How to perform percutaneous bone cement implantation for bone metastasis

Percutaneous bone cement implantation is a minimally invasive treatment technology developed in the past 20 years for the treatment of bone cancer caused by bone metastasis of malignant tumors. The method is to use a bone puncture needle to directly puncture the skin under fluoroscopy or CT monitoring, reach the vertebral lesion through the pedicle, and inject bone cement.

Percutaneous bone cement implantation can help bone cancer patients quickly relieve pain, with an immediate pain relief rate of 75% to 94%. The thermal effect and toxicity of bone cement help kill tumor cells, and can also stabilize and strengthen the vertebral body, restore the strength and hardness of the vertebral body, prevent further collapse of the vertebral body, and even restore part of the vertebral height.

Compared with other treatments for bone metastasis, such as surgery and radiotherapy, percutaneous bone cement implantation is minimally invasive, has significant analgesic effects, and has few complications. It can also kill tumors and stabilize the spine. However, although percutaneous bone cement implantation is less invasive, routine preoperative examinations are required. After surgery, the patient's pain improvement needs to be observed, the recovery of neurological function needs to be evaluated, and further treatment plans need to be developed for the primary tumor. Outpatient treatment lacks monitoring facilities, so it is recommended that patients be hospitalized for treatment.

Percutaneous bone cement implantation is not suitable for patients with bone cancer and infectious diseases such as vertebral tuberculosis, suppuration, or infection around the puncture site, as well as patients with cardiopulmonary, liver, and kidney failure or coma.
