Musculoskeletal neoplasms: biopsy and intervention

Abstract

Percutaneous core needle biopsy and fine-needle aspiration are safe and cost-effective methods and can be important steps in the workup of a bone or soft tissue lesion. These procedures should be performed in collaboration with the orthopedic oncologist who performs the definitive surgery. In the extremities, attention to compartmental anatomy is paramount. With frozen section evaluation at the time of biopsy, the chances of a nondiagnostic specimen necessitating rebiopsy are minimized. The principles underlying the percutaneous approach to various lesions are valuable and can be applied to minimally invasive percutaneous therapy for bone and soft tissue lesions.
