Union of the ulna was achieved at 3 months after surgery and the external fixator was removed (Fig. 5a). The patient was followed up until 18 moths postoperatively (Fig. 5b).
(a and b) 18 months postoperatively. The patient is able to perform: (a) Full flexion of his elbow as is indicated by the ability to touch his chin and (b) Almost full extension and 70  supination.
