Fixation of Pubic and Acetabular Pathologic Fracture with Curvafix Nail and Concurrent Total Hip Arthroplasty: A Case Report.

Abstract

Introduction: The pelvis is one of the most common sites for metastatic spread to bone. Ensuing pathologic fractures pose major issues to patients. Fixation becomes essential to decrease pain and allow for weight-bearing. However, the pelvis poses a unique challenge as there are certain portions like the pubis that, because of their natural curve, are not amenable to plate or screw fixation.

Case report: A 76-year-old female with known bone metastases presented to clinic with right hip pain. Computed tomography (CT) of the chest, abdomen, and pelvis revealed a new lesion in the lateral superior ramus involving the medial acetabulum. She also had osteoarthritis of the hip, for which she had an upcoming total hip arthroplasty scheduled. We performed intramedullary fixation of the lesion in the lateral superior ramus with a Curvafix nail concurrently with total hip arthroplasty.

Conclusion: This case report demonstrates the utilization of a Curvafix nail in the oncologic context of an anterior column acetabular fracture along with a concurrent ipsilateral total hip arthroplasty.
