Study of bone tumours: (a comparison of drill with open biopsy).

ABSTRACT

This study was undertaken to find out the frequency of bone tumours and to evaluate the effectiveness of drill biopsy for tumourous bony lesions. A total of 182 cases of bone tumours and tumour-like lesions were studied histopathologically. Of these, 100 (54.95%) cases were found to be malignant, 45 (24.73%) benign and 28 (15.38%) tumour-like lesions. A total of 38 drill biopsies were performed where 29 cases had corresponding open biopsies. Of these, 22 cases (75.86%) had concordances in diagnosis. The overall success of drill biopsy was 73.68%.
