Twenty-three patients with displaced supracondylar intercondylar fractures of the humerus have been treated using open reduction and internal fixation with a specifically designed contoured plate. One half of the fractures had significant comminution, and one third were open. At the time of review all fractures had united. There was an average 10° loss of extension and a 60° loss of flexion as compared with the opposite elbow. Two patients demonstrated loss of fixation on follow-up radiographs. In both cases, comminuted fractures in elderly patients were treated with continuous passive motion following internal fixation. Early operation with rigid fixation of comminuted supracondylar and intercondylar fractures of the humerus will yield satisfactory results. Poor results are associated with delay in surgery, significant associated injury to the same limb, and too early motion in patients with inadequate fixation.
