Study of treatment using percutaneous acetabuloplasty and interstitial implantation of 125I seeds for patients with metastatic periacetabular tumors

Background The periacetabular area is one of the primary sites of metastatic tumors, which often present as osteolytic bone destruction. Bone destruction in the acetabulum caused by metastatic tumors will cause hip pain and joint dysfunction. It results in decreased quality of life for patients. The aim of our study was to explore the clinical effect of metastatic periacetabular tumors treated with percutaneous cementoplasty and interstitial implantation of 125I seeds.
