Clavicular nonunion. 31/32 healed after plate fixation and bone grafting.

We report the long-term results in 32 patients with established nonunion of the clavicle; 15 treated with AO Dynamic Compression Plate and autologous cancellous bone graft and 17 treated with an AO reconstruction plate and autologous cancellous bone graft. The patients were followed up for a mean of 8 (4-21) years from injury and 7 (4-12) from non-union operation, both by clinical review and radiographs. 31/32 nonunions united successfully. One fracture which initially failed to unite was replated and subsequently united. 6 compression plates and 7 reconstruction plates were removed for discomfort or cosmesis. None broke. Both plates give equally good results, but we feel that the reconstruction plate is easier to contour to the complex form of the clavicle.
