Imaging following surgery for primary appendicular bone tumours

Abstract

Primary bone tumours are uncommon, with sarcomas accounting for < 0.2% of all malignancies. The survival rate of primary bone sarcomas hassignificantly improved due to (neo)adjuvant therapy, while improved surgical techniques and development of new prostheses have shifted the surgical focusfrom amputation to limb preservation in the vast majority of patients. A wide variety of surgical options are available for the treatment of primary bonetumours which depend upon histological diagnosis, their appearance at the time of presentation and response to any (neo)adjuvant therapy as required. Thisreview is intended to help radiologists familiarise themselves with the management of primary appendicular bone tumours and expected normal postoperativeappearances for the various surgical techniques, and to recognise potential complications.
