Minimally Invasive Fixation of Pelvic Metastases by CT-Assisted Surgical Navigation.

The treatment of patients with painful metastases and pathologic fracture of the pelvis is challenging and based on multidisciplinary approach. Although radiation and disease-specific systemic therapy are the mainstay of treatment, the goal of surgery is to maintain functional independence. Harrington-type total hip arthroplasty has proven invaluable to address periacetabular cancer. However, data on how to best treat patients with disabling pain due to metastases outside the periacetabular region or involving the entire hemipelvis are scant, heterogeneous, and hardly comparable. Minimally invasive strategies in this setting are appealing and conceivably preferable to open surgery because of lower risk of complications and expedited recovery.
