PURPOSE: Nonunion of the radial neck poses an enormous challenge for treating surgeons. It is a very rare complication of the radial neck with limited experiences. In this current major study, the authors report of their own experiences concerning this problem. METHODS: 11 patients with severe displaced radial neck fracture Metaizeau type IV with elbow dislocation and 2 ongoing fractures. 9 fractures had to be treated with open reduction, six with intramedullary nailing, two with K-wires and one with periosteal suture fixation. In two children, aged 4 and 5, the fracture was not diagnosed initially. The patients showed a successful reduction intraoperatively. RESULTS: All patients developed nonunion of the radial neck. 9 out of 11 children presented with pain and 5 out of 11 with valgus deformity. All children underwent surgical management of the complications. 3 children received a debridement of the elbow joint with resection of the fragmented radial head. 7 cases needed a following reduction, spongiosa-plasty and periosteal flap reconstruction and plate osteosynthesis. One patient received radial intramedullary pinning. All nonunions showed reunion. All patients with obtained radial head showed significant improvement concerning complaints and range of motion. Only one child showed a slight deterioration in range of motion. Children with resected radial head showed good range of motion but complaints and instability in loaded joint needing further surgical treatment. CONCLUSION: Treatment of radial neck nonunion in children should not be delayed until pain, deformity and limited function occurs because this goes along with severe transition of the radial head right up to bone atrophy.
