.
- A limited CT scan will be performed to confirm the location to be biopsied .
- You may be connected to monitors that track your heart rate, blood pressure and pulse during the procedure.
- A nurse or technologist may insert an intravenous (IV) line into a vein in the hand or arm so that sedation or relaxation medication may be given intravenously during the procedure.
- You may be also given a mild sedative prior to the biopsy.
- A local anesthesia will be injected to numb the path of the needle.
- A very small nick is made in the skin at the site where the biopsy needle is to be inserted
- Using image-guidance, the physician will insert the needle through the skin; advance it to the bone and then insert a second needle through the first needle, which will remove a small sample of the lesion into its hollow core.
- As the needle being advanced toward the lesion, additional limited CT images may be obtained to monitor the passage of the needle.
- After the sampling, the needle will be removed.
- Pressure will be applied to prevent any bleeding and the opening in the skin is covered with a bandage.
- No sutures are needed. The intravenous line will be removed.
- The client may be taken to an observation area for several hours.
- X-ray(s) or other imaging tests may be performed to monitor for complications
- A needle biopsy is usually completed within 30-60 minutes but may take longer, depending on the size of the biopsied lesion and on the difficulty reaching it with the needle.
After Care

After the procedure, the biopsy site may be sore for up to a week. You should talk to your doctor about pain medication. The client should call your doctor if there is excessive.
