PURPOSE: Screw fixation (osteosynthesis) can be performed percutaneously by interventional radiologists. We report our experience in @entity5 @entity1 . MATERIAL/METHODS: We retrospectively reviewed all cases of percutaneous osteosynthesis (PO) of the pelvic ring and proximal femur performed in our hospital. PO were performed for @entity174 palliation or for osteolytic metastases consolidation. Screws were inserted under CT- or cone-beam CT- guidance and general anaesthesia. @entity1 were followed-up with pelvic-CT and medical consultation at 1  month, then every 3  months. For @entity174 , the goal was @entity158 palliation and for osteolytic metastases, pathologic @entity174 prevention. RESULTS: Between February 2010 and August 2014, 64 @entity5 @entity1 were treated with PO. Twenty-one @entity1 had PO alone for 33 painful @entity174 (13 bone-insufficiency, 20 pathologic @entity174 ). The @entity158 was significantly improved at 1  month (VAS score   =   20/100 vs. 80/100). In addition, 43 @entity5 @entity1 were preventively consolidated using PO plus cementoplasty for 45 impending pathologic @entity174 (10 iliac crests, 35 proximal femurs). For the iliac crests, no @entity174 occurred (median-FU   =   75  days). For the proximal femurs, 2 pathological @entity174 occurred ( @entity174 rate   =   5.7  %, median-FU   =   205  days). CONCLUSION: PO is a new tool in the therapeutic arsenal of interventional radiologists for @entity158 management. KEY POINTS:     Screw fixation (osteosynthesis) can be performed percutaneously by interventional radiologists.     CT- or CBCT-guidance results in high technical success rates for screw placement.     This minimally invasive technique avoids extensive surgical exposure in @entity3478 @entity1 .     Osteosynthesis provides @entity158 relief for @entity174 .     Osteosynthesis plus cementoplasty provide prophylactic consolidation of impending pathological @entity174 .
