biopsy

Region specific approaches

Theory

- want to traverse one muscle / one compartment

- keep away from NV bundle

- as a rule perform open biopsy through compartment the tumour is in

- this is the compartment that will require surgical removal in wide excision

- direct approach without going through muscle if possible i.e. tibia, distal ulna
