    AbstractThe objective of this study was to develop a technique which would permit access to the entire contents of long bones using a minimally invasive approach. Vascular catheterization techniques were used to allow access to the entire marrow cavity through a minimal percutaneous approach. A new device was also developed to reach the epiphysis of the long bone. The study was performed on animal and human anatomical specimens. A percutaneous approach was made through the bone shaft from a remote entry site using principles from endoscopy in an ex vivo experiment. This method may become an alternative technique when a direct approach to lesional sites in long bones is dangerous or impossible. For example, it could be used in cases of preventive cement injections in weakened bones.
