AIM: The goal of this study was to specifically address the incidence of dorsal leakage when performing vertebroplasty in @entity1 with posterior wall @entity3061 or @entity174 , by using a delayed injection of cement with the aim of increasing its viscosity. MATERIALS AND METHODS: We prospectively reviewed the records of 24 @entity1 (13 @entity1 , 11 @entity1 ; age range 42-67  years; mean age 54.7) with diagnosis of @entity1582 ( @entity1582 ) who underwent 34 vertebroplasties between January 2007 and January 2010 for @entity158 osteolytic localization of @entity1582 with dorsal cortical @entity3061 or @entity174 . All vertebroplasties were performed with an 8  min delay, which was half of the allotted injecting time given for the chosen cement. In 11 cases there were @entity174 involving the posterior wall, in 1 case with @entity1949 , and in 33 cases there was dorsal cortical @entity3061 . All of the @entity1 showed no response to standard treatments such as radiotherapy, chemotherapy, and analgesic treatments. RESULTS: Technical success was achieved in all cases. In 20 @entity1 , we treated only one high-risk @entity75 , in six @entity1 we treated two segments, and in one @entity1 we treated three segments. All @entity1 experienced improvement in symptoms after the procedure as demonstrated by improved visual analogue scores (VAS) and performance status (PS) and decreased doses of analgesic. There was a dorsal leakage in 2/34 (5.8%) treated vertebral bodies in which an epidural space @entity5 extension was also diagnosed, without increasing neurological symptoms after the intervention. CONCLUSION: From these results vertebroplasty with delayed injection of cement is safe and effective in the treatment of vertebral localization of @entity1582 with @entity3061 or @entity174 of the posterior vertebral wall.
