Appropriate treatment of an atrophic nonunion of the ulna includes open reduction and internal fixation with autogenous bone grafting. The atrophic nature of the nonunion reveals that biology, and not necessarily stability, is the major issue of the nonunion. The referenced article by Ring et al reviews a case series of these patients and found that even in the face of significant preoperative bone resorption, good clinical outcomes and union rate is possible with open plating and grafting. The article by Street reviews intramedullary nailing/pinning of the forearm, and found a 7% nonunion rate with this technique.
