Pelvic Osteosarcoma: Resection and Reconstruction Using a Customised Plate

Introduction Primitive bone tumours of the pelvis represent a considerable challenge for carcinologic surgeons. Resections made in the acetabular zone could disrupt the continuity of the pelvic ring. The morbidity that comes after such a procedure requires a reconstruction surgery in order to improve the functional outcome. In this aim, multiple techniques have been reported. Case report We report the case of a 23-year-old male with no medical history diagnosed with a right pelvic bone osteosarcoma located in Enneking zones I and II. He first underwent neoadjuvant chemotherapy followed by a large resection of the whole bone. A reconstruction was then made using a vascularized fibular autologous graft and stabilized by a long customized lombo-femoral plate. Recovery of walking was possible using crutches. No recurrence was note at one year follow-up. Conclusion Malignant primitive tumours of the pelvis threaten the vital and functional prognoses of patients. It is now possible to perform conservative resections in more than 80% of case without compromising the survival of patients or their functional outcome.
