Abstract
Control) fibula but did not deliver any current. An undisplaced fracture of each fibula in a rabbit was permitted to heal for eighteen days. The fracture in one fibula of each animal was subjected to a ten microampere galvanic current, the electrodes being placed in various positions relative to the fracture. Leads were placed in the opposite (control) fibula but did not deliver any current. Each fibular fracture was studied by roentgenogram, stressed for rigidity, and evaluated microscopically. The evidence strongly suggests that a cathodal current of this intensity placed within the fracture site stimulates fracture healing.
