A bone lesion biopsy is a surgery in which a surgeon removes a bone marrow sample for lab testing, according to MedlinePlus. It helps doctors distinguish cancerous bone tumors from noncancerous ones. Doctors also apply bone lesion biopsy in diagnosis of other disorders that affect the bones. Depending on the size of the sample a surgeon intends to remove, either local or general anesthesia are necessary during the procedure.
To prepare for a bone lesion biopsy, a doctor may advise a patient to stop ingesting any food as this may affect the procedure, says MedlinePlus. During bone lesion biopsy, the surgeon starts by administering anesthesia to the patient before cutting an incision through the skin to access the bone. He drills a special needle into the bone and obtains a bone marrow sample from the bone lesion. He removes the drill needle, presses against the incision to stop bleeding, and closes the incision with stitches. Applying a bandage over the site and taking the sample to a laboratory for analysis completes the process.
Though a useful procedure, bone lesion biopsy may cause bone infection. Other complications include infection in the area adjacent to the surgery site, bone fracture, and damage to the tissue that surrounds the area, states MedlinePlus. Patients who have had bone lesion biopsies may also bleed excessively.
