Introduction And Importance: Chondrosarcomas are the third most frequent malignant bone tumors. With pelvic bones being their most common primary location, diagnosis and treatment of these tumors is especially challenging due to the diverse clinical manifestations and involvement of critical anatomic structures. We present the case of a grade III pelvic chondrosarcoma of the left iliopubic branch managed through a multidisciplinary approach.

Introduction: chondrosarcoma is the second most common primary malignant tumor, constitutes approximately one quarter of all primary bone sarcomas.

Case: There is an increasing emphasis on adverse reactions to metal debris around prosthetic hip implants. We present a case report of a patient with increasing pain around a previous total hip arthroplasty and magnetic resonance imaging findings consistent with a pseudotumor. Serum metal ion levels were not elevated and initial biopsy findings inconclusive.

Background And Objectives: Recent studies have reported acceptable outcomes after arthrodesis takedown and conversion to total hip arthroplasty (THA); however, there are no reports on outcomes after oncologic resection, which are inherently complex and may portend poorer outcomes. The purpose of this study was to examine the surgical and functional outcomes of patients who underwent prior hemipelvectomy for tumor resection and were later converted to THA.
Methods: All patients who had prior iliofemoral arthrodesis after oncologic resection that were later converted to THA at a single institution were examined.
