Abstract:
For correction of malunited distal radius fractures, the use of the external fixator in radio-radial application was assessed. The device has been used for one-stage correction with corticocancellous bone blocks as well as with hemicallotasis for correction of dorsal angulation. The technical application is described and the use of the external fixator defined. Fourteen patients were treated with radio-radial application, seven of those were corrected with callus distraction. The mechanical possibilities of the fixator allowed complete correction of the malunion.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
