The tactics and technique of musculoskeletal biopsy

The treatment of musculoskeletal neoplasms and infection is usually based on an initial diagnostic biopsy.Prior to biopsy, a hypothesis should be formed about the most likely diagnosis and a differential diagnosis. These deliberations should consider whether the lesion is a primary benign or malignant tumour, a metastasis, a haematological problem or an infection.A tactical plan should be developed which evaluates the necessity, the risk, the approach and finally defines the technique of biopsy most likely to achieve a representative result in the clinical case.In developing this technical approach, the pitfalls should be anticipated, i.e. inadequate sampling, difficulty of pathological interpretation and contamination.The tactical approach should be developed in conjunction with a multi-disciplinary team together with appropriate pre-biopsy imaging.
