Today our topic of discussion is Bone Biopsy.

Bone Biopsy
Bone biopsy uses a needle and imaging guidance to remove a small sample of bone for examination under a microscope. Bone biopsies may be used to confirm the diagnosis of a bone disorder, investigate an abnormality, determine the cause of pain or infection, or distinguish bone tumor from other conditions.
Needle biopsy is less invasive than surgical biopsy and may not require general anesthesia (Fig. 29.122).A bone biopsy is a procedure in which bone samples are removed (with a special biopsy needle or during surgery) to find out if cancer or other abnormal cells are present.
A bone biopsy involves the outer layers of bone, unlike a bone marrow biopsy, which involves the innermost part of the bone.Your doctor takes the biopsy once you are asleep. Your doctor injects local anaesthetic into the area. This means the area is numb and it shouldn’t be painful. You may also have a drug to make you drowsy and more relaxed (sedation).
The doctor makes a small cut in the skin over the bone. Then the doctor places the needle into the bone to take out the sample. They use a very thin one in a fine needle biopsy to remove a small sample of cells or tissue. They will use a larger one to get a bigger piece of bone in a core needle biopsy.
Indications
- Bone biopsies are performed to: Confirm the diagnosis of a bone disorder
- Investigate an abnormal area, or lesion, seen on X-ray, bone scan, CT or MRI
- Distinguish bone tumor from other conditions, such an infection
- Distinguish whether a tumor is benign or cancerous
- Determine the cause of an infection or inflammation
- Identify the cause of bone pain.
