Navigation-guided percutaneous pelvic cementoplasty for metastatic bone pain

Abstract

Abstract Rationale: Percutaneous cementoplasty is a minimally invasive procedure that can provide immediate pain relief and improve range of motion in patients with metastatic bone pain. Conventionally, this procedure is guided by computed tomography (CT). However, to minimize exposure to radiation, we performed percutaneous cementoplasty under the guidance of a navigation system. Patient concerns: A 60-year-old man presented with left hip pain for several months due to bone metastasis in the left ilium. Diagnoses: The patient was diagnosed with lung cancer and multiple bone metastases including ileum. Interventions: The puncture needle was placed under the guidance of a navigation system with pre-procedure CT images, and bone cement was injected into the osteolytic lesion in the left ilium. Outcomes: Bone cement placement was confirmed by post-procedure radiography, and its distribution was satisfactory. The patient s Karnofsky Performance Scale and Brief Pain Inventory scores showed improvement in pain and mobility without complications. Lessons: Percutaneous cementoplasty guided by a navigation system is a safer and more effective method with less radiation compared with conventional CT-guided methods.
