A new spin on life: 3D imaging in the treatment of paediatric osteosarcoma

Abstract

Osteosarcoma is a malignant or benign bone tumour that can occur at any age but typically peaks at adolescence, coinciding with rapid bone growth. It characteristically occurs at the end of long bones, affecting the joint and the functionality of the limb with the potential for metastases.1 Historically, patients with this condition had a poor prognosis. This is partly due to the potential for tumour cells to remain post-surgery or conversely more bone than necessary may have been removed.2 These two factors were primarily due to the inability to conclusively delineate the margins of tumours at the time of resection. Today, with the innovation of new technology (Siemens/Brainlab), the Queensland Children's Hospital is the first paediatric site in Australia to have a dedicated and permanent 3D imaging navigation system. The mobile C-arm fluoroscopy system (Siemens CIOS Spin) is enabling the paediatric Orthopaedic oncology team to surgically resect osteosarcomas with pinpoint accuracy.3 The presentation will review the implementation of this visionary equipment, including the multidisciplinary team approach. This has resulted in the best possible surgical and overall outcomes for a patient group which previously did not have a positive prognosis. Approval to include cases as part of this presentation has been provided by the local HREC Chair.L6353006932021-06-22 <br />
