Impedence osteography: clinical applications of a new method of imaging fractures.

Fracture healing usually proceeds without difficulty. However, the diagnosis of delayed or non-union is not simple and can present difficulties in management. Normal fracture healing is briefly reviewed along with some methods of assessing the progress of union. The results of using the technique of impedence osteography in a preliminary study of fracture healing are presented. These indicate that the technique can clearly show a fracture and differentiate between normal bone, a united fracture and a non-union.
