The authors of this čase review present three cases of posttraumatic pseudoarthroses as complications of open fractures of the forearm and the course of their treatment. External fixation with the Ilizar external fixation apparatus and bridging spongioplasty was applied in all patients. In the first presented čase, the external fixation and spongioplasty was required after resection of the atrophic posttraumatic pseudoarthrosis. In the remaining two cases, furthermore, transposition of the distal fragment of the rádius using distraction in order to correct its position against the distal part of the ulna, was required. The pseudoarthroses healed in all three subjects. The čase review highlights the key significance of the external fixation method and the massive spongioplasty.
