Pre-Sacral Giant Cell Tumour Excision through Posterior Approach

Abstract

Giant cell tumor (GCT) are well expansile, osteolytic lesion, with narrow transition zone at epiphysiometaphyseal region, commonly seen at ends of long bones accounting for approximately 5% of all primary bone tumors in adults. GCT in sacrum is the fourth commonest site after long end of bones, knee and radius, accounting for 1.7-8% of all GCTs [1-4]. Primary sacral tumor is rare and have incidence rate of 1 in 46,000 hospital admissions according to Ross and 1 in 30,000 according to Dockerty. GCTs are more common in Asia about 20% when compared to 4-5% in West [5-7].
