Giant cell tumor of the pelvis and sacrum: 17 cases and analysis of the literature.

The optimal treatment of giant cell tumors of the pelvis and sacrum is controversial. Our current patient series was combined with cases identified in a review of the literature published in the past 50 years, yielding a combined group of 239 lesions for study. Recurrence rates were 49% for patients who had radiation therapy alone, 47% for patients who had surgery with intralesional margins, 46% for patients who had surgery with intralesional margins and radiation therapy, and 0% for patients who had surgery with wide margins.

Pelvic fractures in pregnancy: factors influencing maternal and fetal outcomes.

Background: The purpose of this study was to determine factors influencing maternal and fetal outcomes associated with pelvic fractures in pregnancy.

Methods: A literature review of pelvic and acetabular fractures during pregnancy was performed, providing 101 cases for analysis (1 case report was included). Factors influencing maternal and fetal mortality were evaluated.

Inadvertent sacral bar transfixation of the cauda equina.

We present a case of inadvertent sacral bar transfixation of the cauda equina as a complication of posterior pelvic internal fixation. The "safe zone" for sacral bar placement is narrow, especially in the presence of fracture displacement. This complication can be avoided by achieving fracture reduction before internal fixation.
