From 1991 to 1998, 23 humeral fractures has been treated using the Orthofix external fixator. Average age of the patient was 42 y and average follow-up 55.5 m. Initial trauma was: 13 traffic accidents, four falls at home, two devastating farming accidents, two sports accidents, one aggression and one gun accident. AO classification was used and location of the fracture was classified using Hackethal classification modified by de la Caffinière. Majority of fractures were located at the one-third distal humerus and the majority was also comminuted. At follow-up, elbow range of motion was 130 degrees, shoulder range of motion 161 degrees, external rotation 69.5 degrees and internal rotation 92.5 degrees. Using the classification of Stewart and Hundley, eight excellent, seven good, three fair and two bad results were obtained. There were no postoperative radial nerve palsy. Two external fixators had to be removed because of pin mobility. Failures were: non union and pin mobility in one patient which has to be reoperated on; two non unions have been grafted on and plated. There were no malunion in the postoperative X-rays. This device is our favourite for this type of injury because of its rigidity and the possibility of secondary dynamization. The external fixator was removed after union: this explains the long delay of union in our series.
