title: Acetabulum malignancies: technique and impact on pain of percutaneous injection of acrylic surgical cement.
abstract: The aim of our study was to describe the technique of percutaneous injection of acrylic surgical cement into acetabulum malignancies [percutaneous acetabuloplasty (PCA)] and determine its efficiency in relieving pain. Eighteen patients (8 men, 10 women; aged 40-81 years) with painful acetabular malignancies (18 lesions; 17 metastases, 1 multifocal bone sarcoma) were treated with PCA. Procedures were done using lateral approach with fluoroscopic guidance. The 18 procedures were evaluated and resulted in 4 (22 %) total improvement, 7 (39 %) clear improvement, 4 (22 %) moderate improvement, 1 (6 %) no improvement, and 2 (11 %) worsening in keeping with a cement leak in contact with the sciatic nerve and a leak towards the joint. Follow-up ranged from 2 to 48 months (average 9.4 months). We observed 2 cases of recurrence of pain at 6 and 39 months, both in keeping with local tumoral progression. PCA of malignancies is a minimally invasive and low-cost procedure that provides immediate and long-term pain relief.
