External compression of forearm nonunion. A report on 6 cases

We treated 6 patients with 7 cases of aseptic nonunion of the forearm with external fixation and compression (Orthofix) without open reduction and bone grafting. By turning a screw on the side of the bar, compression was carried out until the nonunion gap with radiographically obliterated, usually within 2 weeks. After compression had stopped, the external fixator was retained during the following period of healing and bone remodeling. Healing of the nonunions was seen after 7 (4-11) weeks. 5 patients obtained normal mobility, while 1 had slightly restricted supination and pronation.
