[Significance of biopsy in patients with osteoarticular tumors].

Author describes the place of biopsy in the diagnosis of osteoarticular tumors. Attention is called to the determination of the optimal site of the biopsy according to the different regions of the body. His opinion is that in malignant osteoarticular tumors biopsy with surgical exposure may be suggested now too. The field of indication for the needle biopsy is small. (e.g. proving metastasis etc.) With an adequate technique of the removal of samples the proportion of the local recurrence in limb saving operations can be reduced.
