Surgical treatment of primary tumours of the innominate bone

9 cases of primary malignant tumours of the pelvis were treated in our department from 1981 to 1987. There was three chondro-sarcomas, one giant cell tumour and five had soft tissue tumours. One has a classical hemipelvectomy while eight had limb preservation surgery performed. In this later group., three had type I (Enneking) resection, three combined type II/III and one a type III resection. Four patients have died since and three deaths were related to surgery and its complications. As to date, no local recurrences has occurred in those living (up to 7 years' follow up). We feel that local resection with limb preservation provides adequate local control of tumour. Various reconstructive procedures to cover skin defects, and reconstruct stability of the pelvis or create hip stability were also performed. Patients with no previous irradiation has less mobidity and tend to do well.
