Abstract
A non-rigid bone fracture fixator comprising first and second bone pins for connection either side of a bone fracture and primary and secondary supports clamped to the bone pins by respective fixed and guide clamps. The second support and the guide clamps are connected slidably to the primary support such that the supports may execute a controlled degree of movement with respect to one another. A compression spring is arranged to bias apart the supports longitudinally of a fixated limb. In use the fixator is applied to the limb with the fracture in slight compression. Exercise of the limb then produces varying degrees of fracture compression stimulating bone callus formation and rapid healing. The fixator may include actuating means to provide passive fracture exercise for immobilized patients.
